Problems solved by technology

[0004] 1) The connection between the existing indexable arc thread milling cutter blade and the mounting part is single, and the connection is not firm enough, which leads to loosening of the blade during use and affects the milling accuracy;
[0005] The existing indexable arc thread milling cutter insert and the mounting part are only connected by bolts, which cannot guarantee that the insert will not shift during milling, and the existing insert blade is easy to wear, which increases the cost of use

Abstract

The invention discloses an indexable arc thread milling cutter based on an aero-engine. The indexable arc thread milling cutter comprises a milling cutter body and a blade. The blade fixing device has the beneficial effects that the first threaded hole, the second threaded hole and the fastening bolt are arranged, the blade can be fixedly mounted in the mounting part through the matching effect of the first threaded hole, the second threaded hole and the fastening bolt, and it can be guaranteed that the position of the blade cannot be changed during use through the matching effect of the limiting block and the limiting hole; the milling quality is further improved; through the arrangement of the sliding groove, the sliding block, the movable block and the compression spring, when the blade is installed, connection between the blade and the installation part can be firmer through the elastic force effect of the compression spring, the three cutting edges are evenly arranged on the outer side of the blade, the surface of each cutting edge is provided with the hard coating, and when the blade is used, the blade is not prone to falling off. When one cutting edge is seriously abraded, the two cutting edges can be utilized through transposition, and the use cost is reduced.

Description

technical field [0001] The invention relates to a thread milling cutter, in particular to an indexable circular arc thread milling cutter based on an aero-engine, and belongs to the technical field of milling cutters. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling. When working, each knife tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. Among them, indexable arc thread milling cutters are widely used and are often used in the field of aero-engine manufacturing. [0003] However, existing indexing arc thread milling cutters have some problems in use: [0004] 1) The connection between the existing indexable arc thread milling cutter blade and the mounting part is single, and the connection is not firm enough, which leads to loosening of the blade during use and affects the ...
