Description

Technical Field

[0001] This utility model relates to the field of terminal bending technology, specifically to a combined power terminal bending fixture. Background Technology

[0002] Terminals are components that connect a battery to an external conductor. In electrical engineering, terminals often refer to wiring terminals, also called wire terminals. Types include single-hole, double-hole, plug-in, and hook types. Materials include silver-plated copper, zinc-plated copper, copper, aluminum, and iron. Their primary function is to transmit electrical signals or conduct electricity. During terminal manufacturing, bending fixtures are typically used to bend and adjust the terminals to meet different production needs. Modular terminals (such as terminal blocks) consist of multiple terminals and usually include a fixing device (such as a rail-mounted frame). They can connect multiple wires simultaneously and support marking and quick plugging / unplugging.

[0003] A search revealed that a terminal bending processing fixture was published in China on April 2, 2024, with patent publication number CN220710823U. The fixture is generally described as follows: a fixture body is included, a first U-shaped moving plate is mounted on the top of the fixture body via a first moving mechanism, a U-shaped rotating plate is mounted on one side of the first U-shaped moving plate via a rotating mechanism, a bending column is fixedly mounted on the inner wall of the U-shaped rotating plate, a bending slot is provided on the front of the bending column, and a second U-shaped moving plate is mounted on one side of the fixture body via a second moving mechanism.

[0004] While the aforementioned existing technical solution facilitates bending of the terminals, the bent portion of the device is not easily removed from the bending slot, making it difficult to remove the terminals after bending, thus reducing work efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a combined power terminal bending fixture to solve the problem mentioned in the background technology that it is inconvenient to remove the terminal after bending, thus reducing work efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a combined power terminal bending fixture, comprising a worktable and a connecting frame. A support block is fixedly connected to the top of the worktable, and a translation groove is fixedly connected to the top of the support block. A first threaded rod is rotatably connected inside the translation groove, and a mounting frame is threaded onto the first threaded rod. Two discs are rotatably connected to the inner side wall of the mounting frame. The connecting frame is fixedly connected between the two discs. An electric push rod is mounted on the connecting frame, and a U-shaped frame is fixedly connected to one end of the electric push rod. Multiple bending columns of different specifications are provided on the inner side wall of the U-shaped frame. A bending column of different specifications is mounted on the outer wall of the translation groove. The worktable is equipped with a first motor connected to a first threaded rod. A second motor connected to a disc is mounted on the outer wall of the mounting frame. A control slot is provided at the top of the worktable. A second threaded rod is rotatably connected inside the control slot. A threaded component is threaded onto the second threaded rod. A C-shaped frame is fixedly connected to the top of the threaded component. A bidirectional threaded rod is rotatably connected inside the C-shaped frame. Two connecting plates are threaded onto the bidirectional threaded rod. Each connecting plate has a clamping plate at one end that is close to the other. A third motor connected to the bidirectional threaded rod is mounted at the top of the C-shaped frame. A fourth motor connected to the second threaded rod is mounted at one end of the worktable.

[0009] By adopting the above technical solution, the terminal is placed between two clamping plates. A third motor is started to drive a bidirectional threaded rod to rotate, which in turn moves two connecting plates, causing the two clamping plates to engage and clamp the terminal in a centered position, aligning it with the bending post. A first motor is then started to drive a first threaded rod to rotate, which in turn moves the mounting frame, adjusting the position of the bending post to align it with the terminal. A fourth motor is then started to drive a second threaded rod to rotate, which in turn moves the threaded component and the C-shaped frame, allowing the portion of the terminal to be bent to be inserted into the bending post. A second motor is then started to drive a disc to rotate, which in turn rotates the connecting frame, the U-shaped frame, and the bending post, causing the bending post to bend the terminal. After bending, an electric push rod is started to move the U-shaped frame, which in turn moves the bending post away from the terminal. Finally, a fourth motor is started to drive the second threaded rod to rotate in the opposite direction, causing the C-shaped frame to retract the terminal. This facilitates the removal of the bent terminal, improving work efficiency.

