Reliable and Efficient Fixtures

Abstract

The invention discloses a reliable efficient fixture which is characterized by comprising a positioning compression cam, a press plate moving cam, a moving positioning assembly, a positioning block, acam mounting frame, a press plate assembly and an operating handle, wherein the press plate moving cam is rotationally arranged on the cam mounting frame; the rotating axis of the press plate movingcam is set along the up-down direction; the moving positioning assembly comprises a moving mounting seat and two floating press heads; the floating press heads are symmetrically arranged at two ends of the U-shaped moving mounting seat and both hinged onto the moving mounting seat; the press plate moving cam is driven by the operating handle to rotate; the press plate assembly is driven to move left and right; the positioning compression cam and the press plate moving cam are in transmission connection with each other; the moving mounting seat of the moving positioning assembly is driven by the positioning compression cam to move left and right; and then a workpiece is compressed and positioned in the positioning blocks through the floating press heads. Consequently, the press plate assembly can be driven by the positioning compression cam to compress and fix the workpiece from above.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a reliable and efficient fixture for clamping and fixing workpieces with right angles. Background technique [0002] Parts with regular shapes (such as cubes, cuboids and cylinders, etc.) are widely used in engineering practice. The clamping scheme is simple and reliable, and has wide application. If the workpiece is manually clamped, the workpiece must be placed on the workbench so that the right-angled side of the workpiece is in reliable contact with the right-angled side of the fixed positioning block (a certain force is applied by hand), and the hand cannot be loosened at this time (the pressure plate may be pressed tightly). It will cause the workpiece to move, causing the workpiece to be processed and scrapped), use the other hand to move the pressure plate to the top of the workpiece, and then use a wrench to compress the workpiece. The entire clamping process requires...

AI Technical Summary

Problems solved by technology

The entire clamping process requires three steps. The labor intensity of the workers is high, the clamping efficiency is low, and automatic production cannot be realized, and clamping errors are prone to occur and the workpiece is scrapped.

There are also some automatic positioning and clamping equipment, but these automatic positioning and clamping equipment are usually completed by two sets of independent mechanisms, the upper plane clamping mechanism and the positioning device, which require two sets of power sources to drive, which wastes energy and takes up a lot of space. In the case of limited clamping space, the layout is difficult and cannot be completed, and the two independent mechanisms will also complicate the control system of the automatic production line and increase the failure rate, which will also cause waste of resources
