[0001] The utility model relates to the technical field of motor manufacturing, in particular to a fixing structure of a motor shaft. Background Art

[0002] In order to ensure the coaxiality and installation accuracy of the overall structure of the rotor core, the shaft needs to be fixed axially during assembly without affecting its rotation. However, due to the large overall mass of the shaft and the rotor core, it is rather troublesome to fix the shaft solely by manpower, and manpower has great instability, making it difficult to ensure the stability of the motor shaft.

[0003] For example, a motor shaft fixing device with Chinese patent number CN220087129U is disclosed, in which a support wheel of the fixing device slides in a slide groove through a connecting rod to realize movement along the length direction of the mounting portion, and a plurality of spaced positioning holes are provided on the mounting portion, and the positioning holes are arranged corresponding to and connected to the slide groove, and bolts, latches and other fixing parts can be inserted into the interior of the connecting rod along the positioning holes and the slide groove for locking. The locking method is limited by the positioning holes, so that it can only be applied to the motor shaft with an inner diameter corresponding to the position of the positioning holes, so a motor shaft fixing structure is proposed to solve the above-mentioned problems. Utility Model Content

[0006] A bidirectional screw is connected inside the rotating frame, a handle is connected to one side of the bidirectional screw, a slide groove is opened inside the rotating frame, a slider is connected inside the slide groove, and a support wheel is connected to one side of the slider;

[0007] A threaded block is connected to one side of the fixing frame, and a threaded rod is connected inside the threaded block.

[0008] Furthermore, there are two rotating frames and two fixed frames, and the shapes of the rotating frames and the fixed frames are both U-shaped. The two rotating frames and the fixed frames are respectively distributed front and back.

[0009] Furthermore, the bidirectional screw is clamped and rotatably connected to the rotating frame, and the handle is L-shaped and located outside the rotating frame.

[0010] Furthermore, the slide groove is located at the front end of the rotating frame, and the sliding block is plugged into and slidably connected with the slide groove.

[0011] Furthermore, the slider is threadedly connected to the bidirectional screw, and one end of the slider close to the supporting wheel is clamped and rotatably connected to the supporting wheel, and the supporting wheel is located on the front side of the rotating frame.

[0012] Furthermore, two support wheels are arranged on the front sides of the two rotating frames, the threaded rod is located just above the middle position of the two support wheels, and the threaded rod is threadedly connected to the threaded block.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The fixing structure of the motor shaft is provided with a rotating frame, and the bidirectional screw can be linked to rotate by rotating the handle, so that the sliding block is linked to move along the bidirectional screw in the sliding groove.

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.

[0021] See also Figure 1-3 In this embodiment, a fixing structure of a motor shaft includes a base frame 1, a rotating frame 2 is connected to the top of the base frame 1, a bidirectional screw 201 is connected to the inside of the rotating frame 2, a handle 202 is connected to one side of the bidirectional screw 201, a slide groove 203 is opened inside the rotating frame 2, a slider 204 is connected to the inside of the slide groove 203, a support wheel 205 is connected to one side of the slider 204, a fixed frame 3 is connected to the top of the rotating frame 2, a threaded block 301 is connected to one side of the fixed frame 3, and a threaded rod 302 is connected to the inside of the threaded block 301.

[0022] In the case implementation, there are two rotating frames 2 and two fixed frames 3, and the shapes of the rotating frames 2 and the fixed frames 3 are both U-shaped. The two rotating frames 2 and the fixed frames 3 are respectively distributed front and back, so the motor shaft can be well supported and fixed by the two rotating frames 2 and the fixed frames 3.

By rotating the handle 202, the bidirectional screw 201 can be linked to rotate, thereby linking the slider 204 to move along the bidirectional screw 201 in the slide groove 203.

[0024] In the case implementation, one end of the slider 204 close to the support wheel 205 is clamped and rotatably connected to the support wheel 205, and the support wheel 205 can rotate relative to the slider 204. The support wheel 205 is located on the front side of the rotating frame 2. Two support wheels 205 are provided on the front sides of the two rotating frames 2. The threaded rod 302 is located directly above the middle position of the two support wheels 205.

[0026] 1) First, adjust the distance between the two support wheels 205 on the front sides of the two rotating frames 2 according to the inner diameter of the motor shaft;

[0027] 2) The handle 202 is rotated to link the bidirectional screw 201 to rotate, and the bidirectional screw 201 rotates to link the slider 204 to move along the bidirectional screw 201 in the slide groove 203;

[0028] 3) Then place the motor shaft on the two supporting wheels 205 of the two rotating frames 2;

[0029] 4) Finally, rotate the threaded rod 302 until the threaded rod 302 abuts against the motor shaft.

[0030] In summary, the fixing structure of the motor shaft can well support and fix the motor shaft through the two rotating frames 2 and the fixing frame 3.

[0031] In addition, the bidirectional screw 201 can be rotated in conjunction with the handle 202, thereby the slider 204 can be moved along the bidirectional screw 201 in the slide groove 203.
