Description

Technical Field

[0001] This utility model relates to the field of switchgear, specifically to a tooling for processing copper busbars in switchgear. Background Technology

[0002] Switchgear is a core piece of equipment in power systems used for power distribution, control, and protection. It typically consists of a metal enclosure, circuit breakers, disconnect switches, instrument transformers, busbars, secondary control components, and other integrated components. It is widely used in power plants, substations, industrial and mining enterprises, and building power distribution. Its core function is to achieve circuit on / off control, short-circuit and overload protection, voltage and current monitoring, and power metering through the coordinated operation of its internal components, ensuring the safe and stable operation of the power system.

[0003] The copper busbar in switchgear is a core conductive component for power transmission, undertaking the critical tasks of collecting, distributing, and transmitting electrical energy. Its performance directly affects the current-carrying capacity, safety, and operational stability of the switchgear. The processing of copper busbars mainly includes steps such as blanking and straightening, punching and bending, welding and silver plating, and insulation treatment and testing. For example, the invention patent with application number CN202310284391.3, entitled "Copper Busbar Punching Device," uses air pressure to press the top of the copper busbar into a positioning groove. Simultaneously, the sleeve and pressure plate on the outside of the pressure rod contact the copper busbar first before punching, pressing the top of the copper busbar. Combined with the clamping effect of the air pressure difference, this ensures a stable positioning and fixation of the copper busbar during punching. Furthermore, the sequence of positioning before punching and finally punching deformation ensures that when the middle of the copper busbar is deformed under pressure, the punched ends of the copper busbar are stably pressed. However, this device has poor processing efficiency for copper busbars. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling for processing copper busbars in switchgear, which aims to improve the poor processing efficiency of conventional copper busbar processing tooling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A switchgear copper busbar processing fixture includes a base plate, on which at least one pushing mechanism is provided. A support assembly is fixed on the base plate, and the support assembly is disposed on both sides of the pushing mechanism. The end of the support assembly is provided with an upwardly extending limiting protrusion. The driving end of the pushing mechanism faces the limiting protrusion and is driven to connect a top block. The copper busbar is placed on the support assembly. The pushing mechanism drives the top block to abut against one end of the copper busbar, and the other end of the copper busbar abuts against the limiting protrusion.

[0006] Furthermore, the pushing mechanism includes a driving unit, which is fixed on the bottom surface of the substrate and drives a driving block through the substrate. The driving block has inclined wedge driving surfaces on both sides, and the inclined wedge driving surfaces are inclined inward from the top end of the driving block to the bottom center of the driving block. One side of the top block is provided with a wedge-shaped mating surface, which is inclined outward from the top surface of the top block to the bottom surface of the top block.

[0007] Furthermore, a "T"-shaped groove is formed on the wedge-shaped mating surface, and the extending direction of the "T"-shaped groove is the same as the extending direction of the wedge-shaped mating surface; Limiting grooves are provided on the other two sides of the drive block, and the open end of the "T"-shaped groove is embedded in the limiting groove.

[0008] Furthermore, the support assembly includes an outer support rod and an inner support rod arranged opposite to each other. The inner support rod is disposed on one side of the pushing mechanism. The top surfaces of the inner support rod and the outer support rod are located on the same extension plane. The two ends of the copper busbar are respectively pressed onto the outer support rod and the inner support rod. The limiting protrusion is located on the side of the outer support rod away from the jacking mechanism.

[0009] Furthermore, the support assembly is provided with positioning elements, which are located on both sides of the pushing mechanism; The positioning element includes a side positioning portion extending to both sides and an end positioning portion located in the middle. The side positioning portion corresponds to the side position of the copper busbar, and the end positioning portion extends towards the pushing mechanism and corresponds to the end position of the copper busbar.

[0010] Furthermore, the side positioning part and the end positioning part are provided with a guide slope on the side facing the copper busbar, and the guide slope slopes outward from the middle of the top surface of the positioning part to the bottom surface.

[0011] Furthermore, the inner support rod is provided with a first fixing hole, and the positioning member is provided with a third fixing hole. The third fixing hole corresponds one-to-one with the first positioning hole, and a connecting member is provided. The connecting member base plate is fixedly connected.

[0012] Furthermore, positioning grooves are provided on the top surfaces of both the outer and inner support rods, and the two ends of the bottom surface of the copper busbar are embedded in the positioning grooves.

[0013] Furthermore, one end of the copper busbar is provided with a punched hole, which is located on the side of the copper busbar near the inner support rod, and one side of the inner support rod extends to the side of the punched hole.

