Fig. 3 is the structural representation of the utility model wheel grinding valve part;
In figure: 1-emery wheel body, 2-straight trough, 3-annular groove, 4-bevel grinding face, the 51-valve retainer conical surface, 52-air valve cervix, 53-engine valve stem, 54-valve retainer end, 55-valve retainer end chamfering.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only wherein part embodiment of the utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 1 to 3, a kind of engine valve forming grinding wheel, comprise emery wheel body 1, described emery wheel body 1 excircle end face is provided with the first flour milling mating with the valve retainer conical surface 51, air valve cervix 52 and engine valve stem 53 profiles, and described emery wheel body 1 side arranges bevel grinding face 4 that can grinding valve retainer end chamfering 55.
As preferred version of the present utility model, described emery wheel body 1 side is provided with the second flour milling that can grinding valve retainer end 54.
As the further preferred version of the utility model, annular groove 3 can be set up in described emery wheel body 1 side, and described emery wheel body 1 side circumference can be set up the straight trough 2 that is communicated with annular groove 3.The degree of depth and the width of described annular groove are 2～4mm; The degree of depth of described straight trough is 2～4mm, and width is 4～8mm.The design of annular groove and straight trough, can effectively discharge a large amount of chips, greatly reduces the probability that emery wheel stops up, and has improved wheel life, grinding fluid can be carried and is put in place again, really plays the cooling effect of the sliding ﹑ of profit, avoids the burn of valve, has guaranteed grinding quality.
