Description

Bar laser cutting device based on linear guide processing Technical Field The invention relates to the technical field of metal cutting, in particular to a bar laser cutting device based on linear guide rail processing. Background With the rapid development of the fields of mechanical manufacture, automobile industry, aerospace and the like, the processing precision and the production efficiency of hollow bar materials (such as seamless steel pipes, hollow alloy bars and the like) are increasingly required. The laser cutting technology has become the main technical means of hollow bar cutting processing by virtue of the advantages of high cutting precision, small heat affected zone, high cutting speed and the like, and the corresponding bar laser cutting device based on the linear guide rail is also widely applied. In the laser cutting process of the hollow bar, high-temperature slag generated by cutting is easily attached to the inner wall or penetrates through the inner wall to cause damage due to the hollow structural characteristic of the hollow bar, and the processing quality and the subsequent service performance of a workpiece are seriously affected. In order to solve the problem, a mode of inserting a slag removing rod inside a hollow bar is commonly adopted in the prior art, slag is physically blocked by the slag removing rod, and slag is blown away from a notch area by matching with auxiliary gas, so that the inner wall protection and slag removing effect are realized. At present, a bar laser cutting device based on a linear guide rail generally comprises a linear guide rail, a pushing mechanism, a fixed clamp, a laser cutting head, a slag removing rod assembly and the like, and the work flow of the bar laser cutting device is that the fixed clamp clamps and positions a hollow bar, the slag removing rod is inserted into the hollow bar and kept relatively stable, the laser cutting head moves along the linear guide rail or the hollow bar moves along the guide rail to finish cutting, and after single-section cutting is finished, the pushing mechanism drives the hollow bar to feed along the linear guide rail to perform next-section cutting. However, when the existing bar laser cutting device based on linear guide rail processing is used for cutting a hollow bar in cooperation with a slag removal rod, the following key technical defects exist: Because the deslagging rod is required to be always positioned in the hollow bar to play roles in deslagging and protection, when one section of cutting is finished and the next section of feeding pushing is performed, in order to avoid static friction between the fixing clamp and the hollow bar from obstructing pushing action, the fixing clamp is required to loosen clamping of the hollow bar. The hollow bar stock has a certain length, and after the fixing clamp is loosened, the feeding end of the hollow bar stock is extremely easy to sag under the action of self gravity, so that the parallelism deviation between the axis of the hollow bar stock and the linear guide rail is increased, and the hollow bar stock and a slag removing rod or other parts of equipment can be possibly caused to collide and interfere. Disclosure of Invention In view of the problem that sagging easily occurs due to lack of support during feeding of hollow bar stock in the prior art, the bar stock laser cutting device based on linear guide rail processing is provided. The application provides a bar laser cutting device based on linear guide rail processing, which aims to still provide support for hollow bars during feeding of the hollow bars. The technical scheme includes that the bar laser cutting device based on linear guide rail processing is used for processing hollow bars and comprises a base, a transmission device arranged at the top of the base, three moving tables, a clamping assembly arranged in the moving tables, a deslagging assembly arranged in the rightmost clamping assembly, a clamping assembly specifically comprising a ring barrel arranged at the inner side of the moving tables, four sliding grooves formed on the inner ring side of the ring barrel and distributed in an annular array, an outer ring groove formed on the outer ring side of the ring barrel, a clamping block arranged in the sliding groove, a sliding hole formed between the sliding groove and the outer ring groove, a push-pull rod arranged at one end of the clamping block close to the outer ring groove, a rotating ring arranged in the outer ring groove, a state slide rail formed at one side of the rotating ring close to the push-pull rod and a state slide rod arranged at the outer side of the push-pull rod; The clamping blocks extend out of the sliding grooves, the push-pull rods penetrate through the sliding holes to enter the outer ring grooves, the state sliding rods slide in the state sliding ways, the state sliding ways located in the middle moving table are divided into two groups, the state sliding ways locat
