Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a press for machining rotor cores. Background Technology

[0002] The rotor core is one of the core components in rotating machinery such as motors and generators. Its main function is to support the rotor coils and improve the magnetic field strength and efficiency. It is usually composed of a rotor core, an upper end plate, a lower end plate, and a motor shaft inserted into the center of the rotor core. During the processing, the rotor core is shaped by a press.

[0003] Patent publication number CN220444876U discloses a press for machining rotor cores, including a fixed support assembly, a core guide assembly, a core drive assembly, a core positioning assembly, and a core shaping assembly. The fixed support assembly is located at the bottom of the entire press. The core guide assembly is mounted on the top surface of the fixed support assembly and has a sliding mechanism. The core drive assembly is located on one side of the core guide assembly. The bottom of the core positioning assembly is mounted on the core guide assembly via the sliding mechanism. The bottom of the core shaping assembly is mounted on the top surface of the fixed support assembly. This patent includes a core positioning assembly comprising a fixed base and a positioning part. The positioning part is mounted on the fixed base and includes a positioning shaft and a placement column. The positioning shaft and placement column are coaxially arranged. The positioning shaft positions the rotor core, and the bottom surface of the rotor core contacts the top surface of the placement column, thereby providing positioning support for the rotor core and improving its stability.

[0004] However, the device still has shortcomings: the device relies on the positioning shaft to position and press the rotor core, but since the bottom part of the rotor core is located at the positioning shaft, after the rotor core is pressed and loses the resistance of the top pressing mechanism, the upright rotor core is prone to tipping over. At this time, the staff needs to hold it by hand or use external equipment for support, which increases the probability of the rotor core being damaged by bumps and increases the workload of the staff. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a press for machining rotor cores, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a press for processing rotor cores, comprising a pressing mechanism, a base fixedly installed at the bottom of the inner wall of the pressing mechanism, a storage cylinder fixed at the center of the top of the base, an electric slide rail provided on the back of the inner wall of the pressing mechanism, a T-shaped plate slidably installed inside the electric slide rail, two telescopic rods symmetrically and fixedly installed at the bottom of the T-shaped plate, a center plate penetrating and fixedly installed through the outer wall of the telescopic rods, a pressure block penetrating and fixedly installed inside the center plate, a circular groove plate fixedly installed at the bottom of the telescopic end of the telescopic rods, two support rods symmetrically and fixedly installed at the bottom of the circular groove plate, a U-shaped telescopic frame hinged to the outer wall of the center plate by a torsion spring, a fastening device provided around the U-shaped telescopic frame to prevent displacement of the rotor core after connection, an anti-deformation device for supporting the bottom of the pressing components provided below the fastening device, and a clamping arc plate hinged to the bottom of the telescopic end of the U-shaped telescopic frame.

[0007] According to the above technical solution, the back of the pressing mechanism is provided with a ventilation groove, the bottom edge of the inner wall of the pressing mechanism is provided with a sliding groove, the front of the pressing mechanism is provided with a safety door, the bottom end of the rotor core bottom accessory is located inside the storage cylinder during the pressing process, and the top surface of the accessory is in contact with the top of the storage cylinder, the inside of the storage cylinder is provided with a vertical groove, the bottom of the pressing block is in contact with the top of the rotor core during the pressing process, the bottom of the rotor core is in contact with the top of the circular groove plate, and the bottom connecting shaft of the rotor core is located below the circular groove plate.

