Figures 1-5 This application provides an automotive transmission component testing device 100, which is applied to automotive transmission component testing equipment and is used to simulate and test different states and angles of automotive transmission components.

[0051] Please refer to the attached document. Figures 1-5In this embodiment, the automotive transmission component testing device 100 includes a base 10, a tilting seat 20, a rotating seat 30, and a drive assembly 40. The tilting seat 20 is rotatably connected to the base 10 and tilts in the front-to-back direction.

The drive assembly 40 includes a positioning clamp 41, a mounting base 42, a drive motor 43, and a rotating shaft 44. The positioning clamp 41 is mounted on the rotating seat 30 and supports the automotive transmission component. The mounting base 42 is mounted on the rotating seat 30 and is located on one side of the positioning clamp 41. The rotating shaft 44 is rotatably connected to the rotating seat 30 and is located in the test space of the rotating seat 30. The vehicle transmission components and positioning fixture 41 are both located within the test space. The drive motor 43 is mounted on the mounting base 42 and connected to the rotating shaft 44. The rotating shaft 44 rotates under the drive of the drive motor 43 and is used to connect the vehicle transmission components to drive the rotating end of the vehicle transmission components to rotate, so as to test the vehicle transmission components. This allows the vehicle transmission components to be tested during the flipping and rotating process through the cooperation of the flipping seat 20 and the rotating seat 30. The combination of pitch and rotation simulates different angles of the vehicle transmission components, avoiding the limitation of only being able to flip the vehicle transmission components without being able to rotate them, thus improving the test effect of the vehicle transmission component test device 100 on the vehicle transmission components.

[0052] Please refer to the attached document. Figures 1-5 In this embodiment, the base 10 serves as a support part of the automotive transmission component testing device 100, and the base 10 is used to support the flipping seat 20, the rotating seat 30, and the drive assembly 40.

[0053] The flip seat 20 is disposed inside the base 10. The flip seat 20 is rotatably connected to the base 10 and can be flipped in the front-back direction to facilitate adjustment of the position of the flip seat 20 relative to the base 10.

[0054] The rotating seat 30 is disposed on the upper side of the flip seat 20. The rotating seat 30 is rotatably connected to the flip seat 20 and its position is adjusted as the flip seat 20 flips, so that the rotating seat 30 can flip and rotate relative to the base 10.

[0055] The drive assembly 40 is located on the upper side of the rotating base 30. The drive assembly 40 includes a positioning fixture 41, a mounting base 42, a drive motor 43, and a rotating shaft 44. The positioning fixture 41 is mounted on the rotating base 30 and is used to support the automotive transmission component, ensuring the placement position of the automotive transmission component.

This allows the automotive transmission component to be tested during the flipping and rotating process through the cooperation of the flipping base 20 and the rotating base 30. The combination of pitch and rotation simulates different state angles of the automotive transmission component, improving the testing effect of the automotive transmission component testing device 100 on the automotive transmission component.

[0056] Please refer to the attached document. Figures 1-2 In this embodiment, the base 10 includes multiple connecting pipes 11 connected to each other. The arrangement of multiple connecting pipes 11 increases the strength of the base 10, and the multiple connecting pipes 11 form a central receiving space. The flip seat 20 is located in this central receiving space and is rotatably connected to two opposing connecting pipes 11, allowing the flip seat 20 to fully utilize the receiving space and ensuring the flip space of the flip seat 20. This facilitates the base 10 passing over the flip seat 20 through the receiving space. Optionally, the multiple connecting pipes 11 are fixed to the cement floor with expansion bolts. Vibration damping pads isolate and attenuate the transmission of vibration between the multiple connecting pipes 11 and the cement floor, ensuring the stability of the base 10 relative to the ground.

[0057] Two rotary bearing seats 12 are provided between the flip seat 20 and the two opposite connecting pipes 11. The fixed ends of the two rotary bearing seats 12 are respectively connected to the two opposite connecting pipes 11, and the two ends of the flip seat 20 are respectively connected to the rotating ends of the two rotary bearing seats 12, which ensures the rotation effect of the flip seat 20 relative to the two opposite connecting pipes 11.

[0058] Please refer to the attached document. Figures 1-5In this embodiment, the automotive transmission component testing device 100 further includes a flipping power module 50, which includes a first motor 51, a first gear 52, and a gear ring 53. The first motor 51 is mounted on the base 10 and connected to the first gear 52 to drive the first gear 52 to rotate, thus ensuring the rotation effect of the first gear 52 under the drive of the first motor 51. The gear ring 53 is fixedly connected to the flipping seat 20. The peripheral sidewall of the gear ring 53 is provided with a rack portion 531, which is arranged in an arc shape and meshes with the first gear portion 52 of the first gear 52. The first gear 52 rotates under the power of the first motor 51, driving the gear ring 53 to rotate, so that the flipping seat 20 can be flipped in the front-back direction. This facilitates the flipping effect of the first motor 51 driving the flipping seat 20 to flip through the cooperation of the first gear 52 and the gear ring 53, thereby achieving the flipping effect of the flipping seat 20 relative to the base 10. Optionally, the tilt angle of the flipping seat 20 is -60° to 60°.

