DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-6 This application is described in further detail.

[0023] A rotor flatness selection mechanism, such as Figure 3 and Figure 4 As shown, it includes a frame 4 and a positioning platform 5. The positioning platform 5 is fixedly arranged in the middle of the frame 4. A positioning arc groove 6 adapted to the surface of the rotor 1 is arranged on the top of the positioning platform 5. The positioning arc groove 6 is used to improve the stability of the placement of the rotor 1. A feeding assembly 7 is arranged on one side of the frame 4. A flat square positioning sleeve 8 and a driving source 9 are arranged on the other side of the frame 4. The driving source 9 is used to drive the flat square positioning sleeve 8 to rotate. The flat square positioning sleeve 8 and the rotor 1 placed on the positioning platform 5 are axially colinearly arranged. The flat square positioning sleeve 8 is used to be plugged and adapted with the flat position 2 at one end of the rotor 1. The feeding assembly 7 is used to axially push the rotor 1 to move so that its end is inserted into the flat square positioning sleeve 8.

[0024] like Figure 3 and Figure 4 As shown, the feed assembly 7 includes a feed ejector pin 10, a seat body 11 and a feed cylinder 12. The feed ejector pin 10 is axially adjustably mounted on the seat body 11. The seat body 11 is horizontally slidably connected to the frame 4 along the axial direction of the flat square positioning sleeve 8. The frame 4 is provided with a guide rail 13 that slides with the seat body 11. The piston rod end of the feed cylinder 12 is fixed on the seat body 11 to drive it to move horizontally axially. The feed cylinder 12 is arranged parallel to the guide rail 13, which effectively shortens the overall axial length of the structure, so that the overall length of the frame 4 can be shorter and the structure is more compact.

[0025] like Figure 3 and Figure 5As shown, the driving source 9 includes a driving motor 14 and a transmission component, and the transmission component includes a transmission box 15, a synchronous wheel 16 and a synchronous belt 17. The synchronous wheel 16 is rotatably connected in the transmission box 15. The two synchronous wheels 16 are connected through the synchronous belt 17. One of the synchronous wheels 16 is installed on the output shaft of the driving motor 14, and the other synchronous wheel 16 is connected to the flat square positioning sleeve 8 to realize the flat square positioning sleeve 8 being rotatably connected to the transmission box 15. In this way, starting the driving motor 14 can drive the flat square positioning sleeve 8 to rotate to achieve the position adjustment of the flat position 2 on the rotor 1.

[0026] like Figure 3 , Figure 4 and Figure 6 As shown, a directional detection member 18 is fixedly provided on the transmission box 15 of the driving source 9, and a first sensing portion 19 for matching with the directional detection member 18 is provided on the flat square positioning sleeve 8. When the directional detection member 18 senses the first sensing portion 19 on the flat square positioning sleeve 8, it represents that the state of the flat position 2 on the lower rotor 1 is correct. At this time, the driving motor 14 can stop the flat square positioning sleeve 8 to complete the position adjustment of the flat position 2 on the rotor 1. In this embodiment, the directional detection member 18 adopts a directional proximity switch, and the first sensing portion 19 is a first protrusion protruding from the outer wall of the flat square positioning sleeve 8. When the first protrusion corresponds to the directional proximity switch, the directional proximity switch can sense the current position state.

[0027] like Figure 3 and Figure 4 As shown, a base 20 is fixedly provided at the bottom of the transmission box 15, and the base 20 is connected to the frame 4 along the axial sliding of the flat square positioning sleeve 8. At the same time, a fixed block 21 is provided on the frame 4, and a reset member 22 for driving the driving source 9 to axially move and reset is provided on the fixed block 21. The reset member 22 specifically adopts a reset spring, one end of the reset spring is connected to the fixed block 21, and the other end is connected to the base 20. A support shaft for supporting the reset spring is passed through the reset spring, and the reset spring is always in a compressed state. The reset spring is used to drive the flat square positioning sleeve 8 to reset to a plug-in fit with the end of the rotor 1.

[0028] like Figure 3 , Figure 4 and Figure 6As shown, a flat square selection detection member 23 is provided on the frame 4, and a second sensing portion 24 for matching with the flat square selection detection member 23 is provided on the flat square positioning sleeve 8. The first sensing portion 19 and the second sensing portion 24 are arranged relatively on the flat square positioning sleeve 8. The flat square selection detection member 23 adopts a flat square selection proximity switch, and the second sensing portion 24 is a second protrusion protruding from the outer wall of the flat square positioning sleeve 8. Whether the end of the rotor 1 is plugged into the flat square positioning sleeve 8 is judged by whether the flat square selection detection member 23 senses the second sensing portion 24. When the end flat square position 2 of the rotor 1 in the initial placement state does not correspond to the flat square positioning sleeve 8, the feeding component 7 drives the rotor 1 to move axially through During the rotation process, the rotor 1 will synchronously push the flat square positioning sleeve 8 and the driving source 9 to move horizontally, the reset spring will be further compressed, and the driving motor 14 will drive the flat square positioning sleeve 8 to rotate until it matches the end of the rotor 1 with the flat position 2. Under the action of the reset spring, the flat square positioning sleeve 8 will axially move and reset to be plugged and adapted with the end of the rotor 1. At this time, the flat square selection detection piece 23 can sense that the second sensing part 24 represents that the end of the rotor 1 has been inserted into the flat square positioning sleeve 8. During the synchronous rotation of the flat square positioning sleeve 8 and the rotor 1, the flat position 2 on the rotor 1 is adjusted with the help of the directional detection piece 18 and the first sensing part 19. During this period, no matter how the rotor 1 is placed in the initial state, the deviation correction can be automatically achieved.

