Automatic tool changing device

Abstract

The invention relates to the technical field of automatic machine tools, in particular to an automatic tool changing device. An upper guide rail body and a lower guide rail body are fixedly arranged on an upright and are of an upper-lower connection structure, chain knots, toolholder bodies and chain links are sequentially connected and placed in the upper guide rail body and the lower guide rail body, the chain links are fixed on the upper guide rail body and the lower guide rail body, the chain knots and the toolholder bodies are mounted and fixed on the chain links, a chain wheel mounting shaft is arranged on the upper guide rail body and the lower guide rail body, a chain wheel is connected on the chain wheel mounting shaft, a servo motor and a speed reducing mechanism are fixedly connected on the upper guide rail body and the lower guide rail body, the speed reducing mechanism is connected with the chain wheel to drive the same, and a tool-changing detection device is arranged at the edge of the upper guide rail body. Reliability of a tool magazine is greatly improved, production cycle is greatly prolonged greatly, and tool changing of the automatic tool changing device is completed through matching of the tool magazine and a spindle. The tool magazine is fixed and the spindle moves for tool changing, so that moving inertia of the tool magazine is reduced, the structure of the tool magazine is simplified, and tool changing control is simple and reliable.

Description

technical field The invention relates to a tool magazine, in particular to an automatic tool changing device. Background technique At present, the repeated positioning accuracy of domestic machine tool magazines is low; tool recognition and tool selection are unstable; the failure rate of cooperation with machine tools is high; and high processing and assembly processes are required. Contents of the invention In order to solve the above technical problems, an automatic tool changing device is provided. In order to overcome the defects in the background technology, the technical solution adopted by the present invention to solve the technical problems is: the automatic tool changer includes a column, and the column is fixed with an upper guide rail body and a lower guide rail body, and the upper guide rail body and the lower guide rail The body is connected up and down. The upper rail body and the lower rail body are sequentially connected to place links, toolholders and...
