Abstract
The invention provides a device for measuring thicknesses of air inlet and outlet sides of a turbine blade. The device can solve the problem that the existing measurement device and method is low in measurement precision, low in efficiency and high in cost. The device is characterized by comprising a standard block and a point micrometer, wherein the standard block is in a shape like a Chinese character 'ao' (concave), concentric positioning holes are symmetrically arranged on two lateral arms of the standard block, and measurement rods at two ends of the point micrometer respectively penetrate through the corresponding positioning holes.
Description
Technical field
The present invention relates to the field of measuring technique of blade, especially relate to blade into and out of vapour side thickness measure field, be specially turbine blade inlet, outlet side measurer for thickness.
Background technology
Development along with Turbine Blade Design, manufacturing technology, blade manufacturing accuracy and manufacturing require to improve constantly, require also more and more stricter to the thickness measure of inlet, outlet side, usually in design, give the thickness measure requirement of position, spacing inlet, outlet limit, see illustrated in figures 1 and 2ly, d is the thickness signal of position to be measured among Fig. 2.Usually adopt manual line to add miking, the methods such as profile model line light leak measurement and three-dimensional coordinates measurement are measured, above method has weak point: at first, manual line adds miking, it is difficult to control the accuracy of line, cause the measuring position deviation, can only use in the very low occasion of positional precision; Secondly, profile model line light leak is measured, each gear of each blade all needs to make special sample, and light leak mensuration error is larger, can't use in the high occasion of accuracy requirement, can't directly obtain data, must carry out large numerical quantity conversion calculations, simultaneously, use the method must cooperate clamping device to fix blade, its measurement is loaded down with trivial details, and it is high to measure the frock cost; In addition, although adopt the three-dimensional coordinates measurement measuring accuracy higher, its Measuring Time is long, efficient is low, and three coordinate measuring machine in-house facility cost is high, and its technical requirement to survey crew is also relatively high, also is not suitable for the mass detection of production scene.
Summary of the invention
For the problems referred to above, the invention provides turbine blade inlet, outlet side measurer for thickness, it can solve the problem that measuring accuracy is low, efficient is low, cost is high of existing measurement mechanism and method existence.
Turbine blade inlet, outlet side measurer for thickness, it is characterized in that: it comprises calibrated bolck and point micrometer, described calibrated bolck is " recessed " font, symmetrically on its two side arms has a concentric pilot hole, and the two ends measuring staff of described point micrometer is worn respectively correspondence and passed described pilot hole.
It is further characterized in that:
Described pilot hole center to the distance of described calibrated bolck inwall is that the position that need to measure of blade inlet, outlet side thickness is to the distance of blade trailing edge.
The beneficial effect of measurement mechanism of the present invention is: during detection calibrated bolck inwall and blade inlet, outlet edge joint are touched, because the pilot hole center is the distance that needs the measuring position to arrive the blade trailing edge on the calibrated bolck to the distance between the calibrated bolck inwall, namely over against the position that blade need to be measured, point micrometer two ends measuring staff is contacted the reading that reads on the point micrometer with blade part to be measured get final product after point micrometer two measuring staffs pass from pilot hole; It is simple in structure, convenient processing and manufacture, measurement simple operation, measurement result are accurate, thereby can greatly improve and measure efficient and reduce the frock cost, is applicable to the mass detection of production scene; And, by manufacture and design, the on-the-spot different pilot holes center of changing is to the calibrated bolck of calibrated bolck inwall heart size, or the on-the-spot point micrometer of changing different ranges goes for the measurement of any blade inlet, outlet thickness.

Fig. 2 is the local enlarged diagram of A section among Fig. 1;
Fig. 3 is measurement mechanism structural representation of the present invention.
Embodiment
See Fig. 3, it comprises calibrated bolck 1 and point micrometer 2 apparatus of the present invention, and calibrated bolck 1 is " recessed " font, and symmetry has concentric pilot hole 3,4 on its two side arms, and the two ends measuring staff 5,6 of point micrometer respectively correspondence passes pilot hole 3,4.Pilot hole 3,4 centers to the distance L of calibrated bolck inwall 7 is that the position that need to measure of blade inlet, outlet side thickness is to the distance of blade trailing edge
