A car-type servo electric cylinder rolling guide rail front and rear fence test bench

Abstract

The invention relates to a test bench for front and rear guardrails of a car-type servo electric cylinder rolling guide rail, which meets the requirements for testing the front and rear guardrails of a car. There are two reaction force clamp base plate assemblies at the front of the test bench, which can slide on the rolling guide rails on the front foundation beam to adjust the proper position and move back and forth through the movable clamp assembly to control the front and rear guardrails of the test piece. Fix it, and then use the electric cylinder rolling slide rail plate assembly to exert force on the guardrail of the test piece to carry out the test process, so as to simulate the real collision to ensure the correctness and authenticity of the test results, and to improve the performance of the guardrail. Good promotion effect; the bottom of the test bench is equipped with universal wheels to facilitate the movement and carrying of the test bench; the present invention uses a servo electric cylinder to control the electric cylinder rolling slide rail plate assembly to carry out the test on the guardrail of the test piece. Apply force to carry out experiments to realize the advantages of a more environmentally friendly environment, more energy-saving and clean, and can ensure high-precision motion control.

Description

technical field [0001] The invention relates to a test bench for inspecting the front and rear guardrails of a car by using a servo electric cylinder. More specifically, the invention designs a test bench for the front and rear guardrails of a car-type servo electric cylinder rolling guide rail. Background technique [0002] At present, with the increase of car ownership, more and more traffic accidents have occurred, which has become a hot issue that people pay attention to. In addition, some scientific researchers are also paying more and more attention to the passive safety of cars. Therefore, in order to improve the safety of people and cars Safety, the guardrail that is set on the car is just particularly important. [0003] At present, there are few test benches for testing the guardrail, or the force applying device used cannot reach a high level, so the collision process in the real scene cannot be simulated. Other test benches are heavy and cannot be moved, so that...

Problems solved by technology

[0003] At present, there are few test benches for the detection of guardrails, or the force-applying devices used cannot reach a high level, so it is impossible to simulate the collision process in the real scene

Other test benches are heavy and cannot be moved, so that the test of the protective fence can only be carried out on specific occasions, and the transfer of the test bench will be particularly cumbersome and laborious.

[0004] At present, some test benches for testing the front and rear guardrails use hydraulic cylinders or pneumatic cylinders. Oil leakage may occur during the use of hydraulic cylinders, resulting in environmental problems; in addition, the use of pneumatic cylinders Noise issues may arise during the
