[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figure 1 - Figure 9 , a production device for a refrigeration compressor housing, including a welding torch main body 1 and a welding torch barrel 2, a welding torch head 3 is provided at one end of the welding torch barrel 2, and further includes:

[0032] A bent pipe 6, the bent pipe 6 is fixedly connected to the top end of the welding torch barrel 2, and an angle adjustment assembly for driving the bent pipe 6 to rotate to adjust the inclination angle of the welding torch barrel 2 is provided in the welding torch main body 1;

[0033] Connect the bent pipe 10. The bottom end of the connecting bent pipe 10 is arranged at the top end of the elbow pipe 6, and the top end of the connecting bent pipe 10 is provided with a connecting pipe body 11 that slides within the welding torch body 1;

[0034] During use, when it is necessary to insert the welding torch body 1 into the shell for welding, the elbow pipe 6 is driven to rotate by the angle adjustment assembly. The elbow pipe 6 can drive the welding torch pipe body 2 and the welding torch head 3 to rotate, adjusting the inclination angle of the welding torch head 3 so that the welding torch head 3 inserted into the shell can be aligned with the welding position to be welded for welding. Structures such as the wire feeding pipe are arranged within the welding torch pipe body 2, the elbow pipe 6, the connecting bent pipe 10, and the connecting pipe body 11. Because it is necessary to adjust the inclination angle of the welding torch head 3 and also prevent the internal structures such as the wire feeding pipe from being overly bent. An overly bent wire feeding pipe increases the friction between the welding wire and the welding torch head 3, resulting in poor wire feeding. By providing the connecting bent pipe 10, it is possible to prevent the structures such as the wire feeding pipe from being overly bent.

[0035] Refer to Figure 2 and Figure 3 As shown in, the angle adjustment assembly includes a first motor 4 fixedly connected within the welding torch body 1. The output shaft of the first motor 4 is fixedly connected with a first gear 5. An outer wall of the elbow pipe 6 is fixedly connected with a first arc-shaped rack 7 that meshes with the first gear 5. An outer wall of the elbow pipe 6 is fixedly connected with a connecting column 8. One end of the connecting column 8 is fixedly connected with a first rotating shaft 9. The first rotating shaft 9 is rotatably connected to an inner wall of the welding torch body 1; When it is necessary to adjust the inclination angle of the welding torch head 3, start the first motor 4. The first motor 4 drives the first gear 5 to rotate. The first gear 5 drives the first arc-shaped rack 7 and the elbow pipe 6 to rotate around the first rotating shaft 9. The elbow pipe 6 drives the welding torch pipe body 2 and the welding torch head 3 to rotate, achieving the purpose of adjusting the angle of the welding torch head 3.

[0036] Refer to Figure 3 and Figure 4, the elbow 6 and the connecting bent pipe 10 are both quarter arcs. The connecting bent pipe 10 includes multiple short pipe bodies connected end to end. The short pipe body includes an arc-shaped pipe body 1001, a metal hose 1002, and a rotating ring 1003. The arc-shaped pipe body 1001 is fixedly connected to the adjacent metal hose 1002. The metal hose 1002 is fixedly connected to the adjacent rotating ring 1003. The rotating ring 1003 is rotatably connected to the adjacent arc-shaped pipe body 1001. The lowermost and uppermost rotating rings 1003 are respectively rotatably connected to one end of the elbow 6 and one end of the connecting pipe body 11. When it is necessary to adjust the welding torch head 3 to a larger angle to meet the welding requirements at different angles, a certain number of arc-shaped pipe bodies 1001 close to the elbow 6 are rotated 180 degrees. The rotating ring 1003 rotates on the adjacent arc-shaped pipe body 1001, and the metal hose 1002 is compressed during rotation to prevent interference with the rotation of the arc-shaped pipe body 1001. After the rotation of the arc-shaped pipe body 1001 is completed, it will be spliced with the elbow 6 to form an arc. The first motor 4 can drive the welding torch head 3 to rotate at a larger angle through the spliced arc-shaped pipe body 1001. By setting the connecting bent pipe 10 and the elbow 6 with a quarter arc, if all the arc-shaped pipe bodies 1001 of the connecting bent pipe 10 are rotated 180 degrees, the elbow 6 and the connecting bent pipe 10 form a semi-circle, so that the welding torch head 3 can be adjusted to rotate between 0 - 180 degrees to meet different welding requirements. By setting the connecting bent pipe 10 that can be rotated in segments, the structures such as the wire feeding pipe inside it can be prevented from being overly bent. If the semi-circle is directly connected to the connecting pipe body 11, the wire feeding pipe will be overly bent, affecting the wire feeding.