[0014] Furthermore, one end of the copper busbar is provided with a punched hole, which is located on the side of the copper busbar near the inner support rod. One side of the inner support rod extends to below the punched hole, and a clearance notch is provided on the inner support rod. The clearance notch corresponds one-to-one with the punched hole and they are interconnected.

[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art: The support assembly supports the copper busbar. The push mechanism in the middle drives the top block to push one end of the copper busbar, so that the other end of the copper busbar abuts against the limiting protrusion, thereby limiting the copper busbar and facilitating the punching process. The support assembly is located on both sides of the push mechanism, enabling simultaneous limiting processing of 2n copper busbars, effectively improving processing efficiency.

[0022] Please refer to Figures 1-7 As shown, this embodiment provides a copper busbar processing fixture for a switchgear, including a base plate 1. At least one pushing mechanism 2 is provided on the base plate 1, and a support component 3 is fixed on the base plate 1. The support component 3 is disposed on both sides of the pushing mechanism 2, and the end of the support component 3 is provided with an upwardly extending limiting protrusion 311. The driving end of the pushing mechanism 2 faces the limiting protrusion 311 and is driven to connect a top block 23. The copper busbar 7 is placed on the support component 3. The pushing mechanism 2 drives the top block 23 to abut against one end of the copper busbar 7, and the other end of the copper busbar 7 abuts against the limiting protrusion 311.

[0023] The support component 3 supports the copper busbar 7. The push mechanism 2 located in the middle drives the top block 23 to push one end of the copper busbar 7, so that the other end of the copper busbar 7 abuts against the limiting protrusion 311, thereby limiting the copper busbar 7 and facilitating the punching process of the copper busbar 7. The support component 3 is located on both sides of the push mechanism 2, so that 2n copper busbars 7 can be limited at the same time, effectively improving the processing efficiency.

[0024] Please refer to Figures 1-4 As shown, specifically, the pushing mechanism 2 includes a driving unit 21, which is fixed to the bottom surface of the substrate 1 and drives a driving block 22 through the substrate 1. The driving block 22 has inclined wedge driving surfaces 221 on both sides, with the top end of the inclined wedge driving surface 221 tilting inwards to the middle of the bottom of the driving block 22. The top block 23 has an inclined wedge contact surface 231 on one side, with the top surface of the inclined wedge contact surface 231 tilting outwards to the bottom surface of the top block 23. In this embodiment, the driving unit 21 is a driving motor, which is fixed to the bottom surface of the substrate 1. The drive end of the drive motor passes through the substrate 1 and connects to the drive block 22, driving the drive block 22 to perform reciprocating linear motion in the vertical direction. The drive block 22 and the top block 23 are mutually attached through the wedge driving surface 221 and the wedge contact surface 231. During the movement, the drive block 22 pushes the top block 23 to abut the end of the copper busbar 7. The drive block 22 is a block that is smaller at the bottom and larger at the top. The two sides of the drive block 22 are effectively utilized to realize the simultaneous driving action of the two top blocks 23, thereby improving processing efficiency.

[0025] Please refer to Figure 4 As shown, a "T"-shaped groove 232 is further provided on the wedge-fitting surface 231, and the extending direction of the "T"-shaped groove 232 is the same as the extending direction of the wedge-fitting surface 231. Limiting grooves 222 are provided on the other two sides of the driving block 22, and the open end of the "T"-shaped groove 232 is embedded in the limiting groove 222. The inclined wedge driving surface 221 of the drive block 22 fits against the bottom of the "T" shaped groove 232. The open end of the "T" shaped groove 232 is embedded in the limiting groove 222, realizing the movable connection between the drive block 22 and the top block 23, improving the accuracy of the movement path of the top block 23. During the descent of the drive block 22, it ensures that the top block 23 can move stably toward the copper busbar 7, providing the copper busbar 7 with a pushing force toward the limiting protrusion 311, thus improving the limiting effect on the copper busbar 7. During the ascent of the drive block 22, the drive block 22 applies a pulling force to the top block 23 away from the limiting protrusion 311, driving the top block 23 to reset, which facilitates the loading and unloading of the copper busbar 7 and further improves processing efficiency.

[0026] Please refer to Figure 3As shown, specifically, the support assembly 3 includes an outer support rod 31 and an inner support rod 32 arranged opposite to each other, with the inner support rod 32 located on one side of the pushing mechanism 2. The top surfaces of the inner support rod 32 and the outer support rod 31 are located on the same extended plane, and the two ends of the copper busbar 7 are respectively pressed onto the outer support rod 31 and the inner support rod 32. A limiting protrusion 311 is located on the side of the outer support rod 31 away from the pushing mechanism 2. The top surfaces of the inner support rod 32 and the outer support rod 31 form a support plane to support the two ends of the bottom surface of the copper busbar 7, and the rod structure supports the copper busbar 7. While ensuring the support effect, compared with the plate structure supporting the copper busbar 7, it effectively reduces the overall weight of the tooling. Furthermore, the gap between the inner support rod 32 and the outer support rod 31 forms a waste collection space, which facilitates the collection and treatment of waste generated during the punching or other processing of the copper busbar 7.

