[0031] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 As shown, a rotor press-fitting device is used to press-fit bearing 1 and bearing 2 on both ends of a rotor, comprising: a processing frame 1, a rotor processing device 2, a rotor positioning device 3, a fixed die plate 21 and a movable die driving mechanism 23. The movable die driving mechanism 23 can drive the movable die plate 22 of the rotor processing device 2 and the rotor positioning device 3 to move toward the fixed die plate 21, and the bearing 1 and bearing 2 are respectively loaded on the movable die plate 22 and the fixed die plate 21, so as to realize the press-fitting of the bearings on both ends of the rotor.

[0033] Specifically, Figure 2As shown, the processing frame 1 has a processing platform, and a fixed plate 12 is arranged in the middle of the processing platform. The rotor processing device 2 and the movable mold driving mechanism 23 are respectively arranged on both sides of the fixed plate 12, the rotor positioning device 3 is arranged at the front end of the rotor processing device 2, and the fixed mold plate 21 is arranged at the front end of the rotor positioning device 3. 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 method can ensure that the bearings and the rotor have higher concentricity. Since the rotor positioning device 3 always supports the rotor horizontally, the stability of the bearings can also be ensured.

[0034] Furthermore, at least two movable mold guide rods 11 are arranged between the fixed mold plate 21 and the fixed plate 12, and the movable mold plate 22 is movably arranged on the movable mold guide rod 11. Both the fixed mold plate 21 and the fixed plate 12 are provided with a plurality of through holes for installing the movable mold guide rod 11. 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 11 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 11 is simpler and more practical.

[0035] Furthermore, two left and right protective gratings 43 are arranged on the processing frame 1, and the protective gratings 43 are respectively arranged at the front end of the fixed template 21 and the fixed plate 12. The protective gratings 43 are used to detect whether human hands are inserted into the equipment space. When the protective grating 43 detects the entry of human hands, the equipment cannot be started when the equipment start button is pressed to protect the safety of personnel.

[0036] 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.

[0037] like Figure 3 and Figure 4 As shown, the rotor positioning device 3 includes a guide slide 313, a rotor lifting mechanism 32 and a rotor clamping mechanism 33. 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.

[0038] Specifically, the rotor lifting mechanism 32 has at least a lifting base plate 321, a lifting drive module and a lifting screw 324. The lifting screw 324 is fixedly connected to the lifting base plate 321. The rotor clamping mechanism 33 is arranged on the lifting base plate 321. The lifting drive module can drive the lifting screw 324 to lift and lower, thereby realizing the height adjustment of the lifting base plate 321.

[0039] Furthermore, the lifting drive module includes a lifting drive member 323, a lifting synchronous wheel 1 325, a lifting synchronous wheel 2 326, a lifting synchronous belt 327, an active lifting shaft sleeve 328 and a driven lifting shaft sleeve 329. The lifting drive member 323 is arranged below the guide slide 313, and its output end is connected to the lifting synchronous wheel 1 325. The lifting synchronous wheel 2 326 is arranged below the guide slide 313 through the lifting synchronous wheel base 330. The lifting synchronous wheel 1 325 can drive the lifting synchronous wheel 326 through the lifting synchronous belt 327. The second lifting wheel 326 rotates, the active lifting sleeve 328 is set on the lifting synchronous wheel 326, the driven lifting sleeve 329 is threadedly connected to the outside of the lifting screw 324, and is partially movably set in the guide slide 313, the driven lifting sleeve 329 is set at the upper end of the active lifting sleeve 328, the lifting screw 324 is placed in the active lifting sleeve 328, but there is a gap from the inner wall of the active lifting sleeve 328, the active lifting sleeve 328 does not affect the movement of the lifting screw 324 while driving the driven lifting sleeve 329 to rotate.

[0040] Furthermore, the active lifting sleeve 328 and the passive lifting sleeve 329 may be provided as an integral structure.

[0041] The working principle of the lifting screw 324 transmitting the lifting base plate 321 is as follows: the lower end of the lifting screw 324 is threadedly connected to the lifting sleeve, and the upper end is fixedly connected to the lifting base plate 321. When the driven lifting sleeve 329 drives the lifting screw 324 to rotate, since the upper end of the lifting screw 324 is fixed, the driven lifting sleeve 329 can drive the lifting screw 324 to rise and fall, thereby realizing the lifting and lowering of the lifting base plate 321. Through the transmission method between the synchronous wheel and the screw, the rotor can be lifted and lowered more accurately to adapt to the position of the bearing, thereby improving the concentricity between the two.

