Description
Technical field
The utility model relates to a kind of machine tool component, is specifically related to a kind of fastening clamping device.
Background technology
In mechanical processing process, usually need first workpiece to be fixed by clamping device, make workpiece obtain the tram with respect to lathe and cutter, then workpiece is processed.By clamping device, workpiece is fixed, because the positional precision of workpiece is ensured by clamping device, can not be subject to the impact of workman's technical merit, so Workpiece Machining Accuracy is high and stable, and then the rate of reducing the number of rejects and seconds, ensured the quality of product; Because clamping device can make workpiece location and clamping rapidly, reduce significantly unproductive time again, improved production efficiency.So both can ensure mechanical processing quality, and enhance productivity, reduce labor intensity, can reduce again the excessive demand to workman's technology.Because processing needs, some workpiece will fix by hand actuable clamping device conventionally.
But workpiece is due to self problem of materials, the clamping force difference that some workpiece needs.In prior art, hand actuable clamping device cannot regulate clamping force size fast, easily.
Utility model content
The technical problems to be solved in the utility model comprises: in prior art, hand actuable clamping device cannot regulate fast, easily and clamp big or small shortcoming.
In order to solve the problems of the technologies described above, the utility model provides a kind of fastening clamping device, comprises pedestal, pull bar and adjusting rod, and described pedestal is revolving body, the geometric center of pedestal end face is provided with through hole, and pedestal side is also provided with the pilot hole intersecting vertically with through hole; Described pull bar one end is provided with the round boss coaxial with it, round boss diameter be greater than pull bar diameter and with pull bar for removably connecting, pull bar middle part is radially provided with square through hole, the pull bar other end penetrates in through hole; Described square through hole two side is parallel to each other, and its bottom surface tilts along through hole center line; Described adjusting rod is long strip type, on adjusting rod one side, be provided with the inclined-plane identical with square through hole bottom surface inclination angle, adjusting rod one end is through pilot hole and square through hole, the bottom surface of its inclined-plane and square through hole is offseted, the other end is fixedly connected with screw rod, and external thread of screw matches with the internal thread of regulating handle; Described regulating handle external diameter is greater than pilot hole diameter.
Adopt the fastening clamping device of such scheme, drive screw rod by rotation regulating handle, adjusting rod is outwards moved along pilot hole, and then make the bottom surface of inclined-plane compressing square through hole, pull bar is moved down.Now, round boss is by Work-sheet pressing.By rotation regulating handle, can make workpiece be subject to the clamping force of different sizes.
As preferred version, described pedestal upper surface geometric center is provided with boss, and boss and pedestal are structure as a whole.Adopt after such structure, because the end face contacting with instrument needs fine finishining, so only need the boss that working (finishing) area is less, and then cut down finished cost.
As preferred version, in described through hole, be provided with the spring for tie-strut.Spring, to one, pull bar thrust upwards, ensures that the bottom surface of inclined-plane and square through hole offsets in the time that clamping device is not worked, and prevents that adjusting rod from coming off.
As preferred version, described round boss lower end is also provided with the plate for increasing workpiece contact area.In the time of the larger workpiece of clamping face area, can increase with plate the lifting surface area of workpiece.
As preferred version, described regulating handle is T shape.Regulating handle adopts T shape structure, conveniently regulating handle is rotated.
Brief description of the drawings
Fig. 1 is the structural representation of the fastening clamping device embodiment of the utility model.
In figure, 1 is round boss, and 2 is square through hole, and 3 is adjusting rod, and 4 is pedestal, and 5 is regulating handle, and 6 is through hole, and 7 is spring, and 8 is pull bar, and 9 is pilot hole, and 10 is inclined-plane, and 11 is boss, and 12 is workpiece.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are described in further detail:
Fastening clamping device as shown in Figure 1, comprises pedestal 4, pull bar 8 and adjusting rod 3, and described pedestal 4 is revolving body, and the geometric center of pedestal 4 end faces is provided with boss 11, and boss 11 is provided with through hole 6; Pedestal 4 sides are also provided with the pilot hole 9 intersecting vertically with through hole 6.Described pull bar 8 one end are provided with the round boss coaxial with it 1, and round boss 1 diameter is greater than pull bar 8 diameters and is threaded connection with pull bar 8, and pull bar 8 middle parts are radially provided with square through hole 2; Pull bar 8 other ends penetrate in through hole 6, offset with the spring 7 in through hole 6.Described square through hole 2 two sides are parallel to each other, and its bottom surface tilts along through hole 6 center lines.Adjusting rod 3 is long strip type, is provided with the inclined-plane 10 identical with square through hole 2 bottom surface inclinations angle on adjusting rod 3 one sides; Adjusting rod 3 one end, through pilot hole 9 and square through hole 2, offset its inclined-plane 10 and the bottom surface of square through hole 2, and the other end is fixedly connected with screw rod, and external thread of screw matches with the internal thread of T shape regulating handle 5.Described regulating handle 5 external diameters are greater than pilot hole 9 diameters.
When use, first round boss 1 is taken off, the workpiece 12 that has centre bore is enclosed within on pull bar 8, round boss 1 is installed.Rotate T-shaped regulating handle 5, adjusting rod 3 is outwards moved along pilot hole 9, and then make inclined-plane 10 oppress the bottom surface of square through hole 2, pull bar 8 is moved down.Now, round boss 1 compresses workpiece 12.By rotation regulating handle 5, make workpiece 12 be subject to more suitable clamping force.
After workpiece 12 machines, the T-shaped regulating handle 5 of opposite spin, removes the power of oppressing square through hole 2 bottom surfaces, by the elastic force of spring 7, pull bar 8 is upwards promoted, and takes off after round boss 1, then workpiece 12 is taken off, and finally round boss 1 is installed.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
