Description
Technical field:
The utility model relates to a kind of spark machine workbench, particularly a kind of special spark machine workbench, new spark machined mode.
Background technology:
Existing spark machine work all is to carry out work by electrode axis to moving, because grinding tool slug press endoporus circularity and coaxiality error, make copper electrode loss in discharge extremely inhomogeneous, the axiality and the circularity front end that can't guarantee bistrique cylindrical and endoporus like this consume much larger than the rear end, and therefore the endoporus of conventional spark-erosion machine tool and processing method processing can produce tapering; Need repeatedly finishing or change copper electrode for reducing tapering, cause the waste of electrode material.
Summary of the invention:
The spark machine workbench that the utility model is invented in order to solve above-mentioned prior art problem just.
The utility model is realized by following technological means:
A kind of spark machine workbench comprises and transforms back electric spark equipment and the workbench that rotatable chuck is housed.The workpiece setting that needs spark machined is between workbench that rotatable chuck is housed and electric spark equipment.
Described spark erosion equipment includes the reducing motor and the rotatable electrode tip holder of adjustable speed, and reducing motor links to each other with rotatable spark machine electrode tip holder by belt; Described spark machine includes the electrode on rotatable spark machine electrode tip holder and the spark machine electrode, and the spark machine electrode tip holder also links to each other with the spark machine main shaft, can make movement in vertical direction.
Described workbench includes rotatable chuck, worm-and-wheel gear and base plate electric machine, and base plate electric machine is connected with worm screw by chain, and the turbine and worm transmission mechanism is connected with rotary chuck, and workpiece places on the rotary chuck.
The worm screw of described turbine and worm transmission mechanism is connected with the chassis reducing motor by chain, sprocket wheel, and worm screw drives the turbine rotation, and rotary chuck is arranged on the turbine.
The utility model is compared with prior art and is had the following advantages:
1, enlarged the range of work of this equipment, can not only process endoporus, all right processing excircles;
2, avoided because of the inevitably low precision of blank, made electrode produce inhomogeneous consumption and the hole taper and the out-of-roundness that produce;
3, rotate the spark machined mode mutually, avoid traditional handicraft to need artificial inaccuracy and individual difference the center.Its axiality certainly only is decided by the making precision of chuck, and this can use machining to obtain degree of precision, and can keep the long period precision stability, makes the product axiality have further and guarantees.
4, the little endoporus of diamond (￠ is below 15) uses traditional emery wheel internal grinder processing, and is possible in theory, and because of little silicon carbide grinding wheel consumption is too fast, is infeasible in actual job, and endoporus is more little, impossible more.Through comparative measurements import endoporus is the hydrogen bronze diamond grinding head of ￠ 10, coaxiality error more than 0.2mm, and through the like product coaxiality error of this spark machined less than 0.05mm (containing the influence of diamond salient point).
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model Working table structure schematic diagram;
Identifier declaration among the figure: motor 1, belt pulley 2, electrode base 3, electrode 4, workpiece 5, rotary chuck 6, base plate electric machine 7, sprocket wheel 8, chain 9, turbine and worm mechanism 10, scroll bar 10-1, turbine 10-2, spark machine main shaft 11, connecting plate 12.
Specific embodiment:
As shown in Figure 1, a kind of spark machine workbench is divided into electric spark part and workbench part, and the electric spark part mainly is made of spark machine and motor 1, and motor 1 is provided with a belt, and belt also is connected on the belt pulley 2 of electrode tip holder.Belt drove electrode 4 when motor 1 rotated, synchronously rotation.Electrode 4 is contained in the lower end of electrode tip holder 3, fits with needs electric spark workpiece 5.And motor 1 utilizes connecting plate 12 and spark machine main shaft 11 to join
As shown in Figure 1 and Figure 2, workbench partly includes base plate electric machine 7 and rotary chuck 6, and rotary chuck 6 is placed on the turbine 10-2, and turbine 10-2 drives by worm screw 10-1.Be connected to the chain 9 of sprocket wheel 8 and base plate electric machine 7 interlocks on the worm screw 10-1.When base plate electric machine 7 rotated, the turbine and worm transmission mechanism driven rotary that rotary chuck 6 is made of turbine 10-2 worm screw 10-1 made the workpiece 5 that is positioned on the rotary chuck 6 rotate together.
Workpiece direction of rotation on the workbench is opposite with spark machine electrode direction of rotation, when electrode and workpiece gap reach less than discharging gap, produce spark discharge, workpiece is produced ablation, like this when spark machine is worked, workpiece and electrode are by keeping appropriate gap, in constantly reverse rotation flashing discharge mutually, when discharge current in wholecircle Zhou Jiagong when establishing electric current, electrode and workpiece intercropping move radially (it is big that interior hole dimension becomes), hole dimension reaches the setting size in workpiece, and electric spark is finished.The tradition spark machine mainly is the spacing that increases between electrode and workpiece in axially movable electric spark mode constantly, utilizes cold oil that the process residues that electric spark produces is removed, and avoids workpiece and inter-electrode short-circuit not to produce spark discharge.And diamond grinding head is the high temperature sintering slug press, and its shape and position degree low precision use electrode and workpiece not to make the processing mode that the position degree evenly changes on circumference, are difficult to revise former blank error, even error is strengthened.Making workpiece and electrode do uniform relative motion on circumference, to eliminating form error and the position error of bistrique blank on circumference, not only still is all to be rationally feasible in the practical application theoretically.Thereby guaranteed the specification requirement of diamond grinding head series products axiality and endoporus circularity.Because processing, becomes according to mechanical precision and guarantees by artificial control the center, not only precision is high but also stable.This processing method is also saved the consumption of copper electrode.
Although it is pointed out that here a kind of spark machine workbench of the utility model is described in detail, with regard to this area staff, the similar modification of the class Sihe of making on this basis all should belong to the utility model protection domain.
