[0032] Furthermore, since the grinding sleeve 4 can move up and down on the outside of the vertical rod 13, and the pin 8 can engage with the insert 9, while the inner side of the arc frame 10 at the bottom of the insert 9 can provide a moving track for the upper part of the protective sleeve 11, the protective sleeve 11 will protect the grinding head 12. The user can add a rotating structure to the inside of the pin 8. This rotating structure can include a horizontal cylinder and a round hole at the upper end of the insert 9. At this time, the insert 9 and the pin 8 can drive the arc frame 10 to rotate. The user can also add lubricating oil inside the protective sleeve 11 so that when the protective sleeve 11 is placed on the outside of the grinding head 12, the lubricating oil inside the protective sleeve 11 can maintain the outside of the grinding head 12.

[0033] The following effects and novel technologies are brought about:

[0034] In terms of effects, first, the grinding head 12 is protected. The structural design of the device sets the protective sleeve 11 outside the grinding head 12 by means of the cooperation of the pin 8, the tab 9, and the arc frame 10. When the device is not working, transporting, or storing, the protective sleeve 11 can prevent the grinding head 12 from being damaged by external collisions, scratches, and the like, thereby prolonging the service life of the grinding head 12 and reducing maintenance and replacement costs due to damage to the grinding head 12. Second, the grinding head 12 is maintained. The design of adding lubricating oil liquid inside the protective sleeve 11 has good maintenance effect. When the protective sleeve 11 is set outside the grinding head 12, the lubricating oil can maintain the outside of the grinding head 12, reduce surface wear, and maintain accuracy, which helps to improve the grinding quality, make the numerical control machine tool main shaft taper hole grinding more accurate, and thus improve the machining precision of the numerical control machine tool. Third, the structure is flexible. The grinding sleeve 4 can move up and down outside the vertical rod 13. The pin 8 and the tab 9 can be connected by clamping. The tab 9 and the pin 8 can drive the arc frame 10 to flip and move after being combined. This structural combination makes the cooperation between components more diverse, and the user can adjust as needed. For example, it is more convenient to operate the components when checking or replacing the protective sleeve 11, and the operability of the device is improved. In terms of novel technology, first, the unique protective sleeve 11 installation and movement structure is a novel design that installs the protective sleeve 11 and provides a movement track through the pin 8, the tab 9, and the arc frame 10. Compared with traditional protective structures, it can not only firmly fix the protective sleeve 11 but also provide movement space to effectively protect the grinding head 12 in different working states and facilitate the installation and removal of the protective sleeve 11. Second, the multifunctional structural design adds a rotating structure such as a horizontal cylinder inside the pin 8 and a circular hole at the upper end of the tab 9, so that the tab 9 and the pin 8 can drive the arc frame 10 to flip and move after being combined. This design integrates the functions of multiple components. Based on the protection and maintenance of the grinding head 12 by the protective sleeve 11, it increases the flexibility and multifunctionality of the structure, making the device operation and use more convenient.

[0037] Among them brings the following effects and new technology:

[0038] In terms of effects, one is to reduce friction, the ball 74 is installed between the card block 73 and the side wall 5, effectively reducing the degree of friction between the card block 73 and the side wall 5, when the auxiliary structure 7 along the live rail slot 6 activity, low friction can make the card block 73 move more smoothly, thereby improving the smoothness of the entire auxiliary structure 7 operation, reducing the wear and tear of parts and prolonging the service life of the device; the second is to improve the installation strength, the user can add the number of cross 71 to improve the overall installation strength of the grinding frame 1, this feature makes the device can be adjusted according to the actual demand, in different working environment or processing requirements to enhance the stability of the grinding frame 1, because the numerical control machine tool spindle taper hole grinding precision requirements, stable grinding frame 1 helps to improve the accuracy and reliability of grinding, in the novel technology, the unique card block 73 structure and connection method is a highlight, the design of the card block 73 upper end area is less than the lower end area is very unique, in the cooperation of the card block 73 and the live rail slot 6 may have a special role, such as card into the live rail slot 6 is more convenient positioning or when bearing different direction force is more stable, and the card block 73 and the side of the cross 71 welding, and then with the installation screw assembly 72 connection and card into the side wall 5 connection method is a novel structure combination, both ensure the auxiliary structure 7 and the grinding frame 1 stable connection, also for the auxiliary structure 7 in the side wall 5 activity provides the possibility.

[0039] Working principle: when using the numerical control machine tool spindle taper hole grinding device, first, the clamp block 73 is welded with the cross 71, the cross 71 and the clamp block 73 combination part is clamped into the side wall 5 on both sides of the grinding frame 1, at this time, the vertical part in the middle of the side wall 5 is clamped into the vertical groove in the inner side of the clamp block 73, when the user moves the cross 71 up and down, the ball 74 reduces the friction degree between the cross 71, the clamp block 73 and the side wall 5, the cross 71 and the setting screw assembly 72 can help the grinding frame 1 to be fixed in the appropriate position, then the transmission box 2 drives the supporting shaft 3 and the vertical rod 13 to rotate at high speed, at this time, the grinding head 12 at the bottom end of the vertical rod 13 starts to grind the numerical control spindle, when the grinding head 12 is not used, move the grinding sleeve 4 outside the vertical rod 13, the pin 8 at the bottom end of the grinding sleeve 4 is clamped with the insert 9, at this time, the protective sleeve 11 and the arc frame 10 are located outside the grinding head 12, move the grinding sleeve 4 again, the grinding sleeve 4 drives the pin 8, the insert 9 and the arc frame 10 to move upwards, push the protective sleeve 11 inside the arc frame 10, the protective sleeve 11 is sleeved outside the grinding head 12, at this time, the outer surface of the grinding head 12 will be protected, which is the working principle of the numerical control machine tool spindle taper hole grinding device.
