A rocking space 51 is maintained between the guide rod 21 and the guide hole 22.
As shown in fig. 10, in order to facilitate the mechanical arm 6 to replace the gripping portions with different specifications to adapt to the die adjusting nuts 1 with different inner diameter sizes, the sixth shaft 7 of the mechanical arm 6 is connected with a support 30 through a quick-change disc 29, and the first gripping portion 8 and the second gripping portion 9 are both disposed on the side surface of the support 30. In this embodiment, a specific technical solution of the quick-change disc 29 is disclosed in the patent document with the publication number CN112815169a, and will not be described in detail.
As shown in fig. 11, in order to facilitate storage of the support 30, the support 30 is provided with an annular flange 31 extending outwardly from the face edge of the disc 29, and an escape space 32 is maintained between the flange 31 and the first and second gripping portions 8, 9. The sleeve part machining workstation further comprises a support frame 33, a plurality of placing plates 34 with the plate surfaces in a horizontal state are arranged on the support frame 33, the placing plates 34 are sequentially arranged and distributed in a step mode, and a placing groove 35 for the support 30 to enter along the plate surface direction of the placing plate 34 is formed in the side edge, close to the adjacent lower placing plate 34, of each placing plate 34. When the support 30 enters the placement groove 35, the flange 31 abuts against the upper plate surface of the placement plate 34 and the first grabbing portion 8 and the second grabbing portion 9 are located below the placement plate 34, so as to complete the storage of the support 30 and the grabbing portions.
As shown in fig. 11 and 12, in order to prevent the dust from being deposited on the quick change tray 29 on the stored holder 30, a shutter 36 is covered above the placement groove 35, and a driving mechanism 37 for driving the shutter 36 to flip up and down is provided on the side of the placement plate 34 where the placement groove 35 is not provided. Specifically, the driving mechanism 37 includes a pivot seat 38 disposed on the upper surface of the placement plate 34, a first connecting rod 39 disposed above the pivot seat 38 and having one end fixed to the baffle 36, and a second connecting rod 40, where one end of the second connecting rod 40 is pivoted to the first connecting rod 39 at a position far away from the baffle 36, and the other end is pivoted to the pivot seat 38, and an air cylinder 41 is disposed on a side of the placement plate 34 where the placement groove 35 is not disposed, and a push rod 42 of the air cylinder 41 is disposed vertically and pivoted to one end of the first connecting rod 39 far away from the baffle 36. When the push rod 42 of the cylinder 41 is extended upward, the first link 39 drives the shutter 36 to turn down to cover the face of the support 30 having the disc 29. Conversely, when the push rod 42 of the air cylinder 41 is contracted downwards, the first connecting rod 39 drives the baffle 36 to turn upwards, so that the quick-change disc 29 on the support 30 or the placing groove 35 on the placing plate 34 is exposed, and the mechanical arm 6 is convenient to take and place the support 30.
As shown in fig. 12, in order to prevent the barrier 36 from excessively moving down and to secure stability in the closed state of the barrier 36, the upper plate surface of the placement plate 34 is provided with two holders 43 for holding the shafts of the first links 39 to prevent the barrier 36 from excessively moving down. In order to improve the matching precision between the support 30 and the placement groove 35, the upper plate surface of the placement plate 34 is provided with two positioning pins 44, and one side of the convex edge 31, which is close to the placement plate 34, is provided with two positioning holes 45 for the two positioning pins 44 to be inserted in a one-to-one correspondence manner.
As shown in fig. 11, 12 and 13, in order to improve the safety of the mechanical arm 6 when taking and placing the support 30, a first proximity sensor 46 is disposed on a side of the support 30 away from the quick-change tray 29, and a controller 47 is coupled to the first proximity sensor 46, and the controller 47 is preferably a PLC. The mechanical arm 6, the quick-change disc 29 and the air cylinders 41 on each placing plate 34 are controlled by a controller 47, and a plurality of starting units 48 which are in one-to-one correspondence with the plurality of air cylinders 41 and second proximity sensors 49 which are arranged on the upper plate surfaces of the plurality of placing plates 34 are also coupled to the controller 47. The activation unit 48 is preferably a push switch. Each of the second proximity sensors 49 is disposed at one side of the placement groove 35 of the corresponding placement plate 34 to detect whether the flange 31 abuts against the upper plate surface of the placement plate 34. When the second proximity sensor 49 does not detect that the flange 31 abuts against the upper plate surface of the corresponding placement plate 34, indicating that the support 30 is not installed in the placement groove 35, the controller 47 controls the push rod 42 of the corresponding cylinder 41 to retract downward, so that the first connecting rod 39 on the corresponding placement plate 34 drives the baffle 36 to flip up, and the corresponding placement groove 35 is exposed.
