Abstract
The utility model relates to a boring cutter which comprises a cutter bar, a cutter head and a cutter blade. The boring cutter provided by the utility model is characterized in that a cutter head mounting slot and a mounting bolt hole are formed on the cutter bar, and the center line of the cutter head mounting slot and the center line of the cutter bar are on a same plane; the cutter head is arranged inside the cutter head mounting slot and fastened by a bolt; and the cutter blade is an external turning tool which is fastened on the cutter head through a cutter blade press plate. The boring cutter has the advantages of simple structure, good rigidity, low cutter blade loss, high machining precision and long service life. By improving the assembling method of the cutter head and the cutter blade, the strength and cutting speed of the cutter bar and the cutter head are increased. The external turning tool is adopted with no need of manual scraps, so that the safety is good and the machining efficiency is doubled. The service life of the cutter blade is increased by 10 times.
Description
Technical field
The utility model relates to a kind of cutter, is specifically related to a kind of borer that endoporus is carried out boring.
Background technology
Borer processing is adopted in the boring of profound endoporus usually, and borer is made up of knife bar, blade and cutter head.The cutter head of this borer and knife bar decentraction, the eccentric installation, the center line of point of a knife and knife bar at grade, blade employing lever is clamped on the cutter head.The shake cutter is serious in this borer process, and inner bore surface roughness is poor; Chip removal is not smooth, and iron filings twine knife bar easily, and interior hole dimension is destroyed; Iron filings twine knife bar, and the blade that makes bore hole use is struck off easily, and the blade loss is big; Average every blade can only be processed 2～3 parts, has increased processing cost, and artificial iron filings in the hole are ticked can effectively reduce blade loss and processing cost; But when ticking iron filings; Because little, the hole depth in aperture contacts knife bar and cutter head easily, this has brought very big potential safety hazard to the operator again.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming that above-mentioned cutter exists, and a kind of simple in structure, good rigidly is provided, the blade loss is little, machining accuracy is high, the borer of long service life.
The borer of the utility model comprises knife bar, cutter head and blade, it is characterized in that: described knife bar is provided with the cutter head mounting groove and screw is installed, and the center line of cutter head mounting groove and the center line of knife bar are at grade; Cutter head is installed in the cutter head mounting groove, is tightened up by screw; Blade is a billmpse tool, by blade pressuring plate with blade pressing on cutter head.
Simple in structure, the good rigidly of the utility model, the blade loss is little, machining accuracy is high; The intensity of knife bar and cutter head is good, long service life; Adopt billmpse tool not need artificial hook bits, security is good, and cutting speed is high, and working (machining) efficiency improves 2 times, and blade improves 10 times service life.
