Description
Technical field
The present invention relates to checkout gear field, particularly a kind of cuttings liquid blowoff for OCV valve.
Background technology
OCV Oil Control Valve (OCV) is one of parts important in VVT system.The control signal that it sends according to engine control system switches the oil passageway towards cam phaser and controls oil flow rate, thus reaches the object accurately controlled as opinion phase rotator.The oil channel structures of VVT: lubricating oil pump pumps up machine oil in oil sump, sends oil into oil cylinder head way by special oil duct, arrives OCV Oil Control Valve oil-in.OCV Oil Control Valve can control and distribute the hydraulic fluid port of oil to OCV Oil Control Valve on demand.Hydraulic fluid port and oil cylinder head way, the oil duct of camshaft, the oil pocket UNICOM of cam phaser, on the valve pocket of OCV valve in axial direction on be interval with multiple cannelure and be generally 3 ~ 5, and each cannelure is radially equipped with and organizes hydraulic fluid port more, when the spool of OCV valve is left or when moving right, the chamber of the hydraulic fluid port of OCV valve and the hydraulic fluid port of camshaft and cam phaser is communicated with carries out fuel feeding and oil return, reaches the object that control phase device rotates.The spool of OCV valve and valve pocket are the parts of precision-fit, that is very high to the requirement on machining accuracy of the endoporus of valve pocket, but problem is, in the manufacturing procedure of finish turning endoporus, metal fragment can scratch endoporus, thus affects the fineness of the endoporus of product, causes processing percent defective higher.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of easy to operate, cuttings liquid blowoff for OCV valve that machining accuracy is high.
The present invention's adopted technical scheme that solves the problem is: a kind of cuttings liquid blowoff for OCV valve, comprise the scroll chuck for holding workpiece, it also includes feed tube, fluid joint, spring and spool, described feed tube is connected to the rear end of described scroll chuck, and described fluid joint is located at the inner chamber of described scroll chuck and the position be placed near movable jaw, one end of described fluid joint is provided with the inlet for being connected with feed tube, described fluid joint is provided with the hollow cavity for being slidably matched with spool, described spool is made up of jut and flat part, the wall body of the hollow cavity of described fluid joint is provided with the conical surface that the inclined-plane for the jut with spool matches, obliquely on the periphery wall of described feed tube front portion be provided with multiple oblique fluid spout, the radial direction through hole that described fluid spout is provided with by spool is connected with the through hole of described spool, the other end of described fluid joint is connected with the front connector being provided with liquid outlet, and described front connector is provided with the taper speedup chamber reduced gradually to liquid outlet diameter by fluid joint, described spool be provided with through-shaft to through hole, and the through hole of described spool is connected with liquid outlet with inlet respectively, described spring is placed in the through hole of described spool, and one end of described spring is butted on the wall body of the hollow cavity of described feed tube, and the other end of described spring is butted on the inwall of the through hole of described spool.
Compared with prior art, the invention has the advantages that: this rear end being used for the scroll chuck of the cuttings liquid blowoff of OCV valve is connected with feed tube, and the inner chamber of scroll chuck is provided with fluid joint near the position of movable jaw, the hollow cavity of fluid joint is sliding combined with spool, spool is made up of jut and flat part, spool be provided with through-shaft to through hole, and the through hole of spool is connected with liquid outlet with inlet respectively.Start to add man-hour, the pressure of cuttings liquid does not need too high, and the inclined-plane of the conical surface on the wall body of the hollow cavity of fluid joint and the jut of spool is formed and seals, and cuttings liquid sprays to liquid outlet from inlet through valve core through hole, mainly plays the effect of Cooling and Lubricator.And front connector is provided with the taper speedup chamber reduced gradually to liquid outlet diameter by fluid joint, can play certain accelerating function, the ejection better effects if of cuttings liquid.When being machined to stage casing, when producing certain metal fragment, the pressure strengthening cuttings liquid reaches more than 1.2MPa, then Compress Spring band movable valve plug moves forward, a part for cuttings liquid still sprays to liquid outlet from inlet through valve core through hole, the radial direction through hole that another part is then provided with through spool sprays to oblique fluid spout, match with the cuttings liquid sprayed from liquid outlet, better can play the effect washed away by the metal fragment of OCV valve endoporus, then effectively can ensure the cleannes of the endoporus of OCV valve, Product Precision is higher, and percent defective is low.
As preferably, described oblique fluid spout and the angle of horizontal direction are 30 ~ 45 °.Like this, the better effects if of the oblique ejection of cuttings liquid, the effect washing out metal fragment is also better.
As preferably, the width of described oblique fluid spout is 1.5mm-2.2mm.Like this, more easily form water curtain, the better effects if of oblique ejection, the effect washing out metal fragment is also better.
As preferably, the quantity of described oblique fluid spout is 4.
As preferably, the conical cavity that the inlet of described fluid joint reduces gradually in diameter from outside to inside, and be provided with connecting hole between the inlet of described fluid joint and hollow cavity, and the diameter of described connecting hole is less than the diameter of inlet and hollow cavity.Like this, the effect of good speedup can be played, the better effects if of cuttings liquid ejection.
As preferably, the inclined-plane place of the jut of described spool is provided with the first sealing ring.Like this, sealing effectiveness is better, and cuttings liquid not easily leaks in joint.
As preferably, described front connector is connected with the nose threads of described fluid joint, and the front end face place of described front connector and fluid joint is provided with the second sealing ring.Like this, like this, sealing effectiveness is better, and cuttings liquid not easily leaks in joint.
