Description

Technical Field

[0001] The present invention relates to the technical field of magnetic tile pasting, and particularly to an automatic magnetic tile pasting device and method for an electric motor rotor body. Background Art

[0002] In the field of electric motor manufacturing, the precise pasting of magnetic tiles (permanent magnets) is one of the key processes affecting the performance of electric motors. Magnetic tiles usually need to be firmly and accurately pasted on the surface of the rotor or stator, and their pasting quality directly affects the electromagnetic characteristics, operating efficiency, and reliability of the electric motor. The pasting of electric motor magnetic tiles is mainly restricted by the limitations of traditional manual or semi-automatic pasting methods, with problems such as low efficiency, poor accuracy, and insufficient consistency, making it difficult to meet the production requirements of modern high-efficiency electric motors.

[0003] In electric motor manufacturing, magnetic tiles need to be precisely pasted on the surface of the rotor or stator. Traditional methods rely on manual operation, with problems such as low efficiency, poor consistency, easy occurrence of position deviation or uneven glue layer, affecting the performance of the electric motor. Although early semi-automatic equipment partially replaced manual labor, its positioning accuracy was insufficient, and it could not recycle the partitions that fell during the pasting of magnetic tiles, increasing unnecessary workload and reducing efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an automatic magnetic tile pasting device and method for an electric motor rotor body to solve the problems that traditional pasting relies on manual operation, has low efficiency, poor consistency, and the pasted magnetic tiles are prone to position deviation or uneven glue layer.

[0005] Based on the above purpose, the present invention provides an automatic magnetic tile pasting device for an electric motor rotor body, including a base and a rotor body that can rotate. The rotor body is inserted into the base. A positioning mechanism for limiting and fixing the rotor body is provided on the base. Above the positioning mechanism is a magnetic tile seat, and multiple magnetic tiles are placed in the magnetic tile seat. A magnetic tile pressing mechanism for pressing the magnetic tiles into the inner side of the rotor body is provided on the magnetic tile seat; it also includes a coupling agent coating wheel provided below the magnetic tile seat and a glue coating wheel provided above the positioning mechanism. The glue coating wheel can move up and down, so that before the magnetic tile pressing mechanism presses the magnetic tiles into the rotor body, the glue coating wheel can first coat the inner side of the rotor body with glue. The coupling agent coating wheel can move along the length direction of the magnetic tile seat, so that during the process of the magnetic tile pressing mechanism pressing the magnetic tiles into the rotor body, the coupling agent coating wheel can coat the descending magnetic tiles with coupling agent; inside the positioning mechanism, there is a magnetic tile tensioning mechanism and multiple pressing plate frames. The magnetic tile tensioning mechanism can contact the magnetic tiles entering the rotor body to press the magnetic tiles tightly against the inner side of the rotor body. Multiple pressing plates are placed in the pressing plate frames, and a pressing plate pressing mechanism is provided in the pressing plate frames.

[0006] Preferably, the positioning mechanism includes a positioning ring arranged above the rotor body. A plurality of positioning rods are fixedly arranged at equal intervals on the outer side of the positioning ring. Positioning grooves for inserting the positioning rods are formed on the base. A locking bolt in threaded connection with the outer side of the rotor body is arranged on the positioning rod.

A channel for the magnetic tile to pass through is formed between two adjacent first through grooves.

[0008] Preferably, the magnetic tile seat is arranged above the positioning ring. A partition is placed between two adjacent magnetic tiles in the magnetic tile seat. The number of magnetic tile seats is two. The number of magnetic tiles in each of the two magnetic tile seats is twelve. All the magnetic tiles placed in one magnetic tile seat are N poles, and all the magnetic tiles placed in the other magnetic tile seat are S poles. The thickness of the partition is greater than that of the magnetic tile, and the width of the partition is less than that of the magnetic tile. An electric push rod I is installed at one end of the magnetic tile seat away from the positioning ring. A second through groove adapted to the partition is formed at one end of the magnetic tile seat close to the positioning ring. The width of the second through groove is less than that of the magnetic tile. The output end of the electric push rod I extends into the magnetic tile seat and is fixedly connected with a push plate I for pushing the magnetic tile to move. A notch for the magnetic tile to move downwards is formed on the lower surface of the magnetic tile seat. The notch is vertically aligned with the channel.