When the support 30 connected to the mechanical arm 6 approaches to the upper side of the placement plate 34, the first proximity sensor 46 can detect whether the baffle 36 is covered over the placement groove 35, if the baffle 36 is not covered over the placement groove 35, the controller 47 controls the mechanical arm 6 to place the support 30 in the placement groove 35 of the current placement plate 34, when the second proximity sensor 49 on one side of the placement groove 35 detects that the flange 31 on the support 30 abuts against the upper plate surface of the corresponding placement plate 34, the controller 47 controls the quick-change tray 29 to cut off the connection between the support 30 and the sixth shaft 7 and controls the sixth shaft 7 of the mechanical arm 6 to be far away from the support 30, so as to finish the storage of the support 30, the first grabbing portion 8 and the second grabbing portion 9. When the storage of the support 30 is completed, the controller 47 controls the push rod 42 of the air cylinder 41 to extend upwards, so that the first connecting rod 39 on the corresponding placing plate 34 drives the baffle 36 to cover the upper part of the corresponding placing groove 35, thereby preventing dust on the quick-change tray 29 on the current support 30.
Otherwise, if the baffle 36 is already covered above the placement groove 35, which means that the support 30 is already stored in the placement groove 35 corresponding to the baffle 36, the controller 47 controls the mechanical arm 6 to bring the support 30 away from the current placement plate 34, so as to avoid collision between the supports 30, and improve safety.
In order to enable the mechanical arm 6 to select a gripping part with a corresponding specification according to the inner diameter size of the die adjusting nut 1, after the starting unit 48 responds to external trigger, the controller 47 controls the push rod 42 of the corresponding air cylinder 41 to shrink downwards, so that the first connecting rod 39 on the corresponding placing plate 34 drives the baffle 36 to flip upwards, thereby exposing the support 30 stored in the corresponding placing groove 35 and the quick-change disc 29 on the support 30, and facilitating the mechanical arm 6 to take the support 30. Meanwhile, the controller 47 controls the mechanical arm 6 to store the currently connected support 30 in the empty placing groove 35, and transfers the empty sixth shaft 7 to the position above the placing groove 35 with the baffle 36 turned up, so as to complete the butt joint of the sixth shaft 7 and the corresponding support 30 through the quick change disc 29, thereby completing the replacement of the support 30 and the grabbing part.
The specific use process is as follows:
before the workstation formally runs, the mechanical arm 6 needs to select and install the grabbing parts with corresponding specifications according to the inner diameter size of the die adjusting nut 1. Therefore, the operator first presses and triggers the starting unit 48 according to the required grabbing portion and the storage position of the support 30, so that the cylinder 41 corresponding to the starting unit 48 contracts the push rod 42 downward, and the first link 39 above the corresponding placement plate 34 drives the baffle 36 to turn up, so that the support 30 and the quick-change tray 29 stored in the current placement groove 35 are exposed. At this time, the controller 47 first controls the mechanical arm 6 to store the currently connected support 30 and the gripping portion in the empty placement groove 35 and cover the corresponding baffle 36 of the placement groove 35. In the storage process, the sixth shaft 7 of the mechanical arm 6 firstly makes the side of the support 30 with the first proximity sensor 46 face downwards, then places the part of the support 30 with the avoidance space 32 on the side of the placing groove 35 with the opening and moves the support 30 into the placing groove 35 along the direction of the plate surface of the current placing plate 34, so that the positioning holes 45 on the convex edge 31 are opposite to the positioning pins 44 on the placing plate 34 one by one. At this time, the mechanical arm 6 controls the sixth shaft 7 to lower the support 30 so that the positioning pin 44 is abutted with the positioning hole 45 until the convex edge 31 abuts against the upper plate surface of the placement plate 34, and the grabbing portion on the support 30 can be placed under the placement plate 34. In this state, the controller 47 controls the disc 29 to cut off the connection between the current holder 30 and the sixth shaft 7, so that the storage of the holder 30 and the grip portion can be completed. After the storage is completed, the second proximity sensor 49 mounted on the placement plate 34 can identify the storage state of the support 30 by using the proximity of the flange 31, so that the controller 47 controls the baffle 36 to cover the interface of the quick-change tray 29 on the support 30 through the corresponding cylinder 41, thereby playing a role in dust prevention and collision prevention.
After the original specification of the grabbing parts and the supports 30 are stored, the controller 47 controls the mechanical arm 6 to transfer the empty sixth shaft 7 to the position above the needed grabbing parts and the supports 30, and the butt joint of the sixth shaft 7 and the current supports 30 is completed by utilizing the quick change disc 29. After the docking is completed, the mechanical arm 6 lifts the support 30 slightly by the sixth shaft 7, so that the positioning pins 44 on the placement plate 34 are disengaged from the positioning holes 45 on the flange 31. Then, the holder 30 together with the grasping portion is taken out of the placement groove 35 along the plate surface of the placement plate 34.
