reversing the tap clamp 17 will drive the tap to reverse and the tap reverse will expel the cutting chips in the borehole.
For the reverse rotation of the gland 14, since the connecting cylinder 18 is fixed on the cylinder liner 7, the sealing flange 20 fixedly connected with the connecting cylinder 18 is in a fixed state, the guide rod 21 fixedly connected with the sealing flange 20 is in a fixed state, the guide pipe 28 on the guide rod 21 is in a fixed state, the piston 19 fixedly connected with the guide pipe 28 is also in a fixed state, the slide block 26 fixedly connected with the piston 19 is also in a fixed state, the inclined slide groove 25 is also reversed along with the reverse rotation of the gland 14, and the slide block 26 is gradually reset into the inclined slide groove 25 under the elastic force of the compression spring 22.

Setting friction force to enable F1 to be more than F3 to be more than F2;
in the process of drilling and tapping by rotating the tap, along with the increase of the depth of the tap entering the part, cutting scraps in the drill hole are accumulated, and the cutting force required by drilling and tapping of the tap is gradually increased, so that the cutting force F provided by the tap clamping part 17 to the tap is also increased;
since the cutting force F output by the tap clamping part 17 is provided by the friction force F2 between the gland 14 and the second elastic washer, when the tap reaches the maximum cutting force F3, the tap cannot be driven to rotate continuously due to F2< F3, and the tap stops rotating.
After the tap stops rotating, the tap is clamped and fixed on the second face gear 9 through the tap clamping part 17, and when the tap stops rotating, the second face gear 9 also stops rotating, and the gland 14 also stops rotating.
After the tap stops rotating, the first end face gear 8 still drives the connecting cylinder 18 to rotate through the friction force F1, the connecting cylinder 18 rotates to drive the sealing flange 20 to rotate, the sealing flange 20 rotates to drive the piston 19 to rotate through the guide rod 21 and the guide tube 28, and the piston 19 rotates relative to the gland 14 because the gland 14 stops rotating at the moment, the sliding block 26 slides outwards in the inclined sliding groove 25, the sliding block 26 drives the piston 19 to move in the direction away from the inclined sliding groove 25 on the connecting cylinder 18 in the process of sliding out of the inclined sliding groove 25, the guide tube 28 is driven to axially move in the process of sliding out of the inclined sliding groove 25, and the guide tube 28 slides on the guide rod 21 in the axial moving process, so that the compression spring 22 sleeved on the guide rod 21 is compressed, and the movement is stopped until the guide tube 28 moves to the maximum distance.
In the process that the piston 19 is far away from the inclined sliding groove 25, the pressure in the inclined sliding groove 25 is reduced, the pressure in the flow channel 23 is increased, the plunger 24 slides in the flow channel 23 and is far away from the connecting cylinder 18 along the sealing flange 20 in the radial direction, as shown in fig. 13, the plunger 24 is far away from the connecting cylinder 18 and enters an opened limit groove 701 on the cylinder sleeve 7, at this time, part of the plunger 24 is positioned in the flow channel 23, part of the plunger 24 is positioned in the limit groove 701, and the connecting cylinder 18 can be regarded as being fixed on the cylinder sleeve 7.
When the connecting cylinder 18 is fixed on the cylinder liner 7, as shown in fig. 7-8, the spur gear 10 is rotatably installed in the connecting cylinder 18, and the first end gear 8 and the second end gear 9 are meshed with the spur gear 10, and the connecting shaft 11 continuously drives the first end gear 8 to rotate due to the driving force provided by the connecting shaft 11 being greater than F1, the first end gear 8 drives the second end gear 9 to rotate reversely through the spur gear 10, and the reversing of the end gear 9 drives the tap clamping portion 17 and the gland 14 to rotate reversely, wherein:
the screw tap clamping part 17 is reversed, the screw tap clamping part 17 can drive the screw tap to be reversed, the screw tap can discharge cutting chips in a drilling hole, after the cutting chips are discharged, the cutting force born by the screw tap rotation can be reduced, and the cutting force F required by the screw tap clamping part 17 can be reduced.
For the reverse rotation of the gland 14, since the connecting cylinder 18 is fixed on the cylinder liner 7, the sealing flange 20 fixedly connected with the connecting cylinder 18 is in a fixed state, the guide rod 21 fixedly connected with the sealing flange 20 is in a fixed state, the guide pipe 28 on the guide rod 21 is in a fixed state, the piston 19 fixedly connected with the guide pipe 28 is also in a fixed state, the slide block 26 fixedly connected with the piston 19 is also in a fixed state, the inclined slide groove 25 is also reversed along with the reverse rotation of the gland 14, and the slide block 26 is gradually reset into the inclined slide groove 25 under the elastic force of the compression spring 22.
After the working steps are finished, cutting scraps in the drill hole are discharged through screw tap reversing, so that the cutting force required by the screw tap in the drill hole is reduced, and the screw tap can continue tapping the drill hole.
Compared with the prior art that the cutting scraps in the drill hole can be discharged only after the machine tool is stopped, the drilling tapping machine provided by the invention can discharge the cutting scraps in the drill hole without stopping in the drilling tapping working process, so that the time for stopping the machine tool for removing scraps is saved, and the tap can be prevented from being damaged due to the fact that the bearing cutting force exceeds the maximum straight of the tap.
