Abstract
The utility model discloses a datum for grinding the inner diameter of a stopping ring, which has simple structure, is practical and can guarantee the grinding quality. The datum comprises a cylindrical side wall, and the bottom part of the cylindrical side wall is provided with a closed end; and the center of the closed end is provided with a connecting part which is used to fixedly connected with a main shaft of a grinding machine.
Description
Technical field
The utility model relates to a kind of aid that is used to grind the locating snap ring internal diameter, relates in particular to a kind of benchmark that is used to grind the locating snap ring internal diameter.
Background technology
Usually adopt the method in the outer mill during mill locating snap ring internal diameter, in the mill process,, will certainly cause workpiece, influence grinding quality along axial wobble if workpiece only relies on the outward flange of two support foot location workpiece on the grinding machine.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, and practicality can guarantee the benchmark that is used to grind the locating snap ring internal diameter of grinding quality.
The utility model comprises sidewall cylindraceous, in the bottom of described sidewall cylindraceous one blind end is set; Be provided with one at the center of above-mentioned blind end and be used for the connecting portion that the main shaft with grinding machine is mutually permanently connected.
Benchmark in the utility model is fixedlyed connected with the main shaft of grinding machine by means of above-mentioned connecting portion, and the upper surface of sidewall cylindraceous is used for a plane of holding workpieces, the outward flange of two support foot location workpiece on the grinding machine.By the location of three parts, when having avoided mill locating snap ring internal diameter locating snap ring along axial wobble, thereby guaranteed grinding quality.
Preferably, on sidewall cylindraceous, set out the bits through hole.Describedly go out to consider to be worth doing preferably four of through holes, four to go out to consider to be worth doing through hole contour with respect to blind end, evenly distributes on sidewall cylindraceous.
When carrying out grinding to workpiece towards cooling fluid so that to workpiece cooling, dedusting, the scrap of generation flows out by going out to consider to be worth doing through hole.
Preferably, in the centre position of described blind end downside one boss is set.
With benchmark and main shaft attended operation the time, boss can play in the effect spacing with the main shaft vertical direction.
Preferably, described connecting portion is a tapped through hole.
Preferably, three standby tapped through holes are set on blind end, described three standby tapped through holes with above-mentioned tapped through hole be the center be evenly distributed on above-mentioned tapped through hole around.
When tapped through hole damages, can link to each other with main shaft by bolt by means of above-mentioned three equally distributed standby tapped through holes.
Preferably, described connecting portion is a bolt, and described bolt is connected on the downside of above-mentioned blind end.

The specific embodiment
As depicted in figs. 1 and 2, the benchmark in the present embodiment comprises sidewall 1 cylindraceous, and a blind end 2 is set in the bottom of described sidewall 1 cylindraceous.One tapped through hole 3 is set at the center of described blind end 2.Three standby tapped through holes 4 are set on blind end 2 in addition, described three standby tapped through holes 4 with above-mentioned tapped through hole 3 be the center be evenly distributed on above-mentioned tapped through hole 3 around.
On above-mentioned sidewall 1 cylindraceous, be provided with four with respect to blind end contour go out to consider to be worth doing through hole 5, above-mentioned four go out to consider to be worth doing through hole 5 and evenly distribute.
In addition, at the center of blind end 2 downsides one boss 6 is set.
Benchmark is fixedlyed connected with the main shaft of grinding machine by means of above-mentioned tapped through hole 3, and the upper surface of sidewall 1 cylindraceous is used for a plane of holding workpieces, and two support foots on the grinding machine are then located the outward flange of workpiece.
As shown in Figure 3 and Figure 4, the benchmark in the present embodiment comprise sidewall 1 cylindraceous ', described sidewall 1 cylindraceous ' the bottom be provided with a blind end 2 '.Connect in the center of above-mentioned blind end 2 ' downside a bolt 3 '.
In addition, above-mentioned sidewall 1 cylindraceous ' on be provided with four with respect to blind end contour go out to consider to be worth doing through hole 4 ', above-mentioned four go out to consider to be worth doing through hole 4 ' evenly distribute.
Benchmark is by means of above-mentioned bolt 3 ' fixedly connected with the main shaft of grinding machine, sidewall 1 cylindraceous ' the upper surface be used for a plane of holding workpieces, the outward flange of two support foots location workpiece on the grinding machine.
