Description

Technical Field

[0001] This utility model relates to the field of welding clamping technology, specifically a copper busbar welding clamping mechanism. Background Technology

[0002] Copper busbars generally refer to copper busbars, which are a major type of copper processed materials. Copper busbars have high mechanical properties, good electrical and thermal conductivity, excellent corrosion resistance, electroplating and brazing properties, beautiful appearance and good forming and processing performance. Therefore, various power transmission and transformation equipment and electrical equipment made of them have been widely used in the power field. In the process of connecting copper busbars, welding of copper busbars is required, which requires the use of clamping structures.

[0003] Traditional copper busbar welding clamping mechanisms still exist in use. Two copper busbars to be welded are connected together by the clamping mechanism. After the welding process is completed, due to the large amount of residual welding heat on the surface of the copper busbar, the operator cannot disassemble it by hand. Although auxiliary tools such as heat-insulated pliers and clamps can be used, the use of these tools is cumbersome. Not only is it necessary to accurately align the clamping part, but it is also necessary to repeatedly adjust the force angle to avoid damaging the copper busbar or affecting the welding quality. This complicated disassembly process greatly extends the processing time of a single workpiece. The frequent tool switching and operation steps significantly reduce the overall operating efficiency of the production line. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a copper busbar welding clamping mechanism. This solves the problem that traditional copper busbar welding clamping mechanisms still have issues during use. When two copper busbars to be welded are connected by the clamping mechanism, after the welding process is completed, a large amount of residual welding heat remains on the surface of the copper busbars, making it impossible for operators to disassemble them by hand. Although auxiliary tools such as heat-insulated pliers and clamps can be used, these tools are cumbersome to use. They require precise alignment of the clamping points and repeated adjustments of the force angle to avoid damaging the copper busbars or affecting the welding quality. This complex disassembly process significantly extends the processing time for a single workpiece, and the frequent tool switching and overlapping operation steps significantly reduce the overall operating efficiency of the production line.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a copper busbar welding clamping mechanism, comprising an outer frame, a housing inside the outer frame, a support block fixedly connected to the inner wall of the housing, a clamping device on the inner wall of the housing, a collection box slidably engaged with the top of the outer frame, and a disassembly device on the inner wall of the outer frame, the disassembly device comprising: multiple springs, all fixedly connected to the inner wall of the outer frame; multiple rollers, all slidably engaged with the inner wall of the outer frame; multiple connecting frames, each rotatably connected to the outer wall of the rollers via bearings, and all fixedly connected to the outer wall of the housing; a sliding rod fixedly connected to the outer wall of the housing and in contact with the inner wall of the outer frame; and a sliding sleeve slidably engaged with the outer wall of the sliding rod; wherein, when the sliding sleeve is pulled upward, the sliding sleeve is no longer engaged with the inner wall of the outer frame, pushing the sliding sleeve to move the housing below the sliding rod, the housing compresses the spring, and simultaneously the housing moves the clamped copper busbar, at which point the support block pushes the copper busbar down.

[0006] Preferably, a support leg is fixedly connected to the bottom of the outer frame, and a collection box is attached to the top of the support leg.

[0007] Preferably, two limiting blocks are fixedly connected to the top of the housing, and the outer walls of the two limiting blocks are slidably engaged with the inner wall of the outer frame.

[0008] Preferably, the clamping device includes: a bidirectional lead screw, rotatably connected to the inner wall of the housing via a bearing; a handle, fixedly connected to one end of the bidirectional lead screw; two sliding plates, each threadedly connected to the outer wall of the bidirectional lead screw and slidably engaged with the inner wall of the housing; two clamping plates, each slidably engaged with the inner wall of one of the two sliding plates; and two threaded rods, each rotatably connected to the inner wall of the sliding plate via a bearing and threadedly connected to the inner wall of the two clamping plates. Twisting the threaded rods causes the clamping plates to move downwards, cooperating with the sliding plates to clamp and fix the copper busbar to be welded. Twisting the handle causes the two sliding plates to move inwards via the bidirectional lead screw, and the two sliding plates connect the two fixed copper busbars together, facilitating welding of the copper busbars.

[0009] Preferably, the inner wall of the collection box is provided with a recycling device, which includes: an air pump fixedly connected to the inner wall of the collection box; a filter plate fixedly connected to the inner wall of the collection box; and an air inlet connected to the inside of the collection box on the side away from the air pump. When the air pump is working, it discharges the gas inside the collection box to the outside, and the inside of the collection box is briefly in a negative pressure state. External air and dust enter the interior of the air inlet. After the air and dust pass through the filter plate, the dust is filtered out by the filter plate, preventing the dust from polluting the surrounding air.

