detailed description

The invention will now be further described with reference to the drawings and preferred embodiments.

As shown in Figures 1 through 4, a table tool includes a cutting body 20 and a frame 22 supporting the cutting body 20. The cutting body 20 includes a casing 24 extending in the longitudinal direction, and a motor (not shown) provided in the casing 24. The working head 26 and the frame 22 driven by the motor are provided with a table 30. The table 30 has a first support plane 32 and a second support plane 34 for selectively supporting the workpiece, and the first support plane 32 and the second support plane 34 are disposed opposite each other. The table 30 is also provided with a hole 35 through which the working head 26 passes, the hole 35 extending from the first support plane 32 to the second support plane 34, the table tool further comprising a switch for opening and closing the motor.

The cutting body 20 is operatively movable relative to the frame 22 to provide the desktop tool with the first job Status and second working status. In the first working state, the first supporting plane 32 is used as the working surface, and the working head 26 is moved away from or extends through the first supporting plane 32; in the second working state, the second supporting plane 34 is used as the working surface, and the working head 26 is extended. Through the first support plane 32 and the second support plane 34. Thus, the bench tool of the preferred embodiment has two operating states, thereby enabling the bench tool to meet a variety of processing needs.

As shown in FIG. 1 and FIG. 2, in the first working state, the workpiece to be processed is placed on the first support plane 32, the housing 24 of the cutting body 20 is located above the table 30, and the working head 26 is away from or through the first Support plane 32 for machining workpieces. Here, the working head 26 can be set as a milling cutter, a slotting knife, or the like. At this time, profiling or grooving can be performed on the surface of the workpiece to be processed away from the first support plane 32. Under such working conditions, the field of view is very good, and the operator can clearly see the processing of the workpiece, thereby facilitating the profiling of lettering, trenching and the like.

As shown in Fig. 3 and Fig. 4, in the second working state, the entire desktop tool is flipped by 180 degrees with respect to the first working state. In the second operational state, the workpiece being machined is placed on the second support plane 34, the housing 24 of the cutting body 20 is located below the table 30, and the cutting body 20 is operatively movable to extend the working head 26 through A support plane 32 and a second support plane 34 are used to machine the workpiece. At this time, processing such as grooving can be performed on the surface of the workpiece to which the workpiece is in contact with the second support plane 34. In this working state, the size of the workpiece to be machined is not limited, and a large workpiece can be processed. In addition, the workpiece can be cut through from the end. Therefore, the desktop tool can realize the conversion between the two working states by a simple flip operation, which is very convenient. At the same time, the benchtop tool can meet a variety of processing needs.

In addition, the frame body 22 has a frame structure, so that the table tool is light in weight and convenient for the turning operation, thereby realizing the transition between the two working states.

With further reference to FIG. 5, since the table tool has two working states, correspondingly, the frame body 22 has a first support portion 36 and a second support portion 38, which are selectively supported, the first support portion 36 and the second support portion. 38 relative arrangement, referring again to Figures 1 and 2, the first support portion 36 serves as a support when the table tool is in the first operational state. Referring again to Figures 3 and 4, the second support portion 38 serves as a support when the table tool is in the second operational state.

The frame 22 also includes a post 40 that connects the first support portion 36 and the second support portion 38. The first support portion 36, the post 40, and the second support portion 38 form a cavity that houses the cutting body 20. The support leg 42 is detachably provided on at least one of the first support portion 36 and the second support portion 38. When the table tool is in the first working state, that is, the first support portion 36 serves as a support, the support leg 42 is disposed on the first support portion 36. When the table tool is in the second working state, that is, the second support portion 38 serves as a support, the support leg 42 is disposed on the second support portion 38.

In the preferred embodiment, the support leg 42 is fixedly disposed on the first support portion 36 or the second support portion 38 by the cam mechanism 44, thereby achieving quick disassembly between the support leg 42 and the frame body 22. In addition, in order to stabilize the support, the support leg 42 is further provided with two foot pads 46, and the foot pads 46 can be made of rubber.

