[0018] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are 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 used to limit 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.

[0019] For example, see Figure 1 - Fig.11 The present invention provides a technical solution for a needle disk assembly for inserting magnetic steel into a rotor core: a rotor inserting magnetic steel machine body 1, a sliding base 2 is arranged on the rotor inserting magnetic steel machine body 1, the outer wall at the top of the sliding base 2 is fixedly connected with a fixing seat 3, the outer wall at the top of the fixing seat 3 is provided with a placement groove 31, the inner part of the fixing seat 3 is movably plugged with a needle disk body 51, a fixing rod 5 is fixedly connected through the middle of the top of the needle disk body 51, an insert block 53 is fixedly connected to the outer wall at the bottom of the needle disk body 51, iron sheets 54 are fixedly connected to the outer walls at the bottom of a plurality of insert blocks 53, a guide needle 55 is fixedly connected to the outer wall on one side of the insert block 53, an insert rod 52 is fixedly connected to the outer wall at the top of the needle disk body 51, slots are provided on the outer walls on both sides of the insert block 53, and blocking blocks 79 are fixedly connected to the outer walls on both sides of the needle disk body 51, a rotor core body 4 is movably plugged with the outer wall of the fixing rod 5, a plurality of circular holes 41 are provided on the outer wall at the top of the rotor core body 4, and the inner part of the circular hole 41 is movably plugged with the outer wall of the insert rod 52.

[0020] The arrangement of the insertion rod 52 can prevent the rotor core body 4 from accidentally rotating on the fixing rod 5 after the rotor core body 4 is inserted into the fixing rod 5, and accordingly prevent the rotor core body 4 from rotating due to external force, thereby increasing the stability of the rotor core body 4 on the fixing rod 5.

[0021] Embodiment 2, on the basis of embodiment 1, a limiting groove 33 is fixedly connected to the lower part of the placement groove 31, a magnetic block 34 is fixedly connected to the inner part of the limiting groove 33 at the lower part of the placement groove 31, a positioning groove 32 is provided on the outer wall of the top of the fixing seat 3 at the middle position on one side of the limiting groove 33, the inner parts of the plurality of limiting grooves 33 are movably connected to the outer wall of the plug block 53, the outer wall of the top of the magnetic block 34 is magnetically connected to the outer wall of the bottom of the iron sheet 54, and the inner part of the positioning groove 32 is slidably connected to the outer wall of the guide pin 55.

[0022] By pre-aligning the positioning groove 32 with the guide pin 55, it is avoided that when the needle dial body 51 drives the insertion block 53 to be inserted into the interior of the placement groove 31, the needle dial body 51 needs to be adjusted multiple times to align the insertion block 53 with the limiting groove 33. Accordingly, it is ensured that the needle dial body 51 can be smoothly inserted into the placement groove 31, saving the operation time of the needle dial body 51. The insertion block 53 can be accurately inserted into the limiting groove 33 under the guidance of the guide pin 55, ensuring that the connection between the needle dial body 51 and the fixing seat 3 is both firm and accurate.

[0023] Embodiment 3, on the basis of embodiment 2, a fixing groove 66 is provided in the middle position inside the placement groove 31, a telescopic tube 68 is fixedly connected to the lower part inside the fixing groove 66, a reset spring 69 is fixedly connected to the inside of the telescopic tube 68, a sealing gasket 2 67 is connected to the outer wall of the top of the telescopic tube 68, the outer wall of the sealing gasket 2 67 is in movably contact with the inside of the fixing groove 66, a through hole is provided in the outer wall of the top of the sealing gasket 2 67, a sealing gasket 1 64 is fixedly connected to the outer wall of the bottom of the fixing rod 5, a circular groove is provided in the middle position of the bottom of the fixing rod 5, an insertion tube 65 is fixedly connected to the inside of the circular groove, the outer wall of the insertion tube 65 is movably plugged into the inside of the through hole, and the outer wall of the bottom of the sealing gasket 1 64 is in movably contact with the outer wall of the top of the sealing gasket 2 67.

[0024] The close contact between the sealing gasket 2 67 and the sealing gasket 1 64 effectively prevents the leakage of gas or liquid, thereby improving the sealing between the fixed rod 5 and the telescopic tube 68. When the gas inside the telescopic tube 68 is reduced, due to the effect of the air pressure difference, a certain suction force will be generated between the telescopic tube 68 and the fixed rod 5. This suction force helps to fix the fixed rod 5 more firmly inside the fixing groove 66, thereby enhancing the stability of the needle disk body 51 inside the placement groove 31, and helping to reduce loosening or displacement caused by vibration or external force.

