[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching, compounding, bending, riveting, splicing, and forming. In some current mechanical equipment, such as the rear body of a tunneling machine, sheet metal frames are often used as the support structure of the tunneling machine to improve the support and protection of the body. The frame is made of sheet metal, and then the mechanical equipment is fixed and supported by fasteners, thus forming a relatively complete mechanical equipment.

[0003] In terms of installation structure, existing sheet metal frames mostly adopt the bolt-on fastening installation method. Although the connection is stable, it is necessary to rely on the hole alignment for positioning when docking. Due to the lack of docking guide structure, the hole positioning operation is very inconvenient during installation. In addition, due to the lack of calibration limit, the docking of each component requires manual assistance for stabilization, which is very inconvenient to use. Therefore, a sheet metal frame that is easy to disassemble and assemble is proposed. Utility Model Content
