Automobile shifting fork automatic manufacturing combined machine tool

Abstract

The invention relates to an automobile shifting fork automatic manufacturing combined machine tool, and mainly aims to solve the problems of difficulty in making a form and location tolerance between positioning reference surfaces as well as between the positioning reference surfaces and positioning reference holes be up to a design standard, low machining efficiency, high labor intensity, difficulty in controlling the product quality and high machining cost in the conventional automobile shifting forks. The automobile shifting fork automatic manufacturing combined machine tool is characterized in that a first upper plane milling power head (3), a second upper plane milling power head (4), a side plane milling power head (5), a round table end face milling power head (6), a drilling power head (7) and a reaming power head (8) are arranged in sequence from left to right above a bed body (1). The positioning reference surfaces and the positioning reference holes of an automobile shifting fork are machined through one-time clamping, so that the form and location tolerance between the positioning reference surfaces as well as between the positioning reference surfaces and the positioning reference holes of the automobile shifting fork are effectively ensured, the production efficiency is increased, the product quality is enhanced, a high degree of automation is achieved, and the demands of a large-scale automatic production line are met.

Description

technical field [0001] The invention relates to a machining equipment for auto parts, in particular to an auto-processing combined machine tool for an auto shift fork. Background technique [0002] The automobile industry is the pillar industry of my country's national economy. With the development of my country's economy, people's living conditions are getting better and better. In recent years, the number of cars per capita in my country has increased rapidly. The tasks of domestic auto parts enterprises are becoming more and more onerous, and mass production is the production characteristic of auto parts enterprises. The car shift fork is a part in the car gearbox, which is used to toggle the sliding gear to change the transmission ratio, and then realize the operation of up and down. Chinese invention patent CN201410175041.4 discloses an automatic machine tool for machining an automobile shift fork, which is used for one-time processing of the inner surface of the fork ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the shape and position tolerance between the positioning reference planes of the existing automobile shift fork and between the positioning reference plane and the positioning reference hole are difficult to meet the design standards, the processing efficiency is low, the labor intensity of the workers is high, the product quality is not easy to control and the processing cost High problem, the present invention provides an automatic processing combination machine tool for automobile shift fork, the automatic processing combination machine tool for automobile shift fork adopts positioning V-shaped block, pneumatic lift deflection fixture, pneumatic manipulator and numerical control sliding table, etc. The positioning reference plane and positioning reference hole of the casting blank of the automobile shift fork effectively guarantee the shape and position tolerance between each positioning reference plane of the automobile shift fork and between the positioning reference plane and the positioning reference hole, which improves the production efficiency and product quality , reduced processing costs, high degree of automation, reduced labor intensity of workers, and met the needs of large-volume automated production lines
