Description
Technical Field
The invention belongs to the technical field of three-dimensional measurement, and particularly relates to full-surface three-dimensional measurement equipment and a measurement method for a complex columnar workpiece.
Background
With the rapid development of the automatic production technology of the advanced manufacturing industry and the continuous improvement of the product quality control system, people have higher and higher requirements on the precision, efficiency and automation degree of the detection of the geometric dimension, shape and position of a processed object, and especially the complexity of the shape of a part, the field performance and the real-time performance of measurement pose new challenges to the traditional precision measurement technology. In some specific occasions, such as real-time online detection of curved surface contours, micro-size and complex part features and the like, the problem faced by the traditional detection method is solved.
The measurement of physical dimensions using advanced tools such as imaging and laser is becoming more and more popular in advanced manufacturing. At present, the three-dimensional physical dimension measurement technology based on image technologies such as binocular vision and the like still does not obtain wide practical application due to the reasons of complex calibration technology, low precision and the like. The laser triangulation distance measuring technology is mature, the precision of the laser triangulation distance measuring technology can meet the requirements of modern precision manufacturing industry, and the repetition precision of the laser triangulation distance measuring technology can be better than 0.01mm generally.
A general measuring instrument or device can usually only obtain partial information of a workpiece to be measured, or can only measure a workpiece with a regular shape. However, in order to obtain an assembly space for the sake of product beauty, the surface shape of the workpiece is generally complicated and various, and the dimensional accuracy is required to be high. Cylindrical workpieces or products are common geometric forms, and the machining and manufacturing level of the workpieces or products can be accurately measured by acquiring all three-dimensional surface information of the cylindrical workpieces with complex surface characteristics for physical dimension measurement.
Heretofore, no apparatus or instrument has been available which is capable of making highly accurate measurements of the full three-dimensional surface of a cylindrical workpiece. The special measuring equipment for measuring the columnar workpiece by utilizing the image technology can only obtain partial projection information and cannot meet the problem that the measuring reference of the complex columnar workpiece is not in the axial direction. A single linear laser displacement sensor can only acquire partial surface information, and acquiring full surface information by using a workpiece rotating mode can generate the defects of high jig precision requirement, low measuring efficiency, sensitive measuring result to the position of a workpiece and the like.
