[0024] As Figures 1 to 8 shown, an adjustable reamer includes a reamer 3 and also includes a tool shank 103. The tool shank 103 is a columnar structure, and a limiting mechanism is arranged in the axial direction of the tool shank 103. The limiting mechanism cooperates with an engaging mechanism arranged on the tool shank 103 to adjust the position of the reamer 3; a fluid part for cooling the reamer 3 is rotatably arranged on the tool shank 103. The fluid part includes a fluid housing 202 and a conduit 201. The fluid housing 202 is rotatably matched with the tool shank 103, and the conduit 201 is connected to the fluid housing 202. The conduit 201 communicates with the internal chamber of the fluid housing 202.

[0025] As Figure 3 , Figure 6 , Figure 7 shown, the limiting mechanism includes a first limiting nut 101 and a second limiting nut 102. Arc-shaped grooves for restricting the radial position of the reamer 3 are arranged on the planes of the first limiting nut 101 and the second limiting nut 102 close to the reamer 3.

[0026] As Figures 1 to 8 shown, the engaging mechanism includes a first thread section 105 and a second thread section 107 arranged on the outer surface of the tool shank 103. A fixing column 106 is arranged between the first thread section 105 and the second thread section 107. A through hole for fluid to pass through is arranged on the fixing column 106, and this through hole communicates with the hollow structure inside the tool shank 103; chutes for cooperating with the reamer 3 are arranged on the first thread section 105, the fixing column 106, and the second thread section 107; the first limiting nut 101 meshes with the first thread section 105, and the second limiting nut 102 meshes with the second thread section 107; the hollow structure inside the tool shank 103 communicates with the internal chamber of the fluid housing 202 through a fluid hole 104; a convex platform for installation is arranged at one end of the tool shank 103, and a tapered head is arranged at the other end of the tool shank 103; a through hole for fluid to pass through is arranged on the fixing column 106; the reamers 3 are distributed in a circular array around the rotation center of the tool shank 103, and the outer diameter of the reamer 3 is larger than the outer diameters of the tool shank 103, the first limiting nut 101, and the second limiting nut 102.

[0027] As Figures 1 to 8As shown in the figure, the working principle of a fine-tuning reamer disclosed by the utility model is as follows: The rectangular protrusion on the tool shank 103 of the device is installed on the processing equipment. When adjusting the position of the reamer 3, the operator manually turns the first limit nut 101 and the second limit nut 102, so that the first limit nut 101 and the second limit nut 102 move in one direction, and then the position of the reamer 3 sliding on the first thread section 105, the fixed column 106 and the second thread section 107 is changed to meet the requirements; after the position of the reamer 3 is adjusted, the operator manually rotates the first limit nut 101 and the second limit nut 102, so that the position of the reamer 3 is fixed between the first limit nut 101 and the second limit nut 102; at this time, both ends of the reamer 3 in contact with the first limit nut 101 and the second limit nut 102 are in the arc-shaped grooves provided on the first limit nut 101 and the second limit nut 102, preventing the centrifugal force generated when the device rotates from throwing it out.

[0028] During cooling, the operator installs one end of the conduit 201 on the coolant delivery equipment; the coolant delivery equipment transports the coolant through the conduit 201 into the fluid housing 202, and through the holes on the fluid housing 202 and the fluid hole 104 into the tool shank 103. Finally, the coolant sprays out through the through holes on the fixed column 106 to the position where the processed workpiece contacts the reamer 3 for cooling and lubrication, and at the same time flushes out the debris generated during the processing to prevent the debris from affecting the processing.

[0029] During cooling, the operator installs one end of the conduit 201 on the cooling water delivery equipment; the cooling water delivery equipment transports the cooling water through the conduit 201 into the fluid housing 202, and through the holes on the fluid housing 202 and the fluid hole 104 into the tool shank 103. Finally, the cooling water sprays out through the through holes on the fixed column 106 to the position where the processed workpiece contacts the reamer 3 for cooling and lubrication, and at the same time flushes out the debris generated during the processing to prevent the debris from affecting the processing.

[0030] During cooling, the operator installs one end of the conduit 201 on the air pressure delivery equipment; the air pressure delivery equipment transports the pressurized air through the conduit 201 into the fluid housing 202, and through the holes on the fluid housing 202 and the fluid hole 104 into the tool shank 103. Finally, the pressurized air sprays out through the through holes on the fixed column 106 to the position where the processed workpiece contacts the reamer 3 for cooling, and at the same time blows out the debris generated during the processing to prevent the debris from affecting the processing.
