Automobile gearbox shift pendulum rod wavelike surface and ball head position detection mechanism

Abstract

The invention discloses an automobile gearbox shift pendulum rod wavelike surface and ball head position detection mechanism. A top cover is arranged on a first support block, the vertical plate of the top cover is on the left of the first support block, the left end of a positioning pin passes through the vertical plate of the top cover and is hinged to an operating handle, and the positioning pin is sleeved with a spring. A second support block is fixed on the right-end plate surface of a bottom plate, a measuring block is arranged in the second support block in a penetrating way, the measuring block is provided with a 'U'-shaped clamp slot in the left end, and the opening of the clamp slot directly faces the positioning pin. A positioning shaft is arranged between the positioning pin and the measuring block, the positioning shaft is perpendicular to the bottom plate, the lower end of the positioning shaft is fixed to the bottom plate, and an annular boss integrally formed by the lower part of the positioning shaft is supported by the bottom plate. The mechanism of the invention has the advantages of clever design, simple and compact structure, easy implementation, fewer parts, convenient assembly, and low cost. The detection operation is easy, quick and labor-saving, detection involves few working procedures, the detection result is true, accurate and reliable, and the detection efficiency is high. The mechanism can ensure that shift pendulum rods meet the requirement of production consistency.

Description

technical field [0001] The invention relates to a detection mechanism for a wave surface and a ball head position of a gear shift swing rod, which is used for detecting the positions of the ball head and the wave face of a gear shift swing rod 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 head and 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. Therefore, it is very necessary to design a set of...