[0009] Preferably, the magnetic tile pressing-in mechanism includes an electric push rod II installed on the side surface of the magnetic tile seat. The output end of the electric push rod II is fixedly provided with a lower pressing plate through a connecting plate, and the lower pressing plate is located directly above the notch.

[0010] Preferably, an electric push rod III is installed on the lower surface of the magnetic tile seat, and the output end of the electric push rod III is connected with a coupling agent coating wheel. An electric push rod IV is installed on the side surface of one of the magnetic tile seats, and the output end of the electric push rod IV is connected with a glue coating wheel through a bracket.

[0011] Preferably, the magnetic tile tensioning mechanism includes a connecting column arranged in the positioning ring. An electric push rod V is installed at the bottom end of the connecting column. The output end of the electric push rod V is fixedly connected with two limiting plates. A storage box is fixed on the tops of the two limiting plates. An extrusion plate is fixed on the limiting plate, and the top of the extrusion plate is inclined.

[0012] Preferably, the number of platen frames is four, and the four platen frames are fixedly arranged on the connecting column at equal intervals. A gasket is placed between two adjacent platens in the platen frame. The number of platens 7 in each of the four platen frames 25 is six. The platen pressing mechanism includes a support block fixed in the platen frame. Two guide rods are fixed on the support block. Guide holes adapted to the guide rods are formed in both the platen and the gasket. An electric push rod six is installed on the support block. The electric push rod six is located between the two guide rods, and a push plate two for pushing the platen to move is fixedly connected to the output end of the electric push rod six.

[0013] Preferably, the distance between the end of the platen frame away from the connecting column and the magnetic tile on the inner side of the rotor body is less than the thickness of the platen, and a gasket storage bag is fixed at the end of the platen frame away from the connecting column.

[0014] A pasting method for an automatic magnetic tile pasting device of a motor rotor body includes the following steps: S1. The magnetic tile seat is connected to an external rotating device, and the connecting column is connected to an external lifting device. In the initial state, the magnetic tile seat is rotated to one side, and the platen frame is lifted to a certain height so that the magnetic tile seat and the platen frame do not interfere with the rotor body (2) being inserted into the base (1) for preliminary positioning. Manually insert the positioning rod into the positioning groove so that the pressing block and the positioning plate are respectively in contact with the top and the inner side of the rotor body, and then tighten the locking bolt to realize the limit fixation of the rotor body. S2. Rotate the magnetic tile seat to the original position and lower the platen frame to the original position. The electric push rod pushes the glue application wheel downward to apply glue to the pasting positions of two inner magnetic tiles of the rotor body. Then the base drives the rotor body to rotate clockwise by 30°, and the glue application wheel moves downward again to reapply glue to the inner side of the rotor body. S3. While reapplying glue, the electric push rod two pushes the lower platen to press two magnetic tiles to fall at a time. During the falling process of the magnetic tiles, the electric push rod three pushes the coupling agent application wheel to move to the notch so that the magnetic tiles come into contact with the coupling agent application wheel during the falling process to automatically apply the coupling agent. S4. The lower platen continues to push the magnetic tiles downward into the channel, and the magnetic tiles stay in the channel for 10 to 20 seconds to wait for the coupling agent to volatilize, and then continue to move downward. Subsequently, the electric push rod five pushes the extrusion plate to move, and the extrusion plate presses the magnetic tiles tightly against the rotor body. At the same time, another two magnetic tiles move in the magnetic tile seat under the push of the electric push rod one. The partition between the two magnetic tiles falls into the storage box through the through slot two, and then the electric push rod five retracts. S5. The rotor body continues to rotate by 30°, and another two magnetic tiles are pressed into the rotor body. When a certain number of magnetic tiles are pasted onto the rotor body, the electric push rod six pushes the platen to move, and the four platens can be simultaneously pressed between two adjacent magnetic tiles until all twenty-four magnetic tiles and twenty-four platens are completely installed. After the pressing plate is pressed in, the magnetic tile pressing mechanism, the positioning mechanism, the magnetic tile tensioning mechanism, and the pressing plate pressing mechanism all withdraw from the rotor body and return to the initial state, and the pressing plate is riveted tightly.

