[0072] Working principle: In actual use, first, the mechanical gripper or other device makes a plurality of stator cores arranged on the jig. The conveying belt 1 moves to the front of the base 3. Then the feeding device grabs the jig 21 and arranges it above the intermittent rotating seat 4. The jig 21 is sleeved outside the plurality of inner support plates 53.

[0073] After the push rod of the jacking cylinder 51 moves upwards and pushes the jacking shaft 52 to move upwards, the plurality of inner support plates 53 will be pushed to expand outward under the action of the driving eccentric rod 533. Since the synchronous shaft 543 includes two groups of ball screws and the helical grooves on the two groups of ball screws rotate in opposite directions, the inner support plate 53 can rotate the two groups of ball screws during the inward movement, the screw seat two 542 moves in the opposite direction of the screw seat one 534, thereby making the outer pressing plate 54 and the inner support plate 53 move synchronously and in opposite directions. The outer pressing plate 54 and the inner support plate 53 will simultaneously approach the stator core 2 and contact the surface thereof, thereby making the stator core 2 be located directly above the intermittent rotating seat 4. At this time, the stator core 2 will be positioned;

[0074] After the hydraulic cylinder 9 makes the lifting seat 7 move downwards, the lifting seat 7 makes the abutting mechanism 8 and the pressure maintaining plate 71 move downwards, and the pressure maintaining plate 71 will press and maintain the upper part of the stator core 2. At this time, the pressure plate 83 can be inserted into the driving groove 541, thereby making the pressure plate 83 and the outer pressing plate 54 integrated, and the driving face 532 at the top of the driving piece 531 contacts the driving inclined face 851 below the driving plate 85.

[0075] After the inner support plate 53 moves outward under the action of the jacking shaft 52, the driving face 532 pushes the driving inclined face 851 to shift upwards, thereby making the lifting plate 81 and the plurality of abutting plates 86 move upwards. When the abutting plate 86 moves upwards, it will push the pressure plate 83 to move inward. The upper and lower ends of the outer pressing plate 54 are synchronously stressed, so that the upper and lower ends of the outer pressing plate 54 are more evenly stressed, thereby making the outer pressing plate 54 and the inner support plate 53 simultaneously extrude the inner and outer rings of the stator core 2.

[0076] After the laser welding head 63 welds the stator core 2 under the action of the lifting module 61, the intermittent rotating seat 4 rotates by 60 degrees, and then the welding is continued. After three times of continuous rotation and welding, the lifting seat 7 moves upwards, the inner support plate 53 and the outer pressing plate 54 synchronously move away from the stator core 2. The welding stator core 2 is grabbed and removed by the feeding equipment, and then a new stator core 2 is replaced. The above operation is repeated for welding work.

[0077] By arranging the intermittent rotating intermittent rotating seat 4 above the base 3, the pressure maintaining mechanism 5 is arranged on the intermittent rotating seat 4, and the stator core 2 is stacked between the inner support plate 53 and the outer pressing plate 54 in the pressure maintaining mechanism 5. It can support and position the stator core 2, ensure that a plurality of stator cores 2 can completely coincide, improve the welding precision, and the inner support plate 53 and the outer pressing plate 54 can also move away from each other, so that the built-in space is larger, which is convenient for placing and taking out the stator core 2.

[0078] By arranging the lifting seat 7 above and below the base 3, arranging the pressure maintaining plate 71 below the lifting seat 7, and arranging the abutting mechanism 8, when the inner supporting plate 53 and the outer pressure plate 54 are synchronously close to the inner and outer rings of the stator core 2, the abutting mechanism 8 can press above the outer pressure plate 54, so that the entire outer pressure plate 54 is more uniformly stressed, and the inner supporting plate 53, the outer pressure plate 54 and the pressure maintaining plate can press and maintain the pressure of the stator core 2 in multiple directions, so that the multiple stator cores 2 are more closely connected, and the size change after welding is small, and the precision is improved.

[0083] S4, the lifting seat 7 is lowered by the pushing rod of the hydraulic cylinder 9, the pressure maintaining plate 71 presses and maintains the pressure of the stator core 2;

[0084] S5, the inner supporting plate 53 and the outer pressure plate 54 press and maintain the pressure of the stator core 2 inside and outside;

[0085] S6, two groups of welding mechanisms 6 weld the side surfaces of the stator core 2, each welds two groups of welds, the intermittent rotating disc rotates 60 degrees and welds again, after welding three times, the lifting seat 7 moves up, the inner supporting plate 53 and the outer pressure plate 54 synchronously move away from the stator core 2, the feeding equipment grabs the welded stator core 2 and takes it down, then a new stator core 2 is replaced, and the above operation is repeated for welding work.
