Description

Technical Field

[0001] This utility model relates to the field of electric drill assembly technology, and in particular to an electric drill assembly with auxiliary devices. Background Technology

[0002] An electric drill is a handheld power tool that uses electrical energy to drive the drill bit to rotate, thereby drilling holes in various materials. Its basic principle is that the motor converts electrical energy into mechanical energy. The rotation of the motor is transmitted to the chuck through a transmission device such as gears. The chuck clamps the drill bit and drives it to rotate. When the drill bit is pressed against the surface of the material and a certain pressure is applied, the rotating drill bit can cut into the material and drill a hole.

[0003] Currently, hand tremors are inevitable when workers hold electric drills. When drilling on smooth surfaces, it is difficult to quickly position and maintain the drilling position. When pressure is applied, the drilling position of the drill bit is easily deviated, which affects the verticality and diameter accuracy of the hole. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art where workers inevitably experience hand tremors when using a handheld electric drill, making it difficult to quickly position and maintain the drilling position when drilling on smooth surfaces, and causing the drill bit to shift when pressure is applied, thus affecting the verticality and diameter accuracy of the drill hole. Therefore, this invention proposes an electric drill assembly with an auxiliary device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electric drill assembly with an auxiliary device, including a fixed base, a dust cover fitted on the outside of the fixed base, anti-slip feet fixedly connected to the outer wall of the fixed base, three anti-slip feet arranged in an equidistant circular array on the outer wall of the fixed base, a laser emitting module embedded in the lower outer wall of the anti-slip feet, a battery installed on one side of the outer wall of the fixed base, the battery being electrically connected to the laser emitting module, a telescopic groove penetrating through the center of the top surface of the fixed base, a guide sleeve movably connected to the inner wall of the telescopic groove, a guide through hole penetrating through the center of the top surface of the guide sleeve, and an anti-slip pad fixedly connected to the upper inner wall of the guide through hole.

[0006] Preferably, the outer wall of the anti-slip support foot is provided with a connecting groove, and a magnetic suction plate is fixedly connected to the outer wall of the connecting groove.

[0007] Preferably, a magnetic ring is fixedly connected to the top of the dust cover, and the magnetic ring is magnetically connected to the magnetic plate.

[0008] Preferably, a pressure plate is provided inside the telescopic groove, and a bearing is fixedly connected to the inner wall of the pressure plate, with the inner ring of the bearing sleeved on the lower outer wall of the guide sleeve.

[0009] Preferably, a guide plate is fixedly connected to the inner wall of the telescopic groove, and a limiting groove is formed through the top surface of the pressure plate, with the inner wall of the limiting groove being movably connected to the outer wall of the guide plate.

[0010] Preferably, a spring is provided below the pressure plate, and the spring is sleeved on the outer wall of the guide sleeve.

[0011] Preferably, one end of the spring is fixedly connected to the bottom surface of the telescopic groove, and the other end of the spring is fixedly connected to the bottom surface of the pressure plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, laser lines are emitted by the laser emitting modules of three anti-slip feet and projected onto the surface of the drill hole. The center positioning of this utility model is achieved by using the intersection point of the three sets of laser lines. Then, the drill bit is inserted into the guide hole by hand-held electric drill to quickly position the drill hole. The rotation of the guide sleeve is used to limit and guide the rotation and downward pressure of the drill bit, thereby avoiding positional deviation and vibration when the electric drill is drilling, thus effectively improving the verticality and diameter accuracy of the drill hole.

[0014] 2. In this utility model, by setting up a dust cover, the dust cover is magnetically connected to the magnetic plate by the magnetic ring during drilling, thereby fixing the dust cover on the outside of the anti-slip support and the fixed base to achieve shielding and protection, effectively preventing the flying of debris and dust generated during drilling.

There are three anti-slip feet 3, which are equidistantly arranged in a circular array on the outer wall of the fixed base 1. A laser emitting module 33 is embedded in the lower outer wall of the anti-slip feet 3. A battery 5 is installed on one side of the outer wall of the fixed base 1. The battery 5 is electrically connected to the laser emitting module 33. A telescopic groove 11 is opened through the center of the top surface of the fixed base 1. A guide sleeve 4 is movably connected to the inner wall of the telescopic groove 11. A guide through hole 42 is opened through the center of the top surface of the guide sleeve 4. An anti-slip pad 41 is fixedly connected to the upper inner wall of the guide through hole 42.

[0023] The specific settings and functions of this embodiment are described below. Laser lines are emitted by the laser emitting modules 33 of the three anti-slip feet 3 and projected onto the drilling surface. The center positioning of this utility model is achieved by using the intersection point of the three sets of laser lines. Then, the drill bit is inserted into the guide through hole 42 by hand-held electric drill to quickly position the drilling position. The rotation of the guide sleeve 4 is used to limit and guide the rotation and downward pressure of the drill bit, thereby avoiding positional deviation and vibration when the electric drill is drilling, thus effectively improving the verticality and diameter accuracy of the drilling.

[0024] Example 2: Figure 1 - Figure 4As shown, the outer wall of the anti-slip support foot 3 is provided with a connecting groove 31, and a magnetic suction plate 32 is fixedly connected to the outer wall of the connecting groove 31. A magnetic suction ring 21 is fixedly connected to the top of the dust cover 2. The magnetic suction ring 21 and the magnetic suction plate 32 are magnetically connected. A pressure plate 13 is provided inside the telescopic groove 11. A bearing 16 is fixedly connected to the inner wall of the pressure plate 13.

A spring 15 is provided below the pressure plate 13. The spring 15 is sleeved on the outer wall of the guide sleeve 4. One end of the spring 15 is fixedly connected to the inner bottom surface of the telescopic groove 11, and the other end of the spring 15 is fixedly connected to the bottom surface of the pressure plate 13.

[0025] The overall effect of this embodiment is that the sliding connection between the pressure plate 13 and the guide plate 12 guides the downward movement of the guide sleeve 4 in the telescopic groove 11, improving drilling accuracy. The dust cover 2 allows the present invention to magnetically connect the magnetic ring 21 and the magnetic plate 32 during drilling, thereby fixing the dust cover 2 on the outside of the anti-slip support 3 and the fixed base 1 to achieve shielding and protection, effectively preventing the flying of debris and dust generated during drilling. The spring 15 allows the guide sleeve 4 to return to its original position after the downward pressing is completed, making it easy to remove the drill bit.

[0026] The usage method and working principle of this device are as follows: During use, the user projects laser lines onto the drilling surface through the laser emitting modules 33 of the three anti-slip feet 3. The center positioning of this utility model is achieved by using the intersection point of the three sets of laser lines. Then, the user holds an electric drill and inserts the drill bit into the guide through hole 42 to quickly position the drilling position. The rotation of the guide sleeve 4 limits and guides the rotation and downward pressure of the drill bit. The sliding connection between the pressure plate 13 and the guide plate 12 guides the downward movement of the guide sleeve 4 in the telescopic groove 11, improving the drilling accuracy. The dust cover 2 allows the utility model to be magnetically connected to the magnetic plate 32 using the magnetic ring 21 during drilling, thereby fixing the dust cover 2 on the outside of the anti-slip feet 3 and the fixed base 1 for shielding and protection.
