Description
Technical field
The utility model belongs to machining equipment technical field, relates in particular to a kind of high-pressure gear pump postoperculum end face fixer for machining.
Background technology
The bonnet of high-pressure gear pump need to be fixed on blank and on the operating desk of machining center, carry out fine finishining and obtain, as flatness processing of end face etc.Due to its shape of bonnet of high-pressure gear pump irregular, therefore be difficult on the operating desk of the work in-process heart fixingly, this has brought difficulty for the processing of its end face.
Utility model content
The utility model provides the high-pressure gear pump postoperculum end face fixer for machining of a kind of simple in structure, simple operation, good fixing effect for solving the technical problem existing in known technology.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: high-pressure gear pump postoperculum end face fixer for machining comprises that two ends are with the base plate of connecting hole; On base plate, be provided with eight contour columns, wherein the position of four columns be opened in the pin-and-hole on installed surface inside pump postoperculum workpiece and align, at the top of these four columns, be provided with the alignment pin coordinating with each pin-and-hole, the position of other four columns and the installing hole being opened on pump postoperculum workpiece align, and in the top center of these four columns, are provided with screwed hole.
Advantage of the present utility model and good effect are: owing to having adopted above-mentioned design, the utility model is simple in structure.Pump postoperculum workpiece is placed on each column, and each alignment pin inserts inside workpiece in each pin-and-hole on installed surface, penetrates a plurality of trip bolts and be tightened in the screwed hole of column workpiece is fixed from outside, and good fixing effect, positioning precision are high.
Accompanying drawing explanation
Fig. 1 is the plan structure schematic diagram of use state of the present utility model;
Fig. 2 be in Fig. 1 A-A to cutaway view.
In figure: 1, base plate; 2, connecting hole; 3, trip bolt; 4, pump postoperculum workpiece; 5, alignment pin; 6, column.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1 and Fig. 2, the utility model comprises that two ends are with the base plate 1 of connecting hole 2, and whole device is fixed with the operating desk of machining center by the connecting hole 2 of base plate 1 together with workpiece.
On base plate 1, be provided with eight contour columns 6.Wherein the position of four columns 6 aligns with the pin-and-hole being opened on pump postoperculum workpiece 4 inner side installed surfaces, at the top of these four columns 6, be provided with the alignment pin 5 coordinating with each pin-and-hole, the position of other four columns 6 and the installing hole being opened on pump postoperculum workpiece 4 align, and in the top center of these four columns 6, are provided with screwed hole.
Using method: pump postoperculum workpiece 4 is placed on each column 6, each alignment pin 5 inserts inside workpiece in each pin-and-hole on installed surface, penetrates a plurality of trip bolts 3 and be tightened in the screwed hole of column 6 workpiece is fixed from outside.Afterwards whole device is fixed to together with workpiece on the processing platform of machining center, carries out end face processing.
