Abstract
A novel cutting tool processing an inner circle and an outer circle of a boss comprises a cutter body, and one end of the cutter body is provided with a first cutting edge, a second cutting edge and a third cutting edge. The first cutting edge and the second cutting edge are provided with the same front angle and the same back angle, and are perpendicular to the axial direction. A separation distance H between the first cutting edge and the second cutting edge is equal to the height of the boss of a processed part. The main deflection angle alpha of the third cutting edge is 7 degrees. The front end of the cutter body is further provided with a fourth cutting edge used for processing an inner hole. The cutting tool can process the outer circle, an end face and the inner hole of the boss at the same time. During processing, the machining of the outer circle, the internal hole and the end face of the boss of the part can be completed on the same machine tool. Requirements for size and form and location tolerance can be satisfied, processing efficiency is improved, product quality is guaranteed, production cost can be reduced, and functions of the machine tool are expanded.
Description
Technical field
The utility model relates to a kind of cutter, is specifically related to be suitable in one the new-type cutter that housing, casing, cover plate, base body class part boss cylindrical and plane process 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 spare, and part has the higher hole of many places precision, outer circular bosses, plane.For guaranteeing hole, outer circular bosses, planar dimension and form and position tolerance, need to guarantee that the production cycle is long in dissimilar lathe processing, working (machining) efficiency is low, and manufacturing cost is high.
Summary of the invention
For having position, hole, many places, concentric boss and end face to cause the problem that working (machining) efficiency is low, the production cycle is long on prior art middle shell, casing, cover plate, base body class part process such as the part, provide a kind of and can on machine tool, can finish simultaneously above processing content by clamped one time, realize high efficiency, high-quality, low-cost processing.
The purpose of this utility model is achieved in that a kind of new-type cutter of processing the boss inside and outside circle, comprises cutter hub, and an 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 the 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.
Cutter hub 5 front ends also are provided with the 4th cutting edge 4 for the processing endoporus.
The new-type cutter of the processing boss inside and outside circle that the utility model provides can be processed boss cylindrical, end face, endoporus simultaneously; Add and part boss cylindrical, endoporus, end face machining all can be finished at same lathe man-hour.Can satisfy size and Geometrical Tolerance Principle fully, improve working (machining) efficiency, guarantee product quality, reduce production cost, and expanded lathe function.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is left view of the present utility model.
The specific embodiment
Structure of the present utility model is as described in Fig. 1 and 2, and a kind of new-type cutter of processing the boss inside and outside circle comprises cutter hub 5, and an 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 the 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 also are provided with the 4th cutting edge 4 for the processing endoporus.
The utility model 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 simultaneously boss cylindrical and end face, utilize the 4th cutting edge 4 can process endoporus.
Operation principle of the present utility model is as follows: after processed part and this cutter clamping are complete, start lathe, when tool rotating shaft to when motion, the first cutting edge 1, the second cutting edge 2 cut simultaneously, the 3rd cutting edge 3 realizes controlling the boss excircle dimension by cutter moving radially on cutter head, and tool cutting edge angle α is 7 degree.Also can grind the 4th cutting edge 4 on the cutter hub 5 and be used for the 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 finished at same lathe.Through the processing experiment of part repeatedly, satisfy size and Geometrical Tolerance Principle fully, improved working (machining) efficiency, guaranteed product quality, reduce production cost, and expanded lathe function.
