Description

Technical Field

[0001] This application relates to the field of welding technology, and in particular to an induction welding device for the end of a copper bar rotor. Background Art

[0002] The copper bar rotor end welding device is a special equipment dedicated to welding copper bars (also known as copper busbars or copper end rings) to the rotor core or other components during the manufacturing process of electric motor rotors. This device usually adopts advanced welding technologies, such as induction welding, resistance welding, or laser welding, etc., to achieve efficient, stable, and high-quality welding effects.

[0003] In the prior art, copper sheets need to be manually inserted into the large rotor core one by one, and then their ends are welded at high temperature. Since the insertion is manual, the efficiency is relatively low. Therefore, this application provides an induction welding device for the end of a copper bar rotor. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of this application is an induction welding device for the end of a copper bar rotor to solve the technical problem of too low efficiency of manual copper sheet filling.

[0005] The above object of this application is achieved through the following technical solutions: It includes a base and an intermittent transportation device on the base. The intermittent transportation device has a rotating structure. The rotating structure includes a rotating shaft rotatably connected to the base. A rotating gear is fixedly arranged on the rotating shaft. The rotating gear is meshed with an intermittent gear. A rotating motor is arranged at the bottom of the intermittent gear. The output end of the rotating motor is fixedly connected to the intermittent gear. The bottom of the rotating motor is fixedly connected to the base. A linkage shaft is fixedly arranged at the upper end of the rotating shaft. An end ring is sleeved on the linkage shaft. Insertion ports are evenly arranged on the end ring. A guiding shell is fixedly arranged outside the end ring. A guiding ring is fixedly arranged at one end of the guiding shell away from the end ring. Guiding grooves are evenly arranged on the guiding ring. The guiding ring is installed on the linkage shaft.

[0006] By adopting the above technical solutions, when it is necessary to insert copper sheets into the insertion slots on the end ring, start the rotating motor. The rotating motor drives the intermittent gear, which in turn drives the rotating gear, so that the linkage shaft on its rotating shaft rotates and stops alternately, thereby improving the insertion efficiency.

[0007] Furthermore, the intermittent transportation device includes a conveyor belt, a driving shaft on one side of the conveyor belt, and a driven shaft on the other side. A driven gear is fixedly arranged on the driving shaft. The driven gear is rotationally connected to a support rod, and the bottom of the support rod is fixedly connected to a base. One side of the driven gear is meshed with a driving gear. The driving gear passes through the support rod and is provided with a driving motor. The output end of the driving motor is fixedly connected to the driving gear. A guiding frame is arranged on the conveyor belt. Multiple copper sheets are arranged inside the guiding frame. Connecting columns are fixedly arranged at both ends of the guiding frame, and the bottoms of the connecting columns are fixedly connected to the base. A conveying strip is also fixedly arranged on the conveyor belt.

[0008] By adopting the above technical solution, when it is necessary to transport the copper sheets, the driving motor is started. The driving motor drives the driving gear to rotate, and at the same time intermittently drives the driven gear. Thereby making the conveyor belt move and stop alternately. The copper sheets will fall into the guiding grooves in the lower guiding ring one by one along with the movement of the conveying strip, and thus enter the inserting grooves in the end ring. By inserting the guiding ring on the linkage shaft, it can be ensured that while it rotates with the rotation of the rotating motor, it can also be normally disengaged.

[0009] Furthermore, the notch of the guiding groove inclines inwards.

[0010] By adopting the above technical solution, the inclined guiding groove can ensure that the copper sheets are more easily inserted into the guiding groove.

[0011] Furthermore, inclined surfaces are opened downward on both sides of the bottom of the copper sheet.

[0012] By adopting the above technical solution, by opening inclined surfaces at the bottom of the copper sheet, it can be ensured that it is more easily inserted into the guiding groove.

[0013] Furthermore, the insertion opening matches the inclined surface opened at the bottom of the copper sheet.

[0014] By adopting the above technical solution, by setting the insertion opening and the bottom of the copper sheet to be the same, it can ensure the stability after the insertion is completed. At the same time, in subsequent thermal welding, it can improve the thermal welding efficiency.

