Description

The fraise jig of a kind of machining piston valve hole use
Technical field
The utility model relates to jig, the fraise jig of especially a kind of machining piston valve hole use.
Background technology
In engine, in order to prevent that top land and valve from bumping against, and according to valve shape and position at corresponding several pits that process of top land, in industry, be conventionally referred to as valve hole.
Along with the further expansion of recent year, international heavy goods vehicle demand, Diesel engine is to high load capacity, high power, high strength future development, adopted high pressure common rail fuel injection system, many Valves Technology, this just has higher requirement to piston port hole position degree.
Summary of the invention
In order to guarantee position degree when machining piston valve is cheated, enhance productivity simultaneously, the utility model proposes the fraise jig of a kind of machining piston valve hole use.
For this reason, the technical solution of the utility model is: the fraise jig of a kind of machining piston valve hole use, comprise clamp bottom board, on clamp bottom board, be fixed with flange seat, flange seat rotational support has locating shaft, the outer axle journal of locating shaft coordinates with piston inner hole, the upper end of locating shaft is provided with piston locating piece, piston locating piece is provided with positioning guide hole, the cylindrical of flange seat is provided with locking nut, in the pilot hole of piston locating piece, be provided with and promote rod, it is characterized in that: in the rear end of flange seat, correspondence is provided with left locating dowel, right locating dowel, the inner side of right locating dowel is provided with guiding wedge, between guiding wedge and left locating dowel, form and promote excellent gathering sill, in right locating dowel, be also provided with and promote excellent thrust block, under use state, piston bush, on piston locating piece, is promoted pilot hole, the piston of rod through piston locating piece, by guiding wedge and left locating dowel location, guarantees the accurate location of piston.
Beneficial effect: the utility model, by increasing left locating dowel, right locating dowel, guarantees the accurate location of piston, has guaranteed the position degree in machining piston valve hole; Meanwhile, easy for installation, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
The specific embodiment
As shown in Fig. 1 Fig. 2, further describe the utility model as follows: the fraise jig of a kind of machining piston valve hole use, comprise clamp bottom board 1, on clamp bottom board, be fixed with flange seat 2, flange seat rotational support has locating shaft 4, the outer axle journal of locating shaft 4 coordinates with piston inner hole, the upper end of locating shaft is provided with piston locating piece 5, piston locating piece is provided with positioning guide hole, the cylindrical of flange seat is provided with locking nut 3, in the pilot hole of piston locating piece, be provided with and promote rod 10, in the rear end of flange seat correspondence, be provided with left locating dowel 6, right locating dowel 9, the inner side of right locating dowel is provided with guiding wedge 8, between guiding wedge 8 and left locating dowel 6, form and promote excellent gathering sill, in right locating dowel, be also provided with and promote excellent thrust block 7, under use state, piston bush, on piston locating piece, is promoted rod 10 through the hole on pilot hole, the piston of piston locating piece, by guiding wedge 8, locates with left locating dowel 6, guarantees the accurate location of piston.
Using method: promote rod 10 and automatically pin club head clamp-oned between left locating dowel 6 and guiding wedge 8 by guiding wedge 8, promote rod 10 head arrive the excellent thrust block 7(of distribution push away motionless till), to upper locking nut 3, can process.
