Abstract

The invention discloses a single-measuring-head scanning and repair device for damaged parts. The device comprises a three-dimensional optical scanning system and a laser cladding repair system; the three-dimensional optical scanning system comprises an acquiring unit and a data generation unit; the acquiring unit is used for acquiring grating stripe images on the surfaces of the damaged parts; the data generation unit is used for generating three-dimensional point cloud data on the surfaces of the damaged parts and generating defect digital models of defect areas of the damaged parts by using the three-dimensional point cloud data; and the laser cladding repair system repairs the damaged parts according to the defect digital models. The invention further discloses a single-measuring-head scanning and repair method for the damaged parts; and the method uses the three-dimensional optical scanning system and the laser cladding repair system for scanning and repairing the damaged parts. Three-dimensional optical scanning and laser cladding repair are combined for repairing the damaged parts; and the single-measuring-head scanning and repair device and method for the damaged parts have such advantages as low equipment cost, high scanning precision, high integration degree, short repair time and wide application range.

Description

technical field [0001] The disclosure belongs to the technical field of three-dimensional optical non-contact measurement and metal additive manufacturing, and in particular relates to a single measuring head scanning and repairing device and method for damaged parts. Background technique [0002] The traditional manual repair method is difficult to adapt to high temperature, narrow space, continuous operation, complex damage and other working conditions. The repair quality and repair time are greatly affected by human factors. The existing digital models of defects used in laser cladding repair are mostly obtained by manual modeling, which has the disadvantages of poor robustness, low repair accuracy, and large influence by human factors. Existing 3D optical scanning systems are seldom combined with laser cladding repair systems for remanufacturing repair of damaged parts. Multiple probes will increase the difficulty of realizing multiple groups of black and white camera c...
