System and method for rapid replacement and clamping based on zero point positioning

Abstract

The invention relates to a system and a method for rapid replacement and clamping based on zero point positioning, in particular to a process method for single and small-batch spaceflight component machining, and belongs to the technical fields of machining and automatic detection. According to the system and the method, the rapid replacement and clamping of workpieces is achieved by adopting a zero point positioning technology and an automation module. Through the adoption of the process layout and the automation module design, the system which is used for the rapid replacement and clamping of a machining center, is based on the zero point positioning technology, and has an off-line clamping alignment function is provided; and through the adoption of the basic principle of a zero point positioning module, the cooperative use with a transfer robot is achieved, the machine tool table top positioning is transformed, an automated gas circuit butt-joint device is arranged, an off-line rapid replacement and clamping alignment platform is added, an I/O expansion module is adopted for communication connection to a master control PLC, the signal integration and control operation is performed in a robot control system, and finally the rapid replacement and clamping of the machining center is achieved.

Description

technical field [0001] The present invention relates to a quick replacement system and method based on zero-point positioning, in particular to a processing method for a small batch of aerospace parts, which uses zero-point positioning technology and automation modules to realize quick replacement of workpieces, which belongs to mechanical processing And the field of automatic detection technology. Background technique [0002] Spacecraft structural products have the typical characteristics of "multiple varieties and small batches", and there are complex processing procedures and frequent workpiece replacements. In the current processing state, most of the replacement processes still rely on manpower, manual handling, and online processing. The clamping and alignment of workpieces leads to slow tooling replacement and long equipment downtime. After the processing is completed, parts are replaced by manpower, resulting in low production efficiency, which has become a bottlene...

Problems solved by technology

At present, quick-change loading and unloading equipment in the machinery industry is generally used in the initial stage of new production line construction. The main idea is to introduce a new type of machining center with the function of changing the platform, and all of them are mass-processed products, which do not involve human-computer interaction and do not have the old Equipment transformation technology does not meet the processing needs of small batches of multi-variety products
