The method comprises the following process flows: 1. analyzing the structure between each valve hole in a valve body and an oil groove and mainly considering the relevant dimensions such as the valve hole diameter, the valve hole depth, the oil groove width and the like; 2. designing and manufacturing a special tool for removing the burrs at the inlets and outlets of the valve holes; and 3. using the processed tool to remove the burrs at the inlets and outlets of the valve holes in the valve body. The method has the following beneficial effects: the burrs at the joints of the valve holes in the valve body and the oil groove can be simply, conveniently and quickly removed by adopting the method, thus alleviating the labor intensity of workers, improving the production efficiency and ensuring the product quality; and the method has the advantages of simpleness in operation, low cost and wide range of application.
Description
Technical field
The present invention relates to a kind of processing method of removing valve body inner orifice burr, belong to field of machining.
Background technology
Circular hole be processed with boring, reaming, bore hole, fraising, extruded hole etc., the processing back produces burr in the import in hole with outlet.The method of removing the aperture burr now mainly is manual with scraper or sand paper deburring.But for valve body and similar parts, because its inner valve opening and many oil grooves are connected, the burr in hole and oil groove junction is difficult to remove totally with the mode of scraper or sand paper through manual, and scratches aperture and hole wall easily.When hole or groove hour, scraper or hand stretch less than, can't remove the aperture burr.If it is unclean that the interior hole bur of valve body and similar parts is removed, the mobile of spool is obstructed, and will cause the properties of product instability maybe can't work.
Summary of the invention
The objective of the invention is to: provide a kind of simple, convenient, fast, remove the processing method of valve body inner orifice burr reliably; Can effectively remove the burr of valve inner valve opening and oil groove connection place after using this method, thereby overcome the drawback that conventional method is difficult to remove this type of burr.
The present invention is achieved in that it may further comprise the steps:
The first, the structure between analysis each valve opening of valve inner and the oil groove, emphasis is considered relative dimensions such as valve opening diameter, the valve opening degree of depth, oil groove width;
The second, the dedicated tool of valve opening import and export burr is removed in design, manufacturing;
1, Tool Design
Cutter adopts integral structure, has a groove in the middle of the knife bar, and the knife bar slotted section has than strong elasticity, the inwardly compression of back that is squeezed, and external force automatically restores to nature after disappearing, and the length of knife bar groove is than the big 50mm～150mm of the valve opening degree of depth; Tool bit diameter φ D removes the aperture 1mm～4mm (occurrence is confirmed according to pore size) in the hole of burr greater than need; Cutter head fillet R value be tool bit diameter φ D (0.01～0.03) doubly; Cutter head thickness L3 confirms according to the oil groove width; Value be oil groove width (0.5～0.7) doubly, thereby guarantee that cutter head can stretch in the oil groove; The size of cutter head groove width L1 confirms that apart from the size of L2 and tool bit diameter φ D the cutter head sword is less than valve opening aperture 0.5mm～2mm apart from L2 by the cutter head sword; Knife bar diameter phi D1 value be tool bit diameter φ D (0.5～0.8) doubly, knife bar springhole diameter phi D2 value be knife bar diameter phi D1 (0.4～0.9) doubly, knife bar groove width L4 is than the little 1mm～4mm of knife bar springhole diameter phi D2; The blade of cutter head and cutter spindle reach the best effect of removing burr to becoming 45 to guarantee it, can play guide effect when cutter head stretches into, withdraws from valve opening and the oil groove of valve inner simultaneously; The surface roughness of cutter head and cutter head fillet R is higher 1～2 grade than the surface roughness in burr hole; The shank portion of cutter is processed through annular knurl, the frictional force when increasing with the hand rotary cutter.
2, cutter manufacturing
Cutter material is selected the bar of alloy tool steel such as 9SiCr for use, through machining process such as turning, heat treatment, mill, line cutting, grindings, it is processed as the dedicated tool of the removal burr of adhere to specification (as shown in fig. 1).
Three, use the cutter of being processed to remove valve body inner valve hole import and export burr.
With the knife bar of hand squeezing knife tool slotted section, the inwardly compression of cutter head part, promptly tool bit diameter diminishes; Cutter is extend into the oil groove place through valve body inner bore; Unclamp knife bar then, cutter head partly returns to nature, and promptly tool bit diameter is got back to initial value; Be close to the import department or the exit of endoporus to blade, firmly the burr removing that can will locate of the handle of a knife of rotary cutter is clean.
The present invention has utilized the elasticity of fluting knife bar; Make cutter head can stretch into, withdraw from the valve opening and the oil groove of valve inner freely; Through manual rotation handle of a knife, the blade of cutter will thoroughly have been removed the burr of valve inner valve opening and oil groove junction, and endoporus and hole wall can not be scratched.Adopt the present invention can remove burr accurately, quickly and easily, thereby alleviate working strength of workers, enhance productivity, guarantee product quality.

The specific embodiment
Embodiments of the invention: with Fig. 3 is example, describes in conjunction with Fig. 1.
The first, the structure between analysis each valve opening of valve inner and the oil groove, emphasis are considered relative dimensions such as valve opening diameter phi Da, valve opening degree of depth La2, oil groove width La1;
The second, the dedicated tool of valve opening import and export burr is removed in design, manufacturing;
1, Tool Design
As shown in fig. 1, cutter adopts integral structure, has a groove in the middle of the knife bar, and the knife bar slotted section has than strong elasticity, the inwardly compression of back that is squeezed, and external force automatically restores to nature after disappearing.
The design of each relative dimensions of cutter is following:
(1) tool bit diameter φ D value is valve body aperture φ Da+ (1mm～4mm);
(2) knife bar diameter phi D1 value is (0.5～0.8) * tool bit diameter φ D;
(3) cutter head thickness L3 value is oil groove width La1 * (0.5～0.7), thereby guarantees that cutter head can stretch in the oil groove;
(4) cutter head fillet R value is (0.01～0.03) * tool bit diameter φ D;
(5) size of cutter head groove width L1 is confirmed apart from the size of L2 and tool bit diameter φ D by the cutter head sword, the cutter head sword apart from L2 less than valve opening aperture 0.5mm～2mm;
