Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts testing equipment, specifically a testing device for testing the torque of ball joint assemblies in suspension products. Background Technology

[0002] In the automotive manufacturing industry, the suspension ball joint assembly is a key component connecting the steering knuckle and steering tie rod. It needs to withstand complex forces from the wheels and transmit them to the vehicle body; therefore, the accuracy and stability of its torque are crucial to the vehicle's handling performance and safety. The performance of the ball joint directly affects the normal operation of the vehicle. Since it needs to transmit force and torque, all connecting parts must be rigidly connected to ensure strength and rigidity requirements. Simultaneously, no slippage, deformation, or damage should occur in any component. The ball joint assembly's sway angle, torque, and pull-out force significantly affect the vertical movement and steering motion of the vehicle's wheels.

[0003] Traditional ball joint assembly torque testing is mostly performed manually. This method relies on the operator's experience and skills and is easily affected by human factors, leading to low accuracy of the test results. Existing torque testing equipment often can only perform single-type torque tests and cannot comprehensively evaluate the overall performance of the ball joint assembly. Due to the limitations of the equipment's functions, frequent fixture changes or equipment adjustments are required when testing different models of ball joint assemblies, resulting in low testing efficiency. Therefore, a testing device that can detect both the runout torque and the rotational torque of the ball joint assembly is designed to meet current needs. Utility Model Content

[0022] like Figure 1-5As shown, this utility model addresses the problem that existing torque testing equipment often only performs single-type torque testing, and due to the limitations of the equipment's functions, frequent fixture changes or equipment adjustments are required, leading to low testing efficiency. The present invention provides the following technical solution: A testing device for detecting the torque of ball joint assemblies in suspension products, comprising a base plate 1, a housing 2 disposed on the upper rear side of the base plate 1, a reference fixing seat 3 disposed on the upper front side of the base plate 1, a sensor base 4 and a sensor cover plate 5 disposed in the groove of the reference fixing seat 3, and a torque distribution point disposed between the sensor base 4 and the sensor cover plate 5. Sensor 6 is directly connected to the chassis 2 via a data cable. The chassis 2 houses a power module, intelligent display controller, push-button switches, temperature control switches, a fan, and other electronic components. It requires an external standard 220V AC power supply. The intelligent display controller displays the torque received by the torque sensor 6, and different torque performances can be detected by adjusting the detection modes in the intelligent display controller. A second rotating shaft 7 is located on the left side of the torque sensor 6, and a third rotating shaft 8 is located on the right side of the torque sensor 6.

The tapered positioning block 9 is used to fix the product 10 to be detected; the first gear 11 is located at the left end of the second rotating shaft 7, and the upper side of the first gear 11 meshes with the second gear 12. The second gear 12 is inserted into the first rotating shaft 13, and the upper side of the first rotating shaft 13 is provided with a circular pneumatic finger 14. The upper part of the circular pneumatic finger 14 is detachably equipped with multiple grippers 15 along the circumferential direction. The space between the multiple grippers 15 is used to clamp the product 10 to be tested. A connecting block 16 is provided on the lower side of the first rotating shaft 13. The connecting block 16 is connected to the reference fixing seat 3. A manual valve 17 is provided on the side of the connecting block 16, which can detect the torque performance of the ball pin assembly. It can specifically detect the yaw torque and rotation torque required for suspension products, ensuring the accuracy of the detection method, ensuring the positioning accuracy and data intuitiveness of the product during the measurement process, and greatly improving the measurement efficiency of the product.

[0023] In this embodiment, as Figure 4-5 As shown, the upper part of both ends of the reference fixing base 3 is provided with a first mounting hole 31, and the left part of the connecting block 16 is provided with a second mounting hole 161, which facilitates processing.

[0024] In this embodiment, as Figure 1As shown, two bearings 19 are provided in both the first mounting hole 31 and the second mounting hole 161. A circular washer 20 is provided between the bearings 19, and a retaining ring 21 is provided on the opposite outer side of the bearings 19. The structure is simple and easy to install.

[0025] In this embodiment, as Figure 1 As shown, both the second rotating shaft 7 and the third rotating shaft 8 are connected to the torque sensor 6 via a coupling 23, ensuring a stable connection.

[0026] In this embodiment, as Figure 1 As shown, a limiting block 18 is provided on one side of the coupling 23. The limiting block 18 is connected to the reference fixing seat 3. The bottom of the limiting block 18 is provided with a waist-shaped groove. The limiting block 18 can move back and forth through the waist-shaped groove. When a torque test is performed, the limiting block 18 on the other side will lock the coupling 23 at the swing force end. When a swing force test is performed, the limiting block 18 on the other side will lock the coupling 23 at the torque end.

[0027] In this embodiment, as Figure 1 As shown, two L-shaped speed control valves 22 are provided on the outer wall of the circular pneumatic finger 14 for convenient detection.

[0028] In this embodiment, as Figure 1 As shown, the upper part of the tapered positioning block 9 is provided with fixing holes 91 of different specifications for installing products of different specifications.

[0029] In this embodiment, as Figure 1 As shown, when using it, plug the power plug of the chassis 2 into a 220V socket, open the air valve connected to the manual valve 17, test the action of the circular pneumatic finger 14, and ensure the clamping of the gripper 15; select the corresponding tapered positioning block 9 according to the ball pin size of the product 10 to be tested, and put the tapered positioning block 9 into the end hole of the third rotating shaft 8; set the detection mode of the intelligent display controller, which can select continuous detection mode and peak detection mode, and can detect the torque performance of the ball pin in various directions.

[0030] At the start of the test, the ball pin of product 10 is placed in the tapered positioning block 9. The operator swings the product up and down until the ball pin moves smoothly. In peak detection mode, the starting torque of the swinging torque can be detected. After the movement is smooth, the working torque of the ball pin can be detected. The ball pin of product 10 is placed in the cylinder gripper 15. The operator moves the lever of the manual valve 17 to clamp product 10. Then, the operator rotates product 10 left and right until the ball pin moves smoothly. In peak detection mode, the starting torque of the rotational torque can be detected. After the movement is smooth, the working torque of the ball pin can be detected. After the test is completed, the gripper 15 of the circular pneumatic finger 14 is released and the product is taken out.

[0031] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0032] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
