Description
Technical field
A kind of once-forming cutter for the cutting of deep bore hole is the utility model is related to, belongs to bore hole cutting field.
Background technology
Traditional handicraft is generally utilized in knife bar front end and vertically fixes single knife when carrying out Boring to cylindrical member
Piece, cylindrical member is rotated at a high speed, after the radial feed amount for adjusting blade, control knife bar to the axially opposing fortune in cylindrical member inner chamber
It is dynamic, realize Boring.The depth of each radial feed amount of the technique is smaller, usually 3 to 8 millimeters, holds when the depth of cut is excessive
Easily there is inner chamber to quiver the scenes such as line, spring knife.For heavy caliber cylindrical member deep Boring when, because working depth is deeper, one
Secondary feed can not be completed, it is necessary to which every time after small wall thickness cutting, multiple axial feed could be completed after adjusting radial feed amount, work
Efficiency is low.And in repeatedly adjustment radial feed amount, mismachining tolerance can be increased, influence crudy.
Utility model content
The purpose of this utility model is to solve the deep bore hole that traditional hilted broadsword chip architecture cutter carries out heavy caliber cylindrical member
During processing, the shortcomings of operating efficiency is low, crudy is poor be present, and a kind of once-forming knife for the cutting of deep bore hole is provided
Tool.
The purpose of this utility model is achieved through the following technical solutions：
A kind of once-forming cutter for the cutting of deep bore hole of the present utility model, including blade, multi-blade cutterhead, knife
Bar, knife pedestal, adapter sleeve, tailstock；
Multi-blade cutterhead is cylindrical structure, and the side wall of multi-blade cutterhead is radially provided with multiple blade mounting holes, blade peace
It is in axially spaced-apart and circumference uniform distribution that hole, which is filled, in the distribution of multi-blade cutterhead side wall, and the middle part of each blade mounting holes is to axially forward
It is provided with screw lock hole；
Blade is arranged in each blade mounting holes of multi-blade cutterhead, by the locking screw for being axially screwed into screw lock hole
Nail, each blade is locked；The blade lengths installed on multi-blade cutterhead, it is incremented by successively from front to back, wherein, front end
Length of the cutter head of blade away from multi-blade cutter head center matches with workpiece blank internal bore radius, and the cutter head of rearmost end blade is away from more
The length of blade cutter head center matches with finished workpart internal bore radius；The rear end of multi-blade cutterhead and the front end of knife bar are fixed,
The rear end of knife bar is connected by adapter sleeve with tailstock.The middle part of knife bar ensures the steady of process knife bar by knife stage supports
It is fixed.
The course of work
Workpiece blank is fixed on to the front end of cutter multi-blade cutterhead, makes the axle center of workpiece blank and the axle of multi-blade cutterhead
The heart is consistent, rotational workpieces blank, and by workpiece blank to cutter side axial feed, the knife of front end blade on multi-blade cutterhead
Head first contact workpiece blank end, workpiece blank while rotation while axial feed motion under, on multi-blade cutterhead most before
Blade is held to complete the cutting of small wall thickness, when workpiece blank axial feed to its ends contact is to second blade, two cuttves
The cutter head of piece continues to cut from the position after first blade cut, continues to complete the cutting of small wall thickness, until last a piece of knife
Piece contacts the end of workpiece blank；Each blade forms stepped synchronous cutting, workpiece blank axial direction to the inwall of workpiece blank
Traveling can once complete deep bore hole machining.
Beneficial effect
Forming tool of the present utility model, it is simple in construction, it is easy to adjust, when being cut for deep bore hole can time processing into
Shape, operating efficiency are high；Before cutting, each blade installation site has been fixed, and in cutting, each blade of circle distribution is simultaneously
Contact with workpiece inner wall, support each other, avoid knife bar seismism in working angles, effectively increase crudy.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model forming tool；
Wherein, 1- blades；2- multi-blade cutterheads；3- knife bars；4- knife pedestals；5- adapter sleeves；6- tailstocks.
Embodiment
Content of the present utility model is further described with reference to the accompanying drawings and examples.
Embodiment
A kind of once-forming cutter for the cutting of deep bore hole of the present utility model, as shown in figure 1, including blade 1, multitool
Piece cutterhead 2, knife bar 3, knife pedestal 4, adapter sleeve 5, tailstock 6；
Multi-blade cutterhead 2 is cylindrical structure, and the side wall of multi-blade cutterhead 2 is radially provided with four blade mounting holes, blade
Mounting hole is in axially spaced-apart and circumference uniform distribution in the distribution of the side wall of multi-blade cutterhead 2, and the middle parts of each blade mounting holes is to axial direction
Screw lock hole is provided with forward；
Four blades are arranged in each blade mounting holes of multi-blade cutterhead 2, by being axially screwed into screw lock hole
Lock-screw, each blade is locked；The blade lengths installed on multi-blade cutterhead 2, it is incremented by successively from front to back, its
In, length of the cutter head of front end blade away from the center of multi-blade cutterhead 2 matches with workpiece blank internal bore radius, rearmost end blade

The stabilization of work process knife bar.
The course of work
Workpiece blank is fixed on to the front end of cutter multi-blade cutterhead 2, makes axle center and the multi-blade cutterhead 2 of workpiece blank
Axle center is consistent, rotational workpieces blank, and by workpiece blank to cutter side axial feed, front end blade on multi-blade cutterhead 2
Cutter head contact the end of workpiece blank first, workpiece blank is while in rotation under the motion of axial feed, on multi-blade cutterhead 2
Front end blade completes the cutting of small wall thickness, when workpiece blank axial feed to its ends contact is to second blade, second
The cutter head of piece blade continues to cut from the position after first blade cut, continues to complete the cutting of small wall thickness, until last
The end of piece blade contact workpiece blank；Each blade forms stepped synchronous cutting, workpiece blank to the inwall of workpiece blank
Deep bore hole machining can once be completed by axially advancing.
