Description

Technical Field

[0001] This application relates to the field of wheel hub induction heating equipment technology, and in particular to a chuck-type stepless variable speed flexible disk. Background Technology

[0002] The core heating principle of the wheel hub induction heating equipment is as follows: a magnetic field is formed by an optimized arrangement of permanent magnets. When the permanent magnets rotate, a rotating magnetic field is generated. The wheel hub cuts the magnetic induction lines to form eddy currents and generate heat, thereby completing the heating of the wheel hub. The flexible disk is the core key component for realizing this heating process.

[0003] In existing technologies, flexible disks are cumbersome to operate during locking and gear shifting, and can only change to fixed gears. As the demand for wheel hub heating adaptation increases, the need for gear shifting continues to grow, further causing the limited gears of existing flexible disks to be unable to adapt to more wheel hub heating models. Summary of the Invention

[0004] This application provides a chuck-type stepless variable gear flexible disk to solve the technical problems of existing flexible disks, such as complex structure, only able to change fixed gears, unsmooth gear changes, and high installation and maintenance costs. It realizes stepless adjustment of the diameter of the disk magnet assembly, improving the flexibility and efficiency of hub induction heating.

[0005] This application provides a chuck-type stepless variable speed flexible disk, including a chuck body, a rotating disk, multiple chuck slots, and multiple magnets.

[0006] The chuck body contains a cavity, and its end face has multiple circumferentially distributed guide channels, each extending radially along the chuck body. A rotating disk is disposed within the cavity, and its end face has coiled wires arranged in an Archimedean spiral pattern, spiraling uniformly outward from the center of the rotating disk. A corresponding chuck holder is disposed within each guide channel, slidingly engaging with the guide channel. A groove is formed on the end face of the chuck holder near the rotating disk, engaging with the coiled wires. Magnets are correspondingly disposed on the chuck holders. The rotating disk, by rotating, can move the chuck holders and magnets outward or inward along the guide channels, thereby adjusting the disk radius.

[0007] In one possible design, a drive bevel gear is installed in the disk cavity. The axle of the drive bevel gear is arranged radially, and helical teeth are provided on the other end face of the rotating disk. The drive bevel gear drives the rotating disk to rotate by meshing with the helical teeth.

[0008] In one possible design, a driven bevel gear is also installed in the disk cavity. The axle of the driven bevel gear is arranged radially. The driven bevel gear and the driving bevel gear are arranged in a ring. The driven bevel gear meshes with the helical teeth on the rotating disk, so that the rotating disk is movably supported on the driving bevel gear and the driven bevel gear, ensuring the structural stability of the rotating disk during rotation.

[0009] In one possible design, the rotating disk is annular, and the disk cavity is also annular, which adapts to the installation and rotation requirements of the rotating disk, while optimizing the overall structural layout of the disk.

[0010] In one possible design, mounting holes are provided on the outer ring wall of the chuck cavity, and the large ends of the driving bevel gear and the driven bevel gear are respectively formed with cylindrical extensions. The extensions pass through the mounting holes to achieve the positioning and installation of the bevel gears on the chuck body.

[0011] In one possible design, an annular groove is formed on the extension section to reduce the friction between the surface of the extension section and the inner wall of the mounting hole, thereby improving the flexibility of the bevel gear rotation.

[0012] In one possible design, the flexible disk also includes a driver connected to the axle of an active bevel gear for driving the active bevel gear to rotate around the axle, thereby providing power for the rotation of the disk.

[0013] In one possible design, a clearance hole is formed in the center of the chuck body, the drive is set at the clearance hole, and a shaft hole is opened on the inner ring wall of the chuck cavity. The shaft of the drive bevel gear passes through the shaft hole and connects to the output end of the drive, making reasonable use of the central space of the chuck body and optimizing the power transmission structure.

[0014] In one possible design, the flexible disk also includes a base and a magnetic base. The disk body is mounted on the base, providing support and a fixed foundation for the entire disk. The magnet is mounted on the magnetic base to achieve stable fixation of the magnet. At the same time, through the connection between the magnetic base and the disk, the magnet moves synchronously with the disk.

[0015] In one possible design, the flexible disk also includes a displacement sensor mounted on the base. The displacement sensor is used to collect the radial displacement of the card slot, enabling accurate detection and feedback of the magnet position.

[0016] In one possible design, the drive is preferably a pneumatic motor with an integrated reducer, which can generate a large torque. When the pneumatic motor is not rotating, the disk can remain locked. The displacement sensor is preferably a pull-rope displacement sensor, which can feed back the collected disk displacement signal to the PLC calculator of the permanent magnet heating device to achieve precise locking and changing of disk positions.

