Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a tool head fixing component for numerically controlled lathes. Background Art

[0002] In the field of CNC lathe processing, the tool head fixing assembly is a key component to ensure processing accuracy and efficiency. The existing tool head fixing assembly usually adopts a rigid connection method. Although the structure is simple, it cannot realize the function of the tool head moving according to a specific arc. This limitation leads to the need to frequently replace the tool head or adjust the machine tool parameters when processing complex curved contours, which reduces processing efficiency and increases operation difficulty. Therefore, the development of a tool head fixing assembly for CNC lathes that can enable the fixed tool head to move according to a certain arc has important practical application value and market demand.

Figure 3When the installation method is used, the inner circle of the round rod product can be processed, and the cutter head can also be used in conjunction with the rotating fork to perform curved surface processing on the side of the round rod;

[0006] This device can fix the cutter head in various forms. Through ingenious structural design, the fixed cutter head can move according to a preset arc trajectory, thereby improving the accuracy and efficiency of processing complex curved contours.
