Abstract

The utility model discloses a workpiece clamping device, and aims to solve the problem that the conventional clamping device has a complex structure and clamps a cylindrical workpiece unstably. The clamping device comprises a clamping platform, an adjustment eccentric shaft and a clamping cam, wherein a groove, of which the inner wall is a cylindrical curved surface, is formed in the surface of the clamping platform; baffles are respectively arranged on the two opposite sides of the clamping platform; a boss with a through hole is arranged at the upper part of each baffle; the adjustment eccentric shaft penetrates through the through holes; the clamping cam is arranged on the adjustment eccentric shaft. The clamping device only comprises the clamping platform, the baffles, the adjustment eccentric shaft and the clamping cam, so that the structure is relatively simple and the practicability is high; the inner wall of the groove in the surface of the clamping platform has the cylindrical curved surface, so that the groove can be matched with the cylindrical surface of the cylindrical workpiece; the cylindrical workpiece is placed in the groove and is clamped by the clamping cam, so that the clamping is more stable and the clamping effect is better.

Description

Workpiece clamping device
Technical field
The utility model relates to machine tools, is specifically related to a kind of Workpiece clamping device.
Background technology
Clamping device is widely used in manufacturing, as the punching press to workpiece, riveted joint, welding, paste or solidify etc., usually needs the position relationship that holding workpiece is correct.Clamping device has various datum levels or point, and workpiece can accurately be located, and therefore clamping device is considered to requisite parts in processing industry.
At present, the fixture of holding workpiece often has the following disadvantages: 1. complex structure, poor practicability; 2. for cylindrical work, owing to there is no the clamping device that cylindrical surface coordinates with it, therefore unstable to the clamping of cylindrical work, effect is bad.
Utility model content
The utility model provides a kind of Workpiece clamping device, to solve existing clamping device complex structure, cylindrical work is clamped to unsettled problem.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
Workpiece clamping device, comprise clamping platform, adjust eccentric shaft and clamp cam, clamping platform table top has the groove that inwall is Cylinder Surface, the both sides that clamping platform is relative are respectively equipped with baffle plate, baffle plate top is equipped with the boss with through hole, adjust eccentric shaft and be arranged in through hole, adjust on eccentric shaft clamping cam is set.
This clamping device operation principle is as follows: rotate and adjust eccentric shaft, adjusting eccentric shaft drives clamping cam to rotate, make the cam that clamps cam forward the position of clamping platform table top groove dorsad to, cylindrical work is inserted in the groove of clamping platform table top, then rotate backward adjustment eccentric shaft, make the cam that clamps cam forward the position relative with clamping platform table top groove to, clamp cylinders shape workpiece.
The beneficial effects of the utility model: first, this clamping device only comprises clamping platform, baffle plate, adjustment eccentric shaft and clamping cam, and structure is simpler, practical; Secondly, because the groove inwall of clamping platform table top has Cylinder Surface, can match with the periphery of cylindrical work, cylindrical work is inserted in groove and is clamped via clamping cam, clamp more stablely, clamps better effects if.
Further, adjust eccentric shaft and boss and pass through spline joint.Spline joint have guidance quality good, can bear larger power, improve the service life of this clamping device.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model Workpiece clamping device embodiment;
Fig. 2 is the structural representation of adjusting eccentric shaft in Fig. 1 embodiment.
In Fig. 1, arrow represents to clamp the rotation direction of cam.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Workpiece clamping device as shown in Figure 1, comprise clamping platform 1, baffle plate 2, adjust eccentric shaft 3 and clamp cam 4, clamping platform 1 table top has the groove 11 that inwall is Cylinder Surface, the both sides that clamping platform 1 is relative arrange respectively baffle plate 2, baffle plate 2 tops are equipped with the boss 21 with through hole, adjust eccentric shaft 3 and be arranged in through hole, adjust on eccentric shaft 3 and arrange and clamp cam 4, workpiece 5 is placed in the groove 11 of clamping platform 1 table top.
As shown in Figure 2, adjust eccentric shaft 3 and comprise the handle 32, the eccentric shaft 31 at middle part and the spline structure 33 of the other end that are arranged at end, adjust eccentric shaft 3 and pass through spline joint with boss 21.
This clamping device operation principle is as follows: rotate and adjust eccentric shaft, adjusting eccentric shaft drives clamping cam to rotate, make the cam that clamps cam forward the position of clamping platform table top groove dorsad to, cylindrical work is inserted in the groove of clamping platform table top, then rotate backward adjustment eccentric shaft, make the cam that clamps cam forward the position relative with clamping platform table top groove to, clamp cylinders shape workpiece.
