Description

A kind of internal bore groove cutting element
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.Replaceable blade is fixed by screws in Become cutter on handle of a knife.Used with the popularization of carbide chip, how to allow blade to extend sideways from cutter head longer Clamping becomes more and more urgent.Cutter head needs to stretch into endoporus depths and removes one groove of cutting, and the retained part of cutter head is by endoporus and row The limitation cut again cannot be too big, and the mode then clamped using trip bolt and elastic groove 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 is done L-shaped, and processing compressed gap among L-shaped head, the straight portion's processing screw hole of L-shaped is fastened with screw and clamped；L-shaped is horizontal Extension clamps interchangeable blade as with the compressed gap separated clamping piece with maxilla and lower jaw in clamping piece.This is tight Gu the typical way that screw fit elastic groove clamps, clamps by the screw hole on cutter head main shaft, determines L-shaped lateral extensions Maxilla and lower jaw cannot extend far, otherwise clamping torque loss it 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 the general character problem of industry development.
The content of the invention
For above-mentioned defect existing in the 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 With handle of a knife integrally connected, L-shaped cutter head includes integrally formed cylindrical body portion and lateral extensions；The L-shaped cutter head is equipped with folder Hold hole slot；The clamping hole slot includes bottom jaw and top jaw；Blade assembly is clamped between bottom jaw and top jaw；
C ring clamp systems are further included, C ring clamp systems are set in cylindrical body portion, and C rings clamp system includes clamping Groove, clamping slot has upper pad clamping face and lower jaw clamps face, when C ring clamp systems are set in L-shaped cutter head and are in interlocking pattern, institute Lower jaw is stated to clamp on the bottom surface for the lateral extensions that face is connected to L-shaped cutter head；Upper pad clamping face is clamped on toolbox, is knife Tool component provides the clamping force being pressed into clamping hole slot.
Further, the C rings clamp system further includes ring portion body, compresses power transmission portion and clamping sleeve, the clamping slot It is arranged on ring portion body, compression power transmission portion is fixedly connected with ring portion body or integrally connected, and clamping sleeve threaded engagement is in handle of a knife And it is 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, which has, holds out against inclined-plane, and upper pad clamping face is clamped in described hold out against on inclined-plane.
Further, the clamping hole slot further includes side block wall, and the side block wall also horizontally outward extends with bottom jaw, but side Retaining wall front end is shorter 3-10mm than the bottom jaw.
Further, lower clamping pad is equipped with apical tooth, and upper cliping pad bottom surface rear portion is equipped with adjustment teeth groove, and apical tooth abuts to adjustment teeth groove In.
Further, lower clamping pad, which has, abuts against face, and the face that abuts against is equipped with abutting part, and the abutting part includes abutting hole, abuts Threaded engagement has abutting column in hole, and abutting column has bearing surface, and the bearing surface has identical with the trailing flank of 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 of spring steel.
Further, bottom jaw is from cylindrical body portion outer surface horizontally outward extended distance LSupportMeet Wherein, RColumn isThe radius in cylindrical body portion.
Further, top jaw is 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 portionColumn。
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, pass through following technological means：
1) overall L-shaped cutter head 2 opens up clamping hole slot 3, there is provided horizontal base jaw and inclination maxilla
Such design had both maintained the globality of retaining part and handle of a knife, also provided horizontal direction extension for clamping function The bottom jaw stretched, horizontal support with handle of a knife one is provided for the clamping of blade, while provides inclination maxilla, for blade assembly Insertion.
2) C rings clamp system
The upper pads of C ring clamp systems clamps face and is clamped in the holding out against on inclined-plane of clamp pad, for 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 to clamp the horizontal base jaw provided with handle of a knife one, C ring clamp systems It is pressed into for toolbox in hole slot and provides coupling mechanism force, therefore the two is with mutual synergistic effect.
The internal bore groove cutting element, had not only designed and the horizontal base jaw of handle of a knife entirety and had tilted maxilla, but also designed Matching C ring clamp systems provide coupling mechanism force, have the globality of cutter holding concurrently, and provide not for interchangeable blade The lasting chuck(ing) capacity of bolt is applicable in, substantially increases the versatility and holding capability of endoporus cutting element.
