Description

Technical Field

[0001] The present invention belongs to the technical field of automotive interior processing, and specifically relates to a punching device for automotive interior processing that can quickly position. Background Art

[0002] With the rapid development of the automotive industry and the continuous improvement of consumers' requirements for the quality of automotive interiors, the processing accuracy and efficiency of automotive interior parts have become the focus of the industry's attention. Automotive interior parts (such as seat covers, instrument panel panels, door trim parts, air-conditioning outlet grilles, etc.) usually need to be precisely punched to meet requirements such as ventilation, installation, aesthetics, or function integration; After retrieval, for example, in the patent: CN219926260U, a punching device for automotive interior PVC composite materials, which includes a workbench. Two fixing mechanisms are installed on the top surface of the workbench, and a support mechanism is connected to the bottom surface of the workbench. The support mechanism includes a fixing frame, which is fixed to the workbench. A first threaded screw is rotatably connected to the inner wall of the fixing frame. A first motor is connected to the side of the fixing frame, and one end of the output shaft of the first motor is connected to the first threaded screw. A moving block is threadedly connected to the circumferential side of the first threaded screw. The bottom surface of the moving block is slidably matched with the fixing frame, and a support plate is connected to the top surface of the moving block. The punching device for automotive interior PVC composite materials of this utility model solves the problem that when the punching drill of the existing punching device punches, the downward pressure of the drill on the plate often causes the area around the drill hole to be sunken and deformed, thus affecting the overall quality of the plate and resulting in poor punching quality; During the working process of the existing punching device, it is necessary to first place the automotive interior material below the punching structure and adjust its position. Due to the lack of a positioning function, whenever a workpiece is replaced, it is necessary to re-align and position, resulting in a long time consumption and being difficult to meet the actual needs of large-scale production of automotive interior parts. Summary of the Invention

[0003] The purpose of the present invention is to provide a punching device for automotive interior processing that can quickly position, so as to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A punching device for automotive interior processing that can quickly position, which includes a workbench. A support plate is fixedly installed at the top end of the workbench, a cylinder is installed at the top end of the support plate, the output end of the cylinder is connected to a punching structure, and a positioning component is arranged below the punching structure; The positioning component includes a first positioning plate and a second positioning plate arranged below the punching structure. The first positioning plate and the second positioning plate are distributed in an L shape, and both the first positioning plate and the second positioning plate are installed at the top end of the workbench.

[0005] During operation, place the automotive interior material to be punched at the top of the workbench. By forming an L-shape with the first positioning plate and the second positioning plate and using the right-angle side as the reference surface, make the edge of the material fit against the side walls of the first positioning plate and the second positioning plate to achieve rapid positioning. There is no need for repeated measurement or adjustment, which can meet the actual needs of large-scale production of automotive interior parts and improve processing efficiency.

[0006] As a further technical solution of the present invention, a connecting plate is provided on one side of the second positioning plate, and two moving seats are installed on the outer wall of the connecting plate. Both of the two moving seats are slidably installed on the inner wall of the workbench. A reciprocating screw rod is threadedly connected to the inner wall of one of the moving seats, and a motor is installed at one end of the reciprocating screw rod.

[0007] After punching, start the motor to drive the reciprocating screw rod to rotate. The rotation of the reciprocating screw rod drives the movement of the moving seat, the movement of the moving seat drives the movement of the connecting plate, and when the connecting plate moves, it drives the second positioning plate to move outwards to push away the punched material. There is no need for workers to manually remove the punched material, which can further improve processing efficiency.

[0008] As a further technical solution of the present invention, a first threaded rod is rotatably installed on one side of the first positioning plate, and a fixing plate is threadedly connected to the outer wall of the first threaded rod. The fixing plate is fixedly installed on the top of the workbench.

[0009] During operation, rotate the first threaded rod to drive the first positioning plate to move towards or away from the fixing plate, changing the distance between the first positioning plate and the punching structure, thereby adjusting the positioning distance, which can meet the production requirements of various types of automotive interior parts and improve the adaptability of the device.

[0010] As a further technical solution of the present invention, a slider is fixedly connected to the top of the moving seat, and the slider is slidably installed on the top of the connecting plate.

[0011] As a further technical solution of the present invention, a second threaded rod is threadedly connected to the inner wall of the top of the second positioning plate, and the second threaded rod is rotatably installed on the side wall of the connecting plate.