[0037] Refer to Figure 3 , Figure 4 , Figure 5 and Figure 7 , the outer walls of the arc-shaped pipe bodies 1001 are fixedly connected with second arc-shaped racks 12. The second arc-shaped racks 12 are fixedly connected with connecting wires 13. One end of the connecting wire 13 is fixedly connected with a wire winding wheel 14. The inner wall of the wire winding wheel 14 is fixedly connected with a second rotating shaft 15. The connecting pipe body 11 is fixedly connected with an arc-shaped block 16 through a cross bar. Multiple second rotating shafts 15 are rotatably connected to the arc-shaped block 16. When it is necessary to adjust the welding torch head 3 to a larger angle, a certain number of arc-shaped pipe bodies 1001 close to the elbow 6 are rotated. The arc-shaped pipe body 1001 drives the second arc-shaped rack 12 to rotate. The second arc-shaped rack 12 and the first arc-shaped rack 7 form a continuous arc. The first motor 4 can drive the elbow 6 and the welding torch head 3 to rotate at a larger angle through the first gear 5, the first arc-shaped rack 7, and the rotated second arc-shaped rack 12.

[0038] Refer to Figure 3 , Figure 5 , Figure 6 and Figure 7, a second gear 18 is slidably connected to the outer wall of the second rotating shaft 15 through a chute and a sliding bar. A second motor 36 is fixedly connected to the inner wall of the welding torch main body 1. An output shaft of the second motor 36 is fixedly connected to a third rotating shaft 37. The third rotating shaft 37 is rotatably connected to the welding torch main body 1. A connecting rod 38 is fixedly connected to the outer wall of the third rotating shaft 37. One end of the connecting rod 38 is fixedly connected to a third arc-shaped rack 39. The second gear 18 can move towards the wire reel 14 and mesh with the third arc-shaped rack 39; when it is necessary to rotate a certain number of arc-shaped pipe bodies 1001 close to the elbow 6, make the corresponding number of second gears 18 move towards the wire reel 14, make the second gear 18 mesh with the third arc-shaped rack 39, start the second motor 36 to drive the third rotating shaft 37 to rotate. The third rotating shaft 37 drives the third arc-shaped rack 39 to rotate through the connecting rod 38. The third arc-shaped rack 39 drives the engaged second gear 18 to rotate. The second gear 18 drives the second rotating shaft 15 to rotate. The second rotating shaft 15 drives the wire reel 14 to rotate. The wire reel 14 winds the connecting wire 13 onto its surface. The wire reel 14 pulls the second arc-shaped rack 12 and the arc-shaped pipe body 1001 to rotate through the connecting wire 13, so that the second arc-shaped rack 12 and the first arc-shaped rack 7 are spliced into a continuous arc, so that the welding torch head 3 rotates through a larger angle. If it is necessary to reset the arc-shaped pipe body 1001 and the second arc-shaped rack 12, just make the second gear 18 move away from the wire reel 14, so that the second gear 18 does not mesh with the third arc-shaped rack 39. Under the action of the gravity of the second arc-shaped rack 12, the arc-shaped pipe body 1001 and the second arc-shaped rack 12 are reset.

[0039] Refer to Figure 6 and Figure 7 , a spring 17 is fixedly connected between the wire reel 14 and the second gear 18. A plurality of sliding rods 20 are slidably inserted into the arc-shaped block 16. One end of the sliding rod 20 is fixedly connected to a top ring 19. The top ring 19 abuts against the side wall of the second gear 18. The other end of the sliding rod 20 is fixedly connected to an iron block 21. A plurality of electromagnets 22 corresponding to the iron blocks 21 are fixedly connected to the arc-shaped block 16; when it is necessary to make the second gear 18 move towards the wire reel 14, turn on the corresponding electromagnet 22. The electromagnet 22 is energized to generate a magnetic force to attract the iron block 21 to move. The iron block 21 drives the top ring 19 to move through the sliding rod 20. The top ring 19 can push the second gear 18 to move, so that the second gear 18 moves towards the wire reel 14 and meshes with the third arc-shaped rack 39, so that the arc-shaped pipe body 1001 and the second arc-shaped rack 12 can rotate.