[0015] Furthermore, a heating solder pad is arranged on the linkage shaft in a threaded manner.

[0016] By adopting the above technical solution, through the heating solder pad arranged in a threaded manner, after the copper sheet is inserted into the insertion opening of the end ring, the heating solder pad is rotated and lifted to contact the bottom of the end ring, thereby heating and welding the copper sheet and the end ring together.

[0017] Furthermore, linkage blocks are fixedly connected around the heating solder pad.

[0018] By adopting the above technical solution, the arrangement of the linkage blocks makes it easier to apply force when rotating the heating solder pad.

[0019] Furthermore, a linkage rod is rotatably arranged on the linkage shaft.

[0020] By adopting the above technical solution, the arrangement of the linkage rod can avoid direct contact with the heating pad for adjustment.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. Through the cooperation of the driving motor and the rotating motor, the conveyor belt and the linkage shaft are alternately moved and stopped, ensuring that the copper sheet can accurately fall into the guiding groove of the guiding ring and then enter the inserting groove of the end ring, thus greatly improving the inserting efficiency of the copper sheet.

[0023] 2. The flange at the bottom of the guiding ring matches the groove on the linkage shaft, ensuring that the guiding ring can stably rotate with the linkage shaft during rotation and can be separated smoothly. In addition, the insertion port matches the inclined surface at the bottom of the copper sheet, ensuring the stability after insertion and improving the welding quality.

[0024] 3. The notch of the guiding groove is inclined inward, making it easier for the copper sheet to enter the guiding groove, further improving the inserting efficiency. At the same time, the inclined surface design at the bottom of the copper sheet also cooperates with it, enabling the copper sheet to enter the inserting groove more smoothly.

[0025] 4. The heating pad with a threaded setting on the linkage shaft can be rotated to contact the bottom of the end ring after the copper sheet is inserted into the insertion port of the end ring, so as to perform heating welding. This design not only simplifies the welding process but also improves the welding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0031] The following further describes the present application in detail with reference to the accompanying drawings.

[0032] Example, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a copper strip rotor end induction welding device, including a base 1 and an intermittent transportation device on the base 1, and an intermittent transportation device rotating structure. The rotating structure includes a rotating shaft 4 rotatably connected to the base 1. The axis of the rotating shaft 4 is perpendicular to the base 1. A rotating gear 41 is sleeved outside the rotating shaft 4. The rotating gear 41 is fixedly arranged on the rotating shaft 4. The rotating gear 41 is meshed with an intermittent gear 42. The intermittent gear 42 is provided with a rotating motor 43 at the bottom. The output end of the rotating motor 43 is fixedly connected to the intermittent gear 42. The rotating motor 43 is fixedly connected to the base 1 at the bottom. A linkage shaft 44 is fixedly arranged at the upper end of the rotating shaft 4. An end ring 45 is sleeved on the linkage shaft 44. Insertion interfaces 46 are evenly opened on the end ring 45. A guide housing 47 is fixedly arranged outside the end ring 45. A guide ring 48 is fixedly arranged at one end of the guide housing 47 away from the end ring 45. Guide grooves 49 are evenly opened on the guide ring 48. The guide ring 48 is installed on the linkage shaft 44. When it is necessary to insert the copper sheet 31 into the insertion slot of the end ring 45, the rotating motor 43 is started. The rotating motor 43 drives the intermittent gear 42, thereby driving the rotating gear 41 to rotate the linkage shaft 44 on its rotating shaft 4 one by one and stop one by one, thereby improving the insertion efficiency.

