Air valve machining device with angle-adjustable cutters

Abstract

The invention discloses an air valve machining device with angle-adjustable cutters. A first motor, a second motor and a rotating motor are installed on a cutter support, wherein the first motor is used for adjusting the vertical positions of the cutters, and the second motor is used for adjusting the positions of the cutters in the direction of an air valve shaft. The cutters can be directly installed by rotating the motors, the machining angles of the cutters can be adjusted and radian machining of arc surfaces can be achieved. The air valve machining device with the angle-adjustable cutters eliminates protruding edges probably generated between the two cutters, ensures that carbon is not easily accumulated when the air valve arc surfaces work, prolongs the service life of an air valve and accordingly increases the power of an engine and prolongs the service life of the engine.

Description

technical field [0001] The invention relates to the technical field of valve processing, in particular to a valve processing device with adjustable tool angle. Background technique [0002] The valve is an important component of the engine. It is responsible for inputting air into the engine and removing the exhaust gas after combustion. It is divided into an intake valve and an exhaust valve in structure. The intake valve sucks air into the engine, mixes it with fuel, and exhausts The door is to take the burned exhaust gas out of the engine and dissipate heat. According to the finished structure of the valve, it is usually divided into a whole valve, a bimetal butt welded valve and a hollow sodium-filled valve. The intake valve is made of medium carbon alloy steel; the exhaust valve needs to be made of heat-resistant alloy steel due to higher working temperature. In order to save cost, the head of the exhaust valve is made of heat-resistant alloy steel, and the rod is made...

AI Technical Summary

Problems solved by technology

[0004] The arc surface 4 of the valve has a great influence on the air flow, and the processing of the arc surface 4 of the valve directly affects whether the stress distribution on the surface of the arc surface 4 of the valve is uniform. When the exhaust gas passes through the exhaust valve, carbon deposits will be generated on the arc of the exhaust valve neck, which will seriously affect the service life of the valve and the reliability of the whole machine

However, the machining tools in the prior art cut the valve arc surface 4 by adjusting the height up and down and left and right. This machining method has no problem for plane machining, but it cannot guarantee the arc surface machining. The arc surface is smooth, and there may be convex edges between two adjacent blades, which cannot further reduce the surface roughness, making the arc surface of the valve easy to deposit carbon during work, reducing the service life of the valve, and affecting the power and service life of the engine
