Description
Technical Field
The utility model relates to a cutter technical field specifically says so, is a countersink of combination locating surface.
Background
The countersink drill is a processing tool for scraping an end face of a hole processed on a workpiece or cutting out a conical or cylindrical counter bore, for drilling of some parts, the position of the drilled hole and the depth tolerance of the hole are strict, the drilled hole must be processed by a numerical control processing center, if the number of the numerical control processing centers in a workshop is limited, the capacity cannot be kept up, and other manual machine tools are in an idle state, so that resources cannot be reasonably utilized.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: to the problem and not enough of existence among the above-mentioned prior art, the utility model aims at providing a counter bit of combination locating surface. The drill bit can be used on a common manual machine tool, not only can reach the precision of a numerical control machining center, but also can improve the productivity.
The technical scheme is as follows: in order to achieve the purpose, the countersink drill with the combined positioning surface comprises a guide part, a drill body, a positioning ring and a handle part, wherein the guide part, the drill body and the handle part are integrally formed, the guide part is arranged at the front end of the drill body, and the positioning ring is locked on the drill body through a nut.
Furthermore, the guide part comprises a first guide cylinder and a second guide cylinder, the second guide cylinder is arranged between the first guide cylinder and the drill body, and the diameter of the first guide cylinder is smaller than that of the second guide cylinder.
Further, the drill body is provided with an end blade, an outer diameter blade and a chamfer blade, the outer diameter blade is arranged between the end blade and the chamfer blade, and the chip groove is arranged on the rear side of the chamfer blade.
Further, the outer diameter blade is perpendicular to the end blade, and an included angle formed by the chamfer blade and the outer diameter blade is 45 degrees.
Furthermore, the drill body is provided with a locking surface for mounting the positioning ring.
Furthermore, a positioning hole matched with the drill body is formed in the positioning ring, and a threaded hole is formed in the positioning ring.
Further, the handle is a morse handle.
Above-mentioned technical scheme can see out, the beneficial effects of the utility model are that:
a counter boring of combination locating surface, the brill body is last to have guide part and holding ring, through the direction of guide part and the terminal surface location effect of holding ring for the degree of depth and the position of counter boring are guaranteed, make original part size of controlling machine tool control change by cutter control, have reduced the requirement to the lathe, even use ordinary manual lathe also can process, have improved the utilization ratio of ordinary lathe, the productivity obtains improving.
