Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a positioning device for sheet metal processing which can improve accuracy. Background Art

[0002] Sheet metal parts are metal components formed through sheet metal processing and stamping. Materials primarily include steel, stainless steel, and aluminum alloys. Sheet metal processing involves a series of processes, including cutting, blanking, bending, and forming. Regardless of the product being processed, sheet metal requires stamping to create a specific shape and size. Fixing the sheet metal is a necessary step before stamping.

[0003] A positioning device for sheet metal processing disclosed in the Chinese utility model patent application disclosure CN215431811U is a downward pressing and fixing device composed of a screw, a limiting guide plate, a pressure plate, a round rod, a limiting block, and a spring. It only needs to rotate the screw. Since the screw and the pressure plate are rotatably connected, the pressure plate moves downward under the action of the screw, thereby fixing the pressure plate to be cut. When raised, the spring is in a stretched state and always exerts a pulling force on the pressure plate, which offsets the gravity of the pressure plate, so that it is more labor-saving to rotate the screw to lift the pressure plate. However, the overall flexibility of the positioning device for sheet metal processing is low. After the sheet metal is positioned, it is not convenient to adjust the position of the sheet metal according to the actual processing requirements of the sheet metal, thereby affecting the speed and convenience of subsequent sheet metal processing.

[0008] Preferably, one side of the positioning rod is fixedly connected to a movable block, and one side of the movable block is fixedly connected to a pull rope.

[0009] Preferably, one side of the movable block is fixedly connected with a spring, and the movement of the movable block can squeeze the spring on one side. At the same time, due to the reaction force of the squeezed spring, the movable block can be pushed to reset.

[0010] Preferably, an insert block is fixedly connected to the bottom end of the fixing plate, a positioning hole is provided on one side inside the insert block, and a positioning rod is movably connected inside the positioning hole.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This positioning device for sheet metal processing, which can improve precision, has a first servo motor installed inside the base. When the first servo motor is started, it can drive the threaded rod to rotate. At this time, the threaded block on the threaded rod can drive the movable seat and the workbench at the top to move horizontally. At the same time, the second servo motor in the movable seat is started, which can drive the gear to rotate. The gear can push the rack seat at the bottom of the workbench, and the workbench drives the sheet metal part positioned at the top to move longitudinally. The operation is simple and convenient. By quickly adjusting the position of the sheet metal part, the precision of subsequent sheet metal processing is improved.

[0013] 2. This positioning device for sheet metal processing can improve the accuracy. A plug-in block is fixedly connected to the bottom end of the fixed plate. When the plug-in block is inserted into the inside of the workbench, the positioning rod movably connected in the workbench is inserted into the positioning hole on the plug-in block, so that the fixed plate can be installed on the top of the workbench. When the handle on the workbench is turned, the handle drives the winding roller to rotate, so that the winding roller can pull the draw ropes on both sides to reel in. At this time, the draw ropes can be pulled out of the positioning holes on the plug-in block by the movable block, thereby completing the rapid disassembly of the fixed plate. The modular design reduces the overall maintenance cost of the positioning device for sheet metal processing. BRIEF DESCRIPTION OF THE DRAWINGS