[0017] The chuck body is bolted to the base, which is also bolted to an external connecting seat. The connecting seat serves as the base for bearing the weight of the chuck and fixing the motor shaft of the connecting equipment. The pneumatic motor is locked to the base by bolts through a motor locking plate. The output end of the pneumatic motor is fixedly connected to the axle of the drive bevel gear through a coupling to ensure stable torque transmission. The magnetic base and the chuck base, as well as the magnet and the magnetic base, are bolted to ensure the firmness of the connection and the synchronicity of motion transmission.

[0018] The beneficial effects of this application are as follows: The chuck-type stepless variable-gear flexible disk of this application achieves stepless adjustment of the diameter of the magnet assembly through the cooperation of the chuck body, rotating disk and chuck seat. It breaks through the limitation of existing technology that can only change fixed gears. It can flexibly adjust the heating air gap between the magnet and the wheel hub. The operator can accurately control the heating efficiency and production cycle according to the actual production needs, and adapt to the preheating operation of wheel hub spinning with different specifications and heating requirements.

[0019] The shifting process is smooth and stable. Through the meshing transmission of the driving bevel gear, driven bevel gear and rotating disk, the caliper slides smoothly in the radial direction. The driven bevel gear provides effective support for the rotating disk, ensuring the structural stability of the overall movement. In addition, the annular groove of the bevel gear extension section reduces rotational friction, further improving the smoothness of shifting. Attached Figure Description

[0023] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The following is combined with Figures 1-6 This describes the chuck-type infinitely variable flexible disk provided in the embodiments of this application.

[0025] The chuck-type continuously variable flexible disk provided in this embodiment is applied to a wheel hub induction heating device for preheating wheel hub spinning. (Refer to...) Figures 1-5 As shown, the chuck-type stepless variable speed flexible disk includes a magnet 1, a magnetic base 2, a chuck base 3, a chuck body 4, an active bevel gear 91, a driven bevel gear 92, and a rotating disk 10.

[0026] The chuck body 4 forms an annular cavity 41. The end face of the chuck body 4 is provided with multiple guide channels 42 that are evenly distributed in the circumferential direction. The guide channels 42 extend radially along the chuck body 4. The guide channels 42 are I-shaped grooves. The lower end of the guide channels 42 is connected to the cavity 41.

[0027] There are multiple card holders 3, and each card holder 3 corresponds to a guide channel 42. The end face of the card holder 3 is I-shaped and slides with the I-shaped guide channel 42, restricting the card holder 3 to move only radially along the chuck body 4.

[0028] The rotating disk 10 has an annular structure and is disposed in the annular cavity 41 of the chuck body 4. The upper end face of the rotating disk 10 has coiled wires arranged in an Archimedean spiral pattern, which are uniformly wound outward from the center of the rotating disk 10. The chuck seat 3 has a slot on its end face near the rotating disk 10, and the slot engages with the coiled wires of the rotating disk 10.

[0029] The lower end face of the rotating disk 10 is provided with helical teeth 13. The disk cavity 41 is circumferentially distributed with a driving bevel gear 91 and a plurality of driven bevel gears 92. The axles of the driving bevel gear 91 and the driven bevel gears 92 are both arranged radially and mesh with the helical teeth 13 on the lower end face of the rotating disk 10. The driving bevel gear 91 and the driven bevel gears 92 together form a movable support for the rotating disk 10, ensuring the stability of the rotation of the rotating disk 10.

[0030] The outer annular wall of the disk cavity 41 is provided with a plurality of mounting holes 43. The large end of the bevel gear is formed with a cylindrical extension section, which passes through the mounting holes 43 for supporting the bevel gear. In some embodiments, an annular groove is provided on the extension section, which is used to reduce the friction between the extension section and the inner wall of the mounting hole 43 and improve the rotational flexibility of the bevel gear.

[0031] A clearance hole is provided in the center of the chuck body 4, and the driver 7 is located at the clearance hole. The driver 7 is a pneumatic motor. A shaft hole is provided on the inner ring wall of the disc cavity 41. The shaft of the drive bevel gear 91 passes through the shaft hole and is fixedly connected to the output end of the pneumatic motor through the coupling 8. The pneumatic motor is locked and fixed to the bolt and the base 5 through the motor locking plate 11, providing torque for the rotation of the drive bevel gear 91.

