Rotary endoscope fixture suitable for end of mechanical hand and inner hole image acquisition method

Abstract

The invention provides a rotary endoscope fixture suitable for an end of a mechanical hand and an inner hole image acquisition method. The rotary endoscope fixture includes a rotating device and an image acquisition device. The rotating device includes a mechanical switching flange (2), a flange supporting frame (3), a stepping motor (4), a rotating platform (5), a rotating shaft (6), a bearing seat (7), a driven synchronous pulley (8), a driving synchronous pulley (9), and a flange shaft bracket (11). The image acquisition device includes a camera fixing block (12), an industrial camera (13)and an endoscope (14). The rotary endoscope fixture is simple and compact in structure, safe and reliable, acquires complete inner wall image information of a small-diameter deep blind hole in a workpiece by using a translation function of the end of the mechanical hand and a rotation function provided by the fixture, can directly acquire the inner wall information of the small-diameter lightly deep blind hole of the workpiece on a streamline, is convenient and fast in detection, is less affected by surrounding environment, and improves the detection efficiency and the detection accuracy.

Description

technical field [0001] The invention relates to the technical field of image information collection and production automation of the inner wall of a workpiece, in particular to a rotating endoscope fixture suitable for the end of a manipulator and a method for collecting images of inner holes. Background technique [0002] In many auto parts, many small-diameter, deep-depth blind holes play a very important role, and defects such as shrinkage cavity, shrinkage porosity, and cracks on the inner wall of the hole due to processing will affect the performance of the part. Therefore, the actual production has high requirements on the surface quality of the inner wall of the hole. The existing method of detecting the quality of the inner wall of the hole is the manual visual inspection method, that is, a person holds a flexible endoscope to inspect the inside of the hole, and judges whether the inspection result is qualified by visual inspection. This requires the full participat...

Problems solved by technology

However, this method needs to install a reflector in the hole, and requires the small hole of the workpiece to be a through hole, and the depth of the hole should not be too large, which is not suitable for the scene when the workpiece is a deep blind hole.