[0012] During operation, rotate the second threaded rod to drive the second positioning plate to move towards or away from the connecting plate, changing the distance between the second positioning plate and the punching structure, thereby adjusting the positioning distance, which can meet the production requirements of various types of automotive interior parts and further improve the adaptability of the device.

[0013] As a further technical solution of the present invention, a limiting block is fixedly connected to one end of the second positioning plate, and the limiting block is slidably installed on the inner wall of the chute. The chute is opened on the inner wall of the first positioning plate.

[0014] When the positioning plate 1 adjusts the positioning distance, the limiting block is limited through the sliding groove to drive the movement of the positioning plate 2, so as to ensure that the positioning plate 1 is still L-shaped with the positioning plate 2 after adjusting the positioning distance, ensuring the positioning effect.

[0015] As a further technical solution of the present invention, a collection box is provided on one side of the workbench. A chamber 1 and a chamber 2 are opened inside the collection box, and a filter plate is provided at the top of the chamber 1.

[0016] When the positioning plate 2 moves to push the material, the material that has been punched is pushed to the top of the collection box. The waste of punching enters the chamber 1 through the filter plate for collection, and the finished product enters the chamber 2 for collection, for classified storage, which helps to improve the product quality and consistency.

[0017] As a further technical solution of the present invention, one end of the reciprocating lead screw is fixedly connected with a first bevel gear. A second bevel gear is meshed on one side of the first bevel gear. A rotating shaft is fixedly installed on the inner wall of the second bevel gear. A cam is fixedly installed on the outer wall of the rotating shaft. An installation plate is provided at the top of the cam. Convex blocks are evenly installed at the top end of the installation plate. The installation plate is slidably installed inside the workbench, and a second spring is provided between the installation plate and the workbench.

[0018] When the positioning plate 2 moves to push the material, the rotation of the reciprocating lead screw drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the cam. When the convex end of the cam rotates to the upper side to drive the installation plate to move upward, the movement of the installation plate drives the convex blocks to move upward and slide out of the workbench to knock the bottom of the material, preventing the chips generated by punching from possibly adhering to the holes or the bottom of the material. The knocking can make the chips fall off through vibration, avoiding blocking the holes or affecting the function.

[0019] As a further technical solution of the present invention, the cam is arranged on one side of the filter plate. The filter plate is slidably installed inside the collection box, and first springs are evenly arranged between the filter plate and the collection box.

[0020] The beneficial effects of the present invention are as follows: Through the setting of the positioning component of the present invention, during work, the automotive interior material to be punched is placed on the top of the workbench. By using the L shape formed by the positioning plate 1 and the positioning plate 2 and using the right-angle side as the reference surface, the edge of the material is made to fit the side walls of the positioning plate 1 and the positioning plate 2 to achieve rapid positioning, without repeated measurement or adjustment, which can meet the actual needs of large-scale production of automotive interior parts and improve the processing efficiency.

[0021] In the present invention, through the arrangement of pushing the material outwards by the second positioning plate, after punching, the motor is started to drive the reciprocating lead screw to rotate. The rotation of the reciprocating lead screw drives the movement of the moving seat, and the movement of the moving seat drives the movement of the connecting plate. When the connecting plate moves, it drives the second positioning plate to move outwards to push away the punched material, eliminating the need for manual removal of the punched material by the staff and further improving the processing efficiency.

[0022] In the present invention, when discharging the material, the bottom of the material is struck by the convex block. When the second positioning plate moves to push the material, the rotation of the reciprocating lead screw drives the rotation of the first bevel gear, the rotation of the first bevel gear drives the rotation of the second bevel gear, and the rotation of the second bevel gear drives the rotation of the cam. When the convex end of the cam rotates to the upper side, it drives the mounting plate to move upwards. The movement of the mounting plate drives the convex block to move upwards and slide out of the workbench to strike the bottom of the material, preventing the debris generated by punching from possibly adhering to the inside of the hole or the bottom of the material. The striking can cause the debris to fall off through vibration, avoiding blockage of the hole or affecting the function. BRIEF DESCRIPTION OF THE DRAWINGS

A positioning component is arranged below the punching structure 28; The positioning component includes a first positioning plate 4 and a second positioning plate 5 arranged below the punching structure 28. The first positioning plate 4 and the second positioning plate 5 are distributed in an L shape. Both the first positioning plate 4 and the second positioning plate 5 are installed at the top of the workbench 1.

