Problems solved by technology

[0003] In the precision CNC machining process, the use of the rotary table can greatly help the machine tool to process some complex surfaces. By making the table rotate, the workpiece can be adjusted without manual work. However, the rotation of the current precision CNC machine tool The workbench has the following problems: the current rotary workbench has the function of horizontal rotation, and the workpiece cannot be separated from the horizontal plane of processing, and it can be rotated or raised at an angle. observation, or take it out directly for observation, but the existing technology is not easy to solve such problems, therefore, there is an urgent need for a precision CNC machine tool rotary table to solve the above problems

Abstract

The invention belongs to the technical field of precision numerical control machine tools, particularly relates to a rotating table of a precision numerical control machine tool, and provides the following scheme aiming at the problem that an existing precision numerical control machining rotating table can only keep horizontal rotation: the rotating table comprises a fixed machine table, wherein a spherical groove is formed in the middle of the top of the fixed machine table; a horizontal hemispherical fixing block is fixed to the circumferential inner wall of the spherical groove in a sliding mode; a clamping groove is formed in the top of the circumferential inner wall of the hemispherical fixing block; and a horizontal rotary fixing top table is clamped to the bottom of the hemispherical fixing block through the clamping groove. A second driving motor drives a swing rack to move, the hemispherical fixing block can achieve spherical surface operation within the radius, the rotary fixing top table at the top leaves the horizontal plane, the multi-angle rotating process can be directly presented, in the workpiece machining process, various complex structure machining can be conducted on a workpiece in cooperation with cutting and a drill bit, and observation of operators can be more convenient.

Description

technical field [0001] The invention relates to the technical field of precision numerical control machine tools, in particular to a rotary table of precision numerical control machine tools. Background technique [0002] The machining accuracy of ordinary CNC machine tools has increased from 10 μm to 5 μm, and the precision machining center has increased from 3 to 5 μm to 1 to 1.5 μm, and the ultra-precision machining accuracy has begun to enter the nanometer level (0.01 μm). In terms of reliability , the MTBF value of the domestic numerical control device has reached more than 6000h, and the MTBF value of the servo system has reached more than 30000h, showing very high reliability. With the rapid development, the application field is further expanded. [0003] In the precision CNC machining process, the use of the rotary table can greatly help the machine tool to process some complex surfaces. By making the table rotate, the workpiece can be adjusted without manual work. ...
