Problems solved by technology

However, this kind of displacement digital display device cannot be used at all in other harsh environments, such as open air, mines, underwater; or in harmful media; or will be severely corroded and shorten the service life
If existing inductive synchros are used in machines and equipment that require large displacement, relatively low precision and harsh working environments, it will not be able to meet the requirements of economy, technology and working conditions.
Very ill suited to the needs of production technology facilities

Embodiment Construction

[0017] The implementation debugging process of the present invention is as follows: with reference to image 3 Reduce the displacement of the hoist gate or other machines to 0, at this time the travel switch of the main engine should act, and the standard voltage (25) should be adjusted to any positive value, generally adjusted to 8-10 volts. Adjust the multi-roll potentiometer (7) so that the digital display shows 0. Then connect the main engine with the conversion part (any kind of mechanical conversion or pulse conversion), the main engine runs, the conversion part and the multi-roll potentiometer also rotate accordingly, when the displacement reaches the maximum value, the travel switch acts, and carefully measure the gate Or the maximum height displacement of the machine, adjust the standard voltage regulator (25), so that the number displayed by the digital display meter is equal to the actual measured displacement number, and the measurement can be carried out by repeat...

Abstract

The invention relates to a voltage displacement digital display. The method can intuitively measure and display the displacement amount of the machine equipment, and when the displacement of 0 to 30 meters is measured, the display accuracy can reach+ / -0.001 meters; when the distance between 0 and 300 meters is measured, the display accuracy can reach +- 0.01 m. The digital display is suitable foropen-air, mine, underwater work hoist, hydraulic hoist and other machine equipment with bad working environment, large machine displacement amount and relatively low precision. The digital display hasthe advantages of simple structure, low cost and wide measurement range, and provides a condition for the automatic management of the electronic computer of the machine equipment.

Description

technical field [0001] The invention belongs to an electronic measuring instrument, which is a device for measuring the displacement of machinery and equipment. Background technique [0002] At present, in mechanical processing and numerical control machine tools, displacement digital display devices have been widely used. The existing digital display device is mainly composed of two parts: a detection device and a digital display meter. In automatic detection devices, digital display devices such as gratings, magnetic rulers, and inductive synchros have good stability and high measurement accuracy, so they have been fully used. Now take the linear induction synchronizer as an example: its structure is mainly composed of a fixed length and a slide rule. The slide ruler moves with the mechanical displacement part, and the fixed length is fixed on the machine tool body. Due to the relative movement of the fixed and sliding rulers, electric signals are generated and sent to ...