[0033] In this embodiment, the intermittent transportation device includes a conveyor belt 2, a driving shaft 21 on one side of the conveyor belt 2, and a driven shaft 22 on the other side. A driven gear 23 is fixedly arranged on the driving shaft 21. The driven gear 23 is rotationally connected to a support rod 24. The bottom of the support rod 24 is fixedly connected to a base 1. One side of the driven gear 23 is meshed with a driving gear. The driving gear passes through the support rod 24 and is provided with a driving motor 26. The output end of the driving motor 26 is fixedly connected to the driving gear. A guiding frame 3 is arranged on the conveyor belt 2. A plurality of copper sheets 31 are arranged inside the guiding frame 3. Connection columns 32 are fixedly arranged at both ends of the guiding frame 3. The bottom of the connection columns 32 is fixedly connected to the base 1. A conveying strip 7 is also fixedly arranged on the conveyor belt 2. A flange 5 is fixedly arranged at the bottom of the guiding ring 48. A groove 51 matching the flange 5 is formed on the linkage shaft 44. When it is necessary to transport the copper sheets 31, the driving motor 26 is started. The driving motor 26 drives the driving gear to rotate, and at the same time intermittently drives the driven gear 23. Thus, the conveyor belt 2 moves and stops alternately. The copper sheets 31 will fall into the guiding grooves 49 in the lower guiding ring 48 one by one along with the movement of the conveying strip 7, and then enter the insertion slots in the end ring 45. By inserting the guiding ring 48 on the linkage shaft 44, it can be ensured that it rotates along with the rotation of the rotation motor 43 and can be normally detached at the same time.

[0034] In this embodiment, the notch of the guiding groove 49 inclines inwards. The inclined guiding groove 49 can ensure that the copper sheets 31 are more easily inserted into the guiding groove 49. The two sides of the bottom of the copper sheet 31 are provided with inclined surfaces facing downwards. By providing inclined surfaces at the bottom of the copper sheet 31, it can be ensured that the copper sheet 31 more easily enters the guiding groove 49. The insertion port 46 matches the inclined surfaces provided at the bottom of the copper sheet 31. By setting the insertion port 46 and the bottom of the copper sheet 31 to be the same, the stability after insertion can be ensured, and at the same time, the efficiency of thermal welding can be improved during subsequent thermal welding.

[0035] In this embodiment, a heating solder pad 6 is arranged on the linkage shaft 44 in a threaded manner. By arranging the heating solder pad 6 in a threaded manner, after the copper sheet 31 is inserted into the insertion port of the end ring 45, the heating solder pad 6 is rotated and lifted to contact the bottom of the end ring 45, thereby heating and welding the copper sheet 31 and the end ring 45 together.

[0036] In this embodiment, a linkage block 61 is fixedly connected around the heating solder pad 6. The arrangement of the linkage block 61 makes it easier to apply force when rotating the heating solder pad 6. A linkage rod 62 is rotatably arranged on the linkage shaft 44. The arrangement of the linkage rod 62 can avoid direct contact with the heating solder pad 6

[0037] Specific implementation process: Multiple copper sheets 31 are placed inside the guiding frame 3. The two sides of the bottom of the copper sheet 31 are provided with inclined planes facing downward to facilitate entry into the guiding groove 49. Start the driving motor 26, and the motor drives the driving gear to rotate, and then drives the conveyor belt 2 to move through the driven gear 23. The conveyor belt 2 drives the guiding frame 3 and the copper sheet 31 to move together.

[0038] Intermittent movement: Through the control of the driving motor 26, the conveyor belt 2 is made to move and stop intermittently so that the copper sheet 31 can accurately fall into the lower guiding ring 48. Start the rotating motor 43: Start the rotating motor 43, and the motor drives the intermittent gear 42 to rotate, and then drives the rotating shaft 4 and the linkage shaft 44 to rotate through the rotating gear 41. As the rotating shaft 4 rotates, the end ring 45 on the linkage shaft 44 also rotates. When the copper sheet 31 moves to above the end ring 45 along with the guiding frame 3, due to the intermittent movement of the conveyor belt 2, the copper sheet 31 will fall into the guiding groove 49 of the guiding ring 48 and then enter the insertion opening 46 of the end ring 45. After the copper sheet 31 is inserted into the insertion opening 46 of the end ring 45, heat the heating pad 6 on the linkage shaft 44 to make it contact the bottom of the end ring 45 and start heating. At an appropriate temperature and time, the heating pad 6 heats the copper sheet 31 and the end ring 45 to melt and weld them together.

[0039] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of the 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.
