Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of copper busbar processing, specifically to a copper busbar anti-jump device for a distribution cabinet copper busbar processing machine. Background Technology

[0002] In the production of distribution cabinets, copper busbars are the core components for conducting current, and their processing accuracy (such as cutting and bending accuracy) directly determines the conductivity stability and safety performance of the distribution cabinet. When copper busbar processing machines (such as cutting machines and bending machines) are operating, the copper busbars need to be transported and positioned along the guide rail for processing. However, the defects of the traditional processing mode are becoming increasingly prominent: the tail end of the copper busbar is prone to severe vibration during processing, and the existing anti-jumping method that relies on manual pressing is extremely ineffective, seriously affecting processing accuracy and production efficiency.

[0003] Traditional copper busbar processing lacks a dedicated anti-jump structure: copper busbars are mostly long strips, and during processing, only the front end is fixed by a fixture, while the rear end is suspended in the air. During processing, cutting forces and bending forces cause high-frequency vibration at the rear end, which not only leads to positioning misalignment of the copper busbar, resulting in uneven cuts and bending angle deviations, but may also cause scratches on the copper busbar surface due to friction between the vibration and the machine guide rail. To suppress vibration, some companies use manual pressing of the rear end, but the manual pressing pressure is uneven and unstable, unable to adapt to the copper busbar feeding rhythm in real time, and difficult to continuously counteract the vibration impact, making the anti-jump effect negligible.

[0004] Therefore, developing a copper busbar anti-jump device for distribution cabinet copper busbar processing machines that can stably suppress vibration at the tail end of the copper busbar and replace manual pressing has become an urgent need to optimize the copper busbar processing flow and ensure product accuracy. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a copper busbar anti-jump device for a distribution cabinet copper busbar processing machine, which solves the technical problem that the tail end of the copper busbar is prone to severe vibration during the processing of the copper busbar in the prior art, and the existing anti-jump method that relies on manual pressing is extremely ineffective.

[0006] According to one aspect, at least one embodiment of this disclosure provides a copper busbar anti-jump device for a distribution cabinet copper busbar processing machine, comprising: A base plate and a top frame, wherein the top frame is fixed to the base plate; A support conveyor assembly is disposed on the base plate; A straightening and clamping assembly is disposed on the base plate and the top frame; The corrective clamping assembly includes a pair of movable frames, each of which is horizontally slidably connected to both ends of the base plate surface. Several side push rods are fixedly connected to the side ends of each movable frame, and each movable frame surface is provided with a column. A synchronous rack is horizontally installed on the upper end of each column.

[0007] As a further technical solution, a rotating shaft is vertically rotatably connected to the surface of the top frame, a transmission gear is provided at the lower end of the rotating shaft, the transmission gear meshes with a pair of synchronous racks, and a drive gear is provided at the upper end of the rotating shaft.

[0008] As a further technical solution, a telescopic cylinder is horizontally installed on the top frame, and a drive rack is provided at the output end of the telescopic cylinder. The drive rack meshes with the drive gear, and a pair of stabilizing rods are provided on the side end face of the drive rack. The stabilizing rods are horizontally slidably connected to the top of the top frame.

[0009] According to another aspect, in at least one embodiment of the present invention, the supporting conveying assembly includes a plurality of rectangular openings, all of which are formed on the surface of the base plate, and a pair of conveying rollers are horizontally rotatably connected to the rectangular openings via shafts.

[0010] As a further technical solution, one of the pair of conveying rollers is connected to a first synchronous gear via a shaft, and a synchronous shaft is provided on the side end face of the base plate. The synchronous shaft is driven to rotate by electricity, and a plurality of second synchronous gears are provided on the synchronous shaft, with the second synchronous gears meshing with the first synchronous gear respectively.

[0011] As a further technical solution, the upper surface of the conveying roller is slightly higher than the surface of the base plate, and the surface of the conveying roller is an anti-slip structure surface.

[0012] As a further technical solution, the side end face of the push rod has a stepped structure.

