[0001] The invention relates to the technical field of computer case production, in particular to a computer case positioning drilling device. Background Art

[0002] In the production process of computer cases, drilling is a very critical process.

[0007] Preferably, a slide groove is provided inside the upper side of the support seat, and the outer wall of the slide plate is slidably connected to the inner side of the upper side of the support seat through the slide groove.

[0008] Preferably, one end of the electric wire away from the power source is connected to the wiring terminal.

[0009] Preferably, the disassembly and assembly mechanism includes a connecting shaft, one end of the connecting shaft is arranged on the outer wall of the magnetic attraction plate, the other end of the connecting shaft is fixedly connected to a top block, the outer wall of the connecting shaft is slidably connected to a disassembly block, the outer wall of the connecting shaft is fixedly connected to a limiting shaft, and the limiting shaft is located on the right side of the disassembly block.

[0010] Preferably, the disassembly and assembly mechanism also includes a disassembly plate, the outer wall of the disassembly plate is fixedly connected to the outer wall of the positioning shell, the interior of the disassembly plate is fixedly connected to a fixed shaft, the outer wall of the fixed shaft is slidably connected to a block, the outer wall of the block is slidably connected to the interior of the disassembly plate, the outer wall of the fixed shaft is slidably connected to a spring 1, one end of the spring 1 is arranged inside the disassembly plate, and the other end of the spring 1 is arranged on the outer wall of the block.

[0011] Preferably, a circular groove is provided in the middle of the disassembly plate.

[0012] Preferably, a motor is fixedly connected to the inside of the support frame, a turntable is connected to the output end of the motor, an outer wall of the turntable is rotatably connected to the inside of the support frame, a belt is provided on the outer wall of the turntable, a rubber baffle is provided on the outer wall of the belt, a plurality of springs 2 are evenly arranged inside the rubber baffle, and a buckle is fixedly connected to the outer wall of the spring 2.

[0013] Preferably, a chassis assembly plate is disposed on the upper surface of the belt, a card slot is provided inside the chassis assembly plate, and an outer wall of the buckle is disposed inside the card slot.

[0014] Preferably, a collection box is provided on the outer wall of the support frame.

[0015] Working principle: The screw needs to be turned according to the size of the hole required. When the screw is turned, its outer wall will rotate inside the positioning block. At the same time, the outer wall of the sliding shaft will slide inside the positioning shell and support the positioning block to limit it. The screw will push the positioning block to adjust the size. When calling back, the gasket will play a limiting role, so that the screw can pull the positioning block to call back. Finally, adjust the four screws inside the positioning shell to the appropriate position to achieve the effect of adjusting the size of the positioning hole of the positioning mechanism according to the needs.

[0016] Then use the wire to connect the connection terminal of the magnetic attraction plate and the output terminal of the power supply, so that the magnetic attraction plate has magnetic force. The connecting shaft is made of a material that can be magnetically attracted by a magnet. Then, according to the required drilling position, a certain number of connecting shafts, top blocks, disassembly blocks and limit shafts are arranged on the outer wall of the magnetic attraction plate, and then the positioning mechanism is installed on the outer wall of the connecting shaft. During installation, align the groove opened in the middle of the disassembly plate with the top block and push it inward. The card block will be pushed by the top block to compress the spring one, and slide on the outer wall of the fixed shaft and the inside of the disassembly plate. When the card block is separated from the surface of the top block, the spring one will push the card block out and it will be stuck in the groove opened inside the connecting shaft; thereby, the position and quantity of the positioning mechanism can be adjusted according to needs.

[0017] The chassis assembly panels are placed vertically on the upper surface of the belt in sequence. During the placement process, the chassis assembly panels will squeeze the arc-shaped surface of the buckle surface, squeezing the buckle to compress the spring 2 and make the buckle snap into the inside of the slot and fix the chassis assembly panel when the chassis assembly panel is placed on the upper surface of the belt, so as to achieve the effect of stabilizing the chassis assembly panel when the worker punches holes;

