After the utility model has been taked such scheme, can be by the electrochemical corrosion that axle surface is produced, make the former hard axle Surface Creation oxide-film that loosen, recycle mechanical grinding tool and grind, removal surface film oxide, reaches polishing object.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model axial workpiece burnishing device.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.
As shown in Figure 1, a kind of axial workpiece burnishing device, comprise: lathe 1, lathe 1 is provided with the fixedly fixture of working shaft-like part 3 and the polishing machine 4 that axial workpiece is carried out to polishing, also be provided with electrochemical power source system 6, wherein, the anode assembly 2 of described electrochemical power source system is connected with the two ends of described working shaft-like part respectively with cathode assembly 5.
Described shaft fixing device comprises: be located at the fixture at working shaft-like part two ends, described working shaft-like part can be done axial rolling between described fixture.Described polishing machine is paper tape polishing machine.
Wherein, lathe mainly provides working shaft-like part corresponding rotary power, by its support and with suitable speed rotation, to carry out electrochemical reaction and machine glazed finish.
Electrochemical power source system, mainly provides the energy of electrochemical reaction, and it is anodal is connected with the electrolyte nozzle as negative electrode with, negative pole logical as being coupling of anode, and between cathode and anode, requirement is insulated.
Wherein, anode assembly mainly allows the axle lotus that becomes positively charged, and it is directly connected with axle, is connected by wire with positive source simultaneously, makes axle surface produce corrosion.
Cathode assembly, the nozzle that can be used as electrolyte is directly connected with power cathode again.
Wherein, described polishing machine adopts various precision abrasive band, and vibropolish is carried out in axle surface, removes the oxide-film that electrochemical reaction produces, and obtains the high-precision surface of axle.
In addition, this practical information can also provide and reclaim electrolyte in electrochemical reaction, and filters.
The utility model axle class processing unit (plant), the principle of main employing electrochemistry-precision optical machinery vibropolish is to using axial workpiece as anode, electrolyte is negative electrode, by the electrochemical corrosion that axle surface is produced, make the former hard axle Surface Creation oxide-film that loosens, utilize mechanical grinding tool to grind, removing surface film oxide, reaching polishing object.
Specifically, the main processes of axial workpiece burnishing device of the present utility model comprises electrochemical reaction and two parts of mechanical oscillation: electrochemical reaction is at polished axle Surface Creation oxide-film, the oxide-film that roller surface generates is removed in machinery reconditioning, makes its surface active; Repeatedly repeatedly, to obtain high-precision surface.Its surface roughness value can reach below Ra0.01 μ m, and its efficiency is the several times of first two finishing method.
Axial workpiece burnishing device processing technology requires axle in polishing first being processed efficiently, need process through grinding machine, goes whole defects on its surface, makes its surface roughness value within the scope of Ra ≈ 0.3 ~ 0.8 μ m, and requires evenly without grinding spiral lamination; Carry out polishing and add man-hour, after axle is winched on lathe and to be installed, by shift fork band moving axis, rotate, knife rest drives negative electrode assembly and paper tape polishing machine to process axle surface.This equipment, under the effect of the electrochemistry-mechanical devices such as electrochemical power source, electrolyte circulation system, anode assembly, cathode assembly, paper tape polishing machine, arrives lower surface roughness by axle Surface Machining, thereby reaches its surface finishing to the object of minute surface.
The utlity model has following advantage: 1) roughness precision is high, can reach below Ra0.01 μ m, machining shaft surface high conformity, without obvious machining marks; 2) efficiency is high, and it is higher more than 3 ~ 5 times than precision grinder and oilstone abrasive band polishing efficiency; 3) polishing front axle must first adopt grinding machine, surface roughness to reach between Ra ≈ 0.32 ~ 0.8 μ m, and surface can not defectiveness; 4) can remove some small grinding patterns; 5) this device is specially adapted to the polishing of the high rigidity axial workpiece of high-chromium material making; 6) low-cost, easy to operate, this equipment consists of lathe improvement, and small investment and technique are easily grasped, equipment is easy to operate.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
