Detection method for waveform surface and ball head position of shift swing rod of automobile gearbox

Abstract

The invention discloses a detection method for a waveform surface and a ball head position of a shift swing rod of an automobile gearbox. The method comprises the steps: 1) rotating a control handle so that a positioning pin moves leftwards and a spring is compressed; 2) sleeving a positioning shaft with a spindle sleeve of a shift swing rod so that the spindle sleeve is supported by an annular boss of the positioning shaft, making a waveform surface of the shift swing rod face to the left, and making a ball head face to the right; 3) loosening the control handle and enabling the positioning pin to move rightwards under the resilience of the spring till the right end of the positioning pin is pressed against a middle groove in the waveform surface; and 4) enabling the positioning pin to stay in a pressed state without moving by means of the elastic force of the spring, operating a measuring block and making the block move leftwards, and verifying that the waveform surface and the ball head position of the shift swing rod accord with requirements if a clamping groove in the left end of the measuring block can just clamp the ball head. The detection method is easy, fast and labor-saving to operate, has fewer detection procedures, provides a true, accurate and reliable detection result, is high in detection efficiency, and ensures that the shift swing rod satisfies the requirement of production consistency.

Description

Technical field [0001] The invention relates to a method for detecting the position of the wave surface and the ball head of a shift pendulum rod, which is used for detecting the positions of the ball head and the wave face of an automobile shift pendulum rod. Background technique [0002] The shift lever is an important part of the automobile gearbox. Existing gear shift levers are generally steel forged parts, consisting of a shaft sleeve, a ball head, a foot, and a wave surface. The shaft sleeve is sleeved on the shaft through a central shaft hole, and is symmetrically opened in the middle of the shaft sleeve along the radial direction. There is a pin hole, and the pin and mother pin pass through the pin hole to fix the sleeve and the shaft. At present, various manufacturers have not specifically inspected the positions of the ball head and the wave surface of the shift lever, which easily leads to poor product quality control, and affects the assembly accuracy of the shift l...
