Abstract

This utility model relates to the field of positioning mechanism technology, specifically a positioning mechanism for the hole spacing of a conductive busbar, including a worktable. A punching mechanism is fixedly mounted on the top surface of the worktable via bolts. The advantages of this utility model are: during operation, a first cylinder pushes a U-shaped frame downwards, causing a pressure plate to adhere to the top surface of the conductive busbar. Subsequently, a motor drives a gear to rotate, and through meshing gear plates, the pressure plate slides within the groove of the first positioning plate, thereby pressing the conductive busbar firmly onto the worktable. This top-pressing design can counteract the downward impact force of the drill bit in the punching mechanism, preventing the conductive busbar from warping upwards due to uneven force. The pressure plate is slidably connected to the connecting rod, ensuring a smooth pressing process, while the clearance groove provides space for the gear to move, ensuring smooth transmission. This structure achieves top constraint on the conductive busbar, and together with the side limiting of the first and second positioning plates, forms a three-dimensional positioning, significantly improving the stability during punching and ensuring hole position accuracy.

Description

Technical Field

[0001] This utility model relates to the field of positioning mechanism technology, and in particular to a positioning mechanism for the hole spacing of a conductive strip. Background Technology

[0002] A conductive copper busbar punching machine is a stamping equipment specifically used for processing conductive copper busbars. It can be specifically defined as: a special machine that uses electric or hydraulic drive as a power source to perform plastic processing such as punching, trimming, and bending on conductive copper busbars (strip-shaped conductive components made of high-purity copper) through molds.

[0003] Currently, when punching holes in conductive busbars using a punch press, the common positioning method involves setting two vertical baffles on the worktable. However, this method has significant drawbacks. Existing baffles can only limit the sides of the conductive busbar (i.e., horizontal positioning), but cannot effectively constrain the top of the busbar, causing the busbar to easily warp during punching. This is because the drill bit exerts a downward impact force on the conductive busbar during punching, and without top restraint, the busbar is prone to bending and deforming upwards under this force. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a conductive strip hole spacing positioning mechanism to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a conductive busbar drilling spacing positioning mechanism, including a worktable. A punching mechanism is fixedly mounted on the top surface of the worktable by bolts. A support frame and an electric guide rail are fixedly mounted on the top surface of the worktable by bolts. A movable frame is slidably connected to the top of the electric guide rail. A first positioning plate is fixedly connected to the side of the movable frame near the punching mechanism. A first cylinder is fixedly connected to the top surface of the movable frame. A U-shaped frame is fixedly connected to the output end of the first cylinder. A frame is fixedly mounted to the bottom end of the U-shaped frame by bolts. A pressure plate is slidably connected to the inner wall of the frame. The pressure plate is slidably connected to the first positioning plate. A toothed plate is fixedly connected to the top surface of the pressure plate. A motor is fixedly connected to the side of the U-shaped frame. A gear is fixedly connected to the output end of the motor. The gear meshes with the toothed plate. Two symmetrically arranged second cylinders are fixedly connected to one side of the support frame. A second positioning plate is fixedly connected to the output ends of the two second cylinders.

[0007] Preferably, in any of the above solutions, both the first positioning plate and the second positioning plate are slidably connected to the worktable, and the first positioning plate and the second positioning plate are perpendicular to each other.

[0008] Preferably, in any of the above solutions, the top surface of the first positioning plate is provided with a groove, and the pressure plate is slidably connected to the first positioning plate through the groove.

[0009] Preferably, in any of the above embodiments, a conductive bar is placed on the top surface of the workbench, and the top surface of the conductive bar is in contact with the bottom surface of the pressure plate.

[0010] Preferably, in any of the above solutions, a limiting pin is fixedly installed on one side of the second positioning plate by bolts, and a limiting groove is opened on the top surface of the worktable, through which the limiting pin is slidably connected to the worktable.

[0011] Preferably, in any of the above solutions, the top surface of the frame is provided with a clearance groove, and the gear is slidably connected to the frame through the clearance groove.