[0015] The beneficial effects of the present invention are as follows: First, through the settings of the positioning ring, the pressing plate, the positioning plate, the positioning rod, and the locking bolt, the rotor body can be limited and fixed again, avoiding the offset of the rotor body during the pasting of the magnetic tiles. Moreover, the base is driven by an external power device, so that the base can drive the fixed rotor body to rotate, facilitating the rotor body to rotate 30° after pasting two magnetic tiles, and continuing to paste the remaining parts inside the rotor body.

[0016] Second, through the settings of the glue application wheel, the coupling agent application wheel, and the lower pressing plate, while the glue application wheel moves down again to re-apply glue to the inside of the rotor body, the lower pressing plate moves down to press two magnetic tiles to fall at one time. During the falling process of the magnetic tiles, the electric push rod three pushes the coupling agent application wheel to move, so that the magnetic tiles contact the coupling agent application wheel during the falling process, realizing automatic application of the coupling agent. The lower pressing plate continues to push the magnetic tiles down to enter the channel. The channel plays a role in limiting the magnetic tiles, and the magnetic tiles stay in the channel for 10 seconds - 20 seconds to wait for the coupling agent to volatilize. Subsequently, under the extrusion of the extrusion plate, the magnetic tiles are pressed tightly against the rotor body, realizing staged pressing. Moreover, the two magnetic tile seats store the N pole and the S pole separately, which can avoid the wrong installation of the magnetic poles from the source and improve the pasting efficiency and pasting quality.

[0017] Third, during the process of pasting the magnetic tiles and pressing in the pressing plate, the automatic storage of the partition plates and gaskets is realized, continuous feeding is achieved, manual intervention is reduced, and the installation efficiency is further improved.

[0023] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown in the figure, an automatic magnetic tile pasting device for a motor rotor body includes a base 1 capable of rotating and a rotor body 2. The base 1 is driven by an external power device to achieve free rotation of the base 1. The rotor body 2 is inserted into the base 1. A plurality of riveting holes are equidistantly arranged on the circumferential surface of the rotor body 2. A positioning mechanism for limiting and fixing the rotor body 2 is arranged on the base 1. Above the positioning mechanism, there are two magnetic tile seats 3. The magnetic tile seats 3 are connected to an external rotating device to facilitate driving the magnetic tile seats 3 to rotate and shift, avoiding interference with the insertion of the rotor body 2 into the base 1. A plurality of magnetic tiles 4 are placed in the magnetic tile seats 3. A magnetic tile pressing mechanism for pressing the magnetic tiles 4 into the inner side of the rotor body 2 is arranged on the magnetic tile seats 3; it also includes a coupling agent coating wheel 5 arranged below the magnetic tile seats 3 and a glue coating wheel 6 arranged above the positioning mechanism. The glue coating wheel 6 can move up and down. The lower surface of the magnetic tile seat 3 is equipped with an electric push rod three, and the output end of the electric push rod three is connected to the coupling agent coating wheel 5. One side of one of the magnetic tile seats 3 is equipped with an electric push rod four, and the output end of the electric push rod four is connected to the glue coating wheel 6 through a bracket, so that before the magnetic tile pressing mechanism presses the magnetic tiles 4 into the rotor body 2, the glue coating wheel 6 can first coat the inner side of the rotor body 2 with glue. The coupling agent coating wheel 5 can move along the length direction of the magnetic tile seat 3, so that during the process of the magnetic tile pressing mechanism pressing the magnetic tiles 4 into the rotor body 2, the coupling agent coating wheel 5 can contact the magnetic tiles 4, thereby coating the coupling agent on the descending magnetic tiles 4; a magnetic tile tensioning mechanism and a plurality of pressing plate frames 25 are arranged inside the positioning mechanism. The magnetic tile tensioning mechanism is connected to the pressing plate frames 25, and both are connected to an external lifting device, so that when the rotor body 2 is inserted into the base 1, the external lifting device can drive the magnetic tile tensioning mechanism to rise, thus not interfering with the insertion of the rotor body 2. The magnetic tile tensioning mechanism can contact the magnetic tiles 4 entering the rotor body 2 to press the magnetic tiles 4 tightly on the inner side of the rotor body 2. A plurality of pressing plates 7 are placed in the pressing plate frames 25, and a pressing plate pressing mechanism is arranged in the pressing plate frames 25.

