Abstract
The present invention provides an improved structure of a wood working milling cutter. The circumference of a circular cutter head is provided with a plurality of semicircular embedding grooves for a plurality of cutter handles with the same circular arc to be embedded, the intermediate section of the arc surface at the top side of each semicircular embedding groove is provided with a semicircular screw hole, the bottom end of each cutter handle is combined with a cutter blade, and the intermediate section of the arc surface at the top side of each cutter handle corresponding to the position of a semicircular hole of the cutter head is provided with a semicircular hole with an inwards convex ring flange to cause the semicircular screw hole and the semicircular hole to be combined into a circular concave hole for containing a fine adjustment screw bolt of which the intermediate section is provided with a concave ring groove to extend; the ring flange of the semicircular hole is clamped in the concave ring groove of the fine adjustment screw bolt to form a clamping stopper, and the screw thread part of the fine adjustment screw bolt is screwed with the semicircular screw hole on each semicircular embedding groove of the cutter head. The lifting position of each cutter handle can be adjusted by the positive rotation and the inverse rotation of the fine adjustment screw bolt, then a fixed screw bolt penetrates a preset long hole on each cutter handle, and screws in a fixed screw hole corresponding to the intermediate section of each semicircular embedding groove to realize positioning, and thus, the functions of the lifting adjustment and the position of the cutter blade are achieved.
Description
Technical field
The present invention relates to a kind of carpenter's machining tool, particularly a kind of improved structure of carpenter's milling cutter is meant that especially a kind of simple structure, milling cutter just adjust the fixing firm dependency structure of facility, precision and milling cutter.
Background technology
Common relevant milling cutter construction, " the light-duty milling cutter of high rigidity " as the novel No. 165938 patent case of TaiWan, China (application number is No. 87211729), it mainly comprises: parts such as cutter head and cassette tool rest, wherein cutter head central authorities establish a class hole of running through, in order to be fixed in the main shaft of milling machine, and the cassette tool rest is established an appearance tool rest, can be for the blade locking; It is characterized in that, the circumferential surface of this cutter head is provided with many storage tanks, can stretch into for the cassette tool rest, be provided with the fine setting screw that radially extends and be axially-aligned towards the center in this storage tank, fixing threaded hole and positioning screw hole, this cassette tool rest is established one and is radially run through and be oblong long perforation, pass through and be fixed at fixing threaded hole for a fixed screw, this corresponding fine setting in length perforation top screwhole position is established the perforation of a circle, at the cross-sectional trimming groove in the perforation corresponding surface position of cassette tool rest, a non-long blind hole that runs through and be long ellipse shape is established in this length perforation vertically below, and this long blind hole position is corresponding to positioning screw hole; The threaded portion of one fine adjustment screw is the fine setting screw that is active in cutter head, the end in addition of its threaded portion is established a pilot pin, and accurately locate in the positioning pilot hole of ccontaining accent screw front end, an end of this pilot pin extends the pod head of an eccentric position, and this pod head is to be placed in the trimming groove of cassette tool rest; One location bolt is fixed in the positioning screw hole of cutter head, the pod head of its tool one precise measure, this pod head part is placed in the positioning pilot hole, and part extends outside the positioning pilot hole, and supply the long blind hole correspondence of cassette tool rest to hold to go into, to reach the effect of upper and lower fine setting of cassette tool rest and location.
In the said structure, it is owing to be when utilizing pilot pin to rotate, the pod head of its eccentric combination can produce the displacement of off center, move and drive the cassette tool rest, the cassette tool rest then can form guiding by the pod head of long blind hole fit bolt, makes this cassette tool rest form the adjustment of upper and lower position; Yet, this kind structure, it has following shortcoming when using:
(1) stroke adjusted of this cassette tool rest liftable is subject to the eccentric distance that combines between pod head and pilot pin, and its adjustable scope is minimum, is difficult to realistic demands of applications.
(2) this cassette tool rest is when assembling, must be screwed into fine adjustment screw and bolt in the cutter head respectively in advance, and then with the trimming groove of cassette tool rest and corresponding respectively pod head and the bolt outer end that is sleeved on fine adjustment screw of long blind hole, very inconvenient on it is assembled.
(3) this cassette tool rest is fixing, and rely on this fixed screw fully and run through long perforation and locate, yet, when cutter head running and each blade cut machined object, can produce vibration and active force greatly, only rely on the packing location of single fixed screw, very easily produce the situation that gets loose.
Because common milling cutter construction has above-mentioned shortcoming, the inventor studies and improves at these shortcomings.
Summary of the invention
The present invention aims to provide a kind of improved structure of carpenter's milling cutter, it mainly is that cutter head periphery in circle is provided with many semicircle caulking grooves, embed for a plurality of handle of a knifes with identical circular arc, each semicircle caulking groove is provided with a semicircle screw in cambered surface stage casing, top side, and the bottom of this handle of a knife is combined with a blade, and its cambered surface stage casing, top side is provided with the semicircle hole of a tool internal projecting ring flange corresponding to aforementioned semicircle screw, make this semicircle screw and semicircle hole knot form a circle shrinkage pool, can stretch into for the trimming bolt that a ccontaining stage casing is provided with concave ring groove, be embedded in the concave ring groove in the trimming bolt with the ring flange in this semicircle hole and form stopper, the threaded portion of trimming bolt then with the semicircle screwhole spiro bonding of other side, utilize the positive and negative rotation of this trimming bolt, and can adjust the lifting position of handle of a knife, run through on the handle of a knife default slotted hole with set bolt then and be screwed into and make it the location in the fixing threaded hole in semicircle caulking groove stage casing, use and reach long lifting fine setting effect apart from blade, this is a main purpose of the present invention.
According to this kind improved structure of carpenter's milling cutter of the present invention, it can a plurality of set bolts runs through handle of a knife and is screwed in the semicircle caulking groove of cutter head, and reaches more firm locating effect, and it has simple structure, assembles characteristics easily, and this is an another object of the present invention.
As for detailed construction of the present invention, application principle, effect and effect, then can be understood completely with reference to the following explanation of being done with reference to the accompanying drawings.
