[0066] Further, referring to FIGS. 1, 2 and 3, Figure 2 , Figures 6 to 9 As shown in FIGS. 1, 2 and 3, the inspection device 300 comprises a first rack 330 arranged on the carrying table 110, and a first driving mechanism 310 comprising a driven gear 311, a power assembly 312 and a horizontal moving assembly 313. The driven gear 311 is detachably sleeved outside the transmission nut 210. In the embodiment, the outer contour of the transmission nut 210 is a polygonal structure, and the driven gear 311 is provided with an installation hole 3111 penetrating through the driven gear 311 along the axial direction and matched with the outer contour of the transmission nut 210, so as to limit the mutual rotation of the transmission nut 210 and the driven gear 311.

[0067] The power assembly 312 comprises a first mounting bracket 3121, a driving gear 3122 rotatably connected with the first mounting bracket 3121, and a rotary driving member 3123 mounted on the first mounting bracket 3121. The driving gear 3122 is oppositely arranged with the driven gear 311, and the rotary driving member 3123 is drivingly connected with the driving gear 3122 and can drive the driving gear 3122 to rotate.

[0068] The horizontal moving assembly 313 is arranged on the first rack 330 and drivingly connected with the power assembly 312.

[0069] In the embodiment, the rotary driving member 3123 is specifically a rotary motor. A belt wheel set 3124 is connected between the rotary driving member 3123 and the driving gear 3122. The first mounting bracket 3121 has opposite first and second ends in the moving direction thereof. The first end is close to the driven gear 311, and the driving gear 3122 is arranged at the first end. The rotary driving member 3123 is arranged at the second end. The horizontal moving driving member 3132 can be a linear electric cylinder or a linear air cylinder. In the embodiment, an air cylinder is preferably adopted to simplify the structure.

[0070] Preferably, the driven gear 311 comprises a gear body 3112 adapted to engage with the driving gear 3122, and a mounting sleeve 3113 coaxially arranged with the gear body 3112. The power assembly 312 comprises radially limiting bearings 3125 rotatably arranged at the first end of the first mounting frame 3121, and adapted to abut against the mounting sleeve 3113 under the drive of the traversing assembly 313, so as to limit the radial play of the rotating shaft assembly of the fan 200, without limiting the rotation of the driven gear 311. Since the mounting sleeve 3113 and the radially limiting bearings 3125 are both circular in outer profile, in order to reliably abut against the mounting sleeve 3113, the number of the radially limiting bearings 3125 is two in the embodiment, and the two radially limiting bearings 3125 are adjacently arranged. The two radially limiting bearings 3125 cooperatively abut against the mounting sleeve 3113.

[0071] Further, the first detecting mechanism 320 comprises a detecting sensor 321 oppositely arranged above the nut end face 211, and a detecting drive 322, which is a linear electric cylinder or a pneumatic cylinder. The detecting drive 322 is in driving connection with the detecting sensor 321, and can drive the detecting sensor 321 to move at least in the vertical direction, so as to make the detecting sensor 321 close to and contact the nut end face 211, and through cooperation with the rotating nut end face 211, the run-out of the nut end face 211 can be effectively obtained.

[0072] Further, in order to stabilize the fan 200 during the detection process and improve the detection accuracy, the detection device 300 further comprises a first limiting mechanism 340 in the embodiment. The first limiting mechanism 340 comprises a first limiting frame 341 and a first limiting drive 342. The first detecting mechanism 320 is arranged on the first limiting frame 341. The first limiting frame 341 is in sliding connection with the first rack 330, and is oppositely arranged above the rotating disc device 100. The first limiting drive 342 is arranged on the first rack 330, and is a linear electric cylinder or a pneumatic cylinder. The first limiting drive 342 is in driving connection with the first limiting frame 341, and can drive the first limiting frame 341 to move in the vertical direction, so as to make the first limiting frame 341 close to the fan 200, and abut the housing 220 of the fan 200 against the positioning tool 140.

