A nut turning screw machine

Abstract

A nut rotating screw machine, comprising a male screw vibration screening plate, a male screw clamping mechanism, a male screw propulsion mechanism, a nut vibration screening plate, a nut tightening mechanism, a product fixing fixture, and a positioning mechanism. The male guide rod is connected with the screw male clamping mechanism, the nut vibrating screening plate is used to arrange the nuts in an orderly manner and transport them to the nut tightening mechanism, and the positioning mechanism puts the screw in the screw male clamping mechanism The screw male, the nut in the nut tightening mechanism, and the product in the product fixing fixture are positioned. After the positioning is completed, the nut tightening mechanism performs tightening work, and at the same time, the screw male propulsion mechanism pushes the screw male to the direction of the nut. Complete the tightening work of a screw male and a nut. The technology of the invention can replace the traditional manual nut tightening work, the production efficiency is high, the stability is good, the production cost is low, and the labor degree of manual operation is reduced at the same time, so that the production process is more reasonable.

Description

technical field [0001] The invention relates to an automatic screw-tightening device, in particular to an automatic screw device in which the male screw cannot be rotated but is rotated by a nut. Background technique [0002] At present, the application of automatic screwing machine technology in the field of electronic technology has been very mature. Various electric and pneumatic components are used to realize the automatic conveying, tightening and testing of screws, and the screw fastening process is simplified through equipment to reduce the number of labor and It is a typical non-standard automation equipment to reduce the adverse factors caused by manual misoperation. Automatic locking screw machines are mainly divided into: hand-held screw locking machines, multi-axis automatic locking screw machines, and coordinate automatic locking screw machines, but these automatic locking screw machines are all automated by rotating the screw; but currently in furniture hangers...

AI Technical Summary

Problems solved by technology

Automatic locking screw machines are mainly divided into: hand-held screw locking machines, multi-axis automatic locking screw machines, and coordinate automatic locking screw machines, but these automatic locking screw machines are all automated by rotating the screw; but currently in furniture hangers In the fixed manufacturing process, there is a process of clamping the chuck on the A-pillar, screwing the screw on the chuck, and fixing it on the A-pillar with nuts to ensure that the chuck is stable and does not fall off; but because the screw is special, the screw is required The male fixation does not rotate, and the nut rotates to lock and fix, so it is currently done manually, which not only reduces production efficiency, but also makes it difficult to guarantee product quality. The assembly efficiency is low and the product quality is unstable, especially in the process of mass assembly, the product quality is not uniform, the on-site screw drop and other problems will greatly affect the production of the product; therefore, it is necessary to develop a screw Automatic screw device that can't rotate and rotates by nut
