Abstract
The utility model discloses a sprayer clamp plate bearing structure, including supporting the part, it is equipped with the supporting plane to support the part top, the supporting plane on be equipped with with the counter bore of the fulcrum ball facial features adaptation of sprayer clamp plate rear end. The utility model discloses simple structure, reliable for support the sphere to sprayer clamp plate rear end and retrain, prevent that the rotation of sprayer clamp plate from leading to the fact the extrusion to the sprayer, effectively protect the sprayer, realize installing fast the sprayer.
Description
Technical field
This utility model relates to a kind of engine fittings, more specifically, it relates to a kind of injector plate supporting construction.
Background technology
During the assembling of Diesel engine, fuel injector is typically fixed by pressing plate.When installing fuel injector, in order to make fuel injector uniform force, stress deformation outside preventing fuel injector from producing design, the injector plate rear end strong point is typically designed to spherical (shown in Fig. 5), so that injector plate can rotate freely in certain scope, it is to avoid because Planar Mechanisms causes the extra stress of fuel injector to be damaged.During fuel injector fastening bolt tightens, effect because of frictional force, injector plate will be by a turning moment, due in current electromotor, cylinder cap or the bolt etc. that support sphere-contact with injector plate rear end support part, and its contact surface is a plane (shown in Fig. 5), it is impossible to provide the countertorque enough resisting its turning moment, thus cause fuel injector by a side force, cause the problem that fuel injector internal precision part deformation, clamping stagnation etc. affect fuel injector performance.
Utility model content
The technical problems to be solved in the utility model is the above-mentioned deficiency for prior art, it is provided that a kind of simple in construction, installation reliably, can effectively prevent the injector plate supporting construction that injector plate rotates.
The technical solution of the utility model is such that a kind of injector plate supporting construction, and including supporting part, described support part top is provided with supporting plane, and described supporting plane is provided with the counterbore supporting sphere adaptation with injector plate rear end.
As improving further, described counterbore is that porch is rounded, and bottom is narrowed in the cone shaped countersink of a fulcrum.
Further, described counterbore porch radius is more than the radius supporting sphere of injector plate rear end, and the support sphere of injector plate rear end can be retrained by described counterbore along depth direction.
Further, described counterbore is located along the same line with the axial line of mounting hole of oil sprayer, fastening bolt holes.
Beneficial effect
Injector plate supporting construction of the present utility model is simple, reliably, by arranging cone shaped countersink on the supporting plane supporting part, for location and installation injector plate, there is provided a countertorque for injector plate, effectively prevent injector plate from rotating, fuel injector is caused extruding；This cone shaped countersink porch radius supports the radius of sphere more than injector plate rear end, it is ensured that fuel injector still can rotate freely in required scope, contributes to regulating injector plate and positions fuel injector, it is achieved Fast Installation fuel injector.

Detailed description of the invention
This utility model is described further by the specific embodiment in below in conjunction with the accompanying drawings.
Refering to Fig. 1-4, a kind of injector plate supporting construction of the present utility model, including supporting part 1, this support part 1 top is provided with supporting plane 11, supporting plane 11 is provided with the counterbore 12 supporting sphere 2 adaptation with injector plate 5 rear end, this counterbore 12 is that porch is rounded, and bottom is narrowed in the cone shaped countersink of a fulcrum；Counterbore 12 porch radius is more than the radius supporting sphere 2 of injector plate 5 rear end simultaneously, it is ensured that injector plate 5 is still freely rotatable when malcompression, it is simple to fuel injector 3 is positioned by regulation injector plate 5；And the support sphere 2 of injector plate 5 rear end can be retrained by this counterbore 12 along depth direction, during fastening bolt 4 tightens, prevent injector plate 5 from rotating.This counterbore 12 is located along the same line with the axial line of mounting hole of oil sprayer 13, fastening bolt holes 14, make the support sphere 2 of injector plate 5 rear end just to this counterbore 12, contribute to the Fast Installation of fuel injector 3.
During use, one end of injector plate 5 is inserted in fuel injector 3, suitable adjustment injector plate 5, the sphere 2 that supports making injector plate 5 rear end falls in the counterbore 12 supported on part 1, then tightens trip bolt 4, during fastening bolt 4 compresses, the sphere 2 that supports of injector plate 5 rear end contacts extruding with the counterbore 12 in support part 1, thus produce a moment contrary with injector plate 5 turning moment, prevent injector plate 5 from rotating, fuel injector 3 is damaged.
Above-described is only preferred implementation of the present utility model, should be understood that for a person skilled in the art, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement, these are all without affecting effect and the practical applicability that this utility model is implemented.
