It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0019] See also Figure 1 and Figure 2 The embodiment of the utility model discloses a cutting device with high coaxiality, comprising a lifting mechanism 1, a slide 2 connected to the lifting mechanism 1, a rotating mechanism 3 arranged on the slide 2, and a cutting mechanism 4 connected to the rotating mechanism 3. The lifting mechanism 1 can drive the slide 2 to move up and down, and the rotating mechanism 3 includes a rotating driving member 31, which is arranged on the slide 2. The lifting mechanism 1 can drive the slide 2 to move up and down, and the slide 2 can drive the rotating mechanism 3 and the cutting mechanism 4 to move up and down.

[0020] In order to enable the cutting mechanism 4 to rotate a certain angle, a rotating hole 21 is provided in the slide 2. The rotating hole 21 is a straight hole and passes through the upper surface and the lower surface of the slide 2. Compared with the traditional stepped hole, the diameter of the rotating hole 21 remains unchanged, so it is easy to process. The cutting mechanism 4 includes a tool sleeve assembly 41 and a bearing assembly 42. The bearing assembly 42 is sleeved on the outside of the tool sleeve assembly 41, and the bearing assembly 42 is arranged in the rotating hole 21. The bearing assembly 42 can enable the tool sleeve assembly 41 to rotate relative to the slide 2.

[0021] The beneficial effects of the embodiments of the utility model are as follows:

[0022] The cutting device with high coaxiality in the embodiment of the utility model is provided with a lifting mechanism 1, a slide 2, a rotating mechanism 3 and a cutting mechanism 4, wherein the lifting mechanism 1 can drive the slide 2 to lift and lower, a rotating hole 21 is provided in the slide 2, the rotating hole 21 is a straight hole and passes through the upper surface and the lower surface of the slide 2, the cutting mechanism 4 includes a tool sleeve assembly 41 and a bearing assembly 42, the bearing assembly 42 is sleeved on the outside of the tool sleeve assembly 41, and the bearing assembly 42 is arranged in the rotating hole 21. Since the rotating hole 21 is a straight hole, compared with the traditional stepped hole, the straight hole is easier to process, and it is easier to control the coaxiality within the required range, so that the bearing assembly 42 and the tool sleeve assembly 41 are not prone to problems during installation and use.

[0023] Specifically, in order to fix the bearing assembly 42 and improve the installation method of the bearing assembly 42, the knife sleeve assembly 41 includes a rotating sleeve 411, and a support platform 412 is provided on the outer wall of the rotating sleeve 411. The support platform 412 protrudes from the surface of the rotating sleeve 411, and the lower part of the bearing assembly 42 abuts on the support platform 412, and the support platform 412 is used to fix the lower part of the bearing assembly 42. In order to fix the upper part of the bearing assembly 42, the cutting mechanism 4 also includes a limiting nut 43, which is screwed to the outer wall of the rotating sleeve 411 and is located above the bearing assembly 42, and the lower part of the limiting nut 43 abuts against the upper part of the bearing assembly 42. During installation, the bearing assembly 42 is first sleeved outside the rotating sleeve 411, and the bearing assembly 42 is supported by the support platform 412 to form a limit, and then the upper part of the bearing assembly 42 is locked by the limit nut 43, so that the bearing assembly 42 and the rotating sleeve 411 form a whole, and finally the rotating sleeve 411 and the bearing assembly 42 are inserted into the rotating hole 21 to complete the installation. In the case where the rotating hole 21 is a straight hole structure, the bearing assembly 42 and the rotating sleeve 411 can form a whole and then be installed in the rotating hole 21 with a higher coaxiality, which greatly facilitates the installation operation.

[0024] Furthermore, the bearing assembly 42 includes a first bearing 421 and a second bearing 422, the first bearing 421 is located above the second bearing 422, the first bearing 421 abuts against the limit nut 43, and the second bearing 422 abuts against the support platform 412. After the first bearing 421 and the second bearing 422 are installed in the rotating hole 21, the two bearings support the rotating sleeve 411, so that the rotating sleeve 411 can rotate smoothly. Thanks to the higher coaxiality of the rotating hole 21, the first bearing 421 and the second bearing 422 can be smoothly installed in the rotating hole 21.

[0025] In addition, the bearing assembly 42 also includes a spacer ring 423, which is arranged between the first bearing 421 and the second bearing 422.
