Description

Technical Field

[0001] This utility model relates to the field of notebook shell punching technology, specifically to a punching device for processing notebook shells. Background Technology

[0002] Laptops are small, portable personal computers. The current trend is towards smaller size and lighter weight while becoming more powerful, leading to their increasingly widespread use. However, the manufacturing process of laptop casings requires punching equipment to create holes to accommodate various interfaces or connect external devices.

[0003] Existing punching equipment typically requires a clamping mechanism to firmly hold the laptop casing during punching to prevent displacement or deformation due to impact, ensuring accurate punching position. For example, a punching device for processing power bank casings disclosed in patent CN216501815U uses a sliding block, threaded rod, rectangular block, and connecting rod to adjust the position of two clamping mechanisms, thereby achieving the purpose of clamping and fixing aluminum plates of different sizes. However, manual operation and adjustment are required. In the production process, if it is necessary to frequently change workpieces of different sizes for punching, manual adjustment of the clamping mechanism position not only consumes a lot of time and reduces production efficiency, but manual adjustment may also lead to unstable clamping or punching position deviation due to improper operation or inaccurate adjustment.

[0004] Therefore, it is necessary to invent a punching device for processing notebook casings to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a punching device for processing notebook shells, in order to solve the problem that manual operation and adjustment are required in the current technology, which not only consumes a lot of time and reduces production efficiency, but may also lead to unstable clamping or punching position deviation due to improper operation or inaccurate adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a punching device for processing notebook shells, comprising a substrate, a base platform disposed above the front side of the substrate, a worktable disposed above the base platform, mounting plates disposed on the left and right sides of the worktable, a sliding groove being formed inside the mounting plate, a slider being disposed inside the sliding groove, a first inclined wedge transmission rod being disposed at the top of the slider, a second inclined wedge transmission rod being disposed directly above the first inclined wedge transmission rod, a connecting plate being disposed on the side wall of the first inclined wedge transmission rod and extending through to a groove inside the worktable, a through groove being formed inside the connecting plate, and a clamping block being slidably installed inside the through groove.

[0007] Preferably, a vertical plate is provided at the rear side above the substrate. A cylinder is provided on the front wall of the vertical plate. A top plate is provided below the cylinder. The top surface of the top plate is connected to the output end of the cylinder. Through the telescopic movement of the cylinder, the top plate and the punch below it are driven to move up and down.

[0008] Preferably, guide rods penetrate through the left and right sides of the top plate and extend to the top surface of the base. The top plate is slidably connected to the guide rods. The arrangement of the guide rods ensures the stability and accuracy of the top plate during up and down movement.

[0009] Preferably, the slider is designed in a "convex" shape structure. The slider is slidably connected to the chute. The slider and the chute are located on the left and right sides of the workbench. The sliding connection between the slider and the chute enables the slider to move freely within the chute, thereby driving the first wedge transmission rod to adjust its position.

[0010] Preferably, there are 2 first wedge transmission rods and 2 second wedge transmission rods. The two second wedge transmission rods are respectively located on the left and right sides of the bottom surface of the top plate. The two first wedge transmission rods are respectively located on the left and right sides of the base. The first wedge transmission rod and the second wedge transmission rod are both provided with inclined planes. The inclined planes of the two first wedge transmission rods face in opposite directions, and the inclined planes of the two second wedge transmission rods also face in opposite directions. The inclined plane of the second wedge transmission rod is accurately corresponding to the inclined plane of the first wedge transmission rod in position. Through the cooperation of the inclined planes of the first wedge transmission rod and the second wedge transmission rod, an effective clamping mechanism is formed.

[0011] Preferably, a first spring is provided between the slider and the workbench. One end of the first spring is installed on the side wall of the slider, and the other end of the first spring is installed on the side wall of the workbench. The setting of the first spring is used for the reset of the slider.

