Processing clamp of thin-wall rotation work piece

Abstract

The invention provides a processing clamp of a thin-wall rotation work piece. The processing clamp comprises a baseplate, a supporting body installed on the baseplate and multiple fixation pivots installed on the supporting body. The processing clamp also comprises a movable pivot and a limiting shaft installed on the supporting body, an adjustment block which is installed on the limiting shaft and drives the movable pivot to move horizontally back and forth, as well as an adjustment thread rod which is inserted in the supporting body and matched with the adjustment block, wherein a limiting hole used for passing of the limiting shaft is formed in the adjustment block; and the movable pivot, the limiting shaft and the adjustment thread rod are installed on the supporting body in a mutually perpendicular manner. The processing clamp provided by the invention has the advantages that the structure is simple; processing and manufacture are convenient; the processing clamp is used as machine tool processing equipment, has high practicability, is operated conveniently and rapidly and has high efficiency; and the problems that clamping deformation takes place to the thin-wall rotation work piece, and position accuracy of the processed work piece cannot be guaranteed when a positioning standard of two times of clamping is not accurate, and the like can be effectively solved.

Description

technical field [0001] The invention relates to the field of clamps, in particular to a processing clamp for a thin-walled rotary workpiece. Background technique [0002] The existing processing of thin-walled rotary workpieces depends on the type, shape, and size of the blank. Generally, there are two main technical solutions: [0003] 1. The blank is formed by casting, forging, rolling, etc. This type of blank has a large external dimension and unstable external dimensions, and there is no special fixture. Generally, it is fixed by the general fixtures of machine tools such as three- and four-jaw chucks and pressure plates. One end of the workpiece is machined at the other end. [0004] 2. The blank is formed by extrusion, precision casting, etc. The shape of this type of blank is small and the change of shape is small. The positioning of the workpiece in the two clampings is accurate. Generally, a mandrel, an expansion sleeve or a special fixture is used. [0005] There...

AI Technical Summary

Problems solved by technology

[0006] The defect of technical solution 1 is: the workpiece needs to be corrected when clamping the workpiece, which is time-consuming and laborious, the positioning of the two clampings is not accurate, the position accuracy of the workpiece cannot be guaranteed, the workpiece is easily deformed when the clamping force is applied, the processing quality of the workpiece cannot be guaranteed, and the production efficiency is low.

[0007] The defect of technical solution 2 is: one-time clamping cannot realize multi-station processing, it is suitable for batch assembly line processing and production, the number of machine tools and equipment is large, the production efficiency is low, and the cost investment is large
