[0024] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0025] Please refer to the attached Figure 1-5 A clamping chuck with the functions of a gun drill and a reamer comprises a machine tool 1, a reamer 2, and a clamping chuck 3 installed on the machine tool 1.

[0026] For clamping, an inner chuck 4 is sleeved inside the clamping chuck 3, and an inner cone top plate 5 is connected to the end of the inner chuck 4 away from the machine tool 1, and clamping is completed by the inner cone top plate 5 abutting against the workpiece.

[0027] The inner chuck 4 is slidably arranged in the clamping chuck 3, and the upper and lower parts of the clamping chuck 3 are both provided with slots 6. The inner chuck 4 is provided with a chip removal opening 7 corresponding to the position of the slot 6. The lengths of the slot 6 and the chip removal opening 7 are both greater than the length of the reamer 2. An axial hole 8 is provided in the middle of the inner cone top plate 5, and the diameter of the axial hole 8 is greater than the diameter of the reamer 2. The reamer 2 is installed and used through the opening formed by the slot 6 and the chip removal opening 7.

[0028] During installation and use, the inner chuck 4 and the clamping chuck 3 are both hollow cylinders. The clamping chuck 3 is connected to the machine tool 1 through a flange. A push rod disk 9 is provided at one end of the inner chuck 4 close to the machine tool 1 through a flange connection. A rod groove 10 is convexly provided on the middle part of the push rod disk 9 close to the side of the machine tool 1. The push rod disk 9 is connected to the push rod inside the machine tool to control the small displacement to resist the workpiece.

[0029] A mounting groove 11 is concavely provided on the inner chuck 4 toward the push rod disk 9 , and the push rod disk 9 is installed in the mounting groove 11 through a flange. A conical ring 12 is provided around the axial center hole 8 on the inner cone top disk 5 toward the machine tool 1 .

[0030] Specifically

[0031] When the gun drill is drilling, the outer chamfer of the workpiece and the positioning of the workpiece are matched with the inner cone top plate, the hydraulic push rod of the machine tool pushes the inner chuck to position and clamp the workpiece, and the gun drill drills from right to left;

[0032] During the reaming process, the positioning and clamping of the workpiece is exactly the same as that during the gun drilling process. The reaming tool rod passes through the inner hole of the workpiece and enters the inner cavity of the clamping chuck. The reaming tool head is manually installed from the opening above the clamping chuck. The reaming process is carried out from left to right.

[0033] The iron filings generated by the hinge are discharged from the slot below the clamping chuck.

[0034] This clamping chuck is used on ordinary gun drilling machines to easily achieve rough processing (gun drilling) and fine processing (reaming).

[0035] Especially on the double-axis gun drilling machine, axis No. 1 is processed by gun drilling and axis No. 2 is processed by reaming, which greatly improves the use range of the machine tool and improves the processing efficiency.
