Problems solved by technology

On the one hand, this structure is complex, takes up a lot of space, requires high positioning accuracy, and high manufacturing costs; on the other hand, the process of tool change and preparation is complicated, and the speed of tool change is difficult to improve
At the same time, in order to prevent the tool changing robot arm from occupying the moving space of the workbench, the chain tool magazine is usually installed on the side of the machine tool, which may easily cause the center of gravity of the machine tool to shift, which has a great impact on the maintenance of machine tool accuracy; and the tool magazine occupies the side space of the machine tool , in the layout of automated production lines, the site utilization rate is low, which is not conducive to the layout of machine tool production lines
In addition, the asynchronous motor is used to drive the tool during the tool exchange process, and the buckle-type grasping tool is used. The tool change process is not controlled, and the impact force is large. Long-term tool change is likely to cause the loss of spindle accuracy and affect the overall processing performance of the machine tool.

Abstract

The invention relates to an integrated chain type tool magazine capable of automatically picking up and replacing tools, and aims to provide an integrated chain type tool magazine which is simple in structure, small in occupied space, low in manufacturing cost, high in tool replacing speed and small in tool replacing impact force. The integrated chain type tool magazine can be arranged right behind a machine tool, symmetrical arrangement of the machine tool is realized, machine tool precision loss caused by eccentricity is avoided, and an automatic production line is easy to arrange. The device is composed of a base, a chain mechanism, a chain driving unit, a tool replacing manipulator, a manipulator rotation driving unit, a manipulator moving push-out mechanism and a moving push-out driving unit, wherein the chain mechanism used for containing tools is arranged on the base and can rotate under the action of the chain driving unit; the tool replacing manipulator is installed on the base through the manipulator moving push-out mechanism, on one hand, push-out and returning linear reciprocating movement can be conducted under the action of the moving push-out driving unit, on the other hand, 180-degree rotation can be conducted under the action of the manipulator rotation driving unit, and tool position exchange is achieved.

Description

technical field [0001] The invention belongs to the field of numerical control machining, and in particular relates to an integrated chain tool magazine for self-picking and tool change. Background technique [0002] Due to its large capacity, the chain tool magazine has been more and more widely used in CNC machining centers. The existing chain-type tool magazine is mostly used with the tool-changing manipulator to realize tool exchange. The tool-changing manipulator and the chain-type tool magazine are designed independently. The tool-changing manipulator is located between the chain-type tool magazine and the machine tool spindle. The rotary motion of the manipulator arm completes tool removal, tool preparation and tool exchange. On the one hand, this structure is complex, takes up a large space overall, requires high positioning accuracy, and high manufacturing costs; on the other hand, the process of tool change and preparation is complicated, and the speed of tool cha...
