Example Embodiment

[0043] Example 1

[0044] This embodiment provides a device for taking images of the inner and outer walls of a round hole workpiece. The schematic diagram of the device is as figure 1 Shown, including: inner wall camera 1, inner wall telecentric lens 2, inner wall light source 3, round hole workpiece 4, plane mirror 5, mirror sleeve 6, manual horizontal rotating table 7, manual XY sliding table 8, outer wall camera 9 , The outer wall telecentric lens 10, the outer wall light source 11, the workpiece fixture 12, the rotary motion platform 13, the linear motion platform 14, the motor support 15, the vision system support 16, the outer wall camera support 17, the inner wall camera support 18 and the processor 19.

[0045] In practical applications, the inner wall CCD camera 1 and the outer wall CCD camera 9 may be CCD (Charge-coupled Device) cameras or digital cameras. The above-mentioned flat mirror 5 may be a flat mirror with an inclination, such as a 45-degree flat mirror. The af...

Example Embodiment

[0073] Example 2

[0074] based on figure 1 As shown in the device for taking images of the inner and outer walls of a round hole workpiece, the processing flow of a method for taking images of the inner and outer walls of a round hole workpiece provided in this embodiment is as follows figure 2 As shown, including the following processing steps:

[0075] Step S210: Mount the round-hole workpiece on the rotary motion platform through the workpiece fixture, so that the axis of the workpiece is consistent with the axis of the rotary motion platform.

[0076] Step S220: Adjust the manual XY sliding table to make the axis of the 45-degree plane mirror consistent with the axis of the rotating platform; adjust the manual horizontal rotating table to make the direction of the reflecting surface of the 45-degree plane mirror and the direction of the outer wall CCD camera Consistent, that is, parallel to the axis of the round hole workpiece.

[0077] Step S230: Adjust the inner wall CCD came...

Abstract

The invention provides a method and a device for shooting images of the inner and outer walls of a circular-hole workpiece. The device mainly comprises a plane reflector, a linear motion platform, a rotary motion platform and an inner wall camera, wherein the plane reflector stretches into the circular-hole workpiece from the bottom of the circular-hole workpiece under the support of a sliding platform and reflects images of the inner wall of the circular-hole workpiece; the inner wall camera is mounted above the circular-hole workpiece, and an image forming surface of the inner wall camera is perpendicular to a reflection surface of the plane reflector; the circular-hole workpiece is driven to move to a starting height by the linear motion platform, is driven to rotate to a starting angle by the rotary motion platform and then is photographed so as to obtain the images of the inner wall of the circular-hole workpiece. By virtue of the device, the inner wall camera is capable of conveniently shooting the images of the parts at different heights of the inner wall of the circular-hole workpiece under the cooperation of the plane reflector, and the images of the inner wall are further stored and combined by a processor so as to obtain an integrated image of the inner wall of the circular-hole workpiece.

Description

technical field [0001] The invention relates to the technical field of workpiece surface detection, in particular to a method and device for taking images of the inner and outer walls of a circular hole workpiece. Background technique [0002] At present, functional parts with small shapes and sizes are being developed and applied more and more widely in the fields of automobile manufacturing, aerospace and other fields, and the surface quality of these microstructured parts is also put forward higher and higher requirements. Among them, there are more and more requirements for the quality inspection of the outer wall surface and the inner wall surface of the round hole workpiece, especially for some round hole workpieces with thinner tube walls, it is necessary to detect the quality of the inner wall and outer wall surface of the workpiece at the same time, so that Find problems such as penetration defects. [0003] It has always been a difficult point to detect the inner ...