[0024] In the initial state, the external rotating device drives the magnetic tile seats 3, the magnetic tile pressing mechanism, the coupling agent coating wheel 5 and the glue coating wheel 6 to rotate and shift. At the same time, the external lifting device drives the magnetic tile tensioning mechanism to rise, so as not to interfere with the insertion of the rotor body 2 and the positioning mechanism. Manually operate the positioning mechanism to drop, and cooperate with the base 1 to reposition the rotor body 2. Subsequently, the electric push rod four pushes the glue coating wheel 6 down to coat the inner side of the rotor body 2 with glue. The electric push rod three pushes the coupling agent coating wheel 5 to move, so that when the magnetic tile pressing mechanism pushes the magnetic tiles 4 down, the magnetic tiles 4 can contact the coupling agent coating wheel 5 to achieve automatic coating of the coupling agent. The magnetic tile pressing mechanism continues to push the magnetic tiles 4 down. Subsequently, under the extrusion of the magnetic tile tensioning mechanism, the magnetic tiles 4 are tightly attached to the rotor body 2. When a certain number of magnetic tiles 4 are pasted on the rotor body 2, the pressing plate pressing mechanism presses the pressing plates 7 between adjacent two magnetic tiles 4 until all twenty-four magnetic tiles 4 and twenty-four pressing plates 7 are installed.

[0025] In a preferred embodiment of the present invention, the positioning mechanism includes a positioning ring 8 disposed above the rotor body 2. A plurality of positioning rods 9 are fixedly arranged at equal intervals on the outer side of the positioning ring 8. Positioning grooves for inserting the positioning rods 9 are formed on the base 1. A locking bolt 10 in contact with the outer side of the rotor body 2 is threadedly connected to the positioning rod 9. A plurality of pressing blocks 11 are fixedly connected at equal intervals on the lower surface of the positioning ring 8. The number of pressing blocks is 24. The pressing blocks 11 are in contact with the top of the rotor body 2. A plurality of positioning plates 12 are fixedly connected at equal intervals on the inner side of the positioning ring 8. The number of positioning plates 12 is 24. The positioning plates 12 are in contact with the inner side of the rotor body 2. A first through groove is formed on the side surface of the positioning plate 12, and a channel for the magnetic tile 4 to pass through is formed by two adjacent first through grooves. Since the number of positioning plates 12 is 24, it can be known that the number of channels is also 24, that is, the number of magnetic tiles 4 pasted in the rotor body 2 is 24. The angle between two adjacent magnetic tiles 4 is 15°. Since the number of magnetic tile seats 3 is two, two magnetic tiles 4 are pressed in each time. That is, after pasting two magnetic tiles 4 each time, the base 1 drives the rotor body 2 to rotate by an angle of 30°.

[0026] When the rotor body 2 needs to be positioned, manually insert the positioning rod 9 into the positioning groove, so that the pressing block 11 is in contact with the top of the rotor body 2, and at the same time the positioning plate 12 is in contact with the inner side of the rotor body 2, and tighten the locking bolt 10 so that the end of the locking bolt 10 is in contact with the outer side of the rotor body 2. With the cooperation of the three positioning rods 9 and the locking bolt 10, the limit fixation of the rotor body 2 is realized, so that when the base 1 rotates, it can drive the rotor body 2 to rotate together, which is convenient for the rotor body 2 to rotate 30° after pasting two magnetic tiles 4, and continue to paste the remaining parts on the inner side of the rotor body 2.

[0027] In another preferred embodiment of the present invention, the magnetic tile seat 3 is disposed above the positioning ring 8. A partition 13 is placed between two adjacent magnetic tiles 4 in the magnetic tile seat 3. The number of magnetic tile seats 3 is two. The number of magnetic tiles 4 in each of the two magnetic tile seats 3 is twelve. The magnetic tiles 4 placed in one magnetic tile seat 3 are all N poles, and the magnetic tiles 4 placed in the other magnetic tile seat 3 are all S poles; The thickness of the partition plate 13 is greater than that of the magnetic tile 4, and the width of the partition plate 13 is less than that of the magnetic tile 4. An electric push rod 14 is installed at one end of the magnetic tile seat 3 away from the positioning ring 8. A second through groove adapted to the partition plate 13 is provided at one end of the magnetic tile seat 3 close to the positioning ring 8. The width of the second through groove is less than that of the magnetic tile 4. The output end of the electric push rod 14 extends into the magnetic tile seat 3 and is fixedly connected with a first push plate for pushing the magnetic tile 4 to move. A notch 15 for the magnetic tile 4 to move downward is provided on the lower surface of the magnetic tile seat 3, and the notch 15 is vertically aligned with the channel; the magnetic tile pressing mechanism includes an electric push rod 16 installed on the side of the magnetic tile seat 3. The output end of the electric push rod 16 is fixed with a lower pressing plate 17 through a connecting plate, and the lower pressing plate 17 is located directly above the notch 15.