[0032] The base 5 and the chuck body 4 are axially connected and fixed by bolts. The upper end face of the base 5 is provided with an upper annular groove 51 and the lower end face is provided with a lower annular groove 52. The lower end face of the chuck body 4 is formed with an annular protrusion. The base 5 and the chuck body 4 are circumferentially limited by the annular protrusion and the upper annular groove 51.

[0033] The base 5 and the connecting seat 6 are axially connected and fixed by bolts. The base 5 and the connecting seat 6 are also circumferentially limited by the lower annular groove 52 and the outer ring wall of the connecting seat 6. The connecting seat 6 serves as the load-bearing foundation of the entire disk and is also used to connect the motor shaft of the drive motor at the bottom of the hub induction heating device.

[0034] Specifically, the bolts include multiple bolts arranged circumferentially. Each bolt passes through the inner ring wall of the connecting seat 6, the base 5, and the chuck body 4 sequentially from bottom to top along the axial direction. Thus, the bolts can connect the connecting seat 6, the base 5, and the chuck body 4 together, further improving the stability of the flexible disk structure.

[0035] The magnetic base 2 and the card holder 3 are fixed together by bolts. The card holder 3 has a waist-shaped groove 31, and the lower end of the magnetic base 2 has a waist-shaped protrusion 21. The magnetic base 2 and the card holder 3 are circumferentially positioned by the waist-shaped groove 31 and the waist-shaped protrusion 21. The magnet 1 and the magnetic base 2 are axially fixed together by bolts, so as to achieve stable installation of the magnet 1 and ensure that the radial movement of the card holder 3 can synchronously drive the magnetic base 2 and the magnet 1 to move radially. In this way, the stability and reliability of the flexible disk structure can be effectively improved, and it can be used to counteract the centrifugal force and overturning torque when the magnet rotates at high speed.

[0036] The pull rope displacement sensor 12 is installed on the base 5 to collect the radial displacement signal of the card holder 3 and feed the signal back to the PLC calculator of the hub induction heating equipment. Together with the driver 7, it realizes the accurate detection of the position of the magnet 1 and the automatic control of the disk gear.

[0037] The working process of the chuck-type continuously variable flexible disk in this application is as follows: Start the pneumatic motor, which transmits torque to the drive bevel gear 91 through coupling 8, driving the drive bevel gear 91 to rotate around the wheel shaft; The driving bevel gear 91 meshes with the helical teeth on the lower end face of the rotating disk 10, causing the rotating disk 10 to rotate around its own axis in the disk cavity 41. At the same time, multiple driven bevel gears 92 meshing with the rotating disk 10 rotate synchronously with the rotation of the rotating disk 10, forming a stable support for the rotating disk 10 and ensuring its smooth rotation. When the rotating disk 10 rotates, the Archimedes spiral coil on its upper end face meshes with the slot of the card holder 3, causing multiple card holders 3 to slide outward or inward synchronously along the radial guide channel 42 of the chuck body 4. The radial sliding of the card holder 3 drives the magnetic seat 2 bolted to it and the magnet 1 bolted to the magnetic seat 2 to move radially in sync, thereby realizing stepless adjustment of the diameter of the disk magnet assembly and adjusting the heating air gap between the magnet 1 and the hub. The pull rope displacement sensor collects the radial displacement signal of the card holder 3 in real time and feeds the signal back to the PLC calculator. When the magnet 1 moves to the target position, the PLC calculator controls the pneumatic motor to stop rotating. The pneumatic motor has a reducer that can generate a large torque. After the pneumatic motor stops, the disk is directly locked, completing the gear change. When the hub induction heating equipment is working, the motor shaft of the drive motor at the bottom of the hub induction heating equipment drives the entire flexible disk to rotate through the connecting seat 6. The rotating magnetic field formed by the magnet 1 causes the hub to cut the magnetic induction lines, generate eddy currents and heat up, and realize the preheating of the hub spinning. The operator can adjust the diameter of the magnet group again according to the heating requirements through the above steps to adapt to different specifications of hubs, thereby effectively improving heating efficiency and production cycle.

[0038] This application's chuck-type stepless variable-gear flexible disk achieves stepless adjustment of the magnet assembly diameter through the cooperation of the chuck body, rotating disk, and chuck base. This overcomes the limitation of existing technologies that can only change fixed gears, allowing for flexible adjustment of the heating air gap between the magnet and the hub. Through the meshing transmission of the driving bevel gear, driven bevel gear, and rotating disk, the chuck base slides smoothly radially. The driven bevel gear provides effective support for the rotating disk, ensuring structural stability during overall movement. Furthermore, the annular groove in the bevel gear extension reduces rotational friction, further improving the smoothness of gear shifting.
