Built-in magnetostrictive displacement pressurizer

Abstract

The invention discloses a built-in magnetostrictive displacement pressurizer. The built-in magnetostrictive displacement pressurizer comprises a body structure, wherein the body structure consists ofa body and a front cylinder, the body is provided with a first sliding cavity, a second sliding cavity in the front cylinder communicates with the first sliding cavity, a plug is arranged at the rearend of the front cylinder, an oil outlet communicating with the second sliding cavity is formed in the plug, and a pressure gauge or an oil cylinder is connected through an oil outlet; a piston rod comprises a piston part and a rod body, wherein the piston part is arranged in the first sliding cavity, and the rod body stretches into the second sliding cavity; the built-in magnetostrictive displacement sensor comprises a magnetic ring and a measuring rod, wherein the magnetic ring is arranged at the front end of the piston part, the measuring rod penetrates through the magnetic ring and extendsinto a sliding groove arranged in the piston rod, the front end of the measuring rod is hermetically fixed with the body, and an interval is formed between the measuring rod and the inner wall of themagnetic ring and the inner wall of the sliding groove; and the front end and the rear end of the body are respectively provided with a first oil port and a second oil port, the first oil port and the second oil port communicate with the first sliding cavity, a third oil port is further formed in the rear end of the body, and the front end of the front cylinder is provided with a fourth oil portwhich corresponds to the third oil port and communicates with the second sliding cavity.

Description

Technical field: [0001] The invention relates to the technical field of supercharger products, in particular to a built-in magnetostrictive displacement supercharger. Background technique: [0002] The oil cylinder is an oil pressure actuator that converts oil pressure energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. [0003] During the use of the oil cylinder, sometimes it needs to be boosted to meet the processing requirements. Then it is necessary to install a supercharger outside the oil cylinder to pressurize the oil cylinder. However, the supercharger in the prior art needs to install a displacement sensor externally to measure the stroke displacement, resulting in a hu...

Then it is necessary to install a supercharger outside the oil cylinder to pressurize the oil cylinder. However, the supercharger in the prior art needs to install a displacement sensor externally to measure the stroke displacement, resulting in a huge and complicated structure of the supercharger, and Measurement results are not stable
