DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-5, the present invention provides a technical solution: an automated processing device for stainless steel pipes with a deviation compensation function, including: a machine base 1, an automated cutting machine 3, and a pipe rack 9. A maintenance door 2 is provided on the surface of the machine base 1, and the maintenance door 2 can rotate, so as to facilitate opening the inside of the machine base 1, which is convenient for daily maintenance and repair of the equipment installed inside the machine base 1. An automated cutting machine 3 is installed on the top of the machine base 1, and the automated cutting machine 3 can move up and down, facilitating rapid cutting of pipes. The pipe rack 9 is in an "L" shape, and there are two pipe racks 9, and the two pipe racks 9 are symmetrically distributed about the longitudinal center line of the machine base 1. The pipe rack 9 can be used for racking pipes. A controller 21 is also installed on the surface of the machine base 1. The controller 21 can control the movement and rotation speed of the automated cutting machine 3, and can also control the operation of the displacement sensor 4, the DDC camera 5, the first hydraulic rod 7, the second hydraulic rod 8, and the booster pump 17. A displacement sensor 4 is installed on the side of the automated cutting machine 3, and the displacement sensor 4 can detect the offset position of the pipe. DDC cameras 5 are installed at both ends of the machine base 1, and the DDC cameras 5 can detect the cross-sectional center deviation value and the angle deviation value of the pipe. The displacement center base point of the displacement sensor 4, the cutting point of the automated cutting machine 3, and the irradiation base points of the two DDC cameras 5 are on the same straight line. Two fixing plates 6 are vertically connected to the surface of the machine base 1. The pipe rack 9 is slidably connected to the fixing plates 6 and the machine base 1 through an adjustment assembly. The adjustment assembly includes: a first hydraulic rod 7, a second hydraulic rod 8, a first chute 22, a second chute 23, and a connecting slider 24. A first hydraulic rod 7 is installed inside the machine base 1, and second hydraulic rods 8 are installed on the surfaces of the two fixing plates 6. The output ends of the first hydraulic rod 7 and the second hydraulic rod 8 are fixedly connected with a connecting slider 24. A first chute 22 is provided on the bottom surface of the pipe rack 9, and a second chute 23 is provided on the side surface of the pipe rack 9. The output end of the first hydraulic rod 7 passes through the inside of the machine base 1 and is slidably connected to the pipe rack 9 through the connecting slider 24 and the first chute 22. The output end of the second hydraulic rod 8 passes through the inside of the fixing plate 6 and is slidably connected to the pipe rack 9 through the connecting slider 24 and the second chute 23. When the first hydraulic rod 7 expands and contracts, it can drive the pipe rack 9 to move up and down. When the second hydraulic rod 8 moves, it can adjust the left and right position of the pipe rack 9. The pipe rack 9 also clamps the pipe through a clamping mechanism. The clamping mechanism includes: a clamping plate 10, a connecting block 11, an anti-slip pad 12, a lead screw 13, a bearing 14, and an adjustment disc 25. A clamping plate 10 is slidably connected to the surface of the pipe rack 9. The bottom of the clamping plate 10 is fixedly connected with a connecting block 11. Anti-slip pads 12 are adhered to the surface of the pipe rack 9 and the surface of the clamping plate 10. The anti-slip pad 12 is made of rubber. The anti-slip pad 12 can increase the friction between the clamping plate 10 and the pipe, so that the pipe is not easily offset when being clamped. A lead screw 13 is inserted through one end of the pipe rack 9. One end of the lead screw 13 is connected with a bearing 14, and an adjustment disc 25 is installed at the other end of the lead screw 13 away from the bearing 14. The lead screw 13 is rotatably connected to the pipe rack 9 through the bearing 14,The lead screw 13 also threadedly penetrates through the inside of the connecting block 11. When the operator rotates the adjusting disc 25, the lead screw 13 can be driven to rotate. Through the threaded connection between the lead screw 13 and the connecting block 11, the clamping plate 10 can move on the surface of the pipe rack 9, so as to facilitate the stable clamping of pipes of different sizes.,

[0026] Please refer to Figure 1 、 3 Inside the machine base 1, a circulating water tank 15 is provided. The circulating water tank 15 can be filled with coolant. A drain valve 16 that penetrates through the machine base 1 is provided on one side of the circulating water tank 15. The drain valve 16 can facilitate the discharge of the coolant inside the circulating water tank 15 for easy replacement. A booster pump 17 is also installed inside the circulating water tank 15. The booster pump 17 can press the coolant inside the circulating water tank 15 into the inside of the connecting pipe 18. The output end of the booster pump 17 is fixedly connected to the connecting pipe 18. The other end of the connecting pipe 18 is communicated with the cutting end of the automatic cutting machine 3. The pressed coolant can be sprayed on the cutting end of the automatic cutting machine 3. Thus, when the automatic cutting machine 3 cuts the pipe, the waste chips generated during cutting can be taken away, and at the same time, the generation of cutting sparks can be prevented to prevent the sparks from splashing and causing harm to the operator. Moreover, cooling the cutting can also improve the cutting efficiency of the blade of the automatic cutting machine 3 and the service life of the blade. Two symmetrical diversion grooves 19 are provided on the surface of the automatic cutting machine 3. The diversion grooves 19 can divert the dripping coolant into the circulating water tank 15. A water retaining strip 20 is fixedly connected around the opening end of the circulating water tank 15. The water retaining strip 20 can prevent the coolant from splashing on the surface of the machine base 1.,

[0027] Working principle: As Figures 1-5As shown, when using the automatic processing device for stainless steel pipes with the attached deviation compensation function, first, fill the coolant in the circulating water tank 15, then place the two ends of the stainless steel pipe on two pipe racks 9. By rotating the adjustment disc 25, the clamping plate 10 can clamp and fix the stainless steel pipe placed on the two pipe racks 9. Then start the controller 21, and make the controller 21 control the displacement sensor 4 and the DDC camera 5 to operate, so as to detect the placement of the pipe after clamping, the position during cutting, the deviation value of the cross-section center point and the angle deviation value. The detected data is transmitted into the controller 21. The controller 21 compares the data with the base data of the cutting end of the automatic cutting machine 3, the displacement sensor 4 and the DDC camera 5 to obtain the data difference, and then compensates the data difference by controlling the coordinated expansion and contraction of the first hydraulic rod 7 and the second hydraulic rod 8, so that the positions of the two pipe racks 9 can be adjusted in real time, thereby driving the pipes placed on the two pipe racks 9 to be adjusted in position in real time, so that the pipes are always in a stable state. Finally, start the automatic cutting machine 3 and the booster pump 17 through the controller 21. While the automatic cutting machine 3 precisely cuts the pipe, the coolant will continuously spray on the cutting blade of the automatic cutting machine 3, thereby reducing the cutting temperature of the cutting tool, improving the cutting efficiency and service life, preventing the generation of sparks during cutting, and the waste chips generated during cutting will also flow into the circulating water tank 15 with the coolant. By opening and closing the drain valve 16, it is convenient to replace the coolant regularly. This is the feature of the automatic processing device for stainless steel pipes with the attached deviation compensation function.
