Description

Technical Field

[0001] This utility model relates to the field of magnetic drill technology, specifically a highly stable magnetic drill. Background Technology

[0002] A magnetic drill works by using an electromagnet in its base to generate a magnetic field after the power is applied. This field attracts the drill bit to the steel workpiece, and the high-speed rotation of the drill motor drives the drill bit to drill holes or thread the steel plate. When drilling holes or threading steel workpieces, different diameter drill bits are required. However, the descent speed of the drill bit cannot be adjusted when the handwheel is turned. This makes it easy for the finer drill bit to break when processing harder steel workpieces. A broken drill bit not only wastes money but also poses a risk of injury.

[0003] To address the aforementioned issues, patent CN202221487890.X discloses a magnetic drill with high stability in its processing stroke, which achieves the effect of preventing the drill bit from breaking due to excessive downward movement speed and improving safety. However, it still has the following problems: the structure is simple, the stability of the magnetic drill motor is not high when adjusting the stroke, and it is prone to uneven force and positional deviation. At the same time, the overall structure is noisy when running, the heat dissipation of the magnetic drill motor is poor, and its use is limited. Therefore, we propose a magnetic drill with high stability to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a highly stable magnetic drill, which solves the problems of existing magnetic drills having simple structures, low stability of the magnetic drill motor during stroke adjustment, easy uneven force causing positional deviation, high noise during operation, poor heat dissipation of the magnetic drill motor, and limited use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a highly stable magnetic drill, comprising a base, a magnetic base body fixedly mounted on the base, a slide rail fixedly mounted on one side of the magnetic base body, an adjusting plate slidably engaged on the slide rail, a motor housing fixedly mounted on the adjusting plate, a top shell fixedly mounted on the top of the motor housing, a first metal filter screen mounted on the front of the motor housing, a second metal filter screen fixedly mounted on the top of the top shell, a motor fixedly mounted inside the motor housing, a rotating shaft mounted on the output end of the motor, a drill bit fixedly mounted on one end of the rotating shaft, a rack plate fixedly mounted on one side of the adjusting plate, a rotating rod rotatably mounted on the magnetic base body via a bearing, a handwheel fixedly mounted on one end of the rotating rod, a gear fixedly mounted on the rotating rod that meshes with the rack plate, a third metal filter screen mounted between the motor housing and the top shell, a fan fixedly mounted inside the top shell, a controller fixedly mounted on the magnetic base body, and a stabilizing component mounted on the adjusting plate below the motor housing.

[0006] Preferably, one side of the adjusting plate is provided with a groove that matches the outer dimensions of the slide rail, and the groove is slidably engaged with the slide rail.

[0007] Preferably, the first metal filter screen penetrates the motor housing, and the second metal filter screen penetrates the top housing.

[0008] Preferably, a limiting plate is fixedly installed on the adjusting plate, and a limiting hole is formed on the limiting plate, through which the rotating shaft is inserted.

[0009] Preferably, the stabilizing component includes a lifting plate slidably mounted on an adjusting plate via two limiting studs, and a wear-resistant stabilizing sleeve is fixedly connected to one side of the lifting plate via a fixing sleeve. The wear-resistant stabilizing sleeve is fitted over the drill bit to stabilize the drill bit, and the lifting plate has an elongated groove adapted to the limiting studs.

[0010] Preferably, the third metal filter is disposed through the housing at the connection between the motor housing and the top housing. Beneficial effects

[0011] This invention provides a highly stable magnetic drill. Compared with the prior art, it has the following advantages:

[0012] 1. This highly stable magnetic drill, by rotating the handwheel, drives the rotating rod to rotate. The gear on the rotating rod meshes with the rack plate on one side of the adjustment plate, driving the adjustment plate to move up and down. This, in turn, drives the motor housing on one side of the adjustment plate to move up and down, thereby adjusting the position of the drill bit mounted on the motor housing. This controls the speed of the drill bit's upward and downward movement, preventing the drill bit from breaking due to excessive downward movement and improving safety. At the same time, the sliding rail on one side of the adjustment plate, which is engaged with the surface of the magnetic base, and the limit plate mounted on the adjustment plate, limit the up and down movement of the adjustment plate and the up and down movement of the drill bit's shaft, respectively. This prevents the force position of the motor and shaft from shifting during the up and down adjustment of the drill bit, improving the stability during adjustment.

