For a turnery processing difficult problem for engineering ceramic material, propose the turning of application abrasive water jet traffic mirroring, both the flawless processing to the firmly crisp ceramic material of height can have been realized, to improve its combination property and service life, can, by the high pressure nozzle of mirror-image arrangement, make two beam streams support each other workpiece again, thus improve system rigidity, reduce workpiece elastic deformation, reduction and the vibration of suppression process system, with the problem such as avoid machining yielding.
Summary of the invention
The application abrasive water-jet that the object of the invention is to easily produce for the solution unmanageable problem of ceramic material and turnery processing the problem proposition of elastic deformation and vibration is processed ceramic material, mirror-image arrangement two high pressure nozzles, the scheme making two beam streams support each other workpiece, provides a kind of device to realize the retrofit of engineering ceramic material.
For achieving the above object, the technical solution used in the present invention is: this abrasive water jet traffic mirroring turning experiment device is primarily of compositions such as abrasive water-jet device, displacement measuring device and grip devices.
Above-mentioned abrasive water-jet device by water jet machining platform, extra high voltage system, add sand diced system, five axle Water Cutting systems, the automatic supply system of abrasive material, soft brush treatment system and oil cooling system etc. and jointly form.Two high-pressure grinding material water jet nozzle mirror-image arrangement is in the workpiece material left and right sides.
Above-mentioned grip device is made up of clamping element, clamp, rod member, contiguous block, gripper shoe and substrate etc., be connected with lathe big slide plate for spray gun, realize spray gun clamping, fix, and meet swaying of three direction rectilinear motions and a direction simultaneously, facilitate each to adjustment of spray gun, meet experiment parameter and regulate needs, ensure that processing is carried out smoothly.
Upper displacement measurement device is made up of infrared ray sensor, conditioner and computer etc., be used for gathering the displacement signal of workpiece, signal is through conditioner amplification filtering, be input to displacement acquisition card, Displacement Analysis software collection data are also analyzed, and can obtain misalignment break under corresponding machining condition.
The invention has the beneficial effects as follows, use this abrasive water jet traffic mirroring turning experiment device, namely can by the abrasive waterjet cutting of ceramic material, solve the unmanageable problem of ceramic material, improve combination property and the service life of ceramic part, again can by the high pressure nozzle of mirror-image arrangement, two beam streams are made to support each other, thus raising system rigidity, reduce workpiece elastic deformation, reduction and the vibration of suppression process system, with the problem such as avoid machining yielding.
