Abstract

The invention discloses a self-positioning multi-angle loading aging test device for multiple torsion springs, which solves the problem that the existing devices cannot meet the requirements of small batch testing. An eccentric through hole (7) is arranged on the pin shaft head (6), and an eccentric pin insertion hole (19) is arranged at equal intervals on the same circumference on the outer end face of the left bracket baffle (1), and the eccentric pin ( 8) Insert it into the eccentric pin insertion hole after passing through the eccentric through hole, and a compression spring ( 9), the F-shaped shift plate (13) is clamped on the F-shaped shift plate clamping positioning platform (12) through the terminal bayonet on it, and the gap between the F-shaped shift plate and the left bracket baffle (1) A torsion spring is sleeved on the pin shaft bar, and the left end of the torsion spring is plugged in the insertion hole (15) of the left end of the torsion spring, and the right end of the torsion spring is clamped on the F-shaped dial. The efficiency of loading aging test is improved, and the test cost is saved.

Description

technical field [0001] The invention relates to a loading aging test device for torsion springs, in particular to an efficient and simple testing device capable of carrying out loading aging tests on a plurality of torsion springs at the same time. Background technique [0002] The torsion spring is a torsion spring, and its two ends are fixedly connected to other components. When other components rotate around the center of the spring, the torsion spring pre-pulls it back to its initial position to generate torque or rotational force, which can be used to store the release angle. Energy or static fixation of certain devices by rotating the moment arm about the central axis of the spring body. After the torsion spring is manufactured, it needs to be subjected to a loading aging test to test whether its performance meets the requirements. The loading aging test is to place the torsion spring on a special tooling, twist it to a specified angle, test its torque value, and then...
