Description

Technical Field

[0001] This utility model relates to the field of sheet metal parts technology, and in particular to a sheet metal parts assembly and positioning device. Background Technology

[0002] Sheet metal parts are components made by processing metal sheets through stamping, shearing, bending, welding, and forming cold working processes. They are characterized by light weight, high strength, controllable precision, and moderate cost. They are widely used in automobile manufacturing, machinery and equipment, electronics, aerospace, and architectural decoration. Common forms include shells, brackets, boxes, and connectors. They can serve as structural supports to bear loads and as aesthetic components to provide protection and aesthetics. They are an indispensable type of basic component in modern industrial production.

[0003] Sheet metal assembly and positioning devices are tooling equipment specifically designed to achieve precise alignment of sheet metal parts during assembly. Through the coordinated action of core components such as positioning pins, positioning blocks, clamping mechanisms, and reference tables, multiple sheet metal parts are quickly positioned, securely clamped, and their posture calibrated according to preset dimensional parameters and assembly accuracy requirements. It is an important process equipment for improving sheet metal assembly efficiency, ensuring product consistency, and structural strength. In use, for sheet metal parts with curved surfaces, angles, and complex hollow structures, traditional rigid positioning devices are difficult to achieve full fit and positioning, easily resulting in local gaps or uneven force, leading to shape deviations after assembly. In existing technologies, positioning devices with modular designs can quickly combine and replace positioning components according to different shapes and structures of sheet metal parts. However, due to the different processed parts, when fixing them, the processed parts may move to unobstructed areas, affecting the efficiency of assembly. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sheet metal assembly and positioning device, which aims to improve the problem in the prior art that, due to the different processed parts, when fixing them, the processed parts may move to unobstructed areas, affecting the efficiency of assembly.