[0018] When the hydraulic rod is turned on again, the hydraulic rod will push the support plate. When the support plate slides, it will drive the slide plate to slide inside the slide groove to achieve the function of supporting the support plate to slide. The support plate will then push the magnetic plate to drive the positioning mechanism to move to the outer wall of the chassis assembly plate. The magnetic plate will be adsorbed on the outer wall of the chassis assembly plate. At the same time, the card block will be separated from the groove inside the connecting shaft by the pressure pushed by the hydraulic rod, and slide on the outer wall of the disassembly block and reach the outer wall of the limit shaft. Then the hydraulic rod will be reset. At the same time, the magnetic plate will drive the connecting shaft to pull back, and the connecting shaft will drive the disassembly block to slide. In the process of sliding of the disassembly block, the card block will slide with it due to the friction force, and after the disassembly block is attached to the top block, the card block will be pushed to slide by the friction force and the spring will be compressed to separate the card block from the disassembly block, thereby achieving the effect of fast and batch installation of the positioning mechanism.

[0019] The collecting trough can be used to collect the debris generated during the punching process, and when the chassis assembly is driven by the belt to rotate to the side, it can be inverted and continue to be transported. At the same time, after the chassis assembly is inverted, the debris collected inside the collecting trough can fall into the collection box and be automatically collected. When inverted, since only the buckles fix the chassis assembly, the chassis assembly can shake and shake off all the debris.

[0020] The present invention provides a computer case positioning drilling device, which has the following beneficial effects:

[0021] 1. The present invention can adjust the position of the positioning block by rotating the screw to adjust the size of the positioning hole of the positioning mechanism as needed. The adjustability of the size of the positioning hole enables the drilling device to adapt to computer cases of different specifications and types.

[0022] 2. The present invention arranges a certain number of connecting shafts on the outer wall of the magnetic suction plate according to the positions of the required drilling holes, and then installs the positioning mechanism to the outer wall of the connecting shaft, so as to achieve the effect of adjusting the position and number of the positioning mechanism as needed, and can be quickly adjusted according to different design requirements without replacing complex equipment or re-setting complex processes. The production line can quickly adapt to the production needs of various types of chassis, reducing the production cycle and equipment adjustment time of customized products.

[0023] 3. The present invention drives the positioning mechanism to move to the outer wall of the chassis assembly panel by opening the hydraulic rod to push the magnetic plate, and the magnetic plate is adsorbed on the outer wall of the chassis assembly panel, so as to achieve the effect of fast and batch installation of the positioning mechanism. Batch installation of the positioning mechanism can significantly improve the overall efficiency of the production line and avoid the inefficiency and inconsistency of traditional manual installation. The whole process has a high degree of automation, which not only speeds up the production speed, but also reduces the stagnation time in the assembly process.

[0024] 4. The present invention can achieve the effect of stabilizing the chassis assembly when workers are punching holes by making the buckle snap into the inside of the card slot and fixing the chassis assembly. By stabilizing the chassis assembly when punching holes, the deviation of the punching can be effectively reduced, the accuracy and consistency of the hole position can be ensured, and the accuracy of the assembly can be improved.

[0025] 5. The present invention collects the debris generated during the punching process through a collecting groove, and automatically collects the collected debris by shaking it off inside a collecting box. By effectively collecting the debris, the working environment can be kept clean, the interference of the debris on the production process can be reduced, and the comfort of workers at work can be improved.

DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Please refer to the attached Figure 1 and attached Figure 5 To Attachment Figure 7 The embodiment of the present invention provides a computer case positioning drilling device, including a positioning mechanism 1, a support seat 2 and a support frame 12. The positioning mechanism 1 includes a positioning shell 101, the internal thread of the positioning shell 101 is connected with a screw 102, the outer wall of the screw 102 is fixedly connected with a gasket 103, the interior of the positioning shell 101 is slidably connected with a sliding shaft 105, the outer wall of the sliding shaft 105 is fixedly connected with a positioning block 104, the outer wall of the screw 102 is rotatably connected to the interior of the positioning block 104, the outer wall of the gasket 103 is rotatably connected to the interior of the positioning block 104, the outer wall of the positioning shell 101 is fixedly connected with a support frame 106, the interior of the support frame 106 is fixedly connected with a magnetic plate 107, and the interior of the support frame 106 is provided with a collecting groove 108.