[0010] Optionally, each of the two connecting plates is fixedly connected to a matching bending pressure plate at its left end, with the left end of the bending pressure plate corresponding to the central axis of the disc.

[0011] By adopting the above technical solution, when the disc bends and rotates the terminal, the bending point of the terminal is at the central axis of the disc. The two bending pressure plates cooperate to clamp the part of the terminal that needs to be bent. When the C-shaped frame moves to the leftmost end, one end of the bending pressure plate coincides with the central axis of the disc, which facilitates the equipment to bend the terminal accurately.

[0012] Optionally, the inner wall of the C-shaped frame is provided with two limiting slide rods, both of which are slidably connected to the two connecting plates.

[0013] By adopting the above technical solution, the limiting slide bar is used to limit the connection plate, prevent the connection plate from shaking, and improve the clamping stability of the terminal by the equipment.

[0014] Optionally, both clamping plates are fixedly connected with anti-slip pads at their adjacent ends.

[0015] By adopting the above technical solution, the anti-slip pad is used to increase the friction between the terminal and the clamping plate, reduce the probability of the terminal slipping off, and thus improve the stability of the terminal.

[0016] Optionally, the mounting frame is fixedly connected with multiple connectors that are respectively aligned with the positions of multiple bending columns. Each connector is equipped with a first sensor. The top of the translation groove is equipped with a second sensor that cooperates with the multiple first sensors. The second sensor is electrically connected to the first motor.

[0017] By adopting the above technical solution, when adjusting the position of the bending column, different first sensors and second sensors are aligned, corresponding to different bending columns and terminals being aligned, which makes it easier to adjust different bending columns to be aligned with the terminals, thereby achieving the purpose of facilitating the adjustment of the bending columns.

[0018] Optionally, two matching limiting grooves are provided on the inner side wall of the connecting frame, and two limiting blocks that are slidably connected to the limiting grooves are fixedly connected to the outer wall of the U-shaped frame.

[0019] By adopting the above technical solution, the limiting groove and the limiting block cooperate to limit the U-shaped frame, prevent the U-shaped frame from shaking or tilting, and prevent one end of the bending column from moving to the central axis of the disc, thereby improving the stability of the equipment.

[0020] (III) Beneficial Effects

[0021] In summary, this utility model has at least one of the following beneficial technical effects:

[0022] This combined power terminal bending fixture places the terminal between two clamping plates. A third motor rotates a bidirectional threaded rod, which in turn moves two connecting plates, causing the clamping plates to engage and centrally clamp the terminal, aligning it with the bending post. A first motor then rotates a first threaded rod, which moves a mounting frame to adjust the bending post's position, ensuring it aligns with the terminal. A fourth motor then rotates a second threaded rod, which moves a threaded component and a C-shaped bracket, inserting the portion of the terminal to be bent into the bending post. A second motor then rotates a disc, which in turn rotates a connecting frame, a U-shaped bracket, and the bending post, bending the terminal. After bending, an electric push rod moves the U-shaped bracket, which in turn moves the bending post away from the terminal. Finally, the fourth motor rotates the second threaded rod in the opposite direction, causing the C-shaped bracket to retract the terminal, facilitating removal after bending and improving work efficiency.

