Automatic threading screw machine and screw nut locking device

Abstract

The invention relates to the technical field of assembling of screws and nuts, and provides a screw and nut locking device. The device comprises a mounting rack, a nut locking mechanism, a screw screwing mechanism and a lifting mechanism, wherein nut locking mechanism, the screw screwing mechanism and the lifting mechanism are arranged on the mounting rack; the nut locking mechanism is used for positioning the screw and the nut as well as enabling overlapping of the axes of the screw and the nut; the screw screwing mechanism is used for screwing the screw to rotate about an axis of the screw; the lifting mechanism is used for driving the screw screwing mechanism to move up and down relative to the mounting rack and enabling the contact of the screw screwing mechanism and the top end part of the screw while the screw screwing mechanism moves up and down. Compared with the prior art, the device has the advantages that the screw and nut can be automatically fixed to a workpiece, thus that the screw is ignored to screw can be avoided, the problem of non-uniform screwing force can be solved, and as a result, the product quality can be ensured. The invention further provides an automatic screw assembling machine. Compared with the prior art, the machine has the advantages that the workload of workers can be reduced, thus the labor cost can be decreased, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of screw nut assembly, in particular to an automatic screw threading machine and a screw nut locking device. Background technique [0002] Automatic assembly lines in the electronics industry, such as: mobile phones, hard drives, keyboards, electronic toys, computers, DVDs, home appliances, plastics, electrical appliances, communication equipment, electrical appliances, toys, electronic processing, etc., and automatic assembly of auto parts, such as: motors, Motors, parts, etc., all need to use a large number of screw nuts to assemble the parts. [0003] At present, there is no mature screw and nut locking device on the market. In the assembly and production of products, the traditional assembly method is to use manual penetration, the number of screws is large, the manual workload is large, and the phenomenon of screw leakage is prone to occur; in addition , Manually lock the screw nut to the workpiece, th...
