[0025] A screw rod 8 is provided in the accommodating chamber 2, one end of the screw rod 8 slides through the end of the tooling body 1 away from the opening, and the other end of the screw rod 8 is detachably connected to the static pressure guide rail 3. The end of the tooling body 1 away from the opening is rotatably connected to a rotating block 5, and a threaded hole is provided on the rotating block 5. The screw rod 8 passes through one end of the tooling body 1 and is threadedly connected to the threaded hole.
[0026] Specifically, one end of the opening of the tool body 1 is connected to the machine tool 4 through the alignment sleeve 14, and a first through hole and a second through hole are sequentially provided in the axial direction of the alignment sleeve 14, the first through hole and the second through hole are communicated, the inner diameter of the second through hole is the same as the radial size of the opening of the tool body 1, the inner diameter of the first through hole is larger than the outer diameter of the tool body 1, a plurality of first screw holes 16 are provided in the first through hole along the circumference of the second through hole, the first screw holes 16 pass through the alignment sleeve 14 axially, and the machine tool 4 is provided with mounting screw holes corresponding in number and position to the first screw holes 16 on the side close to the tool body 1, and the alignment sleeve 14 and the machine tool 4 are connected by bolts, the first screw holes 16 and the mounting screw holes through the threaded fit;
[0027] One end of the opening of the tooling body 1 is arranged in the first through hole, and a main body pressure cover 13 is fixed to the outer wall of the open end of the tooling body 1. A plurality of mounting holes are provided on the main body pressure cover 13 along the circumferential direction, and the alignment sleeve 14 is provided with a plurality of second screw holes on the outer wall of one end of the first through hole. The number of the second screw holes corresponds to the position of the mounting holes, and the main body pressure cover 13 and the alignment sleeve 14 are connected with the threads of the mounting holes and the second screw holes by bolts.
[0028] Specifically, an alignment ring 15 is provided between the inner wall of the first through hole and the outer wall of the tool body 1 , and the alignment ring 15 guides the alignment sleeve 14 to enhance the fixing effect of the alignment sleeve 14 on the tool body 1 .
[0029] Specifically, the screw rod 8 is detachably connected to the static pressure guide rail 3 through a disassembly pull block, and the disassembly pull block includes a first disassembly pull block 9 and a second disassembly pull block 10. The first disassembly pull block 9 is provided with a cylindrical protrusion 11 at one end, and the outer wall of the cylindrical protrusion 11 is provided with an external thread.

After the hydrostatic guide rail 3 is completely pulled out of the machine tool 4, remove the tool body 1 from the machine tool 4, and then remove the hydrostatic guide rail 3 from the tool body 1 to repair the hydrostatic guide rail 3. Specifically, the hydrostatic guide rail 3 can be disassembled from the tool body 1 by rotating the rotating block 5 in the opposite direction to push the hydrostatic guide rail 3 out of the tool body 1, and then rotating the second disassembly pull block 10 to separate the second disassembly pull block 10 from the first disassembly pull block 9, and then using a screwdriver to rotate the screw 17 to remove the screw 17 to complete the disassembly of the hydrostatic guide rail 3.
