Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tools, and more specifically, particularly relates to a turntable structure of a numerical control machine tool. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, various control signals are sent by the CNC device to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing. The turntable is the working table of the machine tool, which can be rotated to any position and fixed in that position, also known as the "rotating table". The CNC turntable is a mechanical worktable that can rotate around the vertical axis and the horizontal axis at the same time, referred to as the PT turntable.

[0003] Today's CNC machine tools generally use a five-axis turntable. Due to its compact structure, the five-axis turntable can easily cause the side of the workpiece to touch the bottom when flipping an irregular workpiece 90 degrees, thereby causing damage to the workpiece. In addition, since the space between the existing five-axis turntable base and the bottom plate is relatively narrow, the waste chips generated by processing are not easy to clean, which can easily interfere with the processing process.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a turntable structure of a CNC machine tool is provided, in order to achieve a more practical purpose. Utility Model Content

[0016] The turntable structure of the CNC machine tool in the utility model drives the active bevel gear to rotate by a rotating motor, thereby causing the driven bevel gear to drive the lead screw to rotate, and then the movement of the slider 2 on the lead screw causes the baffle to move, thereby causing the connecting rod and the scraper to move, so that the end surface of the bottom plate can be cleaned by the scraper, thereby preventing waste chips from interfering with the machining process.
