Abstract
The utility model discloses a plunger piston sleeve blank which comprises a plunger piston body (1) and an anti-thrust positioning body (2) arranged on the plunger piston body, wherein the two bodies are perpendicular to each other; the anti-thrust positioning body (2) approximately forms a rectangle shape, and both sides of the anti-thrust positioning body (2) are symmetrically provided with two kidney holes (3); the conjoint part of the plunger piston body (1) and the anti-thrust positioning body (2) arranged on the plunger piston body is provided with a transition body (4) of which the external surface is curved, and a distance between the intersection line of the transition body and the plunger piston body (1) and the intersection line of the transition body and the anti-thrust positioning body (2) is dwindled away from the middle to both sides. When the transition body is crossed with the intersection line of the plunger piston body and a flange body, the transition body forms a crescent shape. Therefore, stress concentration can be avoided, and the utility model is convenient to position. After further processed, the blank can be a plunger piston sleeve for a plunger piston pump, and can favorably insure the locomotion accuracy and the positioning accuracy of a plunger piston.
Description
Technical field
The utility model relates to a kind of part blank, especially relates to a kind of plunger bushing blank of improvement of structure.
Background technology
Plunger bushing is widely used in plunger displacement pump, and the piston of plunger displacement pump is directly installed in the plunger bushing, so the machining accuracy of plunger bushing has directly determined machine performance.For the precision that improves plunger bushing must be picked up from the blank of part.General plunger bushing blank is that turning processes, but this base substrate mostly is simple axial workpiece, is not easy the location when following process and use, thereby has influenced the final mass of product.
Summary of the invention
The utility model mainly is the technical problem that solves existing in prior technology processing and be not easy to locate when using etc., a kind of processing is provided and when using easy position ram overlap blank.
The utility model also solves the existing in prior technology plunger body simultaneously and is located between the thrust positioning body on the plunger body stress and concentrates, the technical problem of the bigger grade of processing turning amount, a kind of plunger body is provided and is located at that stress is difficult for concentrating between the thrust positioning body on the plunger body, the less plunger bushing blank of processing turning amount.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Disclosed plunger bushing blank of the present utility model comprises: plunger body 1 and be located at thrust positioning body 2 on the plunger body 1, described two bodies are perpendicular to one another, the thrust positioning body is the class cuboid, bilateral symmetry be provided with two waist holes 3.
As improvement of the present utility model, described thrust positioning body 2 also is provided with transition body 4 with plunger body 1 junction, and the outer surface of transition body 4 is curved surface, and transition body 4 is reduced to both sides by the centre gradually with the distance of the intersection of plunger body 1 and thrust positioning body 2 respectively.
One improve as of the present utility model, described transition body 4 is crossing with the intersection of plunger body 1 and thrust positioning body 2 respectively again, and promptly this transition body is crescent.
As another improvement of the present utility model, two waist holes of described thrust positioning body 2 can be symmetrically distributed.
As another improvement of the present utility model, two waist holes of described thrust positioning body 2 can be the square holes of band fillet.
As another improvement of the present utility model, two waist holes of described thrust positioning body 2 can be elliptical apertures.
As another improvement of the present utility model, the spindle nose of described plunger body 1 to and thrust positioning body 2 junctions between be the cumulative multidiameter of diameter.
As another improvement of the present utility model, can have the little fin 5 in location on the waist limit of described thrust positioning body 2 or locate little groove 6.
Therefore, the utlity model has rational in infrastructure, processing and locating easily when using, plunger body and be located at and be difficult for stress between the thrust positioning body on the plunger body and concentrate, advantage such as processing turning amount is little.