[0012] Preferably, a second spring is provided inside the through groove. One end of the second spring is installed on the inner wall of the through groove, and the other end of the second spring is installed on the side wall of the clamping block. There are 2 clamping blocks, and the two clamping blocks are located on the left and right sides of the groove of the workbench. The setting of the second spring enables the clamping block to have a certain flexibility and is suitable for notebook casings of different sizes.

[0013] Preferably, a punch is provided directly above the workbench and is located on the bottom surface of the top plate. A leakage hole is opened at the groove of the workbench. The position of the leakage hole corresponds to the position of the punch. The leakage hole extends through to the bottom of the base. A collection box is provided below the leakage hole. The collection box is located above the substrate. The setting of the leakage hole enables the waste material after punching to fall smoothly into the collection box, which is convenient for cleaning and maintenance.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. When the punch is driven by a cylinder to descend and punch the laptop shell, the second wedge transmission rod descends synchronously and contacts the inclined surface of the first wedge transmission rod. This design allows the first wedge transmission rod to slide along the slide groove through the slider, thereby driving the clamping block to approach the laptop shell inside the worktable groove. This transmits force during the punching process and drives the clamping block to clamp the laptop shell, thus achieving workpiece clamping while punching. This collaborative working method not only improves the accuracy of punching but also ensures the stability of the workpiece during the punching process, effectively preventing workpiece movement or deformation.

[0016] 2. The clamping block and the connecting plate of this utility model are connected by a second spring. The elastic design of the second spring allows the clamping block to adaptively adjust according to the actual size of the laptop shell. When the shell size is small, the clamping block can slide inward under the action of the second spring to better fit the shell; when the shell size is large, the clamping block can slide outward to ensure clamping stability. This design allows the punching equipment to be used for laptop shells of various sizes without changing the clamping device or making complex adjustments, thereby improving the versatility and flexibility of the equipment.

[0024] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] The present utility model provides a punching device for processing a notebook shell as shown in Figure 1-5 Figure 1, which includes a base plate 1. Above the front side of the base plate 1, there is a base 7. Above the base 7, there is a workbench 8. On the left and right sides of the workbench 8, there are mounting plates 9. Inside the mounting plates 9, there are sliding grooves 10. Inside the sliding grooves 10, there are sliders 11. At the top end of the sliders 11, there is a first wedge transmission rod 12. Directly above the first wedge transmission rod 12, there is a second wedge transmission rod 13. On the side wall of the first wedge transmission rod 12, there is a connecting plate 15 which penetrates to the groove inside the workbench 8. Inside the connecting plate 15, there is a through groove 17. Inside the through groove 17, there is a clamping block 16 slidably installed.

[0026] At the rear side above the base plate 1, there is a vertical plate 2. On the front wall of the vertical plate 2, there is a cylinder 3. Below the cylinder 3, there is a top plate 4. The top surface of the top plate 4 is connected to the output end of the cylinder 3. On the left and right sides of the top plate 4, there are guide rods 5 which penetrate and extend to the top surface of the base 7. The connection between the top plate 4 and the guide rods 5 is a sliding connection. The slider 11 is designed in a "convex" shape structure. The connection between the slider 11 and the sliding groove 10 is a sliding connection. The slider 11 and the sliding groove 10 are located on the left and right sides of the workbench 8. There are 2 first wedge transmission rods 12 and 2 second wedge transmission rods 13. The two second wedge transmission rods 13 are respectively located on the left and right sides of the bottom surface of the top plate 4. The two first wedge transmission rods 12 are respectively located on the left and right sides of the base 7. Both the first wedge transmission rod 12 and the second wedge transmission rod 13 have inclined planes, and the inclined planes of the two first wedge transmission rods 12 face in opposite directions, and the inclined planes of the two second wedge transmission rods 13 also face in opposite directions. The inclined plane of the second wedge transmission rod 13 is accurately corresponding to the inclined plane of the first wedge transmission rod 12 in position. Between the slider 11 and the workbench 8, there is a first spring 14. One end of the first spring 14 is installed on the side wall of the slider 11, and the other end of the first spring 14 is installed on the side wall of the workbench 8. Inside the through groove 17, there is a second spring 18. One end of the second spring 18 is installed on the inner wall of the through groove 17, and the other end of the second spring 18 is installed on the side wall of the clamping block 16. There are 2 clamping blocks 16, and the two clamping blocks 16 are located on the left and right sides of the groove of the workbench 8.