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 present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 1-4A combined power terminal bending fixture includes a worktable 1 and a connecting frame 2. A support block 3 is fixedly connected to the top of the worktable 1, and a translation groove 4 is fixedly connected to the top of the support block 3. A first threaded rod 5 is rotatably connected inside the translation groove 4. A mounting frame 6 is threadedly connected to the first threaded rod 5. Two discs 7 are rotatably connected to the inner side wall of the mounting frame 6. The connecting frame 2 is fixedly connected between the two discs 7. An electric push rod 8 is mounted on the connecting frame 2. A U-shaped frame 9 is fixedly connected to one end of the electric push rod 8. Multiple bending columns 10 of different specifications are provided on the inner side wall of the U-shaped frame 9. A bending column connected to the first threaded rod 5 is mounted on the outer wall of the translation groove 4. A first motor 11 is connected to the mounting frame 6. A second motor 12, connected to the disc 7, is mounted on the outer wall of the mounting frame 6. A control slot is provided at the top of the worktable 1. A second threaded rod 13 is rotatably connected inside the control slot. A threaded component is threaded onto the second threaded rod 13. A C-shaped frame 14 is fixedly connected to the top of the threaded component. A bidirectional threaded rod 15 is rotatably connected inside the C-shaped frame 14. Two connecting plates 16 are threaded onto the bidirectional threaded rod 15. Each connecting plate 16 has a clamping plate 17 at one end that is close to the other. A third motor 18, connected to the bidirectional threaded rod 15, is mounted at the top of the C-shaped frame 14. A third motor 18, connected to the bidirectional threaded rod 15, is mounted at one end of the worktable 1. The fourth motor 19, connected to the threaded rod 13, places the terminal between the two clamping plates 17. The third motor 18 is then activated, driving the bidirectional threaded rod 15 to rotate. The bidirectional threaded rod 15 moves the two connecting plates 16, thereby causing the two clamping plates 17 to engage and centrally clamp and fix the terminal, aligning it with the bending post 10. The first motor 11 is then activated, driving the first threaded rod 5 to rotate. The first threaded rod 5 moves the mounting frame 6, adjusting the position of the bending post 10 so that it aligns with the terminal. At this point, the fourth motor 19 is activated, driving the second threaded rod 13 to rotate. The second threaded rod 13... The moving threaded part and C-shaped bracket 14 move so that the part of the terminal that needs to be bent is inserted into the bending column 10. At this time, the second motor 12 is started to drive the disc 7 to rotate. The disc 7 drives the connecting bracket 2, U-shaped bracket 9 and bending column 10 to rotate, so that the bending column 10 bends the terminal. After bending is completed, the electric push rod 8 is started to drive the U-shaped bracket 9 to move. The U-shaped bracket 9 drives the bending column 10 to move away from the terminal. At this time, the fourth motor 19 is started to drive the second threaded rod 13 to rotate in the opposite direction, so that the C-shaped bracket 14 drives the terminal to retract. This makes it easier to remove the terminal after bending, thereby improving work efficiency.

[0032] Reference Figure 1 and Figure 2Both connecting plates 16 have a matching bending pressure plate 20 fixedly connected to their left ends. The left end of the bending pressure plate 20 corresponds to the central axis of the disc 7. When the disc 7 bends and rotates the terminal, the bending point of the terminal is at the central axis of the disc 7. The two bending pressure plates 20 cooperate to clamp the part of the terminal that needs to be bent. When the C-shaped frame 14 moves to the leftmost end, one end of the bending pressure plate 20 coincides with the central axis of the disc 7, which facilitates the equipment to bend the terminal accurately.

[0033] Reference Figures 1-4 The inner wall of the C-shaped frame 14 is provided with two limiting slide rods 21. Both limiting slide rods 21 are slidably connected to the two connecting plates 16. The limiting slide rods 21 are used to limit the connecting plates 16 to prevent the connecting plates 16 from shaking and improve the clamping stability of the equipment for the terminals.

[0034] Reference Figure 1 and Figure 2 Both clamping plates 17 have anti-slip pads 22 fixedly connected to their respective ends that are close to each other. The anti-slip pads 22 are used to increase the friction between the terminal and the clamping plate 17, reduce the probability of the terminal slipping off, and thus improve the stability of the terminal.