[0027] Existing: CN219926260U discloses a punching device for automotive interior PVC composite materials. The workbench 1 and the punching structure 28 proposed in this application document are disclosed in this patent. These technical means will not be elaborated one by one here; Through the setting of the positioning component, during work, the automotive interior decoration material to be punched is placed at the top of the workbench 1. By using the L shape formed by the first positioning plate 4 and the second positioning plate 5 and using the right-angle side as the reference surface, the edge of the material is made to fit against the side walls of the first positioning plate 4 and the second positioning plate 5 to achieve quick positioning, without the need for repeated measurement or adjustment, which can meet the actual needs of large-scale production of automotive interior parts and improve the processing efficiency.

[0028] As Figure 2 、 Figure 3 and Figure 7 shown, a connecting plate 8 is arranged on one side of the second positioning plate 5. Two moving seats 9 are installed on the outer wall of the connecting plate 8. Both of the two moving seats 9 are slidably installed on the inner wall of the workbench 1. A reciprocating lead screw 11 is threadedly connected to the inner wall of one of the moving seats 9. One end of the reciprocating lead screw 11 is installed with a motor 12.

[0029] Through the setting of pushing the material by moving the second positioning plate 5 outwards, after punching, the motor 12 is started to drive the reciprocating lead screw 11 to rotate. The rotation of the reciprocating lead screw 11 drives the movement of the moving seat 9. The movement of the moving seat 9 drives the movement of the connecting plate 8. When the connecting plate 8 moves, it drives the second positioning plate 5 to move outwards to push away the punched material, without the need for workers to manually remove the punched material, which can further improve the processing efficiency.

[0030] As Figure 1 、 Figure 2 、 Figure 4 andFigure 7 As shown, a first threaded rod 6 is rotatably installed on one side of the positioning plate 1-4, and an outer wall of the first threaded rod 6 is threadedly connected with a fixing plate 7. The fixing plate 7 is fixedly installed at the top end of the workbench 1.

[0031] During operation, by rotating the first threaded rod 6, the positioning plate 1-4 is driven to move towards or away from one side of the fixing plate 7, changing the distance between the positioning plate 1-4 and the punching structure 28, thereby adjusting the positioning distance, which can meet the production requirements of various automotive interior parts and improve the adaptability of the device.

[0032] As Figure 2 and Figure 3 shown, a slider 10 is fixedly connected to the top end of the moving seat 9, and the slider 10 is slidably installed on the top of the connecting plate 8.

[0033] When adjusting the position of the positioning plate 1-4, the movement of the positioning plate 1-4 drives the connecting plate 8 to slide on the outer wall of the slider 10, and through their connection, after the positioning plate 1-4 adjusts its position, it can still drive the positioning plate 2-5 to move and push materials through the connecting plate 8.

[0034] As Figure 1 and Figure 7 shown, a second threaded rod 15 is threadedly connected to the inner wall of the top of the positioning plate 2-5, and the second threaded rod 15 is rotatably installed on the side wall of the connecting plate 8.

[0035] During operation, by rotating the second threaded rod 15, the positioning plate 2-5 is driven to move towards or away from one side of the connecting plate 8, changing the distance between the positioning plate 2-5 and the punching structure 28, thereby adjusting the positioning distance, which can meet the production requirements of various automotive interior parts and further improve the adaptability of the device.

[0036] As Figure 7 shown, a limiting block 13 is fixedly connected to one end of the positioning plate 2-5, and the limiting block 13 is slidably installed on the inner wall of the sliding groove 14, and the sliding groove 14 is opened on the inner wall of the positioning plate 1-4.

[0037] The cross-section of the limiting block 13 is T-shaped; When the positioning plate 2-5 moves to push materials, the movement of the positioning plate 2-5 drives the limiting block 13 to slide in the inner wall of the sliding groove 14; When the positioning plate 1-4 adjusts the positioning distance, the limiting block 13 is limited by the sliding groove 14 to drive the positioning plate 2-5 to move, so as to ensure that the positioning plate 1-4 and the positioning plate 2-5 are still L-shaped after adjusting the positioning distance, ensuring the positioning effect.

[0038] As Figure 1 , Figure 2 and Figure 4As shown in the figure, a collection box 16 is provided on one side of the workbench 1. A first chamber 17 and a second chamber 18 are provided inside the collection box 16. A filter plate 19 is provided at the top of the first chamber 17.

