Automatic screw tightening device

Abstract

The invention is suitable for the technical field of automatic mechanical equipment, and provides an automatic screw tightening device. The device comprises a workbench, and a clamping part arranged on the workbench in a sliding manner and used for clamping and fixing a to-be-screwed workpiece. The workbench is fixedly provided with a plurality of screw locking motors, an output shaft of each screw locking motor is fixedly connected with a torsion sleeve used for tightening a screw, and each to-be-tightened screw is placed in the corresponding torsion sleeve and is aligned with the to-be-screwed position of the to-be-screwed workpiece; and the workbench is further provided with a moving part, and the moving part is connected with the clamping part and drives the clamping part to move on the workbench. According to the embodiment of the device, the to-be-screwed workpiece is clamped by the clamping part, the to-be-screwed workpiece is driven to move by the moving part, and the plurality of screw locking motors drive the torsion sleeves to rotate so as to screw the screws on the to-be-screwed workpiece, so that automatic screw tightening is realized, the plurality of screws can be tightened at one time, and the working efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of automatic mechanical equipment, and in particular relates to an automatic screw screwing device. Background technique [0002] At present, in the domestic manufacturing industry, for the combination and fixation of workpieces, it is often necessary to use screws to lock. Screws are tools that use the physical and mathematical principles of the oblique circular rotation and friction of objects to tighten the parts of the device step by step; The process of tightening screws is repetitive and cumbersome. At present, many production lines in China use manual tightening of screws, which not only greatly increases the input of manpower, wastes a lot of labor, but also has low manual work efficiency. Repeated single operations by workers will also lead to high error rates. ; Therefore, an automatic screw screwing device is needed.
