Automobile shock absorber performance test bench

Abstract

The technical scheme of the invention includes a bed, a protection and control system, a power and transmission system, an upper transmission and force measuring mechanism, a crank connecting rod andworkpiece clamping adjustment mechanism and a fixture; the protection and control system, the power and transmission system, and the upper transmission and force measuring mechanism are connected to the bed by bolts; the crank connecting rod and workpiece clamping adjustment mechanism is connected to a driving shaft of the power and transmission system through a bearing; and the fixture is connected to the crank connecting rod and workpiece clamping adjustment mechanism through a clamping positioning block. The function is to realize the approximate sinusoidal harmonic motion by using a servomotor to drive a crank connecting rod mechanism; a force measurement sensor and a displacement sensor measure the damping force of a damper and the displacement of a damper piston rod; an industrial personal computer calculates and analyzes the sensor data, and displays the damper performance result. The invention is high in test efficiency, is suitable for online testing of a production line, iscompact in structure, and is stable and durable.

Description

Technical field: [0001] The invention relates to an automobile shock absorber performance test bench, which belongs to the field of automobile manufacturing equipment, and its main function is to test the damping force of the shock absorber and display the test result with a dynamometer diagram. Background technique: [0002] The damping force of the automobile shock absorber is tested during the production process, and defects in the structure and process of the shock absorber are found. It is required that the equipment can compress and restore the shock absorber, and record and judge the compressive force and restoring force. The performance test bench of hydraulic automobile shock absorber adopts hydraulic control, which has high cost, large floor area and difficult maintenance. Most of them can only be used in the laboratory and are not suitable for on-line production. Although the traditional mechanical automobile shock absorber performance test bench has solved some s...
