Description
The present invention relates to a clamping device for an electrode for electric discharge machining, and more particularly to a clamping device for an electrode for electric discharge machining, more specifically, a fixing bolt having a hemispherical head is fastened to a lower portion of a holder on which an electrode is installed, And the rotating ring is provided with a means for engaging the head with the head within one rotation when the head is fitted so that the holder is mounted on the fastening means, whereby the electrode can be quickly fastened to the machine tool by a small rotation .
Generally, electric discharge machining is a special processing method for precisely machining hard materials such as cemented carbide, high speed steel and heat resistant steel. In the electric discharge machining, a workpiece is processed in a pattern shape of an electrode by a discharge phenomenon generated when an electrode having a forming pattern formed on one surface is brought into contact with a workpiece contained in an electrolytic solution. At this time, a clamping device or holder for selectively fixing the electrode to the electric discharge machining apparatus is required.
Conventional Utility Model Registration Nos. 434123 and 434124 disclose a clamping device for an electrode for electric discharge machining. This is configured such that a screw hole fixed to an electrode holder of a machining bed or an electric discharge machine of a CNC machine tool or the like and a holder provided with an electrode are provided, And a female screw portion to which the screw shaft is fastened.
However, when the holder is coupled or disassembled from the coupling port for replacing the electrode or the like, the operating knob is rotated several times. In the large-scale processing line in which a plurality of electrodes are provided, Needed a lot of time and manpower.
In view of this, in the prior arts 1116220 and 2008-0003628, a bevel gear is provided on a screw shaft of a coupling and one of the bevel gears is provided with a tool coupling groove into which an electric screwdriver is fastened, So that the clamping device can be quickly fastened and separated.
However, since a pair of orthogonal bevel gears must be mounted inside the coupling hole, the configuration is complicated and the screw shaft is rotated several times before the holder is mounted on the coupling hole.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide an apparatus and a method for assembling an electrode, a fixing bolt having a hemispherical head on a lower portion of the holder, The rotation ring is provided with a means for engaging the head with the head within one rotation when the head is fitted, so that the holder can be fastened to the fastening means. .
To this end, the present invention comprises a holder in which an electrode is installed and a fixing means for fixing the holder to the machine tool; A fixing bolt having a hemispherical head is fastened to a center of a bottom surface of the holder; Wherein the fixing means comprises a body on which the holder is placed, a cylindrical space portion is provided in the body, and a cylindrical rotating ring is fitted in the space portion and rotated in place; Wherein the rotary ring is provided with an opening portion in which the head portion is inserted through the head hole of the upper portion of the body and a projection portion formed on the hemispherical outer peripheral surface of the head portion is formed downward, And the head portion is hooked on the protruding portion by changing the position of the protruding portion.
According to the present invention, a rotary ring is provided inside the fixing means fastened to the machine tool. The rotary ring has a structure in which a head portion of a fixing bolt fastened to a lower portion of the holder is inserted between a pair of rotary plates which are separated from each other, and protrusions, which are caught in the head portion, are formed on opposite sides of the rotary plate, And a hemispherical head portion is sandwiched between the protrusions. The rotary ring is rotated by the rotation of less than one revolution to pull the head while the projection is rotated. In this process, the holder is fastened to the fixing means.
In an embodiment of the present invention, an electrode is fixed to the holder. When the rotary ring of the fixing means installed on the machine tool is rotated within one rotation, the holder is mounted to the fixing means. Since the holder can be quickly separated from the fixing means, the operation of fastening the plurality of electrodes to the fixing means can be simplified.
