Embodiment 1

[0027] Such as figure 1 and figure 2 The shown double-groove type cam-driven pair space clamp includes a clamping assembly, a supporting assembly and a driving device 1, and the driving device 1 and the clamping assembly are arranged on the supporting assembly;

[0028] The clamping assembly includes a double-slotted cam 4 and multiple sets of levers. The output shaft of the drive device 1 is vertically upward and the double-slotted cam 4 is fixed on the sleeve. The double-slotted cam 4 is slidably connected to one end of the lever group. ;

[0029] The double-line groove type cam 4 comprises a special-shaped disk body, and a surface of the disk body is provided with a groove body one, and the groove body one is a closed groove provided along the outer contour of the disk body, and the inner side of the groove body one is also provided with a plurality of grooves. The second groove body is symmetrically arranged on the disk body, the second groove body is parallel to the fi...

Embodiment 2

[0035] As a further optimization scheme of Embodiment 1, in order to make the sliding between lever one 6 and groove body two, lever two 7 and groove body one smoother, a double-line groove type cam 4 is provided at the end of lever one 6 and lever two 7 close to the double-slotted cam 4 The roller 3 is clamped and limited in the tank body 1 and the tank body 2 respectively.

Embodiment 3

[0037] As a further optimization scheme of embodiment 1, in order to improve the adaptability of lever one 6 and lever two 7 to the shape of the workpiece 12, a movable pressing block is provided at the end of lever one 6 and lever two 7 away from the double groove type cam 4 10.

[0038] The movable briquetting block 10 is respectively hinged at the end of the lever one 6 and the lever two 7, and the hinged structure can allow the movable briquetting block 10 to rotate in a certain range along the hinge axis, so that the adaptability of the movable briquetting block 10 to the surface of the workpiece 12 can be improved. Significantly improved, without having to be limited to a specific workpiece shape or regular shape.

Abstract

The invention discloses a double wiring duct type cam drive pair space clamp, and belongs to the technical field of clamps used for machining. The double wiring duct type cam drive pair space clamp comprises a clamping assembly, a supporting assembly and a stepping motor. The clamping assembly comprises a double wiring duct type cam and multiple lever sets. An output shaft of the drive device vertically faces upwards, the double wiring duct type cam is installed on the output shaft in a sleeving manner and is fixed to the output shaft, and the double wiring duct type cam is connected with oneends of the lever sets in a sliding manner. According to the double wiring duct type cam drive pair space clamp, the double wiring duct type cam is driven through the stepping motor, four rolling wheel grooves are formed in each spiral line of a cam pair and drive clamping levers correspondingly, and the top face and the side faces of a workpiece can be clamped. Movable pressing blocks on connection rods can rotate around rotating shafts of the connection rods, and therefore when the size and surface planeness of the workpiece are changed, the pressing blocks can make sufficient contact with the surface of the workpiece, and the clamping force distribution can be uniform. The double wiring duct type cam drive pair space clamp is low in cost, simple in structure, convenient to install, compact in structure, capable of achieving space multi-point clamping of different sizes of workpieces with uneven pressed faces and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of fixtures for mechanical processing, and in particular relates to a double-slot type cam-driven pair space fixture. Background technique [0002] In mechanical processing, the use of fixtures to assist the clamping of workpieces is very common. For the processing of small batches of workpieces, the effect of using fixtures is not very obvious. However, for the processing of large batches of workpieces, the effect is significant, that is, it can greatly reduce the labor of workers. The labor intensity can be greatly improved, and the processing efficiency of the workpiece can be greatly improved, and the economic cost of the workpiece can be reduced. [0003] At present, the clamping mechanism used in mechanical processing can only achieve single-sided clamping. Even if it can achieve multi-point clamping in space after barely compounding, the structure is too complicated. [0004] In view of the above rea...