[0013] As a further technical solution, both the first synchronous gear and the second synchronous gear are bevel gears.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: This disclosure addresses the problem of poor anti-jumping effect of traditional manual pressing by using a corrective clamping assembly. A telescopic cylinder provides stable driving force, which, through a drive rack, drive gear, rotating shaft, and transmission gear, forms a transmission chain. This chain drives the synchronous racks on both sides to move the moving frame in opposite directions, achieving synchronous clamping of the copper busbar on both sides and preventing copper busbar displacement caused by unilateral force. The stepped side push rods at the side ends of the moving frame can adapt to copper busbars of different widths, closely fitting the side of the copper busbar and forming a reliable lateral constraint. This effectively suppresses severe vibration at the tail end of the copper busbar during processing, preventing copper busbar jumping or positioning deviation, and ensuring a smooth cut and accurate bending angle.

[0015] The stabilizing rod provides horizontal guidance for the drive rack, preventing transmission deviation and ensuring uniform and stable clamping force. The high-precision meshing of the synchronous rack and transmission gear allows the movement of the two moving frames to be completely synchronized. It also has the functions of correcting the straightness of the copper busbar and preventing jumps, replacing manual pressing, reducing labor costs, avoiding the instability of manual operation, and greatly improving processing accuracy and production efficiency, adapting to the needs of continuous copper busbar processing.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-3 As shown, it illustrates a copper busbar anti-jump device for a distribution cabinet copper busbar processing machine according to an embodiment of the present disclosure, comprising: A base plate 1 and a top frame 2, wherein the top frame 2 is fixed on the base plate 1; A support conveyor assembly 4 is disposed on the base plate 1; Correction and clamping assembly 3, which is disposed on the base plate 1 and the top frame 2; The corrective clamping assembly 3 includes a pair of movable frames 3-1, each of which is horizontally slidably connected to both ends of the base plate 1. Several side push rods 3-2 are fixedly connected to the side ends of each movable frame 3-1. Each movable frame 3-1 has a column 3-3 on its surface. A synchronous rack 3-4 is horizontally mounted on the upper end of each column 3-3. A rotating shaft 3-5 is vertically rotatably connected to the surface of the top frame 2. A transmission gear 3-6 is provided at the lower end of the rotating shaft 3-5. The transmission gear 3-6 meshes with the pair of synchronous racks 3-4. A drive gear 3-7 is provided at the upper end of the rotating shaft 3-5. A telescopic cylinder 3-8 is horizontally mounted on the top frame 2. A drive rack 3-9 is provided at the output end of the telescopic cylinder 3-8. The drive rack 3-9 meshes with the drive gear 3-7. A pair of stabilizing rods 3-10 are provided on the side end face of the drive rack 3-9. The stabilizing rods 3-10 are horizontally slidably connected to the top of the top frame 2.

[0025] In some examples, in order to achieve the centering and secure clamping of the copper busbar and avoid dimensional deviations caused by skewing or jumping during copper busbar processing, a correction and clamping assembly 3 is designed. This assembly includes a movable frame 3-1 at both ends of the surface of the base plate 1 connected to the base plate 1 through a horizontal sliding mechanism. The sliding direction is perpendicular to the copper busbar conveying direction, providing a displacement basis for the centering and alignment of the copper busbar. Several side push rods 3-2 fixed at the side ends of the movable frame 3-1 are evenly distributed along the width direction of the copper busbar. The ends of the push rods adopt an arc transition structure, which not only ensures the uniform force when pushing the copper busbar, but also avoids scratching the surface of the copper busbar. The side push rods 3-2 of the movable frame 3-1 on both sides are symmetrically arranged, which can exert force simultaneously from both ends of the copper busbar to push the copper busbar to the reference position at the center of the base plate 1.

[0026] The vertically fixed column 3-3 on the surface of the movable frame 3-1 provides installation support for the synchronous rack 3-4. The synchronous rack 3-4 is horizontally fixed to the upper end of the column 3-3, and the synchronous racks 3-4 on the two movable frames 3-1 are arranged opposite each other. The lower end of the rotating shaft 3-5 vertically rotatably connected to the surface of the top frame 2 is fitted with a transmission gear 3-6. The transmission gear 3-6 meshes with the synchronous racks 3-4 on both sides at the same time to form a synchronous transmission mechanism. When the transmission gear 3-6 rotates, it can drive the synchronous racks 3-4 on both sides to move horizontally in opposite directions, thereby driving the two movable frames 3-1 to move closer or further away synchronously, ensuring the consistency of the copper busbar being centered and aligned, and avoiding the copper busbar being skewed due to unilateral movement.