[0073] Preferably, the first limiting mechanism 340 further includes an axial limiting bearing 343 rotatably mounted on the first limiting frame 341. The axial limiting bearing 343 corresponds to the nut end face 211 and is adapted to abut against the nut end face 211 under the drive of the first limiting frame 341, thereby eliminating the axial backlash of the rotating shaft assembly, improving detection accuracy, and since the axial limiting bearing 343 is rotatably connected to the first limiting frame 341, it does not restrict the rotation of the transmission nut 210. The number of axial limiting bearings 343 is at least one; in this embodiment, two are preferred to improve the reliability of the abutment.

[0074] Furthermore, referring to Figure 10 and Figure 11 As shown, the milling device 400 includes a second frame 430 mounted on a support platform 110, and both the second drive mechanism 410 and the milling mechanism 420 are mounted on the second frame 430.

The lifting assembly 423 is connected to the milling power head 421 and can drive the milling power head 421 to move vertically, thereby driving the milling cutter 422 to approach and contact the nut end face 211. By cooperating with the rotating transmission nut 210, the nut end face 211 can be effectively milled.

[0076] The lifting assembly 423 includes a third mounting bracket 4231 mounted on the second frame 430 and a lifting drive component 4232 mounted on the third mounting bracket 4231.

[0077] Preferably, the milling mechanism 420 comprises a dustproof cylinder 440 and a dust suction pipe 450. The dustproof cylinder 440 is fixedly connected with the milling power head 421, and coaxially covers the milling cutter 422. The bottom of the dustproof cylinder 440 is of an elastic structure, for example, a corrugated pipe or made of rubber material. The bottom of the milling cutter 422 does not protrude relative to the dustproof cylinder 440. When the milling cutter 422 moves towards the fan 200, the dustproof cylinder 440 first contacts and abuts against the nut end face 211 to enclose the milling cutter 422 with the nut end face 211, so that the chips are prevented from flying out of the dustproof cylinder 440 when the milling cutter 422 mills the nut end face 211, and the cleanliness around the fan 200 is ensured. Preferably, the dustproof cylinder 440 covers at least part of the end face of the driven gear 311 in the axial projection, so that the driven gear 311 and the transmission nut 210 can be pressed at the same time, and the reliability of the driven gear 311 after installation is improved.

[0078] The dust suction pipe 450 is connected with the dustproof cylinder 440 at one end, and connected with a vacuum generator (not shown in the figure) at the other end. The vacuum generator can suck the chips in the dustproof cylinder 440 away, so as to avoid affecting the milling of the milling cutter 422 and the cleanliness of the fan 200 after milling.

[0079] In addition, in order to stabilize the fan 200 during milling and improve the milling accuracy, in the embodiment, the milling device 400 further comprises a second limiting mechanism 460. The second limiting mechanism 460 comprises a second limiting frame 461 and a second limiting driving member 462. The second limiting frame 461 is slidingly connected with the second rack 430, and oppositely arranged above the turntable device 100. The second limiting frame 461 is provided with an avoiding hole 4611 penetrating in the vertical direction at the position corresponding to the milling cutter 422. The inner diameter of the avoiding hole 4611 is not less than the outer diameter of the dustproof cylinder 440. The second limiting driving member 462 is drivingly connected with the second limiting frame 461. The second limiting driving member 462 is arranged on the second rack 430. The second limiting driving member 462 can be a linear electric cylinder or a pneumatic cylinder. The second limiting driving member 462 can drive the second limiting frame 461 to move in the vertical direction, so that the second limiting frame 461 approaches the fan 200, and the housing 220 of the fan 200 is abutted against the positioning tool 140.

[0080] Preferably, in order to avoid the mutual limiting of the second limiting driving member 462 and the milling power head 421, the second limiting driving member 462 is located at the bottom of the second rack 430, and the milling power head 421 is located at the top of the second rack 430.
