Description

Technical Field

[0001] This utility model relates to the field of electric drill technology, and in particular to a single-drive silent drill. Background Technology

[0002] A silent drill is a drilling tool designed to reduce noise. It uses various technologies to lower the noise level generated during drilling, making it more user-friendly in homes, offices, or noise-sensitive environments. Silent drills are typically used in situations requiring quiet operation, such as nighttime construction, residential areas, hospitals, and schools.

[0003] Existing silent drills require aligning the drill bit with the desired drilling location, holding the machine, and driving the drill bit deeper to complete the drilling process. The special structure of the drill bit is designed to reduce noise during drilling.

[0004] Existing silent drills require the handheld unit to move the drill bit deeper to complete the drilling process. The debris generated during drilling can easily cause workers to be cut. The drill bit cannot be used independently for drilling, making it inconvenient to use. Utility Model Content

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This is the first embodiment of the present invention. This embodiment provides a single-drive silent drill, including a mobile housing 1, a fixed housing 7 disposed below the mobile housing 1, a propulsion component 5 disposed inside the fixed housing 7, a drive component 2 disposed inside the mobile housing 1, a drill bit 3 inserted inside the mobile housing 1, a support plate 6 fixedly connected to the lower surface of the fixed housing 7, the propulsion component 5 including a limiting plate 509 fixedly connected to the upper surface of the fixed housing 7, a connecting plate 510 fixedly connected to the top of the limiting plate 509, a threaded rod 502 movably connected between the connecting plate 510 and the fixed housing 7 through a bearing seat, a threaded sleeve 504 threadedly connected to the outer surface of the threaded rod 502, a connecting block 503 fixedly connected to the outer surface of the threaded sleeve 504, the side of the connecting block 503 away from the threaded sleeve 504 fixedly connected to the outer surface of the mobile housing 1, and a grip handle 507 fixedly connected to both sides of the mobile housing 1.

[0031] Specifically, a servo motor 501 is fixedly connected to the upper surface of the fixed housing 7. A transmission gear 506 is fixedly connected to the output end of the servo motor 501. A driven gear 505 is meshed with the outer surface of the transmission gear 506. The interior of the driven gear 505 is fixedly connected to the outer surface of the threaded rod 502. A power supply box 4 is fixedly connected to the upper surface of the connecting plate 510. A battery for powering the reduction motor 201 and the servo motor 501 is installed inside the power supply box 4. A control module is installed inside the power supply box 4. A sliding block 508 is fixedly connected to the side of the movable housing 1 near the connecting block 503. The sliding block 508 is slidably connected to the outer surface of the limit plate 509.

[0032] Furthermore, the servo motor 501 drives the driven gear 505 to rotate via the transmission gear 506. The driven gear 505 drives the threaded rod 502 to rotate, thereby causing the threaded sleeve 504 to move on the outer surface of the threaded rod 502. The threaded sleeve 504 drives the moving housing 1 to move via the connecting block 503. During the movement of the moving housing 1, the sliding block 508 and the limiting plate 509 cooperate to achieve limiting. Finally, the movement of the moving housing 1 drives the drill bit 3 to descend. The servo motor 501 is controlled to rotate via the control module, thereby controlling the depth of descent of the drill bit 3. The connection relationship, working principle and operation sequence between the control module, power supply and other components are existing technologies and are common knowledge known to those skilled in the art, and will not be elaborated further here.

[0033] Example 2

[0034] Reference Figure 1 and Figure 6This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The drive component 2 includes a connecting cylinder 204 that is movably connected to the inside of the mobile housing 1 via a bearing. The drill bit 3 is disposed inside the connecting cylinder 204. A rotating gear 203 is fixedly connected to the outer surface of the connecting cylinder 204.

[0035] Specifically, a geared motor 201 is fixedly connected to the upper surface of the mobile housing 1. The output end of the geared motor 201 passes through the upper surface of the mobile housing 1 and is movably connected to the bottom of the inner cavity of the mobile housing 1 through a bearing. A drive gear 202 is fixedly connected to the output end of the geared motor 201. The drive gear 202 meshes with the rotating gear 203. When the threaded sleeve 504 is located at the highest point of the thread on the outer surface of the threaded rod 502, the bottom end of the drill bit 3 is higher than the upper surface of the support plate 6.

[0036] Furthermore, the starting geared motor 201 drives the rotating gear 203 to rotate through the drive gear 202, thereby driving the drill bit 3 to rotate through the connecting sleeve 204. When the threaded sleeve 504 is at the highest point of the thread position on the outer surface of the threaded rod 502, the bottom end of the drill bit 3 is higher than the upper surface of the support plate 6, thereby preventing the drill bit 3 from protruding when the support plate 6 is placed on the plane where drilling is required, which would cause it to be unable to be placed stably. Moreover, the support of the support plate 6 ensures that the drill bit 3 is perpendicular to the drilling plane.

[0037] Working principle: When using the single-drive silent drill, place the support plate 6 on the area to be drilled, then start the reduction motor 201. The reduction motor 201 drives the rotating gear 203 to rotate via the drive gear 202, which in turn drives the drill bit 3 to rotate via the connecting cylinder 204. Then, start the servo motor 501. The servo motor 501 drives the driven gear 505 to rotate via the transmission gear 506. The driven gear 505 drives the threaded rod 502 to rotate, which in turn drives the threaded sleeve 504 to rotate on the outer surface of the threaded rod 502. The threaded sleeve 504 moves, driving the moving housing 1 via the connecting block 503. During the movement of the moving housing 1, the sliding block 508 and the limiting plate 509 cooperate to achieve limiting. Ultimately, the movement of the moving housing 1 drives the drill bit 3 to descend, thereby achieving drilling treatment at the drilling location. The drill bit 3 is driven by a single geared motor 201, while the movement of the drill bit 3 is driven by the servo motor 501 to deepen the hole. This eliminates the need for manual control by the worker, preventing drill debris from causing injury to the worker.
