Abstract
The invention discloses a grinding wheel of a grinding valve plate portion. The grinding wheel of the grinding valve plate portion comprises a grinding wheel body; the peripheral surface of the grinding wheel body is provided with an annular flange; the cross section of the annular flange is a right trapezoid; the grinding surface of the annular flange is formed by the curved surface and the conical surface which are connected into a whole through the transition surface. According to the grinding wheel of the grinding valve plate portion, the grinding wheel is designed to be the plurality of profiles and one-step forming grinding can be performed on the plate outer circle, the plate conical surface, the transition outer circle and the plate outer circle chamfering of the valve plate portion, so that the technological process is shortened, the repeated positioning is reduced, and accordingly the machining accuracy of a valve is improved and meanwhile the labor cost is reduced and the production efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of abrasive grinding wheel, particularly a kind of abrasive grinding wheel of grinding Valve Disc, belong to the technical field of valve process equipment.
Background technology
Along with the development of internal combustion engine to adjustment high load capacity direction, the more and more main height of the required precision of valve.The tradition valve adds man-hour, by the disc portion of valve, be dish cylindrical and chamfering, the dish conical surface, transition arc, three parts are processed respectively by three process, all adopt turning processing man-hour owing to adding, and because every procedure all will carry out clamping, easily, because multiple clamping produces error, therefore, the product valve precision and the presentation quality that process are poor.
Summary of the invention
Technical problem to be solved by this invention is that a kind of abrasive grinding wheel of grinding Valve Disc is provided for the deficiencies in the prior art, this abrasive grinding wheel can make equipment for grinding realize one-time positioning processing three process, reduced the error produced due to multiple clamping, thereby, greatly improved the precision of valve.
In order to solve the problems of the technologies described above, the abrasive grinding wheel of a kind of grinding Valve Disc of the present invention, comprise the emery wheel body, described emery wheel body outer peripheral face is provided with annular flange flange, the cross section of described annular flange flange is right-angled trapezium, the grinding face of described annular flange flange is comprised of arcwall face, taper surface, and described arcwall face and described taper surface link into an integrated entity by transition face.
The abrasive grinding wheel of above-mentioned a kind of grinding Valve Disc, wherein, the arc angle α of described arcwall face is 107 degree.Beneficial effect of the present invention: the present invention can be to the outer unit of the dish of Valve Disc, the dish conical surface, transition cylindrical and the outer first chamfering one-shot forming grinding of dish by emery wheel being designed to many types of, shortened technological process, reduced resetting, thereby, the machining accuracy of valve improved; And reduced the labor cost, significantly improved production efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the state signal that the present invention uses.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, in order to solve the problems of the technologies described above, the abrasive grinding wheel of a kind of grinding Valve Disc of the present invention, comprise emery wheel body 1, described emery wheel body 1 outer peripheral face is provided with annular flange flange 31, and the cross section of described annular flange flange 31 is right-angled trapezium, and the grinding face of described annular flange flange 31 is comprised of arcwall face 311, taper surface 312, described arcwall face 311 links into an integrated entity by transition face 313 with described taper surface 312, and the arc angle α of described arcwall face is 107 degree.Described flange 31 is eccentrically set on the outer peripheral face of described emery wheel 3, because described flange 31 is eccentrically set on the outer peripheral face of described emery wheel body 1, has improved the intensity of emery wheel, can extend service life of the present invention.The present invention can shorten technological process to the outer unit of the dish of Valve Disc, the dish conical surface, transition cylindrical and the outer first chamfering one-shot forming grinding of dish by emery wheel being designed to many types of, has reduced resetting, thereby, improved the machining accuracy of valve; And reduced the labor cost, significantly improved production efficiency.
Claims (2)
1. the abrasive grinding wheel of a grinding Valve Disc, comprise the emery wheel body, it is characterized in that, described emery wheel body outer peripheral face is provided with annular flange flange, the cross section of described annular flange flange is right-angled trapezium, described annular flange flange grinding face is comprised of arcwall face, taper surface, and described arcwall face and described taper surface link into an integrated entity by transition face.