[0013] 2. This high-stability magnetic drill comprises a stabilizing component including a lifting plate slidably mounted on an adjusting plate via two limiting studs. A wear-resistant stabilizing sleeve is fixedly connected to one side of the lifting plate via a fixing sleeve. The bottom of the wear-resistant stabilizing sleeve has a notch for chip removal. The wear-resistant stabilizing sleeve is fitted over the drill bit to stabilize it. The lifting plate has a long groove adapted to the limiting studs. By setting the stabilizing component to fit over the drill bit, the drill bit can be restricted, reducing drill bit vibration. Furthermore, its longitudinally sliding design ensures that it will not interfere with the lifting and lowering of the drill bit. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figs. 1-3 This utility model provides two technical solutions: Example

[0020] A highly stable magnetic drill includes a base 1, on which a magnetic base body 2 is fixedly mounted. A slide rail 3 is fixedly mounted on one side of the magnetic base body 2. An adjusting plate 4 is slidably engaged on the slide rail 3. A motor housing 5 is fixedly mounted on the adjusting plate 4. A top shell 6 is fixedly mounted on the top of the motor housing 5. A first metal filter 51 is mounted on the front of the motor housing 5. A second metal filter 61 is fixedly mounted on the top of the top shell 6. A motor 8 is fixedly mounted inside the motor housing 5. A rotating shaft 9 is mounted on the output end of the motor 8. One end of the rotating shaft 9 is fixed... A drill bit 10 is installed. A rack plate 11 is fixedly installed on one side of the adjusting plate 4. A rotating rod 12 is rotatably installed on the magnetic base body 2 via a bearing. A handwheel 13 is fixedly installed at one end of the rotating rod 12. A gear 14 that meshes with the rack plate 11 is fixedly installed on the rotating rod 12. A third metal filter screen 16 is installed between the motor housing 5 and the top housing 6. A fan 17 is fixedly installed inside the top housing 6. A controller 18 is fixedly installed on the magnetic base body 2. A stabilizing component 15 is installed on the adjusting plate 4 and located below the motor housing 5. Example

[0021] The main difference from Example 1 is:

[0022] A highly stable magnetic drill has an adjustment plate 4 with a groove on one side that matches the outer dimensions of a slide rail 3. The groove slides and engages with the slide rail 3, limiting the vertical movement of the adjustment plate 4 to prevent misalignment. A first metal filter 51 penetrates the motor housing 5, and a second metal filter 61 penetrates the top housing 6. The second metal filter 61 is used for air intake inside the top housing 6, and the first metal filter 51 is used for heat dissipation inside the motor housing 5. A limit plate 7 is fixedly installed on the adjustment plate 4, with a limit hole 71. A rotating shaft 9 is inserted through the limit hole 71, limiting the vertical movement of the rotating shaft 9 to prevent misalignment. A third metal filter 16 penetrates the housing at the connection between the motor housing 5 and the top housing 6, providing ventilation between the two and filtering dust from the air entering the motor housing 5 from the top housing 6.

[0023] The stabilizing component 15 includes a lifting plate 151 slidably mounted on the adjusting plate 4 via two limiting studs 154. A wear-resistant stabilizing sleeve 153 is fixedly connected to one side of the lifting plate 151 via a fixing sleeve 152. The wear-resistant stabilizing sleeve 153 has a notch at its bottom for chip removal. The wear-resistant stabilizing sleeve 153 is fitted over the drill bit 10 to stabilize the drill bit 10. The lifting plate 151 has a long groove 155 that matches the limiting studs 154. By setting the stabilizing component 15 to fit over the drill bit 10, the drill bit 10 can be restricted, reducing the vibration of the drill bit 10. Its longitudinally slidable setting ensures that it will not interfere with the lifting and lowering of the drill bit 10.

[0024] In use, rotating the handwheel 13 drives the rotating rod 12 to rotate. The gear 14 on the rotating rod 12 meshes with the rack plate 11 on one side of the adjusting plate 4, causing the adjusting plate 4 to move up and down. This, in turn, moves the motor housing 5 on one side of the adjusting plate 4 up and down, thereby adjusting the position of the drill bit 10 mounted on the motor housing 5. This controls the upward and downward movement speed of the drill bit 10, preventing it from breaking due to excessive downward movement and improving safety. Simultaneously, the sliding rail 3 on one side of the adjusting plate 4, which is slidably engaged with the surface of the magnetic base 2, and the limiting plate 7 mounted on the adjusting plate 4, limit the up and down movement of the adjusting plate 4 and the up and down movement of the rotating shaft 9 at one end of the drill bit 10, respectively. This prevents the force position of the motor 8 and the rotating shaft 9 from shifting during the up and down adjustment of the drill bit 10, improving the adjustment efficiency. The stability of the motor is improved. Furthermore, this invention incorporates a stabilizing component 15 inside the motor housing 5. This component 15 includes a rubber rod 151, a spring damper 152, etc. When the motor 8 is installed inside the motor housing 5 on one side, the softness of the rubber rod 151, the damping characteristics of the spring damper 152, and the energy absorption from the damping friction between the wedge block 153 and the wedge damping block 154 absorb the energy of the shaking. This buffers the shaking during motor 8 operation, reducing noise and preventing disturbance to surrounding personnel. Additionally, a top shell 6 is installed on the motor housing 5, and a fan 17 is installed inside the top shell 6. During motor 8 operation, the fan 17 blows air through the motor housing 5, providing continuous heat dissipation and effectively improving the heat dissipation of the motor 8, thus maintaining its stable and long-term operation.
