Description

Technical Field

[0001] This utility model relates to the field of PCB drilling machine technology, and in particular to an auxiliary drilling device for a drilling machine. Background Technology

[0002] In the printed circuit board (PCB) drilling industry, to prevent warping around the holes during drilling and thus reduce drilling accuracy, drilling aids are typically used. These aids are placed around the area to be drilled on the PCB to allow the drill bit to perform precise drilling. However, PCBs may require drilling holes of different diameters, necessitating frequent changes to the drill bit size. The opening for changing the drill bit is often blocked by the drilling aid, requiring the entire aid to be disassembled each time a drill bit is changed. This undoubtedly increases overall operation time and reduces PCB drilling efficiency. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] In view of the problems existing in the prior art, this utility model is proposed.

[0005] Therefore, the present invention aims to provide a drilling machine auxiliary drilling device, which can directly replace the drill bit of the drilling machine located in the drill opening through the exposed drill opening, so as to shorten the overall operation time and improve the drilling efficiency of printed circuit boards.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drilling machine auxiliary drilling device, comprising a hollow base for accommodating a drilling machine drill bit; a connecting base disposed on one side of the hollow base, the connecting base having an arc-shaped groove and a drilling opening, the drilling opening communicating with the arc-shaped groove, the drilling machine drill bit extending from the hollow base into the drilling opening; multiple movable sliders movably disposed in the arc-shaped groove, each movable slider having a pressure plate seat; and displacement driving components disposed around the connecting base and connected to the movable sliders respectively, to drive each movable slider to move dispersedly on the arc-shaped groove.

[0007] In a preferred embodiment of the drilling machine auxiliary drilling device of the present invention, the number of the movable slider and the displacement driving member are both two, and the two displacement driving members respectively drive the two movable sliders to move along the arc-shaped groove.

[0008] As a preferred embodiment of the drilling machine auxiliary drilling device of the present invention, when the two movable sliders move in opposite directions to the opposite ends of the connecting base, the two movable sliders separate from each other, the drilling opening is completely exposed between the two movable sliders, and there is no pressure plate seat above it to block it.

[0009] In a preferred embodiment of the drilling machine auxiliary drilling device of the present invention, when the drilling opening is exposed, the drilling machine drill bit can be taken out or inserted into the hollow base in a vertical direction through the drilling opening.

[0010] In a preferred embodiment of the drilling machine auxiliary drilling device of the present invention, the drilling opening is located at the center of the arc-shaped groove.

[0011] In a preferred embodiment of the drilling machine auxiliary drilling device of the present invention, the displacement driving member can drive the movable slider so that the pressure plate seat of any of the movable sliders is aligned with the drilling opening in the vertical direction, so that the drill bit of the drilling machine can pass through.

[0012] As a preferred embodiment of the drilling machine auxiliary drilling device of the present invention, each of the movable sliders has a pressure plate seat with a guide hole of a different size to accommodate drilling machine bits of different diameters.

[0013] In a preferred embodiment of the drilling machine auxiliary drilling device of the present invention, the pressure plate seat is used to abut against the printed circuit board, and the drill bit of the drilling machine performs drilling operation on the printed circuit board via the aligned pressure plate seat.

[0014] The beneficial effects of this invention are as follows: By driving a movable slider along an arc-shaped groove using a displacement drive, the drill opening and drill bit are directly exposed. This eliminates the need to disassemble the entire device when changing drill bits, significantly reducing auxiliary time and improving the efficiency of printed circuit board drilling operations. Simultaneously, the movable slider drives pressure plates of different diameters to align sequentially with the drill opening, reliably clamping the board to prevent warping and ensuring drilling accuracy. It also allows for quick adaptation to drill bits of different diameters, enhancing the equipment's versatility and processing flexibility. This compact and reasonable structure, coupled with its ease of operation, effectively solves the problem of low efficiency caused by frequent drill bit changes, making it suitable for high-density, multi-specification precision drilling applications.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0026] Example 1, referring to Figures 1-3This is the first embodiment of the present invention, which provides a drilling machine auxiliary drilling device 100. The drilling machine auxiliary drilling device 100 includes a hollow base 110, a connecting base 120, a movable slider 130, and a displacement driving component 140. The hollow base 110 is used to accommodate the drill bit 200 of the drilling machine.

[0027] Specifically, the hollow base 110 is usually made of metal and has a hollow accommodating space inside for mounting and fixing the main body of the drilling machine (not shown in the figure) and allowing the drill bit 200 of the drilling machine to extend downward.

[0028] A connecting base 120 is disposed on one side of the hollow base 110, specifically below the hollow base 110. The connecting base 120 has an arc-shaped groove 122 and a drill opening 124 located on the arc-shaped groove 122, through which a drill bit 200 extends from the hollow base 110 into the drill opening 124. A plurality of movable sliders 130 are movably disposed in the arc-shaped groove 122, each movable slider 130 having a pressure plate seat 132.