[0039] Specifically, first, the screw 102 needs to be rotated according to the size of the hole required. When the screw 102 is rotated, its outer wall will rotate inside the positioning block 104. At the same time, the outer wall of the sliding shaft 105 will slide inside the positioning shell 101 and support the positioning block 104 to limit it. The screw 102 will push the positioning block 104 to adjust the size. When calling back, the gasket 103 will play a limiting role, so that the screw 102 can pull the positioning block 104 to call back. Finally, the four screws 102 inside the positioning shell 101 are adjusted to the appropriate position to achieve the effect of adjusting the size of the positioning hole of the positioning mechanism 1 as required. The adjustability of the size of the positioning hole enables the drilling device to adapt to computer chassis of different specifications and types. For example, chassis of different brands or models may require holes of different sizes and layouts to install various hardware components, such as motherboards, hard disks, etc. By adjusting the size of the positioning hole, the drilling device can meet these different needs, ensuring that even in highly personalized or specially customized chassis designs, the device can accurately and efficiently complete the drilling task, thereby greatly improving the versatility of the device.

[0040] Please refer to the attached Figure 1 To Attachment Figure 4 The upper surface of the support seat 2 is fixedly connected with a hydraulic rod 3, the output end of the hydraulic rod 3 is connected with a support plate 4, the lower surface of the support plate 4 is fixedly connected with a slide plate 5, the upper right surface of the support plate 4 is fixedly connected with a power supply 7, the upper left surface of the support plate 4 is fixedly connected with a magnetic plate 8, the magnetic plate 8 is provided with a wiring terminal 9, the output end of the power supply 7 is connected with a wire 10, and the outer wall of the magnetic plate 8 is provided with a disassembly mechanism 11. A slide groove 6 is provided inside the upper side of the support seat 2, and the outer wall of the slide plate 5 is slidably connected to the upper side of the support seat 2 through the slide groove 6. The end of the wire 10 away from the power supply 7 is connected to the wiring terminal 9. The disassembly mechanism 11 includes a connecting shaft 1101, one end of which is arranged on the outer wall of the magnetic plate 8, the other end of which is fixedly connected to a top block 1102, a disassembly block 1103 is slidably connected to the outer wall of the connecting shaft 1101, a limit shaft 1104 is fixedly connected to the outer wall of the connecting shaft 1101, and the limit shaft 1104 is located on the right side of the disassembly block 1103. The disassembly mechanism 11 also includes a disassembly plate 1105, the outer wall of the disassembly plate 1105 is fixedly connected to the outer wall of the positioning shell 101, the interior of the disassembly plate 1105 is fixedly connected to a fixed shaft 1106, the outer wall of the fixed shaft 1106 is slidably connected to a clamping block 1107, the outer wall of the clamping block 1107 is slidably connected to the interior of the disassembly plate 1105, the outer wall of the fixed shaft 1106 is slidably connected to a spring 1108, one end of the spring 1108 is arranged inside the disassembly plate 1105, and the other end of the spring 1108 is arranged on the outer wall of the clamping block 1107. A circular groove is formed in the middle of the disassembly plate 1105 .

[0041] Specifically, the wire 10 is used to connect the terminal 9 of the magnetic plate 8 and the output end of the power supply 7, so that the magnetic plate 8 has magnetic force. The connecting shaft 1101 is made of a material that can be magnetically attracted by a magnet, such as iron, and then a certain number of connecting shafts 1101, top blocks 1102, disassembly blocks 1103 and limit shafts 1104 are arranged on the outer wall of the magnetic plate 8 according to the required drilling positions, and then the positioning mechanism 1 is installed to the outer wall of the connecting shaft 1101. During installation, the groove in the middle of the disassembly plate 1105 is aligned with the top block 1 If 102 is pushed inward again, the block 1107 will be pushed by the top block 1102 to compress the spring 1108, and slide on the outer wall of the fixed shaft 1106 and the inside of the disassembly plate 1105. When the block 1107 is separated from the surface of the top block 1102, the spring 1108 will push the block 1107 out and get stuck in the groove opened inside the connecting shaft 1101; thereby, the position and quantity of the positioning mechanism 1 can be adjusted according to the needs. Chassis of different models and specifications may have different hole layouts and quantity requirements. The position and quantity of the positioning mechanism 1 can be adjusted quickly according to different design requirements without replacing complex equipment or resetting complex processes. The production line can quickly adapt to the production needs of various types of chassis, reducing the production cycle and equipment adjustment time of customized products;

