Abstract

The utility model provides a cutter for drilling composite chamfers of cylindrical bolt parts, belongs to a cutter for machining parts, and particularly relates to a special cutter for drilling composite chamfers on the end surfaces of the cylindrical bolt parts. One end of a cutter body is provided with a chamfer cutter, the central axis of the cutter body with the chamfer cutter is provided with a blind hole in which a drill bit is arranged; and a fastening screw for pressing the drill bit in the blind hole is arranged on the cutter body. The cutter solves the defects that the cylindrical bolt parts with inner holes at a machining end surface and having a chamfer requirement on outer circles can be machined by using a drill machine and a lathe and is finished by two steps; and the cutter is arranged on a table drill, and can finish the machining of pin inner holes and an outer circle chamfer for one time when the cylindrical bolt parts with the inner holes at the machining end surface and having the chamfer requirement on the outer circles are machined, the working efficiency is improved by one time, the equipment investment is reduced, and the production cost of a factory is reduced as well as the labor intensity is reduced.

Description

A kind of cutter for the compound chamfering of straight pin class drilling part
Technical field
The utility model belongs to a kind of parts for machining, is specifically related to the hole dedicated tool of compound chamfering of a kind of straight pin class part end face.
Background technology
In machining, usually when the processing end face has endoporus, cylindrical that the straight pin class part of chamfering requirement is arranged, endoporus gets out with drill bit usually, outer rounded corner lathe tool car need to use drilling machine and two process equipments of lathe, is divided into for two steps to finish, complex procedures, efficiency is low, because this type of straight pin class part output is large, has increased the production cost of factory and workman's labour intensity.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of cutter that is used for the compound chamfering of straight pin class drilling part that can once finish boring, chamfering process.
The technical solution of the utility model is: an end of tool bodies is equipped with rose reamer, has the tool bodies central axis of rose reamer one end that one blind hole is arranged, and the in-built drill bit of blind hole is equipped with on the tool bodies for the holding screw that compresses drill bit in the blind hole.
Described rose reamer is the cutter of falling the exterior angle or the cutter of falling the interior angle.
The utility model is installed on bench drill, at the processing end face endoporus is arranged, when cylindrical has the straight pin class part of chamfering requirement, bearing pin endoporus and outer rounded corner can be processed at one time, work efficiency doubles, and has reduced equipment investment, has reduced the production cost of factory and workman's labour intensity.
Description of drawings
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is the structural representation of straight pin class part.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
The class of straight pin shown in Fig. 1 part is the straight pin class part that end face has endoporus, cylindrical to have chamfering to require.
Among Fig. 2, the utility model is comprised of tool bodies 1, the cutter of falling the exterior angle 2, drill bit 4, holding screw 5, be welded with the cutter of falling the exterior angle 2 in tool bodies 1, simultaneously drill bit 4 is installed in the tool bodies in the blind hole 3, with the fixing axial location of holding screw 5, thereby realize that boring, outer rounded corner once finish.

Claims (2)

1. cutter that is used for the compound chamfering of straight pin class drilling part, it is characterized in that: an end of tool bodies is equipped with rose reamer, have the tool bodies central axis of rose reamer one end that one blind hole is arranged, the in-built drill bit of blind hole is equipped with on the tool bodies for the holding screw that compresses drill bit in the blind hole.
2. the cutter for the compound chamfering of straight pin class drilling part according to claim 1, it is characterized in that: described rose reamer is the cutter of falling the exterior angle, or the cutter of falling the interior angle.
