An airbag assembly 6 is inserted into the bottom of the fixing ring 10. The airbag assembly 6 is in threaded connection with the limiting ring. The airbag assembly 6 and the movable ring 101 are connected and fixed through a plurality of fastening components. It should be noted that the length of the connecting rod is greater than half of the length of the first I-shaped movable block 71.

At the same time, a grinding ring body 51 is fixedly installed at the bottom of the grinding disc body 5 outside the limiting card slot 52.

[0037] Among them, the airbag assembly 6 includes a fixing ring seat. A limiting support rod 62 is installed in the middle of the bottom end of the fixing ring seat. An airbag body is fixedly installed outside the limiting support rod 62 at the bottom end of the fixing ring seat. The bottom of the limiting support rod 62 is fixedly connected with the bottom inside the airbag body.

[0038] At the same time, an external thread part is arranged above the outer wall of the fixing ring seat.

An internal thread part is arranged at the bottom inside the limiting ring at the external thread part. The internal thread part is in threaded connection with the external thread part. It should be noted that a plurality of waist-shaped installation holes are penetrated through the movable ring 101 at equal intervals. When the limiting ring is screwed with the fixing ring seat, the waist-shaped through holes of the movable ring 101 are aligned with the first installation holes of the installation ring 63.

[0039] Moreover, a support convex block 65 is installed at the top of the fixing ring seat. An auxiliary component 9 is arranged on the top of the support convex block 65. The auxiliary component 9 includes a micro air extraction and inflation dual-purpose pump body 91. The micro air extraction and inflation dual-purpose pump body 91 is installed on the top of the support convex block 65. The air outlet end and the air inlet end of the micro air extraction and inflation dual-purpose pump body 91 are both located on one side of the support convex block 65. The micro air extraction and inflation dual-purpose pump body 91 and the support convex block 65 are fixedly connected through an auxiliary support.

[0040] Meanwhile, pneumatic stop valves 92 are installed at both the air outlet end and the air inlet end of the micro air extraction and inflation dual-purpose pump body 91. One side of the pneumatic stop valve body 92 is connected with an auxiliary connecting pipe 93. The auxiliary connecting pipe 93 is in a Y shape. An auxiliary groove is formed on one side of the support bump 65 at the top of the fixed ring seat, and the cross-sectional area of the auxiliary groove is larger than that of the auxiliary connecting pipe 93. A pore 66 is formed in the fixed ring seat below the auxiliary groove and at the position of the auxiliary connecting pipe 93. The air outlet end and the air inlet end of the micro air extraction and inflation dual-purpose pump body 91 are fixedly connected with the corresponding pneumatic stop valve bodies 92 through a plurality of fastening components. The pneumatic stop valve body 92 and the auxiliary connecting pipe 93 are fixedly connected through a plurality of fastening components. The auxiliary connecting pipe 93 and the auxiliary groove are fixedly connected through a plurality of bolts. The fastening components include fastening bolts and fastening nuts, and the fastening bolts and the fastening nuts are in threaded connection. The fastening bolts and the fastening nuts are existing products already disclosed in the current market and do not belong to the main technical problems to be solved in the present invention. Therefore, they are not elaborated in the present invention.

[0041] Among them, the pneumatic stop valve body 92 is equipped with a pressure gauge, and the model of the pneumatic stop valve body 92 is NTPSV-633. The model of the micro air extraction and inflation dual-purpose pump body 91 is PCF5015N. The airbag is evacuated or inflated through the arrangement of the micro air extraction and inflation dual-purpose pump body 91. The specific structures and working principles of the micro air extraction and inflation dual-purpose pump body 91 and the pneumatic stop valve body 92 are existing products already disclosed in the current market and do not belong to the main technical problems to be solved in the present invention. Therefore, they are not described in the present invention anymore.

[0042] Moreover, a plurality of auxiliary bumps 64 are arranged at equal intervals in a circular shape on the outer part of the top of the fixed ring seat. A clamping groove is formed at the position of the auxiliary bump 64 at the bottom of the fixed ring 10. A clamping cavity is formed at the bottom inside the fixed ring 10, and the cross-sectional area of the clamping cavity is larger than the sum of the cross-sectional areas of the support bump 65 and the auxiliary groove. A ventilation hole is formed above the clamping cavity inside the fixed ring 10.

