Description

A clamping mechanism for sheet metal parts

Technical Field

The utility model relates to the technical field of sheet metal parts, in particular to a clamping mechanism for sheet metal parts.

Background Art

Sheet metal is a thin metal plate with a thickness of less than 6mm. Generally, sheet metal is processed by cold processing technology including laser cutting, metal drawing, etc., and it needs to be clamped and positioned before processing.

For example, a sheet metal positioning and clamping mechanism with patent number CN218016688U includes a workbench, both left and right sides of the workbench are provided with placement grooves, and the top of the workbench is provided with a collection groove. A blanking frame is provided on the top of the collecting trough, and a hydraulic rod is provided on the bottom of the workbench. The placement trough is internally movably hinged with a No. 1 connecting rod, and the bottom of the No. 1 connecting rod is movably hinged with a No. 2 connecting rod. The left and right No. 2 connecting rods are respectively fixedly connected to the telescopic end and the non-telescopic end of the hydraulic rod, and the top of the No. 1 connecting rod is movably hinged with a No. 3 connecting rod. The above document still has shortcomings. When in use, the top of the contact block is moved toward the top of the inner wall of the slot toward one side of the limit plate, so that the bottom of the contact block produces a slight rolling deformation toward the side of the limit plate. The friction force generated thereby drives the workpiece to be stretched toward the outside of the workbench, so that the workpiece is stretched to a horizontal state. In this way, when laser cutting is performed, the flat workpiece can reduce errors and improve the yield rate. However, after the clamping mechanism in the above document positions the sheet metal, the position of the sheet metal is fixed. When the sheet metal needs to be rotated, the sheet metal needs to be repositioned, which is troublesome to operate and inconvenient to rotate the positioned sheet metal.
