The big end connection clip scapus of transition post.
Further, the left end and positioning head of described clamp post, drilling post, transition shoulder post use special material system
Into the left end of described clamp post accounts for the 1/14 of clamp post overall length, the equal length of the drilling post and clamp post left end.
Further, before drilling, first by drill bit clamping to drilling machine, and processed workpiece is positioned, it is determined that brill
Hole site, pushes drill bit and carries out boring positioning, then the cutting drilling blade on positioning head will cut gold during rotation
Belong to material, chip taken out of by cutting slot, with the drilled depth in hole, and cutoff edge will cutting hole inwall, the inwall of device to hole
Secondary ream is carried out, so as to process the hole of inner wall smooth.
Compared with prior art, the beneficial effects of the utility model are：Using the drill bit of integrative-structure, positioning head cone-apex angle
Greatly, it is to avoid the top frequently disconnected point of positioning head, cause position error big, drilling post is short, itself and clamp intercolumniation frustum of a cone transition, and bore
The cutting slot cut on post is seamlessly transitted with transition shoulder intercolumniation using arc, and sound construction is not easily broken damage, service life
Long, while cutting drilling blade is located on positioning curved face, drilling speed is fast, and cutoff edge, which substitutes reamer, can promote drilled inwall
It is smooth, secondary positioning is eliminated, the precision for processing hole is higher, the quality in processing hole is further improved.
