Abstract

The invention discloses a device capable of performing a self-positioning multi-angle loading aging test on multiple torsional springs. The problem that an existing device cannot meet the requirementfor a small batch of testing is solved. Eccentric through holes (7) are formed in a hinge pin head (6), eccentric pin insertion holes (19) are arranged in the same circumference on the end face of theouter side of a left support baffle (1) at equal interval radian, eccentric pins (8) run through the eccentric through holes to be inserted into the eccentric pin insertion holes, a pin shaft rod (5)between the outer side face of a right support baffle (2) and a check ring (10) is sleeved with a compressed spring (9), an F-shaped switching plate (13) is clamped to an F-shaped switching plate clamping positioning table (12) through an end clamping opening in the F-shaped switching plate, a pin shaft rod between the left support baffle (1) and the F-shaped switching plate is sleeved with a torsional spring, the left end of the torsional spring is inserted into a torsional spring left end insertion hole (15), and the right end of the torsional spring is clamped to the F-shaped switching plate. The loading aging testing efficiency 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...
