Description

Technical Field

[0001] This utility model relates to the field of rotor assembly technology, and in particular to a dual-station laser welding device. Background Technology

[0002] During the assembly process, a copper ring needs to be installed on the rotor shaft. Currently, the copper ring is directly pressed onto the rotor shaft and fixed to the rotor shaft by interference fit. This fixing method is prone to movement after long-term use, which is not conducive to the normal operation of the rotor. Utility Model Content

[0003] The purpose of this invention is to solve the problem mentioned in the background art above, where the copper ring is fixed to the rotor by an interference fit, which is not conducive to the long-term operation of the rotor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dual-station laser welding device includes a conveying device, a welding fixture, and an inclined conveying track. The conveying device includes a conveying frame and a baffle plate disposed at the end to block the rotor. A robotic arm is disposed on one side of the conveying device. The welding fixture includes a support block for placing the rotor. The support block has two placement slots and a limit plate is disposed on one side of the support block. The inclined conveying track is disposed on one side of the welding fixture and is perpendicular to the conveying device. The inclined conveying track has a track groove for the rotor to roll down.

[0006] Preferably, the conveying device further includes a support base, and two conveying frames are provided, which are symmetrically installed on the support base, and a conveyor belt for conveying the rotor is provided between the two conveying frames.

[0007] Preferably, a connecting plate is provided between the baffle and the conveyor belt, the connecting plate is fixed to the conveyor frame, and the end faces of the baffle and the connecting plate are in contact.

[0008] Preferably, an elastic plate is installed on the support block, and the elastic plate and the limiting plate are distributed on both sides of the support block.

[0009] Preferably, the elastic plate includes a connecting portion, an abutting portion, and an inclined portion distributed sequentially from bottom to top, wherein the abutting portion abuts against the iron core end face of the rotor.

[0010] Preferably, the inclined portion has an arc-shaped groove.

[0011] Preferably, the welding fixture further includes a telescopic cylinder, the output end of which is fixed to the support block.

[0012] Preferably, a support plate is provided on the lower side of the limiting plate, and the support plate has mounting holes for mounting the limiting plate.

[0013] Preferably, a laser welding device is provided on one side of the welding fixture.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The baffles and connecting plates on the conveying device allow the rotor to remain stably at the end of the conveying device, making it easy for the robotic arm to grasp it.

[0016] By setting limiting plates and elastic plates on both sides of the support block, the stability of the rotor in the placement slot is improved. The abutting part of the elastic plate abuts against the rotor, and at the same time, the rotor shaft contacts the limiting plate, keeping the copper ring in an accurate position, which facilitates the welding of the copper ring by the laser welding device. The inclined conveyor track facilitates the movement of the rotor after welding. Attached Figure Description

The conveyor belt 14 is a prior art conveyor. The belt surface of the conveyor belt 14 is lower than the top surface of the conveying frame 11. The conveyor belt 14 and the two conveying frames 11 form a conveying trough. A connecting plate 15 is disposed between the baffle 12 and the conveyor belt 14. The connecting plate 15 is fixed to the conveying frame 11. The end faces of the baffle 12 and the connecting plate 15 are in contact. The baffle 12 blocks the rotor conveyed to the end. The connecting plate 15 supports the rotor at the end, so that the rotor at the end is aligned with the other rotors, which is convenient for the robotic arm 5 to grasp.

[0031] The welding fixture 2 includes a support block 21 for placing rotors. A laser welding device 4 is provided on one side of the welding fixture 2. Two placement slots 211 are opened on the support block 21. The welding fixture 2 also includes a telescopic cylinder 22. The output end of the telescopic cylinder 22 is fixed to the support block 21. The telescopic cylinder 22 is existing technology. The telescopic cylinder 22 can adjust the height of the support block 21. A limit plate 23 is provided on one side of the support block 21. The robotic arm 5 picks up two rotors from the conveying device 1 and then places them in the placement slots 211 on the side of the support block 21. The limit plate 23 abuts against the rotor shaft end face on one side of the copper ring, so that the copper ring is always in one position, which is convenient for the laser welding device 4 to weld. A support plate 24 is provided on the lower side of the limit plate 23. The support plate 24 has mounting holes 241 for mounting the limit plate 23. The lower end of the limit plate 23 also has mounting holes 241. The limit plate 23 is fixed to the support plate 24 by bolts and nuts.

[0032] An elastic plate 25 is installed on the support block 21. The elastic plate 25 and the limiting plate 23 are distributed on both sides of the support block 21. The elastic plate 25 cooperates with the limiting plate to limit the rotor, so that the rotor can stay stably on the support block 21. The elastic plate 25 includes a connecting part 251, an abutting part 252 and an inclined part 253 distributed from bottom to top. The connecting part 251 is connected to the support block 21. The abutting part 252 abuts against the iron core end face of the rotor. The inclined part 253 facilitates rotor installation and has a unique guiding function. The elastic plate 25 keeps the copper ring in an accurate position, which facilitates the welding of the copper ring by the laser welding device 4. An arc groove 254 is opened on the inclined part 253, which corresponds to the rotor shaft.

[0033] The inclined conveying track 3 is set on one side of the welding fixture 2. The inclined conveying track 3 is set perpendicular to the conveying device 1. The welding fixture 2 is located between the conveying device 1 and the inclined conveying track 3. The inclined conveying track 3 is provided with a track groove 31 for the rotor to roll down. The track groove 31 is set at an inclination for the rotor to roll down.

[0034] A robotic arm 5 is provided on one side of the conveying device 1. The end of the robotic arm 5 is provided with a clamping plate for gripping the rotor shaft and a rotating part for driving the clamping plate to rotate. The robotic arm 5 is existing technology.

[0035] In use, the conveying device 1 conveys the rotors, which are blocked by the baffle 12 when they reach the end. Then, the robotic arm 5 grabs two rotors and places them on the support block 21. During the process of placing the rotors in the placement groove 211, the iron cores on the rotors come into contact with the abutment part 252 through the inclined part 253. When the rotor iron cores come into contact with the placement groove 211, the robotic arm 5 releases. Then, the laser welding device welds the copper ring. After the upper side is welded, the robotic arm 5 clamps the rotors and lifts them up. Then, it is rotated 180° and placed in the placement groove 211. The laser welding device welds the other side of the copper ring. After the welding is complete, the robotic arm 5 grabs the two rotors and places them on the inclined track. The rotor iron cores are located in the track groove 31, and the rotors roll down on the inclined track.
