A third motor 9 is mounted on the feed seat 7 to provide power for the rotation of the saw blade 8. A feed driver 10 is mounted on the support frame 6 to provide power for the feed of the feed seat 7. Furthermore, the first motor 4 is a brake stepper motor; the second motor 5 is a speed-regulating motor that can rotate 360 ​​degrees in both directions; the feed driver 10 is a telescopic cylinder, or it can be a mechanical slide table, etc.; a guide rod is mounted on the feed seat 7, and the guide rod is slidably mounted on the support frame 6.

[0029] For details, please refer to Figure 1 and Figure 3 The clamping mechanism includes a jaw 18 hinged to the placement platform 3 and a second drive cylinder 19. The second drive cylinder 19 is hinged to the placement platform 3, and its output end is hinged to the jaw 18. The second drive cylinder 19 can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0030] For details, please refer to Figure 1 It also includes an open chip collection trough 20, which is located below the placement platform 3.

[0031] In the aluminum alloy wheel hub trimming machine provided in this embodiment, when the output end of the second drive cylinder 19 shortens, the chuck 18 moves away from the center of the placement platform 3. When the wheel hub needs to be secured, the output end of the second drive cylinder 19 extends, and the chuck 18 on each clamping mechanism secures the wheel hub to the center of the placement platform 3. The open chip collection trough 20 can collect the falling ring tail material and metal chips for subsequent centralized cleaning.

[0032] Example 2

[0033] The aluminum alloy wheel hub trimming machine provided in Example 1 has been further optimized. For details, please refer to [link / reference]. Figure 3-4 It also includes a base frame 11, a lifting drive 12 mounted on the base frame 11, and a conveyor 13; the conveyor 13 is mounted on the lifting drive 12 and is used for receiving and feeding materials from the hub; furthermore, the lifting drive 12 is preferably a telescopic cylinder, but the lifting drive 12 can also be other equivalent components with lifting and feeding effects, and the conveyor 13 can be a chain roller conveyor or a belt conveyor.

[0034] For details, please refer to Figure 2 A limit stop 14 is installed on the conveyor 13. The limit stop 14 is used to limit and block the wheel hub. Furthermore, the limit stop 14 adopts a V-shaped opening stop bar, and the middle part of the limit stop 14 is provided with an arc-shaped part that fits with the outer wall of the wheel hub.

[0035] For details, please refer to Figure 3 or Figure 4 An electromagnetic ring 15 is installed at the bottom of the conveyor 13 corresponding to the placement platform 3. A first drive cylinder 16 is installed on the conveyor 13 to provide power for the up and down movement of the electromagnetic ring 15. Furthermore, the first drive cylinder 16 can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0036] For details, please refer to Figure 3 or Figure 4 A rotary drive table 17 is mounted on the lifting drive 12, and a conveyor 13 is mounted on the rotary drive table 17. Furthermore, the rotary drive table 17 can be a mechanical rotary drive table or a pneumatic turntable.

[0037] Please refer to the aluminum alloy wheel hub trimming machine provided in this embodiment. Figure 4The wheel hub can be conveyed to the bottom of the placement table 3 via conveyor 13. The limiting stop 14 limits and blocks the wheel hub, precisely positioning its loading position. Then, the lifting drive 12 drives the conveyor 13 upwards until the top of the wheel hub contacts the bottom of the placement table 3. The clamping mechanism then secures the outer wall of the wheel hub, achieving automatic and precise loading, improving mechanization, and further reducing manual operation. Similarly, the conveyor 13 can receive and unload processed wheel hubs. The rotary drive table 17 drives the conveyor 13 to rotate, transporting the wheel hub to the next processing equipment in the desired direction. Please refer to [reference needed]. Figure 3 During the wheel hub trimming process, the output end of the first drive cylinder 16 extends, and the electromagnetic ring 15 moves downward. After the electromagnetic ring 15 is energized, it has an upward adsorption effect on the ring tail material after circumferential cutting, so that there is a certain gap between the cut ring tail material and the saw blade 8, reducing the friction between the ring tail material and the saw blade 8. At the same time, under the attraction of the electromagnetic ring 15, the cut ring tail material can be prevented from being thrown out at high speed under the centrifugal force of the saw blade 8, reducing the mechanical injury accident rate and improving operational safety. When the L-shaped boom 2 moves above the conveyor 13, the electromagnetic ring 15 is de-energized, and the ring tail material falls into the open chip collection trough 20 under the action of gravity. The energized electromagnetic ring 15 can also adsorb metal chips to reduce the metal chips being thrown out in all directions by the saw blade 8, ensuring a clean working environment.

[0038] The aluminum alloy wheel hub trimming machine provided by this utility model is used as follows: The wheel hub is placed on the conveyor 13 and transported to the limit stop 14 by the conveyor 13. The lifting driver 12 drives the conveyor 13 to move upward until the top of the wheel hub is in close contact with the bottom of the placement platform 3. The clamping mechanism clamps the outer wall of the wheel hub. The lifting driver 12 drives the conveyor 13 to move downward. The first motor 4 drives the L-shaped boom 2 to rotate to the position as described above. Figure 3 In the indicated state, the feed driver 10 drives the feed seat 7 to feed, the third motor 9 drives the saw blade 8 to rotate at high speed, and the second motor 5 drives the placement table 3 to rotate 360 ​​degrees. The saw blade 8 performs a circumferential cut on the upper edge of the hub on the placement table 3. The circumferential cut tail material and metal debris are attracted by the electromagnetic ring 15. The first motor 4 drives the L-shaped boom 2 to rotate 180 degrees. Figure 4 In the state shown, the electromagnetic ring 15 is de-energized. Under the action of gravity, the tail material of the ring, the metal debris adsorbed by the electromagnetic ring 15, and the metal debris at the placement platform 3 fall into the open chip collection trough 20. The trimmed wheel hub falls back to the conveyor 13 and is then transported to the next processing unit by the conveyor 13.
