Description

Technical Field

[0001] The invention relates to the field of detection devices, and in particular to a ball joint multi-operating condition performance detection device. Background Art

[0002] The ball joint structure generally consists of two main parts: a ball seat and a ball pin. The ball seat has a spherical hole corresponding to the ball pin, and the ball pin is composed of a threaded rod and a ball head. When working, the ball pin can rotate and swing in the hole of the ball seat to achieve control of angles and bends. Ball joint structures are widely used in mechanical equipment, usually as connecting accessories between actuators and adjustment mechanisms, such as vibrators, connectors and joints. In the aviation field, ball joint structures are also used to control aircraft wings and tail fins, as well as to adjust the fuselage connection. In addition, ball joint structures can also be used for the connection and bearing of building structures, such as spherical joint supports of bridges and large buildings.

[0003] The ball joint structure will be subjected to the alternating effects of loads such as tension, pressure, radial force, torsion and deflection during the operation of mechanical equipment, and the reliability requirements are extremely high. Patent CN109115378A discloses a ball joint force test device and a test method thereof. Although a test device is provided, the device is too simple and cannot directly test the ball joint. Other devices are required to complete the test. Patent CN206920058U discloses an automotive ball joint debugging fixture. Although the ball joint can be clamped and fixed, it can only perform simple tests on the ball joint and cannot meet the requirements of multiple performance tests.
