embodiment:

embodiment 1 :

the expanding wheel device that steel ball surface defect detects, its composition comprises: back up pad 1 , described back up pad has plane, in described plane respectively with expansion element apparatus 2 , supporting member device 9 , drive unit 14 , detection probe 5 connect, between described expansion element apparatus and described supporting member device, tested steel ball is installed 4 , described tested steel ball and described drive unit pass through driving wheel 7 laminating, is provided with described detection probe above described tested steel ball side.

embodiment 2 :

according to embodiment 1 the expanding wheel device that described steel ball surface defect detects, passes through multidiameter inside described expansion element apparatus one end 13 be separately installed with left expanding wheel 3 , right expanding wheel 12 , described left expanding wheel and described right expanding wheel have the conical surface respectively, and the described conical surface and described tested steel ball are fitted, and described expansion element apparatus other end inside bottom is provided with back-moving spring 10 , spring fixed bar is installed above described back-moving spring 11 .

embodiment 3 :

according to embodiment 1 the expanding wheel device that described steel ball surface defect detects, described supporting member device inside front ends is provided with support wheel by coupling shaft 8 , described support wheel and described tested steel ball are fitted.

embodiment 4 :

according to embodiment 1 the expanding wheel device that described steel ball surface defect detects, described drive unit comprises direct current generator 6 , described direct current generator is arranged on the back side of back up pad, and described direct current generator is connected with described driving wheel by coupling shaft.

embodiment 5 :

according to embodiment 1-4 the expanding wheel device that described steel ball surface defect detects, the detection method of the expanding wheel device that described steel ball surface defect detects:

the schematic diagram that left expanding wheel, right expanding wheel contact with tested steel ball, as figure 2 shown in, described left expanding wheel, described right expanding wheel key component are the conical surfaces of both sides, friction gearing is relied between the conical surface and tested steel ball surface, due to expanding wheel particular design, now analyze and steel ball contact position situation of change, here expanding wheel is simplified to left and right two circular conical surfaces, situation of change when contacting with steel ball is as figure 3 , figure 4 , figure 5 shown in, setting up coordinate system, existing for convenience of analyzing the steel ball centre of sphere y axial change in location, fixes expanding wheel turning axle, and the steel ball centre of sphere is existed x direction of principal axis position changes, and (during actual expansion, the centre of sphere exists x axle and z shaft position is fixed).

expanding wheel is from figure 3 position turns to figure 4 during position, the centre of sphere with x wheelbase is from diminishing gradually; When expanding wheel is from figure 4 position turns to figure 5 during position, the centre of sphere with x the distance of axle becomes large gradually, so when expanding wheel forwards at figure 3 , figure 5 during position, the centre of sphere arrives x wheelbase is from reaching maximal value.

here steel ball radius is r , actual expanding wheel structure is as figure 6 shown in.

left side straight-line equation:

right side straight-line equation: ( 1 )

according to the contact relation of steel ball and expanding wheel, the centre of sphere is steel ball radius to two air line distances r , that is:

2

the centre of sphere o horizontal ordinate: ( 3 )

when y=0 , namely , the centre of sphere is positioned at x axle, and expanding wheel forward to ( a ) position time be centre of sphere distance x axle maximum, so the centre of sphere exists y position on direction of principal axis is not rotated with expanding wheel and changes.For detecting the steel ball of different size, DESIGN OF DEVELOPING-WHEEL only need meet formula ( 3 ) just can make steel ball stable rotation in whole testing process, do not produce vibration, improve accuracy of detection.
