[0030] The working steps of this embodiment are as follows: Before using this device, first the operator pulls the push-pull hatch 2 to the left to open it, so that the push-pull hatch 2 is in a folded state. Then the operator pastes and fixes the grinding disc 9 on the upper part inside the inner lining ring 12, and pastes and fixes the polishing disc 11 on the lower part inside the inner lining ring 12. Then the operator transfers the hub body 001 to the machine tool body 1. The operator unscrews the fixing nut 1004 from the rotating rod 1002, and then inserts the middle part of the hub body 001 into the rotating rod 1002. The rotating rod 1002 penetrates through the hub body 001 until the hub body 001 touches the limit disc 1003. Then the operator screws the fixing nut 1004 back onto the rotating rod 1002 and simultaneously fixes the hub body 001 in cooperation with the limit disc 1003 as Figure 2 shown. The operator closes the push-pull hatch 2 to the right. The push-pull hatch 2 is made of transparent material, and the operator can observe the processing process of the hub body 001 through the push-pull hatch 2. Then the operator sets the processing program on the touch screen on the right side of the machine tool body 1. Then the machine tool body 1 starts the processing process of the hub body 001. First, it controls the two electric sliders 5 to move towards the hub body 001, synchronously driving the first electric actuator 6 and its corresponding components to move together. When the fixing ring 8 moves to the position of the hub body 001, it stops, as Figure 2 shown. At this time, the grinding disc 9 is located above the hub body 001. Control the two first electric actuators 6 to contract, synchronously driving a rotating shaft 7 and its corresponding components to move downward until the grinding disc 9 touches the hub body 001. Then control the driving motor 1001 of the machine tool body 1 to start. The output shaft of the driving motor 1001 rotates, synchronously driving the rotating rod 1002 and its corresponding components to rotate, thereby causing the hub body 001 to rotate. Looking from right to left, the hub body 001 rotates counterclockwise. During the rotation of the hub body 001, it is always in contact with the grinding disc 9, realizing the grinding of the outer ring surface of the hub body 001 by the grinding disc 9. By extending and contracting the first electric actuator 6, the contact pressure between the grinding disc 9 and the hub body 001 is controlled, thereby adapting to different grinding requirements of the hub body 001 and the grinding work of hub bodies 001 of different sizes. Also, by controlling the movement of the electric slider 5 on the electric slide rail 4, the contact position of the grinding disc 9 on the hub body 001 is changed, thereby realizing the full grinding of the outer ring surface of the hub body 001.

[0031] After the grinding of the hub body 001 is completed, it is also necessary to polish its surface. At this time, control the rotation of the hub body 001 to stop, and then control the two first electric actuators 6 to extend, so that the fixing ring 8 and its components move upward until the fixing ring 8 is in a coaxial position with the hub body 001. Then control the two electric sliders 5 to move to the right, synchronously driving the fixing ring 8 and its components to move to the right. The distance that the electric slider 5 moves to the right is greater than the radius length of the fixing ring 8. Thus, when the fixing ring 8 rotates, the fixing ring 8 actively avoids the hub body 001 to prevent contact between the fixing ring 8 and the hub body 001. Then control the first motor 10 to start. The output shaft of the first motor 10 rotates, synchronously driving the rotating shaft 7 and its corresponding components to rotate 180 degrees, so that the polishing disc 11 rotates above the grinding disc 9. Among them, during the grinding process of the hub body 001, the aluminum powder that falls on the polishing disc 11 drops from the polishing disc 11 during the rotation of the fixing ring 8, realizing the automatic cleaning of the polishing disc 11. Then repeat the operation of grinding the hub body 001, and use the polishing disc 11 to directly perform fine polishing on the hub body 001, thus avoiding the need in the prior art to polish the hub body 001 in another polishing device. Therefore, it is necessary to transfer the semi-finished hub body 001, which will not only reduce the processing efficiency but also require a large amount of funds to purchase additional polishing equipment, increasing the production cost.

