The stator is fixed on the casing, and the rotor is inserted into the stator and connected to the end covers of the casing through a rotating shaft. In order to reduce the friction between the rotating shaft and the end covers of the casing, bearings will be installed on the rotating shaft. The installation of the bearings is generally completed by machine stamping, but workers are required to load the bearings before this stamping. Compared with the machine stamping that is completed quickly, the efficiency of the entire bearing installation work is mainly affected by the workers' loading efficiency.

[0034] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1 As shown, a rotor pressing device is used to press bearing 1 and bearing 2 onto both ends of a rotor, comprising: a processing frame 1, a rotor processing device 2 and a rotor feeding device 4, wherein the processing frame 1 serves as a working platform, the rotor processing device 2 is arranged on the processing frame 1, the rotor feeding device 4 is arranged on the rotor processing device 2, the rotor feeding device 4 feeds the bearing onto the rotor processing device 2, and the rotor processing device 2 can press the bearing onto the rotor.

[0036] Specifically, the rotor processing device 2 includes a rotor clamping mechanism 33, a fixed mold plate 21, a movable mold plate 22 and a movable mold driving mechanism 23. The movable mold driving mechanism 23 can drive the movable mold plate 22 of the rotor processing device 2 and the rotor positioning device 3 to move toward the fixed mold plate 21, and the bearing 1 and the bearing 2 are respectively loaded on the movable mold plate 22 and the fixed mold plate 21, so as to realize the pressing of the bearings on both ends of the rotor.

[0037] like Figure 2 As shown, a positioning plate 11 is provided in the middle of the processing frame 1, the movable platen 22 and the movable platen driving mechanism 23 are respectively arranged on both sides of the positioning plate 11, the rotor clamping mechanism 33 is arranged at the front end of the movable platen 22, and the fixed platen 21 is arranged at the front end of the rotor clamping mechanism 33. The rotor pressing equipment is arranged horizontally as a whole. Compared with the problem of low concentricity caused by vertical pressing of bearings, when the pressure of pressing the bearings gradually increases, the horizontal setting can ensure a higher concentricity between the bearings and the rotor. Since the rotor clamping mechanism 33 always supports the rotor horizontally, the stability of the bearings can also be ensured.

[0038] Furthermore, at least two movable mold guide rods 12 are arranged between the fixed mold plate 21 and the positioning plate 11. The movable mold plate 22 is movably arranged on the movable mold guide rod 12. Both the fixed mold plate 21 and the fixed plate are provided with a plurality of through holes for installing the movable mold guide rod 12. The vertex of the movable mold plate 22 also has a plurality of through holes. The movable mold plate 22 is movably arranged on the movable mold guide rod 12 through the through holes. Compared with adding a slide rail to guide the movable mold plate 22, the structure of the movable mold guide rod 12 is simpler and more practical.

[0039] Furthermore, corresponding fixed mold feeding mechanisms 211 and movable mold feeding mechanisms 221 are provided on the fixed mold plate 21 and the movable mold feeding mechanisms 221. Both the fixed mold feeding mechanisms 211 and the movable mold feeding mechanisms 221 can accommodate multiple bearings stacked on each other. After personnel manually place the bearings therein, the fixed mold feeding mechanisms 211 and the movable mold feeding mechanisms 221 can realize automatic loading of the bearings. Compared with personnel manually loading the bearings one by one, the fixed mold feeding mechanisms 211 and the movable mold feeding mechanisms 221 have higher loading efficiency.

[0040] like Figure 3-Figure 6 As shown, the structural settings of the fixed mold feeding mechanism 211 and the movable mold feeding mechanism 221 are generally the same, and the difference lies in the different settings and the different directions of bearing feeding. The fixed mold feeding mechanism 211 is selected for introduction here. The fixed mold plate 21 has a slot, and the fixed mold feeding device is tilted on the fixed mold plate 21 through the slot. The tilted setting method can ensure that personnel can better observe the bearing storage situation in the fixed mold feeding mechanism 211, and can make the bearing more stably placed in the fixed mold feeding mechanism 211 to ensure that it will not tip over due to equipment vibration.

[0041] Furthermore, the fixed mold feeding mechanism 211 includes: a bearing storage portion 40, a bearing positioning portion 42 and a bearing pushing unit. The bearing storage portion 40 is arranged on the fixed mold plate 21 through a bearing receiving plate 41, and has a bearing storage cavity 52; the bearing positioning portion 42 is arranged on the fixed mold plate 21, and has a bearing positioning groove 43, and is located next to the rotor clamping mechanism 33, and is also connected to the feeding channel 44 of the bearing receiving plate 41; the bearing pushing unit has a bearing pushing plate 46 that can push the bearing from the feeding channel 44 to the bearing positioning groove 43.

