[0032] The working principle of a drilling machine with a fixed fixture provided by the present utility model is as follows: When the staff is performing the drilling work on mechanical parts, first adjust the gap between the clamping mechanisms 9 according to the width of the parts, remove the fixed plate 35, adjust the supports 31 on both sides to an appropriate gap, and then reinstall the fixed plate 35 to achieve the adjustment of the clamping width. Place the mechanical part to be drilled between the gaps of the pressing plate 91 and the auxiliary pressing plate 93. Rotate the first knob 92 to drive the second threaded rod 94 to rotate, thereby driving the pressing plate 91 to displace backward, reducing the gap between the pressing plate 91 and the auxiliary pressing plate 93, and achieving the clamping of mechanical parts of different sizes. Rotate the second knob 11 to drive the first lead screw 33 to rotate, thereby driving the first slider 34 to slide on the guide rod 32. The two supports 31 are driven by the first slider 34 to slide with the same amplitude, thereby driving the mechanical part to displace horizontally and achieving the horizontal displacement adjustment of the drilling position. Control the rotation of the third motor 85 by the single-chip microcomputer 6.
