Description

Novel oil cylinder with displacement sensor

Technical Field

The utility model relates to the technical field of oil cylinders, in particular to a novel oil cylinder with a displacement sensor.

Background

The hydraulic cylinder is a hydraulic actuator which converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has simple structure and reliable operation. When it is used to implement reciprocating motion, it can omit speed-reducing device, and has no transmission gap, and its motion is stable, so that it can be extensively used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is in direct proportion to the effective area of the piston and the pressure difference between the two sides of the effective area; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder cover, a piston and a piston rod, a sealing device, a buffering device and an exhaust device. The damping device and the exhaust device are determined according to specific application occasions, and other devices are necessary.

The common oil cylinder cannot detect and feed back or automatically control the extension length of the piston rod, namely the displacement of the piston rod of the hydraulic oil cylinder cannot be accurately controlled, so that the motion trail of the working part of the engineering machinery cannot be accurately controlled, when the motion of the working part of the engineering machinery is controlled, the motion trail needs to be observed and controlled by depending on the experience of an operator, the labor intensity of the operator is high, the control precision is difficult to guarantee, and the automatic and intelligent control of the engineering machinery and the coal mine machinery is difficult to realize.

Therefore, an oil cylinder with a displacement sensor is provided. The displacement sensor is arranged at the bottom of the cylinder body, and a steel wire of the displacement sensor is fixedly connected with the piston or the piston rod. When the cylinder body of the oil cylinder needs to be hinged, the bottom of the cylinder body needs to be connected with a bearing seat. But installation is difficult due to the obstruction of the displacement sensor. If install displacement sensor at the bearing frame tip, receive the articulated hole's of bearing frame hindrance again, the steel wire line can't pass. Therefore, the oil cylinder is inconvenient to install and use.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems in the background art, the utility model discloses a novel oil cylinder with a displacement sensor.

The utility model provides a novel oil cylinder with a displacement sensor, which comprises a cylinder body, a bearing seat and the displacement sensor, wherein the displacement sensor is arranged on the side part of the bearing seat;

a steel wire rope on the displacement sensor sequentially penetrates through the bearing seat, the bottom of the cylinder body and the inner hole of the piston; the part of the steel wire rope penetrating through the bearing seat and the bottom of the cylinder body is in an inclined bending shape.

The position of the displacement sensor is arranged, so that the installation of the bearing seat cannot be influenced, and the bearing seat cannot be blocked by a hinge hole of the bearing seat, so that the displacement sensor is more convenient to install and use.

Because the traditional steel wire rope bending part needs to use an arc-shaped hole to realize guiding, the processing difficulty of the arc-shaped hole is higher, the problem is further improved and solved, specifically, a through hole for inserting the steel wire rope bending part is a straight hole, and the diameter of the through hole is larger than that of the steel wire rope.

In order to explain the specific position structure of the insertion holes, in the scheme, the insertion holes are divided into two parts, one part is arranged on the bearing seat, and the rest part is arranged on the bottom of the cylinder body and penetrates through the cylinder bottom.

The bottom of the cylinder body is provided with a cylinder bottom which is detachably connected, and the rest part of the through hole is arranged at the cylinder bottom.

The problem is further improved and solved because the steel wire rope is difficult to guide into the inner hole of the piston in the through hole, and particularly, a guide pipe is arranged in the through hole and is connected with two ends of the through hole. The steel wire rope penetrates into the inner hole of the piston under the guiding action of the guide pipe.

In order to realize smooth insertion of the steel wire rope into the guide pipe, in the scheme, one end of the guide pipe, which is positioned inside the bearing seat, is of a horn mouth structure.

In order to facilitate installation of the guide pipe, in the scheme, one end, close to the cylinder body, of the cylinder bottom is connected with a fixing plate, and the guide pipe is arranged on the fixing plate.

In this scheme, the guide plate is installed to the one end that the fixed plate is close to the cylinder body, the deflector hole is the horn mouth structure, and its flaring end is directional the stand pipe for can insert the piston hole smoothly after wire rope passes the fixed plate hole.
