Description

Technical Field

[0001] This utility model relates to a magnetic portable brushless motor drilling and tapping machine, which is a drilling machine that uses a brushless motor as the rotational driving force. Background Technology

[0002] This drilling and tapping machine is a very practical processing device that is easy for users to carry and can be used to drill and tap large, difficult-to-move workpieces.

[0003] Currently, the motors installed in magnetic drilling and tapping machines on the market are generally carbon brush motors and AC induction three-phase motors. Among them, portable drilling and tapping machines mainly use carbon brush motors because three-phase power supplies and three-phase sockets are not always available when you are out and about.

[0004] However, carbon brush motors have many drawbacks in practical applications. For example, carbon powder will accumulate after prolonged use, and this powder will adhere to the inside of the motor, which can lead to leakage in severe cases. The carbon brushes will also wear down with continuous use, so they must be replaced when they wear down to a certain extent. If the carbon brushes are not replaced in time, the excessively worn carbon brushes may generate excessive sparks during friction, which can be dangerous if there are flammable materials in the working environment. In addition, the drilling and tapping machine will frequently rotate forward and reverse during use, which will cause further wear on the carbon brushes and commutator, making the motor prone to failure. The noise generated during operation will also cause discomfort to the operator and affect their hearing over time. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic portable brushless motor drilling and tapping machine, which uses a brushless motor instead of a carbon brush motor as the rotational driving force. The housing part of the control module is designed to hold a capacitor slot. The part with the capacitor slot in the housing part is then combined with the lower side of the outer shell corresponding to the brushless motor, so as to effectively reduce the overall size of this invention.

[0006] To achieve the above objectives and effects, this utility model provides a magnetic portable brushless motor drilling and tapping machine, comprising: a main body, including a housing assembly, a rotating part, a linkage component, a brushless motor, a control module, and a receiving part. The brushless motor is located within the housing assembly, and the linkage component is connected between the rotating part and the brushless motor. The receiving part has a receiving groove and a capacitor groove. The receiving part is disposed on the lower side of the housing assembly corresponding to the brushless motor, with the portion having the capacitor groove. The control module is electrically connected to the brushless motor and is located within the receiving groove. The control module includes at least one capacitor, at least partially located inside the capacitor groove. A lifting component includes a lifting control assembly, which includes a pull rod and a direction change switch. The direction change switch is located at the position corresponding to the pull rod and is electrically connected to the control module. The lifting component is disposed on the main body and connected to the rotating part. A magnetic base is attached to the bottom of the main body at its top.

[0007] Furthermore, the lifting control group of the lifting assembly is provided with a return auxiliary spring on the corresponding side of the steering change switch, and one end of the return auxiliary spring is connected to the pull rod.

[0008] Furthermore, the brushless motor and the control module are electrically connected by a wire, and the outer side of the aforementioned wire has a wire sheath.

[0009] Furthermore, the accommodating portion is configured in an L-shape with the portion having the accommodating groove and the capacitor groove.

[0010] This invention addresses the problems associated with traditional portable drilling and tapping machines using carbon brush motors by replacing them with brushless motors for rotational drive. However, brushless motors have a drawback: they require a control module. Adding a control module significantly increases the overall size of the portable drilling and tapping machine, making it less portable. The control module's large size is due to its bulky capacitor. Therefore, this invention incorporates a capacitor slot within the control module's housing. By attaching this capacitor slot to the underside of the outer casing corresponding to the brushless motor, the overall size of the invention is effectively reduced. In summary, this invention eliminates the need for a carbon brush motor in portable drilling and tapping machines while minimizing the increase in overall size. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0035] like Figures 1 to 4Presented herein, this utility model is a magnetic portable brushless motor drilling and tapping machine, comprising: a main body 1, which includes a housing assembly 11, a rotating part 12, a linkage assembly, a brushless motor 13, a control module 14 (which requires connection to a power source during use), and a receiving part 15. The brushless motor 13 is located within the housing assembly 11, and the linkage assembly is connected between the rotating part 12 and the brushless motor 13. The receiving part 15 has a receiving groove 151 and a capacitor groove 152. The receiving part 15 is positioned on the lower side of the housing assembly 11 corresponding to the brushless motor 13, with the portion having the capacitor groove 152. The control module 14 is electrically connected to the brushless motor 13 and is located within the receiving groove 151. The control module 14 includes at least one capacitor 141, with at least a portion of the capacitor 141 located within the receiving groove 151. Inside the slot 152; a lifting assembly 2, which includes a lifting control group 3, the lifting control group 3 including a pull rod 31 and a steering switch 32, the steering switch 32 being located at the position corresponding to the pull rod 31, the steering switch 32 being electrically connected to the control module 14, the lifting assembly 2 being disposed on the main body 1 and connected to the rotating part 12, in this embodiment the lifting assembly 2 being disposed at the lower front of the main body 1, the lifting assembly 2 being able to drive the rotating part 12 (the end of which may be provided with a tapping blade) to move up and down by means of the lifting control group 3 on its outer side; a magnetic base 4, the top of which is connected to the bottom of the main body 1.

