[0024] ReferenceFigure 1 and Figure 2 The workpiece clamp 1 comprises a body 11, a sleeve 12, a pull rod 13, a positioning block 14 and a positioning base 15. The pull rod 13 is slidingly connected to the body 11, so that the pull rod 13 can move up and down on the body 11. One end of the body 11 is provided with a tapered portion 111. The sleeve 12 is sleeved on the tapered portion 111. The sleeve 12 has a certain taper. The pull rod 13 is connected with the sleeve 12, so as to control the relative position of the sleeve 12 and the tapered portion 111, and further make the sleeve 12 expand or reset. The outer diameter of the sleeve 12 matches the inner wall of the differential 6. When the sleeve 12 is expanded, the workpiece clamp 1 fixes the position of the differential 6 on the workpiece clamp 1 through the sleeve 12. When the sleeve 12 resets, the workpiece clamp 1 no longer expands and fixes the differential 6, so as to facilitate the replacement of the next differential 6 to be tested. The positioning block 14 is arranged at one end of the body 11 towards the differential 6. The positioning block 14 is used to support and position the differential 6 on the body 11, so that the positioning block 14 can support the end face of the differential 6, and further support the differential 6 on the workpiece clamp 1 in a radial direction. The body 11 is installed on the positioning base 15. The positioning base 15 is rotatably installed on an external support platform through a bearing. When the workpiece clamp 1 expands the differential 6, the standard gear 3 drives the differential 6 to rotate for testing.

The second measuring rod 5 is used to measure the position of the other end of the differential 6, so as to know the position of the differential 6 on the workpiece clamp 1, and further calculate the position compensation amount, so as to control the standard gear 3 to start moving and engage with the gear of the differential 6 through an external control system.
[0027] The operation process is as follows: the manipulator moves the differential 6 to the workpiece clamp 1, and the outer end surface of the differential 6 falls on the positioning block 14, then the tailstock center 2 is moved downward and tightly presses in the radial hole at the other end of the differential 6, when the position sensor is triggered, it indicates that the downward pressing is in place, then the external mechanism pulls the pull rod 13 to move downward and drives the expansion sleeve 12 to move downward, under the action of the taper part 111, the expansion sleeve 12 expands outward and is pressed against the inner wall of the radial hole at one end of the differential 6 to fix the position of the differential 6, then the external mechanism drives the first measuring rod 4 and the second measuring rod 5 to move and contact the two ends of the differential 6 to measure the upper and lower shaft diameters of the differential 6 and calculate the compensation amount, the external mechanism drives the standard gear 3 to move and engage with the gear of the differential 6, and then the set simulation working conditions such as torque, rotating speed, time, acceleration and the like are detected.
