Piston cylinder and installation method thereof

Abstract

The invention provides a piston cylinder and an installation method thereof. The piston cylinder comprises a cylinder barrel (40), a piston rod (60) and an installation base assembly (30). The cylinder barrel (40) is provided with an end cover (43), the end cover (43) is provided with a first inner hole (431) arranged along the axial direction of the end cover (43), the piston rod (60) is provided with a second inner hole (61) which is coaxial with the first inner hole (431), the installation base assembly (30) is fixed in the second inner hole (61), the installation base assembly (30) is provided with a third inner hole, the third inner hole and the first inner hole (431) are arranged coaxially, the third inner hole penetrates through a sensor (70), the third inner hole comprises a first inner hole section (3112), and the first inner hole section (3112) adapts to a sensor head (71) of the sensor (70) so as to clamp the sensor head (71) and achieve radial positioning. The piston cylinder facilitates installation of the sensor.

Description

technical field [0001] The invention relates to a sensor installation structure, in particular to a piston cylinder and an installation method thereof. Background technique [0002] As an actuator, the hydraulic cylinder is mainly used to drive the load for reciprocating linear motion. In order to meet the working requirements of different equipment, to be able to clearly grasp the operation of the equipment and know the specific position of the equipment mechanism, a displacement sensor needs to be installed inside the hydraulic cylinder, and the specific position of the equipment mechanism to be known through the displacement sensor. According to the specific position, To adjust the mechanism to achieve the purpose of controlling the operation of the equipment mechanism, and at the same time to meet the reliability and simplicity of processing and installation. [0003] Such as figure 1 Shown is an existing hydraulic cylinder, including a cylinder 40' with an oil port 41...

AI Technical Summary

Problems solved by technology

[0005] Because in the prior art, the installation hole in the positioning ring 311' and the sensor 70' are in a movable fit, the installation hole has no positioning function, and the mass of the piston 50', the piston rod 60' and the mounting seat assembly 30' is relatively large, and at the same time The sensing probe 72' of the sensor 70' is long and has a certain degree of winding, and there is an invisible state inside the cylinder 40', so when the sensor 70' is installed, the alignment between the sensor 70' and the above-mentioned components is relatively high. Poor, it is not easy to accurately pass the sensor 70' in the piston 50', the piston rod 60' and the mounting seat assembly 30', the workmanship is poor, and it will also damage the sensor 70' and its output harness 73' and other accessories
