Description

Technical Field

[0001] The utility model belongs to the technical field of tool cutting and processing, in particular to an indexable composite chamfering tool for machine tool processing. Background Art

[0002] Chamfering cutters for machining are used in industrial production and processing. They are installed on machining centers to process metal parts. Chamfering cutters are widely used in the field of metal internal processing technology. They are mainly installed on machine tools such as milling machines, drilling machines, planing machines, chamfering machines, and for chamfering edges. This type of tool is not only suitable for chamfering of ordinary machined parts, but also for chamfering and deburring of precision and difficult chamfered parts. For example, in the fields of aviation, military industry, and automobile industry, it is used for processing oil, gas, electric valves, engine cylinders, cylinders, spherical through holes, inner wall holes, etc.

[0003] The existing machining process for chamfering is relatively complicated. During the chamfering process, the cutting edge is easily damaged. Since the cutting edge, the cutter head and the cutter handle are designed as an integrated whole, if the cutting edge is damaged, the cutting tool needs to be replaced as a whole, which is costly and wastes resources. In addition, when cutting certain parts, due to the different shapes of the cutting layer cross-section, the angle between the main cutting edge and the assumed feed motion direction, that is, the main deflection angle, is also different, so different cutting tools are needed, which not only increases the cost, but also makes tool switching more cumbersome, which is not conducive to actual production. Utility Model Content

[0004] The purpose of the utility model is to overcome the above problems existing in the prior art and to provide an indexable composite chamfering tool for machine tool processing, which solves the problem that the cutting tool needs to be replaced as a whole due to damage, thereby causing waste of resources, reduces costs, and enables quick tool switching and can meet the work needs of different chamfering processes without the need to change tools, thereby effectively improving production efficiency.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] An indexable composite chamfering tool for machine tool processing comprises a tool handle and a tool head arranged at the end of the tool handle, wherein the end of the tool head connected to the tool handle is a cylindrical structure, and the end of the tool head away from the tool handle is a truncated cone structure;

[0010] The two transfer cutting parts each include a blade 2 and a screw 2, and the two blades 2 can be fixedly installed in the blade slot 1 and the blade slot 2 respectively by means of the two screws 2;

[0011] The blade edge of the second blade is exposed from the blade head.

[0012] Furthermore, the axes of the cylindrical structure and the truncated cone structure coincide with each other.

[0013] Furthermore, the handle is a cylindrical structure;

[0014] The diameter of the cylindrical structure of the cutter head is greater than the diameter of the cutter handle.

[0015] Furthermore, the fixed cutting part includes a blade 1 and a screw 1, and the blade 1 is fixedly mounted on the outer peripheral surface of the truncated cone structure of the cutter head by means of the screw 1.

[0016] Furthermore, the first chip groove and the second chip groove both extend from the top of the frustum structure on the cutter head to the bottom of the cylindrical structure on the cutter head.

[0035] The cutter head 10 is provided with a first chip groove 40 and a second chip groove 50, and the fixed cutting part 20 is located between the first chip groove 40 and the second chip groove 50;
