The following is a detailed explanation.

[0042] See also Figure 1In one embodiment, the positioning mechanism is used to position the bearing cover plate 10, and the positioning mechanism includes two groups of positioning components 20, and the two groups of positioning components 20 are spaced apart along a circumferential direction. In this embodiment, the two groups of positioning components 20 are symmetrically arranged on both sides of a circumferential radial direction, that is, symmetrically arranged on both sides of the bearing cover plate 10 with positioning, and a positioning space 70 is enclosed between the two groups of positioning components 20; the positioning component 20 includes a mounting plate 21, a bearing plate 22, a positioning plate 23, a first driving structure 24 and a second driving structure 25, the first driving structure 24 and the second driving structure 25 are respectively arranged on the mounting plate 21, the first driving structure 24 is used to drive the bearing plate 22 to move toward the center of the positioning space 70, the bearing plate 22 is used to lift the bearing cover plate 10, that is, the two bearing plates 22 can be arranged close to or away from each other, and the two The bearing plates 22 are driven by the first driving structure 24 to adjust the distance between the two bearing plates 22 so as to be suitable for lifting bearing cover plates 10 of different sizes, and the applicability is strong; the second driving structure 25 is used to drive the positioning plate 23 to move toward the center of the positioning space 70, and the second driving structure 25 applies a force to the bearing cover plate 10 through the positioning plate 23, and the force points to the center of the positioning space 70. Under the drive of the second driving structure 25, the two positioning plates 23 move toward each other to clamp the bearing cover plate 10 between the two positioning plates 23, and the clamping force of the positioning plate 23 on the bearing cover plate 10 (that is, the above-mentioned force) is directed toward the center of the positioning space 70, so that the bearing cover plate 10 is positioned at the center of the positioning space 70, that is, the bearing cover plate 10 is centered (the center position of the bearing cover plate 10 is determined).

[0043] In actual operation, the above-mentioned supporting plate 22 is first driven by the above-mentioned first driving structure 24, and the two supporting plates 22 are driven to the bottom of the positioning bearing cover plate 10 to lift the bearing cover plate 10. Then, the above-mentioned positioning block is driven by the above-mentioned second driving structure 25 to move toward the above-mentioned bearing cover plate 10 until the above-mentioned two positioning blocks clamp the above-mentioned bearing cover plate 10, and the positioning operation of the bearing cover plate 10 is completed at the same time, and the bearing cover plate 10 is positioned at the center of the above-mentioned positioning space 70.

[0044] It should be noted that the number of the above-mentioned positioning components 20 includes at least two groups. In some embodiments, it can be three groups or four groups, etc., but it is not limited to this. In some embodiments, the above-mentioned multiple positioning components 20 can be evenly spaced when distributed in a circumferential direction. Such an arrangement makes the circumferential side of the bearing cover plate 10 evenly stressed, which is more conducive to the positioning operation of the bearing cover plate 10. It will not be repeated here.

The above-mentioned supporting plate 22 is slidably connected to the above-mentioned mounting plate 21. The above-mentioned sliding connection setting is conducive to the stable movement of the above-mentioned supporting plate 22, thereby ensuring the stability of the supporting plate 22 in lifting the bearing cover plate 10 to be positioned, and effectively improving the accuracy of positioning the bearing cover plate 10. At the same time, through the setting of the above-mentioned main body 221 and the above-mentioned two limiting parts 222, the above-mentioned supporting plate 22 is sleeved on the above-mentioned mounting plate 21, with a compact structure, which is conducive to reducing space occupancy; in addition, the above-mentioned first driving structure 24 and the above-mentioned second driving structure 25 are both arranged on the above-mentioned mounting part 211, that is, arranged on the other side of the above-mentioned mounting plate 21, with a compact structure, which is conducive to the layout of components, and will not be repeated here.

[0046] It should be noted that the above-mentioned supporting plate 22 and the above-mentioned mounting plate 21 can also be connected in other forms. For example, in some embodiments, a slide rail structure can be set between the above-mentioned supporting plate 22 and the above-mentioned mounting plate 21 to improve the stability of the movement of the supporting plate 22. This is not limited to this and will not be repeated here.

