[0047] As shown in the figure, a rotor bearing assembly system comprises a workbench 1, a rotor support seat 2 is arranged on the workbench 1, the rotor support seat 2 is driven to move horizontally and linearly by a rotor seat driving mechanism 5, a rotor feeding mechanism 3 is arranged at the end of the horizontal linear movement extension line of the rotor seat driving mechanism 5, rotor bearing stacking and output devices 4 of the same specification are arranged on both sides of the rotor seat driving mechanism 5 respectively, which are respectively used to output a rotor small bearing 9 to the rotor support seat 2 and a rotor large bearing 10 to the directly above of the rotor support seat 2; further comprising a rotor bearing pressing device 6 arranged above the rotor seat driving mechanism 5, which can press-connect a rotor 11 with the rotor small bearing 9 and the rotor large bearing 10 respectively. Figures 1-3 The purpose of the system is to press-fit a rotor large bearing 10 and a rotor small bearing 9 to the upper and lower ends of a rotor 11 respectively, wherein the rotor small bearing 9 is located at the lower end of the rotor 11 and the rotor large bearing 10 is located at the upper end of the rotor 11.

[0048] As a further description of the system, the rotor bearing stacking and output devices 4 comprise a first rotor bearing stacking and output device 41 and a second rotor bearing stacking and output device 42 (since the second rotor bearing stacking and output device 42 is used to provide a rotor large bearing 10 to the top end of the rotor 11, it needs to be lifted by a large bearing support 440), the first rotor bearing stacking and output device 41 outputs the rotor small bearing 9 to the rotor support seat 2 through a small bearing driving mechanism 43; the second rotor bearing stacking and output device 42 outputs the rotor large bearing 10 to the directly above of the rotor support seat 2 through a large bearing driving mechanism 44.

[0049]

[0050] ​The rotor bearing pressing device 6 comprises a rotor bearing support 61 vertically connected with the workbench 1, a small bearing pressing cylinder 62 and a large bearing pressing cylinder 63 are arranged on the rotor bearing support 61, a small bearing pressing rod 64 vertically downward is connected with the piston end of the small bearing pressing cylinder 62, and a large bearing pressing rod 65 vertically downward is connected with the piston end of the large bearing pressing cylinder 63.

[0051] In the embodiment, a rotor conveying belt 7 is arranged along the side edge of the workbench 1, and a rotor carrier 8 is arranged on the rotor conveying belt 7, which is used to provide an unassembled rotor for the rotor feeding mechanism 3 and to store and convey the assembled rotor.

[0052] Working principle:

[0053] Firstly, the rotor seat driving mechanism 5 drives the rotor support seat 2 to be directly below the small bearing pressing rod 64 of the rotor feeding mechanism 3, at this time, the first rotor bearing stacking and output device 41 outputs the rotor small bearing 9 to the rotor support seat 2 through the small bearing driving mechanism 43.

[0054] Then, the rotor feeding mechanism 3 clamps the rotor conveyed on the rotor carrier 8, and moves the rotor 11 to the rotor support seat 2 in a rotary feeding mode, at this time, the rotor small bearing 9 is located below the rotor 11; the small bearing pressing cylinder 62 drives the small bearing pressing rod 64 to press the rotor 11 and the rotor small bearing 9 at the lower end.

[0055] After the pressing is completed, the rotor seat driving mechanism 5 drives the rotor support seat 2 loaded with the rotor 11 to be directly below the large bearing pressing rod 65, and the large bearing pressing cylinder 63 drives the large bearing pressing rod 65 to press the rotor large bearing 10 magnetically attracted at the end to the top end of the rotor 11.

[0056] After the pressing is completed, the rotor seat driving mechanism 5 drives the assembled rotor 11 to be directly below the small bearing pressing rod 64, and the rotor feeding mechanism 3 clamps and takes away the assembled rotor 11.

[0057] The above steps are repeated to realize the purpose of automatically assembling the rotor 11 with the rotor large bearing 10 and the rotor small bearing 9.

[0058] In order to speed up the feeding and taking efficiency and save unnecessary idle time, the rotor feeding mechanism 3 in the embodiment adopts a double-claw form, that is, feeding and taking are carried out at the same time, which can effectively increase the assembly efficiency, and the specific implementation is as follows:

[0059] For example, Figure 4 and 7As shown, the rotor feeding mechanism 3 includes a feeding rotary cylinder 31 arranged at the bottom of the workbench 1, the rotating shaft of the feeding rotary cylinder 31 penetrates the workbench 1 and is connected with a feeding rotary seat 32, a feeding support 33 is vertically connected on the feeding rotary seat 32, a I-shaped feeding clamp connecting seat 34 capable of vertically lifting relative to the feeding support 33 is arranged on the feeding support 33, and a first cylinder clamp jaw 35 and a second cylinder clamp jaw 36 symmetrically arranged at both ends of the feeding clamp connecting seat 34 are arranged at both ends of the feeding clamp connecting seat 34; the feeding clamp connecting seat 34 is driven by a feeding push rod cylinder 37 arranged on the feeding support 33.

