Description
Technical field
The present invention relates to a kind of electrode clamping instrument, specifically, relate to a kind of housing square edged orifice spark-erosion machining electrode clamping tool that is used for electrohydraulic servo valve.
Technical background
Be used for the used electro-hydraulic servo valve part valve pocket processing of electrohydraulic control system at present and have following defective:
Existing processing method: cut out profile by the line cutting earlier, stay a small amount of surplus, grind at last and guarantee designing requirement such as four sides or two coplane degrees, fineness, mainly finish by manpower.Roughing (line cutting) coplane degree instability, fineness are poor, and four corner angle circularity are bigger, the radius that is equivalent to the line cutting approximately, need finishing, bring very burden for fine finishining (grinding), workload strengthens, and causes inefficiency, processing cost increase, output to reduce, and needs to consume very big manpower work.
Summary of the invention
The objective of the invention is to overcome the defective of prior art and a kind of housing square edged orifice spark-erosion machining electrode clamping tool that is used for electrohydraulic servo valve is provided, its operability is good, the machining accuracy height, good reproducibility, long service life, significantly reduce the workload of processing, improved working (machining) efficiency greatly.
The technical scheme that realizes above-mentioned purpose is: is used for the housing square edged orifice spark-erosion machining electrode clamping tool of electrohydraulic servo valve, wherein, comprises a clamp body, at least one electrode and a pressing plate, wherein:
The top of described clamp body is the handle that is used for operating this clamping tool, and the bottom is the department of assembly that is used for assembling electrode, the lower surface of this department of assembly be provided with electrode shape coupling and have a groove with the electrode equal number;
Described electrode is vertically installed in the groove of clamp body department of assembly;
The front end face of described pressing plate by the department of assembly of a screw and clamp body is fixing compressing electrode, and is positioned by a straight pin in the department of assembly of clamp body.
Above-mentioned a kind of housing square edged orifice spark-erosion machining electrode clamping tool that is used for electrohydraulic servo valve, wherein, described straight pin is an elastic cylindrical pin.
Above-mentioned a kind of housing square edged orifice spark-erosion machining electrode clamping tool that is used for electrohydraulic servo valve, wherein, described screw is the hexagon socket head fillister head screw.
Above-mentioned a kind of housing square edged orifice spark-erosion machining electrode clamping tool that is used for electrohydraulic servo valve, wherein, described electrode is two, described groove is two.
The invention has the beneficial effects as follows: a kind of housing square edged orifice spark-erosion machining electrode clamping tool that is used for electrohydraulic servo valve of the present invention, electrode is contained in the clamp body, simple to operate, reduced the great amount of manpower work, reduced processing cost.
Description of drawings
Fig. 1 is the front view of electric discharging machining electrode clamping tool of the present invention;
Fig. 2 is the side view of electric discharging machining electrode clamping tool of the present invention;
Fig. 3 is the vertical view of electric discharging machining electrode clamping tool of the present invention;
Fig. 4 is the design of part figure of processed valve pocket of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1 to Fig. 3, there is shown the housing square edged orifice spark-erosion machining electrode clamping tool that is used for electrohydraulic servo valve of the present invention, it comprises a clamp body 4, at least one electrode and a pressing plate 2, is two electrodes 3 in the present embodiment, wherein:
The top of clamp body 4 is the handle 41 that is used for operating this clamping tool, the bottom is the department of assembly 42 that is used for assembling electrode, the lower surface of this department of assembly 42 be provided with electrode 3 form fit and have groove 421 with electrode 3 equal numbers, be two grooves in the present embodiment;
Electrode 3 is vertically installed in the groove 421 of clamp body department of assembly 42;
See also Fig. 4, design of part figure for the processed valve pocket of the present invention, square hole 6 and square hole 7 are hole to be processed among the figure, because the quality of square hole crudy is the quality of the properties of product of the whole electrohydraulic servo valve of influence directly, the required precision that is exactly square hole in addition is than higher, difficulty of processing is very big, and is therefore just very high to the requirement of the processing method of square hole and machining tool.
The electric discharging machining electrode clamping tool divides two kinds of roughing and fine finishining.Can divide the processing of thick, smart double piercing to rectangular window, but also to rectangular window divide thick, in, smart three perforation processing, decide by requirement on machining accuracy.
The housing square edged orifice spark machined valve pocket positioning tool of the electric discharging machining electrode clamping tool finished of assembling and electrohydraulic servo valve is used and carries out the valve pocket electric spark and wear square hole and process.The anchor clamps handle of electric discharging machining electrode clamping tool is carried out positioning and clamping on spark-erosion machine tool, treat to carry out electric-spark drilling with after the housing square edged orifice spark machined frock matrix of electrohydraulic servo valve cooperates centering.After treating that one group of rectangular opening 6,7 is put on, anchor clamps are changeed an angle, wear another group rectangular opening.If there is several prescriptions hole to wear, then can be simultaneously two groups pass, also can single group pass.
Above embodiment is only for the usefulness that the present invention is described, but not limiting the scope of the invention.Relevant those skilled in the art under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, and the technical scheme that all are equal to also should belong within the category of the present invention's protection, is limited by each claim.
