This invention belongs to the field of machine tool accessories technology and discloses a water-cooled CNC lathe tool holder, including a frame. A servo motor is fixedly installed on the left side of the frame, and a tool holder is fixedly installed at the output end of the servo motor. The outer side of the tool holder has slots at equal angles, and CNC tools are movably engaged within each slot. An extension frame is fixedly installed at the front end of the servo motor, and a tool mounting bracket located directly in front of the slots is fixedly installed on one side of the extension frame. This invention utilizes externally input high-pressure water during water cooling. Through the action of the high-pressure water, the device can automatically lock unused tools during tool changing and tool installation, preventing tool displacement. The entire process can be completed automatically before tool changing, effectively avoiding the probabilistic tool collision problem that can still occur during tool changing and tool installation in traditional devices, thus reducing safety hazards.

According to the multi-station tool taking mechanical arm, the X-axis moving mechanism is used for horizontally moving the moving table, the moving table is fixedly provided with the tool taking mechanism and the tool changing mechanism, during operation, the Z-axis moving mechanism ascends by a certain height firstly, the height of the clamping mechanism is slightly higher than that of the tool rotating table, the telescopic air cylinder retracts, the rotating air cylinder is started to rotate by 90 degrees, and the tool taking mechanism and the tool changing mechanism are fixed. The clamping mechanism is aligned with the cutter on the cutter rotating table, a clamping head of the clamping mechanism is opened, the telescopic air cylinder stretches out, then the cutter is clamped by the clamping mechanism, at the moment, the Z-axis moving mechanism moves upwards, the cutter is pulled out of the cutter fixing hole, then the telescopic air cylinder retracts, the rotating air cylinder rotates reversely by 90 degrees, and the Z-axis moving mechanism descends; the tools are taken to the machining equipment, one tool changing mechanism is arranged beside each tool taking mechanism, the tools can be conveniently and rapidly taken by the tool taking mechanisms, and the tool changing speed is increased.

The present application relates to the technical field of tool magazine, and particularly relates to a precision ring guide rail type tool magazine, which comprises a bottom plate, a chain, a guide rail, a trolley assembly and a tool holder, the tool holder and the trolley assembly are relatively fixed, the trolley assembly slides on the guide rail through first rollers, and the trolley assembly is driven to move by the chain, the present application drives the sprocket to rotate by a first driving mechanism, drives the chain to rotate circularly, drives the trolley assembly to slide on the track by the chain, the driving trolley is positioned in a V shape by four first rollers, is rigidly arranged on the track, avoids the problem that the traditional chain type tool magazine is easy to be loose, and can improve the tool changing speed, improve the stability of transmission, improve the rigidity of the trolley assembly through the setting of universal balls, second rollers and third rollers, and further set a positioning mechanism to improve the positioning accuracy of the tool magazine.
