Abstract

The invention provides a machining method and a machining device of a jet nozzle. The machining method of the jet nozzle comprises the following steps that S40, the first end of a first inner conical surface (10) and the first end of an oil jet hole (20) of the jet nozzle are machined through a first single-blade forming drill; S70, the second end of a second inner conical surface (30) and the second end of the oil jet hole (20) of the jet nozzle are machined through a second single-blade forming drill; the first single-blade forming drill and the second single-blade forming drill respectively comprise a first cutter handle (110) and a first cutter head (120), each first cutter head (120) comprises a first conical section (121), each first conical section (121) is gradually contacted and extends outwards, a first cutting surface (1211) is formed on each first conical section (121) and provided with a fist scrap discharging portion, and one of two edges of each first cutting surface (1211) forms a cutting blade. According to the technical scheme, the machining method and the machining device effectively solve the problem that the inner conical surfaces of the jet nozzle are difficult to machine in the prior art.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for processing a spout and a device for processing a spout. Background technique [0002] For the processing of small high-precision micro-nozzle parts, major domestic manufacturers are located in Xi'an, Beijing, Shanghai, Zhuzhou and Guizhou. When processing the inner cone surface of the nozzle, it is mainly processed by forming and buried drilling, and after processing, polishing or abrasive flow is used to meet the requirements of the profile size and surface roughness. The cone angle of the cutting edge of the forming buried drill is the same as that of the processing surface. When processing, the cutting edge is full-loaded and the wear is relatively large. In addition, it is difficult for the tool to remove chips, and it is easy to produce chipping, resulting in poor surface quality of parts. Polishing is manual polishing, generally using a cork sti...
