Description

Technical Field

[0001] This utility model relates to the field of welding and fixing technology for laminated copper busbars, and in particular to a flexible connection welding and fixing device for laminated copper busbars. Background Technology

[0002] Laminated copper busbars are conductive components made up of multiple layers of copper sheets stacked together. They are commonly used in power and electronic equipment to achieve efficient power transmission. During the manufacturing process of laminated copper busbars, the multiple layers of copper sheets need to be welded together.

[0003] In existing technologies, when welding multilayer copper busbars, workers typically hold and fix the multiple copper sheets by hand, inserting one end into a welding machine for pressing and welding. This operation poses a high safety risk, and manual fixing can easily lead to inaccurate welding, thus affecting the welding effect. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a flexible welding and fixing device for laminated copper busbars.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding and fixing device for flexible connections of laminated copper busbars includes a welding machine body. An operating table is fixed on one side of the welding machine body. A fixing structure and a conveying structure are provided on the top surface of the operating table. The fixing structure includes a placement platform set on the top surface of the operating table. A mounting frame is fixed on the top surface of the placement platform. A mounting plate is slidably set on the top surface of the mounting frame. A screw is threadedly connected to the top surface of the mounting plate. A clamping plate is rotatably set at the bottom end of the screw.

[0007] As a further embodiment of this utility model, the top surface of the placement platform is provided with an installation groove, and a bidirectional lead screw is rotatably installed inside the installation groove. One end of the bidirectional lead screw passes through one side of the inner wall of the installation groove and is fixed with a handwheel. Two movable plates are slidably installed on the top surface of the placement platform, and the positive and negative threads of the bidirectional lead screw are respectively threaded to the two movable plates.

[0008] As a further embodiment of this utility model, the conveying structure includes a fixed groove formed on the top surface of the operating table, a conveying screw rotatably arranged inside the fixed groove, a movable block threadedly connected to the outer circular wall of the conveying screw, the top surface of the movable block being fixed to the bottom surface of the placement table, a motor being fixed on one side of the operating table, and the output end of the motor passing through one side of the operating table and fixed to one end of the conveying screw.

[0009] As a further embodiment of this utility model, the outer circular wall of the handwheel is provided with a number of toothed grooves, and an insert is slidably provided on one side of the placement platform, with one end of the insert being slidably inserted into the inside of the toothed groove.

[0010] As a further embodiment of this utility model, a guide rod is fixed inside the fixing groove, and the guide rod is slidably inserted into the interior of the movable block.

[0011] As a further embodiment of this utility model, the top surface of the mounting bracket is fixed with two T-shaped blocks, and the bottom surface of the mounting plate is provided with two T-shaped grooves, with the T-shaped blocks and the T-shaped grooves slidingly disposed inside each other.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This fixing device, through the setting of a fixing structure and a conveying structure, uses a bidirectional screw to rotate, causing two movable plates to move closer together and clamp the busbar with appropriate force, keeping the multi-layer copper sheets aligned. The screw drives the pressure plate to move downward, pressing and fixing the multi-layer copper sheets. The motor drives the conveying screw to rotate, which moves the placement table into the welding machine body. The fixed busbar enters the welding machine body for pressure welding, eliminating the need for workers to hold the multi-layer copper sheets for welding, thus improving the safety and welding effect of busbar welding.

[0022] like Figures 1-4 As shown, a welding and fixing device for flexible connections of laminated copper busbars includes a welding machine body 1. An operating table 2 is fixed on one side of the welding machine body 1. The top surface of the operating table 2 is provided with a fixing structure and a conveying structure. The fixing structure includes a placement platform 201 set on the top surface of the operating table 2. A mounting frame 202 is fixed on the top surface of the placement platform 201. A mounting plate 203 is slidably arranged on the top surface of the mounting frame 202. A screw 204 is threadedly connected to the top surface of the mounting plate 203. A clamping plate 205 is rotatably arranged at the bottom end of the screw 204.

