Device for machining superfine oil spraying inclined holes in oil spraying plate part of oil sprayer through lasers

Abstract

The invention discloses a device for machining superfine oil spraying inclined holes in an oil spraying plate part of an oil sprayer through lasers. The device comprises a machine body. A laser machining unit which is used for machining the superfine holes and a working table which is used for bearing a workpiece to be machined and can slide back and forth along the machine body in the horizontal plane are arranged on the machine body. The laser machining unit moves up and down in the vertical direction under the drive of a driving device. The working table can freely incline within the range of 0 degree to 90 degrees relative to the horizontal plane under the drive of a driving device and can meanwhile rotate by 360 degrees at any inclined face position. The laser machining unit and the working table are matched with each other under the drive of the driving devices so that the superfine oil spraying inclined holes in the oil spraying plate part can be machined.

Description

technical field [0001] The invention belongs to the field of laser micromachining, and in particular relates to a device and method for laser machining micro-injection oblique holes on an oil-injection plate of an injector. Background technique [0002] The diameter of the fuel injection hole of the fuel injector is small, and the diameter of the fuel injection hole that meets the Euro III to Euro VI emission standards is 0.08mm to 0.17mm. In order to obtain a better fuel injection atomization effect, the fuel injection plate parts of the fuel injector Generally, multiple oblique holes are designed as oil injection holes. [0003] There are many problems in using micro-drills to drill and process the micro-slanted holes on the fuel injection plate parts. The material of the fuel injection plate parts is stainless steel (SUS 304). According to the two manuals of cutting consumption, it is best to drill holes with cemented carbide drills. The cutting speed range is 70~90m / min...

AI Technical Summary

Problems solved by technology

[0005] The above analysis shows that there are many problems in processing the fine fuel injection oblique holes of the injector with the traditional drilling method and EDM method, and the processing efficiency and processing quality are low

[0006] In the document [201310339845.9], a femtosecond laser high-efficiency precision machining device and method for the fine fuel injection hole of the automobile fuel injector is disclosed, but the patent only proposes to divide the laser beam output by the laser into multiple beams to realize the parallelism of the micro-holes of the fuel injector. A new method of processing, the specific structure of the workbench device is not given, and the specific device of how to realize the installation of the workpiece and the cooperation between the laser and the workbench is not given
