Description

Technical Field

[0001] This utility model relates to the field of auger drill technology, specifically an auger drill that can be quickly clamped. Background Technology

[0002] A auger drill is a commonly used tool in machining and engineering geological drilling, typically used for drilling holes or drilling into soft formations. It consists of two parts: a drill rod and a drill bit. The drill bit has helical cutting edges that, through rotation, cut material into a circular hole or cut through a layer of soil. The structure of an auger may include a cutting edge, a center cone, a core rod, and a shank, with the cutting edge being the most important part, usually composed of multiple concentric cutting teeth.

[0003] A woodworking auger with Chinese patent number CN216067877U, which can be quickly clamped, includes an installation chamber. A connecting seat is movably installed inside the installation chamber, and a drill bit is fixedly connected to the top of the connecting seat. An assembly mechanism is provided inside the installation chamber. The assembly mechanism includes stabilizing components arranged on the left and right sides of the connecting seat. With the assembly mechanism, the drill bit can be quickly assembled with simple operation.

[0004] Although the aforementioned document describes a auger drill bit that can be quickly assembled, the spring-clamped mounting of the auger drill bit on the connecting seat can easily cause the spring to deform under working force, leading to unstable installation of the auger drill bit and affecting the stability of the drill bit installation. Therefore, it is necessary to propose an auger drill bit that can be quickly clamped to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a spiral drill that can be quickly clamped, which allows for rapid installation of the drill bit while achieving stable installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spiral drill that can be quickly clamped, comprising a mounting chamber and a connecting seat disposed within the mounting chamber. A connecting plate extending to the outside of the mounting chamber is fixedly connected to the lower end face of the connecting seat. A drill bit is mounted on the lower end face of the connecting plate. A positive and negative lead screw is rotatably connected inside the mounting chamber. A motor with its output end fixedly connected to the positive and negative lead screw is mounted on the left side of the inner wall of the mounting chamber. Mounting plates are threaded to both ends of the outer wall of the positive and negative lead screw. Mounting grooves matching the mounting plates are opened on both the left and right sides of the outer wall of the connecting seat.

[0007] A fixed frame is installed at the top of the inner wall of the installation chamber. A limit post is fixedly connected to the lower end of the fixed frame. A limit groove matching the limit post is opened on the upper end of the connecting seat. A first electromagnetic plate that can attract each other is installed between the bottom of the inner wall of the limit groove and the limit post.

[0008] In order to achieve the installation and fixation of the connecting plate, as a preferred embodiment of the spiral drill of this utility model that can be quickly clamped, the left and right sides of the inner wall of the installation chamber are provided with positioning grooves that abut against the connecting plate. The interior of each of the two positioning grooves is connected to the left and right sides of the upper surface of the connecting plate through a horizontal plate and a second electromagnetic plate that can attract each other.

[0009] For positioning and installing the connecting plate, as a preferred embodiment of this utility model of a spiral drill that can be quickly clamped, the inner wall of the part of the connecting plate located outside the installation chamber is fixedly connected to a positioning block located at the bottom of the installation chamber.

[0010] In order to limit the position of the mounting plate, as a preferred embodiment of the spiral drill of this utility model that can be quickly clamped, the top of the mounting chamber is fixedly connected to a slide rod that is slidably connected to the mounting plate.

[0011] For internal maintenance of the installation chamber, as a preferred embodiment of this utility model of a auger drill that can be quickly clamped, the outer wall of the installation chamber is bolted with a sealing cover.

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

[0013] This invention first pushes the connecting seat into the installation chamber. The first electromagnetic plates attract each other to fix the limiting post inside the limiting groove. Then, the two mounting plates are brought close to each other and enter the installation groove to limit and fix the connecting seat. Thus, the drill bit can be quickly installed through the mounting plates, the installation groove, the limiting post, the limiting groove, and the first electromagnetic plate, while achieving a stable installation effect.

A drill bit 1 is mounted on the lower end face of the connecting plate 101. A positive and negative lead screw 301 is rotatably connected inside the mounting chamber 3. A motor 302 whose output end is fixedly connected to the positive and negative lead screw 301 is mounted on the left side of the inner wall of the mounting chamber 3. Both ends of the outer wall of the positive and negative lead screw 301 are threadedly connected to mounting plates 304. Mounting grooves 201 matching the mounting plates 304 are opened on both the left and right sides of the outer wall of the connecting seat 2.

