Description
Technical field
The utility model relates to the tool for mechanical machining field, particularly relates to a kind of for the electrolytic polishing instrument to the processing of imperfect hole.
Background technology
Difficult processing metal refers to that machinability is poor, is difficult to carry out the metal of machining, such as high strength steel, high temperature alloy and titanium alloy etc.Main manifestations is: tool wear is serious in the process, and is difficult to obtain desired surface roughness and suface processing quality.
Part with imperfect hole refers to that certain hole on the part do not seal, that is the part in this hole opens wide, and therefore utilizes conventional machining process to process the internal circular surfaces of difficult processing metal.If grinding technics is processed its internal circular surfaces by hand, not only the amount of labour is larger, clamp structure is complicated, cost is higher, and working (machining) efficiency is extremely low, therefore can only process single-piece or parts in small batch, defectives such as " subsiding " very easily appears in the part after the processing in indentation, there simultaneously, so that can affect the serviceability of part.
Summary of the invention
The technical problem that the utility model mainly solves provides a kind of for the electrolytic polishing instrument to the processing of imperfect hole, and it is simple in structure, and is with low cost, easily make, flexible and convenient operation, and working (machining) efficiency is high, processing effect is good, is fit to very much the processing to part in enormous quantities.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of for the electrolytic polishing instrument to the processing of imperfect hole, should be used for the electrolytic polishing instrument of imperfect hole processing is comprised hole processing grinding head, hole processing grinding head is installed on the rotating shaft of motor, be connected with electrolyte mozzle and carbon brush on the hollow tube connector of hole processing grinding head, be connected with wire on the carbon brush; Described hole processing grinding head comprises circular cylindrical cavity, and the circular cylindrical cavity upper end is equipped with the hollow tube connector of connection, and the hollow tube connector is fixedly connected with the rotating shaft of motor, and the circular cylindrical cavity periphery is equipped with to grind by dead ring uses nonwoven; The circular cylindrical cavity periphery is provided with a plurality of electrolyte apertures that are interspersed, and the position of the corresponding electrolyte aperture of nonwoven also is provided with aperture;
Preferably, the making material of described circular cylindrical cavity is red copper;
Preferably, described hollow tube connector is stainless steel material;
Preferably, the circular cylindrical cavity bottom of described hole processing grinding head is stainless steel material.
The beneficial effects of the utility model are: the utility model is a kind of for the electrolytic polishing instrument to the processing of imperfect hole, it is simple in structure, with low cost, easily make, flexible and convenient operation, defectives such as " subsiding " can not appear in the part after the processing in indentation, there, can satisfy the serviceability of part fully, can give full play to again simultaneously the advantage of electrochemistry and mechanical lapping combination process, working (machining) efficiency is improved greatly, suface processing quality is improved greatly, is fit to very much the processing to part in enormous quantities.
Description of drawings
Fig. 1 is the structural representation of a kind of electrolytic polishing instrument for imperfect hole is processed of the utility model;
Fig. 2 is the dead ring schematic diagram of a kind of electrolytic polishing instrument for imperfect hole is processed of the utility model.
The specific embodiment
Preferred embodiment is described in detail to the utility model below in conjunction with accompanying drawing, thereby so that the advantage of utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of for the electrolytic polishing instrument to the processing of imperfect hole, should be used for the electrolytic polishing instrument of imperfect hole processing is comprised hole processing grinding head 3, hole processing grinding head 3 is installed on the rotating shaft of motor 1, be connected with electrolyte mozzle 2 and carbon brush 8 on the hollow tube connector 32 of hole processing grinding head 3, be connected with wire 7 on the carbon brush 8; Described hole processing grinding head 3 comprises circular cylindrical cavity 31, circular cylindrical cavity 31 upper ends are equipped with the hollow tube connector 32 of connection, hollow tube connector 32 is fixedly connected with the rotating shaft of motor 1, and circular cylindrical cavity 31 peripheries are equipped with by dead ring 4 and grind with nonwoven 5; Circular cylindrical cavity 3 peripheries are provided with a plurality of electrolyte apertures 33 that are interspersed, and the position of nonwoven 5 corresponding electrolyte apertures 33 also is provided with aperture 51; The making material of described circular cylindrical cavity 31 is red copper; Described hollow tube connector 32 is stainless steel material; The circular cylindrical cavity bottom 6 of described hole processing grinding head 3 is stainless steel material.
A kind of operation principle of the electrolytic polishing instrument for imperfect hole is processed is: its chemistry is in electrochemistry processing with the mechanical lapping combination process, utilize mechanical milling tech to accelerate the removal of surface of the work passivating film, thereby working (machining) efficiency is greatly improved, and mechanical abrasive action is conducive to again the leveling of surface of the work simultaneously.The abrasive material electrochemistry that flows and mechanical lapping combination process are that superfine abrasive material (micron or nanoscale) evenly is suspended in the electrolyte, and the movement locus of work in-process abrasive material is more disorderly, so this processing technology more easily obtains needed suface processing quality.
Before processing, the positive pole that at first part is connected dc source, hole processing grinding head 3 is connected to the negative pole of dc source by carbon brush 8 and wire 7, then electrolyte mozzle 2 is connected, the electrolyte that contains the finite concentration abrasive material can arrive machining area by the aperture on hole processing grinding head 3 and the nonwoven 5, then connect dc source, can implement the processing to part, in process, with certain speed slow mobile hole processing grinding head 3 up and down, not only good processing effect can be obtained, and working (machining) efficiency can be significantly improved.If the zone of required processing exceeds the area that nonwoven 5 covers on the processing grinding head 3 of hole on the workpiece, can use binding agent that nonwoven 5 is bonded on the hole processing grinding head 3 this moment, enforcement adds man-hour with certain speed slow mobile hole processing grinding head 3 up and down, can finish quickly and easily the processing to the whole machining area of workpiece.
The utility model is a kind of for the electrolytic polishing instrument to the processing of imperfect hole, it is simple in structure, with low cost, easily make flexible and convenient operation, defectives such as " subsiding " can not appear in the part after the processing in indentation, there, can satisfy the serviceability of part fully, can give full play to again the advantage of electrochemistry and mechanical lapping combination process simultaneously, working (machining) efficiency is improved greatly, suface processing quality is improved greatly, is fit to very much the processing to part in enormous quantities.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