[0025] Embodiment 4, on the basis of embodiment 3, a T-shaped block 72 is fixedly connected to the lower part of the placement groove 31, a cavity 71 is opened at the lower part of the placement groove 31 near the outer side of the T-shaped block 72, the outer wall of the T-shaped block 72 is slidably connected to the shell 7, the outer wall of the bottom of the shell 7 is movably plugged into the interior of the cavity 71, the top of the shell 7 is movably connected to a top cover 76, the outer wall of the bottom of the top cover 76 is fixedly connected to a soft shell 74, the outer wall of the bottom of the soft shell 74 is fixedly connected to a gravity block 75, the outer wall of the bottom of the gravity block 75 is movably in contact with the outer wall of the top of the T-shaped block 72, the outer walls on both sides of the soft shell 74 are fixedly connected to outlet pipes 78, the outer wall of the outlet pipe 78 is movably connected to the interior of the shell 7, a feeding port is opened on the outer wall of the top of the top cover 76, a piston rod 77 is movably plugged into the feeding hole, the outer wall of the top of the T-shaped block 72 is fixedly connected to a push spring 73, the outer wall of the top of the push spring 73 is fixedly connected to the upper part of the shell 7, and the outer wall of one side of the outlet pipe 78 is movably in contact with the outer wall of one side of the blocking block 79.

[0026] The soft shell 74 inside the outer shell 7 is squeezed. When the soft shell 74 is squeezed, the glue inside the soft shell 74 can be squeezed out from the outlet pipe 78 and sprayed to the inside of the magnetic steel slot on the rotor core body 4. By spraying the glue on the contact surface between the magnetic steel slot and the magnetic steel, the adhesion between the magnetic steel and the magnetic steel slot can be increased, thereby improving the stability of the magnetic steel in the magnetic steel slot and preventing the magnetic steel from loosening or falling off during operation.

[0027] Embodiment 5, on the basis of embodiment 4, the outer wall of the outer shell 7 is located below the outlet pipe 78 and is fixedly connected to a lower locking plate 83, the outer wall of the outer shell 7 is located above the outlet pipe 78 and is fixedly connected to a fixing plate 8, the internal thread of the fixing plate 8 is connected to a threaded rod 81, the outer wall at the bottom of the threaded rod 81 is rotatably connected to a mounting seat 84, the outer wall at the bottom of the mounting seat 84 is fixedly connected to an upper locking plate 82, and the outer wall at the bottom of the upper locking plate 82 is in active contact with the outer wall at the top of the lower locking plate 83.

[0028] By the operator rotating the threaded rod 81 and then through the downward movement of the threaded rod 81, the upper locking plate 82 can be pushed to contact the lower locking plate 83, thereby locking the outlet pipe 78, preventing the outlet pipe 78 from losing its supporting force and moving when the glue inside the soft shell 74 is reduced, and correspondingly preventing the outlet pipe 78 from moving due to losing its supporting force when the glue inside the soft shell 74 is reduced.

[0029] Embodiment 6, on the basis of embodiment 3, a groove is provided on the outer wall of the fixing rod 5, an air bag 62 is fixedly connected inside the groove, an air hole 63 is provided on the inner wall of the air bag 62, an air passage 6 is provided inside the fixing rod 5, the outer wall of the air hole 63 penetrates the inner wall of the fixing rod 5 and is connected to the air passage 6, the outer wall of the air bag 62 is in active contact with the inside of the rotor core body 4, and a sealing rod 61 is threadedly connected inside the fixing rod 5.

[0030] When the gas enters the interior of the airbag 62 through the air hole 63, the airbag 62 will gradually expand and grow as the gas flows in. The airbag 62 becomes bulging, thereby increasing the contact area between the fixing rod 5 and the rotor core body 4, filling the gap between the fixing rod 5 and the rotor core body 4, and further increasing the fixation between the fixing rod 5 and the rotor core body 4, thereby enhancing the stability of the fixation and preventing the loosening of the rotor core body 4 due to vibration or external force. At the same time, as the airbag 62 expands, it acts like a layer of buffer pad, which can absorb and disperse the vibration energy generated by the rotor core body 4 when the magnet is inserted, thereby reducing the noise between the rotor core body 4 and the fixing rod 5.

