Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tools, specifically a high-precision CNC lathe that is easy to change cutting tools. Background Technology

[0002] CNC machine tools are machine tools that use computer programs to control machining operations. Compared with traditional machining methods, CNC machine tools rely on pre-programmed digital programs to precisely control every action in the machining process, including parameters such as position, speed, and acceleration. CNC machine tools are widely used in modern manufacturing, especially in mass production, high-precision parts machining, and complex surface machining, where they have irreplaceable advantages.

[0003] According to application number 202221992433.6, a high-precision CNC lathe that facilitates tool replacement is disclosed, including a front-rear adjustment assembly, an up-down adjustment assembly above the front-rear adjustment assembly, a left-right adjustment assembly on the up-down adjustment assembly, and a tool assembly on the left-right adjustment assembly. The front-rear adjustment assembly, up-down adjustment assembly, and left-right adjustment assembly can perform precise positioning adjustments on the entire machine to avoid misalignment of the parts being cut, which would affect sales. When it is necessary to change tools for work, the components set in the tool assembly allow the operator to quickly and easily remove the tool and replace it with another tool. The whole process is simple and easy to operate.

[0004] Existing technology has effectively solved the problem of the cumbersome process of disassembling and replacing tools using bolts, and the frequent misalignment between the work platform and the tool during cutting, resulting in defective parts.

Then rotate the threaded rod 605. By rotating the threaded rod 605, the height of the pressing block 606 inside the tool body 5 can be adjusted, so that it moves upward inside the tool body 5. After the pressing block 606 moves upward, it can gradually release the pressing state on the positioning post 602. At this time, the first spring 608 gradually returns to its original position. The return force of the first spring 608 can drive the positioning post 602 to return to its original position and move it out from the inside of the positioning hole 604. At this time, the tool body 5 can be removed from the inside of the mounting block 4. After removal, replace it with a new tool body 5, and then reverse the above operation to reinstall it.
