Description

Technical Field

[0001] This utility model relates to the technical field of cutting tools, specifically a composite coated PCB cutting tool. Background Technology

[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. The vast majority of cutting tools are machine-made, but some are hand-made.

[0003] For example, a composite coated PCB cutting tool with authorization announcement number "CN220073375U" solves the problem of cleaning debris and dust adhering to the coating of existing composite coated PCB cutting tools. The aforementioned tool can clean debris and dust adhering to the surface of the composite coated component when needed through airflow, thereby reducing the difficulty of cleaning. However, considering that the cutting tools in existing composite coated PCB cutting tools are used with a single cutting head, it is necessary to disassemble and replace the cutting head to match other composite coated PCB cutting tools with different threads. At the same time, it is necessary to find the place of the cutting head and reinstall it according to the disassembly method, which makes it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing composite coated PCB cutting tools require disassembly and reassembly for use with a single cutting head, which is inconvenient. Therefore, this invention proposes a composite coated PCB cutting tool.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite coated PCB cutting tool, comprising a shank and a cutting edge, wherein the inner wall of the upper end of the shank is machined with a threaded hole, the outer wall of the middle part of the shank is fixedly connected to a threaded sleeve, the outer wall of the shank is movably connected to an internal threaded ring, the inner wall of the internal threaded ring is slidably connected to a square block, and a deflection mechanism is connected to the end of the shank.

[0006] Preferably, the deflection mechanism includes a connector, the outer wall of which is rotatably connected to the handle, the end of which is fixedly connected to a circular seat, the outer wall of which is threadedly connected to a sleeve, and the outer wall of which is machined with a square groove.

[0007] Preferably, the outer wall of the circular seat is fixedly connected to the blade, the surface of the blade is coated with a composite coating, and the inner wall of the handle is connected to a limit mechanism.

[0008] Preferably, the limiting mechanism includes a slider, the outer wall of the slider is slidably connected to a groove machined on the handle, the outer wall of the slider is fixedly connected to a square seat, and the lower end of the square seat is fixedly connected to a square column.

[0009] Preferably, the limiting mechanism includes a slider, the outer wall of the slider is slidably connected to a groove machined on the handle, the outer wall of the slider is fixedly connected to a square seat, and the lower end of the square seat is fixedly connected to a square column.

[0010] Preferably, the outer wall of the square column abuts against the square groove.

[0011] The composite coated PCB cutting tool proposed in this utility model has the following advantages: by manually turning the connector, the lower end of the shank will rotate, so that the different functional cutting edges at the end of the connector are perpendicular to the shank. Tightening the internal threaded ring will put it into the threaded sleeve, so that the square block on the internal threaded ring is pressed against the upper end of the square seat. The square post at the lower end of the square seat will be inserted into the square groove on the outside of the connector, thus realizing the connection and fixation between the connector and the shank. Different cutting heads can be replaced for use without disassembly and reinstallation, which is inconvenient to use. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] Please see Figure 1-6In this embodiment, a composite coated PCB cutting tool includes a shank 1 and a cutting edge 2. The inner wall of the upper end of the shank 1 is machined with a threaded hole 3. The outer wall of the middle part of the shank 1 is fixedly connected to a threaded sleeve 4. The outer wall of the shank 1 is movably connected to an inner threaded ring 5. The inner wall of the inner threaded ring 5 is slidably connected to a square block 6. The end of the shank 1 is connected to a deflection mechanism 7.

[0022] The deflection mechanism 7 includes a connector 701. By manually turning the connector 701, it will rotate at the lower end of the handle 1, thereby realizing the deflection movement of the blade 2 with different functions at the end of the connector 701 and the handle 1. The outer wall of the connector 701 is rotatably connected to the handle 1. The end of the connector 701 is fixedly connected to the circular seat 702. The outer wall of the circular seat 702 is threadedly connected to the sleeve 703. The outer wall of the connector 701 is machined with a square groove 704.

[0023] The outer wall of the circular seat 702 is fixedly connected to the cutting edge 2. The surface of the cutting edge 2 is processed with a composite coating 8. The composite coating 8 is a spraying technology including titanium nitride coating or diamond carbon coating, which can improve the surface hardness and insulation of the cutting edge 2. The inner wall of the handle 1 is connected to a limiting mechanism 9. The limiting mechanism 9 includes a slider 901. The outer wall of the slider 901 is slidably connected to the groove processed on the handle 1. The outer wall of the slider 901 is fixedly connected to the square seat 902. The lower end of the square seat 902 is fixedly connected to the square post 903.

[0024] Manually turning the connector 701 will rotate the lower end of the shank 1, so that the different functional cutting edges 2 at the end of the connector 701 are perpendicular to the shank 1. Tightening the internal threaded ring 5 will put it into the threaded sleeve 4, so that the square block 6 on the internal threaded ring 5 is pressed against the upper end of the square seat 902. The square post 903 at the lower end of the square seat 902 will be inserted into the square groove 704 on the outside of the connector 701, thus achieving the function of connecting and fixing the connector 701 and the shank 1. Different cutting heads can be replaced and used without disassembling and reinstalling, which is convenient to use.

[0025] The limiting mechanism 9 includes a slider 901, which enters the threaded sleeve 4 through the internal threaded ring 5. The square post 903 at the lower end of the square seat 902 is inserted into the square groove 704 outside the connector 701, so that the square post 903 can limit the connector 701. The outer wall of the slider 901 is slidably connected to the groove processed in the handle 1. The outer wall of the slider 901 is fixedly connected to the square seat 902. The lower end of the square seat 902 is fixedly connected to the square post 903. The outer wall of the square post 903 abuts against the square groove 704.

[0026] Working principle:

[0027] When the cutting tool is needed, it is installed on the machine tool holder using the threaded hole 3 on the shank 1. Then, the cutting edge 2 is driven by the machine tool to perform cutting operations. The composite coating component 8 on the surface of the cutting edge 2 enhances hardness and insulation. When the cutting edge 2 needs to be switched, the internal threaded ring 5 is manually turned to disengage from the threaded sleeve 4 on the shank 1. The internal threaded ring 5 and the square seat 902 are then manually pushed to move the square block 6 on the internal threaded ring 5 to the top of the shank 1 and the square post 903 on the square seat 902 to the top of the shank 1. Turning the connector 701 will rotate the lower end of the shank 1, allowing the different functional cutting edges at the end of the connector 701 to rotate. The blade 2 is perpendicular to the handle 1. Tightening the sleeve 703 disengages it from the thread on the circular seat 702, exposing the vertically positioned blade 2 for use. Similarly, push the internal threaded ring 5 and the square seat 902 again, moving the square block 6 on the internal threaded ring 5 to the bottom of the handle 1, and the square post 903 on the square seat 902 to the bottom of the handle 1. Tighten the internal threaded ring 5 into the threaded sleeve 4, causing the square block 6 on the internal threaded ring 5 to press against the upper end of the square seat 902. The square post 903 at the lower end of the square seat 902 will insert into the square groove 704 outside the connector 701, thus fixing the connector 701 to the handle 1. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
