[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1: like Figures 1 to 8 As shown, the first embodiment of the present invention provides a rotor shell magnetic steel inserting machine, including a base 24, a positioning seat 1 and a feed assembly, the feed assembly includes a feed tray 4 and a push cylinder 5, wherein four fixing columns 25 are fixed on the base 24, the feed tray 4 is fixed on the fixing columns 25, and the positioning seat 1 is fixed on the feed tray 4. Figure 2 and Figure 3 As shown, since the rotor shell 3 is cylindrical, an annular positioning groove 2 is provided on the positioning seat 1 for placing the rotor shell 3. In the present invention, the magnetic steel 7 enters the interior of the rotor shell 3 from the bottom of the rotor shell 3, so a clearance hole penetrating the positioning seat 1 is provided in the positioning groove 2, so that the push cylinder 5 can pass through the positioning seat 1 from the clearance hole.

[0027] The axis of the feed tray 4 and the positioning seat 1 are in line. In order to allow the push cylinder 5 to push the magnetic steel 7 on the feed tray 4 into the rotor housing 3, the push cylinder 5 must also be able to move on the feed tray 4. Therefore, a through hole for the push cylinder 5 to pass through is opened in the middle of the feed tray 4. Figure 2 and Figure 3 As shown, the feed tray 4 is provided with sixteen evenly distributed annular feed slots 6, each of which is provided with a pushing mechanism for pushing the magnetic steel 7 placed in the feed slot 6 to the pushing cylinder 5, and when the pushing cylinder 5 moves up and down, the magnetic steel 7 in the feed slot 6 can be lifted one by one to the inner side of the rotor shell 3. Figure 1 As shown, a first electric telescopic rod 26 can be fixed on the base 24, and the movable end of the first electric telescopic rod 26 is fixedly connected to the bottom of the pushing cylinder 5, so that the first electric telescopic rod 26 can control the lifting and lowering of the pushing cylinder 5 on the feed tray 4.

[0028] The pushing mechanism designed in the present invention comprises a push plate 22 slidably mounted in the feed trough 6 and a plug 28 fixed at one end of the feed trough 6 away from the push cylinder 5, and the plug 28 is connected to the push plate 22 by a spring 23. The spring 23 has elastic potential energy to push the push plate 22 toward the push cylinder 5. Under the action of the spring 23, the push plate 22 can push the magnetic steel 7 toward the push cylinder 5.

[0029] like Figure 7 As shown, sixteen dividing ribs 18 are evenly fixed on the circumferential outer wall of the push tube 5 of the present invention, and a push portion 8 is fixed on the push tube 5 between two adjacent dividing ribs 18. The push portion 8 is a boss 9 fixed on the lower outer wall of the cylinder body of the push tube 5. A push block 10 is arranged above the boss 9, and the push block 10 and the push tube 5 are slidably matched. Figure 3 and Figure 4 As shown, the sliding direction of the push block 10 is the diameter direction of the push tube 5. A supporting portion 11 that fits the boss 9 is fixed to the bottom of the push block 10. The push block 10 and the supporting portion 11 are L-shaped as a whole.

[0030] like Figure 5 As shown, a glue coating mechanism is also provided inside the push tube 5. The glue coating mechanism includes a rotating rod 19 rotatably mounted inside the push tube 5 and two nozzles 21 connected to the top of the rotating rod 19. A gear can be fixed on the rotating rod 19, and then a motor can be fixed on the inner wall of the push tube 5. When the motor drives the gear to rotate, the rotating rod 19 can be driven to rotate, and a flow channel 20 is provided inside the rotating rod 19. The bottom of the rotating rod 19 can be connected to the glue supply device using a rotary joint. The top of the rotating rod 19 extends out of the push tube 5. When the push tube 5 rises, the motor rotates, and the nozzle 21 rotates around the rotating rod 19. The glue supply device supplies glue to the nozzle 21 through the rotary joint and the flow channel 20, and the glue is sprayed from the nozzle 21 to the inner wall of the rotor shell 3.