[0060] In the above working principle, namely:

[0061] Firstly, the rotor seat driving mechanism 5 drives the rotor support seat 2 to be right below the small bearing pressing rod 64 of the rotor feeding mechanism 3, at this time, the first rotor bearing stacking and output device 41 outputs the rotor small bearing 9 to the rotor support seat 2 through the small bearing driving mechanism 43;

[0062] Then, the first cylinder clamp jaw 35 of the rotor feeding mechanism 3 clamps the rotor 11 conveyed on the rotor carrier 8, and the second cylinder clamp jaw 36 of the rotor feeding mechanism 3 clamps the rotor 11 already assembled on the rotor support seat 2; the second cylinder clamp jaw 36 clamps the rotor 11 already assembled on the rotor support seat 2 and moves it to the rotor carrier 8 by rotating 180°, and the first cylinder clamp jaw 35 clamps the rotor 11 conveyed on the rotor carrier 8 and moves it to the rotor support seat 2; at this time, the rotor small bearing 9 is below the rotor 11; the small bearing pressing cylinder 62 drives the small bearing pressing rod 64 to press the rotor 11 and the rotor small bearing 9 at the lower end;

[0063] After the pressing is completed, the rotor seat driving mechanism 5 drives the rotor support seat 2 carrying the rotor 11 to be right below the large bearing pressing rod 65, and the large bearing pressing cylinder 63 drives the large bearing pressing rod 65 to press the end-magnetically-attracted rotor large bearing 10 to the top end of the rotor 11.

[0064] After the pressing is completed, the rotor seat driving mechanism 5 drives the rotor 11 after assembly to be right below the small bearing pressing rod 64, the second cylinder clamp jaw 36 clamps the rotor 11 already assembled on the rotor support seat 2 and moves it to the rotor carrier 8, and at the same time, the first cylinder clamp jaw 35 clamps the rotor 11 conveyed on the rotor carrier 8 and moves it to the rotor support seat 2.

[0065] The above steps are repeated to realize the purpose of automatically assembling the rotor 11 with the rotor large bearing 10 and the rotor small bearing 9.

[0066] As Figure 6 and7 As shown, as the optimization of the rotor seat driving mechanism 5 in the present embodiment, the rotor seat driving mechanism 5 comprises a set of mutually symmetrical rotor seat sliding rails 52 arranged on the surface of the workbench 1, rotor seat sliding blocks 51 matched with the rotor seat sliding rails 52 are arranged on the rotor seat sliding rails 52, rotor support seat bottom plates 53 are connected to the rotor seat sliding blocks 51, the rotor support seats 2 are arranged on the rotor support seat bottom plates 53; rotor support seat push plates 54 are arranged along the outer sides of the rotor support seat bottom plates 53, the rotor support seat push plates 54 are connected with the push rods of rotor seat driving cylinders 55; the rotor seat driving cylinders 55 are connected with the workbench 1.

[0067] The rotor support seat 2 comprises small bearing support seats 56 connected with the rotor support seat bottom plates 53, and C-shaped rotor support sleeves 57 which can be sleeved on the small bearing support seats 56, the top of the C-shaped rotor support sleeve 57 is provided with a rotor through slot 58 into which the bottom end of the rotor 11 can be inserted, a small bearing inlet 59 is arranged on one side of the small bearing support seat 56, and small bearing guide sliding grooves 510 corresponding to the small bearing inlet 59 are arranged on the rotor support seat bottom plate 53.

[0068] Since the press-fitting process of the rotor 11 is completed on the rotor support seat 2, the rotor 11 will inevitably be embedded in the rotor through slot 58 of the rotor support seat (i.e. the rotor 11 will descend by a distance), in order to facilitate the quick removal of the assembled rotor 11, the present embodiment is provided with a rotor guide-out mechanism on the workbench 1, which is used to push the assembled rotor 11 out of the rotor support seat 2 by a distance, i.e. to separate the rotor 11 from the rotor through slot 58, so as to facilitate the removal of the cylinder clamping jaw.

