[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example

[0027] like Figures 1 to 7 As shown, this embodiment provides a stator oil spraying ring welding equipment, including an equipment platform 1, a wire body 6 installed on the top of the equipment platform 1, a tray 7 for placing the stator 13 installed at the wire body 6, and a rotary lifting mechanism 3 for driving the tray 7 to rotate on the top of the equipment platform 1.

[0028] In detail, the rotary lifting mechanism 3 includes a servo cylinder 31, a fixed plate 32, a lifting plate 34, and a rotating plate 35. The fixed plate 32 is fixedly installed on the equipment platform 1. The servo cylinder 31 is fixedly installed at the bottom of the fixed plate 32. The output end of the servo cylinder 31 extends to the top of the fixed plate 32 and is fixedly connected to the bottom of the lifting plate 34. A first hollow rotary platform 33 is installed in the middle of the lifting plate 34. The rotating plate 35 is installed at the output end of the first hollow rotary platform 33. The fixed plate 32 and the lifting plate 34 are connected by two sets of telescopic guide rods. The two sets of telescopic guide rods are located at the two end corners on the left and right sides of the fixed plate 32 and the lifting plate 34, respectively, to provide more stable support.

[0029] Two trusses 2 are mounted on the top of the equipment platform 1. A horizontal plate 10 for reciprocating motion is mounted on each truss 2 via a linear module 8. It should be noted that, to coordinate with the movement of the linear module 8, the linear module 8 is mounted on the left truss 2, while a second slide rail is mounted on the right truss 2. This enables the linear module 8 to drive the horizontal plate 10 in reciprocating motion. A laser welder 12 for welding the stator 13 is mounted on the horizontal plate 10 via a tripod 11. The tripod 11 is fixedly connected to a back plate 125. The back plate 125... A welding slide plate 122 is mounted on the surface via a third slide rail 123. A lead screw 124 is rotatably mounted on the front of the back plate 125. A lead screw bearing seat is threaded onto the lead screw 124. The welding slide plate 122 is welded to the lead screw bearing seat. A lead screw retainer 121 is provided at the top of the lead screw 124 to prevent it from rotating. When it is necessary to adjust the welding height of the laser welder 12, the position of the laser welder 12 can be adjusted by adjusting the lead screw 124. After the laser welder 12 is adjusted according to the actual production needs, the lead screw 124 is locked by the lead screw retainer 121.

[0030] Between the two trusses 2, an oil injection ring positioning mechanism 4 is also installed to adjust the stator 13 in conjunction with the rotating lifting mechanism 3. Specifically, the oil injection ring positioning mechanism 4 includes two mounting strips 41, a mounting plate 43, a crossed roller bearing 45, and a tooling pressure ring 44. The two mounting strips 41 are fixedly installed on the same side of the two trusses 2, the mounting plate 43 is fixedly installed on the two mounting strips 41, the crossed roller bearing 45 passes through the middle of the fixed mounting plate 43, and the tooling pressure ring 44 is sleeved on the end of the stator 13. For the stator 13, as... Figure 5 and Figure 6 As shown, during welding, the lifting mechanism 3 is rotated to lift the stator 13 away from the line body 6, the oil spray ring 14 is fitted onto the end of the stator 13, and then the tooling pressure ring 44 is engaged with the end of the stator 13 to achieve the initial positioning of the oil spray ring 14. The tooling pressure ring 44 has multiple through slots 46 arranged in a ring array to facilitate the welding of the outer edge 16 of the oil spray ring 14 to the side wall of the stator 13.

[0031] Specifically, the inner edge 17 of the oil injection ring 14 is welded to the upper surface wall of the stator 13 end by a laser welder 12, and the outer edge 16 of the oil injection ring 14 is welded to the upper end side wall of the stator 13 by a laser welder 12. The inner ring of the oil injection ring 14 is also provided with multiple evenly distributed oil injection holes 18, which cool the stator 13 by oil cooling. It should be noted that the laser welder 12 welds the inner edge 16 and outer edge 17 of the oil injection ring 14 to the end surface wall of the stator 13 by high temperature. The thickness of the oil injection ring 14 is generally about 2mm, and the two can be welded together by high temperature.

