[0022] The three-station steering ball joint durability test device includes a base 1, a swing plate 4, a push-pull assembly 6, a swing motor 2, a rotating shaft 5 and a drive motor 7 (see the attached manual). Figure 1 and 2 ).

[0023] The base 1 is provided with a swing plate 4 (see the appendix of the manual) through a swing motor 2 and a swing arm 3 arranged symmetrically. Figure 2 When the swing motor 2 is working, it can drive the swing plate 4 to swing back and forth through the swing arm 3.

[0024] The upper end of the swing arm 3 is equipped with an indicator needle 19; the swing motor 2 on one side of the indicator needle 19 is equipped with an angle dial 20 (see the appendix of the manual). Figure 4 During operation, the swing angles of the swing arm 3 and the swing plate 4 can be monitored by the indicator needle 19 and the angle scale 20.

[0025] The swing plate 4 is provided with a plurality of rotating shafts 5 (see the appendix of the specification) at intervals. Figure 3 and 6 A driving motor 7 is fixed to one end of the swing plate 4; an active swing arm 8 is fixed to the lower end of the driving motor 7; a driven swing arm 9 is fixed to the lower end of the rotating shaft 5; the active swing arm 8 and the driven swing arm 9 are connected to the bearing through a transmission connecting rod 10 (see the attached manual). Figure 6 The lengths of the active swing arm 8 and the driven swing arm 9 are the same (see the appendix of the manual). Figure 6 When the driving motor 7 drives the active swing arm 8 to swing back and forth, the driving connecting rod 10 and the driven swing arm 9 can drive each rotating shaft 5 to rotate back and forth (see the attached manual). Figure 3 and 6 ).

[0026] The upper end of the rotating shaft 5 is provided with a semicircular sleeve 11; the upper end of the semicircular sleeve 11 is fixed with a positioning cover 12; the middle of the positioning cover 12 is provided with a positioning hole 13 and a locking nut 14 (see the attached manual Figure 5 During operation, the ball pin of the workpiece (steering ball joint) can be fixed on the positioning cover 12 through the locking nut 14 (see the appendix of the manual). Figure 5 ).

[0027] The base 1 inside the rotating shaft 5 is equipped with a push-pull assembly 6 (see the appendix of the manual). Figure 1 and 2 ).

[0028] The push-pull assembly 6 includes a high-frequency vibration motor 15, a ball connector 16, a push-pull rod 17 and a locking sleeve 18; one end of the high-frequency vibration motor 15 is equipped with the push-pull rod 17 through the ball connector 16; one end of the push-pull rod 17 is threadedly connected to the locking sleeve 18 (see the appendix of the manual). Figure 8 and 9 ).

[0029] The purpose of configuring the push-pull assembly 6 in this manner is to ensure that, during operation, the locking sleeve 18 can smoothly maintain a threaded connection with the connecting rod of the workpiece (steering ball joint) in cooperation with the ball joint 16. This ensures that during operation, the high-frequency vibration motor 15 can drive the connecting rod of the workpiece (steering ball joint) back and forth through the ball joint 16, the push-pull rod 17, and the locking sleeve 18.

[0030] This three-station steering ball joint durability testing device operates by first securing the ball stud of the workpiece (steering ball joint) to be tested to the positioning cap 12 at the upper end of the rotating shaft 5 via the locking nut 14. The connecting rod of the workpiece (steering ball joint) is then connected to the push-pull rod 17 of the push-pull assembly 6 via the locking sleeve 18, completing the installation of the workpiece (steering ball joint).

[0031] After the workpiece (steering ball joint) to be inspected is installed, the high-frequency vibration motor 15 drives the connecting rod of the workpiece (steering ball joint) back and forth through the ball joint connector 16, push-pull rod 17, and locking sleeve 18. Simultaneously, the swing motor 2 drives the swing plate 4 back and forth via the swing arm 3. During this swing, the swing plate 4 drives the ball stud of the workpiece (steering ball joint) relative to the connecting rod via the rotating shaft 5. Furthermore, during this process, as the drive motor 7 drives the active swing arm 8 back and forth, it drives the various rotating shafts 5 to reciprocate via the transmission connecting rod 10 and the driven swing arm 9. This reciprocating rotation of the rotating shaft 5 drives the ball stud of the workpiece (steering ball joint) relative to the workpiece (steering ball joint).

[0032] In this way, the steering ball joint durability test device can drive the ball stud of the workpiece (steering ball joint) relative to the workpiece (steering ball joint) from three directions. In this way, the steering ball joint durability test device can simulate the actual conditions of the workpiece (steering ball joint). After a period of time, the condition of the steering ball joint is checked to complete the durability test. The steering ball joint durability test device can then enter the next working cycle.

[0033] The three-station steering ball joint durability testing device has a compact structure and ingenious design. It can force the workpiece to be subjected to force from three directions, thereby achieving the purpose of simulating the real situation of the steering ball joint. This solves the problem of poor detection effect in existing automobile steering ball joint durability tests and is particularly suitable for the needs of steering ball joint durability testing.