[0047] Please continue reading Figure 2 and Figure 3 In one embodiment, the positioning assembly 20 has a first direction (eg Figure 2-4 as well as Figure 7 The first direction is perpendicular to the mounting plate 21; the positioning assembly 20 further comprises a first stopper 26, which is disposed on a side of the stopper 222 away from the main body 221. In the first direction, the first stopper 26 is at least partially opposite to the sliding portion 212 (as shown in FIG. Figure 7 As shown), that is, in the first direction, the first limit block 26 is arranged opposite to the main body 221, and the first limit block 26, the main body 221 and the limit portion 222 are collectively enclosed into a sliding space, and the sliding portion 212 is slidably connected in the sliding space, which is beneficial to improving the stability of the movement of the supporting plate 22, thereby ensuring the stability of the supporting plate 22 in supporting the bearing cover plate 10 to be positioned, effectively improving the accuracy of the positioning of the bearing cover plate 10, and the structure is compact.

[0048] Furthermore, in the first direction, the size of the sliding portion 212 is larger than the size of the mounting portion 211, and the mounting portion 211 is flush with the side of the sliding portion 212 away from the main body 221, that is, the surface of the sliding portion 212 relative to the main body 221 is higher than the surface of the mounting portion 211 relative to the main body 221, and the mounting plate 21 is stepped, and the first drive structure 24 and the second drive structure 25 are arranged on the lower mounting portion 211, which is beneficial to reducing the overall size in the first direction and is beneficial to the overall layout of the device; at the same time, the mounting plate 21 is flush with the side away from the main body 221, which is convenient for the installation and leveling of the mounting plate 21. Of course, in some embodiments, it can be arranged in other forms, which will not be repeated here.

[0049] See also Figure 3 , Figure 5 and Figure 6 In one embodiment, the first driving structure 24 includes a power element 241, a driving shaft 242, and a connecting structure 243 arranged between the driving shaft 242 and the main body 221. The driving shaft 242 can reciprocate along its axial direction under the action of the power element 241, and then drive the main body 221 (carrying plate 22) to reciprocate through the connecting structure 243. The connecting structure 243 includes a connecting block 2431 connected to the driving shaft 242 and a connecting groove 2432 arranged on the side of the main body 221 facing the driving shaft 242. The connecting block 2431 is embedded in the connecting groove 2432. By embedding the connecting block 2431 in the connecting groove 2432, the connection and installation of the connecting block 2431 and the connecting groove 2432 can be facilitated.

[0050] It should be noted that the power element 241 may be a pneumatic cylinder, an electric cylinder or a hydraulic cylinder, which is determined according to actual use requirements and is not specifically limited here; the connection block 2431 and the drive shaft 242 may be threadedly connected or pin-connected, which is not specifically limited here, and it is sufficient to ensure that the connection block 2431 can move with the drive shaft 242.

[0051] Furthermore, in the axial direction of the driving shaft 242, the connecting block 2431 has a first connecting portion 24311 and a second connecting portion 24312, the second connecting portion 24312 is farther away from the driving shaft 242 than the first connecting portion 24311, and the cross-sectional area of ​​the first connecting portion 24311 is smaller than the cross-sectional area of ​​the second connecting portion 24312 (i.e. Figure 5 and Figure 6The longitudinal dimension of the connecting block 2431 is larger on the side close to the main body 221, so that the connection between the first connecting portion 24311 and the second connecting portion 24312 forms a first limiting surface 24313; the connecting groove 2432 has a first groove section 24321 and a second groove section 24322, and the second groove section 24322 is farther away from the driving shaft 242 than the first groove section 24321. In the radial direction of the driving shaft 242, the size of the first groove section 24321 is smaller than the size of the second groove section 24322 (i.e. Figure 5 and Figure 6 In the perspective, the longitudinal dimension of the connecting groove 2432 is larger on the side close to the main body 221), so that the second limiting surface 24323 is formed at the connection between the first groove section 24321 and the second groove section 24322; in the axial direction of the driving shaft 242, the first limiting surface 24313 and the second limiting surface 24323 are at least partially opposite to each other, which can ensure that the connecting block 2431 is limited in the connecting groove 2432 in the axial direction of the driving shaft 242, and at the same time, in the axial direction of the driving shaft 242, the second connecting The size of portion 24312 is smaller than the size of the second groove section 24322. With such an arrangement, when the driving shaft 242 drives the connecting block 2431, the connecting block 2431 and the connecting groove 2432 are floatingly connected (that is, there can be a certain movable space between the connecting block 2431 and the connecting groove 2432 in the axial direction of the driving shaft 242), thereby avoiding the connecting block 2431 from getting stuck between the supporting plate 22 and the mounting plate 21 when driving the supporting plate 22, thereby ensuring the smooth movement of the supporting plate 22 and facilitating the automation process.

