[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-6 As shown, this utility model provides a disassembly and assembly structure for a metal cutting tool, including a mounting base 1 connected to a mechanical device and a tool body. The tool body includes a tool holder 2 and a tool head 3. One end of the mounting base 1 is provided with a insertion groove 4 that is adapted to the tool holder 2. A connector 5 is provided in the center of the inner side of the insertion groove 4. One end of the tool holder 2 is provided with a mating groove 6 that is adapted to the connector 5. A snap-fit ​​mechanism is provided inside the insertion groove 4 to facilitate the disassembly and assembly of the tool body.

[0023] Specifically, the design of the insertion slot 4 and the snap-fit ​​mechanism enables the quick installation and disassembly of the tool body. The cooperation of the connector 5 and the mating slot 6 ensures the accurate positioning of the tool body during installation. Thus, the above structure enables the quick disassembly and assembly and stable connection of metal cutting tools. Its design is reasonable and easy to operate, making it suitable for machining scenarios that require frequent tool changes.

[0024] The locking mechanism includes a locking ball 10. The outer ring of the mounting base 1 has multiple sets of storage slots 9, each holding a locking ball 10. A fixing ring 11 is sleeved on the side of the outer ring of the mounting base 1 away from the storage slots 9. A sliding sleeve 12 is slidably connected to the outer ring of the fixing ring 11. An annular contact plate 13, which abuts against the multiple sets of locking balls 10, is provided on the inner side of the sliding sleeve 12 away from the fixing ring 11. The contact plate 13 is connected to the fixing ring 11 via a spring 14 sleeved on the outer ring of the mounting base 1. The outer ring of the tool holder 2 has an annular locking groove 15 adapted to the multiple sets of locking balls 10. By sliding the sliding sleeve 12 towards one end of the mounting base 1, the sliding sleeve 12 can move the contact plate 13 to one side and compress the spring 14. Then, the tool holder 2 of the tool body is aligned with the insertion slot 4 of the mounting base 1 and inserted. The end of the tool holder 2 gradually approaches the locking ball 10. As the tool holder 2 continues to penetrate deeper, the outer ring of the annular groove 15 will squeeze the retaining ball 10 and cause it to retract completely into the storage groove 9. When the tool holder 2 is fully inserted, and the annular groove 15 on the tool holder 2 moves to the position corresponding to the retaining ball 10, the sliding sleeve 12 is released. Under the action of the reaction force of the spring 14, the sliding sleeve 12 can drive the abutment plate 13 to move in the opposite direction. While the abutment plate 13 moves in the opposite direction, it can squeeze multiple sets of retaining balls 10 towards the inside of the storage groove 9 and squeeze part of the balls of multiple sets of retaining balls 10 through the inside of the annular groove 15. Through the tight cooperation between the retaining ball 10 and the annular groove 15, a quick connection between the tool body and the mounting base 1 can be achieved. Through the reverse operation, the quick disassembly and assembly of the tool body and the mounting base 1 can be facilitated. Thus, through the setting, the quick disassembly and assembly and stable connection of the tool body are achieved.

[0025] The inner side of the sliding sleeve 12 near one end forms a movable cavity 16 with the contact plate 13 to facilitate the movement of the ball 10. The movable cavity 16 provides sufficient space for the ball 10 to move, ensuring that the ball 10 can extend and retract flexibly during installation and disassembly. The design of the movable cavity 16 makes the movement of the ball 10 more stable, avoiding jamming or obstruction of the ball 10. With the cooperation of the movable cavity 16, the operation of the locking mechanism is made easier, and the efficiency of disassembly and assembly is improved.

[0026] The mounting base 1 is threaded with a locking screw 17 near one end. One end of the locking screw 17 extends into the inner side of the insertion groove 4 and abuts against the tool holder 2. After the tool holder 2 of the tool body is inserted into the insertion groove 4 of the mounting base 1 and fixed by the snap-fit ​​mechanism, the locking screw 17 is rotated to push it into the inner side of the insertion groove 4. One end of the locking screw 17 can abut against the tool holder 2 to apply pressure and further fix the tool body, ensuring that the tool body will not loosen during operation. Thus, the installation stability of the tool is further improved by this design.

[0027] The inner wall of the insertion slot 4 is provided with four sets of limiting slots 7, and the outer ring of the tool holder 2 is provided with four sets of matching limiting strips 8. Through the cooperation of the limiting strips 8 and the limiting slots 7, the tool body can be accurately positioned during installation to prevent rotation. At the same time, it can prevent the tool body from shifting during operation.

[0028] Working principle: First, by sliding the sliding sleeve 12 to one end of the mounting base 1, the sliding sleeve 12 can drive the abutment plate 13 to move to one side and compress the spring 14. Then, the tool holder 2 of the tool body is aligned with the insertion slot 4 of the mounting base 1 and inserted. The end of the tool holder 2 gradually approaches the retaining ball 10. As the tool holder 2 continues to go deeper, the outer ring of the annular retaining groove 15 will squeeze the retaining ball 10 and make it completely retract into the storage groove 9. When the tool holder 2 is fully inserted and the annular retaining groove 15 on the tool holder 2 moves to the position corresponding to the retaining ball 10, the sliding sleeve 12 is released. Under the action of the reaction force of the spring 14, the sliding sleeve 12 can drive the tool holder 13 to move to the side. The contact plate 13 moves in the opposite direction. While the contact plate 13 moves in the opposite direction, it can squeeze multiple sets of retaining balls 10 into the inside of the receiving groove 9 and squeeze part of the balls of multiple sets of retaining balls 10 through the inside of the annular retaining groove 15. Through the tight cooperation between the retaining balls 10 and the annular retaining groove 15, the tool body and the mounting base 1 can be quickly connected. Then, by rotating the locking screw 17, it is pushed into the inside of the insertion groove 4. One end of the locking screw 17 can abut against the tool holder 2 and apply pressure to further fix the tool body and ensure that the tool body will not loosen during operation, thus completing the entire operation process.

[0029] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
