[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] like Figure 1As shown, an embodiment of this application provides a torque testing mechanism, including a workbench 1. The workbench 1 is provided with a carrier assembly 2 for placing products, a limiting assembly 3 for limiting the carrier assembly 2, and a testing assembly 4 for performing torque testing on the products on the carrier assembly 2. The testing assembly 4 includes a horizontal drive mechanism 41, a base plate 42, a rotary drive mechanism 43, a torque sensor assembly 44, and a clamping plate 45. The horizontal drive mechanism 41 is mounted on the workbench 1, and the drive end of the horizontal drive mechanism 41 is connected to the base plate 42. The base plate 42 and the workbench 1 are slidably engaged by a sliding assembly 46. The rotary drive mechanism 43 is mounted on the base plate 42, and the drive end of the rotary drive mechanism 43 is connected to one end of the torque sensor assembly 44. The other end of the torque sensor 44 is connected to the clamping plate 45 by a fixing frame 47. The clamping plate 45 has contact plates 48 at both diagonal ends. The top of the fixing frame 47 is symmetrically provided with two photoelectric sensors 49 for detecting the contact plates 48.

[0019] Specifically, after the assembly mechanism assembles the traction pin onto the product, the carrier assembly 2 moves the assembled product to the testing station. The limiting assembly 3 limits the carrier assembly 2 to prevent it from flipping up and down under force. The horizontal drive mechanism 41 drives the base plate 42 to move the rotary drive mechanism 43, torque sensor assembly 44, and clamping plate 45 toward the product on the carrier assembly 2, so that the clamping plate 45 is clamped on the upper and lower ends of the product assembly part. The rotary drive mechanism 43 drives the torque sensor assembly 44 to rotate the clamping plate 45 90 degrees. The clamping plate 45 drives the product assembly part to rotate 90 degrees. The contact plate 48 on the clamping plate 45 contacts the photoelectric sensor 49, and the photoelectric sensor 49 sends a signal. The torque sensor assembly 44 detects the torque of the product. The rotary drive mechanism 43 continues to drive the clamping plate 45 and the product to rotate. When the rotation reaches 90 degrees, the contact plate 48 contacts the photoelectric sensor 49, and the photoelectric sensor 49 sends a signal. The torque sensor assembly 44 detects the torque of the current product. By performing these tests sequentially, four torque tests can be performed for each rotation of the product. The rotation of the product assembly section drives the traction pin to rotate, thereby detecting the torque between the traction pin and the assembly and mounting sections.

[0020] In the above structure, by setting two contact plates 48 on the clamping plate 45 and cooperating with two photoelectric sensors 49 on the fixing frame 47, the torque sensor assembly 44 performs torque detection four times for each rotation of the product, thereby improving detection efficiency and accuracy. Furthermore, by setting the carrier assembly 2, the limiting assembly 3, and the testing assembly 4 to cooperate with each other, torque testing of the product is achieved, further improving testing efficiency and accuracy.

[0021] like Figure 2As shown, in one embodiment, the torque sensor assembly 44 of the torque testing mechanism includes a support base 441, a torque sensor 442, a first coupling 443, and a second coupling 444. The torque sensor 442 is mounted on the support base 441. One end of the torque sensor 442 is connected to the first coupling 443, which is connected to the rotary drive mechanism 43. The other end of the torque sensor 442 is connected to the second coupling 444. The second coupling 444 passes through a fixing frame 47 and is connected to a clamping plate 45. The second coupling 444 and the fixing frame 47 are rotatably connected via bearings. The rotary drive mechanism 43 drives the first coupling 443 to rotate, which in turn drives the torque sensor 442 to rotate. The torque sensor 442 then drives the second coupling 444 to rotate, which in turn drives the clamping plate 45 to rotate. The clamping plate 45 then drives the assembly part of the product to rotate, which in turn drives the traction pin to rotate. The torque sensor 442 tests the torque between the traction pin and the assembly part and mounting part. This arrangement facilitates torque testing of the product and improves testing efficiency.

[0022] like Figure 2 As shown, in one embodiment, the clamping plate 45 of the torque testing mechanism includes a mounting plate 451 and four grippers 452. The four grippers 452 are symmetrically mounted on the mounting plate 451, with two grippers 452 located at the top of the product and the other two grippers 452 located at the bottom of the product. A horizontal drive mechanism 41 drives a base plate 42 to move the clamping plate 45 toward the product, such that two grippers 452 of the clamping plate 45 are located at the top of the product and the other two grippers 452 are located at the bottom of the product. When a rotary drive mechanism 43 drives the four grippers 452 to rotate, the four grippers 452 cause the product to rotate. This arrangement facilitates the clamping plate 45 to rotate the product, thereby enabling torque testing.

[0023] like Figure 1 As shown, in one embodiment, the carrier assembly 2 of the torque testing mechanism includes a base 21 and a carrier platform 22. The carrier platform 22 is mounted on the base 21, and a positioning pin 23 for positioning the product is provided on the carrier platform 22. The product is placed on the carrier platform 22, and the positioning pin 23 extends into the product mounting part to fix the product mounting part, thereby fixing the product. This arrangement facilitates product fixation.

[0024] like Figure 1 and Figure 2As shown, in one embodiment, the limiting component 3 of the torque testing mechanism includes a limiting seat 32, a limiting block 33, and two L-shaped limiting plates 31. The limiting block 33 is mounted on the limiting seat 32, and the limiting seat 32 and the limiting block 33 are used to limit one end of the carrier assembly 2. The two L-shaped limiting plates 31 are respectively located at the two sides of the carrier assembly 2. One end of the L-shaped limiting plate 31 is mounted on the workbench 1, and the other end of the L-shaped limiting plate 31 contacts the top of the carrier assembly 2. When the carrier assembly 2 moves to the testing station, the limiting seat 32 and the limiting block 33 limit one end of the base 21 of the carrier assembly 2, and the two L-shaped limiting plates 31 limit the top of the base 21 of the carrier assembly 2. This setting can effectively prevent the carrier assembly 2 from moving or flipping when the clamping plate 45 drives the assembly part of the product to rotate, ensuring stability during testing.

[0025] like Figure 1 As shown, in one embodiment, the horizontal drive mechanism 41 of the torque testing mechanism is a cylinder, and the rotary drive mechanism 43 is a motor. The cylinder facilitates the horizontal movement of the base plate 42, which in turn drives the motor, torque sensor assembly 44, and clamping plate 45, improving movement efficiency. The motor facilitates the rotation of the torque sensor assembly 44 and clamping plate 45, improving torque testing efficiency.

[0026] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
