Auxiliary positioning mechanism for precise sheet metal processing

Abstract

The invention discloses an auxiliary positioning mechanism for precise sheet metal processing. The auxiliary positioning mechanism comprises a material table and a workpiece, wherein a trough is formed in the top of the material table; a positioning table is fixedly mounted at the top of the material table; a limiting block is fixedly mounted at the right side of the positioning table; a first rotating cavity is formed in the positioning table; a second rotating cavity is formed in the middle of the first rotating cavity, and the lower end of the inner cavity of the second rotating cavity is movably sleeved with a limiting ring; a conversion column is fixedly sleeved with the limiting ring, and the outer surface of the conversion column is movably sleeved with a first reset spring; and a connecting column is fixedly mounted at the lower end of the conversion column. The pressure applied to a fixing plate by the conversion column is adjusted by controlling the distance, pushed leftwards by the workpiece, between the extrusion column and the positioning plate, so that the positioning function of the workpiece before fixing is completed, and the sequential synchronization function of the height is achieved through of positioning and fixing of the workpiece.

Description

technical field [0001] The invention belongs to the technical field of precision sheet metal processing, in particular to an auxiliary positioning mechanism for precision sheet metal processing. Background technique [0002] Precision sheet metal processing refers to the methods and process parameters including cutting, blanking and bending forming for metal sheets below 6 mm. The processing of metal sheet parts is called sheet metal processing. In the process of precision sheet metal processing A laser cutting machine will be used to laser cut precision sheet metal parts. Therefore, it is necessary to perform auxiliary positioning before fixing the workpiece before processing. [0003] At present, the precision sheet metal will be clamped and fixed above the fabric groove on the machine before processing, and the positioning method is mainly combined with the fixed structure. Therefore, the positioning and fixing are carried out together, which brings a problem. For The po...
