Embodiment Construction

[0027] The present invention will be further described below in conjunction with drawings and embodiments.

[0028] Such as figure 1 As shown, the present invention includes a support module, a power module, a transmission module and a detection module. The power module and the transmission module are respectively installed on the upper and lower sides of the support module, and the detection module is fixedly connected to the transmission module. The support module is used to support the whole device, the power module provides the operating power of the mechanism, and the transmission module is responsible for rotating the detection module with light source and camera at a certain speed to detect shaft parts.

[0029] Such as figure 1 As shown, the support module includes a frame 1-1, a sliding bearing 1-2, a positioning block 1-3 (for placing shaft parts), a spring 1-4 (for matching the positioning block), and a positioning sleeve 1-5 (for cooperating with the positioning ...

Abstract

The invention discloses a device for collecting surface panorama images of shaft parts for defect identification. A movement mechanism is a gear and gear ring mechanism, a camera and a light source are fixedly connected to a gear ring in the proper scanning angle through connecting pieces, the device selects three evenly-distributed pinions to be matched with the gear ring, one of the three pinions is a driving gear fixedly connected with a shaft, and the other two pinions are arranged to be driven gears capable of rotating freely. During detecting, a conveying platform transports the shaft parts to the clamping position, after a light sensor receivers a signal, the shaft parts are pushed to compress springs so as to fix the shaft parts, then a servo motor moves, and through belt transmission and gear and gear ring transmission, the light source and the camera rotate around the axes of the shaft parts simultaneously to achieve the detection effect. According to the device, machining iseasy, the cost is low, the structure is simple, maintenance is convenient, the images of the shaft parts can be automatically collected, and the detection speed can be adjusted.

Description

technical field [0001] The invention belongs to the field of nondestructive testing, and in particular relates to an image acquisition device of an image acquisition device of a detection system. Background technique [0002] Non-destructive testing is an important part of the production process of modern manufacturing. It is widely used in product design, material selection, processing and manufacturing, finished product inspection, in-service inspection (maintenance), etc., even in non-manufacturing industries. The application of non-destructive testing is conducive to quality control, cost reduction, simplified operation, and can ensure the safe operation and effective use of products. [0003] The invention relates to a non-destructive testing device for shaft defects. Shafts are mechanical parts that support transmission parts and rotate with them to transmit motion or torque. Shaft parts are generally rotary parts, but there are also other cross-section types (such a...
