The two side walls of the fixture body (1) near one end are provided with first limiting holes (6) that penetrate the workpiece positioning hole (2). A first limiting pin (7) is inserted in the first limiting hole (6). The two side walls of the fixture body (1) near the other end are respectively provided with second limiting holes (8) facing each other. A second limiting pin (9) that abuts against the outer circumference of the round tube (3) is respectively provided in the two second limiting holes (8). A third limiting pin (10) is inserted in the first drill bit positioning hole (4) or the second drill bit positioning hole (5).

2. The high efficiency precision drilling jig for drilling of pipe blanks according to claim 1, characterized in that: A number of first drill bit positioning holes (4) and a number of second drill bit positioning holes (5) are arranged in a straight line along the axial direction of the workpiece positioning hole (2) on the top surface of the fixture body (1).

3. The high-efficiency precision drilling jig for drilling a pipe blank according to claim 1 or 2, characterized in that: The diameter of the first drill bit positioning hole (4) is smaller than the diameter of the second drill bit positioning hole (5).

4. The high-precision drilling jig for drilling a pipe blank according to claim 1, characterized in that: The third limiting pin (10) has a protruding ring (11) formed on its outer peripheral surface near its top end, which presses against the top surface of the fixture body (1) to limit the falling of the third limiting pin (10).

5. The high-precision drilling jig for drilling a pipe blank according to claim 1, characterized in that: The fixture body (1) has a plurality of first limiting holes (6) arranged at equal intervals along the axial direction of the workpiece positioning hole (2) on its side wall, and the first limiting holes (6) are divided into upper and lower rows.

6. The high-precision drilling jig for drilling a pipe blank according to claim 1, characterized in that: The top wall of the workpiece positioning hole (2) is provided with a guide step groove (12) along the axial direction of the workpiece positioning hole (2).

7. The high-precision drilling jig for drilling a pipe blank according to claim 1, characterized in that: The fixture body (1) has a discharge channel (13) that runs through both ends of it and is located below the workpiece positioning hole (2).

8. The high efficiency precision drilling jig for drilling a tube blank according to claim 7, wherein: The top of the discharge channel (13) is provided with a dropping channel (14) that communicates with the workpiece positioning hole (2). The dropping channel (14) is directly opposite the first drill bit positioning hole (4) and the second drill bit positioning hole (5) in the vertical direction.

9. The high-precision drilling jig for drilling a pipe blank according to claim 7 or 8, characterized in that: The bottom wall of the discharge channel (13) is inclined.

10. The high-precision drilling jig for drilling a pipe blank according to claim 1, characterized in that: The top of the fixture body (1) is provided with several bolt holes (15), and bolts are provided in the bolt holes (15).
