Abstract

The invention discloses a spring torsion test clamping fixture, and relates to a spring torsion test clamping fixture, for solving the problems of wear generated due to relative torsion between two shafts of a clamping fixture when a conventional test clamping fixture carries out a test, easily generated errors in a torsion spring test and material waste generated because the torsion test fixture can only carry out testing on a torsion spring with a fixed diameter in the prior art. The spring torsion test clamping fixture comprises a first connecting shaft and a second connecting shaft. The first connecting shaft comprises a first shaft and a first cylinder connecting block, the second connecting shaft comprises a second shaft and a second cylinder connecting block, two first flat handles are processed at one end of the first shaft, a first cylindrical boss is processed at the other end of the first shaft, a first cross-shaped groove is processed at the end surface of the first cylindrical boss, two second flat handles are processed at one end of the second shaft, a second cylindrical boss is processed at the other end of the second shaft, and a second cross-shaped groove is processed at the end surface of the second cylindrical boss. The spring torsion test clamping fixture is applied to a torsion spring test.

Description

technical field [0001] The invention relates to a spring torsion test jig. Background technique [0002] The torsion spring is an elastic workpiece, and the spring test fixture is used to measure the instrument of the torsion spring test, but in the prior art, the test fixture is relatively torsionally worn when the two rotating shafts are tested, and errors are easily generated during the torsion spring test, and The torsion test jig in the prior art can only test a torsion spring with a fixed diameter, which wastes materials. Contents of the invention [0003] The content of the present invention is to solve the problem that the two shafts of the test fixture in the prior art are relatively torsionally worn during the test, and errors are likely to occur when the torsion spring is tested, and the torsion test fixture in the prior art can only be used for one A torsion spring with a fixed diameter is tested, and there is a problem of material waste, so a spring torsion t...
