Description

Technical Field

[0001] The utility model relates to the technical field of processing heads, in particular to a Y, Z-axis processing head structure. Background Technique

[0002] A numerical control machine tool, abbreviated as a CNC machine tool, is an automated machine tool equipped with a program control system. This control system can logically process a program with control codes or other symbolic instructions, decode it, represent it in coded numbers, input it into the numerical control device through an information carrier, and after arithmetic processing, the numerical control device issues various control signals to control the actions of the machine tool. According to the shape and size required by the drawing, the parts are automatically processed by the processing head.

[0003] The original Y-axis movement of the existing processing head is carried out on a fixture (moving platform), that is, the product to be processed is moved, and the spindle only makes Z-axis movement. That is, originally, the product moves in the XY axes through the fixture (moving platform). Since the fixture (moving platform) has the moving functions of both the X and Y axes, the lower moving platform has two-axis movement, which will lead to excessive error accumulation during the processing. That is, when making X-axis movement, it also makes Y-axis movement at the same time, resulting in a slight deviation in the position of the X-axis movement. For the processing of some high-precision parts, its accuracy is low and does not meet the standard. Summary of the Invention
