A multi-purpose fixture for manufacturing engine drive shafts

Abstract

The invention discloses a multipurpose clamp for manufacturing an engine transmission shaft. The multipurpose clamp comprises a positioning clamp (2), a pressing plate (3), a Mohs cone connecting block (4), a first lock screw (5) and a second lock screw (6). The end, with an opening type horn hole structure, of a machined part (1) is put into a positioning groove body of the positioning clamp (2), one end of the Mohs cone connecting block (4) is fixedly connected with the positioning clamp (2) through the first lock screw (5), and the part, with a cone, of the Mohs cone connecting block (4) can be directly installed on a main shaft of an outer spline milling machine tool with a Mohs inner cone, and a main shaft of a numerical control outer circle grinding machine. The second lock screw (6) is used for arranging the part (1) into the positioning clamp (2) and then pressing the pressing plate (3), and the pressing plate (3) can press the part (1). According to the multipurpose clamp for manufacturing the engine transmission shaft, the machining quality of the shaft type part products can be improved, the qualification rate required technically can be increased, and the accuracy of machining sizes can be improved; and the one-time presenting qualification rate of the parts is ensured, time and labor are saved, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a clamp for an aero-engine transmission shaft. Background technique [0002] As the core element of the engine, the transmission shaft is one of the components with high load, high strength and effective transmission of power. Its structural characteristics are mainly composed of thin walls and slender shapes. The outer open horn hole structure increases the difficulty of processing and the amount of deformation to a greater extent. How to solve the clamping deformation during processing has become one of the key issues for shaft parts. [0003] In the aviation industry, with the improvement of design capabilities and manufacturing capabilities, the integration of engine parts is getting higher and higher, the design of parts tends to be integrated, lightweight, and sophisticated, and the surface structure is becoming more and more complex. This type of shaft wor...

AI Technical Summary

Problems solved by technology

Since the part belongs to the slender shaft type, the rigidity of the body structure is poor, and many uncertain factors such as axial bending deformation, dimensional accuracy and technical conditions, and wall thickness difference are difficult to guarantee during the processing process.
