Abstract
The utility model discloses a grinding abrasion wheel of a grinding valve plate portion. The grinding abrasion wheel of the grinding valve plate portion comprises an abrasion wheel body; the peripheral surface of the abrasion 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 abrasion wheel of the grinding valve plate portion, the grinding abrasion 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 utility model relates to a kind of abrasive grinding wheel, and particularly a kind of abrasive grinding wheel of grinding Valve Disc belongs to the technical field of valve process equipment.
Background technology
Along with internal combustion engine is to the development of adjusting high load capacity direction, the more and more main height of required precision of valve.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, owing to adding, all adopt turning processing man-hour, 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.
Utility model content
Technical problem to be solved in the utility model 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 producing 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 utility model, comprise 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.The beneficial effects of the utility model: the utility model 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 labor cost, significantly improved production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the state signal that the utility model is used.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
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 utility model, 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 utility model.The utility model 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 labor cost, significantly improved production efficiency.
