Description
Technical Field
The utility model relates to the technical field of vibration prevention, in particular to a liquid and air bag vibration prevention supporting device.

In the field of mechanical manufacturing, metal cutting of thin-walled parts has been difficult. Because the wall of the part is thin and the rigidity is insufficient, the part is easy to vibrate like a spring piece when being extruded by a cutting tool, and the vibration is caused, so that the quality of the cutting surface is reduced, and the workpiece is deformed. In general processing, a hard support method is generally adopted to increase the rigidity of a workpiece, a hard core shaft matched with a part is tightly inserted into a tubular workpiece, and the workpiece is ensured to resist the shape opening and the caused vibration during processing. This method has the following disadvantages: 1. the corresponding hard core shaft is required to be equipped according to each part, and the cost is high. 2. Because of the hard material, the tight fitting with the piece is impossible, and because of the poor shock absorbing capacity of the hard material, the shock absorbing support effect is limited. 3. For parts with complex shapes, hard mandrels are difficult to manufacture or cannot be installed after manufacture.