[0027] The telescopic cylinder 3-8, horizontally mounted on the top frame 2, serves as the power source. Its output end, a fixed drive rack 3-9, meshes with the drive gear 3-7 at the upper end of the rotating shaft 3-5, forming a power transmission link. When the telescopic cylinder 3-8 extends or retracts, it drives the drive rack 3-9 to slide horizontally. The drive gear 3-7 rotates accordingly and transmits power through the rotating shaft 3-5 to the transmission gear 3-6, automating the alignment of the moving frame 3-1. A pair of stabilizing rods 3-10 on the side end face of the drive rack 3-9 are fitted with the sliding sleeve on the top of the top frame 2, providing horizontal guidance for the drive rack 3-9 and preventing vertical displacement during sliding, which could lead to gear meshing failure and ensure transmission stability. With the coordinated operation of all components, the telescopic cylinder 3-8 provides power, the gear and rack achieve synchronous transmission, and the moving frame 3-1 drives the side push rod 3-2 to align and clamp the copper busbar, effectively preventing the copper busbar from slipping during processing.

[0028] like Figures 1-3 As shown in the figure, the supporting conveying assembly 4 in this embodiment includes a plurality of rectangular openings 4-1, all of which are opened on the surface of the base plate 1. A pair of conveying rollers 4-2 are horizontally rotatably connected to the rectangular openings 4-1 via shafts. One of the pair of conveying rollers 4-2 is connected to a first synchronous gear 4-3 via a shaft. A synchronous shaft 4-4 is provided on the side end face of the base plate 1. The synchronous shaft 4-4 is driven to rotate by electricity. A plurality of second synchronous gears 4-5 are provided on the synchronous shaft 4-4. The second synchronous gears 4-5 mesh with the first synchronous gears 4-3 respectively.

[0029] In some examples, in order to achieve smooth and continuous conveying of copper busbars and avoid the jumping or deviation of copper busbars caused by uneven force in traditional conveying, a support conveying assembly 4 is designed. This assembly includes several rectangular openings 4-1 evenly distributed along the copper busbar conveying direction on the surface of the base plate 1, providing installation space for the conveying rollers 4-2. A pair of conveying rollers 4-2 are arranged symmetrically up and down in the rectangular openings 4-1 and connected horizontally by a shaft. The roller spacing is adapted to the thickness of the copper busbar to form a clamping conveying structure. When the copper busbar passes between the two rollers, the friction between the roller surface and the surface of the copper busbar can drive the copper busbar to move along the conveying direction. At the same time, the double roller clamping can limit the vertical jumping of the copper busbar and provide basic support for anti-jumping.

[0030] A first synchronous gear 4-3 is fixedly mounted on the end of the shaft of the active roller in a pair of conveying rollers 4-2. The synchronous shaft 4-4, which is rotatably connected to the side end face of the base plate 1 through a bearing seat, is parallel to the copper busbar conveying direction. Several second synchronous gears 4-5 mounted on the synchronous shaft 4-4 mesh one-to-one with the first synchronous gears 4-3 in each rectangular opening 4-1, forming a centralized drive mechanism. The synchronous shaft 4-4 is connected to the electric drive device through a coupling. When the drive device is running, it drives the synchronous shaft 4-4 to rotate. Through the meshing transmission of the second synchronous gears 4-5 and the first synchronous gears 4-3, all active conveying rollers 4-2 are driven to rotate synchronously, ensuring that the linear speed of each conveying roller 4-2 is consistent, and avoiding copper busbar stretching or accumulation due to differences in conveying speed.