[0032] Considering that the outer ring surface of the hub body 001 is not a conventional cylindrical shape, the width of the inner lining ring 12 is set to be smaller than the widths of the grinding disc 9 and the polishing disc 11. Since both the grinding disc 9 and the polishing disc 11 are made of flexible materials, when encountering large-angle warping, the grinding disc 9 and the polishing disc 11 can turn up and deform, so that the grinding disc 9 and the polishing disc 11 are close to the grinding and polishing positions. For small-angle warping, control the first motor 10 to start. The output shaft of the first motor 10 rotates, causing the fixing ring 8 and its components to rotate, thereby realizing the deflection of the grinding disc 9 and the polishing disc 11, and further realizing the full grinding and polishing treatment of the outer ring surface of the hub body 001.

[0033] It should also be taken into account that when the grinding disc 9 and the polishing disc 11 are grinding and polishing the hub body 001, only the upper parts of the grinding disc 9 and the polishing disc 11 are in contact with the hub body 001, and the grinding disc 9 and the polishing disc 11 have large wear. Therefore, when it is necessary to move the grinding disc 9 and the polishing disc 11 to change the grinding and polishing position of the hub body 001, control the first electric actuator 6 to extend, so that the grinding disc 9 or the polishing disc 11 is separated from the hub body 001. At this time, control the second electric actuator 14 to extend, and synchronously drive the pin rod 15 to slide in the fixed ring 8. The pin rod 15 withdraws from the card slot of the inner lining ring 12. Then control the second motor 17 to start. The second motor 17 drives the driving wheel 18 to rotate through the pulley. The driving wheel 18 drives the inner lining ring 12 to rotate on the fixed ring 8, and synchronously drives the grinding disc 9 and the polishing disc 11 to rotate. Thus, the positions of the grinding disc 9 and the polishing disc 11 used for processing the hub body 001 are adjusted. Then control the second electric actuator 14 to contract, and synchronously make the pin rod 15 insert into the card slot of the inner lining ring 12, thereby fixing the inner lining ring 12. Then control the first electric actuator 6 to contract, so that the fixed ring 8 descends, and the grinding disc 9 or the polishing disc 11 is in contact with the hub body 001 for grinding or polishing the hub body 001, effectively avoiding excessive local wear caused by the processing of the grinding disc 9 or the polishing disc 11 and the hub body 001. Through the rotation of the grinding disc 9 and the polishing disc 11, the positions of the grinding disc 9 and the polishing disc 11 are adjusted, so that the grinding disc 9 and the polishing disc 11 are fully utilized, reducing the consumption of the grinding disc 9 or the polishing disc 11, as well as reducing the replacement frequency of the grinding disc 9 or the polishing disc 11, saving a lot of time and indirectly improving the processing efficiency.

[0034] During the processing of the hub body 001 by both the grinding disc 9 and the polishing disc 11, a large amount of heat will be generated. Therefore, the two second water pipes 20 are respectively connected to the water inlet pipe and the water outlet pipe of the external water circulation device. The external water circulation device injects cooling water into the upper cavity of the front hollow rotating shaft 7 through the second water pipes 20, as Figure 5As shown, then the cooling water enters each first water pipe 19. The first water pipe 19 is wound around the outside of the fixed ring 8. The heat generated by the grinding disc 9 and the polishing disc 11 during the processing of the hub body 001 is conducted to the first water pipe 19 through the inner lining ring 12 and the fixed ring 8 in sequence. The cooling water exchanges heat with the fixed ring 8 through the first water pipe 19, thereby cooling the fixed ring 8. The fixed ring 8 then cools the grinding disc 9 and the polishing disc 11 through the inner lining ring 12. Then, the lower pipe orifice of the first water pipe 19 conducts the water after heat exchange into the lower cavity of the front hollow rotating shaft 7, and then returns to the external water circulation device for cooling through the second water pipe 20 below, thereby cooling the grinding disc 9 and the polishing disc 11, effectively avoiding the local high temperature generated during the processing of the grinding disc 9 and the polishing disc 11, which causes the abrasion of the grinding disc 9 and the polishing disc 11 to intensify, reduces the service life of the grinding disc 9 and the polishing disc 11, and increases the production cost.

