Description

Technical Field

[0001] This utility model relates to the field of busbar processing technology, specifically to a processing and forming device for electrical busbar coils. Background Technology

[0002] A busbar is a shared pathway on which multiple devices are connected in parallel branches. In a power system, the busbar connects the various current-carrying branch circuits in the power distribution equipment, playing the role of collecting, distributing and transmitting electrical energy. Busbars are made of copper or aluminum, which have high current density, low resistance, and low skin effect, and do not require derating. In some cases, the busbar needs to be folded during installation.

[0003] The related technology (publication number: CN103401126B) discloses a processing and forming equipment for folding electrical busbars. The disclosed technical solution has the following characteristics: the labor intensity of workers is low during the processing, the operation level requirements of the operators are not high, the product quality is stable, and the wire clips after folding the electrical busbars are of uniform size, which is conducive to improving production efficiency and subsequent assembly quality and speed. Therefore, the present invention has the characteristics of simple structure and reasonable design.

[0004] The above-disclosed technical solutions reveal the following problems: In the traditional manual busbar folding process, the labor intensity of workers is high, which requires a high level of skill from the operators and may lead to work fatigue and low efficiency, which is not conducive to large-scale production and improving processing efficiency. If the operation is not done properly during bending, there may be safety risks, such as hand injuries. Therefore, it is necessary to ensure the stability of the busbar position during the processing. In response, we propose a new type of electrical busbar folding processing and forming equipment.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Summary of the Invention

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the problem of busbar coiling in the prior art, this utility model provides a processing and forming device for electrical busbar coiling, which combines a busbar coiling structure with a busbar positioning structure to improve the quality of the busbar coiling. The specific technical solution is as follows:

[0007] A processing and forming device for electrical busbar coils includes a processing table, a fixed column fixedly installed on the top of the processing table, a forming turntable rotatably sleeved on the outside of the fixed column, a coil limiting clip provided on the top of the fixed column, a coil member corresponding to the coil limiting clip provided on the top of the forming turntable, a rotary drive component for driving the forming turntable to rotate provided on the outer wall of the processing table, a carrier platform flush with the forming turntable provided on the outer wall of the processing table via a bracket, a pressing frame provided above the carrier platform, and a shifting component for adjusting the position of the pressing frame provided on the bracket.

[0008] In the above technical solution, positioning frames are symmetrically sleeved on both sides of the outer wall of the carrier stage, and the bracket is provided with a locking structure that drives the positioning frames to move relative to each other.

[0009] The locking structure includes a lead screw rotatably mounted on the bracket, and a displacement seat is symmetrically threaded onto the outer wall of the lead screw. The displacement seat is fixedly installed at the bottom of the positioning frame.

[0010] The bracket is provided with a guide rod parallel to the lead screw, and the displacement seat is sleeved on the outside of the guide rod.

[0011] The rotary drive component includes teeth evenly arranged circumferentially at the bottom of the outer wall of the forming turntable. An annular limiting cover fixed to the top of the processing table is fitted on the bottom of the forming turntable. A connecting groove is opened on the circumferential outer wall of the annular limiting cover. A drive gear is rotatably arranged on the outer wall of the processing table, and the drive gear meshes with the teeth after passing through the connecting groove.

[0012] The shifting assembly includes a guide frame slidably disposed on the bracket, a pressing frame fixedly installed on the top of the guide frame near the processing table, and a positioning drive assembly for driving the guide frame to move is provided on the bracket.

[0013] The support has a T-shaped guide groove on its side wall, and a T-shaped guide block that is slidably disposed in the inner cavity of the T-shaped guide groove is fixedly installed on the side wall of the guide frame.

[0014] The positioning drive assembly includes a rack fixedly mounted on the side wall of the guide frame, and the side wall of the bracket is rotatably provided with a transmission gear that meshes with the rack.

