Abstract
The utility model relates to a hobbing and milling combined machine tool for a bearing bush cover, belonging to a special combined machine tool. The combined machine tool comprises an electronic control cabinet, a hydraulic unit, a special working table, a cooling system, a clamp body, a hydraulic clamp, a cutter, a cutter bar support, a special milling head box body, a centralized lubrication device, a numerical controlled feeding box and a chip removal system. The machine tool is designed by the combination of mechanical and hydraulic principles as well as the numerical control technology and is specially used for cutting the bearing bush cover. The cutter bar support is divided into an upper half body and a lower half body by employing a huff structure, so that the cutter bar support is convenient to disassemble, has good stability and avoids the cutting vibration. When the cutting is over, an electrical system controls a hydraulic cylinder to stop for 0.2-0.3s, and then the cutter is taken back, so as to avoid the cutter carrying when the cutter is taken back. The combined machine tool is high in machining precision, stable in mechanical performance and safe and convenient in operation and improves the production efficiency.
Description
