It is bright.
Specific embodiment
Fig. 1 is the structural schematic diagram of frame of handwheel, and the frame of handwheel 1 includes steering wheel hub 11, steering wheel
Round edge 12 and the auxiliary plate 13 of steering wheel, the flatness of detection direction disk are the flatness of detection direction disk round edge 12, detection side
To the concentricity that the concentricity of disk is between detection direction disk center 11 and steering shaft, and detection device provided by the invention is then
It can be realized above-mentioned detection process, be now described below:
- Fig. 3 referring to fig. 2, detection device are mainly made of fixed disk 4, cubing main body 2 and supportive body 3, the cubing master
Body 2 includes 21, four area detectors 22 of coaxial detector, support plate 23 and the support shaft 24 in support plate, wherein
Coaxial detector 21 is elongated cylindrical body, the axis collinear of axis and support shaft 24, coaxial detector 21 and support shaft 24
Between be also connected with rotary body, the rotary body includes central axis 26, clamping rings 27, upper turnbarrel 28 and lower rotary sleeve
Cylinder 29, the both ends of the central axis 26 are connected with the top of the bottom end of coaxial detector 21 and support shaft 24 respectively, clamping rings
27 are set in outside central axis 26, are arranged with the upper turnbarrel 28 being arranged above and below and lower turnbarrel 29 outside clamping rings 27,
And upper turnbarrel 28 is connected by radius regulating arm 25 with two of them area detector 22, lower turnbarrel 29 equally passes through
Radius regulating arm 25 is connected with other two area detector 22, and area detector 22 described in four is U-shaped, and plane is examined
It surveys inside device 22 and is equipped with pressure sensor 220, radius regulating arm 25 is equipped with multiple adjustment holes, clamping screw 30 and the not people having the same aspiration and interest
The locking of knothole cooperates adjustable area detector 22 to the distance of central axis 26, the upper turnbarrel 28 and lower turnbarrel
29 can rotate, to adjust the position of area detector 22；The supportive body 3 between fixed disk 4 and support plate 23,
