Abstract
The utility model provides a grinding wheel for grinding a valve collet slot, which enables grinding for the valve collet slot to be high in production efficiency and low in production cost. The grinding wheel is characterized by comprising an internal metal structure body, wherein the cylindrical grinding surface of a CBN (cubic boron nitride) grinding material is attached to the excircle surface of the metal structure body, and the cylindrical grinding surface of the CBN grinding material is an outwards convex surface and embedded in a groove of the moulded valve collet slot.
Description
Technical field
The utility model relates to the structure field of emery wheel, is specially a kind of emery wheel of grinding valve collet groove.
Background technology
Plain wheel is all adopted in the grinding of existing valve collet groove, its need diamond roller to the peripheral milling bevel of emery wheel be trimmed to have the convex surface that the groove with the valve collet groove matches after; Through convex surface grinding valve collet groove; Because the intensity difference of plain wheel, cause with the valve collet groove quantity of the wheel grinding behind the diamond roller trimming few, so the needs diamond roller that utilizes repeatedly remove to repair plain wheel; Just can guarantee then has enough wheel grinding valve collet grooves; And then cause the production efficiency of grinding valve collet groove low, and the plain wheel that need expend is many, so its production cost is high.
Summary of the invention
To the problems referred to above, the utility model provides a kind of emery wheel of grinding valve collet groove, and it makes the production efficiency of grinding valve collet groove high, production cost is low.
A kind of emery wheel of grinding valve collet groove, its technical scheme is such:
It is characterized in that: it comprises the interior metal structure, the fit periphery of said metal structure of the peripheral milling bevel of CBN abrasive material, and the peripheral milling bevel of said CBN abrasive material is outer convex surface, it is embedded in the groove of the valve collet groove after the moulding.
It is further characterized in that: said interior metal structure is a casting, and the periphery of said metal structure is outer convex surface, the groove of said valve collet groove after the chimeric moulding of said outer convex surface;
The peripheral milling bevel of said CBN abrasive material is evenly arranged in the outer convex surface of said interior metal structure, and thickness is identical.
After adopting the structure of the utility model, because emery wheel has comprised interior metal body structure, outside CBN abrasive material, and the peripheral milling bevel of CBN abrasive material is outer convex surface; And be embedded in the groove of the valve collet groove after the moulding; Need not to pass through again the grinding-shaping of diamond roller, so its manufacturing is simple, and because the good rigidity of CBN abrasive material; So the good emery wheel that causes making can a plurality of valve collet grooves of grinding, so its production efficiency is good, production cost is low.
Description of drawings
Fig. 1 is the front view structural representation of the utility model;
Fig. 2 is the vertical view structural representation of Fig. 1.
The specific embodiment
See Fig. 1, Fig. 2; It comprises interior metal structure 1, the periphery 3 of the peripheral milling bevel 2 applying metal structures 1 of CBN abrasive material, and the peripheral milling bevel 2 of CBN abrasive material is outer convex surface; It is embedded in the groove 5 that valve after the moulding is locked 4 clip slots; Interior metal structure 1 is a casting, and the periphery 3 of metal structure 1 is outer convex surface, and valve is locked the groove 5 of 4 clip slots after the chimeric moulding of outer convex surface; The peripheral milling bevel 2 of CBN abrasive material is evenly arranged in the outer convex surface of interior metal structure, and thickness is identical.
Claims (3)
