Multi-spindle tool replacement system and method

Abstract

The invention relates to a multi-spindle tool replacement system and method. The system is arranged on a multi-spindle machining tool, the multi-spindle machining tool comprises a machine table, and multiple spindles arranged on the machine table, the spindles can be moved to the tool replacing position of a replacement tool, and the multi-spindle tool replacement system comprises a fixed tool rest and a first moving tool rest; the fixed tool rest is provided with multiple rows of rest bodies, and each rest body is provided with multiple tool rest bases allowing tools to be clamped, the firstmoving tool rest comprises a moving mechanism with moving capacity in the three-dimensional space direction and a rod body arranged on the moving mechanism, the rod body is provided with at least onetaking and putting unit, through moving of the rod body, the taking and putting units are linked, and the taking and putting units take or put back the tool arranged on the fixed tool rest. The movingpath of the taking and putting units comprises the corresponding position of all rest bodies of the fixed tool rest, a tool replacement waiting position close to a tool changing position of the multi-spindle machining tool and the tool changing position of the multi-spindle machining tool. The multi-spindle machining occasion can be subjected to tool changing, and personal operation is reduced.

Description

technical field [0001] The invention relates to a multi-spindle tool changing system and a method thereof. Background technique [0002] Existing processing machine tools, such as CNC milling machine tool change systems can be divided into arm type, clamp arm type, bucket hat type, row tool type, etc. according to the type of tool magazine. There are various tool change systems, but these tool change systems are all for a single spindle, that is to say, the spindle is in a one-to-one situation when changing tools, and it is impossible to achieve a one-to-many situation. Generally, in the case of multiple spindles with more than 2 spindles, there is basically no CNC milling machine with a tool change system. In the absence of a tool change system, it takes a lot of manpower to change the tool during processing. To replace each knife, it is more likely to be dangerous in operation when manually changing the knife, resulting in personal injury and work-related accidents. [0...