[0059] Please refer to the attached document. Figures 1-4 In this embodiment of the application, a first transmission module 54 is provided between the first motor 51 and the first gear 52. One end of the first transmission module 54 is connected to the output end of the first motor 51, and the other end of the first transmission module 54 is connected to the first gear 52, so that the power output by the first motor 51 can be transmitted to the first gear 52 through the first transmission module 54, thus ensuring the rotation effect of the first gear 52.

[0060] Please refer to the attached document. Figures 1-4 In this embodiment, the automotive transmission component testing device 100 further includes a locking member 60, which is connected to the base 10 and disposed on one side of the gear ring 53. The peripheral sidewall of the gear ring 53 is provided with an arc-shaped boss 532. The locking member 60 is provided with a housing 61 and a locking block 62. The locking block 62 is telescopically connected to the housing 61 to facilitate adjustment of the position of the locking block 62 relative to the housing 61. When the locking block 62 is extended, it gradually approaches the arc-shaped boss 532 and can contact the arc-shaped boss 532 to lock the gear ring 53, thereby stopping the rotation of the gear ring 53 and making it easy for the gear ring 53 to be stationary in time.

[0061] Please refer to the attached document. Figures 1-4 In this embodiment, multiple locking members 60 are provided. The multiple locking members 60 are arranged at intervals along the arc direction of the arc-shaped boss 532 and can contact different positions of the arc-shaped boss 532. By arranging multiple locking members 60, the locking strength of the locking members 60 relative to the toothed ring 53 is increased. When one locking member 60 fails, the remaining locking members 60 maintain the locking effect relative to the toothed ring 53, thus avoiding the failure of the locking effect.

[0062] Please refer to the attached document. Figures 1-3In this embodiment, the rotating seat 30 is connected to an internal gear ring 31. The inner wall of the internal gear ring 31 is provided with a third gear portion 311, which is arranged along a circumferential direction. The automotive transmission component testing device 100 also includes a second motor 70, a second transmission module 80, and a second gear 90. One end of the second transmission module 80 is connected to the second motor 70, and the other end is connected to the second gear 90, driving the second gear 90 to rotate. This ensures that the power output by the second motor 70 is transmitted to the second gear 90 via the second transmission module 80, guaranteeing the automated rotation effect of the second gear 90. The second gear 90 is located on the inner wall of the internal gear ring 31, and its second gear portion meshes with the third gear portion 311 of the internal gear ring 31, allowing the second gear 90 to drive the internal gear ring 31 to rotate, thereby achieving the effect of rotating the rotating seat 30 in a horizontal direction. Optionally, the rotation angle of the rotating seat 30 is -45° to 45°.

[0063] Please refer to the attached document. Figures 1-4 In this embodiment, the positioning fixture 41 is provided with a positioning groove 41a, the opening of which extends upward. The inner wall of the positioning groove 41a contacts the outer wall of the vehicle transmission component to achieve positioning of the vehicle transmission component. The vehicle transmission component is subjected to positioning forces from the positioning fixture 41 in multiple directions, ensuring the positional accuracy of the vehicle transmission component relative to the positioning fixture 41 and preventing the vehicle transmission component from easily detaching from the positioning fixture 41. A rotating shaft 44 is disposed on one side of the positioning fixture 41 and faces the positioning groove 41a in a horizontal direction to engage with the vehicle transmission component located in the positioning groove 41a, thereby connecting the rotating shaft 44 to the vehicle transmission component.

[0064] Please refer to the attached document. Figure 1 In this embodiment of the application, the automotive transmission component testing device 100 also includes a cover 91, which is installed on the rotating seat 30 and covers the rotating shaft 44 and the positioning clamp 41, so that the cover 91 can prevent the automotive transmission component from flying out of the external environment during the test, thereby improving the safety of the automotive transmission component testing device 100.

[0065] The automotive transmission component testing device 100 is equipped with an inclination sensor connected to the lower side of the rotating base 30. The inclination sensor enables closed-loop control of the automotive transmission component's attitude to achieve precise attitude angle control, monitor the operating status of the automotive transmission component in real time, and provide real-time feedback data to the test engineer to ensure the safety of the entire test and to observe the status changes of the entire automotive transmission component in real time.