[0042] like Figure 3 and Figure 4 As shown, the lifting base plate 321 is movably arranged on the guide slide 313 through a plurality of lifting guide rods 322. The lifting guide rods 322 can guide the movement of the lifting base plate 321 and increase its stability during lifting.

[0043] Furthermore, the rotor clamping mechanism 33 is arranged on the lifting base plate 321. When it positions the rotor, it also rises and falls with the lifting base plate 321. The rotor clamping mechanism 33 includes: a rotor positioning seat 331, which is arranged on the lifting base plate 321 and has a rotor positioning groove 332 for placing the rotor; a clamping drive member 333, which is arranged on the lifting base plate 321; and a rotor clamping member 334, which is movably arranged at the output end of the clamping drive member 333 and is used to cooperate with the rotor positioning seat 331 to position the rotor in the rotor positioning groove 332. The clamping drive member 333 can drive the rotor clamping member 334 to rise and fall, and fix the rotor in the rotor positioning groove 332, so as to improve the stability when the bearing is pressed.

[0044] like Figure 3 As shown, when the movable platen 22 and the rotor positioning device 3 move toward the fixed platen 21, the rotor positioning device 3 needs to follow the movement, so a rotor guide mechanism 31 is arranged on the processing frame 1, which comprises: two guide rails 311, which are arranged on the processing frame 1; and two guide sliders 312, which are respectively arranged on the two guide rails 311, and the guide slide 313 is arranged on the two guide sliders 312.

[0045] like Figure 6 and Figure 7 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 1 235, a transmission synchronous wheel 236, a transmission synchronous belt 237, a movable mold screw 233, an active screw shaft sleeve 238 and a driven screw shaft sleeve 239. The movable mold driving member 231 is arranged on the fixed plate 12, and its output end is connected to the transmission synchronous wheel 1 235. The transmission synchronous wheel 236 is arranged on the fixed plate 12 through the transmission synchronous wheel base 234. The transmission synchronous wheel 1 23 The second transmission synchronous wheel 236 can be driven to rotate by the transmission synchronous belt 237. The active screw shaft sleeve 238 is arranged on the second transmission synchronous wheel 236. The driven screw shaft sleeve 239 is threadedly connected to the outside of the movable mold screw 233 and is partially movably arranged in the fixed plate 12. The driven screw shaft sleeve 239 is arranged on the upper end of the active screw shaft sleeve 238. The movable mold screw 233 is placed in the active screw shaft sleeve 238, but there is a gap between the active screw shaft sleeve 238 and the inner wall of the active screw shaft sleeve 238. The active screw shaft sleeve 238 does not affect the movement of the movable mold screw 233 while driving the driven screw shaft sleeve 239 to rotate.

[0046] Furthermore, the active screw shaft sleeve 238 and the driven screw shaft sleeve 239 can be provided as an integral structure.

[0047] The working principle of the movable mold screw 233 driving the movable mold plate 22 is: 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 12 and is threadedly connected to the driven screw sleeve 239. When the driven screw sleeve 239 drives the mold screw 233 to rotate, since the front end of the movable mold screw 233 is fixed, the driven screw sleeve 239 can drive the movable mold screw 233 to move horizontally, thereby realizing 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, so that the bearing can be stably pressed into the bearing, and the bearing and rotor will not be damaged due to excessive pressing, and the bearing will not be pressed into the rotor due to insufficient pressure.

[0048] like Figure 5 As shown, a buffer reset rod 4 is passed through the movable template 22, the front end of the buffer reset rod 4 is connected to the guide slide 313, the rear end passes through the fixed plate 12 and is movably connected to the other side of the fixed plate 12, the front end and rear end of the buffer reset rod 4 are respectively sleeved with a buffer reset spring 1 41 and a buffer reset spring 2 42, the two ends of the buffer reset spring 1 41 are respectively connected to the guide slide 313 and the movable template 22, and the two ends of the buffer reset spring 2 42 are respectively connected to the movable template 22 and the fixed plate 12.

[0049] Furthermore, when the equipment is working in an initial non-working state, the buffer reset spring 41 is compressed, which buffers the force of the bearing being pressed onto the rotor, slows down the movement speed of the movable template 22 toward the guide slide 313, and improves the stability of the bearing press; at this time, the movable template 22 moves away from the fixed plate 12, and the buffer reset spring 42 is stretched. When the bearing press is completed, the buffer reset spring 42 can pull the movable template 22 back to reset and play a role in buffering reset.

[0050] like Figure 6 As shown, a pressure sensor 240 is provided between the front end of the movable mold screw 233 and the movable mold plate 22. The pressure sensor 240 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 240.

[0051] 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.