In the present embodiment, the first support portion 36 is composed of two tubes 37, and the second support portion 38 is composed of two tubes 39, and the support legs 42 are selectively disposed on the tube 37 or the tube 39. And the cam mechanism 44 is disposed on the support leg 42. When the table tool is in the first working state, two supporting legs 42 are respectively disposed on the two pipes 37 constituting the first supporting portion 36. When the table tool is to be switched to the second working state, the table tool is first turned 90 degrees, the column 40 is brought into contact with the ground, and the two supporting legs 42 and the cam mechanism 44, the supporting legs 42 and the cam are removed from the first supporting portion 36. The mechanism 44 is detached together as a whole, and then the two supporting legs 42 are attached to the two pipes 39 constituting the second supporting portion 38 through the cam mechanism 44, and finally the table tool is further turned 90 degrees in the above-mentioned turning direction. Put the desktop tool in the second working state. Therefore, the desktop tool can realize the conversion of the two working states by simple supporting and dismounting operations, which is very convenient.

Referring again to Figures 5 and 6, the cam mechanism 44 includes a cam handle 48, a shaft 50 for mounting the cam handle 48, a bolt 52 and a nut 54. The tube 37 and the tube 39 are each provided with a long slot 56 through which the bolt 52 passes. The tubing 37 and the long groove 56 and the support leg 42 on the tubing 39 are passed through the cam handle 48 and the shaft 50 to engage with the nut 54, thereby connecting the support leg 42 to the frame body 22.

The long groove 56 in the tube 39 of the second support portion 38 will now be described in detail. The long groove 56 has a longitudinal portion 58 and an end portion 60. The end portion 60 is wider than the length of the longitudinal portion 58. The end portion 60 The bolt head of the bolt 52 can be allowed to pass, and the bolt head of the retaining bolt 52 of the longitudinal portion 58 passes. Therefore, when the support leg 42 is mounted, the bolt head of the bolt 52 passes through the end portion 60, and then the support leg 42 and the cam are made. The mechanism 44 slides relative to the second support portion 38 such that the bolt head of the bolt 52 is remote from the end portion 60 until it is at the elongated portion 58, such that the bolt head of the bolt 52 is stopped by the elongated portion 58 and the cam handle 48 is tightened. Thereby, the support leg 42 is locked to the second support portion 38. When the support leg 42 is to be removed, in contrast to the above-described operational steps, the cam handle 48 is first loosened, and then the support leg 42 and the cam mechanism 44 are opposed to The second support portion 38 slides until the bolt 52 is at the end portion 60, so that the bolt head of the bolt 52 is passed out from the end portion 60, and the support leg 42 and the entire cam mechanism 44 are removed.

A guard rail 62 for abutting against the workpiece is detachably provided to the frame body 22. The guard rail 62 is mounted in the same manner as the support leg 42 and the same cam mechanism 44 is used to achieve quick disassembly of the guard rail 62, and will not be described in detail herein. As shown in FIGS. 1 and 2, when the table tool is in the first working state, the guard rail 62 is mounted on the first support portion 36 of the frame body 22, and the guard rail 62 is located above the first support plane 32. In addition, the guard rail 62 is slidable relative to the frame 22 to adjust the distance between the guard rail 62 and the work head 26 as needed for processing. Of course, the guardrail 62 can also be placed on the workbench 30.

When the table tool is switched from the first working state to the second working state, the guard rail 62 needs to be detached, and then the guard rail 62 is mounted on the other side of the first supporting portion 36, and the guard rail 62 is located above the second supporting plane 34. At the same time, the guard rail 62 is located outside the cavity of the frame body 22.

In addition, in order to facilitate the processing of the abutting surface and the processing surface at an oblique angle, a plane angle device (not shown) may be disposed on the frame 22 or the table 30.

With further reference to Figure 7, the table tool includes a movement mechanism 86 that moves the cutting body 20 relative to the frame 22.

The moving mechanism 86 includes a first connecting member 89 disposed on the housing 24, and an operating member 88 pivotally disposed relative to the frame body 22, wherein the operating member 88 is slidably disposed on the first connecting member 89. The moving mechanism 86 further includes a guide rail 114 disposed on the frame body 22, and a guide member 116 disposed on the housing 24 to cooperate with the guide rail 114. Of course, the guide rails 114 may also be disposed on the housing 24, and correspondingly, the guide members that cooperate with the guide rails 114 are disposed on the frame body.

