Cutting fluid spraying device for OCV valve

Abstract

The invention discloses a cutting fluid spraying device for an OCV valve. The cutting fluid spraying device includes a three-jaw chuck for clamping a workpiece, wherein a fluid inlet pipe is connected with the rear end of the three-jaw chuck, a fluid outlet joint is arranged in the inner cavity of the three-jaw chuck and positioned at a position close to the movable jaws, the fluid outlet joint is arranged in the hollow inner cavity matched with the valve element in a sliding manner, the valve element is composed of a flat part and a protruded part arranged sequentially, a conical surface for being matched with the inclined surface of the protruded part of the valve element is arranged on the wall body of the hollow inner cavity of the fluid outlet joint, and a plurality of slant fluid outlet nozzles are arranged on the outer circumferential wall of the front part of the fluid inlet pipe along the circumferential direction; a spring is arranged in a through hole of the valve element, and one end of the spring abuts against the wall body of the hollow inner cavity of the fluid inlet pipe while the other end of the spring abuts against the inner wall of the through hole of the valve element. The cutting fluid spraying device for the OCV valve is convenient to operate and high in machining precision.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to a cutting fluid ejection device for an OCV valve. Background technique [0002] The oil control valve (OCV) is one of the important components in the VVT ​​system. It switches the oil channel to the cam phaser and controls the oil flow according to the control signal sent by the engine control system, so as to achieve the purpose of precisely controlling the phase rotation angle. The oil passage structure of the variable valve timing system: the oil pump pumps the oil from the oil pan, sends the oil to the oil passage of the cylinder head through a special oil passage, and reaches the oil inlet of the oil control valve. The oil control valve controls and distributes oil to the ports of the oil control valve as required. The oil port communicates with the oil passage of the cylinder head, the oil passage of the camshaft, and the oil chamber of the cam phaser. The valve sleeve of...

AI Technical Summary

Problems solved by technology

The spool and valve sleeve of the OCV valve are precisely matched parts, which means that the processing accuracy of the inner hole of the valve sleeve is very high, but the problem is that in the process of finishing the inner hole of the car, metal debris will scratch Inner hole, which affects the smoothness of the inner hole of the product, resulting in a high processing waste rate
