The axle center of the rectangle protruding part is provided with threaded hole, the head end of positioning pin is fixedly connected with fixing bolt；Institute
Stating fixing bolt can coincide with threaded hole.
The cross-sectional area of the positioning pin head end is more than the cross-sectional area of cutter body head end rectangular aperture.
The cutter is at least provided with 2 or more.
Above-mentioned technical proposal is beneficial in that：
The utility model provides a kind of outer diameter process tool, and when processing has been picked out according to the requirement outer diameter of workpieces processing
The cutter body in corresponding Inner footpaths（The Inner footpaths of load-bearing part）It is fixedly connected with handle of a knife, workpiece is fixed on Work fixing device
On, and then the center of circle of part workpiece and the correction of the center of circle of cutter body drive cutter body towards under workpiece to it using handle of a knife
Pressure, you can process the workpiece consistent with load-bearing part internal diameter；Work piece high-speed rotation is not required, also avoids due to using single knife
Problem caused by the radial feed of tool, processing method compared with prior art, the process tool of the utility model can substantially really
Machining accuracy is protected, due to being distributed in using multiple cutters on the circumferential surface of load-bearing part, so it is also ensured that the processing of workpiece
The defects of face is not in processing scratch, and positioning pin is provided in cutter body, positioning pin is fed in cutter body
Stationary positioned can also be played the role of to workpiece in the process, further ensure machining accuracy.
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is the utility model part of the embodiment, instead of all the embodiments.Based on the embodiment in the utility model, ordinary skill
Personnel's all other embodiments obtained without making creative work belong to the scope of the utility model protection.

Specific embodiment
Embodiment 1
A kind of outer diameter process tool, including cutter 1, handle of a knife 2 and cutter body 3；3 inner hollow of cutter body,
3 head end of cutter body and tail end are both provided with opening, and the cross-sectional area of cutter body head end opening 30 is less than cutter body tail end
The cross-sectional area of opening 31；The cutter is distributed along the even circumferential of 1 cutter body tail end opening 31, and one end of handle of a knife 2 can
It is detachably fixedly arranged in cutter body head end opening 30, one end that handle of a knife 2 stretches into cutter body 3 is removably connected with positioning pin
4；The internal diameter of the cutter body 3, which is equal to corresponding workpiece, need to process outer diameter.
Specifically, the head end in the cutter body 3 is fixedly connected with load-bearing part 32, the diameter of the load-bearing part 32 is more than
The diameter of cutter body 3, the cutter 1 are distributed along the even circumferential of 32 tail end of load-bearing part；Internal diameter of the load-bearing part 32 etc.
Outer diameter need to be processed in corresponding workpiece；Setting in this way, due to being to be fixed on using load-bearing part on cutter body, cutter is solid again
