Description

Technical Field

[0001] This utility model relates to the field of PCB board drilling technology, specifically a stable clamp for drilling PCB boards. Background Technology

[0002] A PCB (Printed Circuit Board) is the support structure and electrical connection carrier for electronic components. It achieves electrical connections or insulation between electronic components by printing conductive patterns on an insulating substrate. PCBs are typically made of copper-clad laminate, with circuit patterns formed through etching. Various electronic components, such as resistors, capacitors, and chips, can be mounted on its surface and fixed with solder to achieve electrical connections. With the development of electronic technology, the number of layers in PCBs has continuously increased, from single-layer and double-layer to multi-layer boards, to meet the needs of complex circuits. It is widely used in computers, communication equipment, consumer electronics, and other fields, and is an indispensable core component of modern electronic devices.

[0003] Existing PCB drilling fixtures generally suffer from poor adaptability, low adjustment accuracy, and insufficient support. For example, fixed-spacing clamping components cannot be adapted to PCBs of different sizes, resulting in insecure clamping or positioning deviations; the adjustment process relies on manual operation, which is inefficient and prone to errors; during drilling, the PCB lacks local support, and the suspended areas are prone to deformation due to excessive force, affecting hole accuracy and board integrity. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a stable clamp for drilling PCB boards, including a worktable, a movable clamping assembly installed on the top of the worktable, and a fixed clamping assembly fixedly connected to the top of the worktable.

[0005] The movable clamping assembly includes a mounting sleeve, inside which a servo motor is installed. A gear is fixedly connected to the output end of the servo motor, and a rack is meshed with the surface of the gear. A connecting platform is fixedly connected to the left end of the rack, and a pressing platform is fixedly connected to the end of the connecting platform away from the rack. A threaded sleeve is fixedly connected to the top of the pressing platform, and a threaded rod is threadedly connected inside the threaded sleeve. A pressing plate is fixedly connected to the bottom of the threaded rod. A spring is sleeved on the surface of the rack. A mounting box is fixedly connected to the top of the worktable, and a slide rail is installed on the inner wall of the mounting box. A slider is slidably connected inside the slide rail.

[0006] The above technical solution uses a servo motor to drive a gear and rack, which in turn moves the connecting platform and the pressing platform, thereby achieving precise adjustment of the distance between the two clamping components and adapting to PCB boards of different sizes.

[0007] As a further improvement to the above solution, the rack passes through the mounting box, the connecting platform is located inside the mounting box, and the left and right ends of the spring are respectively fixed to the connecting platform and the inner wall of the mounting box.

[0008] Through the above technical solution, the design of the rack penetrating the mounting box allows the connecting platform to move along the inside of the mounting box under the drive of the rack.

[0009] As a further improvement to the above solution, the threaded rod extends through the top of the pressing table.

[0010] Through the above technical solution, the threaded rod passes through the top of the pressing table and cooperates with the threaded sleeve, so that the pressing plate can be pressed down vertically under the drive of the threaded rod, and the pressure is applied evenly. This ensures that the PCB board remains stable during the clamping process and avoids problems such as insecure clamping or uneven force caused by the deviation of the threaded rod.

[0011] As a further improvement to the above solution, the number of slide rails is set to two, and the two slide rails are evenly distributed on the inner wall with the top center of the mounting box symmetrically arranged.

[0012] With the above technical solution, the two slide rails are symmetrically distributed around the top center of the mounting box, providing stable guidance for the slider and ensuring the linear motion accuracy of the connecting platform during movement.

[0013] As a further improvement to the above solution, the end of the slider away from the slide rail is fixedly connected to the surface of the connecting platform.

[0014] Through the above technical solution, the fixed connection between the slider and the connecting platform enables the moving clamping component to slide smoothly along the slide rail during the adjustment process, avoiding adjustment errors or equipment failures caused by loose connections.

[0015] As a further improvement to the above solution, a hydraulic telescopic rod is installed inside the workbench, and a support platform is fixedly connected to the output end of the hydraulic telescopic rod. A slide bar is fixedly connected to the top of the support platform, and a slide rail is slidably connected to the surface of the slide bar.

[0016] Through the above technical solution, the hydraulic telescopic rod drives the support platform to move, providing support for the exposed parts of the PCB board during drilling, avoiding deformation caused by uneven force due to suspension. The support platform is located between the moving clamping component and the fixed clamping component, ensuring the accuracy and effectiveness of the support position.

