Description

Measuring device for the axial length of the inner hole of the pulley

technical field

The invention relates to a length dimension measuring instrument of mechanical parts, in particular to a measuring device for the axial length of the inner hole of a pulley.

Background technique

At present, the quality of automobile engines is improving rapidly, whether it is life, noise, energy saving, or stability. Improving the dimensional accuracy and shape accuracy of the engine pulley is also an important part of improving engine quality. The traditional measurement of the length of the pulley adopts conventional measurement methods, and manual measurement is performed by tools such as vernier calipers.

This measurement method has low efficiency. It is controlled by human hands during measurement, which affects the accuracy of measurement. There is also measurement parallax when reading, which brings great errors to the measurement results. These traditional inspection methods are obviously It cannot meet the technical development trend of the modern machinery industry. After extensive searching, no ideal technical solution has been found.

Contents of the invention

The purpose of the present invention is to solve the shortcomings of low efficiency and inaccurate measurement data when measuring the depth of the center hole of the pulley at the present stage, and propose a measuring device for the axial length of the inner hole of the pulley.

In order to achieve the above object, the present invention adopts the following technical solutions:

The measuring device for the axial length of the inner hole of the pulley is characterized in that it comprises: a base, a column is connected to the base, a mandrel is connected to the post, a micrometer is connected to the mandrel, and a standard block is movably connected to the mandrel.

On the basis of above-mentioned technical scheme, can have following further technical scheme:

A connection plate is arranged on one side of the mandrel, and the connection plate is connected to the column, and a micrometer is also connected to the connection plate.

When zeroing, the mandrel is socketed with a standard block, and the probe of the micrometer is in contact with the end face of the standard block; when measuring, the mandrel is socketed with a pulley, and the probe of the micrometer is in contact with the end face of the pulley.

The base is connected to the tester, and the tester is connected to the micrometer.

The detector has a data storage function, and the measured data can be read out and stored by the display screen of the detector.

The connecting plate on one side of the mandrel is connected by bolts at the top of the column, and the connecting plate on the other side of the mandrel is provided with a through hole, which passes through the through hole; the bolts are locked to match the micrometer, and the measuring head of the micrometer is upward.

One side is connected to the fixed shaft by bolts, and the standard block is socketed on the fixed shaft.

The invention has the advantages of simple structure, convenient use, high measurement speed and high precision, improved work efficiency, effective technical data for the quality control of the pulley, and an effective measuring device for the processing of the pulley.
