Abstract
Description
Technical Field
[0001] The utility model relates to a gear processing tool, in particular to a double-cut small-module indexable gear milling cutter. Background Art
[0002] At present, the gear milling of gear milling machines belongs to heavy-duty forming processing. The power of the machine tool is relatively large, and it processes one tooth at a time. The module of the processing is generally large, between M8 and M25. However, for small-module gear workpieces with a module below M6, the processing efficiency of traditional gear milling machines seems to be "a big horse pulling a small cart". The power of the machine tool is wasted and the processing time is long. Due to the large batch size of products and the short construction period, and due to program reasons, adjacent teeth need to be processed at the same time, and cross-tooth processing is not allowed. The traditional double-cut form is limited by the tooth pitch and needs to be processed across teeth. Therefore, it is urgent to develop an efficient small-module double-cut milling cutter to solve the above problems, so that two adjacent tooth grooves can be processed at the same time in the same time. Since the power of the machine tool is sufficient, the efficiency can be doubled. Utility Model Content
[0003] The utility model provides a double-cut small-module indexable gear milling cutter to solve the problem that a traditional small-module indexable gear milling cutter can only mill one tooth groove in one pass, and the traditional double-cut form requires cross-tooth processing. Due to the limitation of the machine tool program, only adjacent teeth can be processed at the same time. The technical solution to this problem is as follows:
[0004] The utility model discloses a double-cut small-module indexable gear milling cutter, which is composed of a cutter body, an indexable carbide double-cut blade and a blade clamping screw. The cutter body is an integral disc-shaped structure. An indexable carbide double-cut blade groove is arranged at the outer diameter of the cutter body. The indexable carbide double-cut blade is in a shuttle shape, with sharp points on both sides and a flat middle. The sharp parts on both sides of the indexable carbide double-cut blade are used to process tooth grooves, and the middle rectangular part is used for positioning. The indexable carbide double-cut blade grooves are evenly staggered on both sides of the cutter body. The indexable carbide double-cut blade is fixed in the indexable carbide double-cut blade groove through a screw clearance hole by a locking screw. The indexable carbide double-cut blades on both sides constitute the normal tooth profile of the double-cut small-module indexable gear milling cutter.
[0005] The utility model discloses a double-cut small-module indexable gear milling cutter, which is developed by combining indexable gear tools and cemented carbide technology. The indexable cemented carbide double-cut blade adopts a full-tooth structure, which maintains the advantages of four-position rotation of the traditional blade and maximizes the use of the raw materials of the alloy. The full-tooth blade enables the small-module double-cut structure to be realized. In order to ensure the strength of the screw hole in the traditional overlap form, the blade needs to be made very long, but interference will occur in the middle part when the double-cut structure is made. The double-cut structure of the cutter body is very complicated, and the full-tooth structure is simple, easy and reliable to install, saves materials, is easy to process, convenient to disassemble, and has high processing accuracy. Two adjacent tooth grooves can be processed in one pass, so that the processing and production efficiency of the small-module indexable gear milling cutter is doubled, and the utilization rate of the double-cut small-module indexable gear milling cutter equipment is improved.
