Description
Technical field
The present invention relates to a kind of adjustable chamfer boring tool and the method for carrying out Hole chamfering processing, belong to field of machining.
Background technology
Carry out on boring machine workpiece hole both sides chamfering when, generally adopt two kinds of forms, one kind has been carried out with rose reamer
After the chamfering of side, by worktable rotary 180 degree after, in the chamfer machining for carrying out opposite side, and often carry out a chamfering and all need
The measurement of size to be carried out；Another kind is after the chamfering of side is finished down, and cutter is unloaded, in knife bar through after the hole of workpiece,
Again cutter is loaded onto, the chamfering of opposite side is carried out, it is also desirable to carries out the measurement of chamfer dimesion.
When chamfer machining, the material for running into workpiece is harder or local is when having hard spot, the phenomenon of breaks down often occurs.
Content of the invention
The purpose of patent of the present invention is that providing one kind can adjust chamfer dimesion, it is possible to carry out the adjustable of double-side cutting
Chamfer boring tool and the method for carrying out Hole chamfering processing.
Technical solution：
The present invention includes：Handle of a knife, handle of a knife afterbody are radially provided with the groove being engaged with cutter head, perpendicular with the groove side
Handle of a knife pin-and-hole is provided with upwards；Cutter head is polygonized structure, and cutter head bottom is provided with the first pin-and-hole, and the first pin-and-hole is relative with handle of a knife pin-and-hole
Should, the second pin-and-hole is provided with the top of cutter head, the second pin-and-hole top is threadedly coupled with cutting adjustment block, and the cutting adjustment block bottom sets
There is adjusting means, the second pin-and-hole bottom and the first pin-and-hole insertion, cutter head top is provided with the 3rd pin-and-hole, the 3rd pin-and-hole and the second pin-and-hole
Vertically through.
The flat pin-and-hole of the handle of a knife pin-and-hole, its two ends are arc, and upper and lower side is plane.
Fixing pin is installed in first pin-and-hole, the two ends of fixing pin are arc, and upper and lower side is the flat of plane
Structure.
Sliding pin is set in second pin-and-hole, and sliding pin one end wedge structure is provided with radially through groove on lozenges.
Set chi pin in 3rd pin-and-hole, scale pin one end is ramp structure, the other end is sphere, scale pin
On be provided with axially extending bore.
The adjusting means is to be provided with endoporus in cutting adjustment block bottom, sets spring, spring and sliding pin phase in endoporus
Contact.
The cutter head profile is diamond-shaped body structure.
The method that Hole chamfering processing is carried out using adjustable chamfer boring tool, in chamfer machining, one end of sliding pin is by filling
The spring fitted in cutting adjustment block is pressed in the upper plane of fixing pin, is now fixed by knife plate, can be carried out chamfer cutting.
When being worked into work piece and touching scale pin, scale pin by with the inclined-plane of sliding pin to one away from steady pin
The axial force of nail, after sliding pin leaves fixing pin, knife plate can not be fixed, and then knife plate is screwed in the cutter groove of handle of a knife.
After handle of a knife main shaft passes through hole, rotation knife plate makes which reset, i.e., sliding pin lower end is touched with flat face on fixing pin, carries out
Opposite side chamfer machining.The size of chamfering can be realized control, the size of cutting force by replacing scale pin and can pass through
Cut adjustment block to control.
The present invention is placed in handle of a knife groove in cutter head, and is connected by fixing pin, a plane of fixing pin and slip
Pin lower surface contacts, and for transmitting cutting force during processing, the lozenges of sliding pin can make which when cutting adjustment block
After touching workpiece, stress is moved away from the direction of fixing pin backward, so as to reach the purpose of control chamfer dimesion.Cutting is adjusted
Monoblock and spring therein can provide cutter head process when cutting force, when cutting force reach can with compression spring when, sliding pin
Nail is fallen in love, and that is moved away from fixing pin direction, and cutting terminates, so as to protect cutter head and lathe without prejudice.
The present invention can be disposably completed to through hole two in not rotary work-table and workpiece, in the case of not dismantling cutter
The chamfer machining of side end face, it is possible to be sized, without repeated measure chamfer dimesion, convenient processing is time saving and energy saving, and provides
Overload protection, makes processing safer, improve product quality.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
A portion enlarged drawings of the Fig. 2 for Fig. 1；
Fig. 3 is three dimensional structure diagram of the present invention.
Specific embodiment
The present invention includes：Handle of a knife 2, cutter head 3, cutter head profile are diamond-shaped body structure, are provided with groove, with groove phase on handle of a knife 2
Handle of a knife pin-and-hole is provided with vertical direction, and 3 bottom of cutter head is provided with the first pin-and-hole, and head is provided with the second pin-and-hole, and 3 top of cutter head is opened
There is the 3rd pin-and-hole；Cutter head 3 is placed in the groove of handle of a knife 2, is hinged with fixing pin 7 respectively, is slidably connected with scale pin 5, with
Cutting adjustment block 6 is threadedly coupled.Sliding pin 4, scale pin 5 are slidably connected with cutter head 3 respectively, and 2 small end of cutter head is adjusted with cutting
Monoblock 6 is threaded connection, and spring 1 is placed in hole, for providing pretightning force for sliding pin 4, it is ensured that cutter head 3 has enough
Cutting force.The inclined-plane of scale pin 5 is slidably connected with the inclined-plane of sliding pin 4, passes through 8 He of blind rivet between two scale pins 5
Nut 9 is connected, it is ensured that scale pin 5 will not come off from the through hole of cutter head 3.
The handle of a knife pin-and-hole is flat pin-and-hole, and its two ends is arc, and upper and lower side is plane；
Fixing pin is installed in the first pin-and-hole, the two ends of fixing pin are arc, and upper and lower side is the flat structure of plane.
First pin-and-hole is corresponding with handle of a knife pin-and-hole, and the two ends of the fixing pin 7 are arc, and upper and lower side is the flat of plane
Shape structure.
Second pin-and-hole bottom and the first pin-and-hole insertion, set sliding pin 4,4 one end wedge shape knot of sliding pin in the second pin-and-hole
Structure, is provided with radially through groove on lozenges；
3rd pin-and-hole and the second pin-and-hole are vertically through the 3rd pin-and-hole is interior to set chi pin 5, and 5 one end of scale pin is inclined-plane
Structure, the other end are sphere, are provided with axially extending bore on scale pin 5.
Describe cardinal principle in detail：During chamfer machining, when absorption surface is to scale pin 5, it will given chi pin 5 one
Individual axial force, now sliding pin 4 will move to the small end of cutter head, and leave fixing pin 7, now cutter head 3 can be free
Rotate, it is impossible to bear cutting force, processing terminates, so as to control chamfer dimesion.Lathe continues feeding, it will make cutter head 3 screw in knife
In handle 2, after handle of a knife passes through inner hole of workpiece, manually cutter head is resetted, now sliding pin 4 can be in the presence of spring 1
The big end movement of cutter head, after sliding pin 4 touches fixing pin 7, cutter head 3 can carry out the chamfering of workpiece opposite side and add
Work.Therefore by the length of control scale pin 5, it is possible to realize the control to chamfer dimesion size.
When lathe has the requirement of control cutting force, such as lathe is rigidly bad, it is impossible to bear too big cutting force, at this moment
The pretightning force of sliding pin 4 can be given by adjustment cutting adjustment block 6 come correcting spring 1, so as to realize to cutting force size control
System, and then protect lathe and cutter.
The present invention is applied in processing inner hole of workpiece both sides chamfering or the occasion for needing to lathe overload protection.
