Abstract
A novel cutter for machining a boss inner circle and a boss outer circle comprises a cutter body. A first cutting edge, a second cutting edge and a third cutting edge are arranged at one end of the cutter body. The first cutting edge and the second cutting edge share the same rake angle and relief angle and are perpendicular to the axial direction. The distance H between the first cutting edge and the second cutting edge is the same as the height of a machined part boss. The tool cutting edge angle of the third cutting edge is 7 degrees. A fourth cutting edge is further arranged at the front end of the cutter body and used for machining an inner hole. The novel cutter can machine the outer circle, the end face and the inner hole of the boss at the same time. In the process of machining, the outer circle, the inner hole and the end face of the part boss can be finished on the same machine tool through machining. Size and form and location tolerance requirements can be completely met, machining efficiency is improved, product quality is guaranteed, production cost is reduced, and the functions of the machine tool are expanded.
Description
Technical field
The present invention relates to a kind of cutter, be specifically related to be suitable in one the new-type cutter that housing, casing, cover plate, base body class part boss cylindrical and plane are processed simultaneously.
Background technology
In the production of engineering goods, often have the processing of a large amount of housings, casing, cover plate, base body class part, this type of part is generally cast aluminium, wrought aluminium part, and part has the hole that many places precision is higher, outer circular bosses, plane.For guaranteeing hole, outer circular bosses, planar dimension and form and position tolerance, need on dissimilar lathe, process assurance, the production cycle is long, and working (machining) efficiency is low, and manufacturing cost is high.
Summary of the invention
For prior art middle shell, casing, cover plate, base body class part process as there being position, hole, many places on part, boss and end face cause the problem that working (machining) efficiency is low, the production cycle is long with one heart, provide a kind of and can on machine tool, by clamped one time, can complete above processing content simultaneously, realize high efficiency, high-quality, low-cost processing.
The object of the present invention is achieved like this: a kind of new-type cutter of processing boss inside and outside circle, comprise cutter hub, and one end of cutter hub is provided with the first cutting edge, the second cutting edge and the 3rd cutting edge.
The first cutting edge, the second cutting edge are same anterior angle and relief angle, with axially vertical.
The first cutting edge is identical with part to be processed boss height with the spacing H of the second cutting edge.
The tool cutting edge angle a of the 3rd cutting edge is 7 degree.
The new-type cutter of processing boss inside and outside circle provided by the invention can be processed boss cylindrical, end face, endoporus simultaneously; Add and part boss cylindrical, endoporus, end face machining all can be completed on same lathe man-hour.Can meet size and Geometrical Tolerance Principle completely, improve working (machining) efficiency, guarantee product quality, reduce production cost, and expanded lathe function.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is left view of the present invention.
The specific embodiment
Structure of the present invention is as described in Fig. 1 and 2, and a kind of new-type cutter of processing boss inside and outside circle, comprises cutter hub 5, and one end of cutter hub 5 is provided with the first cutting edge 1, the second cutting edge 2 and the 3rd cutting edge 3.First cut sword 1, the second cutting edge 2 is same anterior angle and relief angle, with axially vertical.The first cutting edge 1 is identical with part to be processed boss height with the spacing H of the second cutting edge 2.The tool cutting edge angle a of the 3rd cutting edge 3 is 7 degree.Cutter hub 5 front ends are also provided with for processing the 4th cutting edge 4 of endoporus.
The present invention utilizes Common boring cutter to change a social system.The first cutting edge 1, the second cutting edge 2 and the 3rd cutting edge 3 guarantee angle and the depth of parallelism by grinding, and the 4th cutting edge 4 passes through grinding-shaping.The anterior angle of each cutting edge, relief angle after grinding according to processing parts actual needs grinding-shaping.Utilize the first cutting edge 1, the second cutting edge 2 and the 3rd cutting edge 3 can process boss cylindrical and end face simultaneously, utilize the 4th cutting edge 4 can process endoporus.
Operation principle of the present invention is as follows: after processed part and this cutter clamping, start lathe, when tool rotating shaft is to when motion, the first cutting edge 1, the second cutting edge 2 cut simultaneously, the 3rd cutting edge 3 by cutter moving radially on cutter head realize and control boss excircle dimension, tool cutting edge angle α is 7 degree.On cutter hub 5, also can grind the 4th cutting edge 4 for processing endoporus, solved the problem that housing, casing, cover plate, base body class part are processed boss cylindrical, end face, endoporus simultaneously, this type of part boss cylindrical, endoporus, end face machining all can have been completed on same lathe.Through the processing experiment of part repeatedly, meet size and Geometrical Tolerance Principle completely, improved working (machining) efficiency, guaranteed product quality, reduce production cost, and expanded lathe function.
