Problems solved by technology

Built-in magnetic ruler, damage is not easy to repair
The magnetic scale is external, and the guide rod is easily deformed due to the long stroke
The potentiometer generally adopts the pull rope type. After the pull rope is long, it is easy to cause stretching and shaking, which affects the measurement stability.
[0003] At present, for large-scale long-stroke oil cylinder cylinder drive devices, due to the inconvenience of external installation of metering equipment, built-in methods are generally used
The built-in metering device such as the magnetic ruler is damaged, and it needs to be disassembled to repair the large long-stroke cylinder, which not only affects the use, but also takes a long time

Abstract

The invention provides a novel linear displacement measuring device. A built-in device for measuring the stroke of a long stroke oil cylinder and air cylinder is changed into an external measuring device. Linear motion is converted into rotary motion through a small reducer, a sprocket and a chain. Linear displacement stroke is output by using pulse counting of a rotary encoder. The cost and laborintensity are reduced, and the equipment availability is improved.

Description

technical field [0001] The invention relates to the technical field of measuring devices, and more specifically relates to a novel linear displacement measuring device. Background technique [0002] In order to control some moving equipment, in practical applications, some equipment needs to measure linear displacement, usually using analog signal measurement, such as magnetic scale, potentiometer, etc. For the measurement of linear displacement, there are two conventional methods: the first is to use a magnetic ruler to measure, and the second is to measure with a potentiometer. Both methods have some disadvantages. The magnetic ruler is built-in, and the damage is not easy to repair. The magnetic scale is external, and the guide rod is easily deformed due to the long stroke. The potentiometer generally adopts a drawstring type, and when the drawstring is long, it is easy to cause stretching and shaking, which affects the measurement stability. [0003] At present, for ...
