Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0021] like figure 1 , figure 2 As shown, the measuring tool used in the present invention consists of a base plate 1, a positioning shaft 2, a first support block 3, a bushing 4, a positioning pin 5, a second support block 6, a gauge block 7, a handle 8, a top cover 13, a spring 14 and a manipulation Handle 15 etc. constitute. Wherein, the bottom plate 1 is a rectangular flat plate structure, and a positioning shaft 2 is arranged in the middle of the bottom plate 1. The positioning shaft 2 is perpendicular to the bottom plate 1. The top surface of the positioning shaft 2 and the circumferential surface are transitioned through a tapered surface, and the lower end of the positioning shaft 2 extends Inserted into the bottom plate 1, the two are closely matched, and the annular boss 2a integrally formed on the lower part of the positioning shaft 2 is support...

Abstract

The invention discloses a test method for positions of gearshift swing lever wavy surface ball grooves of automobile gear box. The test method comprises the following steps: 1) sleeving a positioning shaft with a shaft bush of the gearshift swing lever; 2) releasing an operating handle, the right end of a positioning pin abutting against a first ball groove of the wavy surface; 3) manipulating a first measuring block to move leftward, if a ball head can be clamped in a clamping groove in the left end of the first measuring block, then the position of the first ball groove of the gearshift swing lever wavy surface meets the requirement; 4) enabling the positioning pin loosen the push of the gearshift swing lever, and making a second ball groove of the gearshift swing lever wavy surface face the positioning pin; 5) the right end of the positioning pin abutting against the second ball groove of the wavy surface; 6) manipulating a second measuring block to move leftward, if the ball head can be clamped in a clamping groove in the left end of the first measuring block, then determining that the position of the second ball groove of the gearshift swing lever wavy surface meets the requirement. The test method can be used for testing the positions of two ball grooves of gearshift swing lever wavy surface; the test procedure is simple, the test result is accurate and reliable, and the test efficiency is high.

Description

technical field [0001] The invention relates to a method for detecting the position of a ball groove on a waveform surface of a shift lever, which is used for detecting the position of the ball groove on the waveform surface of a shift lever of an automobile gearbox. 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. At present, various manufacturers have not specifically tested the position of the ball groove on the wave surface of the shift lever, which may easily lead to poor product quality control and affect the assembly accuracy of the shift lever, making it difficult to meet the requirements of consistent production. Contents of the invention [0003] The technical ...
