DETAILED DESCRIPTION

[0019] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1 to 4 The utility model provides a technical solution: a rotor core magnetic steel insertion device, comprising: a work platform 1, a top seat 2 and a rotor core 4, the top seat 2 is arranged above the work platform 1, and a plurality of reserved holes 5 are opened on the surface of the rotor core 4, the top of the work platform 1 is fixed with a base 3, and the bottom end of the work platform 1 is fixed with a second hydraulic tappet mechanism 15, and a plurality of pushing holes 7 are opened on the surface of the work platform 1, and a pushing plate 16 is fixed to the top of the tappet of the second hydraulic tappet mechanism 15, and a plurality of pushing pieces 8 are fixed to the top of the pushing plate 16, and the plurality of pushing pieces 8 are movably inserted in the plurality of pushing holes 7 respectively, and a plurality of magnetic steel grooves 22 are opened on the surface of the base 3, and magnetic steel 12 is arranged in the magnetic steel grooves 22, and the plurality of reserved holes 5, magnetic steel grooves 22 and pushing holes 7 are distributed up and down.

[0021] When the rotor core magnet insertion device is actually used, the rotor core 4 is placed on the top of the base 3 set at the top of the workbench 1, so that the several groups of reserved holes 5 on the surface of the rotor core 4 are aligned with the several groups of magnetic steel grooves 22 opened on the surface of the base 3, and then the magnets 12 are installed into each group of magnetic steel grooves 22. Finally, the distance that the push rod of the second hydraulic push rod mechanism 15 extends from the hydraulic cylinder becomes longer, so that the push plate 16 moves upward. The movement of the push plate 16 causes the top of each group of push plates 8 to extend from the top of the push hole 7, thereby pushing each group of magnetic steel 12 upward, so that each group of magnetic steel 12 is pushed into each group of reserved holes 5 at the same time, thereby greatly improving the efficiency of inserting magnets into the rotor core.

[0022] Example 2: Based on Example 1, in order to prevent the rotor core 4 from being pushed upward when inserting the magnet, a first hydraulic tappet mechanism 13 is provided on the surface of the top seat 2. The tappet of the first hydraulic tappet mechanism 13 is movably inserted on the surface of the top seat 2, and a clamping plate 14 is fixed to the bottom end of the tappet of the first hydraulic tappet mechanism 13.

[0023] After the rotor core 4 is placed on the top of the base 3, the tappet of the first hydraulic tappet mechanism 13 fixed on the surface of the top seat 2 is extended further from the hydraulic cylinder, so that the clamping plate 14 moves downward until the clamping plate 14 rests on the top of the rotor core 4. Then, the rotor core 4 is inserted with magnets. The clamping plate 14 generates a downward thrust on the rotor core 4, thereby preventing the rotor core 4 from being pushed upward when the magnets are inserted.

[0024] Example 3: On the basis of Example 2, in order to conveniently install magnets 12 for each group of magnetic steel slots 22, several groups of magnetic steel seats 9 are fixed to the top of the workbench 1. The magnetic steel seat 9 is a "U"-shaped plate structure. A push rod 11 is slidably connected between the two side plates of the magnetic steel seat 9. A spring 10 is fixed between the push rod 11 and the inner wall of the magnetic steel seat 9. Several groups of magnets 12 are arranged on the other end of the push rod 11.

[0025] The push rod 11 is pushed in the direction away from the base 3. The movement of the push rod 11 causes the spring 10 to be compressed by the inner wall of the magnetic steel seat 9 and the push rod 11. Then several groups of magnetic steels 12 are placed between the push rod 11 and the base 3. After that, the push rod 11 is slowly released. The spring 10 presses the push rod 11 against the surface of the group of magnetic steels 12 farthest from the base 3 under its own elastic action. When one magnet insertion is completed, the distance that the push rod of the second hydraulic push rod mechanism 15 extends out of the hydraulic cylinder becomes shorter, so that the push plate 8 withdraws from the magnetic steel groove 22. After the push plate 8 withdraws, the spring 10 pushes the push rod 11 in the direction close to the base 3, thereby automatically pushing the next group of magnetic steels 12 into the magnetic steel groove 22, and the work of installing the magnetic steel 12 into the magnetic steel groove 22 can be completed conveniently.

[0026] Example 4: On the basis of Example 3, in order to realize the positioning of the rotor core 4, the rotor core 4 has an annular structure, the inner ring of the rotor core 4 is circular, and several groups of grooves are provided on the surface of the outer ring of the rotor core 4. The top of the base 3 is fixed with a positioning rod 6 and a positioning seat 23. The positioning rod 6 has a cylindrical structure and is movably inserted in the inner ring of the rotor core 4. Several groups of positioning seats 23 are provided, and the positioning seats 23 are movably inserted in the grooves of the outer ring of the rotor core 4.

