Torsion spring fixed angle force measuring device

Abstract

The invention discloses a torsion spring fixed angle force measuring device including a fixed part, a rotation part, and a connection part, wherein the fixed part includes a support seat and a fixed plate, the rotation part includes a rotating plate, the rotating plate includes a base arranged at one end for supporting the bottom of a torsion spring and having a center through hole, a relatively arc-shaped slide rod arranged at one side of the base, protruding out of the base, and inserting into an arc-shaped through groove, and an actuating end arranged at the other end of the rotating plate and coaxial with the base, the torsion spring is coaxially arranged between the base and the actuating end, the connection part includes a core shaft which is a rod body having a protruding round table at one end, the core shaft passes through the center step hole of the flat plate of the support seat, so that the core shaft can be sleeved by the torsion spring, and the end part of the core shaft passing end extends into the actuating end of the rotating plate. The force measuring device, by means of the simple and reliable assembling part, can realize the torsional force test and failure measurement of the torsion spring. The structure is simple and the versatility is strong.

Description

technical field [0001] The invention belongs to the field of torsion spring testing, and more specifically relates to a torsion spring fixed-angle force measuring device. Background technique [0002] After the precision torsion spring is manufactured, it is necessary to carry out torque testing and related tests to detect or test the performance of the torsion spring. [0003] For the torsion test of the torsion spring and the comparison test (failure test) of the torsion spring at any set working angle and maintaining a certain period of time, it is generally completed on the torsion spring torque testing machine at present. The existing torsion spring torque testing machine is complex in structure and expensive, and various simple torsion spring torque measuring devices are often manufactured for a specific torsion spring, which has poor versatility and is not suitable for 100% of the batch needs to be tested , It is also impossible to complete the comparative test (fail...
