Description

Swash plate tool magazine, tool claw and driving device Technical Field The invention relates to the technical field of machining equipment, in particular to a swash plate type tool magazine applied to a numerical control machine tool (particularly a machining center), a tool claw for the tool magazine and a driving device for driving the tool magazine. Background The tool magazine is one of core components of an automatic machine tool such as a machining center, and is used for storing tools and automatically exchanging the tools according to machining program instructions. The swash plate type tool magazine is widely applied to various small and medium-sized machining centers due to the characteristics of compact structure, high tool changing speed and the like. The swash plate tool magazine and the driving device thereof in the prior art mainly have the following defects: The existing tool magazine holding arms are integrated in structure or are complex in connection mode, when the tool claw is worn or damaged due to long-term use, a large number of relevant parts are required to be disassembled for replacement, the maintenance cost is high, the downtime is long, in addition, the clamping force of part of the holding arms is not adjustable or inconvenient to adjust, tools with different weights and types are difficult to adapt, and the stability and reliability of tool changing are affected; The driving device is unreasonable in layout and low in transmission efficiency, the driving device of the existing tool magazine usually adopts a motor to drive the tool magazine turntable to rotate through an intermediate transmission mechanism such as a belt or a gear, the layout is complex in structure and large in occupied space, transmission errors and energy loss can be introduced due to the existence of intermediate transmission links, the transmission efficiency and the accuracy of tool changing positioning are reduced, and meanwhile, a complex supporting structure is often required for a connection mode of the motor and the turntable, so that the weight and the installation difficulty of the whole tool magazine system are increased.
