Description

Technical Field

[0001] The utility model relates to the technical field of motor stator core processing, in particular to a welding tool for preparing a water-cooled motor stator. Background Art

[0002] With the rapid development of my country's economy, the requirements for motor components are becoming higher and higher. Among them, the quality of the stator core plays an important role in the operation of the motor. The stator core is an integral structure welded by multiple punching sheets. Therefore, the quality of the stator core depends to a large extent on the welding tooling of the stator core.

[0003] At present, a large amount of heat is generated during the welding process, and there is no effective cooling method, which causes the thermal deformation of the core punching to increase, and the precision of the stator core to decrease, which reduces the quality of the stator core. In addition, the poor stability during the welding process will cause the welding to be loose, which affects the service life of the motor. Therefore, a method is now provided. Utility Model Content

[0004] In response to the deficiencies of the prior art, the present invention provides a welding tool for preparing a water-cooled motor stator. By arranging a water-cooling component in the protective block and using a cooling structure, the stator core is effectively cooled during welding, thereby effectively avoiding deformation of the stator due to high temperature and ensuring the accuracy of the stator core. By cooperating with the stator bearing component and the fixing component, the stator is fixed, ensuring stability and welding quality during welding of the stator, avoiding affecting the service life of the motor, and overcoming the deficiencies of the prior art.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] Preferably, the fixing assembly includes two U-shaped sleeves respectively fixed on the side walls of the two protective blocks, and an L-shaped connecting rod is slidably sleeved on the two U-shaped sleeves. A fixing ring is welded between the ends of the horizontal sections of the two L-shaped connecting rods, and a connecting block is welded on one side of the vertical sections of the two L-shaped connecting rods. The bottom ends of the two connecting blocks are connected to electric push rods, and the bottom ends of the two electric push rods are fixed on the base.

[0011] Preferably, the inner diameter of the fixing ring is larger than the diameter of the ventilation pipe.

[0012] Preferably, the stator bearing assembly includes a support ring, and three inwardly extending protrusions are equidistantly arranged on the inner side of the support ring. The bottom ends of the three protrusions are connected to support springs, and the bottom ends of the three support springs are fixed to the upper end surface of the base.

[0013] Preferably, the purification component includes an air purifier connected to the side of the base, and the air suction end of the air purifier is connected to an air suction hood.

[0014] Preferably, the air suction hood is located above one side of the support ring, and the support ring is sleeved on the outside of the ventilation pipe.

[0015] The beneficial effects of the utility model are:

The cooling water flows through the serpentine flow channel in the protective block to take away the heat generated on the outside of the welded stator, and the fan is turned on to blow air out from the air outlet of the ventilation pipe to cool the inside of the stator, thereby effectively avoiding deformation of the stator due to high temperature and ensuring the accuracy of the stator core.

[0017] 2. Use the two electric push rods to shrink and drive the two L-shaped connecting rods to descend, and then use the L-shaped connecting rods to drive the fixing ring to descend. Use the fixing ring to press the stator to fix the stator, ensuring the stability and welding quality during stator welding and avoiding affecting the service life of the motor.

[0018] In summary, by setting up a water-cooling component in the protective block and using a cooling structure, the stator core can be effectively cooled during welding, thereby effectively avoiding deformation of the stator due to high temperature and ensuring the accuracy of the stator core. By using the stator bearing component and the fixing component in combination, the stator can be fixed, ensuring the stability and welding quality of the stator during welding, and avoiding affecting the service life of the motor.

A purification component is installed on one side of the base 1.

[0026] The water cooling assembly includes a serpentine flow channel arranged inside the protective block 9, with a water inlet 8 and a water outlet 10 respectively provided at both ends of the serpentine flow channel;

[0027] The cooling structure includes air outlets 7 evenly arranged on the ventilation pipe 6, and a fan 15 is installed at the top of the ventilation pipe 6;

[0028] The height of the ventilation pipe 6 is greater than the height of the two protective blocks 9, and the fan 15 is located above the two protective blocks 9;

[0029] The fixing assembly includes two U-shaped sleeves 3 respectively fixed to the side walls of the two protective blocks 9, and an L-shaped connecting rod 5 is slidably sleeved on each of the two U-shaped sleeves 3. A fixing ring 13 is welded between the ends of the horizontal sections of the two L-shaped connecting rods 5. A connecting block 4 is welded to one side of the vertical section of the two L-shaped connecting rods 5. The bottom ends of the two connecting blocks 4 are connected to the electric push rods 2. The bottom ends of the two electric push rods 2 are fixed to the base 1. The inner diameter of the fixing ring 13 is larger than the diameter of the ventilation pipe 6;

[0030] The stator bearing assembly includes a support ring 14, and three inward-extending protrusions 16 are equidistantly arranged on the inner side of the support ring 14. The bottom ends of the three protrusions 16 are connected to support springs 17, and the bottom ends of the three support springs 17 are fixed to the upper end surface of the base 1. The purification assembly includes an air purifier 11 connected to the side of the base 1, and the air intake end of the air purifier 11 is connected to the air intake hood 12.
