Punching device based on filming and laser positioning and method thereof

Abstract

The invention relates to a punching device based on filming and laser positioning and a method thereof. The punching device comprises a punching drive device, an upper die plate and a punching head and further comprises a clamping device located below the punching head and supporting blocks. The clamping device comprises symmetrically arranged clamping blocks. The clamping blocks are arranged on a bracket by the aid of a spiral shaft. The outer end of the spiral shaft is connected with a handle. The supporting blocks are provided with punched grooves. A laser head is axially arranged in the punching head by the aid of a set screw. A film is attached to the upper surface of the machined part. Hole circles corresponding to machining holes are precut in the film, and inductive color codes are arranged in the centers of the hole circles. According to the punching device, positioning operation is easy and convenient, positioning is accurate, the laser head is arranged in the punching head and does not occupy indoor space, and therefore the laser head can be prevented from being damaged by external collision; as the supporting blocks are arranged on the lower surface of the machined part, overall deformation of the machined part is prevented; the arranged film protects the upper surface of the machined part, so surface scratching is avoided.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a sheet metal punching machine. Background technique [0002] Existing punching devices or punching machines all include a frame, a bottom mold fixed on the frame, an upper template that moves up and down relative to the frame, and a punch corresponding to the bottom mold is fixed on the upper template. , the upper template is connected with the oil cylinder or cylinder that drives it to move up and down. Driven by the oil cylinder or air cylinder, the upper template drives the punch to move up and down relative to the bottom die, so as to punch out the required holes on the workpiece between the punch and the bottom die. The above-mentioned punching device or punching machine generally adopts a manual operation mode, that is, the plate is adjusted by manually adjusting the clamping device to adjust the processing position. The disadvantages are: the positioning o...