[0032] The top of the equipment platform 1 is also equipped with a rotating clamping mechanism 5, which works in conjunction with the rotating lifting mechanism 3 to clamp and flip the stator 13. Specifically, the rotating clamping mechanism 5 includes a first slide rail 56, a slide plate 55, a rotating bracket 51, a second hollow rotating platform 52, a gripper cylinder 53, a clamping plate 54, a drive motor 57, a gear 58, and a rack 59. Its function is as follows: after welding is completed at one end of the stator 13, the rotating bracket 51 moves closer to the stator 13 through the cooperation of the drive motor 57, the rack 59, and the gear 58. When the stator 13 is placed between the two clamping plates 54, the gripper cylinder 53 drives the two clamping plates 54 to clamp the stator 13, and the second hollow rotating platform 52 drives the entire stator 13 to flip, so as to achieve the purpose of welding the oil spray ring 14 at the other end of the stator 13.

[0033] Specifically, two first slide rails 56 are symmetrically installed on the equipment platform 1, and a slide plate 55 is slidably mounted on the two first slide rails 56. A rotating bracket 51 is fixedly installed on the top of the slide plate 55, and a second hollow rotating platform 52 is fixedly mounted through the rotating bracket 51. A gripper cylinder 53 is fixedly installed on the output end of the second hollow rotating platform 52, and two matching clamping plates 54 are respectively fixedly installed on the two output ends of the gripper cylinder 53. A drive motor 57 is fixedly installed on the slide plate 55, and the output end of the drive motor 57 passes through the slide plate 55 and is coaxially fixedly connected to a gear 58. A rack 59 that meshes with the gear 58 is fixed on one side of each of the two first slide rails 56, so that the drive motor 57 can synchronously drive the meshing rack 59 to move through the drive gear 58.

[0034] In this embodiment of the stator oil spraying ring welding equipment, the stator 13 is first placed on the tray 7 at the line body 6. As the line body 6 moves above the rotary lifting mechanism 3, the rotary lifting mechanism 3 pushes the tray 7 off the line body 6. Then, the oil spraying ring 14 is manually placed on the end of the stator 13, and then the tooling pressure ring 44 is placed on the end of the stator 13 to achieve initial positioning of the oil spraying ring 14. Next, the rotary lifting mechanism 3 continues to move the tray 7 upward, and the copper wire end of the stator 13 extends upward through the crossed roller bearing 45, so that the upper surface of the tooling pressure ring 44 on the stator 13 is in close contact with the lower surface of the crossed roller bearing 45. Under the adjustment of the linear module 8, the laser welder 12 is placed directly above one of the through slots 46 of the tooling pressure ring 44. 12 welds the oil spray ring 14 and the side wall of the stator 13 through the through groove 46. After the welding is completed at this point, the first hollow rotating platform 33 drives the tray 7 to rotate. Because the end of the stator 13 is in contact with the crossed roller bearing 45, the stator 13 will also rotate with the tray 7, so that the next through groove 46 on the tooling pressure ring 44 moves to the bottom of the laser welder 12, thereby achieving welding. This cycle is repeated until all through groove 46 positions are welded. Finally, the linear module 8 adjusts the position of the laser welder 12 so that the welding head of the laser welder 12 moves towards the center of the stator 13, so as to facilitate the welding of the inner side of the oil spray ring 14 to the end of the stator 13. With the cooperation of the rotating lifting mechanism 3, a whole circle of welding work is completed.

[0035] After the stator 13 is welded at one end, the rotary lifting mechanism 3 moves down a certain distance to align with the rotary clamping mechanism 5. The rotary clamping mechanism 5 moves closer to the stator 13 and grabs the stator 13 with two clamping plates 54 controlled by the gripper cylinder 53. The second hollow rotary platform 52 rotates to flip the stator 13. After the flip is completed, the oil spraying ring 14 and the tooling pressure ring 44 are placed on the end of the stator 13 in sequence. The rotary lifting mechanism 3 then moves the stator 13 up to a suitable height and repeats the above process to complete the welding of the oil spraying ring 14.

[0036] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
