Workpiece position-changing machine, workpiece position-changing processing method and system

Abstract

The invention discloses a workpiece position-changing machine. The workpiece position-changing machine comprises a working platform, wherein the working platform can be pivoted and is used for bearing a workpiece to be machined; the workpiece comprises a plurality of surfaces which enclose a three-dimensional structure; the working platform comprises a first working surface and a second working surface which are distributed along the pivoting direction; and when the working platform is pivoted, the first working surface and the second working surface can support two adjacent surfaces in multiple surfaces of a workpiece. The invention also discloses a workpiece position-changing processing system and a workpiece position-changing processing method using the workpiece position-changing machine provided by the invention. Since the two working surfaces in the workpiece position-changing machine can support the two adjacent surfaces of the workpiece in the pivoting direction when the working platform pivots, the position-changing processing of the workpiece is finished under the condition that the auxiliary devices such as clamps and positioning devices can be not arranged or a few amount of auxiliary devices is arranged, so that the process can be simplified, high-efficiency production of the workpiece is realized. The invention is especially applicable to high-efficiency batch production of large workpieces in engineering machines.

Description

technical field [0001] The invention relates to the field of workpiece displacement processing, in particular to a workpiece positioner, a workpiece displacement processing system and a displacement processing method using the workpiece positioner. Background technique [0002] In the field of workpiece processing, especially the field of workpiece welding, a displacement processing method is commonly used. During the processing of the workpiece, the method displaces the workpiece to realize the processing of each surface of the workpiece. [0003] Among them, in the field of construction machinery, since construction machinery is responsible for all kinds of heavy construction of construction projects such as construction, chemical industry, coal mines, ships, bridges, and nuclear power, often its basic load-bearing parts such as turntables, underframes, beams, arms and other components are both Big and heavy. Therefore, the manufacture of these basic load-bearing members ...

AI Technical Summary

Problems solved by technology

Therefore, under the influence of auxiliary components such as fixtures and positioning devices, the workpiece cannot be welded on all the welds on each surface after displacement, and the rest of the unwelded welds still need to be turned over with the help of cranes and other lifting tools after the workpiece falls to the ground. Positioning; and also due to the existence of fixtures, positioning devices, etc., the use of this type of positioner also cannot realize the second and third assembly positioning welding of the workpiece during the turning and displacement. This part of the work still has to be done on the workpiece After landing, it is completed by turning over with the help of cranes and other spreaders; therefore, this type of positioner not only does not bring convenience, but also increases the process and increases the workload of repeated clamping of the workpiece on the positioner

This can be barely overcome during the single-piece production of the workpiece, but the above-mentioned method will seriously restrict the production during mass production.