In the preferred embodiment, the guide member 116 is pivotally disposed on the housing 24, and the guide member 116 is disposed as a roller 116. Thus, when the cutting body 20 is moved relative to the frame 22, the rolling friction between the roller and the guide rail 114 greatly reduces the resistance, making the movement of the cutting body 20 lighter. In addition, the roller 116 rotates about an axis perpendicular to the extending direction of the housing 24.

The guide member 116 is disposed on the mounting plate 122 by bolts 118 and nuts 120, and the mounting plate 122 is fixedly coupled to the housing 24 by screws (not shown). In the preferred embodiment, the mounting plates 122 are disposed in two, and each of the mounting plates 122 is provided with two guiding members 116. The guide rails 114 are provided in a V shape. The guide rail 114 has a first extending portion 124 and a second mating portion 126 extending longitudinally.

Preferably, the V-shape of the guide rail 14 is disposed facing the cutting body 20, so that the bench tool is compact in structure, reduces space occupation, and has low cost.

When the operating member 88 is operated to pivot the operating member 88 relative to the frame body 22, the pivoting of the operating member 88 drives the cutting body 20 to move in the vertical direction relative to the frame body along the guide rails 114 by the guide members 16. The distance between the working head 26 and the first support plane 32 and the second support plane 34 is adjusted to machine a groove of a certain depth.

The first connecting member 89 is provided with a hole 91 through which the operating member 88 is inserted. In the preferred embodiment, the first connector member 89 is pivotally disposed on the housing 24. Of course, the first connecting member 89 can also be slidably disposed on the housing 24, specifically, a chute is disposed on the housing 24, and the first connecting member 89 is slidably disposed in the sliding slot.

The first connecting member 89 is symmetrically disposed with respect to the housing 24. The operating member 88 has two free ends 94 that are slip-fitted with the first connecting member 89 and an operating portion 95 that connects the two free ends 94 and is held by the operator. The operating member 88 is provided as a U-shaped member.

In order to save cost, in the preferred embodiment, the first connecting members 89 are disposed in two and symmetrically disposed on opposite sides of the cutting body 20, the two free ends 94 of the operating member 88 and the two first connecting members 89 Slip mating.

The housing 24 is provided with a seat body 96 for receiving a first connecting member 89. The seat body 96 is provided with a first stopping portion 98 and a second stopping portion 100. The first stopping portion 98 and the second stopping portion 100 are provided. The pivoting angle of the operating member 88 relative to the frame 22 is restricted, thereby controlling the amount of displacement of the cutting mechanism 86 relative to the movement of the cutting body 20. The base 96 is provided with a cover 102, and the first connecting member 89 is received between the base 96 and the cover 102.

The moving mechanism 86 also includes a retaining device 103 that holds the operating member 88 in place. The holding device 103 can hold the operating member 88 in the first position and the second position. Referring again to Figures 1 and 4, in the first position, the operating member 88 is away from the table 30; referring to Fig. 2 and Fig. 3, the second position The operating member 88 is adjacent to the table 30.

In the preferred embodiment, the retaining device 103 is a compression spring 103 disposed between the operating member 88 and the housing 24. Of course, the retaining device 103 can also be provided with a stop pin or a steel ball, etc., the stop pin or the steel ball can be telescopically or pluggably provided on the housing 24 or on the operating member 88, correspondingly, with the stop pin or steel Ball A mating portion such as a slot or a hole is provided on the operating member 88 or on the housing 24.

In order to facilitate the installation of the operating member 88 and the compression spring 103, the operating member 88 is pivotally disposed on the frame body 22 via the second connecting member 104. One end of the second connecting member 104 is pivotally disposed on the frame body 22, and the second connection is The other end of the member 104 is provided as a sleeve structure, sleeved on the operating member 88, and the operating member 88 and the second connecting member 104 are fixed together by a pin (not shown). This setting is very convenient for installation.

The pressure spring 103 is disposed on the operating member 88. One end of the compression spring 103 is stopped by the second connecting member 104, and the other end of the compression spring 103 is stopped by the seat body 96 and the cover body 102. The force of the compression spring 103 is sufficient to maintain the operating member 88 in position relative to the cutting body 20.

