[0031] A drilling and tapping combined machine, the working principle is as follows:

[0032] The hardware to be processed is placed on the placement table 404, and the hand wheel 406 is turned to drive the bidirectional screw rod 405 to rotate. The rotation of the bidirectional screw rod 405 drives the two clamping blocks 407 to move towards each other to clamp and fix the hardware. During the initial processing, the workpiece is fixed only on one placement table 404, and the other side is not placed. The second screw rod 402 is driven to rotate by the third motor 401, and the second screw rod 402 drives the sliding block 403 to move. The sliding block 403 drives the placement table 404 to move, thereby driving the workpiece to adjust the position. Subsequently, the first transmission rod 205 is driven to rotate by the first motor 204, and the rotation of the first transmission rod 205 drives the first gear 206 to rotate. The first gear 206 drives the second gear 208 meshing therewith to rotate, and the second gear 208 drives the first screw rod 207 to rotate. The installation directions of the two first screw rods 207 are opposite, so that the two mounting parts 209 move towards each other synchronously, thereby driving the drill bit 5 and the tapping head 6 to adjust the position.

[0033] After the positions are corresponding, the second transmission rod 302 is driven to rotate by the third motor 401, the second transmission rod 302 drives the first bevel gear 304 to rotate, the first bevel gear 304 drives the second bevel gear 305 meshing therewith to rotate, the rotation of the second bevel gear 305 drives the cross rod 306 to rotate, the cross rod 306 drives the cylindrical rod to rotate, the rotation of the cylindrical rod drives the third bevel gear 308 to rotate, the rotation of the third bevel gear 308 drives the fourth bevel gear 309 meshing therewith to rotate, the rotation of the fourth bevel gear 309 drives the mounting rod 210 to rotate, and then drives the drill bit 5 and the tapping head 6 to rotate;

[0034] Then, the electric push rod 202 is started to drive the connecting block 203 to move, and the movement of the connecting block 203 drives the drill bit 5 and the tapping head 6 to move downward, thereby performing drilling processing. At this time, only one workpiece is placed. After the drilling of this workpiece is completed, a new workpiece is fixed on another placement table 404, and the drilled workpiece is adjusted to the bottom of the tapping head 6 by the third motor 401, and the new workpiece is adjusted to the bottom of the drill bit 5 by the third motor 401. At this time, when the electric push rod 202 drives the connecting block 203 downward, the two workpieces are processed at the same time;

[0035] After the processing is completed, the electric push rod 202 rises, the tapped workpiece is removed, and a new workpiece is re-fixed, and the workpiece position is adjusted by the third motor 401, and the work is repeated.