[0042] Specifically, the bottom surface of the bearing receiving plate 41 abuts against the slot of the mounting plate, and a plurality of support frames are arranged on the bottom surface of the bearing receiving plate 41. The support frames are also mounted on the side of the mounting plate by screws, which can ensure that the bearing receiving plate 41 is stably arranged. A bearing feeding channel 44 is also provided on the bearing receiving plate 41, and the bearing can move in the bearing feeding channel 44.

[0043] The bearing storage section 40 is vertically arranged on the bearing receiving plate 41, and has a bearing storage cavity 52 for accommodating bearings. The whole is in the shape of an elongated strip. The size of the bearing storage cavity 52 is adapted to the outer diameter of the bearing. The bearings can be stacked and placed together in the bearing storage cavity 52.

[0044] The bearing pushing unit is arranged on the side wall of the bearing receiving plate 41 , and comprises a pushing driving member 45 and a bearing pushing plate 46 movably disposed in the bearing feeding channel 44 . The bearing pushing plate 46 can push the bearing out to move it into the bearing positioning groove 43 .

[0045] like Figure 3-Figure 6 As shown, the bearing storage section 40 includes: a material channel fixed plate 50, which is arranged on the bearing receiving plate 41; and a material channel movable plate 51, which is slidably arranged on the material channel fixed plate 50; the material channel movable plate 51 can slide upward on the material channel fixed plate 50 so that its lower part is separated from the bearing receiving plate 41. At this time, the bearing can be manually placed into the bearing storage cavity 52.

[0046] Furthermore, a semicircular groove 1 is axially penetrated on the material channel fixed plate 50, and a semicircular groove 2 is axially penetrated on the material channel movable plate 51. The semicircular groove 1 and the semicircular groove 2 are interconnected and cooperate to form a bearing storage cavity 52. ​​The material channel fixed plate 50 and the material channel movable plate 51 themselves can seal and protect the bearing in the bearing storage cavity 52, and during the process of feeding the bearing, the bearing is waterproof and dust-proof, thereby increasing the service life of the bearing.

[0047] Furthermore, in order to ensure the stability of the material channel movable plate 51 when sliding, the material channel movable plate 51 is slidably set on the material channel fixed plate 50 through a clamping structure, and the clamping structure has at least: a clamping groove 53, which is formed on both sides of the material channel fixed plate 50; and a clamping portion 54, which is protrudingly formed on both sides of the material channel movable plate 51 and is movably clamped in the clamping groove 53. When the clamping portion 54 moves in the clamping groove 53, the clamping groove 53 can provide a guiding effect.

[0048] like Figure 3-Figure 6 As shown, the feeding mechanism also includes a bearing positioning portion 42 and a bearing stopper module. The bearing positioning portion 42 is arranged on the mounting plate and is located below the bearing feeding channel 44, and has a bearing positioning groove 43 for loading the bearing; the bearing stopper module is arranged on the sliding bearing feeding module and is located beside the bearing feeding channel 44, and is used to limit the bearing in the bearing positioning groove 43 to prevent it from rolling out of the bearing positioning groove 43.

[0049] Furthermore, the bearing material blocking module includes: a material blocking drive 47, which is arranged on the bearing receiving plate 41 through a material blocking base 48; and a material blocking plate, which is arranged at the output end of the material blocking drive 47 and moves at the notch of the bearing positioning groove 43. The material blocking drive 47 can drive the material blocking plate to move up and down, so that the material blocking plate closes or opens the notch of the bearing positioning groove 43. When the bearing is about to enter the bearing positioning groove 43 from the bearing feeding channel 44, the material blocking plate closes the notch of the bearing positioning groove 43 to prevent the bearing from falling out of the bearing positioning groove 43 during movement; when the bearing follows the mounting plate to move toward the rotor, the material blocking plate can also limit the bearing to prevent it from falling; when the bearing contacts the rotor, the material blocking plate rises, and then the bearing can be pressed onto the rotor.

[0050] like Figure 7 As shown, the feeding channel 44 has a vertical channel 55 connected to the bearing storage tank and a horizontal channel 56 connected to the vertical channel 55.

[0051] Specifically, when the bearing is placed in the bearing storage trough, the bearing enters the vertical channel 55 from the bearing storage trough under the action of gravity. At this time, the pushing drive 45 drives the bearing push plate 46 to push the bearing out of the horizontal channel 56 for loading. After one bearing is pushed out, the bearing push plate 46 returns to reset, and the next bearing enters the horizontal channel 56.

[0052] Furthermore, a bearing slide 57 is arranged on the bearing receiving plate 41 in a downwardly inclined manner, and the feed end of the bearing slide 57 is located at the front end of the horizontal channel 56. The bearing can slide into the bearing positioning groove 43 through the bearing slide 57. The bearing is in a horizontal state when in the horizontal slide. After passing through the bearing slide 57, it can be vertically positioned in the bearing positioning groove 43, which is convenient for the subsequent pressing of the bearing.

