Problems solved by technology

At present, the main problems of the test benches used by various enterprises are: 1. It is impossible to simulate high and low temperature, sediment spray and ball stud reciprocating rotation and swing simultaneously on one test bench; 2. The ball stud reciprocating rotation and swing mechanism Using stepping motors, variable frequency motors, hydraulic cylinder drives, etc., the control accuracy and precision are poor, and the operating frequency is low; 3. Only one ball stud assembly can be tested for durability; 4. The fixture is complex and different types of balls There are many clamping parts that need to be replaced during the test of the head pin assembly, and the work is cumbersome

Embodiment Construction

[0019] The test bench of the present invention is mainly composed of a bench, a high and low temperature mechanism, a mud water spray mechanism, a ball stud rotation mechanism, a ball stud swing mechanism, and a PLC control system.

[0020] see figure 1 , The bench adopts industrial aluminum profile frame 1, and the mechanism and components of the test bench are all installed and fixed on the bench. For the beauty and dustproof of the test bench, a stainless steel plate 3 is installed on the surface of the test bench.

[0021] see figure 1 , 2 , the high and low temperature mechanism is mainly composed of a high and low temperature box 2, a high and low temperature generating box 6, and an air conditioning channel pipeline 7, and the high and low temperature box 2 and the high and low temperature generating box 6 are all fixed on the stand. According to the temperature signal of the PLC control system, the temperature of the air in the high and low temperature generating bo...

Abstract

The invention relates to a high and low temperature and muddy water spray endurance test bench of ball stud assemblies. The high and low temperature and muddy water spray endurance test bench is particularly suitable for simulating high and low temperature and muddy water spray endurance quality tests of the ball stud assemblies of an automobile under the real vehicle environment. The high and low temperature and muddy water spray endurance test bench mainly comprises a bench frame, a high and low temperature mechanism, a muddy water spray mechanism, a ball stud rotating mechanism, a ball stud swinging mechanism and a programmable logic controller (PLC) controlling system. The high and low temperature and muddy water spray endurance test bench can simulate high and low temperature and muddy water spray under the real vehicle environment in a high and low temperature tank, achieves reciprocating rotation and swing of ball studs accurately and efficiently by means of the driving of an alternating current servo motor, and can perform the endurance tests on three ball stud assemblies simultaneously. In addition, a clamp is simple in design, convenient and fast to replace and capable of being adaptive to the endurance tests of the ball stud assemblies of different models.

Description

technical field [0001] The invention relates to a high and low temperature muddy water spray durability test bench for a ball stud assembly, which is especially suitable for simulating the high and low temperature muddy water spray durability test of an automobile ball stud assembly in a real vehicle environment. Background technique [0002] The ball stud assembly is mainly composed of a ball stud, a non-metal ball bowl, a back cover, a spherical shell, and a dust cover. It is an important part of the steering mechanism, suspension mechanism, and balance mechanism of the car. Its performance directly affects the controllability and accuracy of the steering, as well as the stability of the chassis suspension. It is very important to the safety of the entire car, so it must be Carry out a strict durability test similar to the real vehicle environment and road conditions. The durability test requires simulating the high and low temperature and muddy water spraying in the real...