[0008] According to the above technical solution, the bottom end of the pressure block is located below the center plate, a slide rail is provided inside the circular groove plate, a spring is provided between the top of the base and the bottom of the circular groove plate, the bottom end of the support rod movably passes through the base and the inside of the pressing mechanism, the U-shaped telescopic frame is elastically designed, the bottom of the clamping arc plate is slidably installed on the top of the circular groove plate, the clamping arc plate limits the outer wall of the rotor core during the pressing process, the part to be pressed is placed inside the storage cylinder, at this time the top of the part is located at the top of the storage cylinder, then the bottom connecting shaft of the rotor core is inserted vertically into the center of the circular groove plate, and the bottom of the rotor core contacts the top of the circular groove plate, the electric slide rail is activated, the electric slide rail drives the T-shaped plate to move downward, the T-shaped plate drives the telescopic rod to move synchronously, that is, the telescopic rod retracts downward, and during the process of the telescopic rod driving the center plate to move downward, the center plate drives the pressure block to move synchronously, at this time the bottom of the pressure block contacts the top of the rotor core, when the telescopic rod is retracted, the telescopic rod causes the circular groove plate to generate a downward force due to the downward pressure of the T-shaped plate. At this point, the circular slot plate drives the support rod to penetrate deeper into the pressing mechanism. The support rod limits the circular slot plate's vertical downward movement, and the base's limiting action causes the circular slot plate to compress the spring, causing it to move closer to the component. Under the pressure of the pressing block and the support of the storage cylinder, the bottom connecting shaft of the rotor core is inserted into the component to complete the pressing process. When the T-shaped plate resets via the electric slide rail, the downward pressure on the circular slot plate is released. The circular slot plate is then pushed upward by the spring force, as the T-shaped plate moves upward... Simultaneously moving upwards, the circular slot plate drives the rotor core, which has been pressed together with the accessories, to move upwards, and the bottom of the pressure block always adheres to the top of the rotor core until the circular slot plate is reset. The T-shaped plate then pulls the telescopic rod to reset. When the center plate drives the U-shaped telescopic frame downwards, the U-shaped telescopic frame drives the clamping arc plate to move synchronously, while the circular slot plate remains stationary due to the support of the spring. At this time, the circular slot plate limits the clamping arc plate, causing the hinge shaft of the U-shaped telescopic frame to start rotating and pushing the clamping arc plate closer to and limited to the outer wall of the rotor core.

[0009] According to the above technical solution, the fastening device includes an L-shaped plate. One side wall of the back of the L-shaped plate is fixedly installed on the outer wall of the circular groove plate. A Z-shaped frame is fixedly installed at the bottom of one side of the back of the L-shaped plate. A crossbar is fixedly installed inside the ventilation slot of the pressing mechanism. A baffle plate is rotatably installed on the outer wall of the crossbar through a torsion spring. The top front of the baffle plate contacts one side of the back of the Z-shaped frame. The circular groove plate drives the L-shaped plate to move downward. The L-shaped plate drives the Z-shaped frame to move synchronously. When the Z-shaped frame moves downward, the limit on the baffle plate is released. At this time, the baffle plate generates a rotational force through the torsion spring. The baffle plate begins to rotate along the outer wall of the crossbar in an arc-shaped trajectory. That is, the top of the baffle plate moves into the pressing mechanism in an arc-shaped trajectory. At this time, the baffle plate opens to cover the ventilation slot of the pressing mechanism.

[0010] According to the above technical solution, a friction wheel is rotatably installed on the back of the L-shaped plate, the outer wall of the friction wheel contacts the inner wall of the pressing mechanism, a threaded rod is fixedly installed through the front of the friction wheel, a trapezoidal block is movably installed through the outer wall of the threaded rod, an elastic telescopic column is slidably installed inside the circular groove plate slide, and an abutment roller is rotatably installed inside the telescopic end of the elastic telescopic column.

[0011] According to the above technical solution, the outer wall of the threaded rod is a non-self-locking threaded groove. The trapezoidal block is slidably mounted on the surface of the L-shaped plate on the side away from the circular groove plate. The end of the elastic telescopic column near the threaded rod is located on the movement trajectory of the trapezoidal block. The outer wall of the contact roller limits the bottom connecting shaft of the rotor core. During the process of the L-shaped plate driving the friction wheel to move downward along the inner wall of the pressing mechanism, friction is generated. The friction wheel starts to rotate due to friction. The friction wheel drives the threaded rod to rotate. The threaded rod is limited by the non-self-locking threaded groove on its own outer wall, driving the trapezoidal block to slide horizontally along the surface of the L-shaped plate. At this time, the inclined surface of the trapezoidal block contacts and abuts the elastic telescopic column, which slides along the inside of the circular groove plate slide. The telescopic end of the elastic telescopic column drives the contact roller to move synchronously. Since the displacement stroke of the elastic telescopic column is shorter than that of the clamping arc plate, the outer wall of the contact roller completes the contact and limitation of the rotor core connecting shaft before the clamping arc plate.

