Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a precision sheet metal connection mechanism. Background Technology

[0002] Sheet metal work involves a comprehensive cold-working process for thin metal sheets (usually less than 6mm), including shearing, punching, cutting, compound cutting, bending, welding, riveting, splicing, and forming. Its most significant characteristic is that the thickness of the same part is consistent. Products manufactured using sheet metal processes are called sheet metal parts.

[0003] A search revealed that patent application No. 218984589U discloses a precision sheet metal connection mechanism, including a worktable. A motor that drives a rotating shaft is bolted to the outside of the worktable. A screw that drives a fixed sleeve A and a fixed sleeve B to move is fixed to one side of the rotating shaft, with fixed sleeve A located to the left of fixed sleeve B. The outside of the screw is threaded to both fixed sleeve A and fixed sleeve B. A connecting frame A that drives a fixed frame A to move is welded to the outside of fixed sleeve A, and a connecting frame B that drives a fixed frame B to move is welded to the outside of fixed sleeve B. This device solves the problems of existing precision sheet metal parts, such as inconvenience in fixing the parts, easy wobbling during movement, and difficulty in splicing, which affects usability.

[0004] The aforementioned application document uses two movable sets of fixed brackets to limit and clamp the sheet metal parts between them, so as to facilitate welding connection at the joint of the sheet metal parts. However, firstly, the operation of setting both sets of fixed brackets to move is cumbersome, resulting in low overall connection efficiency. In addition, the lateral movement clamping is not convenient for clamping sheet-like sheet metal parts, and the adaptability is low.

[0005] Therefore, we propose a precision sheet metal connection mechanism. Utility Model Content
