Problems solved by technology

[0003] Different electrodes should be designed according to different working conditions and work requirements. In the existing domestic EDM, the electrodes are directly clamped on the processing head, so it is necessary to design different processing heads for different working objects. The use of specific electrodes not only increases the design difficulty but also increases the development cost design difficulty, and brings inconvenience to on-site operation

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 , figure 2 As shown, the underwater electric discharge machining electrode multifunctional fixture provided by the present invention is installed on a moving part, and the multifunctional fixture moves with the movement of the moving part. The multi-function fixture is made of conductive materials such as aluminum or stainless steel. The clamp has three cutting electrode installation and positioning holes 2, 5, 8, and the clamping of each electrode is realized by the electrode positioning and holding fixture 25, 26, 27 arranged on the electrode position. The round holes allow for secure positioning of the electrode on the fixture. The electrode positioning and holding fixture is provided with cutting electrode clamping bolts 1, 3, 4, 6, 7, 9. For example, the electrode positioning and holding fixture 25 can be controlled by...

Abstract

The invention belongs to the technical field of the underwater electric discharging machining and particularly relates to a multi-functional clamp of an underwater electric discharging machining electrode. A plurality of mounting and locating holes of the cutting electrode are arranged on the clamp side by side, two sides of the mounting and locating holes of the cutting electrode are provided with clamping bolts; a water inlet joint and an EDM cable clamp fixing device are arranged on one side of the clamp of the invention, a plurality of water passes which are communicated together are arranged in the clamp, the water passes are communicated with the mounting and locating holes of the cutting electrode, and a plurality of water flow direction regulating devices are arranged on the waterpasses. In the multi-functional clamp of the invention, electrode clamping devices are separately arranged in different positions of the clamp of the electrode so as to meet the demand for processingdifferent workpieces and reduce the design cost and difficulty.

Description

technical field [0001] The invention belongs to the technical field of underwater electric spark machining, and in particular relates to a multifunctional clamp for underwater electric spark machining electrodes. Background technique [0002] With the increasing number of nuclear power plants in our country, after long-term operation of nuclear power plants, some components in high-radiation environments will be affected by factors such as high radiation, pressure, vibration, friction, and hydrogen adsorption, which will cause wear and aging of components. There will be situations where the reliability of some equipment is reduced or equipment components are damaged, and even failure or accident hazards are increasing. Therefore, every nuclear power plant must carry out regular maintenance. However, due to the special nature of nuclear power plants, some equipment cannot be operated by personnel at close range for a long time, especially the equipment in the refueling pool i...
