Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically to a stainless steel pipe end ring welding machine. Background Technology

[0002] The stainless steel pipe end circumferential welding machine is a device specifically designed for welding the circumferential weld seam at the end of stainless steel pipes. It is an indispensable piece of equipment in the stainless steel pipe processing process.

[0003] A search revealed that patent document CN114952171A discloses a tooling fixture device for a stainless steel pipe circumferential welding machine. This device, consisting of a machine body, transmission screw, base plate, power mechanism, servo motor, linear bidirectional drive mechanism, support base, pressing seat, limiting device, clamping device, slot, and anti-slip protrusions, places the stainless steel pipe to be welded onto the support base. The linear bidirectional drive mechanism drives the support base and pressing seat. V-shaped notches are provided at the top center of the support base and the bottom center of the pressing seat to accommodate pipes of different diameters. The limiting device, in conjunction with the slot, ensures good stability when clamping the support base and pressing seat. The interaction force between them further enhances the clamping of the pipe, resulting in a secure and stable clamping of the pipe, reducing the impact of external forces or vibrations, preventing loosening or slippage, ensuring safety and reliability, and improving work efficiency and performance.

[0004] However, during the welding process, when the stainless steel pipe needs to be replaced, the clamp needs to be opened and closed, which consumes operation time. At the same time, the stainless steel pipe cannot be assisted in feeding during the automatic welding process, which reduces welding efficiency. Utility Model Content

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a stainless steel pipe end ring welding machine.

[0027] This utility model provides, for example Figure 1-3 The stainless steel pipe end ring welding machine shown includes a frame 1, a welding mechanism 2 and a clamping chuck 3 disposed inside the frame 1, and a welding machine 4. The machine is characterized in that a clamp frame 5 is provided on the top of the frame 1, a rotating hole is provided on the side of the clamp frame 5, a support rod 6 is fixedly provided in the rotating hole, a shifting clamp 7 is rotatably sleeved on the wall of the support rod 6, a shifting clamping mechanism is provided at the end of the shifting clamp 7 for limiting the position of the shifting clamp 7, a base 8 is provided at the bottom of the clamp frame 5, the base 8 is fixedly connected to the frame 1, and an auxiliary adjustment mechanism is provided inside for adjusting the position of the clamp frame 5.

[0028] Before welding the end rings of the stainless steel pipes, two stainless steel pipes are arranged vertically within the clamp frame 5 and positioned on both sides of the transposition clamping plate 7. With the support of the support rod 6, the transposition clamping plate 7 is raised to clamp the upper stainless steel pipe. The other end of the upper stainless steel pipe is then positioned in the clamping chuck 3, ensuring stable welding. After welding the upper stainless steel pipe, the transposition clamping plate 7 is reversed to clamp the lower stainless steel pipe. The upper stainless steel pipe can then be directly removed, reducing the time for loading and unloading stainless steel pipes and improving welding efficiency. Furthermore, during the welding process, another stainless steel pipe can be inserted into the clamp frame 5 to ensure continuous pipe loading, further improving welding efficiency.

[0029] In order to fix the position of the transposition clamp 7 during its rotation and to stably clamp the stainless steel tube, such as Figure 2-3 As shown, the shifting clamping mechanism includes a fixed plate 9, which is fixedly installed on the outer wall of the clamp frame 5, and a plurality of stop bars 10 are fixedly installed on its surface in a symmetrical arrangement around the axis of the support rod 6. A U-shaped plate 11 is fixedly installed at the lower end of the shifting clamping plate 7, and a locking plate 12 is installed inside the U-shaped plate 11. The locking plate 12 is engaged between two adjacent stop bars 10.

[0030] A fixing rod 13 is fixedly installed inside the card plate 12. The rod wall of the fixing rod 13 is rotatably inserted through the side of the U-shaped plate 11. A torsion spring 14 is sleeved on the rod wall of the fixing rod 13. The two ends of the torsion spring 14 are fixedly connected to the fixing rod 13 and the U-shaped plate 11 respectively.

[0031] Before rotating the shift clamp 7, the clamping plate 12 can be rotated so that the clamping plate 12 rotates within the U-shaped plate 11 under the cooperation of the torsion spring 14 of the fixing rod 13 and moves away from the stop rod 10. After the clamping plate 12 drives the shift clamp 7 to rotate around the support rod 6 and clamps the stainless steel tube, the clamping plate 12 is released. The torsion spring 14 returns to its original position, causing the clamping plate 12 to engage between two adjacent stop rods 10. This completes the fixation of the positions of the clamping plate 12 and the shift clamp 7, so that the stainless steel tube can be stably clamped.

[0032] In order to adjust the height of the stainless steel tubes after switching between the upper and lower stainless steel tubes and to ensure stable engagement with the clamping chuck 3, such as... Figure 1-2As shown, the auxiliary adjustment mechanism includes an electric push rod 15, which is located inside the base 8. A push block 16 is fixedly provided at the end of the output shaft. A groove is provided on the inner wall of the base 8, and the electric push rod 15 is fixedly provided in the groove. A movable block 17 is fixedly provided at the bottom of the clamp frame 5. The movable block 17 slides through the bottom of the base 8, and the lower end of its side wall contacts and engages with the push block 16. The contact side of the push block 16 and the movable block 17 is set with an inclined surface. A guide rod 18 is fixedly provided at the bottom of the clamp frame 5, and the guide rod 18 slides inside the base 8.

[0033] When the stainless steel pipe below is clamped and welding is required, the electric push rod 15 can be activated to push the push block 16. When the inclined surface of the push block 16 and the moving block 17 is pushed, the moving block 17 drives the fixture frame 5 to move longitudinally, thereby precisely adjusting the height position of the fixture frame 5 and the stainless steel pipe, so that the other end of the stainless steel pipe can be stably matched with the clamping chuck 3 to complete the stable welding.

[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
