[0021] 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.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figures 1 to 8 As shown, this utility model discloses a spindle chuck nut disassembly tool, comprising a spindle body 1, a lower support 2, and an upper support 3. A cutter 11 is mounted on the bottom end of the spindle body 1, and a wrench body 5 is externally connected to the cutter 11. The lower support 2 is located at the bottom of the spindle body 1, and the upper support 3 is fixed to the top of the lower support 2. An output shaft 22 is rotatably mounted inside the lower support 2 and the upper support 3. A connecting plate 31 is mounted on the top of the output shaft 22, a nut sleeve body 32 is mounted on the top of the connecting plate 31, and a conversion sleeve body 33 is mounted on the top of the nut sleeve body 32. A drive assembly is located inside the lower support 2, a stop block 4 is mounted on the front end of the top of the upper support 3, and a power assembly 7 is located at the front end of the lower support 2 and the upper support 3. A handle 6 is fixed to the left side of the lower support 2 and the upper support 3.

[0024] The output shaft 22 is hollow, allowing the tool 11 to pass through its interior.

[0025] The drive assembly includes a bevel gear 24 disposed inside the lower support 2. The bevel gear 24 is fixed to the outside of the output shaft 22. The front end of the top of the bevel gear 24 is meshed with a drive gear 23. The drive gear 23 is rotatably disposed inside the lower support 2. The front end of the drive gear 23 is fixed with a docking shaft 21. The docking shaft 21 protrudes from the front end of the lower support 2 and is used to connect with the power assembly 7.

[0026] Specifically, a power assembly 7 is externally connected to the docking shaft 21, and the power assembly 7 is used to provide power to the disassembly tool;

[0027] Hold the handle 6 so that the output shaft 22 is fitted onto the outside of the tool 11. Then, lock the wrench body 5 onto the outside of the tool 11. When the handle of the wrench body 5 is locked onto the left side of the stop block 4, the tool 11 is tightened. When the handle of the wrench body 5 is locked onto the right side of the stop block 4, the tool 11 is disassembled.

[0028] The output shaft 22 is fitted onto the bottom of the cutter 11. Depending on the disassembly or installation requirements, the wrench body 5 is secured to the outside of the cutter 11, with its handle positioned to the left or right of the stop block 4. Then, the power assembly 7 is activated to drive the docking shaft 21 and the drive gear 23 to rotate. The drive gear 23 drives the bevel gear 24 to rotate, thereby causing the output shaft 22 to rotate within the lower support seat 2 and the upper support seat 3. The output shaft 22 drives the connecting disc 31 and the nut sleeve body 32 to rotate. In conjunction with the action of the wrench body 5, the cutter 11 at the bottom of the spindle body 1 is turned, thus allowing the cutter 11 to be tightened or disassembled.

[0029] The drive gear 23 and the bevel gear 24 work together to increase the speed ratio and amplify the torque.

[0030] The nut sleeve body 32 is an ER32 nut sleeve, and the conversion sleeve body 33 is an ER32 to ER25 conversion sleeve. By default, the nut sleeve body 32 is installed on the top of the connecting plate 31, which can be used to disassemble or tighten the ER32 tool 11. When it is necessary to disassemble or tighten the ER25 tool 11, the conversion sleeve body 33 is installed on the top of the nut sleeve body 32.

[0031] Different types of power units 7 can be installed at the docking shaft 21, such as Figure 7 and Figure 8 As shown, a regular electric wrench is connected to the power unit 7.