[0012] Preferably, in any of the above solutions, the top surface of the U-shaped frame is fixedly connected to two symmetrically arranged limiting posts, and both limiting posts are slidably connected to the movable frame.

[0013] Preferably, in any of the above solutions, the inner wall of the frame is fixedly connected to two symmetrically arranged connecting rods, and the pressure plate is slidably connected to the two connecting rods.

[0014] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0015] 1. The linkage structure between the pressure plate and the gear plate solves the problem of edge warping during punching of the conductive busbar. During operation, the first cylinder pushes the U-shaped frame downwards, causing the pressure plate to fit against the top surface of the conductive busbar. Then, the motor drives the gear to rotate, and through the meshing gear plate, the pressure plate slides within the groove of the first positioning plate, thus pressing the conductive busbar firmly onto the worktable. This top-pressing design counteracts the downward impact force of the drill bit in the punching mechanism, preventing the conductive busbar from warping upwards due to uneven force. The pressure plate and connecting rod are slidably connected, ensuring a smooth pressing process, while the clearance groove provides space for the gear to move, ensuring smooth transmission. This structure achieves top constraint on the conductive busbar, and together with the side limiting of the first and second positioning plates, forms three-dimensional positioning, significantly improving the stability during punching and ensuring hole position accuracy.

[0016] 2. The electric guide rail and dual-cylinder driven positioning plate design enables precise adjustment and rapid positioning of the conductive busbar hole spacing. The electric guide rail drives the moving frame and the first positioning plate to move laterally, accurately adjusting the horizontal distance between the first positioning plate and the punching mechanism to set the hole spacing. The second cylinder pushes the second positioning plate to slide along the limiting groove, achieving positioning along the length of the conductive busbar. The combination of these two systems can meet the hole spacing requirements of conductive busbars of different specifications. For example, when machining equidistant holes, the first positioning plate is moved according to the preset hole spacing via the electric guide rail, eliminating the need for manual measurement and marking, thus reducing errors. The cooperation between the limiting pin and the limiting groove ensures smooth movement of the second positioning plate, while the limiting post guides the sliding of the U-shaped frame, ensuring accurate pressing position of the pressure plate. This design replaces the traditional manual positioning method, improving the efficiency and accuracy of hole spacing positioning, and is suitable for mass production. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0024] like Figures 1 to 5As shown, a conductive busbar punching hole spacing positioning mechanism includes a worktable 1. A punching mechanism 2 is fixedly installed on the top surface of the worktable 1 by bolts. A support frame 3 and an electric guide rail 4 are fixedly installed on the top surface of the worktable 1 by bolts. A movable frame 5 is slidably connected to the top of the electric guide rail 4. A first positioning plate 6 is fixedly connected to the side of the movable frame 5 near the punching mechanism 2. A first cylinder 7 is fixedly connected to the top surface of the movable frame 5. A U-shaped frame 8 is fixedly connected to the output end of the first cylinder 7. A frame 9 is fixedly installed to the bottom end of the U-shaped frame 8 by bolts. A pressure plate 10 is slidably connected to the inner wall of the frame 9. The pressure plate 10 is slidably connected to the first positioning plate 6. A toothed plate 11 is fixedly connected to the top surface of the pressure plate 10. A motor 12 is fixedly connected to the side of the U-shaped frame 8. A gear 13 is fixedly connected to the output end of the motor 12. The gear 13 meshes with the toothed plate 11. Two symmetrically arranged second cylinders 14 are fixedly connected to one side of the support frame 3. A second positioning plate 15 is fixedly connected to the output end of the two second cylinders 14.

