Abstract

A kind of verticality measurement device, it is the verticality that both direction is measured by 4 points of non-contact range measurements.The device is easy to operate automatic, the squareness measurement being suitable in various engineering practical problem.

Description

A kind of verticality measurement device

Technical field:

The utility model relates to a kind of angle measurement unit, specifically a kind of verticality measurement device.

Background technique:

In fields such as machining, geology petroleum works, architectural engineerings, it is often necessary to the measurement about verticality.It is existing Measuring device have clearance gauge, inclinator, level meter etc., most methods there are measurement accuracy it is not high, inconvenient the problems such as.

Utility model content:

The purpose of this utility model is that providing a kind of verticality measurement device in view of the deficiencies of the prior art.The device Squareness measurement is carried out using 4 points of non-contact distances, measurement accuracy is high, and high degree of automation is easy to operate.

The technical solution of the utility model includes:

Four current vortex heads are fixed on axis to be measured with fixes sleeve, keep certain distance with plane to be measured；By electric whirlpool It flows head and exports four distance signals, be transmitted to single-chip microcontroller, single-chip microcontroller handles after data that the results are shown on LCD.

The beneficial effects of the utility model are: compared with the prior art, the utility model is a kind of non-contact based on 4 points Ranging carries out the self-operated measuring unit of verticality, and measurement accuracy is high, and high degree of automation is easy to operate.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the utility model.

Marked in the figure: 1 axis to be measured, 2 planes to be measured, 3 fixes sleeves, 4 current vortex heads, 5 single-chip microcontrollers, 6LCD.

Specific embodiment:

As shown in Figure 1, a kind of verticality measurement device.Including 1 axis to be measured, 2 planes to be measured, 3 fixes sleeves, 4 current vortexs Head, 5 single-chip microcontrollers, 6LCD.

Four current vortex heads 4 are fixed on axis 1 to be measured, keep a spacing with plane 2 to be measured by the fixes sleeve 3 From；Four distance signals d1, d2, d3, d4 are exported by current vortex head 4, are transmitted to single-chip microcontroller 5, single-chip microcontroller 5 is handled result after data It is shown on LCD6.

The verticality measurement device working principle is: by current vortex non-contact distance-measurement d1, d2, d3, d4, opposite two The ratio between point place range difference (d1-d3), (d2-d4) and their spacing x, y two-by-two can obtain the verticality of the direction.

When current vortex range accuracy is 0.1 μm, and spacing is 100mm, angle-measurement accuracy can reach 0.0001 degree.

Further, four current vortex heads 4 can be replaced laser displacement sensor.
