Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting equipment, and in particular to a fiber laser cutting machine. Background Art

[0002] Fiber laser cutting machine is a laser cutting machine that uses fiber laser generator as light source. Fiber laser is a new type of fiber laser developed internationally that outputs high energy density laser beam and focuses it on the surface of the workpiece, so that the area on the workpiece irradiated by the ultra-fine focal spot is instantly melted and vaporized to achieve automatic cutting.

[0003] Existing fiber laser cutting machines generally load one workpiece at a time, such as a pipe to be cut, unload the pipe after cutting, and then load another pipe to be cut, which reduces the cutting efficiency. In addition, the existing loading fixtures are generally horizontally fixed for loading, except for single-piece loading, which is not conducive to oblique cutting of pipes. Summary of the invention

[0004] The present invention provides a fiber laser cutting machine, which can load a plurality of pipes to be cut at the same time, and the plurality of pipes can be swung obliquely, so as to facilitate the oblique cutting of the pipes.

[0019] Optionally, the two ends of the loading member are rotatably connected to the inner ring body and the outer ring body through a connecting shaft respectively, and the connecting shaft close to the outer ring body passes through the outer ring body and is connected to the linkage assembly. A clamping assembly is provided on the loading member, and the clamping assembly includes a loading hole arranged on the loading member, and a plurality of elastic clamping members are provided in the loading hole.

Driven by the linkage assembly, the multiple workpieces may swing in at least two directions.

[0028] 3.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 3 As shown, this embodiment provides a fiber laser cutting machine, including a frame body 100, a pushing mechanism 200 is provided on one side of the frame body 100, the pushing mechanism 200 drives and connects one side of a multi-station reversing loading mechanism 300 slidably arranged on the frame body 100, and the other side of the multi-station reversing loading mechanism 300 is provided with a laser cutting mechanism 400 installed on the frame body 100.

[0037] The basic principle of this embodiment: the frame body 100 serves as a carrier of the equipment, and is used to load various mechanisms, wherein the pushing mechanism 200 can push the multi-station reversing device mechanism to gradually approach the laser cutting mechanism 400, and gradually cut multiple tubular pipes, wherein the multi-station reversing loading mechanism 300 can load multiple workpieces at the same time, and can drive multiple workpieces to rotate, so as to facilitate the laser cutting mechanism 400 to perform oblique cutting, wherein the multi-station reversing loading mechanism 300 can also push multiple workpieces intermittently toward the laser cutting mechanism 400.

[0038] In this embodiment, the multi-station reversing loading mechanism 300 is slidably connected to the frame body 100 through a sliding assembly. The above arrangement facilitates the directional sliding of the station reversing loading mechanism on the frame body 100 under the push of the pushing mechanism 200, so that the multi-station reversing loading mechanism 300 clamping the workpiece gradually approaches the laser cutting mechanism 400 for cutting by the laser cutting mechanism 400.

[0039] The sliding component is arranged in a wedge-shaped groove 110 on the frame body 100, and the multi-station reversing loading mechanism 300 includes a mounting body 310 slidably arranged on the frame body 100, and a wedge block 320 cooperating with the wedge-shaped groove 110 is arranged at the lower part of the mounting body 310, and a limit block 330 for limiting the mounting body 310 is arranged at the end of the wedge-shaped groove 110 close to the laser cutting mechanism 400.

[0040] The setting of the wedge groove 110 and the wedge block 320 can limit the mounting body 310 so that it can slide in a directional manner on the frame body 100, wherein the limit block 330 is used to limit the moving position of the mounting body 310. When the position of the mounting body 310 is limited, the subsequent pushing mechanism 200 can push multiple workpieces to continue to move toward the laser cutting mechanism 400 to cut different parts of the workpieces.

When the installation body 310 stops moving due to the blocking effect of the limit block 330, the telescopic pushing assembly can also push multiple workpieces continuously to the laser cutting mechanism 400 under the push of the electric push cylinder, so as to facilitate cutting of multiple positions of the workpiece.

[0045] The telescopic pushing assembly includes a pushing plate 220 connected to the pushing power member 210 and a telescopic rod 230 connected to the pushing plate 220. The telescopic rod 230 is sleeved with a spring 240, one end of the spring 240 is connected to the side of the mounting body 310, and the other end of the spring 240 is connected to the pushing plate 220.

The mounting body 310 moves to the limit block 330 under the drive of the pushing power member 210, and the mounting body 310 no longer moves. At this time, the pushing power member 210 can push the pushing plate 220 to move by continuing to compress the spring 240 and the telescopic rod 230, so that the pushing plate 220 can push the multiple workpieces to move toward the laser cutting mechanism 400 to cut multiple parts of the workpieces.