[0035] The second embodiment Based on the first embodiment, according to Figure 1 、 Figure 6 and Figure 7 As shown, it further includes a first conduit 21, a dust-removing cylinder 22, a second conduit 23 and a third conduit 24; a wedge-shaped groove is provided in the machine tool body 1, and the bottom of the groove communicates with a plurality of equally spaced first conduits 21; a dust-removing cylinder 22 is provided below the machine tool body 1; the dust-removing cylinder 22 communicates with all the first conduits 21; the upper part of the dust-removing cylinder 22 communicates with the second conduit 23; the lower part of the dust-removing cylinder 22 communicates with the third conduit 24; the position of the lower pipe orifice of the first conduit 21 is higher than the position of the third conduit 24, and the position of the lower pipe orifice of the first conduit 21 is lower than the position of the second conduit 23.

[0036] The intelligent processing method for an integrated aluminum alloy hub, which is applicable to the intelligent processing device for an integrated aluminum alloy hub, includes the following steps: 1. First, fix the hub body 001 on the machine tool body 1 and set the processing program through the touch screen; 2. Control the fixed ring 8 to move to the position of the hub body 001, and process the hub body 001 through the grinding disc 9 or the polishing disc 11 in sequence, and perform continuous processing in the same device to reduce the investment in additional equipment costs; 3. Control the rotation of the inner lining ring 12, and then adjust the positions of the grinding disc 9 and the polishing disc 11, so that the grinding disc 9 and the polishing disc 11 are fully utilized and the frequency of replacing the grinding disc 9 and the polishing disc 11 is reduced; 4. Preset a first water pipe 19 for heat dissipation in the fixed ring 8, and dissipate heat from the grinding disc 9 and the polishing disc 11 through heat exchange to avoid local high temperature generated during processing and damage the grinding disc 9 and the polishing disc 11; V. By pumping the gas in the machine tool body 1 into water, the aluminum powder generated during processing enters the water and settles, avoiding dust flying and realizing the recovery of aluminum powder.

[0037] The working steps of this embodiment are as follows: On the basis of the processing in the above embodiment, considering that a large amount of aluminum dust will be raised during the processing of the hub body 001, and a large amount of heat will also be generated during the processing. In this way, two of the three elements for dust explosion are satisfied. If there are sparks generated during the processing, it is easy to have the risk of dust explosion. Therefore, before starting the processing of the hub body 001, first pour cooling water into the dust settling cylinder 22 through the third conduit 24, and make the liquid level of the cooling water higher than the lower end pipe orifice of the first conduit 21 and lower than the pipe orifice of the second conduit 23. Connect the second conduit 23 to an external air pump. At this time, start the processing process, and the external air pump starts to pump air through the second conduit 23. The upper space of the dust settling cylinder 22 is in negative pressure. The dust settling cylinder 22 is connected to the machine tool body 1 through the first conduit 21. Therefore, the air in the machine tool body 1 enters the dust settling cylinder 22 through the first conduit 21. At the same time, the aluminum dust generated in the machine tool body 1 due to processing also enters the dust settling cylinder 22 together with the air. Since the air will contact the cooling water in the dust settling cylinder 22 after entering, the aluminum powder in the air is dissolved into the cooling water, and the cooling water also cools the air and the aluminum powder. And the air reaches the upper part of the dust settling cylinder 22 in the form of bubbles and is then pumped out by the external air pump through the second conduit 23. When the aluminum powder in the dust settling cylinder 22 needs to be exported later, only need to control and start the external pump. Bubbles will overflow from the first conduit 21 into the dust settling cylinder 22, thereby raising the aluminum powder settled in the dust settling cylinder 22 in the water. Then open the control valve of the third conduit 24, and the cooling water with aluminum powder can be exported, thus realizing the recovery of aluminum powder. Pumping air into the cooling water inhibits the raising of aluminum powder and reduces the risk of dust explosion.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