[0019] A fixed frame 4 is installed at the top of the inner wall of the installation chamber 3. A limit post 401 is fixedly connected to the lower end of the fixed frame 4. A limit groove 202 matching the limit post 401 is opened on the upper end of the connecting seat 2. A first electromagnetic plate 203 that can attract each other is installed between the bottom of the inner wall of the limit groove 202 and the limit post 401.

[0020] In this embodiment: the connecting seat 2 is pushed into the mounting chamber 3 until the limiting post 401 enters the limiting groove 202. At the same time, the first electromagnetic plate 203 attracts each other, fixing the limiting post 401 inside the limiting groove 202, so that the limiting post 401 and the limiting groove 202 are stably connected. Then, the motor 302 can be started, causing the motor 302 to drive the positive and negative lead screws 301 to rotate, causing the two mounting plates 304 to move closer to each other until the two mounting plates 304 enter the mounting groove 201, limiting and fixing the connecting seat 2. Thus, the drill bit 1 can be quickly installed and stably installed through the mounting plates 304, the mounting groove 201, the limiting post 401, the limiting groove 202, and the first electromagnetic plate 203.

[0021] As a technical optimization of this utility model, positioning grooves 402 that abut against the connecting plate 101 are provided on both the left and right sides of the inner wall of the installation chamber 3. The interior of the two positioning grooves 402 is connected to the left and right sides of the upper surface of the connecting plate 101 by a horizontal plate and a second electromagnetic plate 403 that can attract each other.

[0022] In this embodiment: the connecting plate 101 is aligned with the positioning groove 402 and installed, and the connecting plate 101 is pushed into the installation chamber 3 until the connecting plate 101 abuts against the horizontal plate. The connecting plate 101 and the horizontal plate are attracted and fixed to each other by the second electromagnetic plate 403, thereby realizing the installation and fixing of the connecting plate 101.

[0023] As a technical optimization of this utility model, a positioning block located at the bottom of the installation chamber 3 is fixedly connected to the inner wall of the connecting plate 101 located outside the installation chamber 3.

[0024] In this embodiment, the connecting plate 101 can be positioned and installed using a positioning block.

[0025] As a technical optimization of this utility model, a slide rod 303 is fixedly connected to the top of the installation compartment 3 and is slidably connected to the installation plate 304.

[0026] In this embodiment, the mounting plate 304 can be limited by the slide bar 303 to prevent the mounting plate 304 from rotating with the positive and negative lead screws 301.

[0027] As a technical optimization of this utility model, the outer wall of the installation chamber 3 is connected to a sealing cover by bolts.

[0028] In this embodiment, opening the sealing cover facilitates internal maintenance of the installation chamber 3.

[0029] Working principle: First, the battery in the battery box inside the mounting chamber 3 provides power to the motor 302, the first electromagnetic plate 203, and the second electromagnetic plate 403. The connecting plate 101 is aligned with the positioning groove 402 and pushed into the mounting chamber 3 until it abuts against the horizontal plate. The second electromagnetic plate 403 then attracts and fixes the connecting plate 101 and the horizontal plate together. Simultaneously, the connecting seat 2 enters the mounting chamber 3, and the limiting post 401 enters the limiting groove 202. The first electromagnetic plate 203 attracts and fixes the motor 302, the first electromagnetic plate 403, and the second electromagnetic plate 403 then engages with the motor. The limiting post 401 is attracted and fixed inside the limiting groove 202, so that the limiting post 401 and the limiting groove 202 are stably connected. Then the motor 302 can be started, so that the motor 302 drives the positive and negative lead screws 301 to rotate, causing the two mounting plates 304 to move closer to each other until the two mounting plates 304 enter the mounting groove 201, limiting and fixing the connecting seat 2. Thus, the drill bit 1 can be quickly installed through the mounting plates 304, the mounting groove 201, the limiting post 401, the limiting groove 202 and the first electromagnetic plate 203, while achieving a stable installation effect.
