Magnetic steel installation tooling for electro-hydraulic servo valve of hydraulic industry

Abstract

The invention relates to a magnetic steel installation tooling for an electro-hydraulic servo valve of a hydraulic industry, comprising a pilot valve body (1), a nozzle body (2), an intermediate transition body (5), a magnetic seat (7), magnetic steel (8) and a plugging block (9), wherein the intermediate transition body (5) is installed on the pilot valve body (1), and the center line position of the pilot valve body (1) and the intermediate transition body (5) is provided with the nozzle body (2) and a jet pipe (6) in sequence from bottom to top; the nozzle body (2) is connected with the jet pipe (6) through screw threads, the outer side of the jet pipe (6) is provided with a duct (3), and a bushing (4) is sleeved outside the duct (3); the upper part of the intermediate transition body (5) is connected with the magnetic seat (7) through screws, and the magnetic seat (7) is in an L shape and is in bilateral symmetry; the magnetic steel (8) which is fixed through a bolt is stuck to the inner side surface of the sort side of the L shape; and the plugging block (9) is installed among the magnetic steel (8). The invention has the advantages of convenience for operation, reliable positioning and high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of assembling and debugging electro-hydraulic servo valves in the hydraulic industry, and in particular relates to a magnetic steel installation tool for electro-hydraulic servo valves in the hydraulic industry. Background technique [0002] At present, the manufacturing technology of the domestic electro-hydraulic servo valve industry is still at a relatively backward stage, especially the relatively high-end servo valves are difficult to meet the design requirements in assembly, including the installation of magnetic steel, which is difficult to achieve a symmetrical effect. The installation of steel has the following disadvantages: 1. The alignment of the magnetic steel cannot be guaranteed; 2. The magnetic steel itself is easily broken during the installation process, which affects performance; 3. The magnetic steel has strong magnetism, and the gap cannot be precisely controlled during installation; The...

[0002] At present, the manufacturing technology of the domestic electro-hydraulic servo valve industry is still at a relatively backward stage, especially the relatively high-end servo valves are difficult to meet the design requirements in assembly, including the installation of magnetic steel, which is difficult to achieve a symmetrical effect. The installation of steel has the following disadvantages: 1. The alignment of the magnetic steel cannot be guaranteed; 2. The magnetic steel itself is easily broken during the installation process, which affects performance; 3. The magnetic steel has strong magnetism, and the gap cannot be precisely controlled during installation; The above problems can be solved by using the plug, and the manufacturing cost can be greatly reduced