[0031] In actual use, first, the rotor core body 4 is inserted into the fixing rod 5, and then the rotor core body 4 is pushed downward on the fixing rod 5. The operator rotates and adjusts the rotor core body 4 to align the circular hole 41 on the rotor core body 4 with the insertion rod 52, and then the rotor core body 4 is pushed to contact the needle disk body 51, so that the rotor core body 4 can be fixed on the needle disk body 51. The setting of the insertion rod 52 avoids accidental rotation of the rotor core body 4 on the fixing rod 5 after the rotor core body 4 is inserted into the fixing rod 5, and accordingly prevents the rotation of the rotor core body 4 due to external force, thereby increasing the stability of the rotor core body 4 on the fixing rod 5.

[0032] After the rotor core body 4 is fixed on the needle plate body 51, the operator can insert the needle plate body 51 into the interior of the fixing seat 3. When the needle plate body 51 is inserted into the interior of the placement groove 31, the guide pin 55 is first aligned with the positioning groove 32, and the guide pin 55 is inserted into the interior of the positioning groove 32. Then, the needle plate body 51 drives the rotor core body 4 to push forward, so that the insert block 53 drives the iron sheet 54 to be accurately inserted into the interior of the limiting groove 33. Pre-alignment avoids the need to adjust the needle dial body 51 multiple times to align the insert block 53 with the limiting groove 33 when the needle dial body 51 drives the insert block 53 to be inserted into the interior of the placement groove 31. Accordingly, it is ensured that the needle dial body 51 can be smoothly inserted into the placement groove 31, saving the operation time of the needle dial body 51. The insert block 53 can be accurately inserted into the limiting groove 33 under the guidance of the guide needle 55, ensuring that the connection between the needle dial body 51 and the fixing seat 3 is both firm and accurate.

[0033] Through the magnetic attraction between the magnetic block 34 and the iron sheet 54, when the insert block 53 enters the interior of the limit groove 33, the magnetic attraction between the magnetic block 34 and the iron sheet 54 can effectively fix the insert block 53 in the limit groove 33, preventing the insert block 53 from moving inside the limit groove 33. Since the insert block 53 is firmly fixed in the limit groove 33, during the subsequent insertion of the magnetic steel, the position of the needle disk body 51 is ensured not to be shifted due to external force, which helps to improve the accuracy and reliability of the magnetic steel insertion process.

[0034] When the needle disk body 51 is inserted into the placement groove 31, the fixing rod 5 can be inserted into the fixing groove 66. At this time, the insertion tube 65 on the fixing rod 5 is inserted into the through hole of the sealing gasket 2 67, and the sealing gasket 1 64 contacts the sealing gasket 2 67. When the needle disk body 51 is pushed downward into the placement groove 31, the fixing rod 5 can squeeze the sealing gasket 2 67 downward. Through the downward movement of the sealing gasket 2 67, the telescopic tube 68 can be squeezed. When the telescopic tube 68 is squeezed, the gas inside the telescopic tube 68 is compressed. After the gas inside the telescopic tube 68 is squeezed, it will enter the airway 6 through the insertion tube 65, and then pass through the air holes set in the airway 6. 63. When the gas inside the airway 6 increases, the gas enters into the airbag 62 through the air hole 63. As the gas flows in, the airbag 62 will gradually expand and become larger. As the airbag 62 becomes bulging, the contact area between the fixing rod 5 and the rotor core body 4 is increased, the gap between the fixing rod 5 and the rotor core body 4 is filled, and the fixation between the fixing rod 5 and the rotor core body 4 is further increased, thereby enhancing the stability of the fixation and preventing the loosening of the rotor core body 4 due to vibration or external force. At the same time, as the airbag 62 expands, it acts like a layer of buffer pad, which can absorb and disperse the vibration energy generated by the rotor core body 4 when the magnet is inserted, thereby reducing the noise between the rotor core body 4 and the fixing rod 5.

[0035] The close contact between the sealing gasket 2 67 and the sealing gasket 1 64 effectively prevents the leakage of gas or liquid, thereby improving the sealing between the fixed rod 5 and the telescopic tube 68. When the gas inside the telescopic tube 68 is reduced, due to the effect of the air pressure difference, a certain suction force will be generated between the telescopic tube 68 and the fixed rod 5. This suction force helps to fix the fixed rod 5 more firmly inside the fixing groove 66, thereby enhancing the stability of the needle disk body 51 inside the placement groove 31, and helping to reduce loosening or displacement caused by vibration or external force.

