Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 1 As shown, the present invention provides a device for laser processing the fine fuel injection oblique holes on the fuel injection plate parts of the fuel injector, including three major parts: the fuselage, the laser processing unit and the workbench; the fuselage is equipped with There is a laser processing unit for micro-hole processing and a workbench for carrying the workpiece to be processed and sliding back and forth in the horizontal plane along the fuselage. The laser processing unit moves up and down in the vertical direction driven by the driving device; Driven by the driving device, the workpiece table can be arbitrarily tilted within the range of 0-90 degrees relative to the horizontal plane and can be rotated 360 degrees at any inclined position within the range of 0-90 degrees; and the laser proc...

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...
