Description

Technical Field

[0001] The utility model relates to the technical field of numerical control processing equipment, in particular to a rotary worktable of a numerical control processing center. Background Art

[0002] The rotary table of the CNC machining center plays a vital role in the CNC machining process. It can rotate the workpiece to different angles as needed, allowing the machining tool to more easily contact and process different surfaces of the workpiece, ensuring that the workpiece can fully meet the machining requirements. It can also be adjusted according to the size and geometry of the workpiece, thereby achieving more flexible machining operations and further broadening the machining range of the machine tool.

[0003] When the rotary table of the existing CNC machining center is in use, the operator usually fixes the workpiece to be processed on the upper end of the rotary table of the CNC machining center through the corresponding clamp, and then the operator rotates the hand wheel to drive the workpiece to rotate through the cooperation of the hand wheel and the adjustment component, thereby adjusting the position of the workpiece, and finally the external equipment can process the workpiece through the tool;

[0004] The rotary table of the existing CNC machining center can drive the workpiece to rotate by the cooperation of the hand wheel and the adjustment component when working, but the operation is cumbersome and the workload of the personnel is relatively heavy. The rotary table of some CNC machining centers drives the workpiece to rotate by the cooperation of the worm wheel and the worm. This driving method can be self-locking and also improves the accuracy of the rotary table of the CNC machining center. However, the transmission efficiency of the worm wheel and the worm is low, and most of the lost power will be converted into heat. In addition, the worm transmission structure is compact and the heat dissipation area is small, resulting in poor heat dissipation capacity. If the generated heat cannot be dissipated in time, it will cause direct contact between the friction surfaces and the metal, aggravating friction and wear, and may even cause bonding, thereby reducing the working efficiency of the rotary table of the CNC machining center. For this reason, we propose a rotary table for a CNC machining center. Utility Model Content
