Description

Technical Field

[0001] The present invention relates to the technical field of motor production equipment, and particularly to a welding device for a motor iron core. Background Art

[0002] A motor mainly consists of a stator, a rotor, and other accessories. The motor stator iron core is one of the most important parts of the motor. Its structure can directly affect the performance and stability of the motor. Welding can arrange the iron core sheets according to certain rules and fuse and connect them through heating and pressure to form a solid whole. This connection method significantly enhances the structural stability of the iron core, enabling it to withstand various forces and vibrations during the operation of the motor, thereby ensuring the long-term stable operation of the motor.

[0003] When welding the iron core sheets of the motor, it is preferred to arrange them first. At this time, the outer sides of the iron core sheets are stacked together, and it is difficult to uniformly remove oil from the outer sides of the iron core sheets during the production process, resulting in oil adhesion on the outer sides of the iron core sheets. The oil will decompose or volatilize under laser heating, generating a large amount of gases, such as organic substances like hydrogen and carbon, or inorganic substances like water vapor. These gases will form pores in the weld, affecting the density and strength of the weld. This problem needs to be improved. Summary of the Invention

[0009] According to the above technical solution, the feeding component includes a fixed partition, an airbag, a pressing frame, a flow-through pipe, a liquid storage tank, a spring, a piston plate, an air suction pipe, and a feeding hose. The fixed partition is fixedly connected to the middle of the inner top of the machine body. The airbag is fixedly connected to the outer side of the fixed partition. The pressing frame is fixedly connected to the back of the ball screw pair. The flow-through pipe is fixedly connected to the back of the airbag.

The piston plate is fixedly connected to the rear end of the spring. The air suction pipe is fixedly connected to the front of the airbag. The feeding hose is fixedly connected to the rear side of the top of the liquid storage tank.

[0010] According to the above technical solution, the output shaft of the driving motor I penetrates through the fixed support frame and extends to the inner side of the fixed support frame and is fixedly connected to the bidirectional threaded rod. The outer side of the pressing roller is slidably connected to the bottom of the rotating arm plate.

[0011] According to the above technical solution, a receiving block is fixedly connected to the inner bottom of the storage groove. The lifting section of the electric lifting rod penetrates through the top of the lifting positioning frame and extends to the lower side of the lifting positioning frame and is fixedly connected to the top of the lifting plate.

[0012] According to the above technical solution, an air outlet pipe is opened at the bottom of the liquid storage tank, and a one-way valve I is arranged in the air outlet pipe. The input end of the one-way valve I is at the top. A one-way valve II is arranged in the air suction pipe. The input end of the one-way valve II is at the top.

[0013] According to the above technical solution, an emulsifier is filled in the liquid storage tank at the rear side of the piston plate.

[0014] According to the above technical solution, the rear end of the flow-through pipe is fixedly connected to the front of the liquid storage tank, and the airbag is communicated with the front side inside the liquid storage tank through the flow-through pipe.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: Before welding the iron core, place the iron core on the top of the rotating base, and then control the first driving motor to work. When the first driving motor works, the bidirectional threaded rod rotates accordingly. At this time, the ball nut pair moves on the bidirectional threaded rod, and the ball nut pair gradually moves towards the middle of the bidirectional threaded rod. At the same time, the pressing roller at the inner top of the ball nut pair contacts the bottom of the rotating arm plate, causing the pressing roller to lift the bottom of the rotating arm plate, enabling the rotating arm plate to rotate within the fixed rotating rod. When the ball nut pair moves close to the middle of the bidirectional threaded rod, the distance when the pressing roller lifts the rotating arm plate is the largest, making the rotating arm plate perpendicular to the top surface of the machine body. At this time, the surface of the cleaning sponge pad contacts the surface of the iron core. Then, control the electric lifting rod to drive the lifting plate to press down, enabling the positioning turntable to position the top of the iron core. As the second driving motor works, the positioning turntable drives the iron core to rotate on the top of the rotating base. At this time, the outer wall of the iron core rotates and contacts the cleaning sponge pad, and the outer side of the iron core can be cleaned;

[0016] During the process of the ball nut pair moving close to the middle of the bidirectional threaded rod, the pressing frame moves and squeezes the airbag, causing the air in the airbag to be sent into the liquid storage tank through the flow pipe, increasing the pressure on the front side in the liquid storage tank. At this time, the spring stretches, causing the piston plate to move. When the piston plate moves, the emulsion liquid in the liquid storage tank is squeezed into the cleaning sponge pad through the feeding hose, absorbed by the cleaning sponge pad, and under the action of gravity, the emulsifier infiltrates from the upper side to the lower side of the cleaning sponge pad, achieving a better cleaning effect when removing oil from the outer side of the iron core;

