[0014] When welding the end of the copper bar rotor, rotate the bidirectional threaded rod, and the two nuts move into the threaded rod, causing the plate slider to slide towards the middle of the plate chute. At the same time, the block slider moves towards the middle of the block chute, and the two cross connecting rods on both sides move towards the middle of the block chute, reducing the crossing angle. The height of the placement plate is adjusted upwards so that the heating block can abut against the end ring and the copper bar to weld the end. After the welding of the end of the copper bar rotor is completed, rotate the bidirectional threaded rod in the reverse direction, causing the two nuts to move outwards of the threaded rod, making the plate slider slide towards both sides of the plate chute. At the same time, the block slider moves towards both sides of the block slider, and the two cross connecting rods on both sides move towards both sides of the block chute, increasing the crossing angle. The height of the placement plate is adjusted downwards so that the heating block no longer abuts against the end ring and the copper bar, completing the welding of the end.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following further details the present application with reference to the accompanying drawings.
[0021] Embodiment, referring to Figure 1 and Figure 2, An auxiliary adjustment device for welding the end of a copper bar rotor, including a support frame 2. There is a steering groove at the upper end of the support frame 2. A turntable 1 is rotatably connected in the steering groove. There is an installation hole 3 at the lower end of the steering groove. There are multiple circumferentially arrayed limiting tubes 19 in the turntable 1. Openings are provided at the corresponding positions of the turntable 1 and the multiple limiting tubes 19. The limiting tubes 19 and the installation hole 3 are located on the same circumference. At the middle position of the upper end of the turntable 1, there is a first steering column 28. The upper end of the first steering column 28 is rotatably connected to a fixing plate 20. A first spur gear 25 is fixedly installed near the fixing plate 20 on the first steering column 28. The lower end of the fixing plate 20 is rotatably connected to a first straight bevel gear 26. One side of the first spur gear 25 meshes with the first straight bevel gear 26.
[0022] At the middle position of the lower end of the support frame 2, a second steering column 7 is rotatably connected. A second spur gear 4 is fixedly installed near the support frame 2 on the second steering column 7. A second straight bevel gear 5 is rotatably connected to the lower end of the support frame 2. One side of the second straight bevel gear 5 meshes with the second spur gear 4. A fixing block 8 is fixedly installed at the lower end of the second steering column 7.
[0023] When welding the end of the copper bar rotor 9, the copper bar is placed into the limiting tube 19. The first straight bevel gear 26 rotates. The first straight bevel gear 26 has only one tooth. So the first straight bevel gear 26 meshes with the first spur gear 25 once when it rotates one week, causing the first spur gear 25 to rotate. The first steering column 28 rotates simultaneously, causing the turntable 1 to rotate. When the turntable 1 rotates once, one limiting tube 19 rotates to the position of the installation hole 3. The copper bar in the limiting tube 19 slides down along the limiting tube 19 and passes through the installation hole 3 into the copper bar groove of the rotor 9. While the turntable 1 rotates, the second straight bevel gear 5 rotates. The second straight bevel gear 5 has only one tooth. So the second straight bevel gear 5 meshes with the second spur gear 4 once when it rotates one week. After the copper bar enters one copper bar groove of the rotor 9, the rotor 9 rotates to turn another copper bar groove to the position corresponding to the installation hole 3 until all the copper bar grooves of the rotor 9 are assembled with copper bars.
[0024] Refer to Figure 3 and Figure 4 , There is a rotor 9 at the lower end of the fixing block 8. Clamping blocks 32 are fixedly installed on both sides of the fixing block 8. There is a connecting groove 29 in the middle of the rotor 9. There are clamping grooves 31 on both sides in the connecting groove 29. There is an end ring 10 at the lower end of the rotor 9. The clamping of the clamping blocks 32 and the clamping grooves 31 enables the rotor 9 to be fixed on the fixing block 8.
[0025] Refer to Figure 1 , There is a heating block 11 below the end ring 10. The heating block 11 abuts against the copper bar and the end ring 10 to weld the copper bar and the end ring 10 together.
[0026] Refer to Figure 1 and Figure 2, a placement plate 12 is provided at the lower end of the heating block 11. Two plate sliding grooves 13 are provided at the lower end of the placement plate 12. Two plate sliders 30 are slidably connected in each of the two plate sliding grooves 13. Two connecting blocks 15 are provided below the placement plate 12. Two block sliding grooves 21 are provided at the upper ends of the two connecting blocks 15. Two block sliders 23 are slidably connected in each of the two block sliding grooves 21. The two plate sliding grooves 13 and the two block sliding grooves 21 are in one-to-one correspondence in position. One side of each of the four plate sliders 30 is fixedly installed with a connecting rod 14. The other ends of the four connecting rods 14 are respectively cross-fixedly connected to one side of the four block sliders 23. The four connecting rods 14 are cross-connected in pairs, and the cross-connected parts of the two connecting rods 14 are rotatably connected. Fixed rods 18 are fixedly connected between the four block sliders 23 sliding in different block sliding grooves 21. Nuts 24 are fixedly installed in the middle of the two fixed rods 18. A bidirectional threaded rod 22 is rotatably connected between the two nuts 24. The lower ends of the two connecting blocks 15 are fixedly installed with a bottom plate 17.
