Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing technology, specifically to an auxiliary deburring device for aluminum alloy wheel hubs. Background Art

[0002] Aluminum alloy wheels, also commonly known as aluminum rims, are the outer frame of car wheels made of aluminum alloy. They work in conjunction with tires to bear the weight of the vehicle and transmit various forces. Compared to steel wheels, aluminum alloy wheels have many advantages and are therefore widely used in various passenger cars, light commercial vehicles, and some high-performance sports cars.

[0003] Traditional aluminum alloy wheel processing requires drilling holes in the wheel surface. After drilling, burrs will appear on the edges and inside the holes, which need to be removed manually with tools. However, this process requires rotating the wheel to process the holes at different locations. Furthermore, when the wheel is being transported, its axis is vertical. When removing burrs, the axis needs to be converted to a horizontal direction to facilitate the removal. This requires manual handling of the wheel, resulting in excessive labor intensity and low processing efficiency.

[0004] Therefore, in order to address the above problems, an auxiliary deburring device for aluminum alloy wheel hubs is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1-4 As shown, this utility model provides a technical solution:

[0027] A deburring auxiliary device for aluminum alloy wheel hubs includes: a turntable base 1 with a turntable mounting hole 2 extending through it; a wheel hub turntable 3 rotatably mounted on the turntable mounting hole 2 to hold the wheel hub; a chip removal hole 4 extending through the center of the wheel hub turntable 3 to facilitate the falling of scraped burr debris from the turntable 3; a roller 5 rotatably mounted inside the chip removal hole 4 to support the wheel hub; a chip removal box 6 below the chip removal hole 4 with an opening at the top, the opening size being no smaller than the bottom end size of the chip removal hole 4; the chip removal box 6 can be removed from the bottom of the turntable base 1 for easy transfer and processing of debris; a rotating assembly 7 mounted on the turntable base 1, connected to the wheel hub turntable 3, for driving the wheel hub turntable 3 to rotate, thereby changing the angle and position of the wheel hub; the turntable base 1... A loading platform 8 and a discharging platform 9 are respectively set on both sides. The loading platform 8, the turntable 1 and the discharging platform 9 are arranged along the hub conveying direction, that is, the hub moves along the loading platform 8, the turntable 1 and the discharging platform 9. A translational seat 10 is set on both sides of the arrangement direction. A moving frame 11 is slidably set on the translational seat 10. The sliding direction of the moving frame 11 is parallel to the hub conveying direction. A lifting plate 12 is slidably set on the moving frame 11. The lifting plate 12 can move up and down. A clamping frame 13 is slidably set on the lifting plate 12. The sliding direction of the clamping frame 13 is perpendicular to the hub conveying direction and the lifting direction of the lifting plate 12. A clamping component 14 is rotatably set at the end of the clamping frame 13 near the hub. The clamping components 14 on both sides are used to cooperate to clamp the hub.

[0028] In this embodiment, several receiving grooves 21 are circumferentially opened on the outer edge of the turntable mounting hole 2. Rolling balls are rolled in the receiving grooves 21. The rolling balls contact the hub turntable 3 to reduce the friction between the hub turntable 3 and the turntable base 1 when the hub turntable 3 rotates, thereby extending the service life of the device and improving its economy.

[0029] In this embodiment, the inner wall of the chip removal hole 4 is inclined, making the chip removal hole 4 a funnel-shaped conical hole. When burr debris falls into the chip removal hole 4, it can slide quickly down the inclined inner wall, avoiding debris accumulation that affects the use of the device and improving the practicality of the device. At least two rollers 5 are provided, and the axes of the rollers 5 are arranged parallel to each other in the chip removal hole 4 of the hub turntable 3. The outer surface of the rollers 5 is covered with a flexible layer, which is made of rubber. This avoids damage to the edge of the hub and increases the friction between the hub and the rollers 5, improving stability. Preferably, one end of one of the rollers 5 is connected to a small motor to drive the hub to rotate, replacing manual rotation of the hub and improving the safety and efficiency of deburring.

[0030] In this embodiment, the rotating assembly 7 includes a worm gear 71, which is coaxially disposed at the bottom of the hub turntable 3. The worm gear 71 can drive the hub turntable 3 to rotate and is meshed with a worm 72. The worm 72 is rotatably disposed on the turntable base 1. One end of the worm 72 is connected to a motor, which drives the worm 72 to rotate, thereby causing the worm gear 71 to rotate and driving the hub turntable 3 to rotate. Preferably, the worm gear 71 is replaced by a large gear and the worm 72 is replaced by a small gear. The large gear and the small gear are meshed and connected. The small gear is coaxially connected to the output end of the motor, which can achieve the same effect but at a lower cost, thus improving economic efficiency.

[0031] In this embodiment, both the loading platform 8 and the unloading platform 9 are equipped with several rotating rollers 81 with parallel axes. The axes of the rotating rollers 81 are perpendicular to the conveying direction of the hub and are arranged along the conveying direction of the hub. This is used to reduce the friction between the hub and the surfaces of the loading platform 8 and the unloading platform 9 during the conveying process, and to prevent damage to the hub. More preferably, the loading platform 8 and the unloading platform 9 can be made of commercially available roller conveyor belts, which is more practical.