[0012] According to the above technical solution, the anti-deformation device includes a sliding inclined plate, the top of which is fixedly installed at the bottom of the trapezoidal block. The bottom of the sliding inclined plate is located above the internal sliding groove of the pressing mechanism. An arc-shaped frame is horizontally slidably installed on the top of the base by a spring. An elastic push rod is fixedly installed on the top of the base. A support plate is fixedly installed on the top of the telescopic end of the elastic push rod. A shaped plate is fixedly installed on the outer wall of the telescopic end of the elastic push rod.

[0013] According to the above technical solution, the end of the arc frame away from the storage cylinder is located on the inclined plane of the sliding plate. The elastic push rod is telescopic. The bottom of the accessory is located on the top of the support plate. The irregular plate is located inside the vertical groove of the storage cylinder. The bottom of the irregular plate is located on the end of the arc frame away from the trapezoidal block. When the trapezoidal block moves horizontally, it drives the sliding plate to move synchronously. When the sliding plate moves horizontally, its inclined plane contacts and abuts against the outer wall of the arc surface of the arc frame. The abutment of the sliding plate causes the arc frame to slide horizontally along the top of the base. During the movement of the arc frame, it abuts against the bottom arc surface of the irregular plate and supports its bottom. At this time, the irregular plate pushes the telescopic end of the elastic push rod to move upward. The elastic push rod drives the support plate to move towards the bottom of the accessory. At this time, the support plate pushes upward, causing the top of the accessory to slightly detach from the storage cylinder. The support plate supports the bottom of the accessory. After the arc frame is reset, the elastic push rod is reset by the spring force.

[0014] According to the above technical solution, a compression ring is fixedly installed on the top of the irregular plate. The inner wall of the top of the compression ring is designed with an arc surface. A rubber ring is fixedly installed on the outer wall of the top of the storage tube. The outer wall of the rubber ring is located on the movement trajectory of the compression ring. During the upward movement of the compression ring driven by the irregular plate, the arc surface of the top of the compression ring will contact the outer wall of the rubber ring. As the compression ring moves upward, the part of the rubber ring protruding from the top of the storage tube will undergo slight deformation towards the center of the storage tube due to the compression of the inner wall of the compression ring. At this time, the rubber ring fits and limits the top of the accessory around its perimeter.

[0015] This invention provides a press for machining rotor cores. It has the following advantages: (1) The present invention uses an electric slide rail, a T-shaped plate, a telescopic rod, a center plate, a pressure block, a circular groove plate, a support rod, a U-shaped telescopic frame and a clamping arc plate to cooperate. Through the cooperation of the circular groove plate, the support rod and the spring, it is ensured that the top of the rotor core is always in contact with the bottom of the pressure block during the pressing and upward movement of the rotor core, so as to avoid the phenomenon of tipping over due to the vertical posture and reduce the probability of rotor core being damaged by impact. At the same time, the circular groove plate drives the pressed rotor core to move upward, so that the rotor core is reset to the placement position, making it easy for the staff to pick it up. By limiting the outer wall of the rotor core and the top of the pressure block through the clamping arc plate, the rotor core in the vertical posture maintains strong stability during the downward movement and pressing process, ensuring that the rotor core connecting shaft can be vertically and quickly inserted into the accessory.

