Embodiment Construction

[0023] This part is the embodiment of the present invention, which is used to explain and illustrate the technical solution of the present invention.

[0024] A waviness measuring device, comprising a spline 1, a sensor 2 and a data transmission and power supply module 3, a number of sensors 2 are distributed on the spline 1 at certain intervals, and the data transmission and power supply module 3 is connected to all sensors 2 for data transmission ;Sensor 2 is a distance sensor, and the detection direction is below spline 1.

[0025] Further, spline 1 is a strip-like structure.

[0026] Further, the spline 1 is a material with suitable elasticity and rigidity, such as a polyurethane rubber strip.

[0027] Further, the sensor 2 is a laser sensor or an infrared sensor.

[0028] Further, the probes of all sensors 2 are flush with the bottom of spline 1.

[0029] Further, the sensor 2 is connected to the spline 1 in a fixed installation manner, specifically, the sensor 2 is em...

Abstract

The invention belongs to the technical field of aircraft measurement, and discloses a waviness measuring device and a use method, the waviness measuring device comprises a spline, a plurality of sensors and a data transmission and power supply module, the plurality of sensors are distributed on the spline at certain intervals, and the data transmission and power supply module is in data transmission connection with all the sensors; the sensor is a distance sensor, and the detection direction is below the spline. According to the invention, waviness of surfaces with different curvatures can be rapidly measured; by customizing measuring devices of different sizes, the surface of any concerned aircraft part can be directly measured, and compared with a laser tracker and a laser scanning mode, the device is simple in structure, small in size and convenient to operate, and has better applicability to a measurement object, a measurement environment and a measurement site.

Description

technical field [0001] The invention belongs to the technical field of aircraft measurement, and relates to an aircraft surface measurement device, in particular to a waviness measurement device and a use method. Background technique [0002] Waviness, also known as waviness, is one of the shape error components that form the surface topography of workpieces or parts. It refers to those relatively wavy ups and downs that appear periodically and repeatedly on the surface of the workpiece due to the influence of pressure and deformation factors during the stretching or heat treatment of the parts during the processing process. Small shape errors. Waviness is an important part of surface quality control. [0003] At present, there are mainly two measurement methods, traditional tools and laser tracker measurement. [0004] If the surface waviness is measured using traditional measuring tools, it is necessary to place the spline or steel ruler at the measuring station first, ...