[0015] Ball bearings are evenly arranged circumferentially between the fixed column and the forming turntable.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the processing and forming device for the electrical busbar loop:

[0017] 1. After placing the busbar to be folded on the carrier table, the position of the pressure frame is adjusted by the shifting component. Then, the forming turntable is driven to rotate by the rotation drive component. The forming turntable drives the folding component on the top to fold the busbar located on the folding limit clamp. This ensures that the position of the busbar will not shift during the operation, thus guaranteeing the processing quality of the busbar folding process. The automated folding process improves the safety of the folding process.

[0018] Second, the locking structure on the bracket allows the two positioning frames to move relative to each other, which in turn drives the two vertical clamping frames to fix the busbar on the top of the carrier table. This further improves the stability of the busbar folding process, thereby avoiding busbar position deviation and improving the quality of the busbar folding process.

[0019] Third, when clamping and fixing the two sides of the busbar, the output shaft of the first motor drives the lead screw to rotate, causing the two displacement seats on the outer wall of the lead screw to drive the two positioning frames to move relative to each other, thereby fixing the busbar. The distance between the two positioning frames can be adjusted according to the specifications of the busbar, thus making it suitable for processing busbars of different specifications.

[0020] Fourth, during the busbar folding process, the output shaft of the second motor drives the drive gear to rotate, which in turn drives the forming turntable to rotate. This allows the busbar to be folded through the folding parts, thus ensuring the efficiency of the busbar folding process.

[0021] Fifth, the guide frame moves towards the loading table by means of the positioning and driving component, thereby limiting and fixing the busbar longitudinally and ensuring the stability of the busbar folding process.

[0022] 6. The output shaft of the third motor drives the transmission gear to rotate, which causes the rack meshing with the transmission gear to move the guide frame. The guide frame then drives the pressure frame to limit and fix the busbar. The position of the pressure frame can be adjusted according to the specifications of the busbar, thus making it suitable for fixing busbars of different specifications. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0031] A processing and forming device for electrical busbar loops includes a processing table 1, with a fixing post 2 fixedly mounted on the top of the processing table 1. The fixing post 2 is vertically fixed at the center of the processing table 1, and the looped end of the busbar is placed on the top of the fixing post 2. A forming turntable 3 is rotatably mounted on the top of the processing table 1, sleeved on the outside of the fixing post 2. The forming turntable 3 is movably sleeved on the outside of the fixing post 2 through a centrally opened mounting hole, so that the forming turntable 3 rotates against the outer wall of the fixing post 2. The forming turntable 3 also rotates against the top of the processing table 1.

[0032] A folded ring limiting clip 5 is provided on the top of the fixed column 2. The folded ring limiting clip 5 consists of two columns vertically fixedly installed on the top of the fixed column 2. One column is vertically fixedly installed at the center of the fixed column 2, and the other column is located at an eccentric position. There is a gap between the two columns through which the generatrix passes. A folded ring 4 corresponding to the folded ring limiting clip 5 is provided on the top of the forming turntable 3. The folded ring 4 is fixedly installed on the top of the forming turntable 3, which is at the same level as the top of the fixed column 2.

[0033] The outer wall of the processing table 1 is provided with a rotary drive component that drives the forming turntable 3 to rotate. The outer wall of the processing table 1 is provided with a carrier table 6 that is flush with the forming turntable 3 via a bracket 7. A pressing frame 9 is provided above the carrier table 6. A shifting component for adjusting the position of the pressing frame 9 is provided on the bracket 7.

[0034] After placing the busbar to be folded on the carrier stage 6, slide the busbar on the carrier stage 6 so that it passes between the two pillars of the folding limit clamp 5. Then, adjust the position of the pressure frame 9 by using the component to make the pressure frame 9 fit against the top of the busbar, thus fixing the busbar between the carrier stage 6 and the pressure frame 9. Then, drive the forming turntable 3 to rotate by the rotation drive component, so that the forming turntable 3 drives the folding member 4 on the top to fold the busbar located on the folding limit clamp 5. This ensures that the position of the busbar does not shift during the operation, guaranteeing the processing quality of the busbar folding process. The automated folding process improves the safety of the folding process.

