Abstract
The invention discloses a machine tool component and specifically 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 located between the two clamping plates, and guide blocks are arranged at the two ends of the limiting block; the clamping plates are cuboids, guide holes corresponding to the guide blocks are formed in the clamping plates so that the clamping plates are capable of sliding along the guide blocks, and through holes in the same direction with the guide holes are formed at the lower ends of the clamping plates; a clamping adjusting nut is arranged at one end of the connecting rod, and in threaded connection with the connecting rod, the other end of the connecting rod penetrates through the through holes in the two clamping plates and is hinged to an on-off cam, and the change of the distance between the two clamping plates is controlled due to the rotation of the on-off cam. With such a structure, the clamping adjusting nut is rotated so that the clamping force on a workpiece can be adjusted.
Description
Technical field
The present invention relates to a kind of machine tool component, be 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 unproductive time significantly again, improved production efficiency.So both can guarantee mechanical processing quality, and enhance productivity, reduce labor intensity, can reduce the excessive demand to workman's technology again.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.
Summary of the invention
The technical problem to be solved in the present invention 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 invention provides a kind of adjustable clamping device, comprise two clamping plate, limited block and connecting rods, 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, by make and break cam, rotates, and controls the variation of two clamping plate spacings.
Adopt the adjustable clamping device of such scheme, by controlling the rotation of make and break cam, regulate two distances between clamping plate, and then make two clamping plate by Workpiece clamping.By rotation, clamp adjusting nut 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, when 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.By handle, can drive very easily make and break cam to rotate.
As preferred version, described clamping plate upper end is provided with for increasing the slipmat of 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 present invention.
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 solution of the present invention is 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 for increasing the slipmat of 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, by make and break cam 5, rotate, control the variation of two clamping plate 1 spacings.
During 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 the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
