Description
Technical field
The utility model relates to a kind of component of plunger pump, especially the split type rear cover structure of location, oil distribution casing outer ring.
Background technique
Oil distribution casing is as one of plunger pump strength member, and it is fixed on the bonnet of plunger pump; At present, the fixing of oil distribution casing adopts excircle orientation more, and namely on bonnet, process a groove, oil distribution casing is embedded in this groove, the outer wall of oil distribution casing is close to mutually with the sidewall of groove and forms location, and the bottom surface of oil distribution casing is close to mutually with the bottom surface (attachment face of oil distribution casing) of groove.
But the processing request of above-mentioned excircle orientation structure to groove is high, planeness and the roughness of bonnet oil distribution casing attachment face in course of working are difficult to ensure card, if and cylindrical position, oil distribution casing location is damaged or distortion of colliding with during after-sales service, then whole bonnet needs to scrap, cause waste of material, increase maintenance cost.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, provides structure simple, easy to process, the split type rear cover structure of the location, oil distribution casing outer ring that maintenance cost is low.
The utility model solves the problems of the technologies described above adopted technological scheme:
The split type rear cover structure of location, oil distribution casing outer ring, comprise bonnet main body, bonnet main body offers filler opening and oil outlet, filler opening is communicated with oil distribution casing by oil inlet passage, oil outlet is communicated with oil distribution casing by oil discharge passage, bonnet main body is provided with annular groove, is equipped with oil distribution casing positioning ring in this annular groove, and oil distribution casing positioning ring is shaped with the locating slot suitable with the cylindrical of described oil distribution casing.
The technical measures optimized also comprise:
The middle part of above-mentioned oil distribution casing positioning ring is formed with stepped part, and the height of this stepped part is lower than the degree of depth of described annular groove.
The bottom of above-mentioned oil distribution casing positioning ring is shaped with chamfering.
Above-mentioned bonnet main body offers positioning pin hole.
Above-mentioned filler opening and oil outlet are symmetricly set in described bonnet main body.
The center of above-mentioned bonnet main body is provided with bearing mounting hole.
The split type rear cover structure of location, oil distribution casing outer ring of the present utility model, adopts and arranges annular groove in bonnet main body, be equipped with oil distribution casing positioning ring in this annular groove, oil distribution casing positioning ring is shaped with the locating slot suitable with the cylindrical of oil distribution casing.Forming split type rear cover structure by arranging oil distribution casing positioning ring, the oil distribution casing positioning ring playing positioning action being separated, greatly facilitates the processing of locating slot; And oil distribution casing positioning ring can be taken off separately in maintenance process and keep in repair, even if locating slot well damage needs to change, only needing to change oil distribution casing positioning ring, without the need to being changed by whole bonnet, greatly having saved maintenance cost.
In addition, the middle part of oil distribution casing positioning ring is formed with stepped part, and the height of this stepped part is lower than the degree of depth of described annular groove; When such oil distribution casing positioning ring is fit in annular groove, stepped part is absorbed in annular groove, thus ensures that oil distribution casing can be close to bonnet after installing mutually.

Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Be structural representation of the present utility model as shown in Figures 1 to 4,
Reference character is wherein: bonnet main body 1, annular groove 1a, filler opening 11, oil inlet passage 11a, oil outlet 12, oil discharge passage 12a, positioning pin hole 13, bearing mounting hole 14, oil distribution casing 2, oil distribution casing positioning ring 3, locating slot 3a, stepped part 3b, chamfering 31, locating stud 4, bearing 5.In Fig. 1, the direction of arrow represents the loading direction of oil distribution casing positioning ring 3.
As shown in Figures 1 to 4,
The split type rear cover structure of location, oil distribution casing outer ring, comprise bonnet main body 1, bonnet main body 1 offers filler opening 11 and oil outlet 12, filler opening 11 is communicated with oil distribution casing 2 by oil inlet passage 11a, oil outlet 12 is communicated with oil distribution casing 2 by oil discharge passage 12a, bonnet main body 1 is provided with annular groove 1a, is equipped with oil distribution casing positioning ring 3 in this annular groove 1a, oil distribution casing positioning ring 3 is shaped with the locating slot 3a suitable with the cylindrical of described oil distribution casing 2.
In embodiment, the middle part of oil distribution casing positioning ring 3 is formed with stepped part 3b, and the height of this stepped part 3b is lower than the degree of depth of described annular groove 1a.
Design like this, when oil distribution casing positioning ring 3 is loaded in annular groove 1a, stepped part 3b can enter in annular groove 1a completely, and the assembling of projection to oil distribution casing 2 avoiding stepped part 3b has an impact; After oil distribution casing 2 has assembled, its surface is close to mutually with the surface of bonnet main body 1.
In embodiment, the bottom of oil distribution casing positioning ring 3 is shaped with chamfering 31.Convenient when the setting of chamfering 31 can not enable oil distribution casing positioning ring 3 load, and avoid oil distribution casing positioning ring 3 bottom and there is wedge angle, avoid wedge angle to cause scuffing to part surface.