[0035] Positioning frames 8 are symmetrically fitted on both sides of the outer wall of the carrier stage 6, and the bracket 7 is provided with a locking structure that drives the positioning frames 8 to move relative to each other. Slots are opened on the opposite surfaces of the two positioning frames 8, and the diameter of the slots corresponds to the thickness of the positioning frames 8, so that the positioning frames 8 slide against the outer wall of the positioning frame 8 through the slots. A clamping frame is vertically fixedly installed on the top of the positioning frames 8.

[0036] The locking structure on the bracket 7 allows the two positioning frames 8 to move relative to each other, which in turn causes the positioning frames 8 to drive the two vertical clamping frames to fix the busbar on the top of the carrier table 6. This further improves the stability of the busbar folding process, thereby avoiding busbar position deviation and improving the quality of the busbar folding process.

[0037] The locking structure includes a lead screw 10 rotatably mounted on a bracket 7. The outer wall of the lead screw 10 is symmetrically threaded with displacement seats 12, which are fixedly installed at the bottom of a positioning frame 8. A fixing frame 25 is fixedly installed on the side wall of the bracket 7 near the positioning frame 8. Bearings are embedded in the inner walls of both sides of the fixing frame 25. The two ends of the lead screw 10 are respectively embedded inside the two bearings. The two displacement seats 12 are threadedly connected to the lead screw 10 through threaded through-holes penetrating the inner cavity. Two sets of opposite threads with the same pitch are formed on the outer wall of the lead screw 10, extending from the center outwards. A first motor 26 is fixed to one side of the fixing frame 25 via a cover. The first motor 26 is electrically connected to an external power source via wires. The output shaft of the first motor 26 passes through the side wall of the fixing frame 25 and is fixedly connected to the corresponding end of the lead screw 10.

[0038] When clamping and fixing the two sides of the busbar, the first motor 26 is connected to the power supply, so that the output shaft of the first motor 26 drives the lead screw 10 to rotate, so that the two displacement seats 12 on the outer wall of the lead screw 10 respectively drive the two positioning frames 8 to move relative to each other, thereby fixing the busbar. The distance between the two positioning frames 8 can be adjusted according to the specifications of the busbar, so that it can be applied to the processing of busbars of different specifications.

[0039] The bracket 7 is provided with a guide rod 11 parallel to the lead screw 10, and the displacement seat 12 is sleeved on the outside of the guide rod 11. The two ends of the guide rod 11 are respectively vertically fixed on the inner walls of the two sides of the fixed frame 12, and the displacement seat 12 slides against the outer wall of the guide rod 11.

[0040] During the process of adjusting the distance between the two displacement seats 12 by rotating the lead screw 10, the displacement seats 12 slide against the outer wall of the guide rod 11 at the same time, thereby ensuring the stability of the movement direction of the displacement seats 12, avoiding positional deviation, and thus ensuring the stability of the busbar folding process.

[0041] It is worth noting that the rotary drive component includes teeth 14 evenly arranged circumferentially on the bottom of the outer wall of the forming turntable 3, and an annular limiting cover 15 fixed to the top of the processing table 1 is fitted onto the bottom of the forming turntable 3. The annular limiting cover 15 is fitted onto the outside of the forming turntable 3 and fits against the top of the teeth 14. The turntable is fixedly installed on the bottom of the forming turntable 3. The teeth 14 are evenly arranged circumferentially on the outer wall of the turntable, so that the turntable drives the teeth 14 to rotate between the annular limiting cover 15 and the processing table 1.

[0042] A connecting groove 29 is formed on the circumferential outer wall of the annular limiting cover 15. A drive gear 13 is rotatably mounted on the outer wall of the processing table 1, and the drive gear 13 passes through the connecting groove 29 and meshes with the teeth 14. The second motor 20 is fixed on the outer wall of the processing table 1, below the connecting groove 29, by a machine cover. The drive gear 13 is fixedly sleeved on the outer wall of the output shaft of the second motor 20 through a central mounting hole. The second motor 20 is electrically connected to an external power source via wires.

