Quick-change drawer tool magazine

Abstract

The invention discloses a quick-change drawer tool magazine. The quick-change drawer tool magazine comprises a tool magazine sliding table used for moving the tool magazine and a plurality of drawer units connected to the tool magazine sliding table. The drawer units comprise brackets and knife holders movably connected with the brackets, and the knife holders can be rapidly and safely replaced in a non-working state. According to the quick-change drawer tool magazine, the tool magazine can move in the non-working state of a machine tool main shaft, the whole tool magazine replacing process is carried out outside the machine tool, and compared with tool replacing operation carried out in a tool working area in the machine tool in the prior art, the safety of the tool replacing operation environment is improved; and the brackets and the cutter holders form a drawer structure, the cutter holders can be integrally replaced, the replacement speed is high, the shutdown cutter replacement time is shortened, the utilization rate of the machine tool is improved, the cutter replacement frequency is reduced, the service life of the main shaft is prolonged, and the cutter holders can be conveniently and thoroughly cleaned offline.

Description

technical field [0001] The invention relates to the field of numerical control machine tools, in particular to a quick-change drawer magazine. Background technique [0002] Multi-spindle machine tools are generally equipped with a tool magazine, which is convenient for the machine tool to use corresponding tools for processing according to different processing requirements. For changing the tool from the tool magazine, tools or labor are generally used to directly load and unload the tool holder in the tool magazine, but only one tool holder can be loaded and unloaded at a time. Loading and unloading a large number of tool holders is time-consuming and laborious, and will also affect the utilization rate of the machine tool . At present, machine tool magazines are generally used, including umbrella tool magazines, disc tool magazines, chain tool magazines, matrix tool magazines, etc., and the tool holders can be replaced directly in these tool magazines. The operable space ...

AI Technical Summary

Problems solved by technology

Although this method of assembling and disassembling tool handles by one installation and one disassembly is logically more rigorous and reliable, when there are many tool handles, especially for multi-spindle machine tools, when the number of tool handles reaches tens of hundreds, it will be time-consuming and laborious. The machine tool has a long downtime, which seriously affects the utilization rate of the machine tool, and the spindle and manipulator frequently install and remove tools in a short period of time, which also affects the life of the spindle and manipulator

[0004] In the above existing schemes, the layout in the tool magazine is a plug-in tool handle socket (knife holder), which is generally fixedly arranged on the tool magazine, and the tool holder is used to install the tool handle. When pollutants are brought in by the way, such as chips and cutting fluid mixture, these pollutants are easy to stick to the tool holder, and then stick to the tool holder, which will cause poor accuracy when the tool holder in the tool magazine is loaded into the spindle, and even change the tool. fail

These pollutants stick to the tool seat for a long time, making it very difficult to clean
