Abstract

The invention provides a supporting and positioning device used for leaf petiole length measurement and a measurement method thereof, and can solve the problems that the leaf is not stable and the measurement result is inaccurate in leaf petiole length measurement through the existing method. The supporting and positioning device comprises a base plate, a support and a positioning plate. The support is fixedly installed on the base plate. The positioning plate is detachably installed on the support. The support is hollow cylindrical. The positioning plate is an annular positioning plate. The side wall of the support is provided with detection windows. When measurement is performed, the leaf is vertically placed on the supporting and positioning device used for measurement so that the axial positioning surface of the leaf and the upper surface of the annular positioning plate are enabled to be contacted and positioned. Zero setting is performed on the upper surface of the annular positioning plate by using a height gauge with a lever type screw gauge, and then the measurement head of the height gauge stretches into the support of the supporting and positioning device via the detection windows of the supporting and positioning device to be contacted with the surface to be measured of the leaf petiole so that various sizes of the length direction of the leaf petiole can be measured, the measurement method is simple and rapid and measurement efficiency is high.

Description

A kind of supporting and positioning device for blade grip linear measure longimetry and measuring method
Technical field
The present invention relates to Blade measuring technical field, be specially a kind of supporting and positioning device for blade grip linear measure longimetry and measuring method.
Background technology
Along with the development of blade design investigative technique, require more and more higher to the manufacturing accuracy of blade, more conventional traditional Blade measuring method can not meet now vaned accuracy requirement far away.For blade grip measurement of length, conventional traditional measuring method is: on measuring table, with two isometry blocks, blade is erect, blade grip length is measured again with height gauge, be not very large because blade contacts locating surface with two isometry blocks, in addition the center of gravity of blade own is not or not the center of measuring table, thus the blade unstable possibility that also there is inclination when causing measuring, result also in measurement result inaccurate; And the Method compare of this employing two isometry block is loaded down with trivial details, therefore makes troubles to measure batch.
Summary of the invention
For the problems referred to above, the invention provides a kind of supporting and positioning device for blade grip linear measure longimetry, it can solve blade instability, the inaccurate problem of measurement result that the two isometry block of existing employing comes to exist when blade grip linear measure longimetry is carried out in auxiliary blade setting; Present invention also offers blade grip measurement of length method for this reason.
A kind of supporting and positioning device for blade grip linear measure longimetry, it is characterized in that: it comprises base plate, bearing and location-plate, described bearing is installed on described base plate, described location-plate is removably installed on described bearing, described bearing is the tubular of hollow, described location-plate is circular orientation plate, and the sidewall of described bearing offers detection window.
Further, described detection window is vertical bar shape detection window.
Further, detection window on described bearing sidewall comprises two upper detection windows and two bottom detection windows, described two upper detection windows are just to setting, described two bottom detection windows are just to setting, and described upper detection window, bottom detection window are arranged along the side face uniform intervals of described bearing.
A kind of blade grip measurement of length method, it is characterized in that: supporting and positioning device and height gauge are positioned on measuring table, described supporting and positioning device comprises base plate, bearing and location-plate, described bearing is installed on described base plate, described location-plate is removably installed on described bearing, described bearing is the tubular of hollow, described location-plate is circular orientation plate, the sidewall of described bearing offers vertical bar shape detection window, be that upright state is positioned on described measurement supporting and positioning device by blade during measurement, the shank of blade is made to stretch in bearing through the endoporus of the circular orientation plate of described measurement supporting and positioning device from top to bottom, and the axial locating surface of blade is contacted with the upper surface of described circular orientation plate locate, with the described height gauge with lever silk table at the upper surface of described circular orientation plate to zero, then contact with the shank tested surface of blade in the bearing that the measuring head of described height gauge stretches into described supporting and positioning device by the detection window of described supporting and positioning device, thus record each size of blade grip length direction.
Supporting and positioning device of the present invention is used for blade grip measurement of length, it carries out contact location by circular orientation plate to the axial locating surface of blade, thus the shank of blade stretches in tubular bearing by the endoporus of circular orientation plate, whole supporting and positioning device is made to carry out reliable vertical supporting and location to blade, and to blade grip, height gauge directly treats that side is detected by the detection window that tubular bearing sidewall is offered, therefore it reliably can carry out vertical supporting and location to blade, when ensureing to measure, blade is stable, thus guarantee the accuracy of measurement result.And adopting bracing or strutting arrangement of the present invention to measure blade grip length, it measures simple, quick, measures efficiency high.
