Abstract

The invention relates to a fixture for broaching a thin-walled annular workpiece, which is used for clamping the annular workpiece so that a tool can broach the inner wall surface of the annular workpiece. There are two clamping pads, which are also annular correspondingly, located on the inner side of the tire mold, and are arranged at intervals in the thickness direction of the tire mold, so as to define an annular assembly cavity with an opening facing inward together with the inner wall of the tire mold. The annular workpiece is assembled in the annular assembly cavity. The tooling fixture can wrap the upper and lower end surfaces and the outer surface of the annular workpiece, so as to realize the firm clamping of the annular workpiece, which effectively avoids the deformation problem of the annular workpiece during the broaching process, reduces the scrap rate, and saves money. Cost of production. In the preferred solution, the two auxiliary clamping pads are made of free-cutting materials, which have a good buffering protection effect on the knife, and effectively improve the service life of the broach. It also relates to a broaching workbench and a broaching method.

Description

technical field [0001] The invention relates to the technical field of broaching machines, in particular to a tooling fixture for broaching thin-walled annular workpieces, a broaching workbench and a broaching method. Background technique [0002] Aviation parts such as disk workpieces (such as turbine disks) or some annular thin-walled workpieces have special requirements such as high temperature resistance and corrosion resistance. processed material. The internal mortise and groove of annular thin-walled workpieces on aircraft engines are usually processed by traditional techniques such as slotting, planing and milling. However, slotting, planing and milling are all single-tooth and single-edge cutting, and the tools are easy to use. Wear and tear, tool loss is large, and there are frequent impacts on the workpiece, and the toughness of the workpiece is very strong, which results in a low pass rate of the workpiece. [0003] Because the annular thin-walled workpiece its...
