Abstract
The utility model discloses a kind of not fragile oil sealing in assembling process and the assembly tooling of the fracturing pump small rod oil sealing of assembling speed can be improved, comprise distending cover and transition block, described distending cover is made up of centrum, cylinder, fixed block, described centrum is Rotary-table, it is large end and diameter is equal with cylinder near cylinder end, the diameter of described cylinder is identical with small rod diameter, and described fixed block is located at cylinder one end away from centrum; Be mounted with small rod by distending cover in described fixed block loading cell body, described fixed block overlaps with small rod center line in the axial centerline of small rod axial section.The utility model reduces cost of goods manufactured greatly, and the scrappage of oil sealing is almost 0, and makes assembling speed improve nearly 10 times.
Description
Technical field
The utility model relates to a kind of fracturing pump part, particularly relates to a kind of assembly tooling of fracturing pump small rod oil sealing.
Background technology
Current fracturing pump small rod oil sealing is import oil sealing, and its price is 100 times of domestic oil sealing, common assembling mode be directly by oil-sealing sleeve on small rod, this can make oil seal lip damaged, thus causes oil sealing to be scrapped.Add manufacturing cost and assembling risk greatly, and assembling speed is slow, production efficiency is low.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of not fragile oil sealing in assembling process and can improves the assembly tooling of the fracturing pump small rod oil sealing of assembling speed.
For achieving the above object, the utility model provides a kind of assembly tooling of fracturing pump small rod oil sealing, it is characterized in that: comprise distending cover and transition block, described distending cover is made up of centrum, cylinder, fixed block, described centrum is Rotary-table, it is large end and diameter is equal with cylinder near cylinder end, and the diameter of described cylinder is identical with small rod diameter, and described fixed block is located at cylinder one end away from centrum;
Be mounted with small rod by distending cover in described fixed block loading cell body, described fixed block overlaps with small rod center line in the axial centerline of small rod axial section.
Further, it is characterized in that: described transition block is 1/2nd annulus identical with small rod diameter, its to load in short slot and outer surface and small rod outer surface on the same face.
Further, described transition block has two pieces.
The beneficial effects of the utility model are: the utility model reduces cost of goods manufactured greatly, and the scrappage of oil sealing is almost 0, and make assembling speed improve nearly 10 times.
Accompanying drawing explanation
Fig. 1 is the structural representation of the assembly tooling detailed description of the invention of the utility model one one kinds of fracturing pump small rod oil sealings.
Fig. 2 is the enlarged drawing of A in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See Fig. 1 Fig. 2, a kind of assembly tooling of fracturing pump small rod oil sealing, comprise distending cover 1 and transition block 2, described distending cover 1 is made up of centrum 11, cylinder 12, fixed block 13, described centrum 11 is Rotary-table, it is large end and diameter is equal with cylinder 12 near cylinder 12 end, and the diameter of described cylinder 12 is identical with small rod 3 diameter, and described fixed block 13 is located at cylinder 12 one end away from centrum 11;
Described fixed block 13 loads in cell body 32 and is mounted with small rod 3 by distending cover 1, and described fixed block 13 overlaps with small rod 3 center line in the axial centerline of small rod 3 axial section;
Described transition block 2 is 1/2nd annulus identical with small rod 3 diameter, its to load in short slot 31 and outer surface and small rod 3 outer surface on the same face, described transition block 2 has two pieces, is is just in time filled and led up by short slot 31 during use.
During use, first distending cover 1 is assembled with transition block 2 and small rod 3, then progressively promote oil sealing 4 from the centrum small end of distending cover 1 to assemble towards installation direction 5, because centrum 11 can play the effect of guiding when assembling, and guide oil sealing progressively to slide into cylinder from small end and slide into again small rod, whole process seamlessly transits, and effectively can prevent the breakage of oil seal lip, has both improve production efficiency and has again reduced percent defective.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
Claims (3)