[0036] Continuing from the above description, the embodiments of this utility model are further detailed. To avoid the various problems that arise when using carbon brush motors in traditional portable drilling and tapping machines, this utility model replaces the carbon brush motor 13 with a brushless motor 13 as the rotational driving force. However, the brushless motor 13 has a drawback: it requires a control module 14 for use. Adding the control module 14 to the portable drilling and tapping machine significantly increases its overall size, making it less portable. The reason the control module 14 occupies so much space is due to its large capacitor 141. Therefore, this utility model... Figure 3 As shown, the housing portion 15 of the housing control module 14 is specially designed with a capacitor slot 152 for placing the capacitor 141. By assembling the portion of the housing portion 15 with the capacitor slot 152 onto the lower side of the outer casing 11 corresponding to the brushless motor 13, the overall size of this invention can be effectively reduced. In summary, the structure of this invention truly eliminates the need for a carbon brush motor in portable drilling and tapping machines, effectively reducing internal wear and extending service life. Compared to traditional carbon brush motors, the brushless motor 13 operates more smoothly and efficiently, without generating additional friction noise. Furthermore, this invention, through the special structure of the housing portion 15, minimizes the increase in overall size, demonstrating its innovation.

[0037] And such Figure 4 As this invention utilizes a brushless motor 13 (DC), switching the forward and reverse rotation of the brushless motor 13 actually only requires the use of a single direction switching switch 32, such as... Figure 4 As shown, this state represents the initial position of the rotating part 12. When the user operates the lever 31 of the lifting control group 3 downwards to rotate the entire lifting control group 3, the internal mechanism of the lifting assembly 2 drives the rotating part 12 and the tapping blade to descend (as shown). Figure 7 (as presented), continuing as Figure 5 As shown, lever 31 presses the direction change switch 32 to make the brushless motor 13 rotate in the forward direction, and when the user releases lever 31, it will... Figure 6 As shown, the lever 31 returns to its original position and no longer presses the steering switch 32 (for example, the lifting control group 3 of the lifting assembly 2 is provided with a return auxiliary spring 33 on the side corresponding to the steering switch 32, and one end of the return auxiliary spring 33 is connected to the lever 31. When the user releases the lever 31, the return auxiliary spring 33 causes the lever 31 to return to its initial position). At this time, the rotation direction of the brushless motor 13 returns to the initial reverse direction. As the lifting control group 3 rotates back to its initial position, the rotating part 12 and the tapping blade rise. Compared with the previous carbon brush motor products that required the user to manually switch the motor direction, this utility model is more convenient and easier to operate, and is more practical and convenient.

[0038] Furthermore, the brushless motor 13 and the control module 14 are electrically connected by wires, and the outer side of the aforementioned wires has a wire sheath to provide wire protection.

[0039] Furthermore, the accommodating portion 15 is L-shaped with the accommodating groove 151 and the capacitor groove 152. This structure allows the accommodating portion 15 to fit against the side and bottom of the outer casing 11 corresponding to the position of the brushless motor 13, thereby minimizing the overall size of the present invention and optimizing its portability.

[0040] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