After the support 30 and the gripping part are taken out, the metal working link of the die adjusting screw 1 can be formally entered. In the processing process, the mechanical arm 6 firstly grabs the die adjusting nut 1 to be processed on the feeding device 5 through the first grabbing part 8. In the material taking process, the three clamping jaws 15 on the first grabbing part 8 extend into the inner hole 14 of the die adjusting screw 1 from the A side shaft, then the extrusion plate 17 on the base 13 is driven to abut against the A side end face of the die adjusting screw 1, and the extrusion plate 17 is extruded towards the direction close to the base 13 against the elastic supporting force of the elastic compensation assembly 18, so that the clamping jaws 15 of the finger cylinder can extend into the inner hole 14 of the die adjusting screw 1 further. When the pressing plate 17 is pressed a certain distance, the three clamping jaws 15 of the finger cylinder are spread to complete the gripping of the workpiece, and the pressing plate 17 can be locked in a compressed state.
After the material taking is completed, the mechanical arm 6 transfers the first grabbing part 8 for clamping the workpiece and the empty second grabbing part 9 to the vicinity of the first numerically controlled lathe 3, and takes the die adjusting screw 1 on the side A after the processing in the fixture 10 of the first numerically controlled lathe 3 through the second grabbing part 9, and in the material taking process, the second grabbing part 9 takes the side A of the die adjusting screw 1 as a grabbing point. After the semi-finished workpiece on the clamp 10 is taken down, the first grabbing part 8 can clamp the newly clamped die adjusting nut 1 in the clamp 10 of the first numerical control lathe 3. In the clamping process, the side of the die adjusting screw 1B grabbed by the first grabbing part 8 is placed into the clamp 10 in a slightly opened state in the lathe through the mechanical arm 6, so that the end face of the stepped ring groove 2 of the die adjusting screw 1 is abutted against the end face of the clamp 10. At this time, the finger cylinder releases the clamping jaw 15, so that the extrusion plate 17 has a forward pushing tendency under the elastic force of the elastic compensation component 18, and is automatically leveled by means of the shaking interval 51, so that the end face of the stepped ring groove 2 of the die adjusting screw 1 is completely leveled with the end face of the lathe fixture 10 perpendicular to the clamping face of the fixture 10. In this state, the control jig 10 is clamped, so that the coaxial accuracy between the workpiece and the jig 10 can be improved, and the machining error caused by the clamping deviation can be reduced. After the clamp 10 is clamped, the sixth shaft 7 of the mechanical arm 6 is removed from the first numerically controlled lathe 3, and the A-side metal machining of the new workpiece can be performed.
In the machining process of the first numerical control lathe 3, the mechanical arm 6 transfers the semi-finished workpiece taken out of the first numerical control lathe 3 to the reverser 11 for grabbing point switching. In the switching process, the mechanical arm 6 controls the end face of the side a of the die adjusting screw 1 to face downwards, and translates the smaller end of the side a into the placement hole 27 along the plate surface of the placement plate 26 by means of the slot 28 on the side of the placement plate 26, so that the end face of the stepped ring groove 2 on the side a can be abutted against the upper plate surface of the placement plate 26. Then, the second gripping portion 9 releases the a-side end of the die adjusting screw 1 so that the a-side end and the B-side end of the die adjusting screw 1 can be exposed below and above the object placing plate 26, respectively. At this time, the mechanical arm 6 grabs the die adjusting nut 1 on the object placing plate 26 from the inner hole 14 on the B side through the first grabbing portion 8, and in the grabbing process, under the bearing effect of the object placing plate 26, the extrusion plate 17 can overcome the elastic supporting force of the elastic compensation component 18 to compress, and after the three clamping jaws 15 of the first grabbing portion 8 clamp the workpiece, the extrusion plate 17 is kept in an extrusion state. After the B-side end of the die adjusting screw 1 is grasped, the die adjusting screw 1 is taken out from the placement hole 27, and the switching of the grasping points can be completed.
After the switching of the grabbing points is completed, the mechanical arm 6 can transfer the first grabbing part 8 grabbing the semi-finished workpiece and the empty second grabbing part 9 to the vicinity of the second numerically controlled lathe 4, and the machined workpiece in the second numerically controlled lathe 4 is removed through the second grabbing part 9. At this time, the mechanical arm 6 clamps the semi-finished workpiece grasped on the commutator 11 in the clamp 10 of the second numerically controlled lathe 4 through the first grasping portion 8 to perform the B-side metalworking of the die adjusting screw 1. During clamping, the coaxial precision between the workpiece and the clamp 10 is still improved by the leveling mechanism 16, so that machining errors caused by clamping deviation are reduced.
After the sixth shaft 7 of the mechanical arm 6 is withdrawn from the second numerically controlled lathe 4, the machined workpiece can be placed on the tray 50 of the discharging device 12 through the second grabbing portion 9 for output, so that the whole machining process of the workpiece is completed. The whole workstation can continuously run by repeating the steps, so that the processing efficiency and the safety are improved.
The above operation process can be implemented by means of a PLC built-in program or an equivalent analog circuit, which belongs to the common general knowledge in the art, and will not be described herein.
