Clamping and fixing device for oil nozzle of automobile

Abstract

The invention discloses a clamping and fixing device for an oil nozzle of an automobile. The device comprises a limiting base, a receding fixing clamping block, a positioning clamping seat and an oilnozzle workpiece; the limiting base is provided with the positioning clamping seat and is fixedly connected with the positioning clamping seat by welding; the upper end of the oil nozzle workpiece issleeved with the positioning clamping seat, and the oil nozzle workpiece is in rotary separated connection with the limiting base; and the side end of the receding fixing clamping block is sleeved with the positioning clamping seat, the oil nozzle workpiece is fixed by the receding fixing clamping block, and the receding fixing clamping block is fixedly connected with the positioning clamping seatthrough a fixing part. According to the device, a threaded groove and a threaded convex rod are fixedly connected, so that the oil nozzle workpiece and the limiting base are primarily fixed, and meanwhile, the installation and disassembly are convenient; through the receding fixing clamping block and the positioning clamping seat, the oil nozzle workpiece is fixed again so that the oil nozzle workpiece can be effectively prevented from shaking all around during machining, and the fixing effect is good; and multiple oil nozzle workpieces can be clamped and fixed by the device so that the multiple workpieces can be machined at the same time, and the machining efficiency is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of auto parts, in particular to a clamping and fixing device for an automotive fuel injection nozzle. Background technique

[0002] In the automotive industry, the requirements for its components are often high, especially for the core components of its engine. As the fuel input port of the engine, the fuel injector has strict requirements on the oil supply at every beat. Too much will cause insufficient combustion, and finally the excess fuel will cause environmental pollution and energy waste through exhaust emissions. Too little will cause The power supply of the engine is insufficient, and the performance of the engine cannot be fully reflected. Therefore, the quality of fuel injectors is the top priority in the automotive industry. When the existing automotive fuel injector is being processed, the clamping fixture is extremely poor in fixity, which can easily cause the flange ring of the automobile to...
