Abstract
The utility model discloses a milling cutter which comprises a cylindrical cutter body, wherein the rear end of the cutter body is connected with a cutter handle, at least two cutter heads are distributed on the cutter body, and the cutter heads comprise four cutting portions which encircle the cutter body. Each cutting portion comprises a side cutting edge and bottom cutting edges located on two sides of the side cutting edge, active faces of the four side cutting edges are in an arc shape, and scrap discharge grooves are arranged between adjacent cutting portions. The milling cutter can carry out machining on a plurality of semi-circle grooves at the same time, and is high in machining efficiency and accuracy.
Description
Technical field
The utility model relates to a kind of milling cutter, particularly a kind ofly processes the milling cutter that half slot is used.
Background technology
The metal connector of using in the refrigeration plant on the automobile mostly is the pipe fitting 7 of some semicircle tubulars, as shown in Figure 1, is enclosed within outside the refrigerator pipes, and pipe inside can be split into several independently cavitys, so just need to be carved with half slot 8 at the inwall of pipe, is used for cutting apart pipe fitting.This half slot all is to adopt T-shaped milling cutter work in-process to process in the heart to make at present, the groove bottom ratio of precision of the half slot of traditional T-shaped milling cutter processing is higher, but the both sides precision of groove is inadequate, and this T-shaped milling cutter can only be processed a half slot at every turn, if on the pipe fitting a plurality of half slots are arranged, can only position respectively, successively milling, will affect like this efficient of processing, and the distance between each half slot is not easy control, deviation easily occurs, affect the quality of whole product.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of milling cutter, can process simultaneously a plurality of half slots to reach, and improves working (machining) efficiency, and can guarantee the purpose of the quality of processing.
For achieving the above object, the technical solution of the utility model is as follows: a kind of milling cutter, comprise cylindric cutter hub, described cutter hub rear end is connected with handle of a knife, be distributed with at least 2 cutter heads on the described cutter hub, described cutter head comprises 4 cutting portions that are surrounded on the cutter hub, and described cutting portion comprises the cutting side edge and is positioned at the cutting shear blade of described cutting side edge both sides, the sword face of described 4 cutting side edges is circular arc, between the adjacent cutting portion chip area is arranged.
Preferably, described cutter head comprises 3, is uniformly distributed on the described cutter hub.
Preferably, described handle of a knife is cylindric, and described handle of a knife and described cutter hub coaxial line.
By technique scheme, be distributed with a plurality of cutter heads on the cutter hub of the milling cutter that the utility model provides, can carry out simultaneously the processing of a plurality of half slots, be conducive to improve the efficient of processing; Cutting portion comprises cutting side edge and cutting shear blade, can guarantee the precision of half slot bottom surface, can guarantee again the precision of two sides of half slot.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art.

The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
The utility model provides a kind of milling cutter, structural representation as shown in Figure 1, and this milling cutter can carry out the processing of a plurality of half slots simultaneously, and working (machining) efficiency is high, and machining accuracy is high.
Described milling cutter comprises cylindric cutter hub 1, and cutter hub 1 rear end is connected with handle of a knife 2, is distributed with at least 2 cutter heads 3 on the cutter hub 1; Cutter head 3 comprises 4 cutting portions that are surrounded on the cutter hub 1, and cutting portion comprises cutting side edge 4 and the cutting shear blade 5 that is positioned at cutting side edge 4 both sides, and cutting side edge 4 is used for the bottom of milling half slot 8, and cutting shear blade 5 is for two sides of milling half slot 8; The sword faces of 4 cutting side edges 4 are circular arc, can guarantee the radian of the half slot 8 processed; Chip area 6 is arranged between the adjacent cutting portion, and chip area 6 can in time be discharged the waste material that milling is got off, and prevents blocking of waste materials cutter head 3, impact processing.
In the present embodiment, cutter head 3 comprises 3, is uniformly distributed on the cutter hub 1, and the quantity of cutter head 3 and the position of cutter head 3 on cutter hub 1 can be adjusted according to the needs of product.
Handle of a knife 2 is cylindric, and handle of a knife 2 and cutter hub 1 coaxial line, add man-hour, with cutter hub 1 horizontal positioned, handle of a knife 2 is fixed in the rotating shaft, product passes through the anchor clamps fixed placement in the side of cutter hub 1, after the location, can start rotating shaft, cutter hub 1 rotation, cutting portion can mill out the shape that needs at product, and cutting side edge 4 and cutting shear blade 5 can guarantee respectively the machining accuracy of bottom surface and the side of half slot 8.
Be distributed with a plurality of cutter heads on the cutter hub of the milling cutter that the utility model provides, can carry out simultaneously the processing of a plurality of half slots, be conducive to improve the efficient of processing; Cutting portion comprises cutting side edge and cutting shear blade, can guarantee the precision of half slot bottom surface, can guarantee again the precision of two sides of half slot.
In addition, the quantity of cutter head and the distance between the cutter head can change according to the requirement of product, have satisfied the multiple requirement of the product of processing, make the scope of application of cutter more extensive.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, in other embodiments realization.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
