Abstract

The invention relates to the field of advanced manufacturing and intelligent equipment, in particular to an SLM manufacturing basic part positioning image acquisition device. The device comprises a frame rod, a guide bar supporting seat, a lead screw supporting seat, an industrial camera supporting plate, a box-type linear sliding block bearing guide rod, a high-precision motor, an annular LED lamp, an industrial camera, a light barrier, a controller and the like. The high-precision motor and a damping rubber pad are connected with a high-precision motor support through screws, a synchronous pulley on the high-precision motor is connected with a synchronous pulley of a lead screw through a synchronous belt, a first box-type linear sliding block bearing is installed on a second box-type linear sliding block bearing guide rod, the industrial camera is connected with a lamp holder, the industrial camera supporting plate and a camera fixing piece, and the lamp holder is connected with theindustrial camera supporting plate through a jackscrew. The device is portable, convenient to install and light in weight, and can be used for current universal SLM equipment; a one-way light-transmitting plate is adopted, external light interference is avoided, and the image is stable; and system light source and focal length are convenient to adjust, and collected images are clear.

Description

technical field [0001] The invention relates to contour image recognition and coordinate extraction of a basic part of a forming chamber of a selective laser melting (SLM) forming equipment, and in particular to a device and method for acquiring positioning images of basic parts in SLM composite manufacturing. Background technique [0002] Traditional machining has the advantages of fast processing speed and low cost, but it cannot process complex special structures and cannot meet customers' individual requirements for workpieces. Selective Laser Melting (SLM) is one of the most promising technologies in the field of additive manufacturing (also known as 3D printing). This technology uses a high-energy-density laser beam to rapidly melt and solidify metal powder to form parts with complete metallurgical bonding and a density close to 100%. This technology can form components with any complex structure, but compared with traditional machining, processing Long time and high ...

Problems solved by technology

This technology uses a high-energy-density laser beam to rapidly melt and solidify metal powder to form parts with complete metallurgical bonding and close to 100% density; this technology can form components with arbitrary complex structures, but compared with traditional machining, processing Long time and high processing cost

[0003] Some parts have both a simple structure and a complex structure; for example, the impeller has both a simple structure-a solid disc-shaped part and a complex structure-the blade part; if it is fully processed by traditional machining, the blade part is difficult to form and easy to deform , The processing cost is high; if SLM technology is fully used, the molding time and processing cost will be greatly increased; if the part is divided into two, the solid disc-shaped part is formed by traditional machining, and then the blade structure is formed by SLM on the solid disc-shaped part , which can realize high-efficiency and low-cost processing of parts
