the guide pillar 2 is of a cylindrical structure, a groove used for clamping the countersink drill 1 is formed in one end of the guide pillar 2, and the other end of the guide pillar 2 is clamped on the pneumatic drill.
Optionally, the cutting edge of the cutting edge is arranged on the side of the cutting edge facing the other end of the guide post 2.
Optionally, the cylinder edge is provided with three cutting edges.
Optionally, the diameter of the end of the guide post 2 provided with the groove is larger than the diameter of the other end of the guide post 2.
Optionally, a groove structure arranged at one end of the guide pillar 2 is matched with the countersink drill 1.
Optionally, the length of the cutting edge of the countersink 1 is set according to the area of the countersink surface.
Optionally, the material of the countersink 1 is M42 steel.
Optionally, the material of the guide pillar 2 is 45 # steel.
The beneficial effect advantage of this application is: by using the tool, the work originally completed by workers with high operation skills for a long time is changed into simple and rapid work, the efficiency is increased, the skill requirement of operators is reduced, the production efficiency is improved, and the production cost is reduced.

Detailed Description
Example one
The application provides an end face reverse countersink drill, end face reverse countersink drill includes countersink drill 1 and guide pillar 2 wherein:
the countersink drill 1 is of a hollow cylinder structure, at least two cutting edges are arranged on the edge of the cylinder, the plane extending direction of each cutting edge is parallel to the axis of the guide pillar 2, and each cutting edge is clamped at one end of the guide pillar 2 through a circular hole in the middle of the cutting edge;
the guide pillar 2 is of a cylindrical structure, a groove used for clamping the countersink drill 1 is formed in one end of the guide pillar 2, and the other end of the guide pillar 2 is clamped on the pneumatic drill.
Optionally, the cutting edge of the cutting edge is arranged on the side of the cutting edge facing the other end of the guide post 2.
Optionally, the cylinder edge is provided with three cutting edges.
Optionally, the diameter of the end of the guide post 2 provided with the groove is larger than the diameter of the other end of the guide post 2.
Optionally, a groove structure arranged at one end of the guide pillar 2 is matched with the countersink drill 1.
Optionally, the length of the cutting edge of the countersink 1 is set according to the area of the countersink surface.
Optionally, the material of the countersink 1 is M42 steel.
Optionally, the material of the guide pillar 2 is 45 # steel.
The beneficial effect advantage of this application is: by using the tool, the work originally completed by workers with high operation skills for a long time is changed into simple and rapid work, the efficiency is increased, the skill requirement of operators is reduced, the production efficiency is improved, and the production cost is reduced.
Example two
The application is realized by the following technical scheme: this instrument is through setting up countersink and drill and guide pillar, through with the guide pillar centre gripping on the pneumatic drill, at the reverse side of needs countersink, wears the guide pillar through the hole, then installs countersink at the terminal surface of needs countersink, guarantees countersink working face and the laminating of product machined surface, starts the pneumatic drill and goes back the pull-back with the pneumatic drill, bores the cutting product surface and reduces bolted connection department intermediate layer thickness, reaches the purpose of control intermediate layer thickness.
The aircraft is after adjusting the gesture of the engine nacelle relative middle and outer wing, need system hole connecting bolt, connecting bolt needs to measure the adjustment to bolted connection department intermediate layer thickness before, concrete method does, when confirming here needs to carry out the dimple processing, at first confirm the dimple degree of depth, then with 2 # spare centre gripping in the picture on the pneumatic drill, it stretches into downthehole to open No. 2 spare from the space one end, guarantee that No. 2 spare stretches out another terminal surface in hole, install No. 1 spare at No. 2 spare end this moment, start the pneumatic drill and draw back, through No. 1 spare cutting product surface, thereby process the thickness that satisfies the requirement with intermediate layer thickness. After the machining is finished, the pneumatic drill is pushed forwards, the No. 1 part is dismounted, the No. 2 part is pulled out of the hole, and the end face dimple is finished.
In conclusion, the method can be used for the end face spot facing in a narrow space in the aircraft manufacturing process, as shown in fig. 1. The application provides an end face reverse countersink drill mainly includes guide pillar and countersink drill. During the use, pass the bolt hole with the guide pillar, then install the countersink on the guide pillar to realize reverse terminal surface countersink.