[0025] As an optional technical solution of this utility model, both the first positioning plate 6 and the second positioning plate 15 are slidably connected to the worktable 1. The first positioning plate 6 and the second positioning plate 15 are perpendicular to each other, and both are slidably connected to the worktable 1 and perpendicular to each other, which can realize two-dimensional positioning of the conductive busbar 17. The first positioning plate 6 can move laterally under the drive of the electric guide rail 4, and the second positioning plate 15 is driven by the second cylinder 14 to slide longitudinally along the limiting groove 19. The two are set perpendicularly to form a right-angle positioning reference, which can accurately limit the position of the conductive busbar 17 on the worktable 1, ensuring that the conductive busbar can be accurately aligned in both the horizontal and length directions, meeting the positioning requirements of different hole spacings and hole positions, and providing a reliable positioning basis for drilling holes in the conductive busbar.

[0026] As an optional technical solution of this utility model, a groove 16 is provided on the top surface of the first positioning plate 6, and the pressure plate 10 is slidably connected to the first positioning plate 6 through the groove 16. The groove 16 on the top surface of the first positioning plate 6 is slidably connected to the pressure plate 10, so that when the pressure plate 10 presses the conductive busbar 17 from the top, it can slide smoothly along the groove 16, avoiding the pressure plate 10 from shifting or tilting during movement, ensuring that the pressure plate 10 and the top surface of the conductive busbar 17 are evenly attached, thereby effectively suppressing the warping phenomenon of the conductive busbar when punching, and also making the sliding of the pressure plate 10 smoother, improving the operational stability of the device.

[0027] As an optional technical solution of this utility model, a conductive busbar 17 is placed on the top surface of the workbench 1. The top surface of the conductive busbar 17 is in contact with the bottom surface of the pressure plate 10. When the pressure plate 10 is pressed down under the action of the first cylinder 7 and the toothed plate 11, the conductive busbar 17 can be firmly pressed onto the workbench 1, so that the conductive busbar remains stable during the punching process, avoiding the conductive busbar from moving or deforming due to the punching impact force, ensuring the accuracy of the punching position, and at the same time allowing the conductive busbar to better withstand the punching force and improve the punching quality.

[0028] As an optional technical solution of this utility model, a limiting pin 18 is fixedly installed on one side of the second positioning plate 15 by bolts, and a limiting slot 19 is opened on the top surface of the worktable 1. The limiting pin 18 is slidably connected to the worktable 1 through the limiting slot 19. The limiting pin 18 on one side of the second positioning plate 15 is slidably connected to the limiting slot 19 of the worktable 1, which can guide and limit the movement of the second positioning plate 15, ensuring that the second positioning plate 15 slides smoothly along the limiting slot 19 under the drive of the second cylinder 14, avoiding the second positioning plate 15 from shaking or deviating when moving, thereby making the positioning of the second positioning plate 15 more accurate in the length direction of the conductive busbar 17, and improving the positioning accuracy and stability of the entire positioning mechanism.

[0029] As an optional technical solution of this utility model, the top surface of the frame 9 is provided with a clearance groove 20, and the gear 13 is slidably connected to the frame 9 through the clearance groove 20. The limiting pin 18 on one side of the second positioning plate 15 is slidably connected to the limiting groove 19 of the worktable 1, which can guide and limit the movement of the second positioning plate 15, ensuring that the second positioning plate 15 slides smoothly along the limiting groove 19 under the drive of the second cylinder 14, avoiding the second positioning plate 15 from shaking or deviating when moving, thereby making the positioning of the second positioning plate 15 more accurate in the length direction of the conductive busbar 17, and improving the positioning accuracy and stability of the entire positioning mechanism.

[0030] As an optional technical solution of this utility model, the top surface of the U-shaped frame 8 is fixedly connected with two symmetrically arranged limiting posts 21. Both limiting posts 21 are slidably connected to the moving frame 5. The limiting posts 21 on the top surface of the U-shaped frame 8 are slidably connected to the moving frame 5, which can play a guiding role when the U-shaped frame 8 moves up and down, ensuring that the U-shaped frame 8 rises and falls smoothly under the drive of the first cylinder 7, avoiding the U-shaped frame 8 from tilting or shaking, so that the pressure plate 10 can accurately fit or separate from the top surface of the conductive bar 17, thereby improving the operating accuracy and stability of the device.

