How to use high-precision geometric shape milling cutter processing device

Abstract

The invention provides a high-precision machining device of a milling cutter in a geometrical shape and a using method of the high-precision machining device, and belongs to the technical field of machining. A milling cutter outer sleeve is fixedly connected with a side locating plate, the angle of the milling cutter is changed in a rotating mode through a gear, an axial rotating locating screw is fixed on an upper locating plate, an axial horizontal-moving gap adjustment screw is fixed on the side locating plate, and the whole high-precision machining device is fixed on a wire cutting platform. The high-precision machining device of the milling cutter in the geometrical shape and the using method of the high-precision machining device have the advantages that the high-precision machining device can be used on wire cutting equipment, the milling cutter with a complex blade is manufactured by means of rotation and horizontal-moving feeding, the blade comprises a plurality of machining faces, the cutting edge is of a multiple structure with both arcs and oblique lines, machining technology problems of the complex shapes of cage pockets are solved, cage pockets in all sizes are formed at a time, dimensional tolerance and geometric tolerance of pockets are guaranteed, and quality of bearing cages reaches the advanced level in the world.

Description

technical field [0001] A high-precision geometric shape milling cutter processing device and a use method thereof belong to the technical field of machining. Background technique [0002] World ace bearings SKF, FAG, TIMKEN and other bearings use high-precision copper bearing cages, because the copper material is soft and easily deformed, and the dimensional tolerance of the cage pockets is generally ±0.05mm. It is composed of various shapes such as cone angle, and it is very difficult to process such a pocket, mainly because it is very difficult to process with a milling cutter. Contents of the invention [0003] In view of the defects in the prior art, the present invention provides a high-precision geometric shape milling cutter processing device and its use method to realize the purpose of using wire cutting equipment to manufacture high-precision complex geometric shape cutters and process qualified bearing cage parts. [0004] In order to achieve the above purpose, ...
