[0043] Preferably, the side wall of the small diameter portion 512 opposite to the cylinder 3 is provided with a support hole that is slidingly fitted with the telescopic rod 31; the telescopic rod 31 passes through the support hole and is fixedly connected to the positioning cylinder 513; , The positioning cylinder 513 can move axially in the positioning sleeve 51 under the action of the telescopic rod 31; in addition, the inner diameter of the small diameter portion 512 is adapted to the outer diameter of the positioning cylinder 513; the axial length of the positioning cylinder 513 is the same as the small diameter The axial lengths of the portions 512 are equal so that the small-diameter portion 512 can exactly accommodate the positioning cylinder 513.
[0044] The sleeve pushing structure 6 includes a cylindrical sleeve fixing portion 61 that pushes the sleeve 11 to the large diameter portion 511; the sleeve fixing portion 61 is fixed on the support 2 by a fixing table 62; the sleeve A fixing hole 611 adapted to the outer shape of the sleeve is provided at the axis of the fixing portion 61; a pushing block 63 that can move axially along the fixing hole 611 is arranged on the outer side of the sleeve fixing portion 61; the pushing block 63 and The second telescopic rod 41 on the second oil cylinder 4 is fixedly connected; the push block 63 is a cylindrical body, and the diameter of the push block 63 is between the diameter of the central hole in the sleeve 11 and the diameter of the fixed hole 611, so that the telescopic rod 31 drives the positioning cylinder When 513 retracts to the small diameter part 512, the second telescopic rod 41 can push the sleeve 11 in the fixing hole 611 to the axis of the large diameter part 511 through the push block 63, thereby realizing the installation of the rotor 1; in addition, the positioning cylinder 513 In the process of moving in the axial direction, the burr and other processing defects on the inner circle of the annular magnetic conductive sheet 12 can be smoothed to a certain extent, so as to avoid jamming when the sleeve 11 enters. In the present invention, the large-diameter portion 511, the small-diameter portion 512, and the sleeve fixing portion 61 are all coaxially arranged to ensure that the sleeve 11 is accurately pushed to the axis of the large-diameter portion 511.
[0045] Preferably, in order to ensure that the first annular baffle 13, the annular magnetic sheet 12 and the second annular baffle 14 are flush with the sleeve in the vertical direction, the outer diameter of the sleeve fixing portion 61 is slightly smaller than or equal to The inner diameter of the large diameter portion 511; so that when the first annular baffle 13, the annular magnetic sheet 12 and the second annular baffle 14 are sleeved on the positioning cylinder 513, the sliding table 52 drives the rotor assembly structure 5 to move to the sleeve At the pipe pushing structure 6, the opposite sides of the sleeve fixing portion 61 and the large diameter portion 511 are closely attached to ensure that the first annular baffle 13, the annular magnetic sheet 12, and the second annular shape are vertical in the large diameter portion 511. Straightness and axial installation are in place.
[0046] In general, the removal of the rotor 1 after the installation is complete is to pass some top pieces through the side wall of the installation tool, thereby topping the rotor 1; however, because the rotor 1 is tightly integrated with the inner wall of the installation tool, this method is not easy to ensure the cover The tube 11 and the annular magnetic sheet 12 are removed at the same time; therefore, the bottom of the large-diameter portion 511 is detachably connected to the side wall in the present invention; specifically, the distance between the bottom of the large-diameter portion 511 and the side wall is axially A number of connecting bolts 53 are evenly distributed in the circumferential direction to facilitate the removal of parts.
[0047] In order to make the removal more convenient, the side wall of the large-diameter part 511 is formed by buckling two semi-circular shells 514 with the same shape, so that it can be easily realized by removing the two semi-circular shells 514 in different directions. All parts of the rotor 1 are unloaded simultaneously.
[0048] In the present invention, since the annular magnetic conductive sheet 12, the first annular baffle 13 and the second annular baffle 14 are closely integrated with the positioning cylinder 513, in order to smoothly retract the positioning cylinder 513 to the small diameter portion 512 and ensure that the sleeve 11 is pushed into the large diameter In the part 511, lubrication measures need to be taken in the central holes of the annular magnetic conductive sheet 12, the first annular baffle 13 and the second annular baffle 14.

[0051] S2. The operator sequentially sets the first annular baffle 13, the annular magnetic conductive sheet 12 and the second annular baffle 14 on the positioning cylinder 513;
[0052] S3. The operator inserts the sleeve 11 into the fixing hole 611 of the sleeve fixing portion 61;
[0053] S4, such as image 3 As shown, the sliding table 52 is adjusted to move the rotor assembly structure 5 until it fits with the sleeve pushing structure 6, so as to ensure the verticality of the connected components;
[0054] S5. Open the cylinder one 3, slowly drive the positioning cylinder 513 to move to the side of the small diameter part 512 through the telescopic rod one 31, and open the cylinder one 3 at the same time, and the push block 63 will move the sleeve 11 at the same speed under the action of the telescopic rod two 41 Squeeze into the large diameter part 511;
[0055] S6, such as Figure 4 As shown, when the positioning cylinder 513 is completely located in the small diameter portion 512, the telescopic rod 31 stops moving; at this time, the sleeve 11 is also completely located in the large diameter portion 511, and the rotor 1 is assembled;
