Technical Field

[0001] The utility model belongs to the technical field of 3D laser cutting, and particularly relates to a positioning tooling for 3D laser cutting. Background Technique

[0002] 3D laser cutting technology is an advanced laser cutting method. It scans the surface of the material with a laser beam of high power density, heats the material to several thousand to tens of thousands of degrees Celsius in an extremely short time, melts or vaporizes the material. Subsequently, high-pressure gas is used to blow the melted or vaporized material away from the slit, thereby achieving the purpose of cutting the material. During the cutting process, in order to ensure the stability of the workpiece, the workpiece will be fixed.

[0003] The Chinese patent discloses a tooling fixture for a 3D laser cutting machine (CN219542069U), which includes a tooling table and a locking mechanism. A plurality of adjusting holes are arrayed on the tooling table, and a supporting mechanism is connected to the adjusting holes by bolts in a threaded manner; the supporting mechanism includes a fixing plate and a supporting block. The fixing plate includes a bottom plate and a connecting plate arranged in an L shape. Threaded holes matching the adjusting holes are opened on the bottom plate, and a through groove is opened on the connecting plate. One end of the supporting block is slidably clamped in the through groove, and the supporting block and the connecting plate are locked by a positioning bolt. The locking mechanism is arranged on the bottom plate and is used to fix the automotive sheet on the supporting block. Most of the current positioning toolings only have the function of positioning. After the workpiece is cut, it is not easy to be taken off the cutting table due to the high temperature, which reduces the cutting efficiency of 3D laser cutting. Therefore, a positioning tooling for 3D laser cutting is provided. Summary of the Utility Model

At this time, the gas in the piston cylinder is blown from the nozzle to the outer surface of the workpiece through the connecting pipe to cool the workpiece. By reducing the temperature of the workpiece itself, the taking efficiency of the workpiece is improved, and thus the working efficiency of the cutting machine is improved.

Then the cutting machine cuts the workpiece. After cutting, the double-threaded rod 42 is reversed. At this time, under the action of the thread, the threaded sleeve 43 drives the positioning column 44 to move in the opposite direction. When the double-threaded rod 42 rotates, it will also drive the transmission gear 45 to rotate. At this time, the moving rack 48 moves on the positioning rod 49, so as to drive the push rod 46 to push the workpiece out of the placing table 3 through the connecting rod 47.

At this time, the gas in the piston cylinder 51 is blown from the spray head 54 to the outer surface of the workpiece through the connecting pipe 53 to cool the workpiece.