[0031] As an optional technical solution of this utility model, the inner wall of the frame 9 is fixedly connected with two symmetrically arranged connecting rods 22. The pressure plate 10 is slidably connected to the two connecting rods 22. The connecting rods 22 on the inner wall of the frame 9 are slidably connected to the pressure plate 10, which provides guidance and support for the movement of the pressure plate 10. This ensures that the pressure plate 10 slides smoothly along the connecting rods 22 under the drive of the toothed plate 11, and avoids the pressure plate 10 from deviating or getting stuck during the sliding process. This allows the pressure plate 10 to evenly press the conductive busbar 17, ensuring the pressing effect on the conductive busbar, and also extending the service life of the pressure plate 10.

[0032] A conductive busbar hole spacing positioning mechanism, the working principle of which is as follows:

[0033] 1): During operation, the first cylinder 7 pushes the U-shaped frame 8 down, so that the pressure plate 10 fits against the top surface of the conductive busbar 17. Then, the motor 12 drives the gear 13 to rotate, and through the meshing toothed plate 11, the pressure plate 10 slides in the groove 16 of the first positioning plate 6, thereby pressing the conductive busbar 17 onto the worktable.

[0034] 2): The pressure plate 10 is slidably connected to the connecting rod 22 to ensure a smooth pressing process, while the clearance groove 20 provides space for the gear 13 to move, ensuring smooth transmission.

[0035] 3): The electric guide rail 4 drives the moving frame 5 and the first positioning plate 6 to move laterally, which can precisely adjust the horizontal distance between the first positioning plate 6 and the punching mechanism 2 to set the hole spacing.

[0036] In summary, this conductive busbar punching spacing positioning mechanism solves the problem of edge warping during conductive busbar punching through the linkage structure of the pressure plate and the gear plate. During operation, the first cylinder 7 pushes the U-shaped frame 8 downwards, causing the pressure plate 10 to fit against the top surface of the conductive busbar 17. Then, the motor 12 drives the gear 13 to rotate, which, through the meshing gear plate 11, causes the pressure plate 10 to slide within the groove 16 of the first positioning plate 6, thereby pressing the conductive busbar 17 firmly onto the worktable. This top-pressing design counteracts the downward impact force of the drill bit in the punching mechanism 2, preventing the conductive busbar 17 from warping upwards due to uneven force. The pressure plate 10 is slidably connected to the connecting rod 22, ensuring a smooth pressing process, while the clearance groove 20 provides space for the gear 13 to move, ensuring smooth transmission. This structure achieves top constraint on the conductive busbar, and together with the side limiting of the first positioning plate 6 and the second positioning plate 15, forms a three-dimensional positioning, significantly improving the stability during punching and ensuring hole position accuracy. The electric guide rail and the positioning plate design driven by dual cylinders enable precise adjustment and rapid positioning of the conductive busbar hole spacing. The electric guide rail 4 drives the moving frame 5 and the first positioning plate 6 to move laterally, which can precisely adjust the horizontal distance between the first positioning plate 6 and the punching mechanism 2 to set the hole spacing; the second cylinder 14 pushes the second positioning plate 15 to slide along the limiting groove 19 to achieve positioning of the conductive busbar 17 in the length direction. The combination of the two can meet the hole spacing requirements of conductive busbars of different specifications. For example, when processing equidistant holes, the first positioning plate 6 is moved according to the preset hole spacing by the electric guide rail 4, eliminating the need for manual measurement and marking, and reducing errors. The cooperation between the limiting pin 18 and the limiting groove 19 ensures that the second positioning plate 15 moves smoothly, while the limiting post 21 guides the sliding of the U-shaped frame 8 to ensure that the pressure plate 10 is pressed down accurately. This design replaces the traditional manual positioning method, improving the efficiency and accuracy of hole spacing positioning, and is suitable for mass production.