[0039] When the second positioning plate 5 moves to push the material, the material that has been punched is pushed to the top of the collection box 16. The waste from punching enters the first chamber 17 through the filter plate 19 for collection, and the finished products enter the second chamber 18 for collection, for classified storage, which helps to improve product quality and consistency.

[0040] As Figure 7 shown, one end of the reciprocating lead screw 11 is fixedly connected to a first bevel gear 20. A second bevel gear 21 is meshed on one side of the first bevel gear 20. A rotating shaft 22 is fixedly installed on the inner wall of the second bevel gear 21. A cam 23 is fixedly installed on the outer wall of the rotating shaft 22. An installation plate 25 is provided at the top of the cam 23. Protrusions 26 are evenly installed at the top of the installation plate 25. The installation plate 25 is slidably installed inside the workbench 1. A second spring 27 is provided between the installation plate 25 and the workbench 1.

[0041] When the material is discharged, the bottom of the material is struck by the protrusions 26. When the second positioning plate 5 moves to push the material, the rotation of the reciprocating lead screw 11 drives the rotation of the first bevel gear 20. The rotation of the first bevel gear 20 drives the rotation of the second bevel gear 21. The rotation of the second bevel gear 21 drives the rotation of the cam 23. When the convex end of the cam 23 rotates to the upper side, it drives the installation plate 25 to move upward. The movement of the installation plate 25 drives the protrusions 26 to move upward and slide out of the workbench 1 to strike the bottom of the material, preventing the debris generated by punching from possibly adhering to the holes or the bottom of the material. The striking can make the debris fall off through vibration, avoiding blocking the holes or affecting the function.

[0042] As Figure 4 and Figure 5 shown, the cam 23 is provided on one side of the filter plate 19. The filter plate 19 is slidably installed inside the collection box 16. First springs 24 are evenly provided between the filter plate 19 and the collection box 16.

[0043] When the convex end of the cam 23 rotates to one side of the filter plate 19, it drives the filter plate 19 to slide towards the inner wall of the collection box 16, and the filter plate 19 is reset by the elastic potential energy of the first springs 24, causing the filter plate 19 to vibrate, facilitating the separation of the material and the waste, and helping to improve product quality.

[0044] Working principle and usage process: During operation, first adjust the positioning points according to requirements. By rotating the first threaded rod 6, drive the first positioning plate 4 to move towards or away from the fixed plate 7, changing the distance between the first positioning plate 4 and the punching structure 28. By rotating the second threaded rod 15, drive the second positioning plate 5 to move towards or away from the connecting plate 8, changing the distance between the second positioning plate 5 and the punching structure 28. Then, place the automotive interior material to be punched on the top of the workbench 1. Through the L-shape formed by the first positioning plate 4 and the second positioning plate 5 and using the right-angle side as the reference surface, make the edge of the material fit against the side walls of the first positioning plate 4 and the second positioning plate 5 to achieve rapid positioning. Then, drive the punching structure 28 to move downward by the cylinder 3 to punch the material. After punching, start the motor 12 to drive the reciprocating lead screw 11 to rotate. The rotation of the reciprocating lead screw 11 drives the movement of the moving seat 9. The movement of the moving seat 9 drives the movement of the connecting plate 8. When the connecting plate 8 moves, it drives the second positioning plate 5 to move outward to push the punched material away. The already punched material is pushed to the top of the collection box 16. The punching waste enters the first chamber 17 through the filter plate 19 for collection, and the finished products enter the second chamber 18 for collection and are classified and stored. At the same time, the rotation of the reciprocating lead screw 11 drives the rotation of the first bevel gear 20. The rotation of the first bevel gear 20 drives the rotation of the second bevel gear 21. The rotation of the second bevel gear 21 drives the rotation of the cam 23. When the convex end of the cam 23 rotates to the upper side, it drives the mounting plate 25 to move upward. The movement of the mounting plate 25 drives the convex block 26 to move upward and slide out of the workbench 1 to strike the bottom of the material to assist in separating the waste. When the convex end of the cam 23 rotates to one side of the filter plate 19, it drives the filter plate 19 to slide towards the inner wall of the collection box 16, and the filter plate 19 is reset by the elastic potential energy of the first spring 24, causing the filter plate 19 to vibrate and further assisting in separating the waste. Finally, place new material on the top of the workbench 1 and repeat the above steps for continuous processing operations.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