[0017] After the cleaning work on the outer side of the iron core is completed, control the first driving motor to work, causing the ball nut pair to move outside the bidirectional threaded rod. At this time, the pressing frame separates from the airbag, causing the one-way valve in the air outlet pipe at the bottom of the liquid storage tank to work, discharging the air in the liquid storage tank. At this time, the airbag elastically recovers, and at the same time, the one-way valve in the air suction pipe works, sucking in the air outside the iron core at the top of the machine body, which can accelerate the air flow outside the iron core. At the same time, when the second driving motor drives the positioning turntable to rotate, the iron core under the positioning turntable rotates on the top of the rotating base, which can accelerate the drying rate of the iron core;

[0018] When welding is required, slide the laser welder on the sliding seat to the designated position, and then start the laser welder to work, causing the laser welder to weld the outer side of the iron core. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A receiving block is fixedly connected to the bottom of the storage groove 701 , and the lifting section of the electric lifting rod 706 passes through the top of the lifting positioning frame 705 and extends to the bottom of the lifting positioning frame 705 and is fixedly connected to the top of the lifting plate 707 .

[0036] The bottom of the liquid storage tank 805 is provided with an air outlet pipe, and a check valve one is arranged in the air outlet pipe. The input end of the check valve one is at the top. A check valve two is arranged in the air suction pipe 808, and the input end of the check valve two is at the top.

[0037] The inside of the liquid storage tank 805 is filled with an emulsifier at the rear side of the piston plate 807.

[0039] Before welding the iron core, place the iron core on the top of the rotating base 5, and then control the driving motor one 602 to work. When the driving motor one 602 works, the bidirectional threaded rod 603 rotates accordingly. At this time, the ball nut pair 604 moves on the bidirectional threaded rod 603, so that the ball nut pair 604 gradually moves towards the middle of the bidirectional threaded rod 603. At the same time, the pressing roller 605 at the top inside the ball nut pair 604 contacts the bottom of the rotating arm plate 703, so that the pressing roller 605 jacks up the bottom of the rotating arm plate 703, causing the rotating arm plate 703 to rotate within the fixed rotating rod 702. When the ball nut pair 604 moves close to the middle of the bidirectional threaded rod 603, the distance when the pressing roller 605 jacks up the rotating arm plate 703 is the largest, making the rotating arm plate 703 perpendicular to the top surface of the machine body 2. At this time, the surface of the cleaning sponge pad 704 contacts the surface of the iron core. Then control the electric lifting rod 706 to drive the lifting plate 707 to press down, so that the positioning turntable 709 positions the top of the iron core. As the driving motor two 708 works, the positioning turntable 709 drives the iron core to rotate on the top of the rotating base 5. At this time, the outer wall of the iron core rotates and contacts the cleaning sponge pad 704, and the outside of the iron core can be cleaned.

[0040] During the process of the ball nut pair 604 moving close to the middle of the bidirectional threaded rod 603, the pressing frame 803 moves and squeezes the airbag 802, so that the air in the airbag 802 is sent into the liquid storage tank 805 through the flow-through pipe 804, increasing the pressure on the front side inside the liquid storage tank 805. At this time, the spring 806 stretches, causing the piston plate 807 to move. When the piston plate 807 moves, the emulsion liquid in the liquid storage tank 805 is squeezed into the cleaning sponge pad 704 through the feeding hose 809, absorbed by the cleaning sponge pad 704, and under the action of gravity, the emulsifier infiltrates from the upper side to the lower side of the cleaning sponge pad 704, making the cleaning effect better when removing oil from the outside of the iron core.

[0041] After the cleaning work on the outer side of the iron core is completed, control the driving motor 602 to work, so that the ball nut pair 604 moves on the outer side of the bidirectional threaded rod 603. At this time, the extrusion frame 803 is separated from the airbag 802, and the check valve I in the air outlet pipe at the bottom of the liquid storage tank 805 works to discharge the air in the liquid storage tank 805. At this time, the airbag 802 elastically recovers. At the same time, the check valve II in the air suction pipe 808 works to suck the air at the outer side of the iron core at the top of the machine body 2, which can accelerate the air flow on the outer side of the iron core. At the same time, when the driving motor 708 drives the positioning turntable 709 to rotate, the iron core under the positioning turntable 709 rotates on the top of the rotating base 5, which can accelerate the drying rate of the iron core.

[0042] When welding is required, make the laser welder 4 slide on the sliding seat 3 to the specified position, and then start the laser welder 4 to work, so that the laser welder 4 welds the outer side of the iron core.
