Problems solved by technology

In addition, the relatively large transmission ratio of the worm gear also limits the speed of the CNC turntable, resulting in the speed of the CNC turntable generally below 20 rpm, so the worm gear turntable is difficult to meet the high-speed and efficient processing requirements of CNC machine tools

Embodiment 1

[0029] This embodiment provides a precision workbench with double rotary shafts, see Figure 1-Figure 6 . The double rotary axis precision workbench of the present invention may refer to a workbench capable of rotating along the A axis and the B axis in a horizontal machining center. The dual-axis precision workbench of this embodiment includes a turntable 10 that can rotate along the B axis, and the turntable 10 that rotates along the B axis is used to place workpieces that need to be processed. The bottom of the rotary table 10 is installed in the cradle body 8 . Preferably, the middle of the cradle body 8 is used to install the rotary table 10, and the two ends of the cradle body 8 away from the rotary table 10 are respectively fixed with the A-axis main shaft 7 capable of rotating along the A-axis. Preferably, the cradle body 8 includes a middle cradle base 27 for installing the rotary table 10 and cradle arms located at two ends of the cradle base. Preferably, the crad...

Abstract

The invention relates to a double-rotation-shaft precision workbench. The double-rotation-shaft precision workbench comprises a rotation workbench capable of rotating along a B axis, the lower portionof the rotation workbench is arranged in a swinging basket body, and the two ends, away from the rotation workbench, of the swinging basket body are fixed to an A-axis main shaft capable of rotatingalong an A axis. The outer edge of the A-axis main shaft is connected with a first torque motor, wherein the first torque motor can drive the A-axis main shaft to rotate, and accordingly the swingingbasket body can be driven to do the rotation movement along the A axis. The outer side of a rotation shaft of the rotation workbench is connected with a second torque motor, wherein the second torquemotor can drive the rotation shaft to rotate, and accordingly the rotation workbench can be driven to do the rotation movement along the B axis. The double-rotation-shaft workbench is arranged along the A axis and the B axis, the torque motors are adopted for direct drive, the rotation coordinate axis of a horizontal machining center has high positioning precision, and since the torque motors areadopted for direct drive, the inner space can be sufficiently utilized, the height of a rotation table is reduced, and the whole rotation table structure is more compact.

Description

technical field [0001] The invention relates to the technical field of machine tool manufacturing, in particular to a precision workbench with double rotary shafts. Background technique [0002] Five-axis machine tools can be used to process many key parts with complex shapes, and have become the key basic equipment for the rapid development and realization of equipment manufacturing and advanced defense weaponry products. The workbench with dual rotary axes is an important structure for five-axis machining form. With the development of science and technology, the requirements for machining accuracy and effect are getting higher and higher, especially the requirements for machining position accuracy and dynamic accuracy are further improved. As an important functional component for multi-axis linkage, the CNC turntable can assist the A-axis spindle to complete high-precision five-sided machining. [0003] However, domestic traditional CNC turntables generally use a servo m...
