In this way, the utility model discloses top thickness chi when coming the rough machining of accurate control ring carrier piston by the locating piece that floats with set screw, and the wall thickness of piston skirt poor, for the smart manufacturing procedure of subsequent piston provides reliable technology benchmark, lifting surface area when having strengthened that ring carrier formula traffic jam alive cuts man -hour has reduced the machining stress, has saved cutter and frock expense, has reduced manufacturing cost, effectual assurance piston top thickness size and piston skirt wall thickness are poor, have improved the processingquality of piston.
Description
Technical field
The utility model relates to edge ring type Piston Machining device, particularly relates to the rough turn processing tool of a kind of edge ring type outside piston.
Background technology
One in edge ring type piston type piston.As everyone knows, piston be by be casting form, after original ring-mounted piston has been cast, its end face is not processed, cannot ensure the top thickness size of piston, so, blank top thickness scale error size directly has influence on the machining accuracy of finish turning piston seam operation and piston cavity size, cause finish turning to inlay the upper and lower wall unevenness of ring recess even, time serious, cause product rejection.Simultaneously because end face blank is not processed, cause later process end face allowance too large, to making, frock, tool wear are serious, production cost is increased, simultaneously because allowance is large, the machining stress produced can not get good release, and cause Product processing to be out of shape serious, crudy can not be guaranteed.
Utility model content
The technical problem that the utility model mainly solves is to provide the rough turn processing tool of a kind of edge ring type outside piston, increase lifting surface area during edge ring type piston turning, reduce machining stress, also mitigate the fine finishining burden of edge ring type piston simultaneously, save cutter and frock expense, reduce production cost, effective guarantee piston top thickness size and piston skirt Wall-Thickness Difference, improve the crudy of piston.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of edge ring type outside piston rough turn processing tool, comprise driver plate, mandrel, float locating piece, spring and dog screw, described mandrel pierces into from one end, driver plate center, pass from other one end, described floating locating piece is the round sleeve structure with tapered step surface, described round sleeve is sleeved on mandrel one end and step surface is connected with driver plate, described spring is arranged on round sleeve inside, and described dog screw is arranged on end face of mandrel.
In the utility model preferred embodiments, described driver plate, mandrel, float locating piece, Compress Spring and dog screw are same center line.
In the utility model preferred embodiments, described driver plate comprises disk end and boss end, and described disk end end face is provided with concave groove.
In the utility model preferred embodiments, described mandrel penetrates from boss end, passes from disk end, and mandrel penetrate end locked by screw and driver plate.
In the utility model preferred embodiments, the rough turn processing tool of described edge ring type outside piston also comprises pagoda of bowls.
The beneficial effects of the utility model are: the rough turn processing tool of the utility model one edge ring type outside piston, increase lifting surface area during edge ring type piston turning, reduce machining stress, save cutter and frock expense, reduce production cost, effective guarantee piston top thickness size and piston skirt Wall-Thickness Difference, improve the crudy of piston.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of novel edge ring type outside piston of the present utility model rough turn processing tool one preferred embodiment.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment provides following technical scheme.
The rough turn processing tool of a kind of edge ring type outside piston, comprise driver plate 1, mandrel 2, float locating piece 3, spring 4 and dog screw 5, described mandrel 2 pierces into from one end, driver plate 1 center, pass from other one end, described floating locating piece 3 is the round sleeve structure with tapered step surface 31, described round sleeve is sleeved on mandrel 2 one end and step surface 31 is connected with driver plate 1, and described spring 4 is arranged on round sleeve inside, and described dog screw 5 is arranged on mandrel 2 end face.
In above-mentioned, dog screw 5 is fixed on mandrel 2, the uniformity of top thickness size during guarantee piston 8 roughing, and the locating piece 3 that floats is contacted with piston 8 skirt section by tapered step surface 31, the uniformity of skirt section Wall-Thickness Difference during guarantee ring-mounted piston roughing.During blank casting, piston cavity depth dimensions, not in same plane, makes floating locating piece 3 fix with piston 8 skirt section inner chamber by the elasticity of spring 4 simultaneously, fixing reliable, accurate positioning.
Further, described driver plate 1, mandrel 2, locating piece 3, Compress Spring 4 and the dog screw 5 that float are same center line, ensure piston centre and processing tool coaxial line.Realize the unifying datum principle adding man-hour, positioning datum is piston 8 inner chamber top, and measuring basis is equally also piston 8 inner chamber top, decreases the mismachining tolerance produced due to benchmark disunity.
Further, described driver plate 1 comprises disk end 12 and boss end 11, described disk end 12 end face is provided with concave groove 13, the side of concave groove 13 is stuck in tapered step surface 31 and is connected with floating locating piece 3, mandrel 2 penetrates from boss end 11, pass from disk end 12, and mandrel 2 penetrates end by screw 6 and driver plate 3 locking positioning.
Further, the rough turn processing tool of described edge ring type outside piston also comprises pagoda of bowls 7, and pagoda of bowls 7 and driver plate are same center, be separately fixed at the rotating disk of vehicle window and afterbody top on, piston 8 is arranged between pagoda of bowls 7 and floating locating piece.
The beneficial effects of the utility model are:
1, the stressed skirt section thin from structure of piston becomes intensity and the good top of rigidity, and processing stressing conditions is greatly taken on a new look, and machining stress greatly reduces, and improves the crudy of product;
2, because piston-top surface during roughing eliminates a large amount of allowance, save cutter and frock expense, reduce production cost;
3, ensure top thickness size and piston skirt Wall-Thickness Difference, the crudy of ring-mounted piston is greatly taken on a new look.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
