T-shaped slot milling cutter for aero-engine

Abstract

The invention discloses a T-shaped slot milling cutter for an aero-engine. The T-shaped slot milling cutter comprises a milling cutter head, milling cutter edges, a chip removal slot, a connecting fixing ring, fixing insertion columns, a milling cutter column handle, clamping threads, a damping transition block, a supporting inner column, filling layers, protective coatings, a T-shaped fixing insertion column and a milling cutter T-shaped slot. The T-shaped slot milling cutter for the aero-engine has the beneficial effects that the multiple milling cutter edges form a group and are fixed around the edge of the milling cutter head, the T-shaped fixing insertion column at the top end of the milling cutter column handle and the milling cutter T-shaped slot in the milling cutter head are fixedin an insertable mode, and every two fixing insertion columns form a group and mirror images are symmetrically arranged. The fixing insertion columns penetrate through a body of the connecting fixingring and are fixedly connected with the internal milling cutter column handle of the connecting fixing ring, and the multiple clamping threads form a set and are parallelly fixed to the outer wall ofthe bottom end of the milling cutter column handle. The protective coatings are anti-corrosion metal coatings, the protective coatings and the anti-corrosion metal coatings are arranged on the outerwall of the milling cutter column handle, the damping transition block is a tough metal column and arranged in the top end of the milling cutter column handle, so that vibration is reduced, and the bearing capacity is increased.

Description

Technical field[0001]The invention relates to a device, in particular to a T-slot milling cutter used on an aero engine, belonging to the technical field of cutting tools.Background technique[0002]A milling cutter is a rotary tool with one or more teeth used for milling. When working, each cutter tooth intermittently cuts off the margin of the workpiece. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. At present, most milling cutters are made of cemented carbide materials, which have the advantages of strong cutting ability and corrosion resistance.[0003]There are many types of T-slot milling cutters currently on the market. However, there are still some problems in actual use. First, most of the existing T-slot milling cutters cannot perform high-speed and precise cutting on the surface. It is easy to cause damage to the edge of the milling cutter during the process. Second, most of the existing ...

AI Technical Summary

Problems solved by technology

[0003] There are many kinds of T-slot milling cutters on the market now, but there are still some problems in the actual use process. First, most of the existing T-slot milling cutters cannot perform high-speed and precise cutting on the surface. In the process, it is easy to cause damage to the edge of the milling cutter. Second, most of the existing T-slot milling cutters cannot fix the cutter head very well. When the cutter head needs to be replaced during the operation, it cannot be replaced in time, resulting in a decrease in work efficiency. Low, thirdly, most of the existing T-slot milling cutters do not have a good structure, and there are deficiencies in the clamping, shock absorption and corrosion resistance of the shank
