[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a motor direct-drive spindle with a structure that is easy to replace, comprising: a fixing mechanism 1, the fixing mechanism 1 comprises a fixing shell 11, a motor body 12 is arranged inside the fixing shell 11, the motor body 12 is fixedly connected inside the fixing shell 11, a connecting ring 14 is arranged at one end of the motor body 12 away from the fixing shell 11, a connecting ring 2 16 is arranged at a side of the connecting ring 14 away from the motor body 12, a side of the connecting ring 14 away from the connecting ring 2 16 is fixedly connected to an end of the motor body 12 away from the fixing shell 11, fixing blocks 15 are arranged on the outer surfaces of the connecting ring 14 and the connecting ring 2 16, two fixing blocks 15 are respectively fixedly connected to the outer surfaces of the connecting ring 14 and the connecting ring 2 16, arc blocks 17 are arranged on the outer surfaces of the connecting ring 14 and the connecting ring 2 16, and the connecting ring 14 and the connecting ring 2 16 are respectively fixedly connected to the outer surfaces of the connecting ring 14 and the connecting ring 16. The outer surface of the connecting ring 2 16 is fixedly connected with an arc block 17, and one end of the arc block 17 passes through the groove opened by the fixed block 15 for limiting and fixing. A main shaft body 18 is provided on the side of the connecting ring 2 16 away from the connecting ring 1 14, and one end of the main shaft body 18 close to the connecting ring 2 16 is fixedly connected to the side of the connecting ring 2 16 away from the connecting ring 1 14. Limiting columns 19 are provided on the opposite sides of the two arc blocks 17, and the opposite sides of the two arc blocks 17 are fixedly connected to the limiting columns 19. A plurality of thread grooves 110 are opened on one side of the connecting ring 14 and the connecting ring 2 16, and a fixing piece 111 is threadedly connected inside the plurality of thread grooves 110. The outer surfaces of the fixing piece 111 are threadedly connected to the thread grooves 110 opened in the connecting ring 14 and the connecting ring 2 16, respectively. A protective mechanism 2 is provided on the side of the fixing shell 11 close to the main shaft body 18.

[0026] In this embodiment, when the staff replaces the motor direct-drive spindle, the traditional installation method requires the connection parts between the motor and the spindle to be aligned, and then the bolts are inserted into the aligned threaded holes for threaded fixation. This not only requires the staff to spend a lot of time and energy on proofreading, but also may cause safety hazards during operation. Therefore, in this device, the staff only needs to fit the connecting ring 14 and the connecting ring 2 16 together, and rotate the connecting ring 2 16 counterclockwise. During the rotation, the arc block 17 will pass through the slot opened by the fixed block 15. When rotated to a certain angle, the fixed block 15 touches the limiting column 19, thereby limiting the fixed block 15. At the same time, a certain fixed limiting effect will be obtained between the connecting ring 14 and the connecting ring 2 16, and the threaded grooves 110 respectively opened on one side of the connecting ring 14 and the connecting ring 2 16 will be aligned. The staff can insert the fixing part 111 into the threaded grooves 110 opened on the connecting ring 14 and the connecting ring 2 16 and fix them with threads. Then, the connecting part between the motor and the main shaft will be fixed, which saves the staff a lot of time and energy for proofreading and improves work efficiency.

[0030] Working principle:

[0031] like Figure 1 - Figure 4As shown, when the staff replaces the motor direct-drive spindle, they first bring the connecting ring 14 and the connecting ring 2 16 close to each other and fit them together. Next, the staff will rotate the connecting ring 2 16 counterclockwise. During this process, the arc block 17 will pass through the slot opened by the fixed block 15. When the connecting ring 2 16 rotates to a certain angle, the fixed block 15 will touch the limiting column 19, thereby limiting the fixed block 15. At the same time, a certain fixed limiting effect will be obtained between the connecting ring 14 and the connecting ring 2 16, and The threaded grooves 110 respectively opened on one side of the connecting ring 14 and the connecting ring 2 16 will be aligned, and the staff can insert the fixing part 111 into the threaded grooves 110 opened on the connecting ring 14 and the connecting ring 2 16 and fix them with threads, so that the connection part between the motor and the main shaft will be fixed. In order to protect the motor body 12 and the main shaft body 18 from damage by external factors, the equipment is also equipped with a protective cover 21. When the equipment is idle, the protective cover 21 can effectively cover the motor body 12 and the main shaft body 18 to play a protective role.
