Description
Technical Field
The utility model relates to a location frock for processing bolt straight line groove especially relates to a location frock that is used for processing bolt straight line groove on wire cut electrical discharge machining in batches.
Background
A Wire electric Discharge Machining (WEDM for short) belongs to the field of electric Machining, and is characterized in that when a phenomenon and reasons of corrosion and damage of a switch contact caused by spark Discharge are researched by a former Soviet union, the instantaneous high temperature of electric sparks can melt and oxidize local metal to be corroded, so that an electric Discharge Machining method is created and invented. The wire cutting machine was invented in the former soviet union in 1960, and China is the first country for industrial production. Free positive ions and electrons accumulate in the field, quickly forming an ionized conductive channel. At this stage, a current is established between the plates. Resulting in numerous collisions between the particles, forming a plasma and rapidly rising to a high temperature of 8000 to 12000 c, momentarily melting some of the material on the surfaces of the two conductors, while a bubble is formed due to the evaporation of the electrodes and the dielectric liquid and its pressure rises regularly up to very high levels. The current is then interrupted and the temperature suddenly drops, causing the bubbles to implode, creating a motive force that throws the dissolved material out of the crater, and the corroded material recondenses into small spheres in the dielectric fluid and is drained away by the dielectric fluid. Then, the discharge phenomenon is uniform and consistent through monitoring and control of NC control and execution of a servo mechanism. The pulse power supply emits a series of pulse voltages to the workpiece electrode and the molybdenum wire electrode. And working liquid with insulating property is sprayed between the molybdenum wire and the workpiece. When the distance between the molybdenum wire and the workpiece is small to a certain degree, the working liquid is broken down under the action of pulse voltage, an instant discharge channel is formed between the molybdenum wire and the workpiece, and instant high temperature is generated, so that metal is locally melted and even vaporized to be corroded. The workbench drives the workpiece to continuously feed, and the required shape can be cut.
In the production when mechanical die part carries out line cutting, often need process some tiny narrow slits (generally 0.2mm-1mm), like the straight line groove of nut and bolt, need fix the cutting part, avoid it to take place the displacement when the cutting, lead to the cutting failure, however current positioner mostly uses flat tongs centre gripping, and a part can only be clamped in one-time processing, and the operation degree of difficulty is big, can't fix the part fast in batches, has reduced the work efficiency of cutting.
