[0002] A CNC engraving and milling machine tool is a type of precision machining tool used on a CNC engraving and milling machine to perform precision machining on workpieces in order to obtain a high-precision, high-smooth workpiece surface.

[0003] In the current technology, most engraving and milling cutters are fixed by threaded installation or snap-fit. After a certain period of use, the cutter may become loose or unstable due to vibration, resulting in deviations in the engraved mold and failing to achieve high precision. The main reason for this is the instability of the cutter. Therefore, this problem needs to be further solved and improved. Utility Model Content

[0004] The purpose of this utility model is to provide a high-precision engraving and milling tool that solves the problem that after a certain period of use, the tool may become loose or unstable due to vibration, resulting in deviations in the engraved and milled molds and failing to achieve high-precision results.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-4 This utility model provides a high-precision engraving and milling tool, comprising: a tool body 1, with a mounting post 9 fixedly connected to the middle of the top end of the tool body 1. During its ascent, the mounting post 9 abuts against a pin 8. Because the end of the pin 8 is arc-shaped, it provides an expanding abutment. A mounting sleeve 3 is inserted into the outside of the mounting post 9. Installation is performed by inserting the top end of the tool body 1 into the mounting sleeve 3. A mating sleeve 6 is fixedly connected to the middle of the mounting sleeve 3. A flange 5 is fixedly connected to the top of the cylinder 3. The flange 5 is connected to the drive device to complete the high-speed rotation of the tool body 1. The engraving and milling work is realized through the cutter head 2. Fixed sleeves 17 are fixedly connected to both sides of the sleeve 6. A pin 8 is inserted into the inside of the fixed sleeve 17. The locking of the pin 8 and the through hole 10 can prevent loosening and instability, thereby achieving a high-precision and high-stability operating state. A through hole 10 is opened in the middle of the top of the mounting column 9. The pin 8 and the through hole 10 are inserted and matched.

[0020] A retaining ring 16 is fixedly connected to the center of the mounting sleeve 3. Both the retaining ring 16 and the top of the tool body 1 have pin slots 14 on both sides. A buffer spring 12 is fixedly connected inside one pin slot 14, and an arc-shaped pin block 13 is fixedly connected to the top of the buffer spring 12. When the pin slot 14 and the arc-shaped pin block 13 are engaged, the through hole 10 will be in the horizontal insertion position corresponding to the pin rod 8. Due to the elastic support of the support spring 7, the pin rod 8 can be inserted and locked into the through hole 10. The arc-shaped pin block 13 engages with the pin slot 14 and the bottom wall of the retaining ring 16 in the center of the mounting sleeve 3. At this time, the arc-shaped pin block 13 on the bottom wall of the retaining ring 16 engages with the pin slot 14. The arc-shaped pin block 13 and the pin slot 14 are engaged. The top of the arc-shaped pin block 13 and the pin slot 14 are engaged. 4. The outer edges are all arc-shaped. An external thread 11 is provided on the upper middle part of the tool body 1. The external thread 11 is threaded with the inner wall of the bottom end of the mounting sleeve 3 to complete the threaded upward action. An internal thread 15 is provided on the bottom end of the inner wall of the mounting sleeve 3. The internal thread 15 and the external thread 11 are threaded together. A support spring 7 is fixedly connected to one end of the fixed sleeve 17. The support spring 7 is fixedly connected to the pin rod 8. A pull rod 4 is provided inside the support spring 7. Pulling the pull rod 4 outward will disengage the pin rod 8 from the mounting post 9. Then, by forcefully rotating the tool body 1, the arc-shaped pin block 13 and the pin groove 14 will be separated by arc-shaped contact, thus completing the quick disassembly action. One end of the pull rod 4 and the pin rod 8 are fixedly connected. The tool head 2 is fixedly connected to the bottom end of the tool body 1.

[0021] Working principle: During use, the tool body 1 is first inserted into the mounting sleeve 3 to perform the installation operation. Initially, the external thread 11 engages with the inner wall of the bottom end of the mounting sleeve 3, completing the threaded upward movement. During this upward movement, the arc-shaped pin block 13 engages with the pin groove 14 and the bottom wall of the fixing ring 16 inside the mounting sleeve 3. At this time, the arc-shaped pin block 13 on the bottom wall of the fixing ring 16 engages with the pin groove 14, and the arc-shaped pin block 13 at the top of the tool body 1 engages with the pin groove 14 on the bottom wall of the fixing ring 16, indicating the locked position. Simultaneously, the mounting post 9 abuts against the pin rod 8 during the upward movement. Because the end of the pin rod 8 is arc-shaped, it provides a resisting and expanding effect. When the pin slot 14 and the arc-shaped pin block 13 are engaged and locked, the through hole 10 will be in the horizontal insertion position corresponding to the pin rod 8. Due to the elastic support of the support spring 7, the pin rod 8 and the through hole 10 can be inserted and locked. The flange 5 is connected to the drive device to complete the high-speed rotation of the tool body 1. The engraving and milling work is realized through the cutter head 2. Due to the locking of the pin rod 8 and the through hole 10, loosening and instability can be prevented, thereby achieving a high-precision and high-stability operating state. When disassembly is required, simply pull the pull rod 4 outward to disengage the pin rod 8 from the mounting post 9. Then, by forcefully rotating the tool body 1, the arc-shaped pin block 13 and the pin slot 14 will be separated by arc-shaped contact, thus completing the quick disassembly.