With further reference to Figures 8 and 9, the table tool further includes an elevation mechanism 66 for adjusting the height of the cutting body 20, i.e., for adjusting the working head 26 relative to the first support plane 32 and the second support plane 34. the distance.

The height adjustment mechanism 66 is coupled to the frame body 22 and the moving mechanism 86. The height adjusting mechanism 66 includes a first mating member 68 connected to the frame body 22 and a second mating member 70 coupled to the moving mechanism 86 and engaging with the first mating member 68.

Further, the first mating member 68 is a lead screw 68 fixed to the frame body 22. The second mating member 70 is a nut 70 connected to the housing 24 and mated with the lead screw 68. Therefore, when the nut 70 is rotated relative to the lead screw 68, the cutting body 20 can be moved relative to the lead screw 68, so that the cutting body 20 can be moved relative to the frame body 22. Of course, the height adjustment mechanism 66 can also use a worm gear or a rack and pinion mechanism in addition to the screw nut mechanism. If the first adapter 68 is provided as a worm or a rack, the second adapter is accordingly provided as a turbine or a gear.

Further, the first adapter member 68 is coupled to the frame body 22, and the second adapter member 70 is coupled to the housing 24 via the moving mechanism 86. That is, the second adapter 70 is coupled to the operating member 88 of the moving mechanism 86.

Further, in order to facilitate the mounting of the lead screw 68, a mounting member 72 is detachably coupled to the frame body 22 by bolts (not shown), and the lead screw 68 is attached to the mounting member 72 via a nut 74 and a pad 76.

Moreover, in order to facilitate the adjustment of the height adjustment mechanism 66, the height adjustment mechanism 66 further includes a first bevel gear 78 disposed coaxially with the nut 70, and a second bevel gear 80 meshing with the first bevel gear 78 for receiving the first A bevel gear 78 and a gearbox 82 of the second bevel gear 80, and a drive member 84 for the operator to drive the movement of the second bevel gear 80. In the preferred embodiment, the drive member 84 is configured as a hand wheel 84 for ease of operation. In the preferred embodiment, the axis of rotation of the hand wheel 84 is perpendicular to the direction of extension of the rail 14 to allow the operator Easy to operate. Further, the rotation axis of the roller 1 16 is perpendicular to the rotation axis of the hand wheel 84, so that the cutting body 20 can smoothly move along the guide rail 114.

In addition, the second bevel gear 80 and the gear box 82 are coupled to the housing 24 of the cutting body 20 such that when the rotating hand wheel 84 drives the second bevel gear 80 to rotate, the first bevel gear 78 can be rotated, and the nut 70 is opposite. Rotating on the lead screw 68, since the lead screw 68 is stationary, the nut 70, the gear case 82, the second bevel gear 80 and the cutting body 20 move linearly with respect to the lead screw 68 in the axial direction of the lead screw 68. .

Preferably, the operating member 88 is pivoted coaxially with the second bevel gear 80. The operating member 88 is pivotally coupled to the gearbox 82 or to the gear shaft 106 of the second bevel gear 80 or to the hand wheel shaft 108 of the hand wheel 84. Preferably, the operating member 88 is pivotally coupled to the gearbox via the second connector 104. 82 is on the gear shaft 106 of the second bevel gear 80 or on the hand wheel shaft 108 of the hand wheel 84. Thus, when the rotating hand wheel 84 drives the second bevel gear 80 to rotate, the first bevel gear 78 can be rotated, the nut 70 rotates relative to the lead screw 68, and since the lead screw 68 is fixed, the nut 70, the first The bevel gear 78, the second bevel gear 80, the gear case 82, the cutting body 20, and the moving mechanism 86 move linearly with respect to the lead screw 68 in the axial direction of the lead screw 68.

In addition, the gear case 84 can also be used to prevent dust from falling onto the first bevel gear 78 and the second bevel gear 80, thereby ensuring smooth transmission between the first bevel gear 78 and the second bevel gear 80. For ease of installation, the gearbox 84 is configured in two half-shell configurations.

