Piston type walking component levelness measuring device and method

Abstract

The invention discloses a piston type walking component levelness measuring device and method. The method comprises the following steps that a launching device is placed on the plane parallel to a piston to be measured, a certain distance is formed between the launching device and the piston to be measured, and the launching device launches horizontal laser ray to the piston to be measured; a ruler synchronously moving with the piston to be measured records the emergent light offset according to changes of the irradiation position of the horizontal laser ray; a light sensing device on the piston to be measured converts the light offset into electric signals capable of being transmitted remotely, and the electric signals are transmitted to a control device; the control device receives the electric signals of the light sensing device, and the horizontal offset of the piston is calculated according to the light offset in the electric signals. The launching device launches laser ray to thepiston to be measured, and the light sensing device converts the light offset into remote transmission electric signal information into the control device, the control device calculates the horizontal offset information of the piston to be measured, and the levelness of the piston is measured.

Description

technical field [0001] The invention relates to level measurement, in particular to a measuring device and method for measuring the levelness of piston-type running parts by using horizontal laser rays. Background technique [0002] At this stage, there are many types of piston level measuring devices (especially gas tank type piston level measuring devices), generally there are connecting pipes to measure liquid pressure difference, multi-point laser range finder to measure distance, and indirect measurement of liquid depth in oil tank on piston, etc. Various types. [0003] Among them, the liquid pressure difference measured by the connecting pipe is small, and it is not easy to measure accurately; the multi-point laser measurement distance can measure the distance position of each point more accurately but the cost is high; the liquid depth measurement of the oil tank on the piston generally adopts an input liquid level gauge or Radar position measurement, piston tilt is...
