Abstract

The invention discloses a service life test device of a ball screw for a parking clamp. The test device comprises a workbench, a high and low temperature box, a vacuum device, a hydraulic device, a torque device and a PLC control system; the high and low temperature box is arranged at one side of the workbench and used to control the test temperature of the ball screw in the test process, a clamp of the ball screw is arranged in the high and low temperature box, and a force measuring device is arranged between two brake discs; the vacuum device simulates the a vacuum environment of the ball screw in the practical work process, and is communicated with a gas port of the clamp; the hydraulic device simulates a hydraulic environment of the ball screw in the practical work process, and is communicated with an oil port of the clamp; the torque device is arranged at the other side of the workbench, and provides a torsional force for the ball screw; and the PLC control system communicates with the high and low temperature box, the force measuring device, the vacuum device and the hydraulic device and is connected with the torque device.

Description

Technical field [0001] The invention relates to the technical field of a ball screw, and in particular to a life test device and a test method of a ball screw for a parking caliper. Background technique [0002] After the production of the ball screw for parking calipers is completed, most of the life test devices need to test the service life of the ball screw, so that the tester can clearly understand the service life of the ball screw. However, in the prior art, the overall structure of the ball screw test device for testing parking calipers is relatively complicated, and the entire detection process is cumbersome, and it is difficult to accurately test the accurate service life of the ball screw for parking calipers. It is difficult for the tester to accurately understand the service life of the ball screw test for the parking caliper, which brings great inconvenience to the tester. [0003] However, in view of the shortcomings of the existing technology, it is necessary for d...
