Machining and positioning mechanism for corrugated faces of automotive gear shift oscillating bars

Abstract

The invention discloses a machining and positioning mechanism for the corrugated faces of automotive gear shift oscillating bars. A connection rod is arranged between a guide column and a jacking oil cylinder and penetrates a guide seat. The base is provided with a positioning groove extending in the left-right direction. The positioning groove is located below the guide column. A front clamping strip and a rear clamping strip are arranged in the positioning groove, fixed to the base through bolts and arranged in parallel. The rear side of the guide column is provided with a limiting block in a long strip shape. The bottom face of the limiting block is attached to the top face of the base. The limiting block is fixed to the base through a row of bolts. The top of the front end face of the limiting block is integrally provided with a protruding edge extending in the left-right direction. According to the machining and positioning mechanism, the multiple gear shift oscillating bars are positioned precisely through cooperation of the connection rod and a positioning seat, the clamping firmness of the gear shift oscillating bars is good, and the machining efficiency and the machining accuracy of the corrugated faces of the gear shift oscillating bars are improved.

Description

technical field [0001] The invention relates to a wave surface processing and positioning mechanism of an automobile gear shift lever, which is used for clamping the gear shift lever to process the wave surface. Background technique [0002] The shift lever is an important part of the car gearbox. The existing shift lever is generally a steel forging, which is composed of a shaft sleeve, a ball head, a leg and a corrugated surface. There are pin holes, and the female and female pins are passed through the pin holes, so that the bushing and the shaft are fixed. The wave surface of the gearshift lever needs to be further processed on a milling machine, and the gearshift lever must be positioned on the milling machine with the aid of a specially made clamping device. The existing clamping device has a complex structure and a large volume, which is not only difficult to assemble, but also has high production costs, and the clamping operation is cumbersome, the clamping efficie...

Problems solved by technology

The existing clamping device has a complex structure and a large volume, which is not only difficult to assemble, but also has high production costs, and the clamping operation is cumbersome, the clamping efficiency is not high, and the clamping reliability is not guaranteed; at the same time, only one piece can be processed at a time Workpieces, the processing efficiency is extremely low, and the milling cutter is easy to wear. With the increase of the number of processed workpieces, the accuracy of the corrugated surface processed by subsequent milling will decrease, and the processing quality will decrease.
