Abstract
The utility model discloses the fracturing pump shoulder pole centralizer frock that a kind of structure is simple, clamping stability is good, comprise shoulder pole centralizer, pedestal, set bolt, described pedestal is disc, centre has through hole, outer ledge has a circle positioning convex, and described positioning convex thickness is not more than the thickness of the shoulder pole centralizer being in contact with it part; Described shoulder pole centralizer snaps in positioning convex, and end is pressed with briquetting, and set bolt is assembled into entirety through briquetting and pedestal.The utility model structure is simple, low cost of manufacture; By using frock, the qualification rate of Related product is made to bring up to 95% by original 75%.
Description
Technical field
The utility model relates to a kind of fracturing pump, particularly relates to a kind of clamping tool of fracturing pump shoulder pole centralizer.
Background technology
Need to carry out turning to its outer surface in fracturing pump shoulder pole centralizer manufacturing procedure, but due to shoulder pole centralizer shape special, three of lathe directly can not be used to grab chuck and to clamp; Existing employing auxiliary clamp grabs gripper chuck clamper with three after clamping again at present, then process shoulder pole centralizer, but these fixtures or structure is too complicated, or uses inconvenience, not clamping workpiece to be processed, cause product percent of pass on the low side.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide the shoulder pole centralizer frock that a kind of structure is simple, clamping stability is good.
For achieving the above object, the utility model provides a kind of fracturing pump shoulder pole centralizer frock, comprise shoulder pole centralizer, pedestal, set bolt, described pedestal is disc, centre has through hole, outer ledge has a circle positioning convex, and described positioning convex thickness is not more than the thickness of the shoulder pole centralizer being in contact with it part; Described shoulder pole centralizer snaps in positioning convex, and end is pressed with briquetting, and set bolt is assembled into entirety through briquetting and pedestal.
Further, described briquetting is provided with briquetting projection.
Further, the diameter of described positioning convex is equal with shoulder pole centralizer length.
Further, the thickness of described briquetting projection is less than the thickness that shoulder pole centralizer exceeds the part of positioning convex.
The beneficial effects of the utility model are: the utility model structure is simple, low cost of manufacture; By using frock, the qualification rate of Related product is made to bring up to 95% by original 75%.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one one kinds of fracturing pump shoulder pole centralizer frock detailed description of the invention.
Fig. 2 is the left view of the utility model one one kinds of fracturing pump shoulder pole centralizer frock detailed description of the invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See Fig. 1 to Fig. 2, a kind of fracturing pump shoulder pole centralizer frock, comprise shoulder pole centralizer 1, pedestal 5, described pedestal 5 is disc, and centre has through hole 51, and described through hole 51 is for removing unnecessary material, alleviate pedestal deadweight, outer ledge has a circle positioning convex 52, and the diameter of described positioning convex 52 is equal with shoulder pole centralizer 1 length, and described positioning convex 52 thickness is not more than the thickness of the shoulder pole centralizer 1 being in contact with it part;
Described shoulder pole centralizer 1 snaps in positioning convex 52, and end is pressed with briquetting 2, and described briquetting 2 is provided with briquetting projection 21; The thickness of described briquetting projection 21 is less than the thickness that shoulder pole centralizer 1 exceeds the part of positioning convex 52;
Set bolt 3 is assembled into entirety through briquetting 2 and pedestal 5.
See Fig. 2, during gripping shoulder pole centralizer 1, first shoulder pole centralizer 1 is put into the primary importance A that positioning convex 52 departs from briquetting 2, then shoulder pole centralizer 1 is rotated until second place B, bolt 3 be tightened again by Work-sheet pressing, finally grab outside chuck 4 clamp base 5 with three of lathe and be fixed.
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.
