[0035] The floating disk 14 is sleeved onto the precision machining positioning disk 13, and the floating disk 14 and precision machining positioning disk 13 assembly is also provided with an elastic component 15.

[0036] Preferably, the fixing component 12 includes a sliding sleeve 121, a stretching sleeve 122, and a pull rod 123;

[0037] The center of the precision machining base 11 is provided with a positioning protrusion for inserting the precision machining positioning plate 13.

[0038] A sliding area is provided between the positioning protrusion and the precision machining positioning shaft 111. The sliding area is provided with a sliding sleeve 121. The pull rod 123 is provided at the tail end of the precision machining base 11, and the expansion sleeve 122 is provided at the other end. The sliding sleeve 121, the expansion sleeve 122 and the pull rod 123 are fixed by bolt connection.

[0039] Preferably, the precision machining positioning shaft 111 is provided with a limiting step 112, the expansion sleeve 122 is adjusted to the precision machining positioning shaft 111, and the limiting step 112 can limit the expansion sleeve 122.

[0040] Preferably, the end of the precision machining positioning shaft 111 has a tapered structure, and the inner side of the top end of the expansion sleeve 122 matches the end of the positioning post.

[0041] The outer side of the expansion sleeve 122 fits into the inner side of the connecting shaft; pulling the expansion sleeve 122 can achieve relative fixation between the connecting shaft and the precision machining positioning shaft 111.

[0042] Preferably, the end of the precision machining positioning plate 13 is used to abut against the connecting shaft; the first end of the floating plate 14 is sleeved onto the precision machining positioning plate 13, and the second end is used to support the connecting frame plate of the distributed planetary carrier.

[0045] The working principle is as follows: the distributed planetary carrier is sleeved onto the expansion sleeve 122. At this time, the expansion sleeve 122 is in the initial position, and the distributed planetary carrier and the expansion sleeve 122 make initial contact. At the same time, the end face of the floating disk 14 forms support for the distributed planetary carrier. During processing, the drive mechanism pulls the pull rod 123, and the expansion sleeve 122 moves down to fill the space between the distributed planetary carrier and the precision turning positioning shaft 111. As the expansion sleeve 122 moves down, the planetary carrier and the precision turning positioning shaft 111 become more and more fixed.

[0046] Then, the distributed planetary carrier is precision machined using precision machining equipment. During the machining process, the floating disk 14 will float to assist in positioning the planetary carrier, reducing vibration and deformation during machining.