[0031] In the initial state, the magnetic steel 7 is pushed against the side of the boss 9 by the push plate 22. As the push cylinder 5 descends in the through hole, the boss 9 also descends until the height of the boss 9 and the supporting portion 11 is lower than the magnetic steel 7. At this time, the magnetic steel 7 can be pushed against the supporting portion 11 and against the push block 10 by the push plate 22. When the push cylinder 5 rises, the magnetic steel 7 located on the supporting portion 11 is pushed upward by the supporting portion 11, thereby detaching from the feed trough 6, and the positioning seat 1 can resist the adjacent magnetic steel 7 on the side of the magnetic steel 7 away from the push block 10, ensuring that the supporting portion 11 pushes only one magnetic steel 7. As the push cylinder 5 rises, the nozzle 21 completes the glue spraying on the inner wall of the rotor shell 3 during rotation, and stops spraying when the nozzle 21 is about to extend out of the rotor shell 3. At this time, the supporting part 11 delivers the magnet 7 completely to the inner side of the rotor shell 3, and then the pressing mechanism arranged in the pushing cylinder 5 pushes the magnet 7 toward the inner wall of the rotor shell 3, so that the magnet 7 is adhered to the inner wall of the rotor shell 3, and the installation of the magnet 7 is completed.

[0032] Embodiment 2: On the basis of the first embodiment, the pressing mechanism designed by the present invention includes sixteen push rods 12, and the sixteen push rods 12 correspond to sixteen push blocks 10 respectively. Figures 3 to 6 As shown, each push rod 12 is slidably inserted on the side wall of the cylinder body of the push cylinder 5, and the push block 10 is fixed to the end of the push rod 12. The push rod 12 is perpendicular to the axis of the push cylinder 5. One end of the push rod 12 located inside the push cylinder 5 is fixed with two levers 16 perpendicular to the push rod 12. The pressing mechanism also includes a driving ring 13 slidably mounted on the inner wall of the push cylinder 5, and a plurality of driving plates 14 are fixed on the driving ring 13, each driving plate 14 corresponds to a lever 16, and a driving groove 15 is opened on the driving plate 14, and the lever 16 is limited in the driving groove 15.

[0033] Combination Figure 4 and Figure 6 It can be seen that when the driving ring 13 rises in the pushing cylinder 5, the driving plate 14 drives the lever 16 to move toward the inner wall of the rotor shell 3 through the driving groove 15, so that the push rod 12 pushes the push block 10 and presses the magnet 7 against the inner wall of the rotor shell 3. When the driving ring 13 descends in the pushing cylinder 5, the push rod 12 moves toward the axis of the pushing cylinder 5, thereby resetting the push block 10.

[0034] like Figure 1 As shown, a second electric telescopic rod 27 can be fixed at the bottom of the pushing cylinder 5 through a bracket, and the movable end of the second electric telescopic rod 27 is fixed to the driving ring 13 through a connecting rod, so that the second electric telescopic rod 27 can control the driving ring 13 to rise and fall in the pushing cylinder 5.

[0035] Embodiment three: Based on the second embodiment, Figure 6 As shown, an air suction hole 17 can be opened on the push block 10, and the push rod 12 can be set as a hollow rod, the inner cavity of the push rod 12 is connected to the air suction hole 17, and the end of the push rod 12 away from the air suction hole 17 is connected to an external air pump.

[0036] In this way, when the push plate 22 pushes the magnet 7 against the push block 10, the external air pump can make the suction hole 17 in a negative pressure, thereby adsorbing the magnet 7 on the push block 10. This ensures that the magnet 7 will not shift on the support part 11 during the upward movement of the push cylinder 5; when the push rod 12 moves, the magnet 7 will not shift on the support part 11. After the push block 10 pushes the magnet 7 against the inner wall of the rotor shell 3, the external air pump makes the suction hole 17 in a normal air pressure state, releasing the fixed relationship between the magnet 7 and the push block 10.

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
