[0002] Planetary gears are one of the main components of automobile differentials. The back of planetary gears is a spherical surface. The manufacturing quality of the spherical surface directly affects the rotation quality of the planetary gear after installation, and ultimately affects the overall performance of the automobile differential. In order to ensure the quality of the spherical surface of the planetary gear, the planetary gear needs to undergo strict spherical surface runout measurement after forging.

Four second support plates 607 are arranged on the connecting plate 602, an L-shaped connecting plate 605 is slidably arranged on the second support plate 607, the third connecting plate 604 is hinged to the L-shaped connecting plate 605, and a limiting arc plate 606 is arranged on the top of the L-shaped connecting plate 605; specifically, when measuring the spherical surface of the planetary gear, the center of the planetary gear can be limited by the provided limiting member 6, so when the spherical measuring instrument 3 is used to measure the spherical surface of the planetary gear, the spherical measuring instrument 3 can be aligned with the center of the planetary gear, so there is no need to spend time adjusting the position of the spherical measuring instrument 3 during measurement, thereby speeding up the measurement efficiency, and it can be more convenient to limit it, avoiding its movement during measurement and affecting the accuracy of its measurement.

[0024] like Figure 3 As shown, the measuring frame 2 is provided with a driving component 4 for driving the spherical measuring instrument 3 to move, and the driving component 4 includes a slide rail 401 arranged at the bottom end of the measuring frame 2, and a first motor 402 is arranged on one side of the slide rail 401. A screw rod 403 is connected to the main shaft end of the first motor 402, and a slider 404 is threadedly connected to the screw rod 403. A first electric telescopic rod 405 is arranged at the bottom end of the slider 404, and the spherical measuring instrument 3 is connected to the telescopic end of the first electric telescopic rod 405; specifically, the operation of the first motor 402 can drive the screw rod 403 to rotate, and the rotation of the screw rod 403 can drive the slider 404 to slide on the surface of the slide rail 401, thereby driving the spherical measuring instrument 3 to move, and the measuring pointer of the spherical measuring instrument 3 can be retracted when in use, so that the spherical surface of the planetary gear can be measured. The spherical measuring instrument 3 set is a prior art, so its principle, structure and model are not described in detail here.

[0025] like Figure 3As shown, a support cover 502 is provided at the bottom end of the first support plate 504, a plurality of balls 503 are evenly provided at the bottom of the support cover 502, and the first motor 402 is arranged inside the support cover 502; specifically, the first motor 402 can drive the support cover 502 to rotate when working, and the support cover 502 can support the first support plate 504, so that the first support plate 504 can remain stable during rotation, thereby ensuring the accuracy of the spherical measurement of the planetary gear.

[0028] like Figure 2 As shown, the second electric telescopic rod 601 is located at the center of the four limiting arc plates 606; specifically, when clamping and limiting the planetary gear, the planetary gear is firstly sleeved on the outside of the limiting arc plate 606, and then the second electric telescopic rod 601 is extended to push the first connecting plate 602 to rise, so that the L-shaped connecting plate 605 can slide on the surface of the second support plate 607, so that the limiting arc plates 606 are away from each other, thereby being able to play a role in center limiting the planetary gear.

[0029] In summary: when measuring the spherical surface of a planetary gear, the planetary gear can first be center-limited by the limiting member 6 that is set. Therefore, when the spherical measuring instrument 3 is used to measure the spherical surface of the planetary gear, the spherical measuring instrument 3 can be aligned with the center of the planetary gear. Therefore, there is no need to spend time adjusting the position of the spherical measuring instrument 3 during measurement, thereby speeding up the measurement efficiency and making it more convenient to limit it, thereby preventing it from moving during measurement and affecting the accuracy of the measurement.
