Automatic detection device of knurling major diameter of gear shaft

Abstract

The present invention provides an automatic detection device of a knurling major diameter of a gear shaft, belonging to the field of mechanical technologies. The problem is solved that a current automatic detection device of a knurling major diameter of a gear shaft is not high in detection accuracy and not high in detection efficiency. The automatic detection device comprises a pedestal, the pedestal is provided with a mounting base 1, a mounting base 2 and a moving rack arranged between the mounting base 1 and the mounting base 2, the upper side of the moving rack is provided with a V-shapedgroove configured to put a workpiece, the mounting base 1 is provided with a tip 1 and a translation mechanism driving the axial reciprocating motion of the tip 1, the inner side of the mounting base2 is provided with a tip 2 and a rotation mechanism driving rotation of the tip 2, the moving rack is provided with a top pressure mechanism capable of abutting the workpiece against the top pressuremechanism on the V-shaped groove, and the moving rack is provided with a measuring head module which can be abutted against the outer side wall of the knurling major diameter of the workpiece. The automatic detection device of the knurling major diameter of the gear shaft is high in detection precision and high in detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of inspection tools, and relates to a detection device, in particular to an automatic detection device for the knurled large diameter of a gear shaft. Background technique [0002] Steering gear shaft, as an important transmission component in electric steering gear, has high quality and precision requirements. Most of the steering gear shafts in the mainstream steering gear products on the market today have external spline structures. Steering gear shaft manufacturers often Processed using machining methods such as rolled splines or tooth rubbing. The detection method basically relies on the manual use of a digital display outer diameter micrometer to detect the large diameter of the knurling. This detection method has large measurement errors and low detection efficiency. The error reaches the largest when detecting external splines with small modules and multiple teeth.
