Cutter head applies the compression spring of vertical direction active force, and the bottom of cutter head is blade, at the top of cam radius maximum and cutter head
During contact, blade is fully extended in outside cutter hub；When at cam radius minimum with cutter head top contact, compression spring makes blade contract
Return in cutter hub.
It is preferred that cam shaft distal passes through screw drive cam from one end of handwheel.
It is preferred that handwheel passes through screw drive camshaft.
It is preferred that being provided with a series of positioning holes perpendicular to handwheel end face on handwheel, cam half is corresponded to respectively
At footpath maximum, cam radius minimum and centre position hole uniform therebetween, an alignment pin is horizontally inserted extremely in positioning hole
Inside cutter hub.
It is preferred that cutter hub inner cam axle lower horizontal sets cutting fluid runner, cutting fluid runner is close to cutter head
One end be provided with face cutter head blade cutting fluid spout.
It is preferred that bushing is provided between cutter head and cutter hub.
Operation principle of the present utility model is as follows：Handwheel is rotated, handwheel drives camshaft rotation, and camshaft band moving cam revolves
Turn, when cam radius maximum and cutter head top contact, blade is fully extended in outside cutter hub；At cam radius minimum and knife
When overhead contacts, compression spring makes blade retract in cutter hub.When blade is wholly or partly stretched out in outside cutter hub, can complete
Deep hole boring or deep hole grooving.When blade is received into cutter hub completely, cutter can in part deep-hole freedom of movement, and reach treat
Working position.Rotate and be provided with a series of positioning holes on handwheel to adjust the rotary state of cam so that cutter head is in difference
Radial direction operating position, alignment pin is inserted into positioning hole when turning to the position of needs, realizes cutter head operating position really
Fixed, cutting fluid runner can be connected with high-pressure coolant pipe, cutting fluid into after cutting fluid runner from cutting fluid nozzle exit area high pressure
Spray, and directly act on cutter head (cutwork position).This solves deep-hole boring cutter by physical dimension limits, no
Can be set coolant fill orifice to cool down cutter in knife bar main body the problem of, for cutter without phenomenon of rupture, Product Precision is good,
It is highly polished, high yield rate.
The beneficial effects of the utility model are：Not only can bore hole but also can grooving, work cutter head conversion is convenient, without withdrawing
Cutter head is changed, work efficiency greatly improves；Knife bar main body radial dimension can increase as far as possible, and it is small, strong thoroughly to solve cutter radial size
The problem of low is spent, cutter is not easy to break；Knife bar main body radial dimension can set up cutting fluid feed path after increasing, and solve cutter
The problem of cooling；Yield rate improves, and reduces production cost；Substantially increase machining accuracy and machined surface finish；Cutter makes
With life to original 3 times.

Embodiment
Illustrate embodiment of the present utility model below by way of specific instantiation, those skilled in the art can be by this theory
Content disclosed by bright book understands other advantages and effect of the present utility model easily.The utility model can also be by addition
Different embodiments are embodied or practiced, and the various details in this specification can also be based on different viewpoints with answering
With, without departing from it is of the present utility model spirit under carry out various modifications or alterations.
The cutter of a kind of deep hole processing and deep-hole slot, including cutter hub 6, the handwheel 4 positioned at the side of cutter hub 6, handwheel 4 pass through spiral shell
The position that the camshaft 7 set positioned at the inner horizontal of cutter hub 6 of line driving, the one end of camshaft 7 away from handwheel pass through screw drive
Cam 8 inside cutter hub, the lower end of cam 8 is in close contact the top of the cutter head 1 of vertical direction motion, inside the lower end of cutter head 1
Provided with spring groove, the compression spring 10 for applying vertical direction active force to cutter head is provided with inside spring groove, the bottom of cutter head 1 is knife
Piece 11, when the radius maximum of cam 8 and 1 top contact of cutter head, blade 11 is fully extended in outside cutter hub 6；When cam radius most
When small place is with 1 top contact of cutter head, compression spring 10 makes blade 11 retract in cutter hub 6.Do not take up space, more conducively reduce cutter hub
Size.When blade is wholly or partly stretched out in outside cutter hub, deep hole boring or deep hole grooving can be completed.Blade is received into knife completely
When internal, boring cutter can in part deep-hole freedom of movement, and reach position to be processed.
A series of positioning holes 12 perpendicular to the end face of handwheel 4 are provided with handwheel, correspond to cam radius maximum, convex respectively
The minimum place of radius and uniform centre position hole therebetween are taken turns, is horizontally inserted in positioning hole inside an alignment pin 5 to cutter hub 6.
The lower horizontal of 6 inner cam axle of cutter hub 7 sets cutting fluid runner 3, and cutting fluid runner 3 is provided with close to one end of cutter head
The cutting fluid spout 2 of face cutter head blade.
Bushing 9 is provided between cutter head 1 and cutter hub 6.Bushing is fixed on cutter hub using soket head cap screw, easy to disassemble and more
Tool changing head, play a part of retaining spring, be cutter head motion guide (making cutter head to be moved up and down along busing axis).
When blade is wholly or partly stretched out in outside cutter hub, deep hole boring or deep hole grooving can be completed.Blade is received into completely
When in cutter hub, boring cutter can in part deep-hole freedom of movement, and reach position to be processed.Stretched principle using cutter head, knife bar master
Body radial dimension can increase as far as possible, even if being enlarged to 0.1mm smaller than hole degree, can equally complete the work of boring deep hole and grooving
Make, thoroughly solve the problems, such as that cutter radial size is small, low intensity.
The course of work of the present embodiment is as follows：Handwheel is rotated, handwheel drives camshaft rotation, and camshaft band moving cam revolves
Turn, when cam radius maximum and 1 top contact of cutter head, blade 11 is fully extended in outside cutter hub 6；At cam radius minimum
During with 1 top contact of cutter head, compression spring 10 makes blade 11 retract in cutter hub 6.Rotate and be provided with a series of positioning on handwheel
Hole is adjusting the rotary state of cam so that cutter head is in different radial direction operating positions, when turning to the position of needs
