[0021] Specifically, in this embodiment, a bottom plate 1 is included, a bottom shell 7 is fixed to the top outer wall of the bottom plate 1, a support plate 2 is arranged on the top of the bottom shell 7, two screw sleeves 3 are movably inserted inside the support plate 2, and the two screw sleeves 3 can move vertically inside the support plate 2, a top plate 4 is fixed to the top of the two screw sleeves 3, a conical hole 5 is opened on the bottom outer wall of the top plate 4, and two screw rods 10 are connected to the top outer wall of the bottom shell 7 through a bearing, and the top end of the screw rod 10 is connected to the screw sleeve 3 through a thread, and the screw sleeve 3 is driven to move when the screw 10 rotates. The bottom end of the screw rod 10 extends to the inside of the bottom shell 7 where a driven gear 11 is fixed, and a motor 13 is fixed to the top outer wall of the bottom shell 7. The output shaft of the motor 13 extends to the inside of the bottom shell 7 where a driving gear 12 is fixed. The motor 13 drives the driving gear 12 to rotate, and the driving gear 12 is meshed with the driven gear 11. The driving gear 12 drives the two driven gears 11 to rotate synchronously, so that the two screw rods 10 can also keep in sync when rotating, preventing the two sides from being out of sync when the top plate 4 moves up and down.

[0022] The utility model provides a device for processing and fixing an automobile wheel hub axle tube, which drives two threaded sleeves 3 to move respectively through the rotation of two screw rods 10, so that the axle tube body 6 can be conveniently pressed and fixed on the support plate 2 when the top plate 4 is pressed down, and the fixing position of the axle tube body 6 is unique, so that a batch of wheel hub axle tube bodies 6 do not need to be aligned each time when processing the keyway, thereby making the processing of the wheel hub axle tube more efficient.

[0023] In another embodiment provided by the utility model, a shaft tube body 6 is provided on the top outer wall of the support plate 2. The outer wall of the shaft tube body 6 is tapered. The shaft tube body 6 is located inside the tapered hole 5. The tapered hole 5 is adapted to the shaft tube body 6, so that when the support plate 2 is pressed down, the shaft tube body 6 can be pressed in a fixed position through the tapered hole 5, so that when batches of shaft tube bodies 6 are fixed in sequence, their fixed positions are the same. Since the top end of the shaft tube body 6 is circular, when the keyway is milled on the side wall of its top end, it is only necessary to align the tool for the first fixed shaft tube body 6, and the keyway can be directly milled for the subsequent shaft tube bodies 6 of the same specification without aligning the tool when they are fixed.

[0024] In another embodiment provided by the utility model, a pillar 8 is fixed between the support plate 2 and the base plate 1, a countersunk hole 9 is opened on the top outer wall of the base plate 1, and the countersunk hole 9 is used to conveniently fix the base plate 1 on the machine tool using bolts, and a retaining ring 14 is fixed to the bottom outer wall of the screw sleeve 3, and the retaining ring 14 is used to prevent the screw sleeve 3 from being separated from the support plate 2.

The guide cylinder 17 is used to make the screw sleeve 3 more stable when it moves up and down, and a graphite block 18 is embedded in the inner wall of the guide cylinder 17, and the graphite block 18 is used to make the screw sleeve 3 have a lubricating effect when it moves up and down.

[0025] In another embodiment provided by the utility model, a filling pipe 15 is welded to the top outer wall of the bottom shell 7, and a sealing cover 16 is connected to the top of the filling pipe 15 by a thread. Lubricating oil can be added to the bottom of the bottom shell 7 through the provided filling pipe 15, so that the meshing transmission between the driving gear 12 and the driven gear 11 is lubricated; an observation window 19 is provided on one side outer wall of the bottom shell 7, and a drain valve 20 is connected to one side outer wall of the bottom shell 7. The color of the lubricating oil can be penetrated through the observation window 19. When the lubricating oil needs to be replaced, the lubricating oil can be conveniently discharged by opening the drain valve 20.

[0026] Working principle: when the shaft tube body 6 needs to be fixed, the motor 13 drives the driving gear 12 to rotate, so that the driving gear 12 drives the driven gear 11 to rotate, and the two driven gears 11 respectively drive the two screws 10 to rotate synchronously, so that the screw sleeve 3 drives the top plate 4 to rise; then the shaft tube body 6 is placed on the support plate 2, and the shaft tube body 6 is located directly below the tapered hole 5 of the top plate 4.
