Once-forming direct making method of assembly-free mechanical mechanism and application thereof

Abstract

The invention provides a once-forming direct making method of an assembly-free mechanical mechanism, comprising the following steps of: establishing a three-dimensional model of each part in the mechanical mechanism, and digitally assembling each part model to obtain the three-dimensional model of the mechanical mechanism; inducing the three-dimensional model of the mechanical mechanism into a laser rapid forming device, and directly making the whole mechanical mechanism through once forming by adopting laser rapid forming; and postprocessing the formed mechanical mechanism to obtain a finished mechanical mechanism. The invention also provides application of the method. The invention breaks through traditional design and making ideas of independently processing each part and then assembling the mechanical mechanism, establishes digitalized design and assembly, and establishes a novel idea of directly making the whole mechanical mechanism through once forming, thereby not only saving the subsequent assembly process, but also not limiting the design process of the mechanical mechanism by the traditional processing method and the traditional assembly means and ensuring that the structure and the connecting mode of the mechanical mechanism are flexible and various.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a digital assembly-based direct manufacturing method of an assembly-free mechanical mechanism that changes traditional design and manufacturing concepts and its application. Background technique [0002] Mechanical mechanisms are widely used in industrial and civil fields, such as: shaft mechanisms, latch mechanisms, various motion conversion mechanisms, etc. In the traditional processing method, the parts that make up the mechanical mechanism are generally manufactured separately first, and then the parts are connected by rivets, pins, bolts and other fasteners to finally form a complete mechanical mechanism. This processing method has the following disadvantages: (1) each part needs to be processed separately first, and then assembled into a complete and usable mechanical mechanism, which has defects such as cumbersome procedures; (2) when designing...

AI Technical Summary

Problems solved by technology

This processing method has the following disadvantages: (1) each part needs to be processed separately first, and then assembled into a complete and usable mechanical mechanism, which has defects such as cumbersome procedures; (2) when designing the mechanical mechanism, the designer must consider the available mechanical mechanism Due to the operating space of the assembly and the required assembly method, this greatly limits its design ideas and limits the structure and connection methods of the mechanical mechanism.

In the existing technology, laser rapid prototyping technology is generally only used for the production and manufacture of a single part, but it has not been applied to the mechanical mechanism assembled from multiple parts, which makes the manufacturing of the mechanical mechanism greatly restricted and inconvenient
