Nested tool magazine of numerical control machine tool

Abstract

The invention discloses a nested tool magazine of a numerical control machine tool, and relates to the technical field of numerical control machine tools. The nested tool magazine comprises an outer cutter head and an inner cutter head, a plurality of first tool clamping mechanisms are annularly distributed on the outer cutter head, the outer cutter head is provided with a loading and unloading position, any first tool clamping mechanism on the outer cutter head can reach the loading and unloading position by rotating the outer cutter head, and at least one avoiding space is formed in the outer cutter head. A plurality of second tool clamping mechanisms are annularly distributed on the inner cutter head, each second cutter clamping mechanism can slide in the radial direction of the inner cutter head, the inner cutter head is rotationally arranged in the center of the outer cutter head in a sleeved mode, and when the avoiding space is aligned with the loading and unloading position, the inner cutter head is rotated to enable any second cutter clamping mechanism on the inner cutter head to be aligned with the loading and unloading position, and the second cutter clamping mechanism can slide to the loading and unloading position. According to the nested tool magazine of the numerical control machine tool, the number of stored tools of the tool magazine can be multiplied under the condition that the occupied space of the tool magazine is not increased, and the tool magazine can be directly matched with a mechanical arm of an existing numerical control machine tool.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a nested tool magazine for numerical control machine tools. Background technique [0002] CNC machine tool is an automatic machine tool equipped with a program control system, which can automatically process the workpiece by controlling the movement of the machine tool according to the shape and size required by the drawing. The CNC machine tool has a tool magazine for storing various tools, and the tool exchange of the CNC machine tool spindle is realized by grabbing the tool from the tool magazine through the control system and the manipulator. [0003] For example, the publication number is CN107283198A published on October 24, 2017, and the name is "A Disc Type Tool Magazine", which includes a motor, a rotating shaft is installed on one side of the motor, and the motor is installed on the mounting plate. The rotating shaft is connected to the turntabl...

Problems solved by technology

[0004] In the existing technology, with the improvement of the precision and complexity of workpiece processing, more and more tools need to be used in the machining process of CNC machine tools. The number of existing tool magazines has reached the upper limit, and it is imminent to expand the tool magazine.

However, the overall structure of the CNC machine tool is very compact, and the space occupied by the tool magazine is also very limited. If the conventional method of adding a new tool magazine or increasing the volume of the tool magazine is adopted, the modification of the CNC machine tool is relatively large, and the cost is relatively high. And it will cause the loading and unloading position of the manipulator to pick and place the tool to change, or even more than one loading and unloading position, which cannot be directly adapted to the manipulator of the existing CNC machine tool, and the limitations are very obvious
