Precision laser cutting processing equipment is used for cutting and blanking in the sheet metal processing industry. In recent years, due to its fast cutting speed and high production efficiency, the cutting quality is good, the cutting seam is narrow, and there is no tool wear. Whether it is a simple part or a complex part, it can be cut with a laser to achieve precision rapid prototyping, which is widely used in sheet metal processing. At present, the common laser cutting machine needs to be leveled by a leveling machine, the plate is cut into small pieces of steel plates, and then manually transported to the working platform of the laser cutting machine for positioning and cutting, and then manually unload the cut workpieces, stack them neatly, clean up the waste materials, and repeat the feeding process. In addition, the laser cutting machine must stop cutting during the loading and unloading process, which greatly limits the production efficiency of the laser cutting machine and the advantage of fast laser cutting speed. At the same time, loading and unloading requires at least two people to work at the same time.

The purpose of the utility model is to provide a precision laser cutting processing equipment on the basis of the existing technology. The feeder set in the precision laser cutting processing equipment can realize high-precision positioning through the plate limit, and can also automatically correct the deviation during the feeding process, so as to realize the automatic feeding of the plate; the cleaning cutting area and the rotating worktable are set to make the plate clear and cut under the precise positioning of the cleaning cutting area, then it is transported to the rotating worktable to complete the workpiece cutting; the precision laser cutting process of automatic loading and unloading is realized, and the production efficiency is improved. The technical scheme provided by the utility model is: a precision laser cutting processing device, which has a main bed and the following working units set from back to front, namely a feeder, a material cleaning cutting area and a turntable, the material cleaning cutting area and the turntable are fixed on the main bed together, and the feeder is fixed on the ground; the main bed body of the precision laser cutting processing equipment is also provided with a precision laser cutting processing head assembly, installed above the clear cutting area and the rotating table; the precision laser cutting processing equipment feeder is equipped with a feed bed and a feed roller, the feed roller is set at the rear end of the feed bed; the loading roller is equipped with a loading roller bracket,4-9 loading roller shafts and loading roller tubes corresponding to the number of roller shafts; The feed roller bracket of precision laser cutting processing equipment is erected in an arc between the bed of the feeder and the ground, and the upper end of the feed roller bracket is fixed on the feeder and the lower end is fixed on the ground. The loading roller shaft is evenly arranged on the loading roller bracket, and each roller tube body passes through the loading roller shaft; The feeding machine body of precision laser cutting and processing equipment is provided with a feeding table, the front and rear ends of the feeding table are respectively provided with front stops and rear stops, and the lower part of the feeding table is respectively provided with a feeding servo motor and a feeding ball screw. The feeding ball screw of precision laser cutting and processing equipment is longitudinally set, the front and rear ends of the feeding ball screw are respectively connected with the feeding bed, and the feeding servo motor is arranged on the feeding machine body and connected with the feeding ball screw. The rear gear and the front gear of the precision laser cutting equipment are both located on the feeding table, and the rear gear and the front gear are longitudinally symmetrically arranged. There are 1-2 pairs of rear gear and front gear; The front stopper is matched with the front stopper track and the front stopper ball screw on the feeding table, the rear stop cooperates with the rear stop track and the rear stop ball screw on the feed table. The front rail and the rear rail of the precision laser cutting equipment are arranged horizontally, and the left and right ends of the front rail and the rear rail are respectively connected with the feeding bed. The front gear ball screw of the precision laser cutting equipment passes through the front gear and is installed on the front gear track. Each pair of front gear pairs is centrally installed on the corresponding front gear track. The rear gear ball screw passes through the rear gear and is installed on the rear gear rail, each pair of rear gear pairs is centrally mounted on the corresponding rear gear rail.

In the precision laser cutting processing equipment of the utility model, since the front and rear mesh cutting stops are arranged in the mesh cutting area, the plate entering the worktable body can be restricted by accurately positioning and feeding the feeder to a certain position, thereby meeting the position requirements during plate cutting. In specific implementation, the mesh cutting servo motor drives the front mesh cutting ball screw and the rear mesh cutting ball screw, make each pair of front and rear mesh cutting stops move symmetrically left and right respectively, and the width between each pair of front and rear mesh cutting stops is automatically controlled and adjusted by the system. The precise positioning of the plate reduces the deviation between the actual position of the plate and the theoretical correct position, thus ensuring the cutting accuracy of the net material cutting and solving the defect that the ordinary precision laser cutting machine cannot cut the net material. Moreover, when the flat plate moves to the rotary table after cutting, the plate entering the cutting area of the net material is still positioned accurately and is not easy to deflect. So as to realize accurate cutting, reduce the scrap rate of workpieces and improve production efficiency.
