AI Technical Summary
The eccentric sleeve structure in the CNC machine tool drive system is complex, resulting in high cost, inconvenient disassembly, and low maintenance and adjustment efficiency, which cannot meet the needs of high-efficiency production.
Design a simple eccentric sleeve that connects to the slide and reducer using fastening holes and threaded holes, and is fixed with bolts. Eccentric marks and positioning bosses are set on the eccentric sleeve body to enable convenient fine adjustment of the reducer's installation position.
It simplifies the production process, reduces production and maintenance costs, improves assembly efficiency and transmission smoothness, and facilitates maintenance and disassembly.