[0016] (2) The present invention, through the setting of fastening device, through the cooperation of circular groove plate, L-shaped plate, Z-shaped frame, cross bar, baffle plate, friction wheel, threaded rod, trapezoidal block, elastic telescopic column and abutment roller, the Z-shaped frame moves down, causing the baffle plate to open the ventilation groove, that is, during the pressing and mechanical operation, the heat generated inside the pressing mechanism can be quickly discharged, avoiding heat accumulation due to long-term pressing, thereby extending the uninterrupted operation time of the equipment; through the contact and limiting of the abutment roller and the elastic telescopic column, the rotor core connecting shaft can be tightly attached to the inner wall of the center of the circular groove plate, avoiding slight deviation in the placement of the rotor core, thereby causing the bottom end of the connecting shaft to deviate from the top connecting hole of the accessory, avoiding workpiece damage and failure to press due to connection position deviation during the pressing process.

[0017] (3) The present invention, through the setting of the anti-deformation device, through the cooperation of trapezoidal block, sliding inclined plate, arc frame, elastic push rod, support plate, irregular plate, extrusion ring and rubber ring, through the pushing and support of the support plate, promotes the accessory to maintain the vertical posture, while avoiding the connection shaft to be inserted into the accessory. During the process, the top of the accessory with a large area is prevented from being slightly deformed due to the pressure of the connection shaft and contact with the top of the storage cylinder, thus avoiding the deformation of the accessory affecting the transmission effect of the rotor core. The rubber ring is used to fit and limit the top of the accessory around the perimeter, preventing the accessory from shaking slightly due to the insertion of the connection shaft when it is removed from the top of the storage cylinder and pressed. This prevents the bottom outer wall of the accessory from rubbing against the inner wall of the storage cylinder due to shaking, ensuring that the accessory is always pressed in a horizontal posture.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Please see Figures 1-9 One embodiment of the present invention is: a press for processing rotor cores, including a pressing mechanism 1, a base 3 fixedly installed on the bottom of the inner wall of the pressing mechanism 1, a storage cylinder 4 fixedly installed at the center of the top of the base 3, an electric slide rail 5 provided on the back of the inner wall of the pressing mechanism 1, a T-shaped plate 6 slidably installed inside the electric slide rail 5, two telescopic rods 7 symmetrically and fixedly installed at the bottom of the T-shaped plate 6, a center plate 8 penetrating and fixedly installed through the outer wall of the telescopic rods 7, a pressure block 9 penetrating and fixedly installed inside the center plate 8, a circular groove plate 10 fixedly installed at the bottom of the telescopic end of the telescopic rods 7, two support rods 11 symmetrically and fixedly installed at the bottom of the circular groove plate 10, a U-shaped telescopic frame 12 hinged to the outer wall of the center plate 8 by a torsion spring, a fastening device 14 provided around the U-shaped telescopic frame 12 to prevent displacement after the rotor core is connected, an anti-deformation device 15 for supporting the bottom of the pressing parts provided below the fastening device 14, and a clamping arc plate 13 hinged to the bottom of the telescopic end of the U-shaped telescopic frame 12.

[0022] The pressing mechanism 1 has a ventilation slot on its back and a sliding groove at the bottom edge of its inner wall. The pressing mechanism 1 has a safety door 2 on its front. During the pressing process, the bottom end of the rotor core accessory is located inside the storage cylinder 4, and the top surface of the accessory is in contact with the top of the storage cylinder 4. The storage cylinder 4 has a vertical groove inside. The bottom of the pressing block 9 is in contact with the top of the rotor core during the pressing process. The bottom of the rotor core is in contact with the top of the circular groove plate 10, and the bottom connecting shaft of the rotor core is located below the circular groove plate 10.

[0023] The bottom of the pressure block 9 is located below the center plate 8. A slide is provided inside the circular groove plate 10. A spring is provided between the top of the base 3 and the bottom of the circular groove plate 10. The bottom of the support rod 11 moves through the base 3 and the inside of the pressing mechanism 1. The U-shaped telescopic frame 12 is elastically designed. The bottom of the clamping arc plate 13 is slidably installed on the top of the circular groove plate 10. The clamping arc plate 13 limits the outer wall of the rotor core during the pressing process.

