[0038] Embodiments

[0039] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present embodiment provides a drilling machine, including a shell 10, a drilling unit 20 and a control circuit board 30, a linear slide rail 101 is arranged on one side of the shell 10, and a vacuum adsorption unit 102 for fixing itself is arranged at the bottom of the shell 10; the drilling unit 20 includes a sliding block 201 which is in sliding fit with the linear slide rail 101, a drilling motor 202 arranged on the sliding block 201, and a driving unit 203 for driving the sliding block 201 to slide on the linear slide rail 101, a chuck for clamping a drill bit is mounted on the output shaft of the drilling motor 202, and the chuck can be adjusted in tightness to adapt to different drill bits. The control circuit board 30 is arranged in the shell 10, the drilling motor is electrically connected with a first output end of the control circuit board 30, and the vacuum adsorption unit is electrically connected with a second output end of the control circuit board 30. A storage battery or other rechargeable battery can be used for power supply, or a power line can be directly connected to a commercial power supply for power supply use.

[0040] Specifically, the sliding block 201 is driven by the driving unit 203 to ensure that the drilling motor 202 moves stably on the linear slide rail 101, so as to realize high-precision punching; and after completing a punching operation, the drilling machine can be automatically reset for the next punching operation. The vacuum adsorption unit 102 is fixed and installed on the drilling machine by means of vacuum adsorption, so as to prevent displacement during operation and ensure the stability of drilling. In addition, the vacuum adsorption fixing can fix the drilling machine on a wall surface, a table top or a board surface, or the top surface of a building or an object, and only a flat surface is needed for vacuum adsorption installation, which has the effect of flexible installation, so as to ensure the precision and quality of drilling.

[0041] The control circuit board 30 is integrated with a microprocessor, which can be of the STM32F103C8T6 model. This model of microprocessor has high data processing capacity, ensuring accurate control of the drilling operation. It achieves precise start, stop and speed regulation of the drilling motor 202, ensuring automation and efficiency of the drilling process. In addition, it controls the start and stop of the vacuum suction unit 102, enabling quick fixing and release of the drilling machine, further improving operational convenience and work efficiency.

[0042] Further, the shell 10 in the embodiment is provided with a limiting rod 103 arranged in parallel with the linear slide rail 101, the sliding block 201 is provided with a through hole for sliding cooperation with the limiting rod 103, and the middle part of the limiting rod 103 is provided with a limiting shoulder 1031 for limiting the top of the sliding block 201. The design of the limiting shoulder 1031 effectively prevents the sliding block 201 from exceeding the predetermined range during sliding, forming a limiting effect on the stroke of the sliding block 201, ensuring the accuracy and safety of the drilling operation; at the same time, the depth of the drilling can be adjusted, so that after the sliding block 201 abuts against the limiting shoulder 1031 during drilling, it can be automatically reversed and reset upward, and the drilling motor stops after resetting. Further, the design of the limiting rod 103 enhances the stability of the overall structure, avoiding errors caused by excessive movement of the sliding block 201. The precise cooperation between the limiting shoulder 1031 and the through hole further improves the controllability of the drilling process, ensuring accurate positioning of each operation, thereby ensuring the drilling quality and prolonging the service life of the equipment.

[0043] Further, as shown in Figure 3 The driving unit 203 includes a threaded rod 2031 threadedly cooperating with the sliding block 201, a first gear 2032 arranged on one end of the threaded rod 2031, a driving motor 2033, and a second gear 2034 arranged on the output shaft of the driving motor 2033. The first gear 2032 is meshed with the second gear 2034, and the threaded rod 2031 is arranged side by side with the driving motor 2033 on the bottom plate of the shell 10.

[0044] The threaded rod 2031 achieves power transmission of the driving motor 2033 through the meshing of the first gear 2032 and the second gear 2034, drives the sliding block 201 to move up and down, and makes the drilling motor 202 move synchronously to drill, thereby achieving accurate adjustment of the drilling position. The efficient operation of the driving motor 2033 ensures smooth movement of the sliding block 201, reduces vibration and noise, and improves the stability and comfort of the drilling process. The precise cooperation between the threaded rod 2031 and the gears further optimizes the power transmission efficiency, prolongs the service life of the equipment, and ensures long-term stable operation.

