Screw nut self-locking detection device for recovering screw

Abstract

The invention discloses a lead screw and nut self-locking performance detection device for a recovery lead screw, and belongs to the technical field of mechanical transmission component detection facilities. The device comprises a base, a rotary frame driving mechanism, a rotary frame, a recovery lead screw clamping mechanism, a chuck fixing base lifting driving mechanism, a CCD camera vertical displacement driving mechanism and a CCD camera, wherein a rack is fixed to the upward side of the left end of the base; the rotary frame driving mechanism is arranged on the rack; the rotary frame is connected with the rotary frame driving mechanism, and an adjusting groove is formed in the right side of the rotary frame; the recovery lead screw clamping mechanism is arranged on the right side of the rotary frame; the chuck fixing base lifting driving mechanism is arranged on the portion, corresponding to the recovery lead screw clamping mechanism, at a first end I of the rotary frame and is connected with the recovery lead screw clamping mechanism; the CCD camera vertical displacement driving mechanism is arranged on the portion, corresponding to the right side of the rotary frame, at theright end of the base; the CCD camera is arranged on the portion, facing the right side of the rotary frame, on the CCD camera vertical displacement driving mechanism and is connected with an externalcomputer processing system. The detection efficiency is improved, the operation intensity is reduced, the detection device is simple in structure and convenient to manufacture, and the good scientificity is embodied.

Description

technical field [0001] The invention belongs to the technical field of detection facilities for mechanical transmission parts, and in particular relates to a self-locking detection device for lead screw nuts for recovering lead screws. Background technique [0002] The aforementioned lead screw nuts are also called lead screw auxiliary nuts. The aforementioned reclaimed lead screws refer to the lead screws that are unloaded from various types of scrapped electromechanical equipment with lead screw transmission mechanisms to be recycled and reused. When the equipment is scrapped, the integrity rate of the lead screw and / or lead screw nut of the structural system of the transmission mechanism is relatively high. For example, even if the lead screw has deflection defects, it can be applied to the rotation according to the degree of deflection. There is a significant difference in precision between mechanical and electrical equipment; for example, when the screw nut still has go...

Problems solved by technology

This detection method has the following shortcomings: First, because the self-locking performance of the screw nut depends entirely on the subjective judgment of the operator, it lacks scientificity, because the judgment results vary from person to person, especially, even if the same It is also very likely that people will make different judgments or even make opposite judgments on the self-locking performance of the lead screw nut of the same recovered lead screw at different times and / or different places; second, the test efficiency is low and the work intensity of the tester is high
