Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a fiber laser tube cutting machine connected with a lifting arm. Background Art

[0002] Fiber laser tube cutting machine is a device specially used to cut metal tubes. It uses laser technology to achieve high-speed and precise cutting. This machine uses fiber laser as a cutting tool, and has the characteristics of fast cutting speed, smooth incision and high precision. Fiber laser tube cutting machine is widely used in the metal processing industry, which can improve production efficiency, reduce energy consumption, and also reduce the difficulty and safety risks of manual operation.

[0003] When cutting pipes, existing fiber laser tube cutting machines require workers to move the pipes to the cutting position of the fiber laser cutting machine, which is cumbersome to operate. In addition, the fiber laser cutting machines are mostly fixed and cannot quickly cut different positions of the pipes. The fiber laser cutting machine has low tube cutting efficiency. Therefore, we propose a fiber laser tube cutting machine connected to a lifting arm. Utility Model Content

[0004] The purpose of the utility model is to provide a fiber laser tube cutting machine connected with a lifting arm to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fiber laser tube cutting machine connected to a lifting arm comprises a workbench and a fiber laser cutting machine, a conveyor belt is installed on the workbench, vertical plates are connected to the left end of the upper surface of the workbench and at both sides of the front and rear of the conveyor belt, a mounting plate is provided between adjacent vertical plates, an electric hydraulic rod is connected to the top of the mounting plate, and a lifting arm is installed at the telescopic end of the electric hydraulic rod, a top beam is provided on the lower surface of the lifting arm, a U-shaped frame is slidably connected to the bottom of the top beam, and the bottom of the U-shaped frame is connected to the fiber laser cutting machine, side vertical plates are provided on the upper surface of the workbench and at both ends of the conveyor belt, electric push rods are connected to the outer walls of the two sets of side vertical plates, and limit plates are provided at the telescopic ends of the electric push rods.

[0007] Furthermore: the open end of the U-shaped frame faces the lower surface of the top beam, and a stepper motor is installed on the left outer wall of the U-shaped frame, the output end of the stepper motor is connected to a drive shaft, a rotating gear is sleeved on the drive shaft, and multiple sets of meshing grooves are opened at the bottom of the top beam, and the rotating gear is meshed and connected with the multiple sets of meshing grooves.

[0008] Furthermore: a T-shaped slot is provided on the right side wall of the top beam, a T-shaped block is slidably connected in the T-shaped slot, and a linkage rod is provided on the outer wall of the T-shaped block, and the bottom end of the linkage rod is connected to the right side outer wall of the U-shaped frame.

[0010] Furthermore: a damping pad is bonded to the inner side surface of the limiting plate, and a corrugated protrusion is embedded on the outer surface of the damping pad.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model can drive the lifting arm to move up and down through the electric hydraulic rod, and the operation of the stepping motor can drive the rotating gear on the driving shaft to rotate forward or reverse. Since the rotating gear is meshed and connected with multiple groups of meshing grooves, and the U-shaped frame is limited by the sliding of the linkage rod, the T-block and the T-slot, the U-shaped frame can drive the fiber optic laser cutting machine at the bottom to move forward and backward to adjust the position, and can quickly cut different front and rear positions of the pipe transmitted from the conveyor belt, effectively improving the pipe cutting efficiency; through the operation of the two groups of electric push rods, the limit plate can be driven to move, and the pipe in the cutting process can be limited, thereby improving the accuracy of the pipe cutting position.
