Description

Technical Field

[0001] The utility model relates to the technical field of lathe tool installation, in particular to a CNC lathe tool installation structure. Background Art

[0002] A CNC lathe is a machine tool that uses a computer control system to achieve automated processing. According to a pre-set processing program, a CNC lathe can automatically control the movement of the tool and the processing process, thereby achieving high-precision and high-efficiency processing operations. A rectangular tool holder is a commonly used tool mounting device, which can be controlled by program instructions to rotate the rectangular tool holder to achieve tool change operations.

[0003] Currently, when installing a tool in a rectangular tool holder, the tool is installed on the tool holder of the lathe, and then the height of the tool tip is adjusted to align with the axis of the lathe spindle by adding or removing shims at the bottom of the tool. After adjusting the height of the tool tip, the tool is firmly fixed to the tool holder using bolts or clamping devices to ensure that the tool does not move or shake during processing; then an inspection is performed to ensure that the height of the tool tip is aligned with the axis of the lathe spindle, and the tool is firmly installed without looseness or offset. This completes the installation operation of the tool.

[0004] However, the current tool installation method still has the following shortcomings:

[0005] When adjusting the tool height by shims, it is necessary to first measure the height position of the tool, and then fine-tune the height of the tool by adding or reducing the placement of shims. After the adjustment is completed and the tool is fixed and installed, it is necessary to measure again to check the height, which makes the entire installation process more cumbersome. In addition, the support height of the shim after being pressed and the support height before being pressed may vary, which increases the difficulty of fine-tuning the tool tip height.
