The drilling depth consistency can be ensured by the action accuracy of the second cylinder 12 and the first cylinder 6.

[0036] Working principle: The adjusting foot 17 is locked to the frame 1 with screws. The screws pass through the strip hole 19 and are threaded into the threaded hole 18.

The second motor 14 drives the turntable clamp 15 to rotate in increments, so that each clamping hole 16 is aligned with the drill chuck 29 in sequence, realizing the cyclic switching of clamping, drilling and unloading stations, eliminating the time loss of single-station downtime for material change. Two sets of collection frames 13 are respectively for collecting debris generated in different processing stages. The operator can complete the cleaning by pulling horizontally along the track 20. The first motor 5 is connected to the transmission device in the transmission box 4 through the belt and belt pulley. The first motor 5 drives the spindle 10 to rotate at high speed via belt drive. The spindle 10 is in a sliding connection with the transmission device, realizing the dual motion coupling of rotary cutting and axial feed of the drill chuck 29. The first cylinder 6 pushes the connecting plate 9 to move the spindle 10 down quickly to approach the workpiece. After drilling is completed, the first cylinder 6 can drive the spindle to rise quickly to retract the tool, avoiding affecting the switching of the turntable fixture 15 and improving processing efficiency. The second cylinder 12 converts linear motion into precise axial displacement of the shift sleeve 27 through the mechanical transmission of the shift fork 26 and the shift groove 28, realizing the drilling action and the retraction and chip removal action. The action accuracy of the second cylinder 12 and the first cylinder 6 can ensure the consistency of drilling depth.
