Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to operate and measure accurate shaped roll contour profile measuring instrument.
For achieving the above object, the technical solution used in the present invention is: shaped roll to be measured is horizontally fixed on frame by top, and a side of shaped roll to be measured flatly is provided with measurement bay.
Gear shaft is arranged on measurement bay by bearing seat and bearing, and gear is equipped with at the two ends of gear shaft, the gear at gear shaft two ends and the corresponding engagement of two of left and right tooth bar, and two of left and right tooth bar is horizontally fixed on the inboard of frame, and gear shaft is driven by the through-core hole motor.
Ball screw is arranged on measurement bay by bearing and bearing seat, and ball screw is between shaped roll and gear shaft to be measured, and gear shaft, ball screw and shaped roll to be measured are parallel to each other, and ball screw is driven by lead screw motor.Ball screw is equipped with nut, and the reflective laser displacement transducer is fixed on nut, the axial line of the utilizing emitted light of reflective laser displacement transducer by shaped roll to be measured and vertical with the axis of roll; Between nut and gear shaft for being slidably matched.
Described lead screw motor is stepper motor or is servomotor.
Described through-core hole motor is the through-core hole stepper motor or is the through-core hole servomotor.
Owing to adopting technique scheme, while rotating under the driving of ball screw in lead screw motor, due to the guide effect of gear shaft to nut, with the supporting nut of ball screw and the reflective laser displacement transducer of upper installation thereof, will move along the axis of ball screw.Can be determined the straight-line displacement u of reflective laser displacement transducer by the helical pitch of the corner of lead screw motor and ball screw.The axial line of the utilizing emitted light of reflective laser displacement transducer by shaped roll to be measured and vertical with the axis of roll.If the luminous point of reflective laser displacement transducer is d to the distance in shaped roll axle center to be measured
0, when the luminous point of reflective laser displacement transducer is d to the measured value on shaped roll surface, the roller radius of corresponding measurement point is d
0-d.Notice that shaped roll to be measured is axialy symmetric part, therefore, can determine the physical dimension of shaped roll according to measured value d and straight-line displacement u.Owing to adopting the reflective laser displacement transducer, and lead screw motor is stepper motor or is servomotor, adds the helical pitch precision machining of ball screw, so the little measurement result of measurement size error accurately and reliably.
The present invention also is connected with the gear at two ends by the gear shaft be arranged on measurement bay, gear and the tooth bar engagement be fixed on frame, gear shaft is driven by the through-core hole motor, the rotation of through-core hole motor is by driven wheel and then drive measurement bay along the tooth bar translation, thereby adapt to the variation of institute's survey roll maximum outside diameter size, and simple in structure.
Therefore, that the present invention has is simple in structure, easy to operate, high efficiency, measurement result characteristics accurately, can not only guarantee the machining precision of roll, and can further guarantee the dimensional accuracy of rolled product.
