Intelligent additive manufacturing device and method of large steel truss

Abstract

The invention discloses an intelligent additive manufacturing device and method of a large steel truss in the technical field of steel truss manufacturing. The device comprises a walking mechanism. Arotating seat is fixedly mounted on a top supporting frame of the walking mechanism. The top of the rotating seat is connected with a mounting seat. The side wall of the mounting seat is connected with a bearing arm. The right end of the bearing arm is hinged to a cantilever through a pin shaft. The cantilever is connected with a laser locating device. A telescopic air cylinder is further mountedat the top of the bearing arm. The output end of the right side of the telescopic air cylinder is movably connected with a supporting plate on the cantilever. According to the intelligent additive manufacturing device and method, laser locating and printing within any space range can be achieved, the flexibility of the locating manner is high, the printing material type and the supporting platformsize are not limited, and the locating and printing requirements of large objects can be met.

Description

technical field [0001] The invention discloses a large-scale steel truss intelligent additive manufacturing device and method, in particular to the technical field of steel truss manufacturing. Background technique [0002] There are many problems in the traditional large-scale steel truss production method, such as manual lofting cannot obtain the real size, can not effectively control the angle and size of each node in the space, it is difficult to measure and control the space storage of the steel truss during actual splicing, and the welding method is outdated. The production efficiency is low, and the welding quality is difficult to guarantee. [0003] In recent years, the use of additive manufacturing technology to print steel trusses has shown more and more advantages. The use of robotic cantilever positioning, CNC machine tool support platforms, computer remote control processing and other technologies to achieve three-dimensional printing of large objects makes mate...

AI Technical Summary

Problems solved by technology

However, the traditional large-scale additive manufacturing system mainly has major problems such as low positioning flexibility of laser light source, limited printing material type and support platform size, etc.

Since the laser light source is positioned by a large robot cantilever, it can meet the printing requirements to a certain extent, but it is not flexible enough for large objects, which may cause uneven laser irradiation intensity and greatly reduce the printing effect.
