Description

Technical Field

[0001] The present application relates to the field of drill bits, and more particularly, to a fixing structure and a drill bit. Background Art

[0002] A drill bit is a tool that rotates and has a cutting ability at the tip, mainly used for drilling holes in metals or other materials. It uses the rotation generated by an electric motor as power and is operated by a person or a machine to drill holes in different materials. When a drill press is in use, the rotation of the drill bit is usually the main movement, and the axial movement of the drill bit is the feed movement. The drill press has a simple structure and relatively low machining accuracy. It can drill through holes and blind holes, and by replacing special tools, it can perform operations such as reaming, counterboring, boring, or tapping. During the machining process, the workpiece remains stationary while the tool moves. The tool center is aligned with the hole center, and the tool rotates (main movement). The characteristic of the drill press is that the workpiece is fixed and the tool rotates.

[0003] Currently, when a drill press drill bit is in use, the drill bit is fixed to the mounting seat by bolts. When disassembling and assembling the drill bit, external tools are required, which reduces the work efficiency and the practicality of the device. Summary of the Utility Model

[0004] To make up for the above deficiencies, the present application provides a fixing structure and a drill bit, aiming to improve the problem that when a current drill press drill bit is in use, the drill bit is fixed to the mounting seat by bolts, and external tools are required when disassembling and assembling the drill bit, thereby reducing the work efficiency and the practicality of the device.

[0005] In a first aspect, an embodiment of the present application provides a fixing structure, including a drill bit body and a mounting structure. The drill bit body includes a drill bit main body and a fixing plate. The fixing plate is disposed on one side of the drill bit main body. The mounting structure includes a mounting frame, a bidirectional lead screw, two lead screw nut pairs, a clamping frame, a handle, and a clamping component. The bidirectional lead screw is rotatably connected to the mounting frame. The two lead screw nut pairs are connected to the bidirectional lead screw. The clamping frame is connected to the lead screw nut pairs. The fixing plate is in contact with the inner wall of the clamping frame. The handle is connected to the bidirectional lead screw. The clamping component is disposed in the handle and is clamped to the mounting frame.

[0006] In a specific implementation, the clamping component includes a sliding rod, a sliding block, and a spring. The sliding rod is slidably connected to the handle and is clamped to the mounting frame. The sliding block is connected to the sliding rod and is slidably connected to the handle. The spring is sleeved on the sliding rod.

[0007] In the above implementation process, through the setting of the sliding rod, the sliding block, and the spring, it is possible to conveniently fix the position of the handle and prevent the bidirectional lead screw from rotating when the drill bit is in use.

[0008] In a specific embodiment, a pulling block is provided at one end of the sliding rod.

[0009] In the above implementation process, by providing a pulling block at one end of the sliding rod, it is convenient for the user to pull the sliding rod, saving time and effort.

[0010] In a specific embodiment, a clamping groove is provided on one side of the mounting frame, and the sliding rod is clamped with the clamping groove.

[0011] In the above implementation process, by clamping the sliding rod with the clamping groove, the connection between the sliding rod and the mounting frame can be facilitated.

[0012] In a specific embodiment, a limiting block is provided on one side of each of the two lead screw nut pairs, a sliding groove is provided on the inner wall of the mounting frame, and the limiting block is slidably connected with the sliding groove.

[0013] In the above implementation process, by slidably connecting the limiting block with the sliding groove, the movement of the lead screw nut pair can be conveniently limited.

[0014] In a specific embodiment, bearings are embedded on both sides of the mounting frame, and the bidirectional lead screw is in interference fit with the inner ring of the bearing.

[0015] In the above implementation process, by the interference fit between the bidirectional lead screw and the inner ring of the bearing, the rotational connection between the bidirectional lead screw and the mounting frame can be facilitated.

[0016] In a specific embodiment, the mounting frame is provided with a through mounting hole.

[0017] In the above implementation process, by providing a through mounting hole in the mounting frame, the connection between the mounting frame and an external drill can be facilitated.

[0018] In a second aspect, the present utility model further provides a drill bit, including the above-mentioned fixing structure.

[0019] Compared with the prior art, the beneficial effects of the present application are as follows: through the setting of the clamping assembly, the position of the handle can be conveniently fixed, preventing the bidirectional lead screw from rotating during the use of the drill bit. By rotating the handle to drive the bidirectional lead screw to rotate, the two lead screw nut pairs and the clamping frame move away from each other, facilitating the disassembly of the drill bit body and the fixing plate, and improving the work efficiency.

[0033] When specifically arranged, the clamping component 260 includes a sliding rod 261, a sliding block 262 and a spring 263. The sliding rod 261 is slidably connected to the handle 250. The sliding rod 261 is clamped to the installation frame 210. The sliding block 262 is connected to the sliding rod 261. The sliding block 262 is slidably connected to the handle 250. The spring 263 is sleeved on the sliding rod 261. Among them, through the arrangement of the sliding rod 261, the sliding block 262 and the spring 263, it is convenient to fix the position of the handle 250 and prevent the bidirectional lead screw 220 from rotating when the drill bit is in use.

[0035] When specifically arranged, a clamping groove is formed on one side of the installation frame 210. The sliding rod 261 is clamped to the clamping groove. Among them, through the clamping connection between the sliding rod 261 and the clamping groove, it is convenient for the connection between the sliding rod 261 and the installation frame 210.

[0036] When specifically arranged, a limiting block 270 is arranged on one side of each of the two lead screw nut pairs 230.

[0039] The present utility model further provides a drill bit, which includes the above-mentioned fixing structure.

[0040] The working principle of the fixing structure and the drill bit: When using the fixing structure and the drill bit, pulling the sliding rod 261 drives the slider 262 to move, and compresses the spring 263, so that the sliding rod 261 is disengaged from the clamping connection with the mounting frame 210. At this time, turning the handle 250 drives the bidirectional lead screw 220 to rotate, so that the two lead screw nut pairs 230 and the clamping frame 240 move away from each other, facilitating the disassembly of the drill bit body 110 and the fixing plate 120, and improving the working efficiency.

[0041] It should be noted that the specific model and specification of the drill bit body 110 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail here.

[0042] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
