Modular structure chain type tool magazine and automatic tool change control method

Abstract

The invention provides a modular structure chain type tool magazine and an automatic tool change control method; the modular structure chain type tool magazine compriess a machine frame, a main controller, a linear mechanism, an ATC automatic tool change mechanism, an ATC translation motor and a virtual main shaft, wherein the ATC automatic tool change mechanism comprises an ATC motor and a cutterarm driven by the ATC motor to change the tool; a plurality of sub-module tool magazines are arranged on the machine frame in the movement direction of the ATC automatic tool change mechanism on thelinear mechanism; an independent servo motor, a sensing mechanism and a unit controller are arranged in each sub-module tool magazine; the unit controllers in the sub-module tool magazines are connected with a main controller circuit through a bus interface and a field bus respectively; and each submodule tool magazine is independently controlled by the main controller. With reasonable structure design, the tool magazine provided by the invention can solve the problem of large capacity of the tool magazine effectively under the condition of ensuring transmission stability, precision and structural rigidity; and the tool change efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of chain tool magazine design, in particular to a chain tool magazine with modular structure and an automatic tool change control method. Background technique [0002] The tool magazine system is a device that provides the tool storage and tool change requirements required in the automated machining process. The structure of the tool magazine and the tool change method are directly related to the processing range and work efficiency of the machine tool. With the development of social science and technology, the function and efficiency of machine tools have been improved, and the requirements for tool magazine capacity and tool change speed have also been continuously improved. [0003] At present, the traditional chain tool magazine mostly uses a single chain to arrange as many tools as possible to maximize the number of tools. However, the chain is used as a load-bearing structure and also as a transmissio...

Problems solved by technology

However, the chain is used as a load-bearing structure and also as a transmission mechanism. Blindly increasing the length of the chain will increase the load of the chain, reduce the rigidity of the structure, affect the service life, reduce the stability and precision of the transmission, and at the same time, the overly complicated structure also leads to the shortening of the tool change time.
