Tool storage mechanism of numerically controlled drilling and milling machine

Abstract

The invention relates to a mechanism for storing spindle tool shanks on a numerically controlled drilling and milling machine, in particular to a tool storage mechanism of a numerically controlled drilling and milling machine. The tool storage mechanism is characterized in that a tool holder is fixedly mounted on an upper mounting surface and a lower mounting surface of a bracket respectively; a bushing is arranged between the upper and lower tool holders; multiple sets of clamping devices are arranged in parallel between the upper and lower tool holders; each set of clamping devices is formed by combining two single clamping devices; the middle part of each single clamping device is hinged between the upper and lower tool holders through a hinge pin shaft; the tool storage mechanism is also provided with an edge extension spring and a middle extension spring; one end of the edge extension spring is connected to the bracket; and the other end of the edge extension spring is connected with the upper end parts of the single clamping devices on the edges at the left and right ends of the tool holders. The tool storage mechanism provided by the invention is more reasonable in structural rigidity, arrangement mode, adjustment mode and manufacturability, has high operation stability and reliability, can ensure space precision and stability of the tool shanks, and remarkably improves the usability and service life of the tool storage.

Description

technical field [0001] The invention relates to a mechanism for storing a spindle tool handle on a numerical control drilling and milling machine, in particular to a tool magazine mechanism of a numerical control drilling and milling machine. Background technique [0002] In the prior art, similar products generally do not have a tool magazine and an automatic tool change mechanism, and all use manual tool change, which takes a long time for tool change assistance in the processing process, and the labor intensity of workers is high, and the production efficiency is low. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a tool magazine mechanism for a CNC drilling and milling machine with convenient tool change structure, accurate positioning of multi-tool stations, reliable tool change and long service life. [0004] According to the technical solution provided by the present invention, the ...