[0052] It should be noted that the cross section is obtained by cutting the connecting block 2431 through a plane perpendicular to the axial direction of the driving shaft 242; it should also be noted that in some embodiments, the second driving structure 25 is disposed above the first driving structure 24 through a suspension 252 (e.g. Figure 2 As shown), the second driving structure 25 can be a driving cylinder (not shown in the figure), which is connected to the positioning plate 23 through the mounting block 251 to realize the movement of the positioning plate 23, and a connecting block 2431 and a connecting groove 2432 are also provided between the driving cylinder and the connecting block 2431. The details are not repeated here. Through the setting of the above-mentioned suspension 252, the above-mentioned first driving structure 24 and the above-mentioned second driving structure 25 are arranged up and down, with a compact structure, reducing space occupancy, and being conducive to the layout of automated equipment. Details are not repeated here.

[0053] See also Figure 7In one embodiment, the sliding portion 212 has a limiting groove 2121 on one side relative to the main body 221, and the limiting groove 2121 extends along the axial direction of the driving shaft 242, and the connecting block 2431 is partially accommodated in the limiting groove 2121, which is beneficial to reducing the height in the first direction and reducing space occupancy; in addition, the main body 221 has an avoidance groove 2211 on one side relative to the sliding portion 212, and the avoidance groove 2211 extends along a side away from the mounting portion 211 (i.e., extends along the axial direction of the driving shaft 242). Such a configuration can reduce the contact area between the sliding portion 212 and the main body 221, reduce the friction between the two, and further ensure the smooth movement of the supporting plate 22.

[0054] It should be noted that, in some embodiments, the above-mentioned limiting groove 2121 is not a through groove, that is, when the above-mentioned connecting block 2431 moves, it will abut against the groove wall of the limiting groove 2121 relative to the connecting block 2431, thereby achieving the limitation of the connecting block 2431, limiting the moving distance, and preventing the supporting plate 22 from falling off from the sliding connection part 212.

[0055] See also Figure 4 and Figure 7 In one embodiment, the positioning assembly 20 further includes a second limit block 27, which is disposed on a side of the supporting plate 22 away from the mounting plate 21, and the second limit block 27 includes a fixing portion 271 and a positioning portion 272, wherein the fixing portion 271 is disposed on the supporting plate 22, and in the first direction, the positioning portion 272 and the supporting plate 22 are spaced apart from each other, and the positioning plate 23 is partially slidably connected between the positioning portion 272 and the supporting plate 22, and through the provision of the second limit block 27, the positioning block is confined between the positioning portion 272 and the supporting plate 22 to ensure the sliding stability of the positioning plate 23, and through the provision of the positioning portion 272, the positioning plate 23 is limited to be displaced in the first direction to ensure that the force applied by the positioning plate 23 to the bearing cover plate 10 is in the horizontal direction, thereby effectively improving the quality of positioning the bearing cover plate 10.

[0056] In addition, in one embodiment, the side of the positioning plate 23 facing the bearing cover plate 10 includes at least two wall surfaces 231. In this embodiment, three wall surfaces 231 are provided, and the wall surfaces 231 are adjacent to each other and arranged at an angle.

The specific installation steps are as follows: clamp the rotating part 31 through the clamping mechanism 50, move the rotor 30 (including the bearing 40 and the bearing cover plate 10) into the positioning space 70, at which time the rotating shaft 32 is located at the center of the positioning space 70, start the first driving structure 24 to drive the bearing plates 22 to move closer to each other until they are located below the positioned bearing cover plate 10, and move downward through the clamping mechanism 50 until the bearing cover plate 10 falls on the bearing plate 22 (as shown). Fig.10 As shown, the clamping mechanism 50 is omitted in the figure), the second driving structure 25 is started, and the positioning plate 23 is moved toward the bearing cover plate 10 until the bearing cover plate 10 is clamped, and the positioning of the bearing cover plate 10 is completed.
