Description

Technical Field

[0001] This utility model belongs to the technical field of welding auxiliary devices, specifically a welding auxiliary device for stainless steel profiles. Background Technology

[0002] There are many types of stainless steel profiles, and many stainless steel products require welding during processing. For example, when producing barrel-shaped stainless steel products (stainless steel trash cans, stainless steel food containers, etc.), the cut stainless steel sheets need to be rolled into a barrel shape and then welded. After the barrel shape is formed, the bottom plate also needs to be welded. Current welding methods are not convenient for limiting the position of stainless steel sheets, nor for splicing and limiting the semi-finished stainless steel barrels and bottom covers, which affects the accuracy of welding and the convenience of operation. Therefore, this application proposes a stainless steel profile welding auxiliary device. Utility Model Content

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0020] In use, the cut stainless steel sheet is first rolled into a barrel shape. Then, the barrel shape is pressed and fixed by the rotating support mechanism 2 and the pressing mechanism 3. Then, the lifting drive mechanism 5 drives the welding gun 6 to move up and down. The welding gun 6 is used to weld the vertical splice seam on the side of the barrel. After welding, the pressing mechanism 3 is raised a certain distance and the bottom cover is placed on the top of the welded barrel. The pressing mechanism 3 is pressed down again to limit the position and drive the barrel and the bottom cover to rotate synchronously. At this time, the welding gun 6 is adjusted to the specified height and the annular splice seam between the barrel and the bottom cover is welded by the welding gun 6.

[0021] The rotating support mechanism 2 consists of a servo motor 7, a drive gear 8, a rotating support chassis 9, and an external gear ring 10. The servo motor 7 is fixedly connected to the side of the bottom inside the support frame 1. The drive gear 8 is fixedly connected to the output shaft of the servo motor 7. The rotating support chassis 9 is rotatably connected to the bottom inside the support frame 1. The external gear ring 10 is fixedly connected to the top of the arc-shaped outer surface of the rotating support chassis 9 and meshes with the drive gear 8.

[0022] When the rotating support mechanism 2 is working, the servo motor 7 drives the drive gear 8 to rotate, the drive gear 8 drives the outer gear ring 10 to rotate, and the outer gear ring 10 drives the rotating support chassis 9 to rotate.

[0023] The pressing mechanism 3 consists of a hydraulic rod 11 and a pressing plate 12. The hydraulic rod 11 is inserted through the middle of the top of the support frame 1 and is fixedly connected to the support frame 1. The pressing plate 12 is rotatably connected to the bottom of the hydraulic rod 11. The top of the rotating support base 9 and the bottom of the pressing plate 12 are provided with three annular limiting slots 13 of different diameters.

[0024] The hydraulic rod 11 can drive the lower pressure plate 12 to be raised and lowered.

[0025] The rotating support chassis 9 is rotatably connected to the support frame 1 via bearing 14. A sleeve 15 is fixedly installed at the middle position of the top of the lower pressure plate 12. The sleeve 15 is sleeved on the bottom end of the hydraulic rod 11 and rotatably connected to it via bearing 16.

The second servo motor 17 is fixedly connected to the side of the top of the support frame 1. The lead screw 18 is rotatably connected to the inside of the vertical slide groove 4 and is fixedly connected to the output shaft of the second servo motor 17. The limiting support slide 19 is slidably connected to the inside of the vertical slide groove 4. The limiting support slide 19 is sleeved on the lead screw 18 and threadedly connected to the lead screw 18.

[0028] Servo motor 17 drives lead screw 18 to rotate, and lead screw 18 drives limit support slide 19 to rise and fall, thereby enabling welding of the vertical splice seam of the barrel body, and at the same time aligning the splice seam of the barrel body and the bottom cover.

[0029] The limiting support slide 19 has an internal mounting groove 20 that matches the welding gun 6. The mounting groove 20 is offset from the lead screw 18. A locking bolt 21 that matches the welding gun 6 is inserted at one end of the top of the limiting support slide 19. The locking bolt 21 is threadedly connected to the limiting support slide 19.

[0030] The mounting slot 20 can be used to install and fix the welding gun 6. The mounting slot 20 and the lead screw 18 are offset to avoid mutual interference. The locking bolt 21 can lock and limit the welding gun 6, thereby improving the stability of the welding gun 6.
