[0054] Embodiment 1: Figure 1-6 As shown, a hollow shaft gear shaping processing device comprises:

[0055] A workbench 1 is provided with a guide rail and a placement groove; a clamping claw 2 is provided on the guide rail, and the clamping claw 2 is used to clamp a hollow shaft 5; and a base 4 is provided in the placement groove.

[0056] The centering and tightening mechanism 3 is arranged on the base 4, and the centering and tightening mechanism 3 includes: a shell 31, the shell 31 is arranged on the base 4, and the shell 31 is provided with a accommodating part one and an accommodating part two; a driving rod 32, the rod is arranged in the shell 31, and the driving rod 32 passes through the shell 31 up and down; a first base 33, the first base 33 is arranged in the accommodating part one, and the first base 33 is used to correct the left and right positions of the hollow shaft 5; a second base 34, the second base 34 is arranged in the accommodating part two, the second base 34 is arranged below the first base 33, and the second base 34 is used to correct the front and rear positions of the hollow shaft 5.

[0057] The guide rail is set with T-slot.

[0058] The first base 33 includes: a rotating driving member 333, which is sleeved on the outer side of the driving rod 32, and the rotating driving member 333 and the driving rod 32 cooperate with each other; a driven push rod 332, which is provided with two driven push rods 332, and the driven push rods 332 and the outer side of the rotating driving member 333 are fitted together; an arcuate top plate 331, which is provided at the outer end of the driven push rod 332, and is used to support the inner wall of the hollow shaft 5 for centering and tightening.

[0059] The second base 34 includes: a second rotating driving member 343, which is sleeved on the outer side of the driving rod 32, and the second rotating driving member 343 and the driving rod 32 cooperate with each other; a second driven push rod 342, which is provided with two driven push rods 342, and the second driven push rod 342 and the outer side of the second rotating driving member 343 are fitted together; a second arc-shaped top plate 341, which is provided at the outer end of the second driven push rod 342, and the second arc-shaped top plate 341 is used to support the inner wall of the hollow shaft 5 for centering and tightening.

[0062] The outer ends of the arc top plate 1 331 and the arc top plate 2 341 are made of elastic material. The outer ends of the arc top plate 1 331 and the arc top plate 2 341 made of elastic material can increase the contact area with the inner wall of the hollow shaft 5 and increase the clamping force on the inner wall of the hollow shaft 5, so that the centering of the hollow shaft 5 is more accurate and the clamping is more stable, further avoiding the deviation of the centering clamping of the hollow shaft 5, further solving the problem of deviation of the centering clamping during the hollow shaft gear shaping process, and making the centering clamping during the hollow shaft gear shaping process less likely to deviate.

[0063] Embodiment 2: Figure 7-8As shown, based on the first embodiment, this embodiment further improves the housing 31:

[0068] The compression spring 63 is sleeved on the outer side of the limiting guide column 64 , and the compression spring 63 is arranged between the guide rod 62 and the placement groove.

[0069] By means of the auxiliary guide mechanism 6 provided on the shell 31, during the placement of the hollow shaft 5, the guide block 61 contacts the inner wall of the hollow shaft 5, and is guided by the inclined surface of the guide block 61, and the movement of the guide rod 62 is controlled to guide the hollow shaft 5 to a position biased toward the center, and the hollow shaft 5 is roughly centered in advance, and the first base 33 and the second base 34 are used to accurately center the hollow shaft 5, so that the centering is more accurate, and the deviation of the centering clamping of the hollow shaft 5 is avoided, which further solves the problem of deviation of the centering clamping during the hollow shaft gear shaping process, and can make the centering clamping during the hollow shaft gear shaping process less likely to deviate.
