Description
Technical field
The present invention relates to the materials processing technology field, more particularly, relate to a kind of high-pressure water jet cutting and positioning device.
Background technology
High pressure water jet is the new technology that nearly twenty or thirty grew up over year, this technology is with ordinary tap water pressurization and force water under high pressure to go out through a very little high-pressure water jet nozzle ejection of diameter by high-pressure pump, form one high-speed water jet, its speed can be up to 1000 meter per seconds, and this jet can be used to process various than soft material or thin hard material.Generally, add abrasive material in this jet, make it form one high speed abradant jet, this abradant jet just can be used to process the material of any quality.
In the high-pressure abradant jet current cutting process, run into following two problems through regular meeting:
1, as shown in Figure 1, the periphery of material is by other processing method completion of processing or just definite fully when the blanking, now need to adopt high-pressure water jet in material, to carry out other secondary operations, require the periphery of secondary operations and material to keep accurate position relation, promptly require accurate X value and Y value.
2, equally as shown in Figure 1, in the abradant jet process, required distance is accurate between the nozzle of abradant jet and the upper surface of material to be processed, promptly requires accurate Z value.Because abradant jet can be subjected to the influence of surrounding medium after the nozzle ejection, jet is forced to scatter.If this distance is excessive, on the one hand, effective thickness of cutting of material to be processed diminishes, and causes energy waste, and on the other hand, the jet that scatters can cause the original spout radius compensation of setting to produce error, influences the cutting position precision; If but this distance is too small, when just beginning to cut,, can produce a back pressure around jet expansion to the medium of nozzle upstream because jet can not effectively be discharged, cause the nozzle upstream medium to enter the abrasive material flexible pipe, cause cutting process to lose efficacy.
For guaranteeing that material secondary adds man-hour, satisfy the position accuracy demand of the periphery of material to be processed, the most frequently used method has two kinds.
First kind is that a high-resolution video camera is installed on nozzle, adopts this video camera to make a video recording, and determines the position relation through image processing process, and finally finish secondary operations.This method precision height can satisfy the demanding processing of some relative positional accuracies, but complicated operation needs plenty of time installation video camera and carries out the image processing.
Second kind is that nozzle is moved to material periphery sides to be cut top, with the naked eye estimates neutrality, thereby determines relative position.But,, adopt this kind method to be difficult to accurately with nozzle center and material periphery sides centering because nozzle face is a plane.Therefore, though this method is simple to operate, position error is bigger, is difficult to satisfy the Working position precision prescribed.
For the distance that guarantees nozzle and material upper surface to be processed satisfies required precision, the most frequently used method is slowly to move down nozzle to arrive definite position until nozzle.But since nozzle material more firmly, more crisp, when nozzle and material upper surface to be processed bumped, nozzle was more fragile, material to be processed also is scratched or breakage easily.For avoiding above-mentioned phenomenon, in the nozzle folding process, the operator need repeatedly move down nozzle one small distance, and takes multiple measurements, and could finally find the tram.Like this, cause the plenty of time waste, particularly at large-scale workbench, the operator needs multi-pass operation, causes great inconvenience.
In a word, no matter be determine nozzle center and material to be processed periphery apart from the time, still definite nozzle and material upper surface to be processed apart from the time, existing operating process is not simple to operate, and precision is not enough, is exactly that precision satisfies, complicated operation does not also have a kind of simple accurate method.
