A chain type tool magazine with automatic loosening and tightening mechanical claws

Abstract

The invention discloses a new type of chain tool magazine with automatic loosening and tightening mechanical claws, which includes a skeleton, a driving shaft, a driving sprocket, a driving motor, a fixing box, an exchanging arm, an exchanging motor, a conveying chain and an exchanging device. A driving shaft and a driven shaft are connected through bearing rotation, one end of the driving shaft is fixedly connected with a driving sprocket, one end of the driven shaft is fixedly connected with a driven sprocket, and the outer side of the skeleton is covered with a conveyor chain. Both sides of the chain are fixedly connected with embedded blocks, the driving sprocket and the driven sprocket are matched with the embedded blocks, the driving sprocket is connected with the driven sprocket through the transmission chain, and the outer side of the conveyor chain is equidistant The knife claw is fixedly connected, and the side of the skeleton far away from the drive sprocket is fixedly connected with a fixed box and a drive motor. This device is convenient and quick when picking up the tool, and is simple and convenient when changing the tool. It saves manpower and improves work efficiency. The presence of personnel brings convenience.

Description

technical field [0001] The invention relates to the technical field of chain tool magazines, in particular to a novel chain tool magazine with automatic elastic and tightening mechanical claws. Background technique [0002] The chain tool magazine is a form of tool magazine in CNC machine tools. It has a large tool capacity, but the positioning accuracy of the tool magazine is low. Compared with the disc guide rail, the chain tool magazine has the advantage of large tool capacity, but the chain structure of the traditional chain tool magazine: the tool is equivalent to being placed on the chain, and the chain needs to move back and forth, so there is no way to achieve the rigidity of the entire chain Support; that is to say, for the chain tool magazine, the chain is both a load-carrying system and a transmission system, which determines that there are obvious defects in the chain tool magazine: poor mechanical rigidity and large transmission gap, which cause the positioning ...

[0002] The chain tool magazine is a form of tool magazine in CNC machine tools. It has a large tool capacity, but the positioning accuracy of the tool magazine is low.

Compared with the disc guide rail, the chain tool magazine has the advantage of large tool capacity, but the chain structure of the traditional chain tool magazine: the tool is equivalent to being placed on the chain, and the chain needs to move back and forth, so there is no way to achieve the rigidity of the entire chain Support; that is to say, for the chain tool magazine, the chain is both a load-carrying system and a transmission system, which determines that there are obvious defects in the chain tool magazine: poor mechanical rigidity and large transmission gap, which cause the positioning of the tool magazine Poor accuracy; in order to improve positioning accuracy, complex detection and control circuits are required to achieve fast and accurate positioning

[0003] The existing chain-type tool magazine is not convenient enough to pick up the tools. It takes time and effort to pick up the tools manually, which reduces work efficiency.

[0004] The existing chain-type tool magazine is inconvenient when changing tools, and there are many steps, and the tool can only be taken and placed, but the tool cannot be replaced. Therefore, we propose a new type of chain-type tool magazine with automatic elastic mechanical claws