[0031] The surface of the conveyor roller 4-2 is knurled or coated with wear-resistant rubber to increase the friction coefficient with the copper busbar, improve the transmission efficiency of conveying power, and prevent conveying jams caused by slippage. A lubrication structure is provided at the connection between the shaft and the inner wall of the rectangular opening 4-1 to reduce rotational wear and extend the service life of the components. With the coordinated operation of all components, the synchronous shaft 4-4 achieves centralized drive, the double roller clamping ensures smooth conveying, and the enhanced friction improves power transmission, providing stable conveying support for the copper busbar. Combined with the straightening and clamping assembly 3, it completely solves the problem of processing jump-out.

[0032] For example, such as Figure 1 As shown, the upper surface of the conveying roller 4-2 is slightly higher than the surface of the base plate 1, and the surface of the conveying roller 4-2 is an anti-slip structure surface.

[0033] In some examples, the upper surface of the conveying roller 4-2 is slightly higher than the surface of the base plate 1. This design ensures that the copper busbar only contacts the conveying roller 4-2 during conveying, avoiding scratches or increased resistance caused by friction with the surface of the base plate 1, thus ensuring smooth conveying. The surface of the conveying roller 4-2 is an anti-slip structure surface, specifically formed by knurling to create a uniform textured surface, or covered with a wear-resistant rubber layer, which can significantly increase the coefficient of friction with the surface of the copper busbar.

[0034] For example, such as Figure 1 As shown, the side end face of the side push rod 3-2 has a stepped structure.

[0035] In some examples, the side push rod 3-2 has a stepped structure on its side end face. Different levels of the steps correspond to copper busbars of different widths, allowing the side push rod 3-2 to adapt to the centering and alignment requirements of various copper busbar models. When dealing with narrow copper busbars, the push rod is pushed by the inner small area end face of the step, while for wide copper busbars, the push rod is pushed by the outer large area end face, ensuring that copper busbars of different widths can be accurately pushed to the center reference position of the base plate 1.

[0036] For example, such as Figure 2 As shown, both the first synchronous gear 4-3 and the second synchronous gear 4-5 are bevel gears.

[0037] In some examples, both the first synchronous gear 4-3 and the second synchronous gear 4-5 are bevel gears. The bevel gear's conical meshing structure enables power transmission in the vertical direction of space, which is compatible with the installation layout of the synchronous shaft 4-4 (horizontally arranged) and the conveyor roller 4-2 shaft (perpendicular to the synchronous shaft 4-4). The transmission connection can be completed without additional changes to the shaft direction, making the drive structure layout on the side of the base plate 1 more compact.

[0038] In actual use: First, check the stability of the base plate 1 and the top frame 2 to ensure smooth connection between the straightening and pressing assembly 3 and the support conveying assembly 4; start the synchronous shaft 4-4 on the side end face of the base plate 1, and the synchronous shaft 4-4 is electrically driven to rotate. Through the meshing transmission of the second synchronous gear 4-5 and the first synchronous gear 4-3, the pair of conveying rollers 4-2 in the rectangular opening 4-1 are driven to rotate synchronously; place the copper busbar to be processed on the conveying roller 4-2. The anti-slip structure increases the friction. The conveying roller 4-2 is slightly higher than the surface of the base plate 1 to ensure smooth transport of the copper busbar; start the telescopic cylinder 3-8 on the top frame 2 to push the drive rack 3-9 to move horizontally. The stabilizing rod 3-10 slides along the top frame 2 to provide guidance. The drive rack 3-9 meshes with the drive gear 3-7. Rotating shaft 3-5 rotates, and transmission gear 3-6 at the lower end of rotating shaft 3-5 meshes with synchronous racks 3-4 on the two side columns 3-3, causing a pair of moving frames 3-1 to move horizontally towards each other along the base plate 1; the stepped side push rods 3-2 at the side ends of the moving frames 3-1 gradually come into contact with both sides of the copper busbar, clamping the copper busbar laterally and suppressing the tail end vibration during processing; during processing, the conveying roller 4-2 continuously drives the copper busbar forward, and the side push rods 3-2 always maintain appropriate pressure, cooperating with the processing machine to complete the cutting or bending; after processing is completed, the telescopic cylinder 3-8 resets and drives the drive rack 3-9 to move in the opposite direction, the moving frames 3-1 separate, the side push rods 3-2 release the copper busbar, the synchronous shaft 4-4 stops running, the processed copper busbar is taken out, and one processing cycle is completed.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