[0043] When processing the busbar coiling, the second motor 20 is connected to the power supply, so that the output shaft of the second motor 20 drives the drive gear 13 to rotate, and the teeth 14 meshing with the drive gear 13 drive the forming turntable 3 to rotate, thereby processing the busbar coiling through the coiling part 4, thus ensuring the efficiency of the busbar coiling process.

[0044] In addition, the shifting assembly includes a guide frame 18 that is slidably mounted on the bracket 7, a pressing frame 9 that is fixedly mounted on the top of the guide frame 18 near the processing table 1, and a positioning drive assembly that drives the guide frame 18 to move is provided on the bracket 7.

[0045] The guide frame 18 drives the pressure frame 9 to move towards the carrier stage 6 through the positioning and driving components, thereby limiting and fixing the busbar longitudinally and ensuring the stability of the busbar folding process.

[0046] In addition, a T-shaped guide groove 27 is provided on the side wall of the bracket 7, and a T-shaped guide block 19 is fixedly installed on the side wall of the guide frame 18 and is slidably disposed in the inner cavity of the T-shaped guide groove 27.

[0047] The sliding fit between the T-shaped guide block 19 and the T-shaped guide groove 27 ensures the stability of the guide frame 18 during its position movement and avoids position deviation, thereby ensuring the stability of the pressure frame 9 in limiting the busbar.

[0048] The positioning drive assembly includes a rack 17 fixedly mounted on the side wall of the guide frame 18, and a transmission gear 16 rotatably mounted on the side wall of the bracket 7, meshing with the rack 17. The first motor 26, the second motor 20, and the third motor 28 are all forward and reverse adjustable drive motors. The third motor 28 is fixed to the side wall of the bracket 7 by a cover, and the transmission gear 16 is fixedly sleeved onto the outside of the output shaft of the third motor 28 through a centrally located mounting hole. The third motor 28 is electrically connected to an external power source via wires.

[0049] The output shaft of the third motor 28 drives the transmission gear 16 to rotate, which causes the rack 17 meshing with the transmission gear 16 to move the guide frame 18. The guide frame 18 then drives the pressure frame 9 to limit and fix the busbar. The position of the pressure frame 9 can be adjusted according to the specifications of the busbar, so that it can be used to fix busbars of different specifications.

[0050] Furthermore, ball bearings 24 are evenly arranged circumferentially between the fixed column 2 and the forming turntable 3. Movable grooves 23 are sequentially formed circumferentially on the outer wall of the fixed column 2 near its top, and a sliding groove 22 is formed around the entire inner wall of the central through hole of the forming turntable 3 near its top. Ball bearings 24 are movably embedded within the multiple movable cavities formed by each movable groove 23 and sliding groove 22.

[0051] The circumferential ball bearings 24 ensure the stability of the forming turntable 3 during rotation, thereby guaranteeing the quality of the busbar folding process.

[0052] This embodiment describes a processing and forming device for electrical busbar coils. The working principle is as follows: First, the busbar to be coiled is placed on the carrier platform 6. Then, the busbar slides on the carrier platform 6, allowing it to pass between the two columns of the coil-limiting clamp 5. Next, the first motor 26 is connected to a power source, causing the output shaft of the first motor 26 to drive the lead screw 10 to rotate. This causes the two displacement seats 12 on the outer wall of the lead screw 10 to respectively drive the two positioning frames 8 to move relative to each other, thereby fixing the busbar.

[0053] Then, the output shaft of the third motor 28 drives the transmission gear 16 to rotate, which causes the rack 17 meshing with the transmission gear 16 to move the guide frame 18, so that the guide frame 18 drives the pressure frame 9 to limit and fix the busbar.

[0054] Then, the second motor 20 is connected to the power supply, so that the output shaft of the second motor 20 drives the drive gear 13 to rotate, and the teeth 14 that mesh with the drive gear 13 drive the forming turntable 3 to rotate, thereby processing the busbar by the folding part 4.