[0028] After the glue application wheel applies glue to the inner side of the rotor body, the electric push rod 16 pushes the lower pressing plate 17 to press two magnetic tiles 4 to fall at a time. During the falling process of the magnetic tiles 4, the electric push rod 3 pushes the coupling agent application wheel 5 to move, so that the magnetic tiles 4 come into contact with the coupling agent application wheel 5 during the falling process to realize automatic application of the coupling agent. The lower pressing plate 17 continues to push the magnetic tiles 4 to move downward into the channel. The channel plays a limiting role on the magnetic tiles, and waits for 10 to 20 seconds in the channel for the coupling agent to volatilize. Subsequently, under the extrusion of the magnetic tile tensioning mechanism, the magnetic tiles 4 are tightly attached to the rotor body 2, and the two magnetic tile seats 3 store the N pole and the S pole separately, which can avoid the wrong installation of the magnetic poles from the source and improve the pasting efficiency and pasting quality.

[0029] In another preferred embodiment of the present invention, the magnetic tile tensioning mechanism includes a connecting column 18 arranged in the positioning ring 8. An electric push rod 19 is installed at the bottom end of the connecting column 18. The output end of the electric push rod 19 is fixedly connected with two limiting plates 20. A storage box 21 is fixed on the tops of the two limiting plates 20. An extrusion plate 22 is fixed on the limiting plate 20, and the top of the extrusion plate 22 is inclined.

[0030] The electric push rod 19 pushes the extrusion plate 22 to move. The limiting plate 20 plays a limiting role on the magnetic tile 4 to prevent the magnetic tile 4 from shifting and rotating. The extrusion plate 22 tightly attaches the magnetic tile 4 to the rotor body 2. At the same time, two more magnetic tiles 4 move in the magnetic tile seat 3 under the push of the electric push rod 14. Since the width of the magnetic tile 4 is adapted to the second through groove, and the width of the partition plate 13 is greater than the width of the through groove, and the thickness of the partition plate 13 is greater than that of the magnetic tile 4, the partition plate 13 will not fall out of the notch 15 during the moving process, and the magnetic tile 4 will not fall out of the second through groove, so that the partition plate 13 between the two magnetic tiles 4 can fall into the storage box 21 through the second through groove. Then the electric push rod 19 contracts, the rotor body 2 continues to rotate, and the magnetic tile 4 is pasted continuously.

[0031] It should be noted that the number of the pressing plate frames 25 is four, and the four pressing plate frames 25 are fixed on the connecting column 18 at equal intervals. Gaskets are placed between two adjacent pressing plates 7 in the pressing plate frames 25, and the number of the pressing plates 7 in each of the four pressing plate frames 25 is six; the pressing plate pressing mechanism includes a support block fixed in the pressing plate frame 25. Two guide rods 23 are fixed on the support block. Guide holes adapted to the guide rods 23 are formed in both the pressing plate 7 and the gasket. An electric push rod six 24 is installed on the support block. The electric push rod six 24 is located between the two guide rods 23, and a push plate two for pushing the pressing plate 7 to move is fixedly connected to the output end of the electric push rod six 24.

[0032] The distance between the end of the pressing plate frame 25 away from the connecting column 18 and the magnetic tile 4 pasted on the inner side of the rotor body 2 is less than the thickness of the pressing plate 7, and the distance between the end of the pressing plate frame 25 away from the connecting column 18 and the magnetic tile 4 pasted on the inner side of the rotor body 2 is greater than the thickness of the gasket. A gasket storage bag 26 is fixed at the end of the pressing plate frame 25 away from the connecting column 18.

