Bamboo hat type double-layer tool magazine

Abstract

The invention discloses a bamboo hat type double-layer tool magazine which comprises a tool disc, a tool disc driving mechanism and a tool disc rotation detection mechanism. Two layers of tool positioning assemblies which are in up-down symmetry are arranged on the tool disc, and each layer of tool positioning assembly comprises a plurality of clamping jaws which are arranged on the peripheral wall of the tool disc and distributed in a circumferential array mode; and each clamping jaw is matched with the mounting and fixing of one tool. Compared with the prior art, according to the provided bamboo hat type double-layer tool magazine, under the condition that the diameter of an existing tool disc is kept, the tool disc can meet the requirement for installation of an upper layer tool positioning assembly and a lower layer tool positioning assembly only by properly increasing the thickness of the tool disc, the two layers of tool positioning assemblies are mutually symmetrical and compactly arranged, interference with other mechanisms of a turning and milling composite machine tool is avoided, the number of storable tools is doubled, 32-40 tools can be stored at most, the number of the tools is large, the machining requirement of the turning and milling composite machine tool is well met, and the problem of manual tool changing is solved.

Description

technical field [0001] The invention relates to the field of numerical control machine tool equipment, in particular to a hat-type double-layer tool magazine. Background technique [0002] The tool magazine is an important functional part of the CNC machining center. It not only has the ability to store tools, but also accurately sends the tools needed by the machining center to the tool changing position, and through the automatic tool changing device or the cooperation between the tool magazine and the spindle. Swap the subsequent process tool with the previous process tool on the spindle. Common tool magazine types include disc magazine, chain magazine and hat magazine. The hat-type tool magazine is often used in small and medium-sized machining centers, and its tool change action is completed by the tool magazine action and the spindle action. When changing the tool, the spindle stops and lowers the tool in the previous process to the specified height, the empty claws ...

AI Technical Summary

Problems solved by technology

[0003] The number of tools that can be loaded in the existing hat-type tool magazine is small. If the number of tools is to be increased, the diameter of the tool head will generally be enlarged, which takes up a lot of space and is likely to interfere with other components.

Or on the basis of having a bamboo hat-style tool magazine, add a bamboo hat-style tool magazine. Although the number of automatic tool change tools in the CNC machining center is doubled, it will increase the manufacturing cost on the one hand, and it will also increase the production cost. Occupies a lot of space, it is necessary to solve the problem of the rationality of the placement of the two magazines