[0024] Through the cooperation of the circular slot plate 10, the support rod 11 and the spring, the top of the rotor core is always in contact with the bottom of the pressure block 9 during the pressing and upward movement of the rotor core, which avoids tipping over due to the vertical posture and reduces the probability of the rotor core being damaged by impact. At the same time, the circular slot plate 10 drives the pressed rotor core to move upward, causing the rotor core to return to its placement position for easy handling by the staff. The clamping arc plate 13 limits the outer wall of the rotor core and the top of the pressure block 9, which ensures that the vertical rotor core maintains strong stability during the downward movement and pressing process, ensuring that the rotor core connecting shaft can be vertically and quickly inserted into the accessory.

[0025] In use, the parts to be pressed are placed inside the storage cylinder 4, with the top of the parts at the top of the storage cylinder 4. Then, the bottom connecting shaft of the rotor core is inserted vertically into the center of the circular slot plate 10, with the bottom of the rotor core in contact with the top of the circular slot plate 10. The electric slide rail 5 is activated, which drives the T-shaped plate 6 to move downward. The T-shaped plate 6 drives the telescopic rod 7 to move synchronously, that is, the telescopic rod 7 retracts downward. During the downward movement of the telescopic rod 7 and the center plate 8, the center plate 8 drives the pressure block 9 to move synchronously. At this time, the bottom of the pressure block 9 contacts the top of the rotor core. After the telescopic rod 7 has retracted, the downward pressure of the T-shaped plate 6 causes the telescopic rod 7 to generate a downward force on the circular slot plate 10. At this time, the circular slot plate 10 drives the support rod 11 to penetrate deeper into the pressing mechanism 1. Under the limit of the support rod 11, the circular slot plate 10 is always moved vertically downward. And through the limit of the base 3, the circular slot plate 10 compresses the spring deformation. At this time, the circular slot plate... 10 drives the rotor core closer to the accessory. Under the pressure of the pressure block 9 and the support of the storage cylinder 4, the bottom connecting shaft of the rotor core is inserted into the accessory to complete the pressing work. When the T-shaped plate 6 is reset by the electric slide rail 5, the downward pressure on the circular slot plate 10 is released. At this time, the circular slot plate 10 is pushed by the spring force and moves upward synchronously with the T-shaped plate 6. At this time, the circular slot plate 10 drives the rotor core, which has been pressed with the accessory, to move upward. The bottom of the pressure block 9 is always in contact with the top of the rotor core until the circular slot plate 10 is reset. The T-shaped plate 6 pulls the telescopic rod 7 to reset. When the center plate 8 drives the U-shaped telescopic frame 12 to move downward, the U-shaped telescopic frame 12 drives the clamping arc plate 13 to move synchronously. The circular slot plate 10 is kept stationary by the support of the spring. At this time, the circular slot plate 10 limits the clamping arc plate 13, causing the hinge shaft of the U-shaped telescopic frame 12 to start rotating and pushing the clamping arc plate 13 closer to and limited to the outer wall of the rotor core.

[0026] According to the above embodiment, through the cooperation of the circular groove plate 10, the support rod 11 and the spring, it is ensured that the top of the rotor core is always in contact with the bottom of the pressure block 9 during the pressing and upward movement of the rotor core, so as to avoid the phenomenon of tipping over due to the vertical posture and reduce the probability of rotor core being damaged by impact. At the same time, the circular groove plate 10 drives the pressed rotor core to move upward, so as to reset the rotor core to the placement position, making it easy for the staff to pick it up. By limiting the outer wall of the rotor core and the top of the pressure block 9 through the clamping arc plate 13, the rotor core in the vertical posture maintains strong stability during the downward movement and pressing process, ensuring that the rotor core connecting shaft can be vertically and quickly inserted into the accessory.

[0027] Please see Figures 1-9 Based on the above embodiments, another embodiment of the present invention further includes a fastening device 14; The fastening device 14 includes an L-shaped plate 141. One side wall of the back of the L-shaped plate 141 is fixedly installed on the outer wall of the circular groove plate 10. A Z-shaped frame 142 is fixedly installed at the bottom of one side of the back of the L-shaped plate 141. A crossbar 143 is fixedly installed inside the ventilation slot of the pressing mechanism 1. A baffle plate 144 is rotatably installed on the outer wall of the crossbar 143 through a torsion spring. The top front of the baffle plate 144 contacts one side of the back of the Z-shaped frame 142.