[0023] In this embodiment, the top surface of the placement platform 201 is provided with a mounting groove 206, and a bidirectional lead screw 207 is rotatably installed inside the mounting groove 206. One end of the bidirectional lead screw 207 passes through one side of the inner wall of the mounting groove 206 and is fixed with a handwheel 208. Two movable plates 209 are slidably installed on the top surface of the placement platform 201, and the positive and negative threads of the bidirectional lead screw 207 are threadedly connected to the two movable plates 209 respectively.

[0024] In this embodiment, the conveying structure includes a fixed groove 3 on the top surface of the operating table 2. A conveying screw 301 is rotatably mounted inside the fixed groove 3. A movable block 302 is threadedly connected to the outer circular wall of the conveying screw 301. The top surface of the movable block 302 is fixed to the bottom surface of the placement platform 201. A motor is fixed to one side of the operating table 2. The output end of the motor passes through one side of the operating table 2 and is fixed to one end of the conveying screw 301. With the setting of the fixed structure and the conveying structure, the operator inserts one end of the busbar to be welded into the mounting bracket 202, so that the welding end of the busbar passes through the range of the two movable plates 209. The operator rotates the handwheel 208 to rotate the bidirectional screw 207. The motor moves two movable plates 209 closer together, clamping the busbar with appropriate force to keep the multi-layer copper sheets aligned. Then, the operator rotates the screw 204, causing the screw 204 to move the clamping plate 205 downwards. The clamping plate 205 moves downwards to press and fix the multi-layer copper sheets. Finally, the operator starts the motor, which drives the conveying screw 301 to rotate. The conveying screw 301 moves the placement platform 201 into the welding machine body 1 through the movable block 302. The fixed busbar follows the placement platform 201 into the welding machine body 1 for pressing and welding. This eliminates the need for the operator to hold the multi-layer copper sheets while welding, improving the safety and welding effect of the busbar welding.

[0025] In this embodiment, the outer circular wall of the handwheel 208 is provided with a plurality of toothed grooves 4, and an insert 401 is slidably provided on one side of the placement platform 201. One end of the insert 401 is slidably inserted into the inside of the toothed groove 4. When the operator drives the bidirectional lead screw 207 to rotate by the handwheel 208, the operator can insert the insert 401 into the toothed groove 4, thereby limiting the position of the handwheel 208 and the bidirectional lead screw 207 after rotation and preventing the movable plate 209 from shifting.

[0026] In this embodiment, a guide rod 5 is fixed inside the fixed groove 3. The guide rod 5 is slidably inserted into the interior of the movable block 302. The guide rod 5 can limit and guide one end of the placement platform 201, making its movement more stable.

[0027] In this embodiment, two T-shaped blocks 6 are fixed on the top surface of the mounting bracket 202, and two T-shaped grooves 601 are opened on the bottom surface of the mounting plate 203. The T-shaped blocks 6 and the T-shaped grooves 601 are slidably arranged inside, and the mounting plate 203 can be firmly connected to the mounting bracket 202 when sliding through the T-shaped blocks 6 and the T-shaped grooves 601.

[0028] Working principle: In use, the operator inserts one end of the busbar to be welded into the mounting bracket 202, ensuring that the welding end of the busbar extends beyond the range of the two movable plates 209. The operator then turns the handwheel 208, causing the bidirectional lead screw 207 to rotate and move the two movable plates 209 closer together, clamping the busbar with appropriate force to keep the multi-layer copper sheets aligned. Next, the operator turns the screw 204, causing the pressure plate 205 to move downwards, pressing and fixing the multi-layer copper sheets. Finally, the operator starts the motor, which drives the conveying lead screw 301 to rotate. The conveying lead screw 301, through the movable block 302, drives the placement platform... 201 moves into the welding machine body 1. The fixed busbar follows the placement platform 201 into the welding machine body 1 for pressure welding. There is no need for the operator to hold the multi-layer copper sheet for welding. When the operator drives the bidirectional lead screw 207 to rotate through the handwheel 208, the operator can insert the insert 401 into the tooth groove 4 to limit the position of the handwheel 208 and the bidirectional lead screw 207 after rotation, and prevent the movable plate 209 from shifting. The guide rod 5 can limit and guide one end of the placement platform 201 to make its movement more stable. The T-block 6 and T-slot 601 can keep the mounting plate 203 firmly connected to the mounting frame 202 when sliding.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
