Embodiment Construction
[0022] The present invention will be further described below according to the accompanying drawings.
[0023] The connection and coordination relationship between the test sample and the assembly bench, pneumatic system and control system of the durability test device for the automobile rotary connector is as follows: figure 1 shown. The test samples include steering gear, steering column, steering wheel and automotive rotary connectors and other steering system installation parts, and are not used in vehicles. The test sample is assembled and adjusted on the assembly bench, and fixed, and the rotary connector is installed in the steering wheel according to the product technical conditions.
[0024] see figure 1 , figure 2 and image 3 , the assembly platform includes a first base 1 and a second base 22 adjacent thereto, and a first steering gear fixing seat 2 and a second steering gear fixing base 3 are arranged on the right part above the first base. The middle pa...

The invention discloses a durability testing device for an automobile rotary connector which is formed by connecting an assembling rack, a pneumatic system and a control system; the assembling rack comprises a first base and a second base; the first base is provided with a first steering gear fixing base, a second steering gear fixing base, a clockwise rotating opening and closing bracket and an anticlockwise rotating opening and closing bracket, a first air cylinder fixing base and a second air cylinder fixing base; an air cylinder is clamped at the upper parts of the first air cylinder fixing base and the second air cylinder fixing base; the right end of the air cylinder is connected with the left end of a connecting screw rod, the right end of the connecting screw rod is connected withthe left end of a steering gear of a testing part; the pneumatic system comprises a pneumatic box, an air pressure adjusting valve, a reversing solenoid valve and a barometer; and the control system comprises a DC power supply and a control box connected with the DC power supply. The device in the invention can reach the reliability of the rotary connector of the actual automobile validation and can ensure the accuracy of the test result; the device is low cost, simple in operation, reliable in running, and suitable for the durability tests of various automobile rotary connectors.
Description
technical field [0001] The invention belongs to a testing device for automobile parts, in particular to an assembly platform of a durability testing device for a rotary connector of an automobile. Background technique [0002] The car rotary connector is usually installed in the space between the steering wheel and the steering column combination switch. When the car is running normally, it rotates synchronously with the steering wheel to maintain a reliable connection between the two relative rotating parts of the steering wheel and the steering column switch. electrical connection. It is an important part of the car, and its durability plays an important role in the reliability of the car system. [0003] Existing suppliers generally only conduct single-body durability tests on automotive rotary connectors, and cannot simulate systematic tests under real vehicle conditions (that is, the state when the steering column, combination switch and steering wheel are connected), ...
