Abstract

The invention discloses a shift shaft assembly pulling head position accuracy testing fixture which relates to the technical field of process equipment manufacture. The shift shaft assembly pulling head position accuracy testing fixture comprises a base board which is provided with two V-shaped positioning blocks. The base board is provided with a spacing seat between the two V-shaped positioning blocks. The spacing seat is provided with an extending-out part. A spacing bolt which extends to a portion above the connecting line between the centers of the two V-shaped positioning blocks is equipped on the extending-out part in a penetrating manner. The base board is provided with an upper lever unit and a lower lever unit which detect the position accuracy of the shift shaft assembly pulling head between the spacing seat and the V-shaped positioning block. Compared with the prior art, the shift shaft assembly pulling head position accuracy testing fixture can settle a problem of large control cover jitter caused by position accuracy out-of-tolerance of an existing shift shaft assembly pulling head.

Description

technical field [0001] The invention relates to the technical field of process equipment manufacturing, in particular to a position checking tool for a shift head of an automobile shift shaft assembly. Background technique [0002] NVH is the English abbreviation of Noise, Vibration and Harshness. It is a comprehensive problem to measure the quality of automobile manufacturing. The failure problem of 3 is related to the NVH problem of the vehicle. The gear selection shaft assembly is an important part of the automobile transmission, which has a great influence on the handling comfort of the whole vehicle; usually, there is a manual transmission, and the gear selection of the manual transmission is toggled by a block on the fork shaft. It is completed by the shift head arranged on the gear selection shaft assembly. At present, through testing, the NVH noise value of the manual transmission is large. Among them, the vibration of the control cover on the manual transmission h...
