Method for detecting symmetry of ball head of shift swing rod

Abstract

The invention discloses a method for detecting symmetry of a ball head of a shift swing rod. A measuring tool comprises a base plate, a positioning shaft, a first supporting stand, a lining, a positioning pin, a second supporting stand, a measuring shaft, a handle, etc. The method comprises the following steps: 1) moving a shift swing rod to be above the base plate, and enabling a shaft hole in a spindle sleeve of the shift swing rod to be in alignment with the positioning shaft and a ball head of the shift swing rod to face rightwards; 2) moving the shift swing rod downwards so that the positioning shaft passes through the shaft hole in the spindle sleeve and a pin hole in the spindle sleeve is in alignment with a positioning hole in the positioning shaft; 3) pushing the positioning pin from the back to the front so that the front end of the positioning pin penetrates the pin hole in the spindle sleeve and the positioning hole in the positioning shaft; and 4) finally controlling the measuring shaft to move leftwards, and identifying that the symmetry of the ball head of the shift swing rod accords with requirements if a detection opening formed between two measuring blocks just can clamp the ball head. The measuring tool is simple and compact in structure, and is easy, fast and labor-saving to operate. An accurate and reliable detection result can be provided, and the detection efficiency is high.

Description

Technical field [0001] The invention relates to a method for detecting the symmetry of the ball head of a shift pendulum rod, which is used for detecting the symmetry of the ball head of an automobile shift pendulum rod relative to a pin hole. 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 tested the symmetry of the shift lever ball head, which is likely to cause poor product quality control, and affect the assembly accuracy of the shift lever, and it is difficult to meet the requireme...