[0027] The telescopic movement of cylinder 3 drives the top plate 4 and the punch 6 below it to move up and down, realizing the punching operation of the notebook shell. The guide rod 5 ensures the stability and accuracy of the top plate 4 during the movement, improving the punching quality. At the same time, the first wedge transmission rod 12 and the second wedge transmission rod 13 cooperate to form an effective clamping mechanism. When the top plate 4 descends, the second wedge transmission rod 13 descends synchronously and contacts the first wedge transmission rod 12. Through the sliding connection between the slider 11 and the slide groove 10, the clamping block 16 moves closer to the notebook shell inside the groove of the worktable 8, realizing the clamping of the workpiece. This design allows the punching and clamping operations to be carried out simultaneously, improving processing efficiency. In addition, the second spring 18 gives the clamping block 16 a certain degree of flexibility, which can adapt to notebook shells of different sizes, improving the versatility and flexibility of the equipment.

[0028] A punch 6 is located directly above the workbench 8 and on the bottom surface of the top plate 4. A drain hole 19 is provided in the groove of the workbench 8. The position of the drain hole 19 corresponds to the position of the punch 6. The drain hole 19 extends through to the bottom of the base 7. A collection box 20 is provided below the drain hole 19 and is located above the substrate 1.

[0029] The waste material after punching can fall smoothly through the hole 19 into the collection box 20 below, realizing the centralized collection of waste material, which is convenient for cleaning and maintenance.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual appendix Figure 1-5 When using this utility model, first, accurately place the notebook casing to be punched into the groove of the workbench 8, start the cylinder 3 to extend its output end, and drive the top plate 4 and the punch 6 below it to begin to descend. During the descent of the top plate 4, the second wedge transmission rod 13 descends synchronously and contacts the inclined surface of the first wedge transmission rod 12. Due to the cooperation of the inclined surfaces of the first wedge transmission rod 12 and the second wedge transmission rod 13, and the sliding connection between the slider 11 and the slide groove 10, the slider 11 slides on one side of the workbench 8 within the slide groove 10. The sliding motion of the connecting plate 15 drives the clamping block 16 to move closer to the laptop shell, that is, closer to the laptop shell inside the groove of the worktable 8. When the clamping block 16 has clamped the laptop shell, but the punch 6 has not yet reached the laptop shell, if there are slight differences in the size of the laptop shell or the clamping force needs to be finely adjusted, the clamping block 16 can make slight sliding adjustments inward or outward in the through groove 17 under the action of the second spring 18. This adaptive adjustment allows the clamping block 16 to better fit laptop shells of different sizes, ensuring the stability and accuracy of clamping.

[0032] Meanwhile, the elastic design of the second spring 18 also avoids excessive pressure on the outer shell by the clamping block 16, protecting the outer shell from damage. When the punch 6 continues to descend until it contacts and penetrates the laptop shell, the punching operation is completed. The waste material after punching falls into the collection box 20 below through the drain hole 19 at the groove of the worktable 8, realizing the centralized collection of waste material, which is convenient for subsequent cleaning and maintenance. After punching is completed, the output end of the cylinder 3 retracts, driving the top plate 4 and the punch 6 to rise and reset. At the same time, the slider 11 resets under the action of the first spring 14, driving the clamping block 16 to reset as well, releasing the clamping of the laptop shell, taking out the punched laptop shell, and preparing to perform the punching operation of the next shell.
