Description
Technical field
The present invention relates to the technical field of machining instrument, and in particular to a kind of internal bore groove cutting element.
Background technology
Internal bore groove cutting element is indispensable important tool in hole machined.Removable blade is fixed by screws in
Become cutter on handle of a knife.As the popularization of carbide blade is used, how to allow blade extend longer from cutter head side
Clamping becomes more and more urgent.Cutter head needs to stretch into endoporus depths and goes to cut a groove, and the retained part of cutter head receives endoporus and row
The restriction cut again can not be too big, and then the mode using trip bolt and elastic groove clamping is very universal in the prior art.
The JP2016-64466A of Japanese capital Co., Ltd. discloses a kind of monoblock type inner hole groove cutting element, by handle of a knife
Head does L-shaped, and will process compressed gap in the middle of L-shaped head, and the straight portion's processing screw hole of L-shaped is clamped with screw fastening；L-shaped is horizontal
Extension clamps interchangeable blade as with the compressed gap separate holder 9 with maxillary 15 and lower jaw 17 in holder 9.
This is the typical way that trip bolt coordinates that elastic groove is clamped, and is clamped by the screw hole 27 on cutter head main shaft, determines that L-shaped is horizontal
Can not extend far to the maxillary and lower jaw of extension, otherwise clamping torque loss is very big, it is impossible to reliable grip.
How to develop a kind of internal bore groove cutting element, not against screw can reliable retention interchangeable blade, blade can also
Extend laterally very long, become a general character difficult problem for industry development.
The content of the invention
For defect present in above-mentioned prior art, it is an object of the invention to provide a kind of internal bore groove cutting element.
The object of the present invention is achieved like this, a kind of internal bore groove cutting element, including handle of a knife and L-shaped cutter head, L-shaped cutter head

And be pressed in the compression power transmission portion.
Further, blade assembly includes lower clamping pad, upper cliping pad and blade, stack fin blades upper cliping pad and lower clamping pad it
Between, upper cliping pad top clamps face and is clamped in described holding out against on inclined-plane with inclined-plane, upper pad is held out against.
Further, the clamping hole slot also includes side block wall, and the side block wall also horizontally outward extends with bottom jaw, but side
Retaining wall front end 3-10mm shorter than the bottom jaw.
Further, lower clamping pad is provided with apical tooth, and upper cliping pad bottom surface rear portion is provided with adjustment teeth groove, and apical tooth abuts to adjustment teeth groove
In.
Further, with face is leaned, the face of leaning is provided with abutting part to lower clamping pad, and the abutting part includes abutting hole, abuts
In hole, threaded engagement has abutting post, abuts post and has bearing surface, and the bearing surface is with the trailing flank identical with the blade
Gradient, in interlocking pattern, the bearing surface is connected on the trailing flank of blade.
Further, the C rings clamp system is made up of spring steel.
Further, bottom jaw is from cylindrical body portion outer surface horizontally outward extended distance LSupportMeet
Wherein, RPostFor the radius in cylindrical body portion.
Further, push up jaw be arranged in cylindrical body portion, with bottom jaw angle (α) at 5 °～20 ° from cylindrical body portion
Axle center extends radially outwardly.
Further, bottom jaw extends horizontally into cylindrical body portion from lateral extensions, into the length in cylindrical body portion
More than the radius R in cylindrical body portionPost。
The internal bore groove cutting element, in order to solve " not against screw can reliable retention interchangeable blade, blade can also be horizontal
To extend it is very long " technical barrier, by following technological means：
(1) overall L-shaped cutter head 2 opens up clamping hole slot 3, there is provided horizontal base jaw and inclination maxillary
Such design had both maintained the globality of retaining part and handle of a knife, also provides for holding function and horizontally outward prolongs
The bottom jaw stretched, the clamping for blade provide horizontal support with handle of a knife one, while provide that maxillary is inclined, for blade assembly
Insertion.
(2) C rings clamp system
The upper pad of C ring clamp systems clamps face and is clamped in the holding out against on inclined-plane of clamp pad, is blade assembly press-in clamping
Lasting clamping force is provided in hole slot 3.
Overall L-shaped cutter head 2 opens up clamping hole slot 3 for clamping the horizontal base jaw provided with handle of a knife one, C ring clamp systems
For providing coupling mechanism force in toolbox press-in hole slot, therefore the two has mutual synergism.
The internal bore groove cutting element, had both designed the horizontal base jaw overall with handle of a knife and had inclined maxillary, while and designing
Matching C rings clamp system provides coupling mechanism force, has the globality of cutter holding concurrently, provides not for interchangeable blade again
The lasting chuck(ing) capacity of bolt is suitable for, versatility and the holding capability of endoporus cutting element is substantially increased.
