Spiral height adjusting mechanism for hydraulic machine and machining process thereof

Abstract

The invention relates to a spiral height adjusting mechanism for a hydraulic machine. The spiral height adjusting mechanism comprises a first limiting block arranged on a fixed plate and a second limiting block installed at the bottom end of a floating plate. The first limiting block is in an annular shape in whole, a cylindrical fixed seat is arranged on the fixed plate, the fixed seat is sleevedwith the first limiting block, the first limiting block consists of an upper limiting block and a lower limiting block, the bottom surface of the upper limiting block is of a spiral inclined surfacestructure, the top end of the lower limiting block is of a spiral inclined surface structure mutually complemented with the bottom surface of the upper limiting block, and the first limiting block isdriven by a rotating mechanism to realize change of the height of the whole first limiting block. The second limiting block is driven by a horizontal cylinder to move to the position above the first limiting block or move out of the position above the first limiting block. The invention further relates to a machining method of the height adjusting mechanism. The spiral height adjusting mechanism has the advantages that the annular design is adopted for the first limiting block, so that the lower end face of the floating plate can be integrally supported, and the phenomenon of inclination of the floating plate is effectively avoided.

Description

technical field [0001] The invention relates to a screw-type height adjustment mechanism for a hydraulic machine, and also relates to the processing technology of the height adjustment mechanism. Background technique [0002] Powder metallurgy is a process technology for producing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, after forming with pressure or without pressure, and then sintering to manufacture metal materials, composites and various types of products. Powder metallurgy technology has a series of advantages such as significant energy saving, material saving, excellent performance, high product precision and good stability, and is very suitable for mass production. At present, powder metallurgy technology has been widely used in transportation, machinery, electronics, aerospace, weapons, biology, new energy, information and nuclear industries, and has become one of the most dynamic branches of new material scienc...