[0027] A shim plate 11 is fixed on the substrate 1, and a top block 23 is movably mounted on the shim plate 11. The shim plate 11 elevates the top block 23 to ensure that the top block 23 and the copper busbar 7 are located on the same horizontal extension surface, and to ensure that the top block 23 can stably abut against the end of the copper busbar 7.

[0028] Please refer to Figure 3 and Figure 5 As shown, furthermore, the support assembly 3 is provided with positioning elements 4, which are located on both sides of the pushing mechanism 2. The positioning elements 4 include side positioning portions 41 extending to both sides and end positioning portions 42 located in the middle. The side positioning portions 41 correspond to the side positions of the copper busbar 7, and the end positioning portions 42 extend towards the pushing mechanism 2 and correspond to the end positions of the copper busbar 7. The side positioning portions 41 of the positioning elements 4 extend to the support assemblies 3 on both sides of the pushing mechanism 2 to limit the sides of the copper busbar 7 on both sides of the pushing mechanism 2. The side positioning portions 41 apply limiting forces to both sides of the copper busbar 7. The pushing mechanism 2, the end positioning portions 42, and the limiting protrusions 311 apply limiting forces to both ends of the copper busbar 7, forming a four-sided limiting structure, which makes the copper busbar 7 have good stability during processing and improves the processing accuracy of the copper busbar 7.

[0029] The side positioning part 41 and the end positioning part 42 are provided with guide slopes 43 facing the copper busbar 7. The guide slopes 43 slope outward from the middle of the top surface of the positioning part 4 to the bottom surface. The guide slopes 43 guide the bottom end of the copper busbar 7 to ensure that the copper busbar 7 can be accurately placed in the processing position, thereby further improving the processing accuracy of the copper busbar 7.

[0030] The inner support rod 32 has a first fixing hole 321, the shim plate 11 has a second fixing hole 111, and the positioning member 4 has a third fixing hole 44 and a fourth positioning hole 45. The third fixing hole 44 and the fourth positioning hole 45 correspond one-to-one with the first positioning hole and the second positioning hole, respectively. A connector (not shown in the attached figure) is provided, and the connector base plate 1 is fixedly connected to it. In this embodiment, the connector is a bolt, which passes through the positioning member 4, the inner support rod 32, the shim plate 11, and the base plate 1 for fixed connection, effectively reducing the number of connectors and reducing costs.

[0031] Furthermore, positioning grooves 312 are provided on the top surfaces of both the outer support rod 31 and the inner support rod 32, and the two ends of the bottom surface of the copper busbar 7 are embedded in the positioning grooves 312. The guide slope 43 guides the copper busbar 7 to ensure that the copper busbar 7 can be stably positioned in the positioning groove 312. The positioning groove 312 further positions the copper busbar 7 to ensure the accuracy of the processing position of the copper busbar 7.

[0032] Please refer to Figure 2 and Figure 6 As shown, in this embodiment, one end of the copper busbar 7 is provided with a punching position 71, which is located on the side of the copper busbar 7 near the inner support rod 32. One side of the inner support rod 32 extends to the side of the punching position 71. The inner support rod 32 is set with a smaller width to make way for the punching position 71 while ensuring the support effect, so as to ensure that the hole processing tool can completely penetrate the copper busbar 7 and improve the punching effect.

[0033] Please refer to Figure 7 As shown, similarly, in another embodiment, one end of the copper busbar 7 is provided with a punched hole 71, located on the side of the copper busbar 7 near the inner support rod 32. One side of the inner support rod 32 extends below the punched hole 71, and a clearance notch 322 is provided on the inner support rod 32. The clearance notch 322 corresponds one-to-one with the punched hole 71 and is interconnected. Increasing the width of the inner support rod 32 provides a larger area of ​​support for one end of the copper busbar 7, effectively improving the support effect. At the same time, the clearance notch 322 is provided to allow space for the punched hole 71, avoiding interference with the hole-making tool and affecting the punching process.

[0034] Please refer to Figure 1 As shown, the processing fixture for the copper busbar 7 of the switchgear further includes a base plate 5, on which a support column 6 is fixed. The base plate 1 is fixed on the support column 6, which supports the base plate 1 and provides installation space for the drive motor. The base plate 5 supports the base plate 1, which facilitates the transfer of the base plate 1 and improves the efficiency of processing steps.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