[0040] Refer to Figure 1 , Figure 2 and Figure 8, the welding torch body 2 includes a first pipe body 201, a second pipe body 202 and a third pipe body 203. A metal bellows 23 is fixedly connected between the first pipe body 201 and the second pipe body 202. A connecting block 24 is fixedly connected to the outer wall of the second pipe body 202. A connecting rod 25 is rotatably connected to the connecting block 24. The top of the connecting rod 25 is fixedly connected with a lifting ring 26. A first fixing sleeve 27 is fixedly connected to the outer wall of the first pipe body 201. The lifting ring 26 is slidably connected to the outer wall of the first fixing sleeve 27. Two first mounting holes 28 are formed in the outer wall of the first fixing sleeve 27. The lifting ring 26 is fixed at the lower first mounting hole 28 through a first fastener 29. When it is necessary to slightly adjust the inclination angle of the welding torch head 3, the first fastener 29 is removed to make the lifting ring 26 move upward. The lifting ring 26 drives the second pipe body 202 to rotate around the metal bellows 23 through the connecting rod 25 and the connecting block 24, so that the second pipe body 202 and the welding torch head 3 are slightly bent to meet the welding requirements at a small angle. Then the lifting ring 26 is fixed at the upper first mounting hole 28 through the first fastener 29.

[0041] Refer to Figure 2 and Figure 9 , the first pipe body 201 and the third pipe body 203 are rotatably connected. A rotating block 30 is fixedly connected to the outer wall of the first pipe body 201. The top of the rotating block 30 is fixedly connected with a mounting plate 33. A second fixing sleeve 31 is fixedly connected to the outer wall of the third pipe body 203. A plurality of second mounting holes 32 are formed in the outer wall of the second fixing sleeve 31. The mounting plate 33 is fixed at one of the second mounting holes 32 through a second fastener 34. When it is necessary to adjust the azimuth angle of the welding torch head 3 to meet different welding requirements, the second fastener 34 is removed, and the first pipe body 201 can be rotated relative to the third pipe body 203. The first pipe body 201 drives the welding torch head 3 to rotate. After rotating to a suitable azimuth, the mounting plate 33 is fixed at the corresponding second mounting hole 32 through the second fastener 34.

[0042] Refer to Figure 1 and Figure 2 , a protection bracket 35 for preventing the welding torch head 3 from colliding with the inner wall of the housing is arranged on the welding torch head 3. By arranging the protection bracket 35, when the welding torch head 3 enters the housing, the protection bracket 35 can prevent the welding torch head 3 from colliding with the inner wall of the housing.

[0043] Working principle: When in use, when it is necessary to extend the welding torch body 1 into the shell for welding, the elbow 6 is driven to rotate by the angle adjustment component. The elbow 6 can drive the welding torch tube body 2 and the welding torch head 3 to rotate, adjusting the inclination angle of the welding torch head 3 so that the welding torch head 3 extending into the shell can be aligned with the welding position to be welded. Structures such as the wire feeding tube are arranged in the welding torch tube body 2, the elbow 6, the connecting bent tube 10 and the connecting tube body 11. Because it is necessary to adjust the inclination angle of the welding torch head 3 and prevent the structures such as the internal wire feeding tube from being overly bent. An overly bent wire feeding tube increases the friction between the welding wire and the welding torch head 3, resulting in poor wire feeding. By setting the connecting bent tube 10, the structures such as the wire feeding tube can be prevented from being overly bent;

[0044] When it is necessary to adjust the inclination angle of the welding torch head 3, start the first motor 4. The first motor 4 drives the first gear 5 to rotate. The first gear 5 drives the first arc-shaped rack 7 and the elbow 6 to rotate around the first rotating shaft 9. The elbow 6 drives the welding torch tube body 2 and the welding torch head 3 to rotate, achieving the purpose of adjusting the angle of the welding torch head 3;

