As a specific implementation manner, the hydraulic chuck tool of the present embodiment may be preferably configured as the following structure:

the hydraulic chuck tool comprises three fan-shaped blocks and three hydraulic soft claws, wherein the three fan-shaped blocks are a fan-shaped block I3, a fan-shaped block II 22 and a fan-shaped block III 5 respectively, and the fan-shaped block I3, the fan-shaped block II 22 and the fan-shaped block III 5 are all fan-shaped blocks with arc angles of 120 degrees so as to be spliced into a circular axial positioning surface 10; the three hydraulic soft claws are respectively a first hydraulic soft claw 2, a second hydraulic soft claw 23 and a third hydraulic soft claw 24, and the three hydraulic soft claws are distributed at intervals along the circumferential direction of the circular end surface of the hydraulic chuck 1.

When in welding, a gap is ensured between any two adjacent fan-shaped blocks, allowance is reserved for the clamping and the loosening of the hydraulic soft claw, and the three fan-shaped blocks are ensured not to interfere with each other so as to clamp a workpiece. According to the position of the bolt hole on the hydraulic soft claw III 24, a bolt hole I6 and a bolt hole II 7 are drilled at the corresponding position of the sector III 5, and the hydraulic soft claw III 24 is fixed on the hydraulic chuck 1 through the bolt hole I6 and the bolt hole II 7 by bolts. Firstly, roughly turning a first sector block 3, a second sector block 22 and a third sector block 5 on the hydraulic chuck 1, then detaching the hydraulic chuck 1, placing the hydraulic chuck in a machining center for milling a magnet mounting hole 8, and then installing the tool on a numerical control lathe or other machining equipment again. The size of the radial clamping surface 9 is designed to be R115 according to the major diameter 21 of the to-be-processed fan-shaped annular cushion block 25 (R115 represents that the outer circle radius of the to-be-processed fan-shaped annular cushion block 25 is 115), the diameter of the radial supporting position 11 is designed according to the size of the inner hole of the supporting piece 17, namely the size of the inner diameter 18 of the supporting ring, and a gap is reserved so as to facilitate the free entering and exiting of the supporting piece 17. The axial positioning surface 10 is used for axially positioning the fan ring block 25 to be machined. Thus, the radial clamping surface 9, the axial positioning surface 10 and the radial supporting position 11 are formed in one step in the same process, so that the positioning accuracy of the tool is ensured.

and when a foot switch is stepped or other modes of switches are started, the hydraulic chuck 1 is released, and three segments, namely the first segment 3, the second segment 22 and the third segment 5 are opened. The supporting piece 17 is pushed to the bottom of the tool along the radial supporting position 11, then a first cushion block 12, a second cushion block 13, a third cushion block 14, a fourth cushion block 15 and a fifth cushion block 16 are respectively placed in the tool, and the five cushion blocks are tightly attached to the axial positioning surface 10 through magnetic force. When the foot switch is stepped again or the switch of other modes is started, the hydraulic chuck 1 clamps the workpiece, and the start button of the machining equipment, such as a machine tool, is pressed to start machining the workpiece. After one surface is processed, the hydraulic chuck 1 can be loosened, the direction of the cushion block is turned, and then the reverse surface can be processed conveniently and quickly.
