fixing: placing a workpiece in a U-shaped hole in the middle of a diameter adjusting block, and adjusting the distance between the diameter adjusting blocks to clamp the workpiece front and back; the adjusting nut on the length adjusting block is matched and connected with the threaded hole on the diameter adjusting block, so that the distance between the length adjusting blocks is equal to the length of the workpiece, and the workpiece is clamped leftwards and rightwards; the position of the workpiece is adjusted through the X-direction adjusting mechanism and the Y-direction adjusting mechanism, so that the cutter is positioned right above the position of the workpiece needing drilling;
transmission: the first motor works, the small belt wheel rotates at a high speed under the action of friction force, the small gear is driven to rotate at a high speed through the first transmission shaft, and the large gear meshed with the small gear is driven to rotate at a high speed to enable the second transmission shaft to rotate at a high speed; the third transmission shaft rotates at a high speed under the action of the second transmission shaft to drive the first conical teeth to rotate at a high speed in the vertical direction, so that the third transmission shaft is forced to be meshed with the first conical teeth to rotate the second conical teeth at a high speed, and the rotating force in the vertical direction is transmitted to the horizontal direction, so that the fourth transmission shaft and the cutter rotate at a high speed in the horizontal direction;
drilling: the second motor works, the screw rod is rotated through the speed reducer, the ball sliding table is driven to be matched with the guide rail to move downwards, the stable drilling device is made to move downwards, the cutter rotates downwards at a high speed, and a workpiece is drilled.