[0027] When welding the end of the copper bar rotor 9, rotate the bidirectional threaded rod 22, and the two nuts 24 move towards the inside of the threaded rod, causing the plate sliders 30 to slide towards the middle of the plate sliding grooves 13. At the same time, the block sliders 23 move towards the middle of the block sliding grooves 21, and the cross connecting rods 14 on both sides move towards the middle of the block sliding grooves 21, and the cross angle becomes smaller, raising the height of the placement plate 12 so that the heating block 11 can abut against the end ring 10 and the copper bar to weld the end. After welding the end of the copper bar rotor 9 is completed, rotate the bidirectional threaded rod 22 in the reverse direction, causing the two nuts 24 to move towards the outside of the threaded rod, causing the plate sliders 30 to slide towards both sides of the plate sliding grooves 13. At the same time, the block sliders 23 move towards both sides of the block sliders 23, and the cross connecting rods 14 on both sides move towards both sides of the block sliding grooves 21, and the cross angle becomes larger, lowering the height of the placement plate 12 so that the heating block 11 no longer abuts against the end ring 10 and the copper bar to complete the welding of the end.
[0028] Refer to Figure 2 , a forward and reverse motor 16 is fixedly installed at one end of the bidirectional threaded rod 22, and the output end of the forward and reverse motor 16 is connected to one end of the bidirectional threaded rod 22. When the motor is started, the forward and reverse motor 16 can cause the bidirectional threaded rod 22 to rotate.
[0029] Refer to Figure 1 , a first motor 27 is provided at the lower end of the first straight bevel gear 26, and the output end of the first motor 27 is connected to the first straight bevel gear 26. When the motor is started, the first motor 27 causes the first straight bevel gear 26 to rotate.
[0030] Refer to Figure 1 , a second motor 6 is fixedly installed at the lower end of the second straight bevel gear 5, and the output end of the second motor 6 is connected to the second straight bevel gear 5. When the motor is started, the second motor 6 causes the second straight bevel gear 5 to rotate.
[0031] Working principle: When welding the end of the copper bar rotor 9, the copper bar is placed into the limiting tube 19. The first straight bevel gear 26 rotates. The first straight bevel gear 26 has only one tooth, so the first straight bevel gear 26 meshes with the first spur gear 25 once in one rotation, causing the first spur gear 25 to rotate. The first steering column 28 rotates simultaneously, causing the turntable 1 to rotate. Each time the turntable 1 rotates, one limiting tube 19 rotates to the position of the mounting hole 3. The copper bar in the limiting tube 19 slides downward along the limiting tube 19, passes through the mounting hole 3, and enters the copper bar groove of the rotor 9. While the turntable 1 rotates, the second straight bevel gear 5 rotates. The second straight bevel gear 5 has only one tooth, so the second straight bevel gear 5 meshes with the second spur gear 4 once in one rotation. After the copper bar enters one copper bar groove of the rotor 9, the rotor 9 rotates to turn another copper bar groove to the position corresponding to the mounting hole 3 until all the copper bar grooves of the rotor 9 are assembled with copper bars.
[0032] When welding the end of the copper bar rotor 9, rotate the bidirectional threaded rod 22. The two nuts 24 move towards the inside of the threaded rod, causing the plate slider 30 to slide towards the middle of the plate chute 13. At the same time, the block slider 23 moves towards the middle of the block chute 21. The cross connecting rods 14 on both sides move towards the middle of the block chute 21, and the crossing angle becomes smaller. The height of the placement plate 12 is adjusted upward, enabling the heating block 11 to abut against the end ring 10 and the copper bar to weld the end. After welding the end of the copper bar rotor 9, rotate the bidirectional threaded rod 22 in the reverse direction, causing the two nuts 24 to move towards the outside of the threaded rod, causing the plate slider 30 to slide towards both sides of the plate chute 13. At the same time, the block slider 23 moves towards both sides of the block slider 23. The cross connecting rods 14 on both sides move towards both sides of the block chute 21, and the crossing angle becomes larger. The height of the placement plate 12 is adjusted downward, enabling the heating block 11 to no longer abut against the end ring 10 and the copper bar, thus completing the welding of the end.
[0033] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
