Automatic locking mechanism and automatic locking filature provided with same

Abstract

The invention discloses an automatic locking mechanism and an automatic locking filature provided with the same. The automatic locking mechanism mainly comprises an installation bottom plate, a first bearing installation plate, a second bearing installation plate, a push assembly, a compression assembly, a precession assembly and a control component, wherein the first bearing installation plate and the second bearing installation plate are fixedly arranged relative to the installation bottom plate; the push assembly is fixed on the installation bottom plate; the compression assembly is arranged on the first bearing installation plate and the second bearing installation plate; the push assembly is used for driving the compression assembly to move vertically downwards; and the precession assembly comprises a pneumatic screw driver for driving a screw to rotate for locking. In the automatic locking mechanism, the working condition of the pneumatic screw driver is controlled through the control assembly, a synchronous belt wheel and an encoder, so that the controllability of a torque signal of the pneumatic screw driver is realized, and the automatic locking speed is greatly increased.

Description

【Technical field】 [0001] The invention relates to the field of machining screw locking, in particular to an automatic locking mechanism and an automatic locking screw machine using the automatic locking mechanism. 【Background technique】 [0002] At present, in the manufacturing industries such as electronic machinery and toy furniture, screw (screw and stud) assembly operations are widely used. In the past, most of the screw assembly operations were manual operations. They were manually placed in the screw holes, and then locked one by one with a screwdriver. tight, low production efficiency, high labor intensity and other disadvantages, which is not conducive to the expansion of the production scale of enterprises and the improvement of production efficiency. With the development of science and technology and the progress of production technology, more and more automation equipment has been put into production line operations. Automation operations have replaced manual simp...
