Summary of the invention
The purpose of this utility model is to provide a kind of location accurate, good reproducibility, the frock of triplicate blade impeller keyway processing easy to use.
For achieving the above object, the technical solution of the utility model is a kind of triplicate blade impeller keyway processing tool, comprises substrate and locating piece, and locating piece is fixedlyed connected with substrate, its innovative point is: locating piece is two, is on the working face that V-shape is fixedly connected on substrate.
A side plane of described substrate is a datum level, and the last plane of substrate is first working face, and lower plane is second working face, and two working faces are all perpendicular with described datum level.
It is perpendicular that described locating piece has first working face of described locating surface of locating surface and substrate, and be 60 ° of angles with the datum level of substrate and install, and the angle between the locating surface of two locating pieces is 60 °.
Have locating slot on first working face of described substrate, two side planes of locating slot parallel, and the datum level of two sides and substrate is perpendicular.
The locating surface of described two locating pieces is symmetry with respect to the split between two sides of the locating slot on the substrate.
Described locating piece and substrate are to be bolted to connection.
Also have taper pin to be located by connecting between described locating piece and the substrate.
The height of the locating surface of described placement plate is less than the height of locating piece.
After adopting the technical solution of the utility model, because the locating surface that is packed in two locating pieces on first working face of substrate is 60 ° of angles perpendicular to first working face 1 and with the datum level of substrate, and the angle between the locating surface of two locating pieces is 60 °, a triplicate blade impeller can be stuck between two locating pieces exactly like this, triplicate blade impeller for same size, as long as when processing keyway for the first time, frock is carried out centering, behind the location, batch machining very easily just, and the impeller keyway repeatable accuracy of processing is good.

The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing describes in further detail the utility model.
Referring to Fig. 1,2,3,4,5, a kind of triplicate blade impeller keyway processing tool comprises substrate 1 and locating piece 2, and locating piece 2 is fixedlyed connected with substrate 1, and its innovative point is: locating piece 2 is two, is on the first working face 1-2 that V-shape is fixedly connected on substrate 1.This structure is for the triplicate blade impeller of same dimensions, and when its outer contour was stuck between the locating surface 2-1 of two locating pieces 2, the position of its axis hole was fixed, and this has just guaranteed the repeatable accuracy of keyway processing.
Referring to Fig. 1,2,3, in order to guarantee the keyway machining accuracy, the precision of frock is very important, a side plane of described substrate 1 is datum level 1-1, the last plane of substrate 1 is the first working face 1-2, and lower plane is the second working face 1-3, and two working faces are all perpendicular with described datum level 1-1.When so just having guaranteed that frock is placed on the workbench, its working face parallels with workbench, described locating piece 2 has locating surface 2-1, the first working face 1-2 of described locating surface 2-1 and substrate 1 is perpendicular, and be 60 ° of angles installations with the datum level of substrate 1, the angle between the locating surface 2-1 of two locating pieces 2 is 60 °.Have locating slot 1-4 on the first working face 1-2 of described substrate 1, two side planes of locating slot 1-4 parallel, and the datum level 1-1 of two sides and substrate 1 is perpendicular.The locating surface 2-1 of described two locating pieces 2 is symmetry with respect to the split between two sides of the locating slot 1-4 on the substrate 1.After such frock is installed on the workbench of wire cutting machine, because the precision of frock internal structure is guaranteed, as long as carry out the datum level 1-1 of substrate 1 and the centering of locating slot 1-4 two sides, just guaranteed the precision of the locating surface 2-1 of locating piece 2, further guaranteed the positional precision on the online cutting workbench of trilobed wheel axis hole, Here it is certainly guarantees keyway machining accuracy and repeated prerequisite.
Because long-term processing makes the locating surface 2-1 of locating piece 2 wear and tear unavoidably, and influences impeller keyway machining accuracy, described locating piece 2 is to fixedly connected by bolt 1-5 with substrate 1.Between fixing for locating piece 2, described locating piece 2 and substrate 1 in addition taper pin 1-6 fixedly connected.Such structure, guarantee the locating piece firm position on the one hand, simultaneously can be easily locating piece 2 demolition from the substrate 1 be got off, 2-1 carries out grinding to its locating surface, and centering is installed again then, is fixed on the substrate, just can continue to use, therefore, this frock is not only easy to use, keeps in repair also very simple.
In order to reduce the wearing and tearing of frock as much as possible, described placement plate 2 the height of locating surface 2-1 less than the height of locating piece 2.When guaranteeing locating surface 2-1 positioning action, reduce the height of locating surface 2-1 like this, just reduced the wearing and tearing of workpiece frock.
Referring to Fig. 6, triplicate blade impeller keyway processing tool of the present utility model in use, at first frock is placed on the workbench of wire cutting machine, carry out the datum level 1-1 of substrate 1 and the location centering of locating slot 1-4, reach requirement if beat table look-up, frock can be fixed on the workbench, determine the position, two sides of locating slot 1-4 then according to the center line of wire cutting machine, when guaranteeing that triplicate blade impeller is stuck between two locating pieces 2 of frock, its axis hole center with respect to frock promptly in the center, the center that has guaranteed frock overlaps with the machining center of wire cutting machine, just can programme to lathe this moment, then the axis hole keyway of triplicate blade impeller has been processed, adding the outer surface that needs only man-hour triplicate blade impeller is close on the locating surface 2-1 of two locating pieces 2, very convenient, if change the specification of triplicate blade impeller, because the angle tangent with the cambered surface of the wide face of triplicate blade impeller outside opinion is constant, so can change frock, as long as lathe is reprogramed, can process the triplicate blade impeller keyway of different size.
Triplicate blade impeller keyway processing tool of the present utility model is easy to use, utilizes the triplicate blade impeller keyway precision height of the utility model processing, and good reproducibility is specially adapted to multi-disc, the processing of combination type blade wheel keyway.
