A testing system for the angle and torsion of a torsion spring

Abstract

The invention discloses a torsion spring angle and torque testing system, which comprises a torsion spring fixing plate (4), a torsion spring pressing plate (7), a mandrel (1), a torsion spring bush (3) and a torsion tester, wherein both the torsion spring fixing plate (4) and the torsion spring pressing plate (7) are provided with through holes; the mandrel (1) passes through the through holes; the mandrel (1) is connected with the torsion tester; one end of the mandrel (1) is provided with a dial scale (6); the other end of the mandrel (1) is provided with a rotating shaft (10); the rotatingshaft (10) is provided with a dialing rod (8); the dialing rod (8) is contacted with the bottom part of the torsion spring pressing plate (7); and one sides, close to the dial scale (6), of the torsion spring fixing plate (4) and the torsion spring pressing plate (7) are provided with sharp corners. According to the torsion spring angle and torque testing system disclosed in the invention, through effects of the torsion spring pressing plate and the torsion spring fixing plate, the angle and the torque of the torsion spring can be measured at the same time, and the state of the torsion springcan be stored.

Description

technical field [0001] The invention belongs to the technical field of torsion spring parameter testing, and more specifically relates to a testing system for the angle and torsion of a torsion spring Background technique [0002] Torsion springs (torsion springs) are coil springs. The ends of a torsion spring are secured to other components, and as the other components rotate about the center of the spring, the spring pulls them back to their original position, creating a torque or rotational force. Torsion springs can store and release angular energy or statically fix a device by rotating a moment arm about the central axis of the spring body. These springs are usually close-fitting, however, the coils are spaced to reduce friction, and the ends of the springs can be wound into hooks or straight torsion arms. [0003] The torsion spring uses the elasticity and structural characteristics of the material to produce deformation during work, and converts mechanical work or k...

Problems solved by technology

[0004] However, it is difficult to fix the torsion spring on the torsion testing machine, and the rotation angle of the torsion spring cannot be measured. It is necessary to design a device that can detect the angle and torsion force at the same time, and the tooling is required to press the torsion spring according to the actual installation state for a long time. Stored in a normal temperature environment, there is currently no related torsion spring measurement device
