[0014] In order to make the objectives, technical solutions, and advantages of the present utility model clearer, the following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] Refer to Figures 1 - 3 A tooling for detecting the strength of automotive EPB planetary gears as shown, including a base plate 1 and a cylinder seat 2. A cushion block 3 is provided on the base plate 1. A first relief groove 301 and a positioning groove 302 are opened in the middle of the cushion block 3. A gear positioning seat 4 is placed in the positioning groove 302. A through hole is opened in the base plate 1 within the first relief groove 301. A motor 5 is fixedly connected to the base plate 1. A hexagonal column 501 is fixedly connected to the rotating shaft of the motor 5. The hexagonal column 501 is located within the through hole. A driving gear 8 is sleeved on the hexagonal column 501. A lifting cylinder 6 is fixedly connected to the cylinder seat 2. A pressure plate 601 is fixedly connected to the piston rod of the lifting cylinder 6. A rotating cylinder 7 is fixedly connected to the lower part of the base plate 1. A limiting plate 701 is fixedly connected to the rotating table of the rotating cylinder 7.

[0016] The first relief groove 301 communicates with the positioning groove 302. The gear positioning seat 4 is an arc-shaped plate, and a tooth groove is opened on the gear positioning seat 4. The tooth groove on the gear positioning seat 4 is used for positioning and placing the gear to be detected.

[0017] The hexagonal column 501 is provided with an alignment hole, and a laser sensor is provided in the through hole on the base plate 1. The laser sensor is aligned with the alignment hole on the hexagonal column 501. The driving gear 8 is provided with a hexagonal groove corresponding to the hexagonal column 501. After the hexagonal column 501 is aligned, it can ensure that the driving gear 8 can be positioned and placed at the correct angle.

[0018] The pressure plate 601 is provided with a second clearance groove and a third clearance groove, and the second clearance groove and the third clearance groove are respectively arranged corresponding to the limit plate 701 and the driving gear 8. When the pressure plate 601 is pressed down, the second clearance groove and the third clearance groove can prevent the pressure plate 601 from interfering with the limit plate 701 and the driving gear 8.

[0019] The working principle of the utility model is: when the utility model is in use, first select the gear positioning seat 4 corresponding to the gear to be detected and place it on the base plate 1 along the positioning groove 302, then the rotating cylinder 7 drives the limit plate 701 to rotate 180°, so that the limit plate 701 limits the gear positioning seat 4, and then select the driving gear 8 corresponding to the gear to be detected and place it on the base plate 1 along the hexagonal column 501, and then place the gear to be detected on the base plate 1 along the gear positioning seat 4. At this time, the gear to be detected is meshed with the driving gear 8, and the lifting cylinder 6 drives the pressure plate 601 to press down on the pad 3 to further limit the driving gear 8 and the gear positioning seat 4. Finally, the motor 5 drives the driving gear 8 to rotate to apply pressure to the gear to be detected for tooth resistance strength detection. After the detection is completed, the lifting cylinder 6 drives the pressure plate 601 to return to its position. If there is no tooth breakage or crack in the gear to be detected, the detection can be qualified.

[0020] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific implementations. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