[0045] As shown in Figure 3As shown, the vacuum suction unit 102 in this embodiment includes a vacuum pump 1021, a suction disc seat 1022 arranged on the ground of the shell 10, and a vacuum suction disc 1023 arranged on the suction disc seat 1022. The suction port of the vacuum pump 1021 is arranged through the suction disc seat 1022 or the vacuum suction disc 1023. If the vacuum suction disc 1023 is in a ring structure, the suction port of the vacuum pump 1021 can be communicated to the suction disc seat 1022. If the vacuum suction disc 1023 is in a sheet structure (with a concave surface, i.e., a horn surface), the suction port of the vacuum pump 1021 is communicated to the vacuum suction disc 1023. When vacuum suction on a plane is needed, the vacuum pump 1021 is started to perform vacuum suction, so that the vacuum suction disc 1023 is tightly attached to the plane to form strong suction force, thereby ensuring that the equipment is stable and does not move. At the same time, the accuracy and quality of the drilling machine drilling can be ensured.

[0046] Further, the vacuum suction disc 1023 can be made of silica gel or sponge material, which has excellent elasticity and sealing performance, effectively adapts to different surface materials, and enhances the suction effect. The silica gel suction disc is wear-resistant and anti-aging, prolongs the service life, ensures long-term stable suction, and improves the reliability and safety of the drilling operation. The vacuum suction disc 1023 made of sponge material has better softness and adhesion, which is suitable for uneven surfaces, provides uniform suction force, reduces errors caused by uneven surfaces, and further improves drilling accuracy and stability.

[0047] As shown in Figure 1 and Figure 3 , the top of the shell 10 is provided with a plurality of control buttons 104, and the plurality of control buttons 104 are electrically connected with the input end of the control circuit board 30. The functions of the device are controlled by operating the control buttons 104, which can be started by one key and automatically reset after each drilling for the next drilling. Further, the control buttons 104 include a vacuum suction button 1041, a drilling button 1042, a stop button 1043, and a rotation speed adjustment button 1044. Each control button is designed with a corresponding name for identification, so that the function of the button can be known, the operation is simple and not prone to errors, the user can quickly switch functions according to actual needs, and the working efficiency is improved.

[0048] As shown in Figure 1 and Figure 3As shown, the top of the housing 10 in this embodiment is provided with a plurality of indicator lights 105, and the plurality of indicator lights 105 are electrically connected to the third output end of the control circuit board 30. The indicator lights 105 can be vacuum adsorption indicator lights 105 and drilling indicator lights 105, and can visually display the current working state (for example, flashing for running, off or running end for stopping running, and constant light for the state of being in operation) through different colors or flashing frequencies, so as to facilitate the user to monitor the equipment operation in real time and ensure the operation safety. The eye-catching design of the indicator lights 105 can be clearly visible even in an insufficient light environment, further improving the ease of use and user experience of the equipment. Through the real-time feedback of the indicator lights 105, the user can quickly identify the equipment state, avoid misoperation, and improve the accuracy of drilling operation.

[0049] As shown in Figure 3 , the embodiment also includes a sliding table 40, and the linear sliding rail 101 is arranged on the sliding table 40. The housing 10 is recessed on one side to form a receiving groove for mounting the sliding table 40. The design of the sliding table 40 can form a two-part assembly structure, which improves the structural strength of the position of the sliding table 40 to adapt to the installation and stable operation of the drilling motor 202. The precise positioning and movement during drilling are realized, and the accuracy of the drilling position is ensured.

[0050] As shown in Figure 1 and Figure 2 , the other side of the housing 10 in this embodiment is provided with a finger groove structure 106 or a non-slip texture structure. The design of the finger groove structure 106 facilitates the user to hold and move the equipment, and increases the operation flexibility. The finger groove surface is made of non-slip material (such as rubber surface or silicone surface, etc.), which improves the comfort of holding, ensures the stability of hands during drilling, and avoids errors caused by hand slipping. At the same time, the position of the finger groove is reasonable, which conforms to the principle of ergonomics, reduces the hand fatigue of long-time operation, and further improves the work efficiency and drilling precision.

[0051] Alternatively, a non-slip texture structure can be designed on the side surface of the housing 10, such as a mesh-like texture, a dot-like texture or a strip-like texture, etc., to enhance the friction and prevent slipping. This design not only improves the holding stability, but also effectively meets the operation demand in a wet environment, ensures accurate control under various conditions, and further optimizes the user experience.

[0052] As shown in Figure 1 and Figure 2 , the bottom of the housing 10 in this embodiment is provided with a drilling table plate 107, and the drilling table plate 107 is provided with an avoidance through hole coaxially arranged with the output shaft of the drilling motor 202. In this way, the article to be drilled can be placed on the drilling table plate 107, and the position can be judged and adjusted through the avoidance through hole, so as to ensure the accuracy of the drilling position.

[0053] Further, the anti-skid pads of wear-resistant material can be used on the surface of the drilling platform plate 107 to prevent articles from sliding and prolong the service life, and further improve the safety and stability of the drilling operation.

[0054] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
