A Nested Tool Magazine for Numerical Control Machine Tool

Abstract

The invention discloses a nested tool magazine for a numerically controlled machine tool, which relates to the technical field of numerically controlled machine tools and includes an outer cutter head and an inner cutter head. The outer cutter head is provided with a plurality of first tool clamping mechanisms distributed in a ring. The cutter head has a loading and unloading position. By rotating the outer cutter head to make any first tool clamping mechanism on it reach the loading and unloading position, there is at least one avoidance space on the outer cutter head; Two tool clamping mechanisms, each second tool clamping mechanism can slide along the radial direction of the inner cutter head, the inner cutter head is rotatably set in the center of the outer cutter head, when the avoidance space is aligned with the loading and unloading position, by rotating the inner cutter head When any second tool clamping mechanism is aligned with the loading and unloading position, the second tool clamping mechanism can slide to the loading and unloading position. The invention can double the number of stored knives of the tool magazine without increasing the occupied space of the tool magazine, and can be directly adapted to the manipulator of the 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