[0035] Reference Figure 1 and Figure 3 Multiple connectors 23 are fixedly connected to the mounting frame 6, each aligned with the position of a multiple bending column 10. Each connector 23 is equipped with a first sensor 24. A second sensor 25, which cooperates with the multiple first sensors 24, is installed at the top of the translation groove 4. The second sensor 25 is electrically connected to the first motor 11. When adjusting the position of the bending column 10, different first sensors 24 and second sensors 25 are aligned, corresponding to different bending columns 10 being aligned with the terminals. This facilitates the adjustment of different bending columns 10 to be aligned with the terminals, thereby achieving the purpose of facilitating the adjustment of the bending columns 10.

[0036] Reference Figure 4 and Figure 5 The inner wall of the connecting frame 2 has two matching limiting grooves 26, and the outer wall of the U-shaped frame 9 has two limiting blocks 27 that are slidably connected to the limiting grooves. The limiting grooves 26 and the limiting blocks 27 are matched to limit the U-shaped frame 9, prevent the U-shaped frame 9 from shaking or tilting, and prevent one end of the bending column 10 from moving to the central axis of the disc 7, thereby improving the stability of the equipment.

[0037] It should be further explained that the electric actuator, first motor, second motor, third motor, fourth motor, first sensor, and second sensor in this embodiment are conventional devices known to those skilled in the art and available on the market. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. They will not be described in detail here. The electric actuator, first motor, second motor, third motor, fourth motor, first sensor, and second sensor are equipped with matching control switches. The installation position of the control switches can be selected according to actual usage requirements to facilitate operation and control by the operator.

[0038] In summary, the working principle and process of this combined power terminal bending fixture are as follows: First, the terminal is placed between the two clamping plates 17. Then, the third motor 18 is started, driving the bidirectional threaded rod 15 to rotate. The bidirectional threaded rod 15 moves the two connecting plates 16, thereby causing the two clamping plates 17 to engage and clamp the terminal in a centered position, aligning the terminal with the bending column 10. Next, the first motor 11 is started, driving the first threaded rod 5 to rotate. The first threaded rod 5 moves the mounting frame 6, adjusting the position of the bending column 10 so that it aligns with the terminal corresponding to its specifications. Finally, the fourth motor is started. Motor 19 drives the second threaded rod 13 to rotate, which in turn moves the threaded component and C-shaped bracket 14, allowing the portion of the terminal to be bent to be inserted into the bending column 10. At this point, the second motor 12 is activated, driving the disc 7 to rotate. The disc 7 then drives the connecting bracket 2, U-shaped bracket 9, and bending column 10 to rotate, causing the bending column 10 to bend the terminal. After bending is complete, the electric push rod 8 is activated, moving the U-shaped bracket 9, which in turn moves the bending column 10 away from the terminal. Then, the fourth motor 19 is activated, driving the second threaded rod 13 to rotate in the opposite direction, causing the C-shaped bracket 14 to retract the terminal, facilitating end alignment. After bending, the terminal is removed to improve work efficiency. When the disc 7 bends and rotates, the bending point of the terminal is at the central axis of the disc 7. The two bending pressure plates 20 cooperate to clamp the part of the terminal that needs to be bent. When the C-shaped frame 14 moves to the leftmost end, one end of the bending pressure plate 20 coincides with the central axis of the disc 7, which facilitates the precise bending of the terminal by the equipment. The limiting slide rod 21 is used to limit the connecting plate 16 to prevent the connecting plate 16 from shaking and improve the clamping stability of the terminal by the equipment. The anti-slip pad 22 is used to increase the friction between the terminal and the clamping plate 17 and reduce the friction. The probability of terminal slippage is reduced, thereby improving terminal stability. When adjusting the position of the bending column 10, different first sensors 24 and second sensors 25 are aligned, corresponding to different bending columns 10 and terminals. This facilitates the adjustment of different bending columns 10 to be aligned with the terminals, thus making it easier to adjust the bending column 10. The limiting groove 26 and the limiting block 27 cooperate to limit the U-shaped frame 9, preventing the U-shaped frame 9 from shaking or tilting, and preventing one end of the bending column 10 from moving to the central axis position of the disk 7, thereby improving equipment stability.

[0039] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
