Abstract

The invention discloses a hydrostatic rotary module, which has: a surface part, which has a bonding surface; an oil cavity part, which is arranged on the bonding surface, and the oil cavity part has at least one first oil chamber , at least one second oil chamber, at least one third oil chamber, at least one first oil passage, at least one second oil passage, at least one third oil passage and at least one fourth oil passage; the first oil passage communicates with the first oil chamber; the second oil passage communicates with the first oil passage and the second oil chamber; the third oil passage communicates with the third oil chamber and the second oil passage; the fourth oil passage The passage communicates with the second oil passage; an oil receiving seat is located on the side of the oil cavity that does not face the fitting surface, and the oil receiving seat has at least one oil inlet passage; the oil inlet passage is opposite to the fourth oil passage. an oil channel; and a mandrel passing through the oil bearing seat and the oil cavity and coupled to the table.

Description

technical field [0001] The invention relates to a hydrostatic rotary module, in particular to a hydrostatic rotary module capable of providing rigidity and precision. Background technique [0002] The hydrostatic rotary module is mainly used in super-heavy load machine tools or ultra-precision machine tools and industrial equipment or instruments. Therefore, the hydrostatic rotary module has the advantages of high precision and large load, and is widely valued by the machine tool industry. [0003] However, the hydrostatic rotary module integrates axial precision and radial precision to meet the requirements for precision. However, the more common method at present is to divide the axial accuracy and radial accuracy into two systems, so it will cost a relatively high cost to achieve high precision. Therefore, there is room for discussion on how to reduce costs, improve accuracy, or integrate axial accuracy and radial accuracy. Contents of the invention [0004] In order...
