Problems solved by technology

[0002] When the hydraulic cylinder is working, in order to meet the needs of the production process and automatic control, the stroke must be monitored in real time, which is generally realized by a displacement sensor and displayed on the operation panel of the equipment. However, in the actual production process, the operator often needs to be able to Visually observe the stroke of the hydraulic cylinder. At present, in the production process, the stroke of the hydraulic cylinder can be accurately detected, and there is no good solution to visually display the stroke of the hydraulic cylinder for the operator to observe.

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings. Such as Figure 1-2 As shown, the guide rod 3 is fixed on the hydraulic cylinder piston 2, the pull-rope displacement sensor 4 is connected to the guide rod 3, one end of the steel wire 6 is connected to the guide rod 3 through the guide frame 5, and one end is connected to the pointer 9, and the pointer 9 Connected with the spring reel 10, the guide frame 5, the scale 7, the guide groove 8 and the spring reel 10 are fixed on the cylinder block 1 of the hydraulic cylinder. The hydraulic cylinder stroke display device of the present invention can realize two modes of electric detection and mechanical detection. When the hydraulic cylinder piston 2 moves, it drives the guide rod 3 to move, and the guide rod 3 drives the rope-type displacement sensor 4 and the steel wire 6 to move. The rope-type displacement sensor 4 outputs an electrical signal, and the stroke of the hydr...

Abstract

The invention discloses a hydraulic cylinder stroke display device which comprises a pull rope type displacement sensor and a scale plate pointer mechanical portion. The displacement of a hydraulic cylinder piston is converted into an electrical signal through the pull rope type displacement sensor, and a hydraulic cylinder stroke is displayed on an operating panel in real time. The scale plate pointer mechanical mechanism consists of a guide rod, a guide frame, a steel wire, a scale plate, a guide groove, a pointer, a spring winding drum and the like, wherein one end of the steel wire is connected with the hydraulic cylinder piston through the guide rod and the guide frame, the other end of the steel wire is connected with the pointer, the pointer is connected with the spring winding drum, the spring winding drum is taken up when the hydraulic cylinder piston moves and accordingly drives the pointer to move on the scale plate along the guide groove, and the stroke position of the hydraulic cylinder piston is displayed in real time. The hydraulic cylinder stroke display device can accurately detect the hydraulic cylinder stroke and display the hydraulic cylinder stroke outside a hydraulic cylinder, facilitates observation of an operator and is accurate, reliable, intuitive and convenient to use, production efficiency can be improved, the safety operability of the device is greatly improved, and the detection accuracy of the device is ensured.

Description

technical field [0001] The invention relates to a hydraulic cylinder stroke display device, which belongs to the technical field of mechanical equipment. Background technique [0002] When the hydraulic cylinder is working, in order to meet the needs of the production process and automatic control, the stroke must be monitored in real time, which is generally realized by a displacement sensor and displayed on the operation panel of the equipment. However, in the actual production process, the operator often needs to be able to Visually observe the stroke of the hydraulic cylinder. At present, in the production process, there is no good solution to accurately detect the stroke of the hydraulic cylinder and display the stroke of the hydraulic cylinder intuitively for the operator to observe. Contents of the invention [0003] In order to solve the above problems in the prior art, the present invention designs a hydraulic cylinder stroke display device that can accurately det...
