Description

Technical Field

[0001] The present invention relates to the field of battery cabinet production, and particularly to a welding device for battery cabinet production. Background Technique

[0002] A battery cabinet is a special device for storing and managing battery packs, which is widely used in energy storage systems, data centers, communication base stations, new energy power stations, electric vehicle charging stations and other fields. It usually adopts a high-strength steel or aluminum alloy frame and is made by welding.

[0003] A plasma arc welding machine is a high-precision device that uses a high-temperature plasma arc as a heat source for welding. It is suitable for the production and processing of battery cabinets. By compressing the arc, a plasma arc with a high energy density is formed to weld the frame of the battery cabinet. In order to reduce the high temperature generated during welding, it is necessary to quickly conduct heat through a cooling rack or a water-cooling channel to prevent the workpiece from overheating. The existing welding device will set two heat-conducting blocks on the outside of the welding head. When the welding head returns upward, the two blocks clamp the welding head, and the heat on the surface of the welding head is conducted into the coolant through liquid cooling to achieve the cooling of the welding head. However, when welding different plates, different types of welding heads need to be replaced, and the blocks need to be replaced correspondingly, otherwise the clamping and heat dissipation of the welding head cannot be achieved, and the operation is relatively troublesome.

A sleeve 33 is fixedly installed on the side of the L-shaped sliding plate 14 close to the support plate 10. A chute for the sleeve 33 to be inserted and slidably limited is opened on the outer side of the support plate 10, and a first guide rod 34 slidably penetrating through the sleeve 33 is fixedly installed on the inner side of the chute, so that the L-shaped sliding plate 14 can drive the sleeve 33 to move along the outer side of the first guide rod 34, improving the smoothness of the movement of the L-shaped sliding plate 14. Slide rollers 35 are fixedly installed on the opposite sides of the two support plates 10.

A contact plate 25 is fixedly installed between the two moving plates 22, so that when the two heat dissipation covers 7 approach each other, the contact plates 25 on the two docking pipes 18 can contact each other, and the contact plate 25 pushes the moving plate 22 to move. A slider 26 is fixedly installed on the side of the moving plate 22 close to the sleeve block 21. A sliding cavity for the slider 26 to slide and be limited is opened on the outer side of the sleeve block 21.

An exhaust box 38 is fixedly installed inside the heat dissipation cover 7. The exhaust box 38 has an arc-shaped structure. The docking pipe 18 on the cold air pipe 9 extends into the exhaust box 38, so that the cold air pipe 9 injects cold air into the exhaust box 38 through the docking pipe 18. A plurality of exhaust nozzles 39 are fixedly installed on the side of the exhaust box 38 away from the heat dissipation cover 7, so that the cold air is evenly sprayed on the outside of the welding head 6.

[0024] Embodiment 3: Please refer to Figure 2 and Figure 8, this embodiment further illustrates other embodiments. The disassembly and assembly mechanism in the figure includes a card frame 28 fixedly installed on the outside of the support plate 10. The end of the card frame 28 is in an L-shaped structure. An installation groove for the card frame 28 to be limited and inserted is provided on the outside of the operation frame 2. Three card blocks 29 are rotatably installed on both sides of the operation frame 2. The side of the card block 29 close to the operation frame 2 is in contact with the outside of the support plate 10. The card block 29 abuts against the outside of the support plate 10, so that the card frame 28 on the support plate 10 abuts in the installation groove of the operation frame 2, realizing the rapid assembly of the support plate 10. A handwheel 30 is fixedly installed on the side of the card block 29 away from the support plate 10, which is used to rotate the card block 29 to facilitate the assembly and disassembly of the support plate 10. One end of two screws 11 close to the left side of the operation frame 2 is fixedly installed with a rhombic block 31. One end of the two screws 11 close to the right side of the operation frame 2 is provided with a rhombic groove for the rhombic block 31 to be limited and inserted. When the support plate 10 and the operation frame 2 are assembled, the rhombic blocks 31 on the two screws 11 can be inserted into the rhombic grooves on the other two screws 11, providing support for the end of the screw 11 away from the support plate 10, facilitating the stable rotation of the screw 11, and facilitating the assembly and disassembly.

[0025] Working principle: First, the operator starts the electric telescopic rod 4 by operating the frame 2, so that the electric telescopic rod 4 pushes the welding head 6 to move onto the workpiece to be welded. The welding head 6 can then weld the workpiece. After welding is completed, the operator starts the electric telescopic rod 4, causing the electric telescopic rod 4 to drive the welding head 6 and the two arc-shaped bars 12 to move upward. The arc-shaped bars 12 drive the L-shaped slide plate 14 to move synchronously, so that the first rack 16 on the L-shaped slide plate 14 contacts the first gear 15 on the screw rod 11. The first gear 15 can then drive the screw rod 11 to rotate, causing the four screw rods 11 to drive the corresponding moving blocks 17 to move. The four moving blocks 17 drive the two heat dissipation covers 7 to approach each other, so that the heat dissipation covers 7 cover the welding head 6. At the same time, the heat dissipation covers 7 drive the docking pipes 18 to move synchronously, so that the docking pipes 18 drive the sliders 26 to move through the sleeve blocks 21. The sliders 26 can then drive the contact plates 25 to move through the moving plates 22, causing the contact plate 25 on the left side of the welding head 6 to contact the contact plate 25 on the right side of the welding head 6. The contact plate 25 can then push the moving plate 22 to move. The moving plate 22 drives the slider 26 to move along the sliding cavity of the sleeve block 21, so that the second rack 23 on the moving plate 22 drives the second gear 24 on the positioning rod 20 to rotate. The second gear 24 can then drive the sealing disc 19 to rotate through the positioning rod 20, so that the sealing disc 19 opens the docking pipe 18. Then, the operator starts the heat exchanger 3. The heat exchanger 3 injects cold air into the cold air pipe 9, so that the cold air pipe 9 injects cold air into the exhaust box 38 through the docking pipe 18. The cold air can then be discharged from the exhaust nozzles 39 on the exhaust box 38, so that the cold air can be evenly sprayed on the outside of the welding head 6. At the same time, the heat dissipation pipes 8 timely discharge the hot air in the heat dissipation covers 7. Thus, the cooling of the welding head 6 is achieved, and the welding head 6 of various sizes can be dissipated heat, thereby achieving the effect of rapid heat dissipation, facilitating the cooling treatment of the welding head 6 of more sizes, and improving the durability of the welding head 6.
