Abstract

The invention provides a valve sleeve boring fixture and belongs to the technical field of hydraulic mechanical manufacturing. The valve sleeve boring fixture specifically comprises a fixture body, alocating pin and lead screws. The fixture body is a cylindrical hollow eight-edge prism. The eight surfaces of the fixture body are all provided with through holes. The lead screws penetrate through the fixture body and are fixed to the fixture body through nuts. The lead screws are symmetrically arranged on the edges of the fixture body. The valve sleeve boring fixture provided by the invention can enable a valve sleeve and the fixture body to be coaxial and ensure the position correctness and high precision of machining holes. Moreover, a machined valve sleeve is complete in appearance and high in rate of finished products.

Description

technical field

[0001] The invention relates to the technical field of hydraulic machinery manufacturing, in particular to a valve sleeve boring fixture. Background technique

[0002] Hydraulic valves are components used in hydraulic transmission to control fluid pressure, flow and direction. Existing hydraulic valves require various processing during the production process, such as drilling multiple rows of holes on the valve sleeve. Because these holes have small diameters and high processing accuracy; and the valve sleeve is cylindrical, it is difficult for conventional fixtures to be effective. Fixed clamping can easily affect the machining accuracy, so a special valve sleeve boring fixture is needed.

[0003] Chinese Patent No. CN200710171643.2 discloses a processing fixture for the through hole of the valve sleeve in the electro-hydraulic servo valve. The valve sleeve is fixed in the drill body by positioning pins and positioning screws. The centering is not accurate,...
