Screw tightening shaft device capable of rotating and conducting reciprocating linear movement

Abstract

The invention discloses a screw tightening shaft device capable of rotating and conducting reciprocating linear movement and relates to the field of screw assembling tools. The screw tightening shaft device comprises a rotating and reciprocating linear movement mechanism, a screw distance limiting mechanism and a screw capturing mechanism. The rotating and reciprocating linear movement mechanism is installed in a rotating plate, a first oil-free lining and a second oil-free lining. A first compression spring completes automatic returning after a screw tightening shaft moves. The screw distance limiting mechanism is connected with a guiding pipe through a positioning guiding sleeve and descends along with the screw tightening shaft, and when the screw distance limiting mechanisms descends by a fixed distance, the limiting plate prevents the screw distance limiting mechanism from descending continuously, a second compression spring works, and a screwdriver descends continuously and makes contact with a screw. The screw grabbing mechanism is connected with the positioning guiding sleeve through a magnetic ring fixing part, and the screw is grabbed magnetically. The screw tightening shaft device is ingenious and compact in structure, is applied to an assembling line of domestic electric appliances, and is capable of achieving automatic assembling, effectively improving the product assembling quality and production efficiency and lowering the production cost.

Description

technical field [0001] The invention relates to the field of screw assembly tools, in particular to a screw tightening shaft device capable of rotating and reciprocating linear movement. Background technique [0002] In the flat-panel TV assembly production line, in the screw assembly of the backlight panel and the rear cover, due to the large number of assemblies and the large distribution of equipment positions, in the existing screw assembly process, manual hand-held air batch processing is usually used to complete the process. To ensure the rhythm and balance of the production line, more operators need to be invested to complete the work of the same process. Due to the influence of the production environment, working hours and operator emotions, it is easy to cause missing and wrong installation of screws, which affects the quality of the product. Assembly quality. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies i...