[0010] Beneficial effects

[0011] This utility model provides a copper busbar welding clamping mechanism. It has the following advantages: the support legs of this copper busbar welding clamping mechanism make the outer frame more stable during use, and the support blocks increase the strength of the outer frame. The welded copper busbar is removed from the clamping device using a disassembly device in conjunction with the support blocks, allowing it to fall into a collection box for unified collection. During the transfer of the welded copper busbar, no heat-insulating pliers are needed, improving the disassembly efficiency of the copper busbar, shortening the processing time for a single workpiece, and improving the operating efficiency of the production line.

[0012] The workpiece is clamped and fixed by a clamping mechanism, and the fumes generated during copper busbar welding are recovered by a recycling device to prevent the fumes from spreading outward and polluting the surrounding air. At the same time, the filter plate is fixed inside the collection box with bolts, making it easy to remove and replace the filter plate. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0021] Traditional copper busbar welding clamping mechanisms still exist in use. Two copper busbars to be welded are connected together by the clamping mechanism. After the welding process is completed, due to the large amount of residual welding heat on the surface of the copper busbar, the operator cannot disassemble it by hand. Although auxiliary tools such as heat-insulated pliers and clamps can be used, the use of these tools is cumbersome. Not only is it necessary to accurately align the clamping part, but it is also necessary to repeatedly adjust the force angle to avoid damaging the copper busbar or affecting the welding quality. This complicated disassembly process greatly extends the processing time of a single workpiece. The frequent tool switching and operation steps significantly reduce the overall operating efficiency of the production line.

[0022] In view of this, the present invention provides a copper busbar welding clamping mechanism, which has the following beneficial effects.

[0023] Example 1: By Figure 1 , 2 As can be seen from points 3, 4, and 5, a copper busbar welding clamping mechanism includes an outer frame 1, a housing 3 inside the outer frame 1, a support block 5 fixedly connected to the inner wall of the housing 3, a clamping device 4 on the inner wall of the housing 3, a collection box 7 slidably engaged with the top of the outer frame 1, and a disassembly device 2 on the inner wall of the outer frame 1. The disassembly device 2 includes: multiple springs 21, all fixedly connected to the inner wall of the outer frame 1; multiple rollers 23, all slidably engaged with the inner wall of the outer frame 1; and multiple connecting frames 22, respectively... The roller 23 is rotatably connected to the outer wall of the bearing and is fixedly connected to the outer wall of the housing 3; the slide rod 24 is fixedly connected to the outer wall of the housing 3 and fits against the inner wall of the outer frame 1; the slide sleeve 25 is slidably engaged with the outer wall of the slide rod 24; when the slide sleeve 25 is pulled upward, the slide sleeve 25 is no longer engaged with the inside of the outer frame 1, and the slide sleeve 25 is pushed to move the housing 3 below the slide rod 24. The housing 3 compresses the spring 21, and at the same time, the housing 3 drives the clamped copper busbar to move. At this time, the support block 5 pushes the copper busbar down.

[0024] In the specific implementation process, it is worth noting that the support block 5 increases the strength of the outer frame 1, pulls the sliding sleeve 25 to move upward and no longer engages with the inside of the outer frame 1, pushes the sliding rod 24 inside the sliding sleeve 25 to move, the sliding rod 24 drives the lower housing 3 to move, the housing 3 compresses the spring 21, and at the same time the housing 3 drives the clamped copper busbar to move.

[0025] Furthermore, a support leg 10 is fixedly connected to the bottom of the outer frame 1, and a collection box 6 is attached to the top of the support leg 10.

[0026] In the specific implementation process, it is worth noting that the support leg 10 increases the stability of the outer frame 1, the support leg 10 limits the collection box 6, and the collection box 6 facilitates the collection of the welded copper busbars.

[0027] Furthermore, two limiting blocks 9 are fixedly connected to the top of the housing 3, and the outer walls of the two limiting blocks 9 are slidably engaged with the inner wall of the outer frame 1.

