Abstract
The utility model discloses a fixture preventing carbon from depositing at a water opening. The fixture comprises a fixture body, and is characterized in that the top of the fixture body is provided with a groove used for accommodating workpieces; the bottom of the groove is provided with an externally connected waterway; and the externally connected waterway is connected with a water inlet through a pipeline. With the adoption of the fixture preventing the carbon from depositing at the water opening, the workpieces can be washed in an electrical discharge machining (EDM) process, so that the carbon depositing phenomenon is effectively avoided.
Description
Technical field
the utility model relates to a kind of fixture, and especially a kind of mouth of a river prevents the carbon distribution fixture.
Background technology
electrical discharge machining (EDM) is mainly used in ,Jian chamber, the part hole processing in work piece production, has become one of manufacturing leading processing method of workpiece, has promoted the technological progress of die industry.Principle is instantaneous concentrated a large amount of heat energy in the micro-channel of electric discharge, temperature can be up to more than 10,000 degrees centigrade, pressure also has sharply variation, thereby make the metal material of the local trace of this point working surface melt at once, gasify, and explosion type be splashed in working solution, condensation rapidly, the metal particle of formation solid, taken away by working solution.At this moment just stay next small pit vestige on surface of the work, of short duration the resting of discharging, between two electrodes, working solution recovers state of insulation.And then, another some place that next pulse voltage approaches relatively at two electrodes again punctures, and produces spark discharge, repeats said process.Like this, although the amount of metal of each pulsed discharge ablation is few, because per second has thousands of subpulse discharge process, just the more metal of energy ablation, have certain productivity ratio.Yet during the deep mouth of a river of electrical discharge machining (EDM), because the mouth of a river is darker, be easy to produce the carbon distribution phenomenon, will cause like this workpiece reprocess or reform.
Summary of the invention
the utility model purpose is: provide a kind of mouth of a river simple in structure to prevent the carbon distribution fixture, can be rinsed workpiece in the electrical discharge machining (EDM) process, effectively avoid the generation of carbon distribution phenomenon.
the technical solution of the utility model is: a kind of mouth of a river prevents the carbon distribution fixture, comprise chuck body, it is characterized in that, described chuck body top is provided with the groove for place work piece, be provided with external water route at described bottom portion of groove, described external water route connects water inlet by pipeline.
preferably, described bottom portion of groove is provided with at least 2 external water routes.
preferably, described chuck body side is provided with cylindrical hole.
during due to the deep mouth of a river of electrical discharge machining (EDM), because the mouth of a river is darker, be easy to occur the carbon distribution phenomenon, so at first the workpiece of needs processing is fixed in the groove of described chuck body, in the electrical discharge machining (EDM) process, rinse to the workpiece water filling by external water route, can effectively avoid the generation of carbon distribution phenomenon.
the utility model has the advantages that:
in the electrical discharge machining (EDM) process, by external water route, to the workpiece water filling, rinse, can effectively avoid the generation of carbon distribution phenomenon.
The accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the utility model structural representation;
fig. 2 is the inner external water route of the utility model perspective view;
wherein: 1 chuck body, 2 grooves, 3 external water routes, 4 water inlets, 5 cylindrical holes, 6 workpiece.
The specific embodiment
embodiment: with reference to Fig. 1, shown in 2, a kind of mouth of a river prevents the carbon distribution fixture, comprise chuck body 1, chuck body 1 top is provided with the groove 2 for place work piece 6, be provided with 5 external water routes 3 in groove 2 bottoms, external water route 3 connects water inlet 4 by pipeline, during due to the deep mouth of a river of electrical discharge machining (EDM), because the mouth of a river is darker, be easy to produce the carbon distribution phenomenon, so at first the workpiece of needs processing is fixed in the groove 2 of described chuck body 1, in the electrical discharge machining (EDM) process, by external water route 3, to the workpiece water filling, rinse, can effectively avoid the generation of carbon distribution.Chuck body 1 side is provided with cylindrical hole 5, contributes to cleaning liquid to discharge as early as possible.
above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (3)
1. a mouth of a river prevents the carbon distribution fixture, comprises chuck body, it is characterized in that, described chuck body top is provided with the groove for place work piece, at described bottom portion of groove, is provided with external water route, and described external water route connects water inlet by pipeline.
2. the mouth of a river according to claim 1 prevents the carbon distribution fixture, it is characterized in that, described bottom portion of groove is provided with at least 2 external water routes.
