Screw destructive torque measuring device and measuring method

Abstract

The invention provides a screw destructive torque measuring device and measuring method. The screw destructive torque measuring device includes: a pedestal, two parallel sides of an upper surface of the pedestal being provided with mutually symmetrical clamping grooves; a pedestal sliding block inserted in the pedestal clamping grooves; a rotating mechanism which is mounted on the pedestal and includes a first lead screw, a first lead screw nut, a first gear, a second lead screw, a second lead screw nut, a second gear, a rotary handle and a third gear; and a clamp module is arranged between the pedestal sliding block and the pedestal and includes a first screw clamp and a second screw clamp whose side edges are provided with grooves respectively, and the grooves being matched and jointly forming a cylindrical groove. The device can rapidly and accurately measure a numerical value of destructive torque of a screw, and can perform measurement circularly, thereby saving resources, and greatly satisfying a requirement of an enterprise for rapidly measuring the numerical value of destructive torque.

Description

technical field [0001] The invention relates to a measuring device and a measuring method, in particular to a screw breaking torque measuring device and a measuring method. Background technique [0002] There are few current measuring devices for screw breaking torque on the market, and most of them are measured directly by punching threaded holes, which directly damages the screw itself. Therefore, this method can only measure the screw breaking torque once, resulting in waste of resources and being unable to test another batch. Secondary screws; and the existing screw destroys the torque measuring device, and also has the problem that it cannot be measured quickly. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a screw breaking torque measuring device and measuring method, which saves resources, is easy to operate, and is highly efficient and accurate. [0004] The present invention is achi...