[0027] The positioning rod 6 at the top of the base 3 extends into the inner ring of the rotor core 4 to radially position the rotor core 4, and the positioning seat 23 at the top of the base 3 extends into the groove of the outer ring of the rotor core 4 to circumferentially position the rotor core 4, which can conveniently align the groups of reserved holes 5 on the surface of the rotor core 4 with the groups of magnetic steel slots 22 on the surface of the base 3. At the same time, when inserting the magnets, the clamping plate 14 is pressed against the top of the rotor core 4 to completely position the rotor core 4. After the magnets are inserted, the distance that the tappet of the first hydraulic tappet mechanism 13 extends out of the hydraulic cylinder becomes shorter, so that the clamping plate 14 is away from the top of the rotor core 4, thereby facilitating the removal of the rotor core 4 with the inserted magnets from the top of the base 3.

[0028] Example 5: On the basis of Example 4, in order to prevent the workers' hands from being pressed by the pressing plate 14, a connecting rod 17 is fixed on the surface of the pressing plate 14, and a rack 18 is fixed to the other end of the connecting rod 17. The rack 18 is connected to the side of the top seat 2 by sliding up and down. A gear shaft 20 is rotatably connected to the surface of the top seat 2, and a gear 19 is fixed to one end of the gear shaft 20, which meshes with the rack 18. A shift rod 21 is fixed to the other end of the gear shaft 20, and the shift rod 21 has a rectangular rod structure.

[0029] When the clamping plate 14 moves downward, the clamping plate 14 drives the rack 18 to move downward through the connecting rod 17. The movement of the rack 18 drives the gear 19 to rotate under the meshing action. The gear 19 drives the shift lever 21 to rotate through the gear shaft 20. The rotation of the shift lever 21 shifts the worker's hand that is inserted between the workbench 1 and the top seat 2, and pushes the worker's hand away from the bottom of the clamping plate 14, thereby preventing the worker's hand from being pressed by the clamping plate 14.

[0030] In actual use, the rotor core 4 is placed on the top of the base 3 set at the top of the workbench 1, so that the several groups of reserved holes 5 on the surface of the rotor core 4 are aligned with the several groups of magnetic steel grooves 22 opened on the surface of the base 3, and then the magnetic steel 12 is installed into each group of magnetic steel grooves 22. Finally, the distance that the push rod of the second hydraulic push rod mechanism 15 extends from the hydraulic cylinder becomes longer, so that the push plate 16 moves upward. The movement of the push plate 16 causes the top of each group of push pieces 8 to extend from the top of the push hole 7, thereby pushing each group of magnetic steel 12 upward, so that each group of magnetic steel 12 is pushed into each group of reserved holes 5 at the same time, thereby greatly improving the efficiency of inserting magnetic steel into the rotor core; after the rotor core 4 is placed on the top of the base 3, the surface of the top seat 2 is aligned. The push rod of the fixed first hydraulic push rod mechanism 13 extends a greater distance from the hydraulic cylinder, thereby causing the clamping plate 14 to move downward until the clamping plate 14 rests on the top of the rotor core 4. Then, the rotor core 4 is inserted with magnets. The clamping plate 14 generates a downward thrust on the rotor core 4, thereby preventing the rotor core 4 from being pushed upward when the magnets are inserted. The push rod 11 is pushed away from the base 3. The movement of the push rod 11 causes the spring 10 to be compressed by the inner wall of the magnetic steel seat 9 and the push rod 11. Then, several groups of magnetic steels 12 are placed between the push rod 11 and the base 3. After that, the push rod 11 is slowly released. Under the action of its own elasticity, the spring 10 presses the push rod 11 against the surface of the group of magnetic steels 12 farthest from the base 3. When one push rod is completed, After the magnet is inserted, the distance that the push rod of the second hydraulic push rod mechanism 15 extends out of the hydraulic cylinder becomes shorter, so that the push plate 8 withdraws from the magnetic steel groove 22. After the push plate 8 withdraws, the spring 10 pushes the push rod 11 in the direction close to the base 3, thereby automatically pushing the next group of magnetic steels 12 into the magnetic steel groove 22, and the work of installing the magnetic steel 12 into the magnetic steel groove 22 can be completed conveniently; the positioning rod 6 at the top of the base 3 extends into the inner ring of the rotor core 4 to radially position the rotor core 4, and the positioning seat 23 at the top of the base 3 extends into the groove of the outer ring of the rotor core 4 to circumferentially position the rotor core 4, which can conveniently align the groups of reserved holes 5 on the surface of the rotor core 4 with the groups of magnetic steel grooves 22 on the surface of the base 3. At the same time, when inserting the magnet, press tightly The plate 14 is pressed against the top of the rotor core 4 to completely position the rotor core 4. After the magnets are inserted, the distance that the push rod of the first hydraulic push rod mechanism 13 extends out of the hydraulic cylinder becomes shorter, so that the pressing plate 14 is away from the top of the rotor core 4, thereby facilitating the removal of the rotor core 4 with the inserted magnets from the top of the base 3; when the pressing plate 14 moves downward, the pressing plate 14 drives the rack 18 to move downward through the connecting rod 17, and the movement of the rack 18 drives the gear 19 to rotate under the meshing action, and the gear 19 drives the shift rod 21 to rotate through the gear shaft 20. The rotation of the shift rod 21 shifts the worker's hand extended between the workbench 1 and the top seat 2, and shifts the worker's hand from the bottom of the pressing plate 14, thereby preventing the worker's hand from being pressed by the pressing plate 14.
