Novel numerical control machine vertical rotating table

Abstract

The invention provides a novel numerical control machine vertical rotating table, comprising a base, a rotating shaft, an operating platform and a rotary driving device. The rotating shaft is rotatably arranged on the base, the operating platform is fixedly arranged at the top of the rotating shaft, the rotary driving device is arranged between the base and the rotating shaft and is used for driving the operating platform to rotate, the base is uniformly provided with two to eight hinge lever clamping mechanisms along the peripheral direction, the lower surface of the operating platform is provided with conical blocks with the same quantity of corresponding hinge lever clamping mechanisms, when the operating platform is at each processing station, the hinge lever clamping mechanism clampsthe conical blocks, the accuracy of a workpiece processed by the rotating table is high, the surface roughness of the workpiece is low, and the rotating table is beneficial to prolonging the service life of a cutter.

Description

technical field [0001] The invention relates to a numerically controlled machine tool, in particular to a novel vertical rotary table of the numerically controlled machine tool. Background technique [0002] refer to figure 1 , the known vertical rotary table for CNC machine tools generally includes a base 1', a vertical rotary table and a rotary drive device, the base 1' is used to fix and support the vertical rotary table and the rotary drive device, the vertical The rotary table includes a rotating shaft 2' and a table 3', the rotating shaft 2' is rotatably arranged on the base 1' through a bearing, the table 3' is arranged on the top of the rotating shaft 2', and the rotary drive device includes a drive motor 4' reducer 5' drive wheel 6' and driven wheel 7', the drive motor 4' is located on the base 1', the input end of the reducer 5' is connected to the output end of the drive motor 4', the reducer 5 The output end of ' is connected with the driving wheel 6' through t...

AI Technical Summary

Problems solved by technology

The disadvantage of the known vertical rotary table used for CNC machine tools is that when the CNC machine tool is in the state of processing workpieces, since the tool exerts a certain force on the workpiece, the workbench 3' for fixing the workpiece may on the one hand Deformation occurs, on the other hand, vibration occurs. The deformation or vibration of the table 3' will lead to low machining accuracy of the workpiece, high surface roughness, and shortened tool life due to vibration. This is the deficiency of the existing CNC machine tool vertical rotary table place
