Flexible machining production line based on numerically-controlled machine tools

Abstract

A flexible machining production line based on numerically-controlled machine tools comprises the plurality of numerically-controlled machine tools, a tool three-dimensional library, a plurality of workpiece replacing platforms and two groups of transportation units, wherein the plurality of numerically-controlled machine tools and the plurality of workpiece replacing platforms are sequentially arrayed on the two sides of the tool three-dimensional library in sequence; the two groups of transportation units are arranged on the tool three-dimensional library respectively and are arranged between the plurality of numerically-controlled machine tools and the plurality of workpiece replacing platforms; worktables of the plurality of numerically-controlled machine tools are provided with at least two zero-point positioning devices; the tool three-dimensional library is provided with a plurality of supporting frame erecting positions; a tool supporting frame can be erected on each supporting frame erecting position; the bottoms of the tool supporting frames are provided with positioning lock heads with the quantity which is the same as the quantity of the zero-point positioning devices on the worktable of each numerically-controlled machine tool; each of the two groups of transportation units comprises a guide rail and a mechanical arm capable of sliding and moving on the guide rail; the guide rails in the two groups of transportation units are parallel to the long-strip-shaped tool three-dimensional library.

Description

technical field [0001] The invention relates to the field of industrial automatic mechanical processing and manufacturing, in particular to a flexible production line based on a numerical control machine tool and suitable for the production of multiple varieties and small batches of parts. Background technique [0002] With the increasing demand for individualized products, the production mode of parts has changed from mass production to medium and small batch production of various varieties. The gradual disappearance of the demographic dividend has led to rising labor costs for manufacturing companies. Therefore, how to improve the flexibility of the production line, improve the efficiency of machine tools and reduce the production line of operating workers is an urgent problem that traditional small and medium-sized enterprises need to solve. The current small and medium-sized enterprises already have basic CNC processing equipment, which can realize multi-variety and smal...

Problems solved by technology

[0004] The purpose of the present invention is to provide a flexible processing production line based on CNC machine tools. The technical problem to be solved is that traditional flexible production lines are mostly composed of specially configured online equipment, and the original CNC machine tools cannot be integrated and utilized. In turn, the cost of introducing flexible production lines is too high, which is not suitable for the normal operation of small and medium-sized enterprises
