Self-locking imaging detection device for lead screw nuts for recovering lead screws

Abstract

An imaging test device of self-locking property of screw nuts of recycled screws comprises: a base, wherein a light target is arranged on one side of the base, and the side, facing up, of the right end of the base is provided with a frame; a rotary rack driving mechanism is arranged on the frame; a rotary rack connected with the rotary rack driving mechanism, and the left side of the rotary rack is provided with an adjusting groove along the length of the rotary rack; a recycled screw clamping mechanism arranged on the left of the rotary rack; a chuck fixing seat lifting driving mechanism arranged at the first end of the rotary rack and connected with the recycled screw clamping mechanism; a CCD (charge coupled device) camera vertical movement driving mechanism arranged on the base; a CCDcamera arranged on the side, facing the light target, of the CCD camera vertical movement driving mechanism; a laser head arranged on a laser head holder, wherein the laser head holder is clamped to ascrew nut of a recycled screw during testing, and the recycled screw is clamped to the recycled screw clamping mechanism. Detecting the self-locking property of the screw nut is achieved; the structure is simple; manufacturing and operating are convenient; the imaging test device has good applicability.

Description

technical field [0001] The invention belongs to the technical field of detection facilities for mechanical transmission parts, and in particular relates to a screw nut self-locking imaging detection device for recovering a lead screw. 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 lead screw and / or lead screw nut of the structural system of the transmission mechanism has a high probability of being intact. For example, even if the lead screw has deflection defects, it can still be used in different categories according to the difference in the degree of deflection. The rotation accuracy is significantly different from other electromechanical equipment; for another example, ...

AI Technical Summary

Problems solved by technology

This detection method has the following deficiencies: 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; other Third, when encountering a recovery lead screw with a long length and a large diameter, it is usually difficult to complete manual inspection by one person because it is too bulky.
