Specific embodiment
A kind of interchangeable drill body of side chain axial tightening, including drill body 2 and alloy cutter head 1 lean on the drill body 2
One end center of nearly alloy cutter head 1 is provided in the axial direction with installing blind, and connection alloy cutter head 1 is arranged in the installing blind
Positioning pin 3 offers the first screw fastening tieholen 2-1 and the second screw thread being connected to installing blind on the side wall of drill body 2
Locking hole 2-2, the side of positioning pin 3 offer corresponding with the first screw fastening tieholen 2-1 and the second screw fastening tieholen 2-2
First is bolted in the first U-shaped U-shaped notch 3-2 of notch 3-1 and second, the U-shaped notch 3-1 of the first screw fastening tieholen 2-1 and first
Lock-screw 4 is bolted with the second lock-screw 5 in the U-shaped notch 3-2 of second screw fastening tieholen 2-2 and second.
It is connected between the alloy cutter head 1 and positioning pin 3 using helicitic texture, the rear end middle position of alloy cutter head 1
Integrally formed with external thread rod 1-1, the internal thread hole 3-3 with external thread rod 1-1 cooperation is provided on positioning pin 3.
The front end of first lock-screw 4 and the second lock-screw 5 all has a tapered configuration.
Eccentricity is arranged the opening of the U-shaped notch 3-2 of the U-shaped notch 3-1 and second of described first outwardly, and first is U-shaped scarce
The opening of mouth 3-1 has the width for being greater than 4 diameter of the first lock-screw.
The positioning V-shaped face of mutual positioning is provided on the drill body 2 and alloy cutter head 1.
It is as shown in Figure 1, Figure 2 and Figure 3: when assembly uses, firstly, positioning pin 3 and alloy cutter head 1 are passed through external screw thread