[0043] Meanwhile, a placement cavity is formed in the middle above the connection cavity inside the grinding disc body 5. A hydraulic rod assembly 8 is arranged in the placement cavity. The top extension end of the hydraulic rod assembly 8 is vertically downward connected with a limit insertion rod assembly 81. A limit cavity is formed above the connection cavity and below the placement cavity of the grinding disc body 5, and the cross-sectional area of the limit cavity is larger than that of the limit insertion rod assembly 81. It should be noted that the limit insertion rod assembly 81 is driven by the hydraulic rod assembly 8 to perform a linear motion in the vertical direction. The specific structure, connection method and working principle of the hydraulic rod assembly 8 are existing technologies already disclosed in the current market and do not belong to the main technical problems to be solved in the present invention. Therefore, they are not described in the present invention anymore.

[0044] Among them, the limit plug rod assembly 81 includes a fixed seat. In the middle of the bottom end of the fixed seat, a first plug rod body is provided. Around the bottom end of the fixed seat, second plug rod bodies are provided. Second limit slots are opened at the tops of the first I-shaped movable block 71 and the second I-shaped movable block 72 where they are located at the second plug rod bodies. And a jack is penetrated and opened at the top of the first I-shaped movable block 71 where it is located at the first plug rod body. A first limit slot is opened in the second I-shaped movable block 72 where it is located at the first plug rod body. And the three magnetic induction switch bodies 74 are all connected and controlled with the hydraulic rod assembly 8 through electric signals.

[0045] Among them, it should be noted that when all three T-shaped fixing blocks 73 are close to and in contact with the corresponding magnetic induction switch bodies 74, the magnetic induction switch bodies 74 control to open the hydraulic rod assembly 8. The top extension end of the hydraulic rod assembly 8 extends, driving its limit plug rod assembly 81 to be inserted into the corresponding first I-shaped movable block 71 and second I-shaped movable block 72, so as to limit the first I-shaped movable block 71 and the second I-shaped movable block 72, and ensure the stability when the airbag assembly 6 rotates. When one of the three T-shaped fixing blocks 73 is not close to and in contact with the corresponding magnetic induction switch body 74, the magnetic induction switch body 74 controls to close the hydraulic rod assembly 8. The top extension end of the hydraulic rod assembly 8 retracts, driving its limit plug rod assembly 81 to move away from the first I-shaped movable block 71 and the second I-shaped movable block 72 and be located in the limit cavity.

[0046] Moreover, a control cabinet is provided on one side of the deburring equipment body 1. The control cabinet is equipped with a display screen. The display screen is connected and controlled for transmission with the pressure gauge of the pneumatic stop valve body 92 through an electric signal. And the control cabinet is connected and controlled for transmission with the micro air extraction and inflation dual-purpose pump body 91, the driving motor 4, the vertical and horizontal driving unit 21, the horizontal and horizontal driving unit 22, and the vertical driving unit 23 through electric signals. At the same time, the display screen is connected and controlled for transmission with the hydraulic rod assembly 8 through an electric signal. The current on or off state of the hydraulic rod assembly 8 can be observed through the display screen.

[0047] In the present invention, under normal conditions, when all three T-shaped fixing blocks 73 are close to and in contact with the corresponding magnetic induction switch bodies 74, the magnetic induction switch bodies 74 control to open the hydraulic rod assembly 8. The top extension end of the hydraulic rod assembly 8 extends, driving its limit plug rod assembly 81 to be inserted into the corresponding first I-shaped movable block 71 and second I-shaped movable block 72, so as to limit the first I-shaped movable block 71 and the second I-shaped movable block 72, and ensure the stability when the airbag assembly 6 rotates.

[0048] Next, the vertical horizontal drive unit 21, the horizontal horizontal drive unit 22, and the vertical drive unit 23 are used to control the grinding assembly to perform vertical horizontal linear motion, horizontal horizontal linear motion, and vertical linear motion in sequence, so that the grinding assembly moves towards the hole of the aluminum alloy wheel hub. At the same time, the drive motor 4 is controlled to be turned on, and the drive motor 4 drives the grinding disc body 5 to rotate. While rotating, the airbag assembly 6 is driven to rotate. Among them, the inner wall of the hole of the aluminum alloy wheel hub is polished and deburred by the abrasive grinding sheet 61 of the airbag assembly 6, and at the same time, the aluminum alloy wheel hub is polished by the grinding ring body 51.