[0028] A friction wheel 145 is rotatably mounted on the back of the L-shaped plate 141. The outer wall of the friction wheel 145 contacts the inner wall of the pressing mechanism 1. A threaded rod 146 is fixedly mounted through the front of the friction wheel 145. A trapezoidal block 147 is movably mounted through the outer wall of the threaded rod 146. An elastic telescopic column 148 is slidably mounted inside the slide of the circular groove plate 10. An abutment roller 149 is rotatably mounted inside the telescopic end of the elastic telescopic column 148.

[0029] The outer wall of the threaded rod 146 is a non-self-locking threaded groove. The trapezoidal block 147 is slidably mounted on the surface of the L-shaped plate 141 on the side away from the circular groove plate 10. The end of the elastic telescopic column 148 near the threaded rod 146 is located on the movement trajectory of the trapezoidal block 147. The outer wall of the contact roller 149 limits the bottom connecting shaft of the rotor core.

[0030] The downward movement of the Z-shaped frame 142 causes the baffle plate 144 to open the ventilation slot, which facilitates the rapid dissipation of heat generated inside the pressing mechanism 1 during pressing and mechanical operation, avoiding heat accumulation due to prolonged pressing and thus extending the continuous operation time of the equipment. The contact roller 149 and the elastic telescopic column 148 contact and limit the rotor core connecting shaft to be tightly attached to the inner wall of the center of the circular groove plate 10, preventing slight deviations in the placement of the rotor core, thus causing the bottom end of the connecting shaft to deviate from the top connecting hole of the accessory, and preventing workpiece damage and pressing failure due to misalignment during pressing.

[0031] In use, the circular groove plate 10 drives the L-shaped plate 141 to move downwards, and the L-shaped plate 141 drives the Z-shaped frame 142 to move synchronously. When the Z-shaped frame 142 moves downwards, it releases the limit on the baffle plate 144. At this time, the baffle plate 144 generates a rotational force through the torsion spring, and the baffle plate 144 begins to rotate along the outer wall of the crossbar 143 in an arc-shaped trajectory. That is, the top of the baffle plate 144 moves into the pressing mechanism 1 in an arc-shaped trajectory. At this time, the baffle plate 144 opens the cover on the ventilation slot of the pressing mechanism 1. During the process of the L-shaped plate 141 driving the friction wheel 145 to move downwards along the inner wall of the pressing mechanism 1, friction is generated. The wheel 145 starts to rotate by friction. The friction wheel 145 drives the threaded rod 146 to rotate. The threaded rod 146 drives the trapezoidal block 147 to slide horizontally along the surface of the L-shaped plate 141 by the limit of the non-self-locking threaded groove on its outer wall. At this time, the inclined surface of the trapezoidal block 147 contacts and abuts the elastic telescopic column 148 and slides along the inside of the slide of the circular groove plate 10. The telescopic end of the elastic telescopic column 148 drives the abutment roller 149 to move synchronously. Since the displacement stroke of the elastic telescopic column 148 is shorter than that of the clamping arc plate 13, the outer wall of the abutment roller 149 completes the contact and limit of the rotor core connecting shaft before the clamping arc plate 13.

[0032] According to the above embodiment, by moving the Z-shaped frame 142 downward, the baffle plate 144 opens the ventilation slot, which facilitates the rapid discharge of heat generated inside the pressing mechanism 1 during pressing and mechanical operation, avoiding heat accumulation caused by prolonged pressing, thereby extending the uninterrupted operation time of the equipment; by the contact and limiting of the contact roller 149 and the elastic telescopic column 148, the rotor core connecting shaft can be tightly attached to the inner wall of the center of the circular groove plate 10, avoiding slight deviations in the placement of the rotor core, thereby causing the bottom end of the connecting shaft to deviate from the top connecting hole of the accessory, avoiding workpiece damage and inability to press due to misalignment during pressing.