[0029] Displacement drive members 140 are disposed around the connecting base 120 and are respectively connected to a plurality of movable sliders 130. The number of displacement drive members 140 corresponds to the number of movable sliders 130, and each displacement drive member 140 is connected to one movable slider 130. The displacement drive members 140 are used to drive the movable sliders 130 to move away from each other along the arc-shaped groove 122 to expose the drill opening 124 and the drill bit 200 therein.

[0030] It is worth noting that the displacement drive 140 can be, but is not limited to, the following specific forms: a cylinder, a hydraulic cylinder, an electric actuator, or a screw-nut mechanism driven by a motor. For example, in a specific embodiment, the displacement drive 140 is a small cylinder, the cylinder body of which is fixed on the connecting base 120, and the end of the piston rod is hinged to the moving slider 130 through a connecting block.

[0031] Specifically, the displacement drive 140 drives the moving slider 130 to move along the arc-shaped slide groove 122 to opposite sides, exposing the drill opening 124 and the drill bit 200. In this way, when it is necessary to replace drill bits of different sizes, the entire device does not need to be disassembled; the replacement can be done directly through the drill opening 124, thereby improving efficiency.

[0032] In one embodiment, there are two movable sliders 130 and two displacement drive members 140, with the two movable sliders 130 located at opposite ends of the arc-shaped groove 122. In other embodiments, there may be more than two movable sliders 130.

[0033] When the two movable sliders 130 move to opposite ends of the connecting base 120, the drill hole opening 124 is located between them. When the two movable sliders 130 move away from each other, the drill hole opening 124 is not obstructed by the pressure plate seat 132, and the two movable sliders 130 separate from each other.

[0034] At this point, the drill bit 200 can be removed and replaced from the hollow base 110 through the drilling opening 124. This allows for direct replacement of the drill bit when drilling holes of different diameters, eliminating the need to disassemble the device and improving efficiency.

[0035] Example 2, refer to Figures 4-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, a pressure plate seat 132 is fixedly installed below each movable slider 130. The pressure plate seat 132 is usually made of wear-resistant material (such as alloy steel or engineering plastic) and has a guide hole machined in its center to guide the drill bit 200 and press the printed circuit board 300 during drilling.

[0037] In a preferred embodiment, the guide hole diameters on the two pressure plate seats 132 can be different, such as... Figure 4 and Figure 5 In the middle, the pressure plate seat 132 of the right movable slider 130 has a smaller aperture, which is suitable for smaller drill bits 200; Figure 6 and Figure 7 In the middle, the pressure plate seat 132 of the left movable slider 130 has a larger hole diameter, which is suitable for larger drill bits 200.

[0038] The drill opening 124 is located at the center of the arc-shaped groove 122. The displacement drive 140 drives the moving slider 130 to move, so that one of the pressure plates 132 is aligned with the drill opening 124 in the vertical direction V. Multiple pressure plates 132 can be sequentially aligned with the drill opening 124 to allow drill bits 200 of different sizes to pass through and abut against the printed circuit board 300 for drilling.

[0039] During drilling operations, the displacement drive 140 drives two movable sliders 130 to move towards each other along the arc-shaped groove 122, causing the pressure plate seat 132 of one of the movable sliders 130 to move directly below the drilling opening 124 and align with the drilling opening 124 in the vertical direction V. At this time, the drill bit 200 can pass through the guide hole of the pressure plate seat 132 to drill the printed circuit board 300 below. The pressure plate seat 132 also serves to press the board and prevent warping.

[0040] When it is necessary to replace the drill bit 200 with one of different diameters, the displacement drive 140 drives two moving sliders 130 to move in opposite directions along the arc-shaped groove 122. For example... Figure 4 and Figure 5As shown, the two movable sliders 130 eventually move to opposite ends of the connecting base 120 and separate from each other. At this point, the drill opening 124 is fully exposed between the two movable sliders 130, with no other components obstructing it. The operator can directly remove the current drill bit 200 from the hollow base 110 along the vertical direction V through the exposed drill opening 124 and replace it with a new drill bit, without disassembling the entire auxiliary drilling device 100.

[0041] After the drill bit is replaced, the displacement drive 140 can drive the moving slider 130 to move again. If the diameter of the newly replaced drill bit changes, another pressure plate seat 132 with a corresponding hole diameter guide hole can be moved to below the drill hole opening 124 and aligned to start a new drilling operation.

[0042] In summary, this utility model, through its ingenious sliding opening and closing structure, enables rapid replacement of drill bits and flexible positioning of the pressure plate seat, significantly improving production efficiency and equipment versatility.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
