Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical processing, in particular to a press for rotor core processing. BACKGROUND

[0002] The rotor core is one of the core components in rotating machines such as motors and generators, and its main function is to support the rotor coil 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 in the center of the rotor core. The rotor core is shaped by a press during processing.

[0003] The patent with the patent number CN220444876U discloses a press for rotor core processing, which includes 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 installed on the top surface of the fixed support assembly, and a sliding mechanism is installed on the core guide assembly. The core drive assembly is located on one side of the core guide assembly. The bottom of the core positioning assembly is installed on the core guide assembly through the sliding mechanism. The bottom of the core shaping assembly is installed on the top surface of the fixed support assembly. The patent has a core positioning assembly, which includes a fixed seat and a positioning part. The positioning part is installed on the fixed seat and includes a positioning shaft and a placement column. The positioning shaft and the placement column are coaxially arranged. The rotor core is positioned by the positioning shaft, and the bottom surface of the rotor core contacts the top surface of the placement column to position and support the rotor core, improving the stability of the rotor core.

[0004] However, the device still has some shortcomings. The device relies on the positioning shaft to position and press the rotor core. However, since the rotor core bottom accessory is located at the positioning shaft, the vertical rotor core is prone to tilting after the rotor core is pressed and loses the resistance of the top pressing mechanism. At this time, the staff needs to hold or use external equipment to assist in supporting, which increases the probability of damage to the rotor core and the work intensity of the staff. SUMMARY

The circular groove plate drives the L-shaped plate to move downward, the L-shaped plate drives the Z-shaped frame to move synchronously, the Z-shaped frame moves downward, the shielding plate is released from the limitation, at this time, the shielding plate is rotated by the torsion spring, the shielding plate starts to flip along the outer wall of the horizontal rod in an arc track, that is, the top of the shielding plate moves in an arc track to the inner part of the pressing mechanism, at this time, the shielding plate is opened to shield the ventilation groove 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.

[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.

During the upward movement of the special-shaped plate and the extrusion ring, the arc-shaped top of the extrusion ring is in contact with the outer wall of the rubber ring. With the upward movement of the extrusion ring, the part of the rubber ring protruding from the top of the storage cylinder is slightly deformed towards the center of the storage cylinder due to the extrusion of the inner wall of the extrusion ring. At this time, the rubber ring is in close contact with and limited to the top of the accessory.
