[0037] See also Figure 1 One embodiment of the present invention provides a welding device. The welding device is used for welding workpieces.

[0038] The workpiece of this embodiment is a stainless steel thin-walled pipe, and the welding device is used to weld the annular joint of the stainless steel thin-walled pipe, and the welding device can prevent the pipe wall of the stainless steel thin-walled pipe from being deformed due to uneven heating during welding.

[0039] The welding device comprises a device body 1, a clamping mechanism, a welding mechanism and a protection mechanism.

[0040] The device body 1 has a working chamber, and the clamping mechanism, the welding mechanism, and the protection mechanism are all arranged in the working chamber.

[0041] The clamping mechanism is used to clamp and fix the workpiece to prevent the workpiece from being displaced during welding in the working chamber.

[0042] The welding mechanism is used for welding the workpieces.

[0043] See also Figure 2 The protection mechanism includes a telescopic member 34 and an adjustment assembly. The telescopic member 34 is arranged in an annular shape, and the adjustment assembly is used to drive the telescopic member 34 to extend and retract so that the outer wall of the telescopic member 34 is adapted to the workpiece.

[0044] The workpiece is sleeved outside the telescopic member 34 .

[0045] It can be understood that the outer wall of the telescopic member 34 is adapted to the workpiece, which means that the outer wall of the telescopic member 34 is closely attached to the inner wall of the stainless steel thin-walled pipe to support the stainless steel thin-walled pipe. At this time, the central axis of the annular telescopic member 34 coincides with the central axis of the stainless steel thin-walled pipe.

[0046] The welding device of this embodiment can drive the telescopic part 34 to extend and retract through the adjustment component, so that the outer wall of the telescopic part 34 is adapted to the workpiece, so that the telescopic part 34 fills the inner wall of the workpiece, which can play a supporting role for the workpiece, thereby preventing the workpiece from being deformed due to uneven heating during welding, thereby ensuring the quality of the product.

[0047] In some embodiments, the adjustment component includes a telescopic rod 14, a movable gear 30 and two movable racks 29, the telescopic rod 14 is arranged in the working chamber, the movable gear 30 is rotatably arranged on the telescopic rod 14, the two movable racks 29 are respectively arranged on opposite sides of the movable gear 30, and the two movable racks 29 are respectively engaged with the movable gear 30, one end of each movable rack 29 is connected to the inner wall of the telescopic member 34, and the telescopic member 34 is provided with a retractable telescopic part 33.

[0048] When in use, the operator rotates the movable gear 30 to drive the two movable racks 29 to move in opposite directions to push the telescopic member 34 to expand and contract, so that the telescopic member 34 can fully support the inner wall of the workpiece, which can play a supporting role on the workpiece, thereby preventing the workpiece from being deformed due to uneven heating during welding, thereby ensuring the quality of the product. In this process, the telescopic portion 33 expands and contracts to adapt to the shape and size changes of the telescopic member 34.

[0049] In some embodiments, the upper outer surface of the device body 1 is fixedly connected to the limiting base 7 , and the telescopic rod 14 is inserted through the limiting base 7 .

[0051] Furthermore, the two support blocks 31 are arranged in opposite directions.

[0052] When the movable gear 30 drives the two movable racks 29 to move in opposite directions, the two support blocks 31 can move in opposite directions to push the telescopic member 34 to extend and retract, thereby increasing the outer diameter of the telescopic member 34 and allowing the telescopic member 34 to fully support the inner wall of the workpiece.

[0053] During the welding process, the support block 31 supports the inner wall of the workpiece through the telescopic member 34 to prevent the workpiece from deforming.

[0054] In some embodiments, the protection mechanism further includes a gear handle 32 , and the gear handle 32 is disposed on the movable gear 30 .

The two movable rods 15 are respectively connected to the two driving gears 16, and the two clamping plates 13 are respectively connected to the two movable rods 15.

[0056] When in use, the operator rotates the movable worm 17 to move the two driving gears 16, driving the corresponding movable rods 15 to rotate in opposite directions, thereby driving the two clamping plates 13 to contract or expand, so that the two clamping plates 13 contract toward the center to clamp and fix the workpiece.

[0057] Optionally, a handle is provided at one end of the movable worm 17, and an operator manually rotates the handle to drive the movable worm 17 to rotate, so that drive adjustment can be performed conveniently and quickly.

[0058] In some embodiments, two opposite sides of the two clamping plates 13 are provided with anti-skid layers 21. When the two clamping plates 13 are retracted toward the center, the anti-skid layers 21 can better fix the workpiece and improve the reliability of the clamping mechanism.

[0059] In some embodiments, the clamping mechanism further includes a gear base 19 and two gear rods 20, the two gear rods 20 are respectively disposed on the gear base 19, and the two driving gears 16 are respectively and correspondingly rotatably sleeved on the two gear rods 20. In some embodiments, the movable worm 17 is disposed in the gear base 19, and a limit baffle 18 is provided at one end of the movable worm 17.

[0060] The limit baffle 18 cooperates with the inner wall of the gear base 19 to limit the moving distance of the movable worm 17 in the gear base 19 , thereby preventing the movable worm 17 from being separated from the two driving gears 16 .

[0061] In some embodiments, see Figure 1 and Figure 4The welding mechanism includes a fixed base 11, a fixed gear 35, an adjusting gear 37, a fixed screw 39, a lifting box 38 and a welding body 43.

[0062] When in use, the operator rotates the adjusting gear 37 to drive the fixed gear 35 to move, and then the lifting box 38 is ordered to move up and down under the action of the fixed screw 39, so as to adjust to a suitable height for welding the workpiece, making the welding result more accurate and ensuring the quality of the product.

[0063] In some embodiments, the welding mechanism further includes an adjusting handle 36 , and the adjusting handle 36 is connected to the adjusting gear 37 . An operator can drive the adjusting gear 37 to rotate in the fixed base 11 through the adjusting handle 36 .
