Abstract
The utility model relates to a depth tester for pull bruise marks on the surface of an object, which is suitable for testing the flaw depth on the outer diameter of a cylinder or the plane surface of an object. The utility model belongs to a testing instrument for flaw depth on the surface of an object, and is characterized in that a dial gauge or a dial indicator is installed on a supporting rack with a bracket, a supporting foot and a balance bar, and a knife-shaped testing head replaces the spherical measure head of the primary instrument. The dial gauge with a supporting rack is arranged near a wound on the surface of the tested object, the testing knife of the knife-shaped testing head is put in the wound, and then the depth value shown by the pointer of the dial gauge can be read out. The utility model solves the problem that people has no method for testing flaw depth on the surface of an object for many years, and the utility model has the advantages of simple structure, low cost and convenient use.
Description
The utility model body surface is pulled the detection that the bruise mark depth detecting instrument is applicable to the Cylinder external diameter or the object plane surface scar degree of depth, be particularly suited for the position such as axle journal, axle body of rolling stock wheel shaft, owing to draw, bump, fray, slide mark, or the detection of the injurious surface mark degree of depth that reason caused such as electric welding sparking, belong to the detecting instrument of the body surface scar degree of depth.
For the pulling of the surfaces, position such as axle journal, axle body and dust guard seat of the automobile-used wheel shaft of railway passenger and freight, the bruise mark degree of depth, there is not a kind of detection means, can only detect by an unaided eye in the past and judge whether it surpasses the limit gauge of Ministry of Railways's regulation, therefore very inaccurate, often there is the scar degree of depth to return the repair in shop reason, causes waste less than the wheel shaft of limitting.
The purpose of this utility model will design a kind of easy to use simple and direct, can accurately measure the detector of scar on Cylinder external diameter or the object plane surface, to overcome the various shortcoming that visual inspection is brought.
The purpose of this utility model can realize in the following manner.
Select the dial gauge of common metering usefulness for use, the basic structures such as gauge outfit, clamping bar, sounding rod, gauge head and initial adjustment knob that keep dial gauge are constant, change the spherical gauge head that is connected on the sounding rod 3 into cutter shape gauge head 4, and the bearing support 2 that is made of support 5, leg 6 and haltere 7 is set, dial gauge 1 is connected on the bearing support 2.Bearing support is vertically fallen within on the outer diametric plane of Cylinder (or on object plane surface), the cutter shape gauge head of dial gauge can touch directly that this body surface is pulled, cut etc. is greater than narrow, the dark scar bottom of 0.3mm, and then the degree of depth of this scar can show by the scale on the dial gauge dial plate.The dial gauge that is installed on the bearing support also can be by clock gauge or by dial gauge and combined next the substituting of sensor.
This depth detecting instrument can accurately measure the body surface scar degree of depth, especially in the rolling stock maintenance, the position injurious surface mark degree of depth such as axle journal, axle body and dust guard seat to axletree can accurately be measured, and have avoided scar the reprocessing of axletree of not transfiniting, and have saved human and material resources, financial resources; In addition, with this detector axle journal, axle body etc. is monitored the generation that can reduce combustion axle, hot box or cut an accident, favourable traffic safety; This detector is simple in structure, and is cheap, easy to use.
The utility model is described in further detail below in conjunction with drawings and Examples.