[0029] like Figure 3 and Figure 4 As shown, a material return assembly 25 is arranged on the frame 4, and the material return assembly 25 includes a material return ejector pin 26 and a material return cylinder 27. The material return ejector pin 26 is inserted into the flat square positioning sleeve 8 and is arranged colinearly with the center thereof. The material return cylinder 27 drives the material return ejector pin 26 to move axially horizontally. After completing the adjustment of the flat position 2 on the rotor 1, the material return ejector pin 26 can be driven by the pushing cylinder to move the end of the rotor 1 out of the flat square positioning sleeve 8. At this time, the rotor 1 can be directly taken vertically, which is convenient for the robot to automatically clamp the rotor 1 later, and realize automatic pushing of the rotor 1, which is more convenient and quick.

[0030] like Figure 3-Figure 5 As shown, a positioning plate 28 is fixedly provided on the frame 4, and a positioning member 29 and a buffer 30 are provided on the positioning plate 28. The positioning member 29 is a positioning bolt threadedly connected to the positioning plate 28, and the axial direction of the positioning bolt is consistent with the moving direction of the driving source 9. The end of the positioning bolt is used to abut against the end face of the base 20 away from the reset member 22. The buffer 30 is arranged in parallel with the positioning member 29, and the end of the buffer 30 is closer to the end face of the base 20 than the end of the positioning member 29. The rotation adjustment of the positioning member 29 can realize the adjustment of the initial position of the flat square positioning sleeve 8, so that it can be applicable to rotors 1 models of different specifications, thereby improving applicability. In addition, the design of the buffer 30 can play a good buffering role in the movement and reset of the driving source 9 to avoid severe impact.

[0031] like Figure 3 and Figure 4 As shown, a lifting seat 31 is arranged on both sides of the frame 4 corresponding to the positioning platform 5, and an induction switch is installed on the lifting seat 31. The induction switch includes a transmitting end 32 and a receiving end 33. The transmitting end 32 and the receiving end 33 are respectively located on the opposite sides of the positioning platform 5. The induction switch is used to sense whether there is a rotor 1 placed on the positioning platform 5. The use of the control system facilitates the automatic control of the flat square selection of the rotor 1; wherein the lifting seat 31 includes a fixed column 34 and a clamping seat 35, the clamping seat 35 is sleeved on the fixed column 34 and is clamped on the fixed column 34 by bolts. The vertical position of the clamping seat 35 can be adjusted by loosening the bolts. In this embodiment, the flat square selection detection member 23 is also installed on the lifting seat 31 to achieve height adjustment, so that it can be suitable for more rotors 1 of different specifications, effectively improving applicability.

[0032] The working principle of the embodiment of the present application is as follows: first, it is placed on the positioning table 5 by a robot or manually. After the induction switch detects the rotor 1, the feeding cylinder 12 of the feeding assembly 7 is actuated, driving the feeding ejector 10 to push the rotor 1 forward. At this time, when the flat position 2 of the rotor 1 and the flat square positioning sleeve 8 are not aligned, the rotor 1 pushes the flat square positioning sleeve 8 and the driving source 9 to move to the left, compressing the reset spring, and the driving motor 14 drives the flat square positioning sleeve 8 to rotate through the synchronous belt 17. At this time, the rotor 1 does not rotate. When the flat square positioning sleeve 8 rotates to align with the flat position 2 of the rotor 1, the flat square positioning sleeve 8 moves forward under the elastic force of the reset spring, and the flat position 2 of the rotor 1 enters the flat square positioning sleeve 8, and the rotor 1 starts to rotate. At this time, the second sensing part 24 on the flat square positioning sleeve 8 has the same axial position as the flat square selection detection part 23. When the two coincide, the flat square selection detection part 23 detects a signal, which indicates that the flat direction 2 of the rotor 1 is inserted into the flat square positioning sleeve 8 and continues to rotate. When the first sensing part 19 on the flat square positioning sleeve 8 coincides with the directional detection part 18, the drive motor 14 stops rotating immediately, the flat direction 2 of the rotor 1 is selected, and the material return cylinder 27 of the material return assembly 25 is actuated to push the rotor 1 out of the flat square positioning sleeve 8, and the flat square selection action is completed.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
