Abstract

The invention relates to a torsion tester for a cable branch box. The torsion tester comprises a base, a main body frame, crossbeams, sliding blocks, pulleys, heavy loads, steel cables and jacks, wherein a fixture used for fixing a tested specimen is mounted on the base, the main body frame is mounted above the base, and the crossbeams are levelly and laterally mounted on both the front side and the back side of the corresponding main body frame above the base; the crossbeams adopt a longitudinal regulating structure which can guide upward to downward, both the middle parts of the both ends of the both sides of the crossbeams are connected with a longitudinal thread screw rod which is mounted at the upper part of the main body frame to be driven and regulated, and the crossbeams move up to down along guide rails which are arranged in the main body frame; the crossbeams comprise an upper crossbeam and a lower crossbeam, the sliding blocks are horizontally mounted on the both crossbeams in a sliding manner respectively, and a graduated scale used for measuring is made on each sliding block. All the crossbeams and the pulleys disclosed by the invention adopt adjustable design, the decomposition of force is avoided, the application of the force is more accurate, the error range is within 0.5%, and data of casing deflection can be accurately measured through moving the scales.

Description

technical field [0001] The invention belongs to the detection field of cable distribution boxes, and relates to an electromechanical product for detecting the torsion resistance state of a housing, in particular to a cable distribution box torsion testing machine and a testing method thereof. Background technique [0002] At present, the existing shell torsion resistance test equipment and test methods are relatively primitive, consisting of simple columns, pulleys, heavy loads, etc. During the test, place the shell sample in an area where it can be fixed, and apply force to the shell from two directions through weights, steel cables, pulleys, heavy loads, etc. However, this method is not very applicable, and the test process is time-consuming and laborious. It cannot guarantee the safety of the test personnel and the accuracy of the test. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide ...