[0028] In the specific implementation process, it is worth noting that the outer frame 1 limits the shell 3 through two limiting blocks 9;

[0029] Specifically, when using this copper busbar welding clamping mechanism, the support leg 10 increases the stability of the outer frame 1 during use, the support block 5 increases the strength of the outer frame 1, and the two limit blocks 9 restrict the movement of the housing 3 through the outer frame 1. When the welded copper busbar needs to be removed, the worker pulls the sliding sleeve 25 upward to move it away from the internal engagement with the outer frame 1, pushing the sliding rod 24 inside the sliding sleeve 25 backward. The sliding rod 24, in conjunction with the roller 23, drives the housing 3 to move, compressing the spring 21. At the same time, the housing 3 drives the clamped copper busbar to move. When the clamped copper busbar... When the copper busbar contacts the support block 5, the support block 5 pushes the copper busbar down from the clamping device 4, and the copper busbar falls into the collection box 6 for centralized collection. The operator releases the spring 21 of the sliding sleeve 25, which is in a compressed state, to help the housing 3 return to its original position. The operator presses the sliding sleeve 25 to move it downward and insert it into the outer frame 1. The sliding sleeve 25, together with the sliding rod 24, fixes the housing 3 to prevent the housing 3 from moving during the welding of the copper busbar. The collection box 7 is equipped with damping between the outer frame 1. After the collection box 7 moves, it can recover the fumes generated during the welding of copper busbars at different positions.

[0030] Example 2: From Figure 1 , 2 As shown in Figure 5, the clamping device 4 includes: a bidirectional lead screw 41, rotatably connected to the inner wall of the housing 3 via bearings; a rotary handle 42, fixedly connected to one end of the bidirectional lead screw 41; two sliding plates 43, each threadedly connected to the outer wall of the bidirectional lead screw 41 and slidably engaged with the inner wall of the housing 3; two clamping plates 44, each slidably engaged with the inner wall of the two sliding plates 43; and two threaded rods 45, each rotatably connected to the inner wall of the sliding plates 43 via bearings and threadedly connected to the inner wall of the two clamping plates 44. Twisting the threaded rods 45 causes the clamping plates 44 to move downwards, cooperating with the sliding plates 43 to clamp and fix the copper busbar to be welded. Twisting the rotary handle 42 causes the two sliding plates 43 to move inwards via the bidirectional lead screw 41, connecting the two fixed copper busbars together, facilitating welding of the copper busbars.

[0031] In the specific implementation process, it is worth noting that the shell 3 restricts the sliding plate 43 to move only in the horizontal direction, the sliding plate 43 restricts the clamping plate 44 to move only in the vertical direction, the twisting of the threaded rod 45 drives the clamping plate 44 to move downward, the clamping plate 44 cooperates with the sliding plate 43 to clamp and fix the copper busbar to be welded, the twisting of the swivel 42 drives the two sliding plates 43 to move inward through the double screw 41, the two sliding plates 43 drive the two fixed copper busbars to connect together;

[0032] Specifically, based on the above embodiment one, when it is necessary to clamp and fix two copper busbars, when the copper busbar to be welded is placed inside the clamping plate 44 and the sliding plate 43, the worker twists the threaded rod 45 to move the clamping plate 44 downward. The clamping plate 44 cooperates with the sliding plate 43 to clamp and fix the copper busbar to be welded. Twisting the handle 42 drives the two sliding plates 43 to move inward through the double-ended screw 41. The two sliding plates 43 drive the two fixed copper busbars to connect together, which facilitates the welding of the copper busbars. Twisting the two threaded rods 45 in the opposite direction drives the two clamping plates 44 to move upward. The two clamping plates 44 no longer cooperate with the two sliding plates 43 to fix the welded copper busbars.

[0033] Example 3: From Figure 1 and 3 It is known that the inner wall of the collection box 7 is provided with a recycling device 8, which includes: an air pump 81, fixedly connected to the inner wall of the collection box 7; a filter plate 82, fixedly connected to the inner wall of the collection box 7; and an air inlet 83, which is connected to the inside of the collection box 7 away from the air pump 81. When the air pump 81 is working, it discharges the gas inside the collection box 7 to the outside, and the inside of the collection box 7 is briefly in a negative pressure state. External air and dust enter the inside of the air inlet 83. After the air and dust pass through the filter plate 82, the dust is filtered out by the filter plate 82 to prevent the dust from polluting the surrounding air.

[0034] In the specific implementation process, it is worth noting that the mesh size of the filter plate 82 is not limited, as long as it meets the usage requirements. When the air pump 81 is working, it discharges the gas inside the collection box 7 to the outside. The outside air, along with the smoke and dust, enters the collection box 7 through the air inlet 83 under the influence of air pressure. The filter plate 82 filters out the smoke and dust in the air.

[0035] Specifically, based on the above embodiment one, the staff controls the air pump 81 to work through the external control panel. The air pump 81 discharges the air inside the collection box 7 to the outside. The inside of the collection box 7 is in a negative pressure state. The air pressure inside the collection box 7 is small. The larger external air pressure draws the outside air along with the smoke and dust into the collection box 7 through the air inlet 83. When the air passes through the filter plate 82, the filter plate 82 adsorbs the smoke and dust, preventing the smoke from spreading into the surrounding air and causing pollution to the surrounding air.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
