Abstract
The invention discloses a linear calibration device for a nonlinear torque dial, namely a device for recalibrating unequal interval scales on a dial of a nonlinear torque device. Shift of a tension apparatus dial driven by a step motor and a yarn winding roller driven by a servo motor are controlled by a closed-loop control system. Yarns are wound on a tension apparatus roller through a holding wheel; when a fan-shaped plate of one gear with fixed color is calibrated through a yarn tension measurer, the step motor is gradually shifted to the servo motor of the next gear to try running; and when the numerical value of a torque sensor reaches a set value and after the tension measurer verifies the numerical value, the fan-shaped plate with the color of the gear is fixed. The device solves the problems that an original nonlinear permanent magnetic tension apparatus cannot reflect the consistency of a batch of tension apparatuses in equidistance scribing and is inconvenient to use and manage; and the device can be used for recalibrating the scales with consistency after the tension apparatus is used for certain time and the performance of the tension apparatus is attenuated so as to avoid scrapping. Because of large application range and large number of the yarn tension apparatus, the device has certain economic benefit and social benefit.

1. the equidistant scale of original tensioner is made and is touched the concavo-convex line of tool, and the moment values of reflection can not be consistent linear, uses unfavorable management in batches.
2. original permanent magnetism tension roller uses uncertain amount decay of a period of time performance or tension force deficiency or tension force inconsistent, and not reproducible demarcation causes and uses and manage inconvenience in enormous quantities, even causes loss from spoilage huge.
Summary of the invention
The present invention is directed to the problems referred to above, designed a kind of semi-automatic not device of equi-distance scale that repeats to demarcate, make the permanent magnetism tensioner indicate the scale of linear change and the relation of moment, be convenient to use in enormous quantities and manage by the dial of unequal interval.Through suitable service time of moment properties in enormous quantities not during induced attenuation, can use this device to demarcate the restorability index again, reduce the loss, be convenient to manage, have potential economic benefit.
Technical solution of the present invention is achieved in that
The tension adjustment dish connects from deep low gear installation in position and stepper motor are coaxial, and it is stand-by that the tension adjustment dish is equipped with several colored different fan-shaped display scales; One one thread imports by gripping wheel, is wound on respectively on roller rod and the take up roll, and described take up roll is that servomotor drives through torque sensor.A few have enough frictional force on yarn winding take up roll behind the tension detector, and yarn withdraws from automatically.
According to tension adjustment man-machine interface set certain shelves the yarn tension value, determine adjustment disk central angle position, will be corresponding a kind of color scallop alignment, and tighten up a screw at the dial circumference and to follow closely or heat-sensitive glue is fixed.Carry out according to the order of sequence by shelves, finish to 10 grades or nearly when week.
