Description

Technical Field

[0001] This utility model relates to the field of CNC machining tools, specifically a double-support five-axis precision rotary table. Background Technology

[0002] With the development of industrial manufacturing, the demand for CNC machining centers is also increasing, especially four-axis and five-axis linkage machining centers. As the main equipment of CNC machine tools, the CNC rotary table plays an increasingly important role in the entire machine tool. The emergence of CNC rotary tables provides rotary coordinates for machining centers and CNC milling machines. By driving the rotary table or indexing head through the fourth and fifth axes, it can complete the machining of equal, unequal, or continuous precision angles, and complete the machining of complex curved surface workpieces, thus expanding the machining range of machine tools. In existing technologies, after prolonged use of five-axis rotary tables, due to their high internal integration and tight fit of components, heat dissipation performance is generally poor, often resulting in significant internal heat generation. This can lead to high internal temperatures and reduced lifespan of the five-axis rotary table. One CNC machine tool five-axis rotary table, as described in application number "CN202222944406.8", achieves heat dissipation by using a combination of a five-axis rotary table, bolts, fixing holes, L-shaped plates, fixing pipes, a first support plate, and a drive motor, thereby reducing the internal temperature and extending the lifespan of the five-axis rotary table. However, during machining operations, the lack of lubrication inside the five-axis rotary table causes the worm gear and worm shaft to overheat over time, accelerating their wear. Utility Model Content

[0003] The purpose of this invention is to provide a double-support five-axis precision rotary table to solve the problem mentioned in the background art where, during the machining process, the five-axis rotary table lacks a structure with added lubricating fluid, causing the worm gear and worm in the five-axis rotary table to experience increased temperature and aggravated wear over long-term operation.
