Abstract
The utility model relates to a generatric straightness detecting gauge including a micrometer dial and a measuring gauge block. The generatric straightness detecting gauge is characterized in that the bottom face of the measuring gauge block is an arc face provided with a rectangular orthographic projection. Measuring through holes with the same inscribed circle diameter and having axes that are perpendicular to the upper surface are arranged in the central line of the upper surface of the measuring gauge block in a longitudinal direction. Side faces of the measuring block are provided with fastening screw holes corresponding to the measuring through holes and fastening screws are installed in the screw holes. A measuring rod of the micrometer dial is connected with a lengthening bar. An end part of the lengthening bar is provided with a steel ball measuring probe. The generatric straightness detecting gauge has advantages that the generatric straightness detecting gauge is convenient, quick, direct and accurate and can meet requirements for detecting generatrix of inscribed circle annule.
Description
Technical field
The utility model relates to a kind of plain line Linearity surveying gauge, is specifically related to a kind of detection gauge for detection of adapter inner saddle face two endless belt elements line linearitys, belongs to the test measuring device field.
Background technology
In order further to contain Hot Box Troubles on Railway Freight Cars, standard and reinforcement freight train loader saddle workmanship, improve detection means, for guaranteeing the fit quality of adapter saddle face and bearing outer ring, saddle face two endless belt diameters, right alignment and plain line linearity are had very strict requirement.
Present detection mode accuracy of detection is not high, and data error is large, affects product quality.
Summary of the invention
The purpose of this utility model is the requirement for bogie adapter inner saddle face two endless belt element line Linearity surveyings, provide a kind of plain line Linearity surveying gauge that coordinates steel ball probe measurement inner circle element line linearity with clock gauge, to solve the problem that present accuracy of detection is not high, data error is large.
The technical scheme that its technical matters that solves the utility model adopts is as follows:
The utility model comprises micrometer dial, measures gauge block, it is characterized in that: the bottom surface of measuring gauge block is the arc surface that orthogonal projection is rectangle, the compartment of terrain has the identical measurement through hole of the vertical interior circular diameter of axis and upper surface on the center line of the length direction of measuring the gauge block upper surface, have accordingly with each measurement through hole in the side of measuring gauge block and hold out against screw hole, be equipped with in screw hole and hold out against screw; Be connected to extension rod on the sounding rod of micrometer dial, the end of extension rod is provided with the steel ball measuring sonde.
The utility model has the advantages that: convenient and swift, accurately directly perceived, ring belt element line Linearity surveying requirement in satisfying.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model.
Embodiment
With reference to accompanying drawing, the utility model comprises micrometer dial 2, measures gauge block 1, the bottom surface of measuring gauge block 1 is the arc surface that orthogonal projection is rectangle, the compartment of terrain has the identical measurement through hole 3 of the vertical interior circular diameter of four axis and upper surface on the center line of the length direction of measuring gauge block 1 upper surface, have accordingly with each measurement through hole in the side of measuring gauge block 1 and hold out against screw hole, be equipped with in screw hole and hold out against screw 6; Be connected to extension rod 4 on the sounding rod of micrometer dial 2, the end of extension rod 4 is provided with steel ball measuring sonde 5.
During measurement, four its sounding rods of micrometer dial with steel ball measuring sonde 5 are inserted respectively measuring in through hole 3 of measurement gauge block 1.Before measuring, the reading of each micrometer dial is set up to zero graduation, tighten and hold out against screw 6, then the bottom surface that will measure gauge block 1 is placed on measuring piece 7 measurement faces, steel ball measuring sonde 5 all drops on the saddle face, press down micrometer dial, the plain line linearity of difference judgement of the minimum and maximum value of being surveyed with four micrometer dials.
