[0002] A universal joint, namely a universal joint, is a mechanical part that realizes power transmission at a variable angle and is used in positions where the direction of the transmission axis needs to be changed. It is the "joint" part of the universal transmission device of an automobile drive system.

[0003] For the traditional assembly of a universal joint, manual positioning of the hole positions is required. During this process, it is possible to cause inaccurate positioning and the accuracy requirement cannot be achieved, which affects the product quality. At the same time, manual knocking of the bushing is also required for assembly, wasting a large amount of time and manpower and increasing the workload of workers. Summary of the Invention

[0007] Through the above technical solutions, the internal gear can be driven by the second motor, and the inner disk can be driven to rotate by the gear. The inner disk and the outer disk are misaligned, so that the slider slides to achieve the purpose of clamping. The rotation of the motor can adjust the workpiece at any angle.

[0008] As a further improvement of the above solution, three inner disk chutes are provided, and the three inner disk chutes are symmetrically arranged with the center of the inner disk.

When a workpiece is placed, the second motor drives the inner disc. The inner disc chute slides with a circular slider, and the outer disc chute slides with a square slider. The outer disc does not move, so that the inner disc and the outer disc are misaligned, driving the clamping jaws to move, thereby achieving the purpose of locking the workpiece. After the inner disc locks the workpiece, the motor drives the outer disc to rotate, so that the workpiece can be adjusted at any angle.

[0018] In the present utility model, a support table is pushed out by a hydraulic cylinder. Sliders are fixed to the outer wall of the support table, and chutes are provided inside the machine tool.
