The invention provides a CNC machine tool rotary table, including a main shaft, the main shaft is provided with a main shaft clutch on one side of the rotating gear, the main shaft clutch is used to separate and close the main shaft and the rotating gear, the fixture is installed on the auxiliary shaft, and the auxiliary shaft and The main shafts are connected by a transmission belt, and a steering gear for reversing is installed on the transmission belt. Limiting rolling wheels are arranged symmetrically on both sides inside the steering gear, and a plurality of adaptive wheels arranged in a line are arranged in an array on the circumference of the limiting rolling wheels; The invention avoids the different deformations of the transmission belts with different distances or different sizes when they are twisted, reduces friction loss, and can fix the relative position through the steering gear to maintain the position and deformation angle of the transmission belt when changing angles, so that the transmission belt has a relatively high speed when running. High stability, preventing jumping in the transmission, thus affecting the processing accuracy, and well protecting the wear of the transmission belt, increasing the service life, reducing equipment costs, and improving processing accuracy.
Description
technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a rotary table of a numerical control machine tool. Background technique [0002] The rotary table of CNC machine tool is a supplement to change the original processing part as the main shaft and does not move. The traditional CNC machine tool only moves the tool on the X-axis or Y-axis to process the parts. The disadvantage of this processing method is the rotation angle. limited, so there will be a movable turntable. At present, the turntable is mostly rotated by four axes, and two servo motors with mutually perpendicular axes are used to control the turntable rotating in two directions. This method can realize two The linkage and independent movement of each axis, this structure also increases the corresponding volume and cost. In the processing of small parts, the use of large-scale CNC machine tools is likely to cause waste of resources and waste of r...
