Description

Technical Field

[0001] This invention relates to the field of technology, specifically to a tool magazine structure for multi-channel CNC machine tools. Background Technology

[0002] Multi-channel CNC machine tools are high-end CNC equipment with multiple independent or collaborative machining channels, capable of performing different machining tasks simultaneously on the same machine tool. They are suitable for the efficient and high-precision manufacturing of complex parts. These machine tools achieve integrated machining of multiple processes such as turning, milling, drilling, and tapping through multi-axis linkage, multi-task parallel processing, and intelligent control systems. The tool magazine structure for multi-channel CNC machine tools is an automated tool storage system specifically designed for multi-task, multi-channel CNC machine tools. It can efficiently manage a large number of tools to meet the continuous cutting needs of complex parts in multiple machining channels.

[0003] Patent CN219113495U discloses a disc-type tool magazine for CNC machine tools. When the rotary rod rotates, it drives the extrusion rod to rotate around the center of the rotary rod until the extrusion rod contacts the hydraulic rod and they extrude against each other. This causes the hydraulic rod to be stressed, pushing the hydraulic plate to slide to the right along the inner wall of the hydraulic chamber. The hydraulic oil is squeezed and enters the discharge ring through the pipe. The oil then exerts a force on the slide plate, causing the slide plate to slide outward along the inner wall of the discharge ring. The cleaning agent is squeezed and sprayed onto the tool through the discharge hole, thereby cleaning the tool and improving the quality of the workpiece processed by the tool. However, when using this tool magazine structure, it can usually only accommodate a small number of tools at the edge position, resulting in relatively low space utilization and being detrimental to long-term economic benefits. Therefore, we propose a tool magazine structure for multi-channel CNC machine tools. Summary of the Invention

[0014] As a further aspect of the present invention: a rotary motor is fixedly installed in the middle of the lower side of the bearing base, and the rotating shaft is fixedly connected to the output end of the rotary motor. An annular groove is provided on the bearing base, and the movable ring plate is located inside the annular groove.

This, in conjunction with the driven gear plate on the outside of the driven shaft, drives the chain belt for transmission, which in turn drives the connecting belt for transmission, until the second tool holder is located at the second tool changing port for tool changing. At the same time, the rotation of the main gear plate and the driven gear plate will drive several sets of first tool holders to rotate together until the first tool holder is located at the first tool changing port for tool changing. This maximizes space utilization, allowing more tools to be accommodated for tool changing operations, and is more cost-effective in the long run.

[0019] 2. By starting the rotary motor in the middle of the support base, the rotating shaft is driven to rotate, which in turn drives the rotating groove to rotate under the cooperation of the movable ring plate and the annular groove. This, in turn, drives the support vertical plate to rotate, and the position of the rotating groove is fixed by the first fastening bolt. Next, the translation motor at the outer end of the rotating groove is started to drive the horizontal lead screw shaft to rotate. This, through the threaded connection between the horizontal lead screw shaft and the moving block, drives the vertical groove to move laterally, which in turn drives the support vertical plate to move laterally. The position of the vertical groove is fixed by the second fastening bolt on the first connecting plate. Immediately afterwards, the lifting motor at the top of the vertical groove is started to drive the vertical lead screw shaft to rotate. This, through the threaded connection between the vertical lead screw shaft and the lifting block, drives the support vertical plate to rise and fall, and the position of the support vertical plate is fixed by the third fastening bolt on the second connecting plate. This realizes the position adjustment function of the tool magazine structure, so as to be suitable for tool changing operations of multi-channel CNC machine tools. Attached Figure Description
