The special machine for drilling and tightening pins for tool shaft according to claim 1, characterized in that: The tensioning pin hole-entering assembly comprises an oil cylinder (8), a tensioning pin material bin (7), a pushing cylinder (13), a clamping cylinder (14) and a feeding cylinder (15); a plurality of tensioning pins (3) are arranged in the tensioning pin material bin (7); the clamping cylinder (14) is arranged below the pushing cylinder (13); the pushing cylinder (13) pushes the tensioning pins (3) onto the clamping cylinder (14); the clamping cylinder (14) clamps the tensioning pins (3); the feeding cylinder (15) is connected to the clamping cylinder (14); the feeding cylinder (15) drives the clamping cylinder (14) to move to the position directly below the oil cylinder (8) and aligns the tensioning pins (3) with the oil cylinder (8) and the drilled through hole.

7. A special machine for drilling and tightening pins for tool bar shafts according to claim 6, characterized in that: The clamping cylinder (14) comprises two clamping parts that can be opened and closed, and the clamping parts are combined to form a circular cavity, and the tensioning pin (3) is clamped in the cavity formed by the clamping parts.

8. The special machine for drilling and tightening pins for tool bar shaft according to claim 3, characterized in that: It also includes an electric control box (4), which is electrically connected to the limit assembly, the tool bar shaft contour base (12), the drilling assembly, the tension pin hole entry assembly and the sliding assembly.

9. The tool bar shaft drilling and tensioning pin machine according to claim 2, characterized in that: Two pairs of arbor shaft bodies (1) and arbor shaft elbows (2) are symmetrically arranged on the arbor shaft contour base (12).

10. A drilling pressure method using the tool bar shaft equipped with a drilling pressure tension pin special machine according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Sleeve the tool arbor shaft elbow (2) onto the tool arbor shaft body (1), then place the tool arbor shaft elbow (2) and the tool arbor shaft body (1) on the tool arbor shaft contour base (12), and press the tool arbor shaft body (1) by rotating the tool arbor shaft body and pressing the cylinder (6); S2, operate the profiling base push-pull cylinder (5) to move the tool arbor shaft profiling base (12) to the position of the drill bit (11), then operate the tool arbor shaft elbow rotation clamping cylinder (10) to clamp the tool arbor shaft elbow (2), operate the drilling guide cylinder to move the drilling guide sleeve (9) to the drilling positioning position, then operate the servo power head (16) to start drilling, and the drill bit (11) passes through the drilling guide sleeve (9) until the tool arbor shaft elbow (2) is drilled through to form a through hole; S3, operate the tool bar shaft elbow rotating clamping cylinder (10) to release the clamping of the tool bar shaft elbow (2), operate the drilling guide cylinder to retract the drilling guide sleeve (9), operate the tool bar shaft profiling base (12) and the tension pin hole entry assembly to the corresponding position of the tension pin (3); S4, operate the push cylinder (13) to push the tension pin (3) in the tension pin material bin (7) out to the falling position, operate the clamping cylinder (14) to clamp the falling tension pin (3), and then the feeding cylinder (15) sends the tension pin (3) to the opening of the through hole drilled in S2, the oil cylinder (8) moves downward so that the end of the oil cylinder (8) presses against the tension pin (3) and clamps it into the hole, and then operates the clamping cylinder (14) to release it, and then starts the feeding cylinder (15) to retreat after release, and after the feeding cylinder (15) retreats, operates the oil cylinder (8) again to press the tension pin (3) into the hole until the root; S5. After the oil cylinder (8) is in place, it returns to the top, and the tool shaft processing is completed.