[0033] Please see Figures 1-9 Based on the above embodiments, another embodiment of the present invention further includes an anti-deformation device 15; The anti-deformation device 15 includes a sliding inclined plate 151. The top of the sliding inclined plate 151 is fixedly installed at the bottom of the trapezoidal block 147. The bottom of the sliding inclined plate 151 is located above the internal slide groove of the pressing mechanism 1. The top of the base 3 is horizontally slidably installed with an arc frame 152 by a spring. The top of the base 3 is fixedly installed with an elastic push rod 153. The top of the telescopic end of the elastic push rod 153 is fixedly installed with a support plate 154. The outer wall of the telescopic end of the elastic push rod 153 is fixedly installed with a shaped plate 155.

[0034] The end of the curved frame 152 away from the storage tube 4 is located on the inclined plane of the sliding inclined plate 151. The elastic push rod 153 is telescopic. The bottom of the accessory is located on the top of the support plate 154. The irregular plate 155 is located inside the vertical groove of the storage tube 4. The bottom of the irregular plate 155 is located on the end of the curved frame 152 away from the trapezoidal block 147.

[0035] A compression ring 156 is fixedly installed on the top of the irregular plate 155. The inner wall of the top of the compression ring 156 is designed with an arc surface. A rubber ring 157 is fixedly installed on the outer wall of the top of the storage cylinder 4. The outer wall of the rubber ring 157 is located on the movement trajectory of the compression ring 156.

[0036] By using the support plate 154 to push and support the component, the component is kept upright. This prevents the top of the component, which has a large area, from slightly deforming due to the pressure of the connecting shaft against the top of the storage cylinder 4 during the insertion of the connecting shaft. This deformation of the component can affect the transmission effect of the rotor core. The rubber ring 157 fits and limits the top of the component around its perimeter, preventing slight shaking caused by the insertion of the connecting shaft when the component is removed from the top of the storage cylinder 4 and pressed in. This also prevents friction between the bottom outer wall of the component and the inner wall of the storage cylinder 4 due to shaking, ensuring that the component is always pressed in a horizontal position.

[0037] In use, when the trapezoidal block 147 moves horizontally, it drives the sliding inclined plate 151 to move synchronously. When the sliding inclined plate 151 moves horizontally, its inclined surface contacts and abuts against the outer wall of the curved surface of the curved frame 152. Relying on the abutment of the sliding inclined plate 151, the curved frame 152 slides horizontally along the top of the base 3. During the movement of the curved frame 152, it abuts against the bottom curved surface of the irregular plate 155 and supports its bottom. At this time, the irregular plate 155 pushes the extension end of the elastic push rod 153 to move upward. The elastic push rod 153 drives the support plate 154 to move towards the bottom of the accessory. At this time, the support plate 154 pushes upward, causing... The top of the accessory slightly detaches from the storage tube 4, and the support plate 154 supports the bottom of the accessory. After the arc frame 152 returns to its original position, the elastic push rod 153 returns to its original position by the spring force. During the upward movement of the compression ring 156 driven by the irregular plate 155, the top arc surface of the compression ring 156 will contact the outer wall of the rubber ring 157. As the compression ring 156 moves upward, the part of the rubber ring 157 protruding from the top of the storage tube 4 will be slightly deformed towards the center of the storage tube 4 due to the compression of the inner wall of the compression ring 156. At this time, the rubber ring 157 fits and limits the top of the accessory.

[0038] According to the above embodiment, the support plate 154 pushes and supports the accessory to keep it upright while preventing the top of the accessory, which has a large area, from slightly deforming due to the pressure of the connecting shaft against the top of the storage cylinder 4 during the insertion of the connecting shaft. This prevents the deformation of the accessory from affecting the transmission effect of the rotor core. The rubber ring 157 fits and limits the top of the accessory around its perimeter, preventing slight shaking caused by the insertion of the connecting shaft when the accessory is removed from the top of the storage cylinder 4 and pressed in. This also prevents the bottom outer wall of the accessory from rubbing against the inner wall of the storage cylinder 4 due to shaking, ensuring that the accessory is always pressed in a horizontal position.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
