The machining position for feeding the workpiece to be machined to the machine tool and the automatic or semi-automatic mechanical device for removing the processed workpiece from the machining position, also known as the workpiece automatic loading and unloading device. Most of the loading and unloading mechanism of the machine loading and unloading device is relatively simple, or the loading mechanism has the function of cutting off, so the loading and unloading device of the machine tool is also often referred to as the feeding device. The machine loading and unloading device is an integral part of the automatic machine tool. After the semi-automatic machine is equipped with the loading and unloading device, the machining cycle can be continuously and automatically performed, becoming an automatic machine tool. The machine tool loading and unloading device is used for semi-automatic machine tools with high efficiency, short maneuvering time and frequent loading and unloading of workpieces, which can significantly improve production efficiency and reduce manual labor. The machine tool loading and unloading device is also an indispensable auxiliary device for the automatic production line.
1. High rigidity and long-term precision retention:
1.1, the main large parts of the machine: base, workbench, column, beam, slide, ram are made of high-quality resin sand, high-strength high-quality cast iron, with a complete heat treatment process to eliminate residual stress, and arrange enough reinforcement The plate ensures sufficient strength, rigidity and high stability of the machine.
1.2, XY axis uses heavy-duty roller guide rail, strong rigidity and good dynamic precision.
1.3. Three-axis transmission adopts Taiwan brand large-diameter grinding double nut ball screw, which has compact structure, stable movement and high precision. The screw support uses precision screw support bearings, and the two ends are pre-stretched to eliminate the precision loss caused by thermal elongation. .
1.4. The beam adopts a stepped structure. The cross section of the beam is large, the span of the guide rail is large, the distance from the center of the main shaft to the surface of the guide rail is short, the turning torque is small, and the structural rigidity is good.
1.5. The high-rigid Taiwan brand gantry-specific spindle, which is lubricated with grease, can make the spindle bearing have constant and reliable lubrication, which is economical and environmentally friendly and achieves long-term maintenance-free.
2, high precision, high dynamic response characteristics:
2.1. The spindle adopts high-precision angular contact ball bearing to achieve high rigidity and high spindle rotation accuracy.
2.2, XY axis roller guide, high precision and large load. The friction is low, the low-speed crawling phenomenon of the machine tool is reduced, the positioning accuracy is good, and high dynamic response characteristics are obtained at the same time.
2.3, Z-axis adopts double hydraulic balance cylinder structure, simple structure and convenient maintenance.
3, high efficiency: spindle speed can reach 5000rpm, three-axis fast moving up to 12/15/10m/min.
4. Large processing range: Compared with the same specification machine tool, the 3.2m door width of the machine tool ensures a wider processing range.
