Abstract

The invention provides a spline gear rolling locating tool and belongs to the technical field of machines. The problem that the qualification rate of existing spline gear rolling is low is solved through the spline gear rolling locating tool. The spline gear rolling locating tool comprises a connection rod and a rotation shaft. A cavity is formed in the front end of the connection rod. The rear end of the connection rod is fixedly connected with a workbench. An adjusting disc and a dial disc are fixedly connected to the outer side wall of the front end of the connection rod. The rear end of the rotation shaft is located in the cavity. The rotation shaft is fixed to the connection rod in the axial direction. A locating disc is fixedly connected to the rotation shaft. A spline mandrel is detachably and fixedly connected with the front end of the rotation shaft. The adjusting disc is located between the dial disc and the locating disc. A groove is formed in the side, close to the adjusting disc, of the locating disc. A locating bolt penetrates through the adjusting disc. A steel ball is arranged at the end, close to the locating disc, of the locating bolt which is sleeved with a spring. On end of the spring is abutted against the locating bolt, and the other end of the spring is abutted against the adjusting disc. The steel ball can be embedded in the groove under the elasticity effect of the spring. The spline gear rolling locating tool has the advantage of improving the product percent of pass.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a spline gear rubbing positioning tool. Background technique [0002] The steering system of an automobile includes a steering shaft. The input end of the steering shaft is connected to the steering wheel through the cooperation of external splines and internal splines, and the output end of the steering shaft is also connected to the steering universal joint through the cooperation of external splines and internal splines. To ensure the consistency of the steering wheel during assembly, the phase angle will be increased at the input and output ends of the steering shaft, and it is necessary to ensure the consistency of the phase angle. [0003] The phase angle is usually controlled and manufactured during the production of extruded external splines. However, this manufacturing method will cause deformation of the internal splines and problems that cannot be detected in time when ...
