Abstract

The invention discloses a load-detachable test system for testing the torsional property of a bolt, which comprises the steps of establishing a test platform and testing the torsional property of thebolt, and is used for conveniently realizing the loosening of a nut by unloading a pre-tightening force.

Description

technical field [0001] The invention relates to the field of bolt torsion and pull tests, more specifically, it relates to a load-removable test system for testing the torsion and pull characteristics of bolts. Background technique [0002] The following background art is provided to help the reader understand the present invention and is not to be admitted as prior art. [0003] As the basic test platform in the fastener testing industry, the bolt torsion tension test platform is used to determine the bolt torque-preload conversion ability and other properties. However, the existing bolt torsion and tension test platform is too complicated, the cost is high, and the test platform is large and not easy to carry. In addition, the measurement conditions cannot be met when measuring the torsion-tension characteristics of some special fasteners. For example, when measuring high-lock nuts, the clamping part of the nut head will automatically break and fall off after the nut is t...