[0032] In this embodiment, a lead screw 101 is rotatably mounted on the translational seat 10. The axis of the lead screw 101 is parallel to the hub conveying direction. One end of the lead screw 101 is connected to the second motor. The lead screw 101 is threadedly connected to the moving frame 11 to drive the moving frame 11 to move the hub on the loading platform 8 to the turntable seat 1 and to move the processed hub on the turntable seat 1 to the unloading platform 9, thereby reducing the labor intensity of the operators.

[0033] In this embodiment, a guide plate 111 and a lead screw 112 are provided on the movable frame 11. The axis of the lead screw 112 is parallel to the length direction of the guide plate 111 and perpendicular to the ground. A lifting plate 12 is slidably sleeved on the guide plate 111, and the lead screw 112 is threadedly connected to the lifting plate 12. One end of the lead screw 112 is connected to a motor 3, which is used to drive the lifting plate 12 to move up and down to lift the hub and avoid interference from the loading platform 8 when the hub rotates as a whole, thus improving the practicality of the device.

[0034] In this embodiment, a motor four is provided on the lifting plate 12, and a drive gear one 121 is coaxially provided on the output end of the motor four. A rack 122 is provided on the clamping frame 13. The length direction of the rack 122 is perpendicular to the wheel hub conveying direction and the moving direction of the lifting plate 12, and the rack 122 is meshed with the drive gear one 121 so that the clamping components 14 are close to each other to achieve clamping of the wheel hub. It can be applied to clamping wheel hubs of different diameters, thus improving the applicability of the device.

[0035] In this embodiment, the clamping assembly 14 includes a clamping support frame 141. The clamping support frame 141 is rotatably mounted on the end of the clamping frame 13 near the hub via a rotating shaft 142, and the axis of the rotating shaft 142 is parallel to the length direction of the rack 122. A left clamping plate 143 and a right clamping plate 144 are provided on the clamping support frame 141. Both the left clamping plate 143 and the right clamping plate 144 are arc-shaped plates. One end of the left clamping plate 143 and the right clamping plate 144 is rotatably mounted on the clamping support frame 141. Both the left clamping plate 143 and the right clamping plate 144 are connected to the clamping support frame via a telescopic member 145. 141. The telescopic component 145 can be a small cylinder. Both ends of the telescopic component 145 are rotatably connected to the clamping support frame 141, the left clamping plate 143, and the right clamping plate 144. The telescopic component 145 can change the angle between the left clamping plate 143 and the right clamping plate 144 by telescoping to adapt to the clamping of wheel hubs of different diameters. Preferably, the surfaces of the left clamping plate 143 and the right clamping plate 144 that contact the wheel hub are provided with a flexible rubber layer to better adapt to the clamping of wheel hubs of different diameters, so that the contact is more sufficient, the friction is increased, and the stability and safety of the device are improved.

[0036] In this embodiment, a driven gear 131 is coaxially arranged on the rotating shaft 142. The driven gear 131 meshes with the driving gear 132. The driving gear 132 is coaxially connected to the motor 5. The motor 5 is arranged on the clamping frame 13 and is used to drive the clamping assembly 14 to rotate, so as to change the wheel hub from a flat state to a vertical state, making it convenient to place the wheel hub on the wheel hub turntable 3. This replaces the manual movement and flipping of the wheel hub, improving the processing efficiency and the practicality of the device.

[0037] Working principle: First, the wheel hub is loaded from the loading platform 8. When it moves close to the turntable 1, the conveying stops. The moving frame 11 moves to the position corresponding to the wheel hub, and the lifting plate 12 moves to the position where the clamping assembly 14 is at the same height as the wheel hub. The left clamping plate 143 and the right clamping plate 144 are opened. The clamping frame 13 is moved so that the left clamping plate 143 and the right clamping plate 144 are in contact with the outer surface of the wheel hub and clamped. Then, the lifting plate 12 is moved to lift the wheel hub away from the loading platform 8 and move it directly above the wheel hub turntable 3. The wheel hub turntable 3 is rotated so that the axis of the roller 5 is parallel to the direction of wheel hub movement. The clamping support frame 141 is rotated. The hub is rotated 90 degrees, changing its axis from being perpendicular to the loading platform 8 to being parallel to the loading platform 8, i.e., parallel to the axis of the roller 5. Then, the lifting plate 12 is lowered, placing the hub on the roller 5. The clamping assembly 14 is then released, allowing the hub to roll freely on the roller 5. The operator then performs a deburring operation on the hub. After deburring, the hub is clamped again by the clamping assembly 14. The hub is then lifted and rotated 90 degrees in the opposite direction, returning it to its loading state. The hub is then moved and placed on the discharge platform 9, the clamping assembly 14 is released, and the hub is conveyed to the next station.
