Measuring tool for measuring the width of inner ring groove on inclined plane

Abstract

The invention relates to a measuring tool for measuring the width of an inclined plane inner ring groove. The measuring tool includes an upper gauge block and a lower gauge block. The key points are that a measuring bar and a slide bar which are fixedly connected are arranged on the lower gauge block; a measuring plane and a measuring rod through hole and a slide bar through hole which correspond to the measuring rod and the slide bar on the lower gauge block are arranged on the upper gauge block, and the measuring rod and the slide bar can slide up and down in the measuring rod through hole and the slide bar through hole respectively; two step type detection planes are arranged on the measuring rod; measuring heads with inclined planes and a spring are arranged on the upper gauge block and the lower gauge block; and the upper gauge block and the lower gauge block are connected through a limiting plate which is connected with the lower gauge block through a screw and is connected with the upper gauge block in a sliding manner. The measuring tool provided by the invention is simple in structure, easy to manufacture, and convenient and flexible to operate, the contact of the measuring heads and a measured part is stable, repeatability and consistency are good, part machining and detection efficiency is improved, and manufacturing expenses of the part are effectively reduced; and for parts to be measured of different specifications, detection of the groove width of the parts can be completed only by replacement with corresponding measuring heads and measuring rods, and the measuring tool is strong in practicability and good in economical efficiency.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a measuring instrument for measuring the width of an inner ring groove on an inclined plane. Background technique [0002] For many shaft parts, there is an annular groove in the inner hole, and both sides of the groove are sloped, and it is usually required to measure the width of the groove at a specified diameter value. Commonly used groove width gauges are of straight-edge type, which cannot measure the groove width with hypotenuse; if three-coordinate measurement is used, the data cannot be directly obtained, and conversion is required. The most important thing is that it cannot be measured at the production site. Worker's operation brings inconvenience; This method is time-consuming and laborious, very inconvenient. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings in the above-mentioned measurement, and provide a measuring to...

Commonly used groove width gauges are of straight-edge type, which cannot measure the groove width with hypotenuse; if three-coordinate measurement is used, the data cannot be directly obtained, and conversion is required. The most important thing is that it cannot be measured at the production site. It is inconvenient for workers to operate; this method is time-consuming and labor-intensive, which is very inconvenient
