Abstract
The utility model relates to a localizer convenient for determining spherical center during grinding of valve ball of ceramic ball valve, which comprises a locating main shaft, wherein, the top end of the locating main shaft is provided with a locating bowl, the inside of the locating bowl is provided with a partly orbicular curved surface, the spherical center of the partly orbicular curved surface is positioned on the axial line of the locating main shaft. The utility model guarantees processing precision and is convenient for mass industrial production; meanwhile, the locating bowl can be easily replaced, thereby being suitable for processing spheres of various diameters.
Description
Technical field
The utility model relates in a kind of valve ball mill process at ceramic ball valve to be convenient to determine the employed locator of ball centre, belongs to processing equipment accessory technical field.
Background technology
When ceramic valve ball is contained in when locating on the frock, the center of its ball must accurately fix on the cross centre line crosspoint in space.Otherwise the center line of ball is not just at the center of ball.Owing to off-centring causes the rotary switch difficulty, have a strong impact on and close precision and may cause seepage even the damage valve ball during assembling.In general be the center that on this spherical, to find each ball, draw center line, go up the range estimation contraposition of depending on the people behind the machine again by line.But because ball at this moment is that blank is irregular, putting off until some time later the bistrique emery wheel all can not have its clear and definite center to proofread.So so-called only is some experiences to the center, do not have science, accurately locate reliably, this is one of key of can not doing now qualified valve ball.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of quick locator of spheroid mill precision machining that can fast, accurately determine ball centre in the valve ball mill process of ceramic ball valve is provided.
Technical scheme according to the utility model provides is provided with the location bowl in the top ends of locating main shaft, in the bowl of described location the curved surface that is the part sphere is arranged, and the centre of sphere of this sphere curved surface is on the axis of location main shaft.
The location bowl is connected the top ends of location main shaft, and the location bowl utilizes gland and the screw be located under it to be installed on the main shaft of location.Curved surface in the bowl of described location is hemispherical.
The beneficial effects of the utility model are: can fast, accurately determine ball centre to have guaranteed machining accuracy, be convenient to suitability for industrialized production on a large scale, and locate bowl and can easily change, be applicable to the processing of various diameter sphere.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is that the utility model is applied to the schematic diagram that spheroid adds man-hour.
The specific embodiment
As shown in Figure 1, top ends at location main shaft 1 is provided with location bowl 2, in the location bowl 2 curved surface that is half sphere is arranged, location bowl 2 removably is connected the top ends of location main shaft 1, location bowl 2 is arranged on the main shaft 1 of location by gland 3 and the screw of being located under it 4, and the centre of sphere of this sphere curved surface is on the axial location of location main shaft 1.
Owing on the bed surface of the cross spider of the bistrique center line of lathe and two thimbles, held the locating hole of the location main shaft 1 that locator of the present utility model is installed in advance successfully.
During use, one end of location main shaft 1 promptly inserts some degree of depth in this existing locating hole, guarantee that the center of main shaft 1 accurately is positioned at the center of requirement, the centre of sphere of location bowl 2 sphere curved surfaces is on the axial location of location main shaft 1, so at this moment the centre of sphere of location bowl 2 sphere curved surfaces is set on bistrique center line and two top 6 the position of cross spider exactly.Put into location bowl 2 as long as at this moment will treat the workpiece spheroid, just can finish the location quickly and easily automatically.Top 5,6 of lathe two ends are headed in the centre bore of anchor clamps main shaft 1 again, clip the workpiece spheroid, location work promptly easily declares to be finished, and the location is accurately errorless.Once more during dismounting, the right top 6 is withdrawed from, locator of the present utility model is taken away, shaking handle again is moved to the left the right top 6, and it is the workpiece spheroid is very good, at this moment because of the left side top 5 has maintained static,, just manufacturing procedure can have been begun so workpiece spheroid at this moment is consistent with the centre of sphere of processing back valve ball.When changing next part workpiece spheroid, as long as the right top 6 is withdrawed from, change new blank withstand on earlier the left side fixing top 5 on, shake handwheel then, will top 5,6 withstand the workpiece spheroid once more, also just accurately located.The product completion of processing of having only this batch specification just will be used the location bowl 2 with its coupling once more in the time of will changing the product of different size, be positioned on the same location main shaft 1 and just can have accurately located once more.