[0069] Specifically, a vertical hole 511 is arranged at the axial position of the rotor support seat 2, a guide seat 66 is further arranged on the workbench 1 corresponding to the position directly below the small bearing press rod 64, a rotor ejection rod through hole 67 is arranged at the axial position of the guide seat 66, and a rotor ejection rod driving cylinder 68 is arranged on the bottom surface of the workbench 1 corresponding to the rotor ejection rod through hole 68, a rotor ejection rod 69 which can sequentially penetrate the workbench 1, the rotor ejection rod through hole 68 and the vertical hole 511 is connected to the piston rod of the rotor ejection rod driving cylinder 68, and the rotor ejection rod 69 can act on the bottom end of the rotor 11.

[0070] As shown in FIG. 6, the rotor 11 is assembled on the rotor support seat 2, and the rotor 11 is embedded in the rotor through slot 58 of the rotor support seat 2. Figure 8 And 9As shown, the rotor bearing stacking and output device 4 comprises a belt conveying line 45 capable of conveying rotor bearings (in this embodiment, the belt conveying line 1 is controlled by a motor 439), symmetrical baffles 49 are arranged on both sides of the belt conveying line 45, a feeding recess 410 is formed on any one of the baffles 49, a pushing module 46 connected with the feeding recess 410 is arranged at the feeding recess 410, and a stacking module 47 is arranged on the pushing module 46, which can push the rotor bearings longitudinally stacked on the stacking module 47 one by one to the belt conveying line 45.

[0071] Working principle:

[0072] The rotor bearings requiring output assembly are stacked by the stacking module 47. Since the rotor bearings are longitudinally stacked, they will always fall into the pushing module 46 due to gravity, and the pushing module 46 pushes the rotor bearings falling into the feeding recess 410 to the belt conveying line 45, achieving the purpose of pushing and outputting one by one.

[0073] As shown in Figure 9 and 10 , the pushing module 46 in this embodiment comprises a feeding base 432 matched with the feeding recess 410, a plurality of blocking bars 433 are arranged on the feeding base 432, a pushing sliding groove 435 capable of translating a pushing sliding block 434 is formed between adjacent blocking bars 433, the pushing sliding block 434 is connected with a piston of an electric push rod 436, and the electric push rod 436 is connected with the feeding base 432 through a support 437.

[0074] Among them, the discharge port of the pushing sliding groove 435 corresponds to the feeding recess 410, and the pushing sliding groove 435 is horizontal with the surface of the belt 48 on the belt conveying line 45;

[0075] In order to facilitate the smooth penetration of the rotor bearings, the height of the pushing sliding groove 435 is greater than the height of the rotor bearings; and the width of the pushing sliding groove 435 is not less than the outer diameter of the rotor bearings.

[0076] As shown in Figure 9 and 11 , the stacking module 47 in this embodiment comprises a stacking base 425 arranged on the blocking bars 433 and the top of the pushing sliding groove 435, a plurality of material guiding through holes 426 are formed on the stacking base 425, and each material guiding through hole 426 corresponds to the pushing sliding groove 435 below.

[0077] It also includes a top plate 427, which is supported by a pair of symmetrical pillars 428 between the top plate 427 and the material stacking base 425. The top plate 427 is also provided with material stringing columns 429 corresponding to the number of material inlet holes 426 and perpendicular to the material inlet holes 426. The material stringing columns 429 are used for the rotor bearing to be sleeved.

[0078] To ensure that the rotor bearings mounted on the feed column 429 can accurately enter the pusher groove 435, the bottom end of the feed column 429 needs to be placed inside the feed through hole 426 and perpendicular to the center of the feed through hole 426.

[0079] In this embodiment, the material stacking base 425 is rectangular, with its side corresponding to the feeding groove 410. This structure ensures that the material stacking base 425 and the pushing slide 435 form a sealed U-shaped discharge port, which can effectively prevent the rotor bearing from shifting due to the impact of the pushing slide 434.

[0080] The material stacking base 425 is connected to the stop bar 433 by screws.

[0081] like Figure 12 As shown, in order to monitor the status of the rotor bearing on the material stacking module 47 in real time, this embodiment also provides a number of sensors 430 corresponding to the number of material stacks 429 along the adjacent position of the material stacking base 425. The sensors 430 are used to detect the material stacking status on the material stacks 429.

[0082] The sensor 430 is connected to the material stacking base 425 via the sensor connecting plate 431.

[0083] like Figure 5 As shown, in this embodiment, the first rotor bearing stacking and output device 41 outputs the rotor small bearing 9 to the rotor support seat 2 through the small bearing drive mechanism 43;

[0084] The second rotor bearing stacking and output device 42 outputs the rotor large bearing 10 to the top of the rotor support 2 through the large bearing drive mechanism 44.