[0049] When it is necessary to polish the inclined inner wall of the aluminum alloy wheel hub, the micro air extraction and inflation dual-purpose pump body 91 is controlled to be turned on to extract the gas in the airbag body, and the range value of the pressure gauge is continuously monitored through the display screen to ensure the air pressure value in the airbag body. Then, the vertical horizontal drive unit 21, the horizontal horizontal drive unit 22, and the vertical drive unit 23 are used to control the grinding assembly to perform vertical horizontal linear motion, horizontal horizontal linear motion, and vertical linear motion in sequence, so that the airbag body and the abrasive grinding sheet 61 move along the inner wall of the hole of the aluminum alloy wheel hub to polish and deburr the inner wall of the hole of the aluminum alloy wheel hub. And because the micro air extraction and inflation dual-purpose pump body 91 releases a certain amount of gas in the airbag body, the gas content in the airbag body decreases, and its volume will shrink accordingly. This makes the airbag body easier to adapt to the shape and size of the inner wall of the hole of the aluminum alloy wheel hub. When the airbag body rotates, since the vertical horizontal drive unit 21, the horizontal horizontal drive unit 22, and the vertical drive unit 23 control one side of the airbag body to fit the inner wall of the hole of the aluminum alloy wheel hub in sequence, when the airbag body rotates, the outer side of the airbag body can fit the inner wall of the hole of the aluminum alloy wheel hub more tightly, reducing the existence of air gaps and clearances. And the limit support rod 62 ensures that the airbag body will not deviate during the rotation process.

[0050] When it is necessary to polish the surface of the aluminum alloy wheel hub, the vertical horizontal driving unit 21, the horizontal horizontal driving unit 22, and the vertical driving unit 23 are used to control the polishing assembly to perform vertical horizontal linear motion, horizontal horizontal linear motion, and vertical linear motion in sequence. While the polishing disc body 5 moves towards the surface of the aluminum alloy wheel hub, its polishing rod assembly is pressed against the inner wall of the aluminum alloy wheel hub, and its airbag assembly 6 rotates under the action of the corresponding first I-shaped movable block 71 or the second I-shaped movable block 72. During the rotation process, the magnetic induction switch body 74 in the first I-shaped movable block 71 or the second I-shaped movable block 72 moves away from its corresponding T-shaped fixed block 73. When one of the three T-shaped fixed blocks 73 does not approach and fit with the corresponding magnetic induction switch body 74, the magnetic induction switch body 74 controls the hydraulic rod assembly 8 to close, and the top extension end of the hydraulic rod assembly 8 retracts, driving its limit insertion rod assembly 81 away from the first I-shaped movable block 71 and the second I-shaped movable block 72 and located in the limit cavity, so that its limit insertion rod assembly 81 no longer limits the polishing rod assembly, ensuring that the polishing rod assembly can rotate smoothly. When the polishing disc body 5 moves towards the surface of the aluminum alloy wheel hub and away from the holes in the aluminum alloy wheel hub, the airbag body gradually moves into the limit slot 52, thus not interfering with the polishing ring body 51 to polish the surface of the wheel hub, and there is no need for frequent polishing tools, reducing the downtime and the number of operation interruptions, and improving the overall polishing efficiency.

[0051] At the same time, when continuing to polish the inner wall of the hole in the aluminum alloy wheel hub, the vertical horizontal driving unit 21, the horizontal horizontal driving unit 22, and the vertical driving unit 23 are used to control the polishing disc body 5 to move towards the hole until the polishing rod assembly rotates under its own weight until it moves away from the limit slot 52. Then, continue to move the polishing disc body 5 until the airbag assembly 6 fits against the inner wall of the wheel hub hole, and make its T-shaped fixed block 73 approach and fit with the corresponding magnetic induction switch body 74, and the magnetic induction switch body 74 controls the hydraulic rod assembly 8 to open. The top extension end of the hydraulic rod assembly 8 extends, driving its limit insertion rod assembly 81 to be inserted into the corresponding first I-shaped movable block 71 and the second I-shaped movable block 72 to limit the first I-shaped movable block 71 and the second I-shaped movable block 72, ensuring the stability of the airbag assembly 6 during rotation, and the opening state of the hydraulic rod assembly 8 can be observed through its display screen. When the hydraulic rod assembly 8 is in the open state, its limit insertion rod assembly 81 is inserted into the first I-shaped movable block 71 and the second I-shaped movable block 72, and then by controlling the driving motor 4 to open, the polishing disc body 5 and the airbag assembly 6 can be driven to rotate continuously.

[0052] In the present invention, through the cooperation of the grinding rod assembly and the grinding disc body 5, the surface and holes of the aluminum alloy wheel hub can be ground to remove burrs, and there is no need for frequent grinding tools, reducing the downtime and the number of operation interruptions, improving the overall grinding efficiency. At the same time, through the setting of the auxiliary assembly 9, the airbag body can be evacuated or inflated. When the gas in the airbag body is released, its volume will correspondingly shrink, enabling the outer side of the airbag body to fit more closely to the inner wall of the hole of the aluminum alloy wheel hub, reducing the existence of air gaps and clearances and ensuring its degree of fit.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
