Abstract

The invention discloses a positioning and wall protection device for a nozzle hole of a laser processing fuel injection nozzle. Coinciding with the central axis of the base, the upper end of the central positioning pin is provided with a central revolving inner hole; the protection inner core includes an inner fixed spring, a push rod plug and a push rod, and the protection inner core is installed in the center of the central positioning pin. In the rotary inner hole; a fixing mechanism, which includes an oil nozzle pressing block and a pressing block fixing seat, the oil nozzle pressing block is used for fixing the center positioning pin, and the pressing block fixing seat is used for fixing the oil nozzle pressing block. The invention can prevent the inner wall from being damaged during laser processing of the fuel injection nozzle.

Description

technical field [0001] The invention relates to the field of processing, in particular to a positioning and wall protection device for laser processing fuel injector nozzles. Background technique [0002] Based on the increasingly stringent emission regulations, more and more stringent requirements are put forward for the diameter, shape, position of the hole and the flow coefficient of the nozzle. At present, the method of processing the nozzle hole of the fuel nozzle mainly adopts the traditional drill bit machining The main determination of these two processing methods is that the processing accuracy makes it impossible to process the oil injection hole with a diameter of less than 0.12mm. In recent years, with the development of laser processing technology, the technology of using laser to process the nozzle hole of fuel injector will replace the technology of mechanical processing and electric processing. Laser micro-hole processing has the advantages of high precision...
