Embodiment Construction

[0013] specific implementation plan

[0014] according to figure 1 , The comprehensive experimental device for cutting jet support is mainly composed of cavitation jet generating device, cutting force measuring device and vibration measuring device. The cavitation jet generating device includes a water tank 16, a motor 8, a high pressure pump 7, a pressure holding control cylinder 5, a cavitation generator 6, a pulse generator 4 and a nozzle 3, etc. The medium water is filtered from the water tank 16, pressurized by the high-pressure pump 7, and sprayed out from the nozzle 3 after the action of the cavitation generator 6 and the pulse generator 4. The impact force generated by the jet acts on the surface of the predetermined workpiece to provide Auxiliary support. The cutting force measuring device includes a dynamometer 9, an amplifier 13, a computer 11, and the like. The workpiece 15 is fixed on the workbench of the dynamometer 9 by screws, the base of the dynamometer 9 i...

Abstract

A comprehensive experimental device for cutting jet supporting comprises a cavitation jet generation device, a cutting force measuring device, a vibration measurement device and the like, wherein the cavitation jet generation device comprises a water tank, a control motor, a high-pressure pump, a pressure-maintaining control cylinder, a cavitation generator, a pulse generator, a spray nozzle and the like; the cutting force measuring device mainly comprises a dynamometer, an amplifier, a computer and the like; and the vibration measurement device comprises a vibration measuring head, a conditioning instrument, a computer and the like. The comprehensive experimental device is adopted to achieve a comparison experiment so as to check both the possibility and application effect of taking cavitation pulse jet as the support of a follow-up process system, and then whether deformation and vibration of thin-walled low-rigidity parts in the processing process can be reduced and eliminated or not can be judged.

Description

technical field [0001] The invention relates to the design of a comprehensive experimental device, in particular to a comprehensive experimental device for cutting jet support. The possibility and practical application effect of using cavitation pulse jet as the support of the follow-up process system are tested through comparative experiments. Background technique [0002] High-pressure water jet technology is a new technology developed rapidly in recent decades, and has been widely used in mining, metallurgy, petroleum, construction, chemical industry, municipal construction and medicine. The cavitation phenomenon is the phenomenon of the generation, growth and collapse of cavitation bubbles when the local pressure is lower than the saturated vapor pressure in the process of fluid flow. . The introduction of cavitation into the field of high-pressure water jet technology is cavitation water jet technology. The high impact force caused by cavitation collapse can enhance th...