[0036] When it is necessary to remove the fixing rod 5 and the needle disk body 51 from the inside of the placement groove 31, the operator can release the blockage between the sealing rod 61 and the airway 6, so that the external gas can enter the inside of the airway 6, thereby releasing the suction between the fixing rod 5 and the telescopic tube 68. After the fixing rod 5 is moved out from the inside of the fixing groove 66, the telescopic tube 68 can be pushed to quickly restore its original state under the setting of the reset spring 69. The volume inside the telescopic tube 68 will increase, thereby forming a low-pressure area. This low-pressure area will attract external air to enter the interior of the telescopic tube 68 through the through hole. As the gas inside the telescopic tube 68 increases, its internal air pressure will gradually increase until it reaches equilibrium with the external air pressure. At this time, the telescopic tube 68 will remain in the restored shape and be ready for the next insertion of the fixing rod 5.

[0037] It should be noted that: a sealing gasket 3 is provided on the contact surface between the sealing rod 61 and the fixing rod 5 to enhance the sealing between the sealing rod 61 and the fixing rod 5 .

[0038] After the needle disk body 51 drives the rotor core body 4 to be fixed on the fixing seat 3, when the magnet is inserted into the magnet groove on the rotor core body 4, the magnet can push the outer shell 7 downward, and when the outer shell 7 moves downward into the cavity 71, the soft shell 74 inside the outer shell 7 is squeezed. At this time, when the soft shell 74 is squeezed, the glue inside the soft shell 74 can be squeezed out from the outlet pipe 78 and sprayed into the inside of the magnet groove on the rotor core body 4. By spraying the glue on the contact surface between the magnet groove and the magnet, the bonding force between the magnet and the magnet groove can be increased, thereby improving the stability of the magnet in the magnet groove and preventing the magnet from loosening or falling off during operation.

[0039] When the magnet enters the bottom of the magnetic steel slot, it can push the outlet pipe 78 to contact the blocking block 79, further increasing the blocking of the outlet pipe 78, avoiding the glue from continuing to spray out when the outlet pipe 78 moves out of the magnetic steel slot, and correspondingly increasing the blocking effect of the outlet pipe 78.

[0040] It should be noted that a one-way valve is provided inside the outlet pipe 78. The one-way valve is a prior art. When the soft shell 74 is squeezed, the valve opens and the glue flows out. When the squeezing stops, the valve closes to prevent the glue from continuing to flow out. This design is more common in glue extrusion tools or containers and can effectively control the outflow of glue.

[0041] After the magnet is fixed in the magnet slot, the needle disc body 51 drives the rotor core body 4 to be taken out from the placement slot 31, and then the outer shell 7 can be pushed back to its original position and in a standby state under the action of the push spring 73, ready for the next operation.

[0042] When it is necessary to add glue to the inside of the soft shell 74, the piston rod 77 on the top cover 76 can be opened to add glue to the inside of the soft shell 74. The gravity block 75 set at the bottom of the soft shell 74 can prevent the soft shell 74 from shrinking when the glue inside the soft shell 74 becomes less, so that the bottom of the soft shell 74 does not contact the T-block 72. Accordingly, the shape and position of the soft shell 74 can be automatically adjusted by the gravity block 75 to maintain the contact between the soft shell 74 and the T-block 72. Therefore, the operator does not need to frequently check or adjust the state of the soft shell 74, thereby improving the convenience and efficiency of operation.

[0043] When the outlet pipe 78 is inserted into the interior of the outer shell 7, the operator can rotate the threaded rod 81, and then the threaded rod 81 moves downward, so that the upper locking plate 82 and the lower locking plate 83 can be pushed to contact each other, thereby locking the outlet pipe 78, preventing the outlet pipe 78 from losing its supporting force and moving when the glue inside the soft shell 74 is reduced, and correspondingly preventing the outlet pipe 78 from moving due to losing its supporting force when the glue inside the soft shell 74 is reduced.

[0044] When the soft shell 74 needs to be replaced, first release the fixing of the mounting base 84 on the outlet pipe 78, then push the outlet pipe 78 into the interior of the outer shell 7, and then through the movable connection between the top cover 76 and the outer shell 7, the top cover 76 can be removed from the outer shell 7 and the soft shell 74 can be moved out from the interior of the outer shell 7, thereby facilitating the replacement of the soft shell 74.

[0045] It should be noted that the top cover 76 is connected to the outer shell 7 by screws. After the screws are removed, the top cover 76 can be removed from the outer shell 7.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
