Description

Technical Field

[0001] The utility model relates to the field of torque detection, in particular to a torque detection mechanism of an end face spline CV joint assembly. Background Art

[0002] After the CV joint assembly is assembled, torque testing is required. The torque testing process is as follows: the retainer, inner ring and steel ball need to be rotated a certain angle along the centerline of the outer ring cavity, and then the retainer, inner ring and steel ball need to be driven to rotate circumferentially inside the outer ring cavity to test the rotational torque and ensure that the rotational torque is within the set range. Ordinary shank spline CV joint assemblies can be fixed circumferentially by the shank spline profiling tooling. The servo rotation mechanism drives the profiling tooling to drive the CV joint assembly to rotate. At the same time, the tooling is used to fix the retainer, inner ring and steel ball to rotate a certain angle, and then the rotational torque is tested. However, because the spline of the end face spline CV joint assembly is on the end face, it is impossible to drive the workpiece to rotate circumferentially by fixing the shank. In order to solve the problem of torque detection of the end face spline CV joint assembly, it is necessary to design a torque detection mechanism for the end face spline CV joint assembly. Utility Model Content

[0003] In view of this, the purpose of the present invention is to propose a torque detection mechanism for an end face spline CV joint assembly to solve the problem that the end face spline CV joint assembly cannot drive the workpiece to rotate circumferentially through a fixed handle because the spline is on the end face.
