Description

Technical Field

[0001] The utility model relates to the technical field of limit clamps, in particular to a limit clamp for sheet metal part processing. Background Art

[0002] Sheet metal is a comprehensive cold working process for thin metal. Its remarkable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. For the processing of sheet metal parts, sheet metal part clamps are often needed.

[0003] The existing sheet metal part clamps include limit clamps and positioning clamps. Two limit clamps are used to limit the position of the sheet metal part on the workbench. However, since the limit clamps are in sliding contact with the sheet metal part, if the limit clamps move excessively, it will be difficult to push the sheet metal part due to excessive friction. If the movement is not in place, the stability of the sheet metal part will be poor, seriously affecting the processing quality and speed of the sheet metal part. Therefore, it is necessary to design a limit clamp for sheet metal part processing to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a limit clamp for sheet metal part processing.

Two connecting blocks are arranged on both side walls of the slide rails. A first screw is arranged on the connecting block. A driving mechanism for driving the sliding plate to move is arranged in the slide rails. The driving mechanism includes a first screw rod arranged in the slide rails. One end of the sliding plate is fixedly connected with a positioning block. A plurality of balls are arranged on the side wall of the positioning block. An installation frame is arranged on the side wall of the positioning block. A moving plate is arranged in the installation frame. A stop rod penetrates through the side wall of the moving plate. An adjusting mechanism for adjusting the position of the moving plate is arranged on the installation frame.

[0007] Preferably, the adjusting mechanism includes a second screw rod arranged in the installation frame. One end of the installation frame close to the slide rail penetrates through the side wall of the moving plate.

[0008] Preferably, a positioning bolt is arranged on the upper end of the moving plate. The cross section of the stop rod is L-shaped.
