Abstract
The utility model discloses a clamping device provided with an eccentric cam and aims to solve the problems that clamping devices are prone to slipping and unstable in clamping when being used for clamping workpieces in the prior art. The clamping device comprises a first base, a second base and a handle, wherein a boss and a positioning stop block are arranged on the first base, the inner side of the boss is provided with a side clamping surface capable of clamping one side surface of a workpiece and an upper clamping surface capable of clamping the upper surface of the workpiece, the eccentric cam matched with the side clamping surface and the upper clamping surface of the cam for clamping the workpiece is arranged on the second base, and the eccentric cam is connected with the handle. According to the clamping device, the positioning stop block is arranged on the first base, so that the workpiece can be positioned by the positioning stop block and be prevented from slipping when being clamped; and meanwhile, clamping of the workpiece comprises side clamping and upper clamping by the boss, another side clamping of the eccentric cam as well as positioning and clamping of the stop block, so that the clamping stability of the workpiece can be guaranteed.
Description
Technical field
The utility model relates to machine tools, is specifically related to a kind of clamping device with eccentric cam.
Background technology
Clamping device is widely used in manufacturing, as the punching press to workpiece, riveted joint, welding, paste or solidify etc. and in process, usually need the position relationship that keeps correct, clamping device has various reference surfaces or point, workpiece can accurately be located, and therefore clamping device is considered to requisite parts in processing industry.
Existing clamping device often has the following disadvantages: while fixing prismatic workpiece, easily occur skidding 1.; 2. clamping is unstable.
Utility model content
The utility model provides a kind of clamping device with eccentric cam, easily skids, clamps unsettled problem to solve the holding workpiece that existing clamping device exists.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
With the clamping device of eccentric cam, comprise the first pedestal, the second pedestal and handle, the first pedestal is provided with boss and position block, boss inner side have can holding workpiece side side holding face and upper clamping face that can holding workpiece upper surface, the second pedestal is provided with the eccentric cam that coordinates holding workpiece with boss side holding face and upper clamping face, and eccentric cam is connected with handle.
This clamping device operation principle is as follows:
Rotate eccentric cam by handle, the distance of the side holding face of eccentric cam and boss is increased gradually, can unclamp workpiece; Opposite spin eccentric cam, dwindles the distance of eccentric cam and boss side holding face gradually, until eccentric cam props up workpiece, and now clamping work pieces.
Because this clamping device is provided with position block on the first pedestal, when holding workpiece, position block can be located workpiece, and prevents that workpiece from skidding; The clamping face of workpiece has been comprised to the side holding of boss and top clamping simultaneously, another side holding of eccentric cam, the location of block and clamping, therefore can ensure the stability of piece-holder.
Further, described eccentric cam is circumferentially provided with screw thread.When eccentric cam circumferentially arranges screw thread and can further prevent from clamping, workpiece skids.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model with the clamping device embodiment of eccentric cam.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The clamping device with eccentric cam as shown in Figure 1, comprise the first pedestal 1, the second pedestal 2, boss 3, eccentric cam 4 and handle 5, boss 3 and position block 6 are set on the first pedestal 1, boss 3 inner sides have can holding workpiece 7 sides side holding face 31 and upper clamping face 32 that can holding workpiece 7 upper surfaces, the eccentric cam 4 that coordinates holding workpiece 7 with boss 3 side holding faces 31 and upper clamping face 32 is set on the second pedestal 2, eccentric cam 4 is circumferentially provided with screw thread, and eccentric cam 4 is connected with handle 5.
This clamping device operation principle is as follows:
Rotate eccentric cam by handle, the distance of the side holding face of eccentric cam and boss is increased gradually, can unclamp workpiece; Opposite spin eccentric cam, dwindles the distance of eccentric cam and boss side holding face gradually, until eccentric cam props up workpiece, and now clamping work pieces.
