Abstract

The invention discloses a damper indicator diagram test fixture which comprises a sleeve, a fixture seat, a wedge-shaped clamp block and a limiting rod, wherein a cone surface arranged on the inner wall of the sleeve is matched with a cone surface of the wedge-shaped block arranged on the fixture seat. During a using process, the sleeve moves only, claming and loosing of the wedge-shaped clamp block are controlled through changes of the diameter of the inner wall of the sleeve, and rapid clamping and disassembly of a damper are achieved during a test process. The fixture is simple in structure, and convenient to assemble and use. The damper is convenient to clamp and disassemble, work intensity of operators is lightened, and test efficiency is improved.

Description

technical field [0001] The invention relates to a dynamometer test fixture which can quickly clamp and disassemble the shock absorber when performing the dynamometer test of the shock absorber. Background technique [0002] When performing the dynamometer test on the shock absorber, the shock absorber needs to be fixedly clamped on the dynamometer. In the past, when conducting tests, a threaded fixture was used, and then the thread on the piston rod of the shock absorber was fixedly connected to the fixture, and then the fixture was fixed on the dynamometer for testing. The use of this fixture requires the operator to screw the piston rod of the shock absorber into the threaded hole of the fixture. After the test, the piston rod of the shock absorber needs to be unscrewed from the fixture, which not only increases the labor intensity of the operator, but also increases the test efficiency. Low. [0003] Chinese utility model CN201653707 discloses an upper chuck clamping de...
