Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0029] The specific implementation is as figure 1As shown, four tubular pillars, trapezoidal isolation plate and bottom hydraulic support form a highly stable trapezoidal boss structure. The hydraulic oil with high shear viscosity is filled between the piston and the cylinder of the tubular pillar. When the piston rod vibrates, the gap between it and the cylinder wall will change, and the viscous hydraulic oil will be pressed out and sucked in sometimes. will cause squeeze film damping. Each support roller is embedded in the concave opening at the other end of the tubular pillar, and the junction is formed with a 0.10mm thick polytetrafluoroethylene film to form a sliding pair with a low friction coefficient and coated with grease. When cutting, there is relative rolling between the workpiece and the support roller, and the micro-slip between...

The invention discloses a workpiece supporting system for an extraheavy type machine tool. The system comprises a tool body, wherein a bottom hydraulic support is arranged on the right side above the tool body; a piston support is arranged on the left side above the tool body; the bottom hydraulic support and the piston support are provided with a rolling support of a damper respectively; a tubular supporting post is fixedly arranged on the rolling support of the damper; a support roller is arranged at the top end of the tubular supporting post; a workpiece is arranged above the support roller; a trapezoid isolation plate is arranged between the workpiece and the tool body; a driving device is arranged below the trapezoid isolation plate; and a driving shaft is connected on the driving device and passes through a hole formed in the middle of the trapezoid isolation plate to be contacted with the workpiece. In the system, the damping of a mechanism is increased by a damping vibration absorber principle, an extraheavy type workpiece can be supported to be smoothly rolled on the system, and the rigidity and the vibration resistance of the whole machining process system can be enhanced. The system is mainly suitable for the fields of machining and manufacturing of various large-scale machines such as a heavy-type machine, a wind driven generator, a nuclear energy generator, a ship manufacturing industry, a power equipment manufacturing industry and the like.
Description
technical field [0001] The patent of the invention relates to the technical field of mechanical processing. As an important accessory of a super-heavy machine tool, it specifically refers to a workpiece support system for a super-heavy machine tool that realizes vibration attenuation. It is mainly applicable to heavy machinery, wind power generators, nuclear power generators, The processing and manufacturing fields of various large-scale mechanical rotors such as shipbuilding and power equipment manufacturing. Background technique [0002] The current ultra-heavy-duty machine tool (with a machining diameter of more than 5 meters, a length of more than 20 meters, a load capacity of more than 500 tons, and multiple compound processing functions such as turning, drilling, and boring) during the processing process, the workpiece is mainly composed of the spindle box chuck and the top. It is clamped with the two ends of the top end of the tailstock, and there is also a special ce...
