Abstract
The utility model relates to a drill jig which comprises a drill jig body. The drill jig body is in a fan shape, at least two die hole rows are formed in the drill jig body, and each die hole row is provided with a plurality of die holes arrayed in the radial direction of the drill jig body. The fan-shaped drill jig body is used for alternately machining a plurality of sets of connecting holes in the circumferential direction in a grouping mode, self-weight of the drill jig can be reduced, cost is saved, conveying difficulty is reduced, the size is small, and deformation cannot easily occur.
Description
Technical field
The utility model relates to a kind of mould of machining hole, particularly a kind of drill jig.
Background technology
existing Large Hydroelectric Set, usually adopting the runner-plate pump circulatory system and thrust bearing is partly the structure that adopts the pushing force foundation ring to separate with lower bearing bracket, when lower bearing bracket is installed, the machine that normally lower bearing bracket hung in is cheated and is put off at lower bearing bracket and reserves on the concrete of hole, and after the support ring end face that is used for support thrust bearing on lower bearing bracket is transferred to level, reinforce and build, enter the installation procedure of thrust bearing thereafter, wherein, thrust bearing is arranged in lower bearing bracket centerbody oil groove by the pushing force foundation ring, the Main Function of pushing force foundation ring is be used to supporting whole thrust bearing weight, and as the reference platform of installed thrust bearing remaining part.
The support ring end face of pushing force foundation ring and lower bearing bracket cooperatively interacts, and by several along circumferential equally distributed and position relationship one to one the connection holes construction bolt closing, but, because the diameter of above-mentioned pushing force foundation ring and lower bearing bracket support ring is larger, adopt the processing of drill jig method, the required drill jig of using has that diameter is large, the drill jig deadweight is heavier, and the weak points such as deformation easily occur drill jig.
The utility model content
The technical problems to be solved in the utility model is to overcome the above-mentioned deficiency of prior art, provides a kind of size to simplify, and from heavy and light, self is difficult for occuring the drill jig of deformation.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
A kind of drill jig comprises the drill jig body, and described drill jig body is fan-shaped, is provided with at least two row nib row on described drill jig body, and described each nib row include several along the nib of the arranged radially of drill jig body.
Preferably, comprise four row nib row on described drill jig body.
Preferably, each nib lists and includes three nibs.
Preferably, the circumferential angle between described adjacent two row nib row is 15 °～17 °.
Preferably, be provided with lightening hole on described drill jig body, described lightening hole is arranged between adjacent two row nib row, and described lightening hole runs through the drill jig body along the thickness direction of drill jig body.
Preferably, the radially inner side of described drill jig body is provided with male half coupling.
Preferably, the external diameter of described male half coupling is identical with the interior ring diameter of work piece.
Preferably, the thickness of described drill jig body is 40mm～60mm.
Compared with prior art, the beneficial effects of the utility model are: adopt fan-shaped drill jig, available alternately to the mode of circumferential some groups of connection holes grouping Processing, alternative existing full circle shape Drilling Jig Structure, can alleviate the drill jig deadweight, save cost, reduce transport difficulty, size is simplified and is difficult for deformation.
