Description

Technical Field

[0001] This utility model relates to the field of motor stator welding technology, and in particular to a servo motor stator round welding mechanism. Background Technology

[0002] Servo motor stators are typically assembled from multiple stator blocks. After assembly, the joints between the blocks need to be welded to ensure the overall structural strength and electromagnetic stability of the stator.

[0003] Currently, most stator welding methods are semi-automated operations, with each process being relatively dispersed and independent, requiring a large amount of manual intervention for transfer, clamping, and adjustment. Existing technology lacks integrated welding equipment capable of achieving a complete automated process of "stator loading and positioning, station switching, automatic rotation, and laser welding."

[0004] Therefore, there is an urgent need in this field to provide a servo motor stator assembly and welding mechanism that can realize the integrated automated continuous operation of stator feeding and positioning, station switching, automatic rotation indexing and laser welding. Utility Model Content

Then, the material stator is placed on the stator support 302 of the electric cylinder 2 301. After that, the electric cylinder 1 201 of the elastic pressure rod assembly 2 presses down, so that the pressure rod 202 presses on the top of the stator.

[0046] Step 2: The elastic pressure rod assembly 2 and the stator support assembly 3 move together to the position of the fixture 5. The stator is limited by the limiting protrusion 501 of the fixture 5. After that, the elastic pressure rod assembly 2 and the stator support assembly 3 are reset.

[0047] Step 3: The cylinder 403 in the support plate lifting and rotating assembly 4 extends, driving the support plate 401 to rise, so that the limiting block at the end of the support plate 401 is no longer engaged with the limiting protrusion 902 in the support plate limiting assembly 9, so that the fixture 5 on the support plate 401 can be rotated to the laser welding position under the action of the motor 402.

[0048] Step three: The limiting post 6031 on the rotating platform 603 of the jig lifting and rotating assembly 6 is inserted into the limiting groove 502 of the jig 5. The rotating platform 603 is then raised by cylinder 601, and the laser emitter 801 welds one of the vertical seams of the stator via the longitudinal movement module 803. Afterwards, motor 604 rotates the rotating platform 603 by a certain angle, so that the other weld seam of the stator faces the laser emitter 801, allowing the laser emitter 801 to weld this seam. Motor 604 repeats this rotation multiple times until all weld seams of the stator are completed. After welding, the stator is removed, and the jig lifting and rotating assembly 6 is reset.