Referring again to Figures 1 and 2, the first working state is taken as an example. When the contouring or milling is performed on a workpiece (not shown), the working head 26 is replaced with a corresponding working head. First, the distance from the groove to be processed to the end surface of the workpiece is determined, and then the distance between the guard rail 62 and the working head 26 is adjusted according to the above distance, the workpiece is placed on the first support plane 32, and the workpiece is abutted against the guard rail 62, and then The operating member 88 of the moving mechanism 86 is pulled in the direction of the table 30, and the operating member 88 is pulled toward the table 30 before the workpiece is processed, so that the operating member 88 is opposed to the nut 70, the gear box 82, and the first cone. The gear 78 and the second bevel gear 80 pivot, thereby causing the cutting body 20 to linearly move along the guide rails 14, thereby finally ensuring that the operating member 88 is in the second position adjacent to the table 30. At this time, the cutting body 20 is moved relative to the nut 70. Then, the hand wheel 84 is rotated to move the cutting body 20 relative to the frame body 22. At this time, no displacement amount is generated between the nut 70 and the cutting body 20, and the nut 70, the gear box 82, the cutting body 20 and the moving mechanism are relatively fixed. 86—with respect to the lead screw 68 along the lead screw 68 The axis direction moves linearly until the working head 26 reaches a predetermined depth at which the workpiece is to be machined. Next, an operation switch (not shown) is used to open the motor (not shown;), and the workpiece is advanced along the guardrail 62 for machining operation. After the workpiece is processed, the operating member 88 is pulled away from the table 30 until the operating member 88 is at a first position away from the table 30. At this time, the operating member 88 drives the cutting body 20 relative to the frame 22 and the nut 70. The rapid movement causes the quick return of the cutting body 20 to the initial position, that is, the non-machining position, so that the working head 26 is away from the workpiece to be processed, and finally the workpiece can be conveniently taken out. In addition, when the workpiece of the same thickness is processed again at the same depth, the cutting body 20 does not need to be re-adjusted. After the workpiece is placed, the operating member 88 only needs to be pulled again in the direction of the table 30, so that the operating member 88 is located close to The second position of the table 30 is such that the working head 26 can be brought to the above-described machining position, and then the workpiece can be machined.

The moving mechanism 86 can not only enable the cutting body 20 to quickly return to the non-machining position, but also perform the same depth processing operation on the workpiece of the same thickness without the need of the adjustment and the tool setting by the height adjusting mechanism 66, and only need to pull the operating member 88 enables the cutting body 20 to be quickly returned to a non-machining position, and can be quickly processed.

Of course, if non-linear profiling is performed, the guardrail can be removed and the workpiece can be arbitrarily driven according to the shape to be machined. Other operations are the same as the above linear processing. In addition, accessories such as a plane angler can be attached to the frame 22 or the table 30 according to the processing needs.

With further reference to Figures 3 and 4, the bench tool can also be used for milling when the table tool is in the second working state, the depth of the milling slot being equal to the distance that the working head 26 extends out of the second support plane 34, at which time the operating member 88 It may be located at a first location remote from the workbench 30 or a second location near the workbench 30. Rotating the hand wheel 84 moves the cutting body 20 relative to the frame 22 such that the working head 26 extends through the first support plane 32 and the second support plane 34, the machining depth of the workpiece being equal to the working head 26 extending out of the second support plane 34 distance. Alternatively, the guardrail 62 or the planar angler can be mounted to the frame 22 or the table 30 according to the processing needs, and the guard rail 62 or the plane angler is located on the second support surface 34. Of course, the guardrail or plane angler can also be removed according to the processing needs.

When the table tool is in the first working state and the second working state, the working head 26 can be replaced as needed. As shown in FIG. 1, when the table tool is in the first working state, the rotating hand wheel 84 moves the cutting body 20 relative to the frame 22 until the working head 26 is away from the first supporting plane 32, leaving a distance to the replacement working head 26. A certain operating space is provided, so that the working head 26 can be easily replaced. As shown in Figure 4, Similarly, when the table tool is in the second working state, if the working head 26 needs to be replaced, the hand wheel 84 can be reversely rotated to move the cutting body 20 relative to the frame 22 until the working head 26 moves out of the first support plane 32 and the second. The support plane 34 is spaced apart from the first support plane 32, thereby providing a certain operating space for the replacement working head 26, and it is also very convenient to replace the working head 26.
