[0028] Reference Figure 1 , Figure 4 , Figure 6 and Figure 7 In order to fix the half-shaft connection flange when drilling, a blind hole 22 is horizontally opened in the center of the guide block 5, and the inner wall of the blind hole 22 axially fixes the spring 21, and the end of the spring 21 is fixedly connected to the guide rod 20, and the guide rod 20 is axially slidably connected in the blind hole 22.

The annular groove 10 is provided on the round block 6 to prevent the drill rod from moving too much when the drilling rig 14 is drilling a hole in the flange, which may cause the drill rod to collide with the round block 6.

[0030] Working principle: When in use, place the direction of the first slope 3 of multiple connecting shafts to be processed on the top surface of the first frame 1. When placing, place the flange end on the half-axis toward the direction of the drilling rig 14. Under the action of the first slope 3, multiple half-axes slide into the guide groove 4 on the round block 6, and then drive the motor 9 to drive the round block 6 to rotate 90 degrees counterclockwise, so that the half-axle in the guide groove 4 rotates to the top, and at the same time, the second half-axle will automatically slide into another guide groove 4 of the round block 6 to wait for processing. The servo motor 16 drives the screw 18 to rotate, and the screw 18 drives the guide plate 12 to move in the through groove 11 toward the flange through the threaded hole 15.

The spring 21 is compressed, and then The drilling machines 14 are started at the same time to drill holes in the flange. When the flange is opened, the servo motor 16 drives the guide plate 12 to retreat, and the electric push rod 13 drives the guide block 5 to retreat synchronously with the guide plate 12, so that the drilling machine 14 is separated from the flange with holes, and the spring 21 in the compressed state is reset until the oak block 19 is separated from the flange, and then the driving motor 9 is started again to drive the round block 6 to rotate 90 degrees counterclockwise, so that the processed half-shaft rotates to the direction of the second slope 7. The processed half-shaft rolls off the first frame 1 under the action of the second slope 7, and the second half-shaft to be processed will rotate to the direction of the drilling machine 14. At the same time, the third half-shaft to be processed will slide into another guide groove 4 through the first slope 3 to wait for processing. The operation is repeated in this way, so that the processing of multiple holes on the half-shaft flange can be completed at one time, and the automatic loading and unloading of the half-shaft during processing is also realized.
