Description

Hole milling and thread milling composite cutter

Technical Field

The utility model relates to the technical field of machining of machine tool cutters in a machining process, in particular to a hole milling and thread milling composite cutter.

Background

With the rapid development of science and technology and the continuous improvement of the technical level of mechanical processing, the component of milling in the field of mechanical processing is becoming more and more important, and other processing modes such as turning, drilling and the like are gradually replaced to a certain extent. A tool is a tool used for cutting machining in machine manufacturing, and is also called a cutting tool. The cutter is used for cutting metal materials, and is mainly used for processing planes, steps, grooves, forming surfaces, cutting workpieces and the like on a milling machine. Precision parts are made by cutting away the workpiece remnants by a tool, in which process the tool is in direct contact and rubs against the part surface and wears continuously until it is scrapped. The types of the cutters are more, and the cutters can be divided into an integral type, a welding type, a mechanical clamping type and a special type according to the structure of the cutters; the cutting tools can be divided into high-speed steel cutting tools, hard alloy cutting tools, diamond cutting tools and cutting tools made of other materials according to the materials used for manufacturing the cutting tools; according to the cutting process, the cutting tool can be divided into a turning tool, a drilling tool, a boring tool, a milling tool and the like. At present, the function of the cutter is relatively single, some cutters are only used for milling holes, some cutters are only used for milling threads, and the requirement of modern complex machining cannot be met.

Disclosure of Invention

The utility model mainly aims to solve the defects and provides the hole-milling and thread-milling composite cutter which can meet various requirements and achieve the purpose of milling and processing a cutter in the machining process.

The utility model provides a milling hole mills screw thread compound sword, includes that end tooth cutting edge, all teeth, thread cutting edge, heliciform chip groove, tool bit, handle of a knife and cutting edge support and revolve the boss, and the tool bit setting is in the front portion of handle of a knife, and the parallel spiral of tool bit front portion alternately sets up to the cutting edge and supports and revolve boss and heliciform chip groove, and all teeth and thread cutting edge set gradually support to revolve on the boss at the cutting edge, and the end tooth cutting edge setting is anterior at the tool bit.

Further, the helix angle formed by the cutting edge supporting rotary lug boss and the helical chip removal groove of the hole-milling and thread-milling composite cutter is 15 degrees relative to the central axis.

Further, the thread cutting edge profile angle of the hole-milling thread-milling compound cutter is 55 degrees or 60 degrees.

Further, the peripheral tooth length of the hole-milling and thread-milling composite cutter is larger than the thread pitch of the thread cutting edge.

Furthermore, the thread cutting edge of the hole milling and thread milling composite cutter adopts high and low teeth.

Further, the surface of the hole-milling and thread-milling composite cutter is polished, and the roughness is lower than Ra0.3.

Compared with the prior art, the utility model has the beneficial technical effects that: this hole milling thread milling compound cutter simple structure uses convenient operation, can mill the screw thread bottom hole and can fine milling out the screw thread profile again, has satisfied the demand of modern cutter milling process ability, has ensured machining machine tool processingquality, has improved machining machine tool machining efficiency, is fit for using widely.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, the examples of which are set forth merely to illustrate the utility model and are not intended to limit the scope of the utility model.

The utility model provides a hole milling mills screw thread compound sword, supports including end tooth cutting edge 1, all tooth 2, thread cutting edge 3, heliciform chip groove 4, tool bit 5, handle of a knife 6 and cutting edge and revolves boss 7, and tool bit 5 sets up in the front portion of handle of a knife 6, and the parallel spiral in tool bit 5 front portions alternately sets up to the cutting edge and supports and revolve boss 7 and heliciform chip groove 4, and all tooth 2 and thread cutting edge 3 set gradually support revolve boss 7 at the cutting edge on, and end tooth cutting edge 1 sets up in tool bit 5 front portions.

In order to improve the processing effect and the processing quality. The cutting edge of the hole-milling thread-milling composite cutter supports a spiral boss 7 and a spiral chip groove 4 to form a spiral angle of 15 degrees relative to the central axis.

In order to ensure more accurate thread cutting and ensure the processing quality. The thread cutting edge 3 tooth form angle of the hole milling and thread milling composite cutter is 55 degrees and 60 degrees.

In order to increase the tool life, the thread cutting edge adopts high and low teeth. The length of the peripheral teeth 2 of the hole-milling thread-milling composite cutter is larger than the thread pitch of the thread cutting edge 3. Preferably, the thread cutting edge 3 has a high and a low thread.

In order to improve the applicability and meet the use requirement. The surface of the hole-milling and thread-milling composite cutter is polished, and the roughness is lower than Ra0.3.

The compound cutter for milling the holes and the threads can well meet the requirement and also meet the characteristic of diversified structure requirements of cutter products.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
