Description

Spiral disc type indicator verification instrument

Technical Field

The utility model relates to detection equipment, in particular to a spiral disc type indicator verification instrument.

Background

The measuring instrument which converts the linear displacement of the measuring rod into the angular displacement of the pointer on the circular dial by using a mechanical transmission system and reads the pointer by the dial is called an indicator, and is divided into a mechanical indicator and an electronic digital indicator, and the indicator with the measuring range exceeding 10 mm is commonly called a large-stroke indicator.

Currently, manual and semi-automatic indicator verification instruments published in the market need to manually set detection points and return stroke measurement in the verification process, errors are easy to occur, and serious errors are caused to measurement results; the better measuring result can not be ensured while the workload is increased, and the method is time-consuming, labor-consuming and low in efficiency.

Disclosure of Invention

In order to solve the technical problems, the technical scheme provided by the utility model is as follows:

the spiral disc type indicator verification instrument comprises a verification instrument host, a detection disc and a to-be-detected meter; a rotating shaft is arranged at the geometric center of the verification instrument host; the measuring surface of the detecting disc is provided with an Archimedes spiral, and the strokes of the detecting disc are various; the rotating shaft is fixedly connected with the detection disc; the periphery of the measuring surface of the detecting disc is contacted with the measuring head of the meter to be detected.

The measuring surface of the detecting disc is arranged into an Archimedes spiral, the limit of the detecting point is realized mainly by utilizing the principle that the Archimedes spiral is equidistant, the selection of the detecting point is not needed to be carried out manually, the error in the detecting process is reduced, and the accuracy of the verification instrument is improved.

Preferably, the stroke of the detecting disk is any one of 3mm, 10 mm and 50 mm; the travel of the test disc is preferably of the above three types, mainly because the use of test meters of this type is more common in practice.

As a further preferable mode of the utility model, the to-be-detected meter is any one of a dial indicator, a dial indicator and a lever meter; the above three types of indicators are preferred mainly because these three types of detection indicators are more widely used in practical operation.

As still further preferable, a base is arranged below the verification instrument host; by arranging the base below the verification instrument host, corrosion of some corrosive liquid in the actual environment can be effectively avoided in actual operation, and the service life of verification equipment is prolonged.

Compared with the prior art, the utility model has the beneficial effects that: by arranging the Archimedes spiral detection disc, the problem that detection points are required to be set manually by manual and semi-automatic verification instruments in the market is solved according to the principle that Archimedes spiral lines are equidistant, errors in actual measurement are reduced, the accuracy of detection results is improved, and the detection efficiency is improved; meanwhile, compared with a full-automatic verification instrument, the utility model has simpler structure and more convenient operation on the aspect of solving the same problems.
