Abstract
The utility model provides an electric spark processing side aiming device, which is characterized in that: a mirror holder is fixedly connected with one side surface of a machine tool main shaft, the mirror holder and a microscope are fixedly connected with an outer sleeve, the microscope is paralleled to the machine tool main shaft, and the lower end of the machine tool main shaft is fixedly connected with an electrode. By adopting the electric spark processing side aiming device, the installation error caused by the secondary installation and clamping can be avoided, and the aiming error can be controlled within 2 micrometers, so the electric spark processing precision can be doubled.
Description
Technical field
The utility model belongs to the spark erosion technique field, is specifically related to a kind of spark machined side collimation device.
Background technology
At present, known spark machined sighting device is nothing more than dual mode, and a kind of is to utilize the contact perception, and another kind is with the aiming of centering microscope.Utilize contact perception aiming, when tool-electrode is very thin, electrode directly when having only several microns, very easily bumps curved.And the taper shank tool-electrode that need change the outfit during with centering microscope aiming work, general error is bigger.
Spark machined sighting device commonly used generally is on same main shaft, to adopt centering microscope aiming workpiece earlier, unloads the centering microscope taper shank tool-electrode that changes the outfit then and processes.Owing to adopt the secondary clamping generally can produce the error about 20 microns.Can satisfy specification requirement for common spark machined; But the specification requirement error of the microbarn of high-tech sector processing is about 5 microns, and the precision of spark machined sighting device commonly used is apart from requiring gap bigger.
Summary of the invention
The settled technical problem of the utility model provides a kind of spark machined side collimation device.
Mirror holder in the spark machined side collimation device of the utility model is fixedly connected with a side of machine tool chief axis, and mirror holder, microscope are fixedly connected with overcoat, and microscope is parallel with machine tool chief axis, and the lower end of machine tool chief axis is fixedly connected with electrode.
Adopt the spark machined side collimation device of the utility model, can save the alignment error that machining tool secondary clamping brings, can collimating fault be controlled at about 2 microns, obviously improved machining accuracy.The spark machined side collimation device of the utility model is applicable to the spark machined of minute aperture superelevation positional precision.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the spark machined side collimation device of the utility model.
Among the figure, 1. machine tool chief axis 2. mirror holders 3. screws 4. microscopes 5. overcoats 6. electrodes.
The specific embodiment
Fig. 1 is the structural representation of the spark machined side collimation device of the utility model; In Fig. 1; Mirror holder 2 in the spark machined side collimation device of the utility model is fixedly connected with a side of machine tool chief axis 1 through screw 3; Mirror holder 2, microscope 4 are fixedly connected with overcoat 5, and microscope 4 is parallel with machine tool chief axis 1, and the lower end of machine tool chief axis 1 is fixedly connected with electrode 6.
Be respectively arranged with corresponding groove on mirror holder 2, the overcoat 5 and be used for fixing microscope 4.Mirror holder 2, overcoat 5 adopt the light aluminum alloy material respectively.Microscope 4 employing commercially available prod, 50 times of multiplication factors also can adopt other multiple as required.
In order to overcome the alignment error that existing electric machining sighting device exists the secondary clamping to bring, the utility model adopts side-mounted fixedly microscope aiming.On test specimen, process any hole earlier during work with electrode; Electrode does not unload; Lathe zero clearing simultaneously; Move the xy axle of lathe then, any central point of hole of aiming electrode processing also writes down the xy axis values, has obtained spark machined side sighting device center and machine tool chief axis center (tool-electrode center) fixed numbers X Y thus.According to these data X Y; When processing superhigh precision minute aperture, lathe and punching are moved according to xy axle fixed numbers X Y then in aiming minute aperture to be processed center earlier; So; Saved the alignment error that the secondary clamping brings, can collimating fault be controlled at 2 microns, made machining accuracy improve several times.
