Embodiment Construction

[0019] A built-in displacement sensor type oil cylinder of the present invention comprises a cylinder barrel 9, a guide sleeve 3, a piston assembly, a vernier magnetic ring 8, a conduit 5 and a displacement sensor 10; the piston assembly includes a piston and a piston rod, and the piston rod consists of a piston rod head 2, The piston rod body 4 and the piston rod tail 7 are welded, and the piston rod adopts a welded structure, which avoids the processing of slender holes on the piston rod, thus simplifying the processing process and ensuring the feasibility of processing; the cylinder barrel 9 and the guide sleeve 3 It is coaxial and fixed; the piston assembly passes through the cavity of the guide sleeve 3 and the cylinder 9; the piston assembly is provided with a vernier magnetic ring 8, which is fixed at the end of the piston rod tail 8; the inside of the piston rod head 2 is designed with a guide tube Guide hole, the diameter of the guide hole of the guide tube is slightly...

Abstract

The invention relates to an oil cylinder for a built-in displacement sensor. The displacement sensor is arranged in a cavity with a piston rod, and an induction rod on the displacement sensor penetrates the cavity with the piston rod and a cavity with a piston rod; the partial piston rod body is located in a tube cavity; the outer diameter of the induction rod is smaller than the inner diameter ofthe tube cavity, so that hydraulic oil can enter the tube cavity through a cavity clearance between the induction rod and a tube; a cylinder barrel and a guide sleeve are each provided with an oil hole, and the hydraulic oil enters the cavity through the oil hole in the cylinder barrel or the oil hole in the guide sleeve; a piston component is pushed by the hydraulic oil in the cavity to move axially, and cursor magnetic rings are driven by the piston component to move; and the moving signals of the cursor magnetic rings are transmitted to the displacement sensor so that the moving distance of the piston component is obtained. The oil cylinder is high in safety, and the processing of the piston rod is simple; the tube can be deformed freely, and the disadvantages during installation of anexisting sensor are overcome.

Description

technical field [0001] The invention relates to the technical field of oil cylinders, in particular to a built-in displacement sensor type oil cylinder. Background technique [0002] At present, the installation of the displacement sensor on the oil cylinder generally adopts the exposed type, that is, the displacement sensor is installed on the outside of the oil cylinder as a whole, or the center is built-in, that is, the sensor is installed on the bottom of the cylinder, and the sensing rod extends into the inside of the oil cylinder and moves inside the piston rod. [0003] But above-mentioned two kinds of installation methods all have certain defectives. [0004] For exposed installation. First of all, this installation method lacks protection devices, and it is easy to be damaged by collisions with other objects; thirdly, the exposed installation method causes the installation volume of the oil cylinder to become larger, and the installation in a small space is limited...
