Description of the Invention: [Technical Field] The present invention belongs to a knife storage technology of a numerically controlled processing machine, and specifically refers to a multi-layer automatic tool change system with a high speed and a large amount of knives. It can quickly change the purpose of the knife, and further improve its processing efficiency. [Prior Art] Press, in order to improve the processing efficiency and precision, the numerical control processing machine has become the mainstream of the cutting machine, so the processing form is also constantly refurbished, in addition to the traditional drilling, milling, turning, but also the attack Tooth, grinding, positioning and image taking, etc., and a variety of different processing styles and different sizes in the same processing form, so there are a lot of tools to be prepared. Therefore, the numerical control processing machine usually has a tool change tool magazine for mounting various types of cutting tools, and the traditional tool magazine is mainly composed of a rotary tool magazine or a chain magazine, which is attached to the turntable or the chain. The upper equidistant space is provided with a plurality of knife sleeves for inserting tools, and the tool magazine is provided with a rotatable tool change device at a fixed point for synchronously extracting, rotating and embedding between the tool spindles of the tool magazine and the processing machine by using the tool change device. Inserting, and achieving the purpose of tool change; however, the existing tool magazine, regardless of the rotary type or the chain type tool magazine, has a limited amount of preparation for space and operation considerations, so the general operator controls the value. The machine does not turn into a special processing machine for a single product, in order to reduce the processing requirements of the tool in the case of the eve, the same day, that is, the need to update the entire tool magazine with 5 1353281 knife, so need to re-align the tool and correct, will Significantly increase the time of tool change, which affects the efficiency of processing, so further improvement is needed. In other words, how to increase the tool preparation 4 of the tool magazine without affecting the tool change action and waiting time, the elevator can be applied to a small number of multi-machining workpieces to meet different processing needs. And improve the efficiency of its processing and production. In view of this, the present inventors have focused on the problem of the existing numerical control training case, the problem of the knife and the amount of the knife; and the experience of research and development and manufacturing of related industries for many years, actively seeking solutions. Through continuous research and trial work, 'finally successfully developed a multi-layer automatic tool change (4), to solve the inconvenience and trouble of the existing numerical control processing machine for small, multi-pattern processing workpieces. SUMMARY OF THE INVENTION A multi-layer automatic tool change system effectively improves the processing of a small amount of machining