[0042] Then turn on the hydraulic rod 3. When the hydraulic rod 3 starts, it will push the support plate 4. When the support plate 4 slides, it will drive the slide plate 5 to slide inside the slide groove 6 to support the support plate 4 to slide. The support plate 4 then pushes the magnetic plate 8 to drive the positioning mechanism 1 to move to the outer wall of the chassis assembly plate 19. The magnetic plate 107 will be adsorbed on the outer wall of the chassis assembly plate 19. At the same time, the block 1107 will be pushed by the pressure of the hydraulic rod 3 to break away from the groove inside the connecting shaft 1101 and slide on the outer wall of the disassembly block 1103 and reach the outer wall of the limit shaft 1104. Then the hydraulic rod 3 is reset, and the hydraulic rod 3 is moved forward. While resetting, the magnetic plate 8 will drive the connecting shaft 1101 to pull back, and the connecting shaft 1101 will drive the disassembly block 1103 to slide. During the sliding process of the disassembly block 1103, the friction force will drive the card block 1107 to slide with it, and after the disassembly block 1103 is attached to the top block 1102, the card block 1107 is pushed by the friction force to slide and compress the spring 1108 to make the card block 1107 separate from the disassembly block 1103, so that the effect of fast and batch installation of the positioning mechanism 1 can be achieved. The batch installation of the positioning mechanism 1 can significantly improve the overall efficiency of the production line. In the process of mass production, the automated equipment can install multiple positioning mechanisms 1 on the chassis board at the same time, avoiding the inefficiency and inconsistency of traditional manual installation. The whole process has a high degree of automation, which not only speeds up the production speed, but also reduces the stagnation time in the assembly process.

[0043] Please see attached Figure 1 and attached Figure 8 To Attachment Fig.10 The support frame 12 is fixedly connected with a motor 13 inside, the output end of the motor 13 is connected with a turntable 14, the outer wall of the turntable 14 is rotatably connected to the inside of the support frame 12, the outer wall of the turntable 14 is provided with a belt 15, the outer wall of the belt 15 is provided with a rubber baffle 16, a plurality of springs 17 are evenly provided inside the rubber baffle 16, and the outer wall of the spring 17 is fixedly connected with a buckle 18. The upper surface of the belt 15 is provided with a chassis assembly plate 19, the inside of the chassis assembly plate 19 is provided with a card slot 20, and the outer wall of the buckle 18 is arranged inside the card slot 20. The outer wall of the support frame 12 is provided with a collection box 21.

[0044] Specifically, the motor 13 is turned on to make the belt 15 start to rotate, and the iron or steel chassis assembly plate 19 is placed vertically on the upper surface of the belt 15 in sequence. When the chassis assembly plate 19 is made of a material that cannot be magnetically attracted, a suction cup can be set on the outer wall of the magnetic plate 107 to replace the role of the magnet. During the placement process, the chassis assembly plate 19 will squeeze the arc-shaped surface of the buckle 18 surface, squeezing the buckle 18 to compress the spring 217 and when the chassis assembly plate 19 is placed on the upper surface of the belt 15, the buckle 18 is clamped to the inside of the card slot 20 and the chassis assembly plate 19 is fixed, so that the chassis assembly plate 19 can be stabilized when the worker punches holes. When the chassis assembly plate 19 is not stabilized, a slight displacement or vibration may occur during the punching process, resulting in offset or asymmetry of the hole position. By stabilizing the chassis assembly plate 19 when punching holes, these deviations can be effectively reduced, ensuring the accuracy and consistency of the hole position, thereby improving the accuracy of assembly.

[0045] Debris will be generated during the punching process, and the collection slot 108 can be used to collect the debris generated during the punching process, and when the chassis assembly plate 19 is driven by the belt 15 to rotate to the side, it will be inverted and continue to be transported. At the same time, after the chassis assembly plate 19 is inverted, the debris collected in the collection slot 108 can fall into the collection box 21 for automatic collection. When inverted, since only the buckle 18 fixes the chassis assembly plate 19, the chassis assembly plate 19 can shake and shake off all the debris. The debris (such as metal shavings) generated during the punching will be scattered on the workbench and the ground, increasing the workload of cleaning and may interfere with the workers' operations. By effectively collecting debris, the working environment can be kept clean, the interference of debris on the production process can be reduced, and the comfort of workers at work can be improved.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
