Abstract
The utility model discloses a machine tool component, and particularly relates to an adjustable clamping device. The adjustable clamping device comprises two clamping plates, a limiting block and a connecting rod, wherein the limiting block is arranged between the two clamping plates, guide blocks are arranged at the two ends of the limiting block respectively, the clamping plates are respectively of a cuboid shape, guide holes corresponding to the guide blocks are formed in the clamping plates respectively so that the clamping plates can slide along the guide blocks, through holes are formed in the lower ends of the clamping plates and are in the same direction of guide holes, a clamping adjusting nut is arranged at one end of the connecting rod, and is connected with the connecting rod through threads, the other end of the connecting rod penetrates through the through holes in the two clamping plates, and is hinged to an opening and closing cam, and the distance between the two clamping plates is controlled to be changed through rotation of the opening and closing cam. By the adoption of the structure, the magnitude of clamping force borne by a workpiece can be adjusted by rotating the clamping adjusting nut.
Description
Technical field
The utility model relates to a kind of machine tool component, is specifically related to a kind of adjustable 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 guaranteed 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, guaranteed 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 guarantee 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, and some workpiece needs larger clamping force, and some workpiece needs lighter clamping force.Hand actuable clamping device of the prior art, cannot regulate the size of clamping force.
Utility model content
The technical problems to be solved in the utility model comprises: hand actuable clamping device of the prior art, cannot regulate the shortcoming of clamping force size.
In order to solve the problems of the technologies described above, the utility model provides a kind of adjustable clamping device, comprises two clamping plate, limited block and connecting rods, and described limited block is between two clamping plate, and limited block two ends are provided with guide pad; Described clamping plate are cuboid, are provided with and the corresponding pilot hole of guide pad on clamping plate, and clamping plate can be slided along guide pad, and clamping plate lower end is provided with and the unidirectional through hole of pilot hole; Described connecting rod one end is provided with clamping adjusting nut, clamps adjusting nut and connecting rod and is threaded connection, and the connecting rod other end passes the through hole on two clamping plate, and hinged with make and break cam, rotates by make and break cam, controls the variation of two clamping plate spacings.
Adopt the adjustable clamping device of such scheme, regulate two distances between clamping plate by the rotation of controlling make and break cam, and then make two clamping plate by Workpiece clamping.Clamp adjusting nut by rotation again, the distance between two clamping plate is finely tuned, regulate the size of the suffered clamping force of workpiece.
As preferred version, described connecting rod periphery is provided with fastening spring, and fastening spring is between two clamping plate.Adopt after such structure, in the time that clamping plate unclamp the workpiece of having processed, the elastic force of fastening spring can make pressing plate automatically separate, and does not need manually to separate pressing plate, easy to operate.
As preferred version, in described make and break cam, be provided with handle.Can drive very easily make and break cam to rotate by handle.
As preferred version, described clamping plate upper end is provided with the slipmat for increasing frictional force between workpiece and clamping plate.Slipmat not only can increase frictional force between large workpiece and clamping plate, can also prevent that surface of the work from scratching.
Accompanying drawing explanation
Fig. 1 is the structural representation of the adjustable clamping device embodiment of the utility model.
In figure, 1 is clamping plate, and 2 is guide pad, and 3 for clamping adjusting nut, and 4 is fastening spring, and 5 is make and break cam, and 6 is connecting rod, and 7 is handle, and 8 is axle, and 9 is limited block, and 10 is workpiece.
the specific embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are described in further detail:
Adjustable clamping device as shown in Figure 1, comprises two clamping plate 1, limited block 9 and connecting rod 6, and described limited block 9 is between two clamping plate 1, and limited block 9 two ends are provided with guide pad 2.Described clamping plate 1 are cuboid, and one end that clamping plate 1 contact with workpiece 10 is provided with pressure sensitive contact, are provided with and the corresponding pilot hole of guide pad 2 on clamping plate 1, and clamping plate 1 can be slided along guide pad 2; Clamping plate 1 upper end is provided with the slipmat for increasing frictional force between workpiece 10 and clamping plate 1, and clamping plate 1 lower end is provided with and the unidirectional through hole of pilot hole; Between two clamping plate 1, be also provided with spring.Described connecting rod 6 one end are provided with and clamp adjusting nut 3, clamp adjusting nut 3 and be threaded connection with connecting rod 6, connecting rod 6 other ends pass through hole and the fastening spring 4 on two clamping plate 1, and hinged with make and break cam 5, rotate by make and break cam 5, control the variation of two clamping plate 1 spacings.
When use, workpiece 10 is placed between two clamping plate 1, one end of workpiece 10 is against limited block 9 surfaces.Rotary opening closing cam 5, reduces the distance between two clamping plate 1, and clamping work pieces 10, clamps adjusting nut 3 by rotation, and the distance between two clamping plate 1 is finely tuned, and regulates the size of the suffered clamping force of workpiece 10.If workpiece 10 pressures are excessive, pressure sensitive contact can start alarming device, reminds operating personnel to reduce thrust.Can prevent that like this thrust is excessive to be damaged workpiece 10 because being subject to.Treat that workpiece 10 machines, rotary opening closing cam 5, by the elastic force of fastening spring 4, increases the distance between two clamping plate 1, and workpiece 10 is taken out.
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.