[0033] After a certain number of magnetic tiles 4 are pasted on the rotor body 2, the electric push rod six 24 pushes the pressing plate 7 to move. The pressing plate 7 moves along the guide rod 23 in the pressing plate frame 25. Since the distance between the end of the pressing plate frame 25 and the magnetic tile 4 pasted in the rotor body 2 is less than the thickness of the magnetic tile 4, the magnetic tile 4 will not fall off when moving, and the four pressing plates 7 can be simultaneously pressed between two adjacent magnetic tiles 4. And since the distance between the end of the pressing plate frame 25 and the magnetic tile 4 in the rotor body 2 is greater than the thickness of the gasket, the gasket can fall into the gasket storage bag 26. During the process of pasting the magnetic tile 4 and pressing the pressing plate 7, the automatic storage of the partition plate 13 and the gasket is realized, continuous feeding is achieved, manual intervention is reduced, and the installation efficiency is further improved.

[0034] A pasting method of an automatic magnetic tile pasting device for a motor rotor body includes the following steps: S1. The magnetic tile seat 3 is connected to an external rotating device, and the connecting column 18 is connected to an external lifting device. In the initial state, the magnetic tile seat 3 is rotated to one side, and the pressing plate frame 25 is lifted to a certain height so that the magnetic tile seat 3 and the pressing plate frame 25 do not prevent the rotor body 2 from being inserted into the base 1 for preliminary positioning. Manually insert the positioning rod 9 into the positioning groove so that the pressing block 11 and the positioning plate 12 are respectively in contact with the top and the inner side of the rotor body 2, and then tighten the locking bolt 10 to realize the limit fixation of the rotor body 2. S2. Rotate the magnetic tile seat 3 to the original position, and lower the pressing plate frame 25 to the original position. The electric push rod four pushes the glue application wheel 6 to move downwards to apply glue to the pasting positions of two magnetic tiles on the inner side of the rotor body 2. Then the base 1 drives the rotor body 2 to rotate clockwise by 30°, and the glue application wheel 6 moves downwards again to apply glue to the inner side of the rotor body 2 again. S3. While applying glue again, the electric push rod II 16 pushes the lower pressing plate 17 to press two magnetic tiles 4 down at a time. During the falling process of the magnetic tiles 4, the electric push rod III pushes the coupling agent coating wheel 5 to move, so that the magnetic tiles 4 contact the coupling agent coating wheel 5 during the falling process, realizing automatic coupling agent coating; S4. The lower pressing plate 17 continues to push the magnetic tiles 4 downward into the channel, stays in the channel for 10 to 20 seconds to wait for the coupling agent to volatilize, and then continues to move downward. Subsequently, the electric push rod V 19 pushes the pressing plate 22 to move, and the pressing plate 22 presses the magnetic tiles 4 tightly against the rotor body 2. At the same time, another two magnetic tiles 4 move in the magnetic tile seat 3 under the push of the electric push rod I 14. The partition plate 13 between the two magnetic tiles 4 falls into the storage box 21 through the second through groove, and then the electric push rod V 19 contracts; S5. The rotor body 2 continues to rotate 30°. Another two magnetic tiles 4 are pressed into the rotor body 2. When a certain number of magnetic tiles 4 are pasted onto the rotor body 2, the electric push rod VI 24 pushes the pressing plate 7 to move, and can press the four pressing plates 7 into the space between two adjacent magnetic tiles 4 at the same time until all twenty-four magnetic tiles 4 and twenty-four pressing plates 7 are completely installed; S6. After the pressing plate 7 is pressed in, the magnetic tile pressing mechanism, the positioning mechanism, the magnetic tile tensioning mechanism and the pressing plate pressing mechanism all withdraw from the rotor body 2 and return to the initial state. Subsequently, the pressing plate 7 is riveted tightly.

The magnetic tile seat (3) is connected to an external rotating device, and the connecting column (18) is connected to an external lifting device. In the initial state, the magnetic tile seat (3) is rotated to one side, and the pressing plate frame (25) is lifted to a certain height so that the magnetic tile seat (3) and the pressing plate frame (25) do not interfere with the insertion of the rotor body (2) into the base (1) for preliminary positioning. Manually insert the positioning rod (9) into the positioning groove so that the pressing block (11) and the positioning plate (12) are respectively in contact with the top and the inner side of the rotor body (2). Then tighten the locking bolt (10) to realize the limit fixation of the rotor body (2). S2.
