Or the product is inconvenient to disassemble and assemble and sometimes needs to be disassembled together with the tool, so that the efficiency is low; the existing internal expanding tool is easy to lock with a workpiece. The centering device comprises a main mandrel and a clamping part, wherein the clamping part comprises two centering taper sleeves which are arranged in a mirror image mode and have inward conical surfaces, an expansion sleeve is arranged between the two centering taper sleeves, and two ends of the expansion sleeve are respectively sleeved outside the conical surfaces of the two centering taper sleeves.
Patent document 2(CN201720138746.8) discloses a large-diameter thin-walled cylinder turning tool, which is used in cooperation with a CA6140 lathe and comprises a power connecting seat, a reference seat, a circular die and a clamping pressure plate; the power connecting seat is located the leftmost end, and right fixed connection reference seat, the right-hand member of reference seat are equipped with the circle mould of fixed continuous with it, and the end of circle mould then is equipped with the clamping clamp plate. Patent document 3(cn201821595524.x) discloses a turning clamp for a large thin-wall hemispherical part, and relates to the technical field of turning equipment. The utility model discloses an including first turning anchor clamps and second turning anchor clamps, first turning anchor clamps include first base, the first anchor clamps body and first ball valve, are provided with the first anchor clamps body on the first base, and first anchor clamps body left end is provided with first ball valve, and the first anchor clamps body is the ascending semicircle structure of opening, and second turning anchor clamps include second base, the second anchor clamps body and second ball valve, are provided with the second anchor clamps body on the second base, and second anchor clamps body left end is provided with the second ball valve, and the second anchor clamps body is the decurrent semicircle structure of opening.
The structure disclosed in patent document 1 is used only for barrel outer circle machining, the structure is simple but the positioning accuracy is poor in patent document 2, and the structure is used for semi-spherical part machining in patent document 3. At present, a turning clamp and a machining process method for a thin-wall rotary part with a cavity are not available in the patent.

Drawings
FIG. 1 is a schematic view of a turning tool for thin-walled rotary parts with cavities according to the present invention;
in the figure: 1. thin-wall rotary parts with cavities; 2. vibration absorbing filler; 3. a base plate; 4. three claws; 5. a process chuck; 6. a lathe chuck.
Detailed Description
The technical scheme of the utility model is described in detail with the accompanying drawings and the embodiment as follows:
example 1:
as shown in figure 1, the turning tool for the thin-wall rotary part with the cavity comprises a lathe chuck 6, three jaws 4, a base plate 3 and a vibration absorption filler 2. The three-jaw chuck 4 is arranged on a lathe chuck 6 and used for clamping a process chuck 5 of the thin-wall rotary part 1 with the cavity, the cushion plate 3 is arranged on the three-jaw chuck 4, and the vibration absorption filler 2 is arranged in the cavity of the thin-wall rotary part 1 with the cavity and is integrally inserted into the centers of the cushion plate 3 and the three-jaw chuck 4.
