Abstract

The invention relates to a whirlwind milling device. The whirlwind milling device consists of a milling body, a base and a motor, wherein a high-speed rotating cutter is arranged in the milling body and consists of at least six forming tools; a main shaft is arranged in the milling body; a chuck is arranged on the main shaft; a first rotary shaft is arranged at one end of the milling body; the periphery of the first rotary shaft is wrapped in a belt; a second rotary shaft is arranged at one end of the motor; the high-speed rotating cutter drives the rotary shafts to move at high speed through a belt on the motor; the rotating axis of the high-speed rotating cutter is inclined at a helix lead angle relative to the axis of a workpiece. By the adoption of the structure, the machining efficiency is high, and compared with the conventional processing efficiency, the processing efficiency can be improved by over 10 times; a product is formed by one-time tool operation, and eccentric cutting without tool retraction is achieved, so that the accuracy is high; a whirlwind mill made through modification of a lathe does not change the structure of the lathe, the helix lead angle is adjustable, and the device is convenient to mount; the investment cost for special equipment is reduced; the surface roughness can reach Ra0.8 micron, and the processing accuracy is improved by 2 levels; the axial feed speed of the lathe is low, so that the lathe is easy to operate, and the requirement on the professional skill of a worker can be reduced.

Description

technical field [0001] The present invention relates to a milling equipment, in particular to a milling device for milling threads. Background technique [0002] At present, whirlwind milling is a high-speed milling thread matching with ordinary lathes. It uses a cemented carbide forming knife mounted on a high-speed rotating cutter head to mill out threads from the workpiece. During the machining process, the cutting spatter is like a whirlwind, so it is named—whirlwind milling. The precision of the traditional milling device is not high, and the whirlwind milling transformed from the lathe changes the structure of the lathe, the helix angle cannot be adjusted, and the installation is inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a milling device with high precision, adjustable helix angle and high metal cutting rate. [0004] In order to solve the above-mentioned technical problems, the presen...
