Description

Technical Field

[0001] The utility model relates to a machine tool operation matching piece with an automatic tool changing function, in particular to an inverted layout of a machine tool tool magazine. Background Art

[0002] The classification of machine tool tool magazines is mainly based on their structural form and functional characteristics, and mainly includes three types: conical type, disc type and chain type.

[0003] The ‌conical hat-style tool magazine is named for its shape similar to the conical hat of ancient warriors. It is usually located on the top of the machine tool and realizes the selection and positioning of tools through a rotating and lifting mechanism. The tool changing process of the conical hat-style tool magazine is relatively simple, but due to the structure, the tool capacity is limited, generally not more than 24 pieces, and the tool changing time is long, which may not be efficient for complex processing tasks that require frequent tool changes.

[0004] The ‌disc-type tool magazine‌ is one of the most widely used types of tool magazines. It adopts a horizontal or inclined disc structure, and the tools are evenly distributed on the disc. The tool selection is achieved through rotation and translation. The disc-type tool magazine has the advantages of large capacity, fast tool change speed, and high positioning accuracy, which can meet most processing needs.

[0005] Chain tool magazines use chains or trays driven by chains to store tools, and the selection and replacement of tools is achieved through the circular motion of the chain. This tool magazine has a flexible structure, can accommodate tools of different lengths, and has a large tool capacity. However, the structure of the chain tool magazine is relatively complex, and the precision requirements of the chain and transmission system are relatively high, and the maintenance cost is relatively high.

[0006] From the above, we can see that each type of machine tool tool magazine has its specific advantages and application scenarios, but these three types of machine tool tool magazines are placed with the tool facing down and the tool handle facing up, so the tapered part of the tool handle is easily contaminated by dust.
