Abstract

The invention relates to the technical field of machining, and discloses a tool changing and locking structure and an automatic machine tool. The tool changing and locking structure is used for locking tools in a tool storeroom when the tools are released by a main shaft; the tool storeroom comprises a base; the base is provided with multiple tool locations which are used for enabling the tools to vertically insert and place. The tool changing and locking structure comprises clamping parts which are arranged at the middle parts of the tools, a tool locking plate which is arranged above the base and can horizontally slide relative to the base, and a tool locking driving piece which is used for driving the tool locking plate, wherein locking structures which can be used for clamping the clamping parts along with the moving of the tool locking plate are arranged in positions, which correspond to the tool locations, of the tool locking plate. According to the tool changing and locking structure disclosed by the invention, the tool locking plate moves transversely when the main shaft descends to release the tools, and the clamping parts of the tools can be clamped by utilizing the locking structures, so that the tools cannot ascend along with the main shaft, tool releasing can be completed, and the problem that tool collision damage is caused as the main shaft does not fall off cannot happen.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a tool changing locking structure and an automatic machine tool. Background technique [0002] In modern machining, automatic machine tools can complete automatic tool change, multiple processing, and complete multiple processing steps fully automatically. In the process of tool change, the spindle needs to move and align the tool to the tool position of the tool magazine, descend to insert the tool into the tool position, release the tool, the tool falls into the tool position, and then the spindle rises and moves to align to other tool positions , descending again to insert the required tool holder into the spindle, clamping and rising to complete the tool change process. [0003] Although this tool change method can cope with most machine tool changes, in ultra-precision machining machine tools, because the small tools used, such as φ3, φ5, etc., have a small weight, the ir...
