The first 90-degree folding mechanism and the second 90-degree folding mechanism can realize two-step processing in one processing station.

[0004] In the prior art, since the first processing mechanism is installed on the rack, and part of the first processing mechanism is located above the rack, when the hub to be processed is placed from top to bottom on the rack, the hub is prone to collide with the first processing mechanism, thereby reducing the quality of the processed hub. Moreover, when the hub is placed into the rack from the side of the rack, since the clamping mechanism is fixedly installed on the rack, the hub is prone to collide with the clamping mechanism, thereby reducing the quality of the processed hub.

[0018] Compared with the prior art, the automobile hub processing device has the beneficial effects that:

[0019] 1. The first lifting mechanism can drive the first lifting plate and the inner support mechanism to move up and down by installing the inner support mechanism on the first lifting plate and connecting the first lifting mechanism with the first lifting plate, so that the inner support mechanism can pass through the accommodation hole to ensure that the inner support mechanism can be fitted with the inner wall of the hub body, and then the hub body is fixed on the rotating plate to ensure that the rotating plate drives the hub body to rotate, so as to facilitate turning and drilling processing of the hub body. Since the feeding mechanism is located on one side of the first mounting frame, the hub body can be placed on the rotating plate from the side of the rotating plate, so as to avoid collision between the hub body and the drilling mechanism, thereby improving the quality of processing the hub body. Since the first lifting mechanism can drive the first lifting plate and the inner support mechanism to move up and down, when the hub body is not placed on the rotating plate, the inner support mechanism can be hidden below the rotating plate, so as to avoid collision between the hub body and the inner support mechanism when the hub body is transported to the rotating plate, thereby improving the quality of processing the hub body.

[0020] 2. When preparing to adjust the height of the first lifting plate, start the first motor to drive the rotating shaft to rotate, so that the rotating shaft drives the first lead screw to rotate through the two second synchronous wheels and the second synchronous belt; since the two first synchronous wheels are respectively sleeved on the outer sides of the two first lead screws, and the first synchronous belt is sleeved on the outer sides of the two first synchronous wheels, when one first lead screw rotates, the first lead screw drives the other first lead screw to rotate through the two first synchronous wheels and the first synchronous belt, so that the two first lead screws rotate synchronously, and then the two first lead screws drive the first lifting plate to move up and down in cooperation.

[0021] 3. When preparing to fix the hub body on the rotating plate, start the double-head motor to drive the two second lead screws to rotate synchronously; since the spiral directions of the second external threads on the outer walls of the two second lead screws are opposite, the two second lead screws respectively drive the two first inner support plates to move in opposite directions, so that the two first inner support plates are fitted with the inner wall of the hub body; at the same time, the second lead screw drives the third lead screw to rotate through the first bevel gear and the second bevel gear, so that the third lead screw drives the second inner support plate to move, and then the second inner support plate is fitted with the inner wall of the hub body to fix the hub body on the rotating plate.

[0022] 4. When the hub body is drilled, the first cylinder is started to drive the positioning frame and the positioning plate to move upwards, so that the positioning plate is embedded in the first positioning groove; then, the drilling mechanism and the second lifting mechanism are started to drill the hub body; after the drilling of the hub body is completed, the second cylinder is started to drive the connecting plate to move away from the connecting frame through the limiting clamping plate, so that the positioning plate is separated from the first positioning groove, and the spring is in a compressed state; at the same time, the rotating plate is rotated to drive the connecting frame and the hub body to rotate; then, the second cylinder drives the limiting clamping plate to move towards the connecting frame, at this time, the limiting clamping plate is separated from the connecting plate, and the spring is reset and drives the positioning plate to move towards the connecting frame until the positioning plate is attached to the connecting frame; when the positioning plate is opposite to the first positioning groove, the positioning plate is embedded in the first positioning groove, so that the connecting frame is positioned to avoid the rotating plate from continuing to rotate, thereby improving the drilling precision of the drilling mechanism on the hub body.

[0023] 5. The fourth threaded hole is arranged through the first translation table, and the fourth lead screw passes through the fourth threaded hole to achieve threaded connection between the fourth lead screw and the first translation table, so that the fourth lead screw is rotated to drive the first translation table to rotate, thereby adjusting the distance between the first translation table and the rotating plate.

[0024] 6. The fifth threaded hole is arranged in the second lifting plate, and the fifth lead screw passes through the fifth threaded hole to achieve threaded connection between the fifth lead screw and the second lifting plate, so that the fifth lead screw is rotated to drive the second lifting plate to move up and down, thereby adjusting the height of the second lifting plate.

[0025] 7. The drill bit is installed in the second accommodating groove of the drill rod to enable the drill rod to drive the drill bit to rotate, thereby enabling the drill bit to drill the hub body; the third motor is fixed on the second lifting plate to enable the second lifting plate to support the third motor, thereby enabling the second lifting plate to drive the third motor to move up and down; the third bevel gear is sleeved on the outside of the third output shaft of the third motor, the fourth bevel gear is sleeved on the outside of the drill rod, and the fourth bevel gear is engaged with the third bevel gear, so that when the third motor drives the third bevel gear to rotate, the third bevel gear drives the drill rod to rotate through the fourth bevel gear, thereby providing power for the rotation of the drill rod and the drill bit.

[0026] 8. The sixth threaded hole is arranged through the second translation table, and the sixth lead screw passes through the sixth threaded hole to achieve threaded connection between the sixth lead screw and the second translation table, so that the sixth lead screw is rotated to drive the second translation table to move, thereby adjusting the distance between the second translation table and the rotating plate.

[0027] 9. By connecting one end of the seventh lead screw to the fourth output shaft of the fourth motor and rotatably connecting the other end of the seventh lead screw to the second translation table, the fourth motor and the second translation table cooperate to support the seventh lead screw, so that the fourth motor can drive the seventh lead screw to rotate; by setting the seventh threaded hole in the third lifting plate and passing the seventh lead screw through the seventh threaded hole, the seventh lead screw is threadedly connected to the third lifting plate, so that the seventh lead screw is rotated, so that the seventh lead screw drives the third lifting plate to move up and down to adjust the height of the third lifting plate.

[0028] 10. First, place the hub body on multiple first transmission rollers; then, start the sixth motor, so that the sixth motor drives the ninth screw to rotate, so that the ninth screw drives the discharge plate and the positioning seat to move, and then the positioning seat is located above the rotating plate; then, start the fifth motor, so that the fifth motor drives the eighth screw to rotate, so that the eighth screw drives the feed plate and the push plate to move, and then the push plate pushes the hub body to move on the multiple first transmission rollers until the hub body moves to the rotating plate and the hub body is embedded in the second positioning groove to position the hub body; wait until the inner support mechanism is attached to the inner wall of the hub body After closing, start the sixth motor, so that the sixth motor drives the ninth screw to rotate, so that the ninth screw drives the discharge plate and the positioning seat to move away from the hub body; after completing the processing of the hub body, start the fifth motor, so that the fifth motor drives the eighth screw to rotate, so that the eighth screw drives the feed plate and the push plate to move, and then the push plate pushes the hub body to move onto the second transmission roller; then, rotate the second transmission roller, so that the second transmission roller drives the hub body to move, so that the hub body is away from the rotating plate, so as to facilitate the transportation or lifting of the hub body, thereby completing the unloading of the hub body.
