Abstract
The high precision spherical degree pneumatic measuring system features in the stabilizer air supply connecting with the adaptor that connected with the main nozzle, which connects with the back pressure air chamber, the inspection gauge and pressure transmitter, the signal adjustor, D/A and data collection card, the industrial control computer sequentially, with the inspection gauge in high roundness precision with 6 gauging heads. It stands out with the following features: 1. synchronically inspecting the sample dimension relative displacement using multi sensor and multi inspecting spots distributed method on the spherical gauge, 2, pneumatic needle sensor's inspection side located on the same spherical surface, with the central axis cross point of the nozzle with the center of circle of the spherical surface, 3, using the relative displacement of the automatic sampling sensor to calculate the radius and roundness of the spherical surface to be inspected.
Description
Technical field
The present invention relates to a kind of high-accuracy sphericity pneumatic measuring system.
Background technology
The pneumatic gauging method is as measuring media with gases at high pressure, utilize flow or the pressure characteristic that with the difference of the physical dimension of nozzle or shape change of gas in air chamber, size quantity or displacement are converted to the variable quantity of flow or pressure, and further be converted into electric parameter, thereby realize the measurement of size and displacement.Because pneumatic sensing mode can realize non-cpntact measurement, and high pressure draught has cleaning action when spraying to surface of the work, and is not high to environmental requirement; Advantage such as simple in structure in addition, convenient operating maintenance, cost are low and be widely used in fields such as machinery, metallurgy, space flight.Member with spherical surface plays an important role in mechanical system usually, and its major parameter such as diameter, sphericity etc. need to satisfy necessary machining precision.The sphere measurement method of parameters mainly contains three-dimensional coordinates measurement method, section gauge method etc., sphere interferometry etc. at present.From the research situation of both at home and abroad sphere being measured, adopt single gauge head multi-measuring point method to measure sphere diameter and sphericity, because measuring system requires to have the rotary main shaft of very high degree of precision, precision is difficult to improve.
Summary of the invention
The purpose of this invention is to provide a kind of high-accuracy sphericity pneumatic measuring system, adopt many gauge heads relative measurement method, accurately measure the sphericity and the radius of sphere or ball-and-socket workpiece.
The present invention is achieved like this, it comprises pneumatic part and electric and conversion part, it is characterized in that pneumatic part is by pressure-stabilized air source, divider, main burner, the back pressure air chamber, gauge is formed, electric and conversion is partly by pressure unit, signal condition, analog to digital conversion and data collecting card, industrial control computer, display, printer is formed, pressure-stabilized air source connects divider, divider connects main burner, main burner connects the back pressure air chamber, the back pressure air chamber connects gauge and pressure converter, the pressure converter connects signal condition, number conversion of signal condition connection mode and data collecting card, analog to digital conversion and data acquisition card connection industrial control computer, industrial control computer connects display and printer, and gauge is the spherical gauge of high precision, arranges 6 gauge heads on ball gauge.
Advantage of the present invention is: (1) uses the multisensor of sphere gauge, the distribution measuring mode of multi-measuring point, the size relative displacement on the synchro measure sampling spot; (2) the air needle type sensor measuring junction is positioned on the same sphere, and the axis intersection point of gaging nozzle is this sphere center of circle; (3) relative displacement that utilizes the automatic sampling sensor of computing machine to measure solves the coordinate of corresponding measurement point, and carries out the sphere match, asks radius, the sphericity of calculating tested sphere.
