Multifunctional positioning and clamping device for residual materials of drill gang

The invention discloses a drill row excess material multifunctional positioning and clamping device which comprises a body, the body is provided with a guide hole, a first positioning hole and a pressing hole, the axis of the guide hole, the axis of the first positioning hole and the axis of the pressing hole are arranged in a coplanar mode, and the hole diameter of the guide hole, the hole diameter of the first positioning hole and the hole diameter of the pressing hole are equal. The first positioning hole is connected with a first positioning pin, the pressing hole is connected with an expansion bolt, the first positioning pin is in interference fit with the first positioning hole, and the expansion bolt is detachably connected to the pressing hole. By arranging the clamping device, the problem that in the drilling process, a drill bit is prone to deviation when tangent holes in the inner shape and the outer shape are drilled is effectively solved. 本发明公开了一种钻排余料多功能定位夹紧装置，包括本体，所述本体设有导向孔、第一定位孔和压紧孔，所述导向孔的轴线、第一