[0045] When it is necessary to adjust the welding torch head 3 to a larger angle to meet the welding requirements at different angles, a certain number of arc-shaped tube bodies 1001 close to the elbow 6 are rotated 180 degrees. The rotating ring 1003 rotates on the adjacent arc-shaped tube bodies 1001. The metal hose 1002 is compressed during rotation to prevent interference with the rotation of the arc-shaped tube bodies 1001. After the arc-shaped tube bodies 1001 are rotated, they will be spliced with the elbow 6 to form a circular arc. The first motor 4 can drive the welding torch head 3 to rotate at a larger angle through the spliced arc-shaped tube bodies 1001. And by setting the connecting bent tube 10 with a quarter-circle arc and the elbow 6, if all the arc-shaped tube bodies 1001 of the connecting bent tube 10 are rotated 180 degrees, the elbow 6 and the connecting bent tube 10 form a semi-circle arc, so that the welding torch head 3 can be adjusted to rotate between 0 - 180 degrees to meet different welding requirements. By setting the connecting bent tube 10 that can be rotated in segments, the structures such as the internal wire feeding tube can be prevented from being overly bent. If the semi-circle arc is directly connected to the connecting tube body 11, the wire feeding tube will be overly bent, affecting the feeding of the welding wire;

[0046] When it is necessary to make the welding torch head 3 rotate at a larger angle, a certain number of arc-shaped tube bodies 1001 close to the elbow 6 are rotated. The arc-shaped tube bodies 1001 drive the second arc-shaped rack 12 to rotate. The second arc-shaped rack 12 forms a continuous circular arc with the first arc-shaped rack 7. The first motor 4 can drive the elbow 6 and the welding torch head 3 to rotate at a larger angle through the first gear 5, the first arc-shaped rack 7 and the rotated second arc-shaped rack 12;

[0047] When it is necessary to rotate a certain number of arc-shaped pipe bodies 1001 close to the elbow 6, so that the corresponding number of second gears 18 move towards the wire winding wheel 14, making the second gear 18 engage with the third arc-shaped rack 39, start the second motor 36 to drive the third rotating shaft 37 to rotate. The third rotating shaft 37 drives the third arc-shaped rack 39 to rotate through the connecting rod 38. The third arc-shaped rack 39 drives the engaged second gear 18 to rotate. The second gear 18 drives the second rotating shaft 15 to rotate. The second rotating shaft 15 drives the wire winding wheel 14 to rotate. The wire winding wheel 14 winds the connecting wire 13 onto its surface. The wire winding wheel 14 pulls the second arc-shaped rack 12 and the arc-shaped pipe body 1001 to rotate through the connecting wire 13, making the second arc-shaped rack 12 and the first arc-shaped rack 7 form a continuous arc, so that the welding torch head 3 rotates a larger angle. If it is necessary to reset the arc-shaped pipe body 1001 and the second arc-shaped rack 12, just make the second gear 18 move away from the wire winding wheel 14, so that the second gear 18 does not engage with the third arc-shaped rack 39. Under the action of the gravity of the second arc-shaped rack 12, the arc-shaped pipe body 1001 and the second arc-shaped rack 12 are reset;

[0048] When it is necessary to make the second gear 18 move towards the wire winding wheel 14, turn on the corresponding electromagnet 22. The electromagnet 22 is energized to generate magnetic force to attract the iron block 21 to move. The iron block 21 drives the top ring 19 to move through the sliding rod 20. The top ring 19 can push the second gear 18 to move, making the second gear 18 move towards the wire winding wheel 14 to engage with the third arc-shaped rack 39, so that the arc-shaped pipe body 1001 and the second arc-shaped rack 12 can rotate;

[0049] When it is necessary to slightly adjust the tilt angle of the welding torch head 3, loosen the first fastener 29, make the lifting ring 26 move upward. The lifting ring 26 drives the second pipe body 202 to rotate around the metal bellows 23 through the connecting rod 25 and the connecting block 24, making the second pipe body 202 and the welding torch head 3 bend slightly to adapt to the welding requirements of small angles, and fix the lifting ring 26 at the upper first mounting hole 28 through the first fastener 29;

[0050] When it is necessary to adjust the azimuth angle of the welding torch head 3 to adapt to different welding requirements, loosen the second fastener 34, and the first pipe body 201 can rotate relative to the third pipe body 203. The first pipe body 201 drives the welding torch head 3 to rotate. After rotating to the appropriate azimuth, fix the mounting plate 33 at the corresponding second mounting hole 32 through the second fastener 34;

[0051] By setting the protection bracket 35, when the welding torch head 3 enters the shell, the protection bracket 35 can prevent the welding torch head 3 from colliding with the inner wall of the shell.

Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
