[0043] The controller can automatically control the device elements.
[0044] Working principle:
[0045] In the pipe fixing device for laser cutting, the operator inserts the plug 7 on the arc plate 5 into the fixing port 11 of the clamping plate 4. During the movement of the plug 7, the fixing block 10 is compressed by the extrusion force to enter the installation port 8. When the plug 7 is completely inserted into the fixing port 11, the installation port 8 is opposite to the fixing port 11. The fixing block 10 is clamped into the fixing port 11 by the restoring force of the spring 9, and the simple installation and fixing of the arc plate 5 are completed. Conversely, the operator pulls the plug 7 out of the plug port 6 through the arc plate 5, and the fixing block 10 is automatically retracted to separate from the fixing port 11, and the simple disassembly of the arc plate 5 is completed. When processing the round pipe, the arc plate 5 can be simply installed. When processing the square pipe, the arc plate 5 can be simply disassembled.
[0046] When it is necessary to fix the pipe for laser cutting, first, the pipe is inserted through the through port 2 in the middle of the round plate 1, and then the electric push rod 3 is started at the same time. The output shaft of the electric push rod 3 drives the clamping plate 4 or the arc plate 5 to move towards the pipe until the clamping plate 4 tightly adheres to the surface of the pipe to fix the pipe. Then, the fixed pipe is cut by laser cutting.
[0047] The pipe fixing device for laser cutting significantly improves the clamping and fixing ability of the round pipe and the square pipe, ensures the stability of the pipe during laser cutting, improves the cutting precision and efficiency, and improves the product qualification rate, which has strong practicality.
[0048] The round plate 1 is provided with symmetrical electric push rods 3, clamping plates 4 and arc plates 5 on both sides. The electric push rod 3, the clamping plate 4 and the arc plate 5 on one side are arranged on the upper and lower sides of the round plate 1, and the electric push rod 3, the clamping plate 4 and the arc plate 5 on the other side are arranged on the left and right sides of the round plate 1. The pipe can be clamped from multiple directions at the same time, which enhances the stability and balance of clamping. Whether it is a round pipe or a square pipe, it can be uniformly and firmly fixed, effectively avoiding the instability caused by single-direction clamping, and improving the cutting stability.
[0049] The clamping plate 4 and the arc plate 5 are provided with rubber material pads on the surfaces. The rubber has good elasticity and friction. On the one hand, the elasticity can buffer the impact force generated when the clamping plate 4 and the arc plate 5 apply pressure to the pipe, avoiding damage to the surface of the pipe. On the other hand, the greater friction makes the pipe less likely to slide between the clamping plate 4 and the arc plate 5, further improving the stability of the pipe clamping and fixing, thereby further improving the cutting stability and ensuring the smooth progress of the cutting process.
[0050] When the pipe needs to be rotated and cut, the motor 13 is started, the gear disc 14 on the output shaft of the motor 13 is engaged with the outer gear ring 12, and the round plate 1 and the clamped pipe are driven to rotate, so that the pipe can be simply and easily cut at multiple angles, improving the cutting efficiency.