[0053] like Figure 2 and Figure 8 As shown, the rotor processing device 2 also includes a guide slide 31 and a rotor lifting mechanism 32. When processing rotors of different models, it is necessary to adjust the height of the rotor so that its central axis coincides with the central axis of the bearing, so as to facilitate pressing the bearings on both ends of the rotor. The rotor is positioned in the rotor clamping mechanism 33, so the rotor lifting mechanism 32 is provided to adjust the height of the rotor clamping mechanism 33.

[0054] Specifically, both ends of the guide slide 31 are movably disposed on the movable mold guide rod 12 , the rotor lifting mechanism 32 is movably disposed on the guide slide 31 , and the rotor positioning seat 331 of the rotor clamping mechanism 33 is movably disposed on the rotor lifting mechanism 32 .

[0055] Furthermore, the rotor lifting mechanism 32 includes a lifting drive member 323, a lifting screw rod 324 and a lifting sleeve 325. The lifting drive member 323 is mounted on the guide slide 31; the lifting screw rod 324 passes through the rotor positioning seat 331 and is arranged at the output end of the lifting drive member 323; the lifting sleeve 325 is threadedly sleeved on the outside of the lifting screw rod 324 and is arranged in the rotor positioning seat 331; when the movable lifting screw rod 324 of the lifting drive member 323 rotates, since the lifting sleeve 325 is fixedly arranged on the rotor positioning seat 331, the rotor positioning seat 331 can be lifted and lowered by the threaded action between the lifting screw rod 324 and the lifting sleeve 325.

[0056] Furthermore, the lifting drive member 323 is fixedly arranged on the guide slide 31 through a plurality of lifting guide rods 322, and the rotor positioning seat 331 is movably arranged on the lifting guide rods 322. The lifting guide rods 322 can guide the movement of the rotor positioning seat 331 and increase its stability during lifting.

[0057] like Figure 2 and Figure 8 As shown, the rotor clamping mechanism 33 is arranged on a rotor positioning seat 331 , and a rotor positioning groove 332 for placing the rotor is opened on the rotor positioning seat 331 . When positioning the rotor, the rotor clamping mechanism 33 also rises and falls with the rotor positioning seat 331 .

[0058] Specifically, the rotor clamping mechanism 33 includes a clamping drive 333 and a rotor clamping member 334. The clamping drive 333 can drive the rotor clamping member 334 to rise and fall, and fix the rotor in the rotor positioning groove 332 to improve the stability when the bearing is pressed. The rotor clamping member 334 is movably arranged at the output end of the clamping drive 333, and is used to cooperate with the rotor positioning seat 331 to position the rotor in the rotor positioning groove 332 of the rotor positioning seat 331.

[0059] like Fig. 9 and Fig.10 As shown, the output end of the movable mold driving mechanism 23 is connected to the movable mold plate 22, which is used to push the movable mold plate 22 to move. The movable mold driving mechanism 23 includes a movable mold driving member 231, a transmission synchronous wheel 1 234, a transmission synchronous wheel 235, a transmission synchronous belt 237, a movable mold screw 233 and a screw shaft sleeve 238. The movable mold driving member 231 is arranged on a fixed plate, and its output end is connected to the transmission synchronous wheel 1 234. The transmission synchronous wheel 235 is arranged on the fixed plate through a transmission synchronous wheel base 236. The transmission synchronous wheel 1 234 can drive the transmission synchronous wheel 235 to rotate through the transmission synchronous belt 237. The screw shaft sleeve 238 is arranged on the transmission synchronous wheel 235, and a part of the movable part is arranged on the fixed plate. In the fixed plate, the front end of the movable mold screw 233 is fixedly connected to the movable mold plate 22, and the rear end passes through the fixed plate and is threadedly connected to the screw sleeve 238. Therefore, when the movable mold driving component 231 drives the transmission synchronous wheel 234 to rotate, the screw sleeve 238 rotates accordingly. Since the front end of the movable mold screw 233 is fixed and the rear end is threadedly connected to the screw sleeve 238, the screw sleeve 238 can drive the movable mold screw 233 to move horizontally to realize the movement of the movable mold plate 22. Through the transmission method between the synchronous wheel and the screw, the movable mold plate 22 can be pushed more accurately to stably press the bearing, and the bearing and rotor will not be damaged due to excessive press-fitting, and the bearing will not be unable to be press-fitted on the rotor due to insufficient pressure.

[0060] Furthermore, a pressure sensor 239 is provided between the front end of the movable mold screw 233 and the movable mold plate 22. The pressure sensor 239 can accurately determine the pressure. For a certain type of rotor and bearing, the pressure required for press-fitting the bearing is fixed during its processing. Therefore, whether the press-fitting is completed can be judged by observing the value of the pressure sensor 239.

[0061] The above shows and describes the basic principle and main features of the technical solution and the advantages of the technical solution. The technicians in this industry should understand that the technical solution is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the technical solution. Without departing from the spirit and scope of the technical solution, the technical solution will have various changes and improvements, which fall within the scope of the technical solution to be protected. The scope of protection claimed by the technical solution is defined by the attached claims and their equivalents.
