Abstract
The utility model relates to a chamfering tool for an inner hole of a work piece. The chamfering tool comprises a tool mounting seat and a rose reamer, wherein an axial mounting hole and a radial through hole are formed in the tool mounting seat, the radial through hole in the tool mounting seat comprises a straight hole section and a spherical hole section, the spherical hole section is directly communicated with the axial mounting hole, a steel ball is arranged in the spherical hole section, a lock screw extends into the radial through hole in the tool mounting seat and is in threaded connection with the straight hole section of the radial through hole, a steel ball is compressed in a spherical hole, an arc-shaped groove is formed in the circumferential surface of the chamfering knife, one end of the chamfering knife is inserted into the axial mounting hole, after the steel ball is pressed in the spherical hole through the lock screw, the steel ball is sunken into the arc-shaped groove in the chamfering knife. The chamfering tool for the inner hole of the work piece is capable of quickly removing burrs at an orifice in the back of a flange mounting hole, and has the characteristic of high precision for chamfering the inner hole.
Description
Technical field
The utility model relates to a kind of inner hole of workpiece chamfering tool.
Background technology
For the flange mounting hole on expansion shape part, the back side of installing hole is in hemi-closure space, adopt round file cutter, the manual burr of removing on flange mounting hole of triangular scraper, limited by operating space, burr is removed not thorough, and can only remove the burr at flange installed surface aperture place, can not remove the burr at aperture place, the flange back side, the quality of part can not be guaranteed; Use angle scraper to remove the burr on aperture, although can remove the burr on two sides, aperture simultaneously, time of removing burr is long, labour intensity is large, it is low to make efficiency, causes the manufacturing expense of part high.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of simple in structure, the inner hole of workpiece chamfering tool that can remove fast the burr at aperture place, the flange mounting hole back side, and the utility model has the advantages that to the chamfering of endoporus precision is high simultaneously.
The technical scheme solving the problems of the technologies described above is as follows:
Inner hole of workpiece chamfering tool, comprise tool fitting, rose reamer, tool fitting is provided with axial installing hole and radial direction through hole, radial direction through hole on described tool fitting is made up of straight hole section and spherical pore section, described spherical pore section is directly communicated with axial installing hole, in spherical pore section, be provided with steel ball, lock-screw extend in the radial direction through hole of tool fitting, after being threaded with the straight hole section of radial direction through hole, steel ball is pressed in spherical pore, the periphery of described rose reamer is provided with deep-slotted chip breaker, one end of rose reamer is inserted in axial installing hole, after described steel ball is pressed in spherical pore by lock-screw, steel ball is trapped in the deep-slotted chip breaker on rose reamer.
Adopted such scheme, one end of rose reamer is inserted in axial installing hole, after described steel ball is pressed in spherical pore by lock-screw, steel ball is trapped in the deep-slotted chip breaker on rose reamer.By such mode, inner hole of workpiece chamfering tool is clamped, because the height of the radial direction through hole on cutter is consistent, and the diameter of steel ball is consistent, therefore, taking the axial line of tool fitting as boundary, its both sides are consistent apart from the distance of steel ball, thereby, after rose reamer is compressed by steel ball, the positioning precision of the rose reamer improving, while utilizing the utility model to carry out chamfering to inner hole of workpiece, there is the feature that precision is high, also can remove rapidly the burr in aperture simultaneously.
The end face contacting with steel ball of described lock-screw is concave spherical surface.This way of contact, can reduce the wearing and tearing between lock-screw and steel ball, and the contact area of lock-screw and steel ball is large simultaneously, contributes to steel ball to hold out against.
One end of described tool fitting is also provided with the screwed hole being communicated with axial installing hole, the bolt that is threaded in this screwed hole, and the axial end of rose reamer is withstood in one end of this bolt.After the length that rose reamer reaches the part of axial installing hole is adjusted, by bolt, the axial end of rose reamer is held out against, prevent rose reamer being axially subjected to displacement along tool fitting.
Brief description of the drawings
Fig. 1 is inner hole of workpiece chamfering tool structural representation of the present utility model;
1 is tool fitting, and 2 is rose reamer, and 3 is steel ball, and 4 is lock-screw, and 5 is deep-slotted chip breaker, and 6 is screwed hole, and 7 is bolt.
Detailed description of the invention
With reference to Fig. 1, a kind of inner hole of workpiece chamfering tool of the present utility model, comprises tool fitting 1, rose reamer 2, and tool fitting is provided with axial installing hole and radial direction through hole.Radial direction through hole on described tool fitting is made up of straight hole section and spherical pore section, described spherical pore section is directly communicated with axial installing hole, in spherical pore section, be provided with steel ball 3, lock-screw 4 extend in the radial direction through hole of tool fitting 1, after being threaded with the straight hole section of radial direction through hole, steel ball 3 is pressed in spherical pore.The periphery of described rose reamer 2 is provided with deep-slotted chip breaker 5, and one end of rose reamer 2 is inserted in axial installing hole, and after described steel ball 3 is pressed in spherical pore by lock-screw 4, steel ball 3 is trapped in the deep-slotted chip breaker 5 on rose reamer.The end face contacting with steel ball 3 of lock-screw 4 is concave spherical surface.One end of tool fitting 1 is also provided with the screwed hole 6 being communicated with axial installing hole, the bolt 7 that is threaded in this screwed hole, and the axial end of rose reamer 2 is withstood in one end of this bolt 7.
