Abstract
The present invention relates to a flow control method for a high-accuracy and high-stiffness hydrostatic device, comprising: a main body and an auxiliary body; the upper surface of the main body forms a first flow channel, and a lug boss is formed on the first flow channel; the upper surface of the main body forms a second flow channel; the middle of the main body is concave down to form a pressure stabilizing cavity; the end of the first flow channel is provided with first throttling holes; the second flow channel is provided with a main oil hole; the first flow channel is provided with an oil distribution channel; the lug boss is provided with a second throttling hole; a bump matched with a bearing platform is formed on the bottom of the auxiliary body; a film sheet is arranged between the bump and the bearing platform; and the surface of the bump is provided with a groove. The present invention can complete flow control by a mechanical mode without any control module, and the oil film rigidity is high, which greatly reduces the use cost and improves the use reliability. The present invention has extremely high practicability. The present invention can be applied to relevant dev…
