Broaching tooling for turbine discs and disc parts

Abstract

The invention relates to the technical field of numerical control machine tools, and specifically discloses a broaching tooling for turbine discs and disc parts, including a mounting seat (100), on which an indexing plate (200) is arranged, and the The rotating disc (202) of the indexing disc is provided with a supporting disc (300), the gland disc (400) is detachably connected to the supporting disc, and the housing (201) of the said indexing disc is provided with one or more A first hydraulic clamping device (500), the free clamping end of the first hydraulic clamping device corresponds to the outer disc surface of the gland disc. The invention has the characteristics of simple structure, high processing efficiency, simple processing process, time-saving and labor-saving, high processing precision, good stability, guaranteed processing quality and easy replacement of workpieces.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a broaching tooling for turbine discs and disc parts. Background technique [0002] The broaching process is a type of machining operation in the machinery industry. It is a cutting process that uses a broaching machine to process internal and external surfaces. When the broach is used as the cutting tool for cutting, when the broach moves in a straight line relative to the workpiece, the machining allowance of the workpiece is cut off sequentially by the teeth on the broach that increase in size tooth by tooth. It is mostly used to process non-closed surfaces, such as planes, forming Surfaces, grooves, mortises, blade tenons and external gears, etc., are especially suitable for processing relatively large planes and composite surfaces in mass production, such as the mortise and groove of aero-engine turbine disk workpieces are often formed by broaching ....

AI Technical Summary

Problems solved by technology

Milling with a multi-axis machining center requires high equipment and low processing efficiency; broaching with a CNC broaching machine, during the broaching process, because the broach can only move in a straight line, the workpiece needs to be kept at a certain position and tenon The distribution of grooves on the turbine disk is evenly distributed on the circumference. Therefore, after broaching a tenon groove, it needs to be rotated at a certain angle before broaching. The processing process is very cumbersome and time-consuming.

[0004] Therefore, the existing broaching processing of the mortise and groove on the turbine disk and disk parts has the problems of high equipment requirements, low processing efficiency, cumbersome processing, time-consuming and labor-intensive processing, low processing accuracy and poor processing quality.