[0017] As a further improvement to the above solution, the top of the slide rail two is fixedly connected to the bottom of the worktable, the support platform is located between the movable clamping assembly and the fixed clamping assembly, and the top of the support platform and the bottom of the inner wall of the pressing table are on the same plane.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention features a pressing platform and a support platform. A servo motor drives a gear and rack to move the connecting platform and the pressing platform, enabling precise adjustment of the distance between the two clamping components to accommodate PCBs of different sizes. The fixed clamping components and the moving clamping components work together, using threaded rods and pressing plates to firmly fix the PCBs. A hydraulic telescopic rod drives the support platform to move, providing local support for the PCBs during drilling and preventing deformation due to uneven stress caused by suspension. This ensures the stability and accuracy of the PCBs during drilling and improves the versatility of the mold. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-5 A stabilizing fixture for drilling PCB boards according to this embodiment includes a worktable 1, a movable clamping assembly 2 installed on the top of the worktable 1, and a fixed clamping assembly 7 fixedly connected to the top of the worktable 1.

[0029] The movable clamping assembly 2 includes a mounting sleeve 21, inside which a servo motor 22 is installed. A gear 23 is fixedly connected to the output end of the servo motor 22. A rack 24 is meshed with the surface of the gear 23. A connecting platform 25 is fixedly connected to the left end of the rack 24. A pressing platform 26 is fixedly connected to the end of the connecting platform 25 furthest from the rack 24. A threaded sleeve 27 is fixedly connected to the top of the pressing platform 26. A threaded rod 28 is threadedly connected inside the threaded sleeve 27. A pressing plate 29 is fixedly connected to the bottom of the threaded rod 28. The surface of the rack 24... A spring 210 is fitted onto the surface of the worktable 1. A mounting box 211 is fixedly connected to the top of the worktable 1. A slide rail 212 is installed on the inner wall of the mounting box 211. A slider 213 is slidably connected inside the slide rail 212. When the servo motor 22 is started, the output end of the servo motor 22 drives the gear 23 to rotate. The rotation of the gear 23 drives the rack 24 to move. When the rack 24 moves, it drives the connecting table 25 to move, and simultaneously adjusts the distance between the two moving clamping components 2 and the fixed clamping component 7.

[0030] The rack 24 passes through the mounting box 211, the connecting platform 25 is located inside the mounting box 211, and the left and right ends of the spring 210 are fixed to the connecting platform 25 and the inner wall of the mounting box 211, respectively.

[0031] The threaded rod 28 passes through the top of the pressing table 26.

[0032] There are two slide rails 212, which are symmetrically and evenly distributed on the inner wall of the mounting box 211 with the top center of the box 211 as the slide rails 212 are provided.

[0033] The end of slider 213 away from slide rail 212 is fixedly connected to the surface of connecting platform 25.

[0034] The workbench 1 is equipped with a hydraulic telescopic rod 3. The output end of the hydraulic telescopic rod 3 is fixedly connected to a support platform 4. The top of the support platform 4 is fixedly connected to a slide bar 5. The surface of the slide bar 5 is slidably connected to a slide rail 6. When the hydraulic telescopic rod 3 is activated, the output end of the hydraulic telescopic rod 3 drives the support platform 4 to move. During the movement, the bottom of the end of the PCB board away from the hydraulic telescopic rod 3 will gradually detach from the support platform 4.

[0035] The top of slide rail 26 is fixedly connected to the bottom of worktable 1. Support platform 4 is located between movable clamping assembly 2 and fixed clamping assembly 7. The top of support platform 4 and the bottom of the inner wall of pressing table 26 are on the same plane.

[0036] The implementation principle of a stabilizing fixture for drilling PCB boards in this embodiment is as follows: When drilling PCB boards, the servo motor 22 is started, and the output end of the servo motor 22 drives the gear 23 to rotate. The rotation of the gear 23 drives the rack 24 to move. When the rack 24 moves, it drives the connecting platform 25 to move, and simultaneously adjusts the distance between the two moving clamping components 2 and the fixed clamping component 7. After the adjustment is completed, the PCB board is placed inside the pressing platform 26 and the pressing platform of the fixed clamping component 7. By rotating the handle, the threaded rod 28 rotates inside the threaded sleeve 27, and simultaneously drives the pressing plate 29 to move downward, thus fixing the PCB board.

[0037] When drilling is performed, the hydraulic telescopic rod 3 is activated. The output end of the hydraulic telescopic rod 3 drives the support platform 4 to move. During the movement, the bottom of the PCB board away from the hydraulic telescopic rod 3 will gradually detach from the support platform 4, exposing the drilling position. This prevents the PCB board from deforming due to excessive drilling pressure caused by the lack of bottom support after clamping.

[0038] Once the support platform 4 has moved to half the diameter of the PCB board, its position is reversed and fixed, and the drilling work on the other half of the PCB board is carried out.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
