Problems solved by technology

[0002] An automobile connecting rod, comprising a large connecting rod end and a small connecting rod end. A shaft positioning groove is arranged on the inner side of the shaft hole of the large connecting rod end. It is difficult for existing dial gauges to check the depth of the shaft positioning groove, that is, the lower end surface of the shaft positioning groove and the The distance between the upper end face of the big end of the connecting rod is measured
Generally, the depth of the shaft positioning groove is measured by a three-coordinate detection machine, but the operation is complicated and the detection is time-consuming

Description

technical field [0001] The invention relates to the technical field of detection devices for automobile parts, in particular to a structure of a detection tool for a shaft positioning groove of an automobile connecting rod. Background technique [0002] An automobile connecting rod, comprising a large connecting rod end and a small connecting rod end. A shaft positioning groove is arranged on the inner side of the shaft hole of the large connecting rod end. It is difficult for existing dial gauges to check the depth of the shaft positioning groove, that is, the lower end surface of the shaft positioning groove and the depth of the shaft positioning groove. The distance from the upper end face of the big end of the connecting rod is measured. Generally, the depth of the shaft positioning groove is measured by a three-coordinate detection machine, but the operation is complicated and the detection is time-consuming. Contents of the invention [0003] In vi...
