Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to an adsorption processing device for large and complex structural parts. Background technique [0002] Large and complex parts mainly include two categories: complex structure and complex surface, which usually have common characteristics such as large size, complex shape, high requirements for position accuracy and surface quality, and thin-walled structure. Typical large complex parts include large aviation thin-walled parts, large space station cabin structure parts, heavy gas turbine components, large fan blades, ship propellers, etc., which are crucial to national security, and their efficient and high-quality manufacturing is an urgent problem to be solved. Large and complex structural parts pose a severe challenge to the processing capacity of the basic device. On the one hand, due to the large size and mass of the workpiece, there are problems such as dif...

Large and complex structural parts pose a severe challenge to the processing capacity of the basic device for processing and manufacturing

On the one hand, due to the large size and mass of the workpiece, there are problems such as disassembly, transportation, and re-debugging, and the size of such parts often exceeds the processing capacity of ordinary machining centers (especially the working space). Large-scale special-purpose processing devices for some parts, the cost is extremely high and the utilization rate is low, resulting in waste of resources and a sharp increase in production costs

In addition, there are also problems such as inconvenient disassembly and difficult transportation to the processing site for the later maintenance of such large-scale equipment.

[0003] In the prior art, the main method of processing large and complex parts is to use the gantry type multi-axis CNC machine tool for processing. Due to the large size of the workpiece, the required processing machine tool is also large in size and expensive

Moreover, there are several shortcomings: the processing mode is fixed, usually does not have flexibility and parallel processing capabilities; the processing object is relatively single, does not have reconfigurability, and is not suitable for complex and diverse processing environments; processing efficiency is low

The five-degree-of-freedom parallel mechanism is a very important type of parallel mechanism, but there are very few successful application cases of the five-degree-of-freedom parallel mechanism

[0005] However, there are still some key technical problems to be solved in the existing technology, such as the kinematics and structural complexity and rigidity brought by the five-branched chain, especially when processing large and complex structural parts, the processing device is bulky and cannot be miniaturized and convenient. chemical processing etc.
