Description

Известные устройства дл  измерени  длин не обеспечивают требуемой современными производственными услови ми точности измерени  вследствие значительных погрешностей, возникающих от провисани  измерительной ленты. Указанный недостаток почти полностью исключает возможность практического применени  известных устройств дл  измерени  больших длин.The known devices for measuring lengths do not provide the measurement accuracy required by current production conditions due to significant errors resulting from the sagging of the measuring tape. This disadvantage almost completely excludes the possibility of practical application of known devices for measuring large lengths.

Предлагаемое устройство дл  измерени  длин при помош,и провисающей стальной градуированной ленты позвол ет производить измерени  любых длин с необходимой точностью.The proposed device for measuring lengths with help and a sagging steel graduated tape allows measurements of any lengths with the required accuracy.

Достигаетс  это тем, что барабан, с которого сматываетс  измерительна  лента, подвешен на упругих элементах, и тем, что в устройстве применен указатель компенсации погрешности от провисани  ленты, стрелка которого взаимодействует с упругими элементами.This is achieved by the fact that the drum, from which the measuring tape is unwound, is suspended on elastic elements, and by the fact that the device uses an error compensation indicator due to sagging of the ribbon, the arrow of which interacts with elastic elements.

На чертеже схематически изображено описываемое устройство дл  измерени  длин, в двух проекци х.The drawing shows schematically the described device for measuring lengths in two projections.

К корпусу / устройства подвешена на плоских пружинах 2, 3 коробка 4, содержаща  бараба.н 5 со стальной градуированной измерительной лентой 6. На стенке коробки 4 на оси 7 установлена стрелка 8, короткое плечо которой снабжено штифтом 9, вход щим в паз 10 корпуса /.The case / device is suspended on flat springs 2, 3 box 4, containing drum 5 with steel graduated measuring tape 6. On the wall of box 4 on axis 7 there is an arrow 8, the short arm of which is provided with a pin 9 entering the groove 10 of the case /.

Пружины 2, 3 обеспечивают требуемое нат жение ленты 6 при перемещении коробки 4 с барабаном 5 влево в процессе производимых измерений. При этом стрелка 8, взаимодейству  с пружинами 2, 3, передвигаетс  по шкале // и указывает величину нат жени  ленты 6 при соответствующей деформации пружин. Положение ленты в этот момент фиксируетс  собачкой 12.The springs 2, 3 provide the required tension of the belt 6 when the box 4 with the drum 5 is moved to the left during the measurements made. In this case, the arrow 8, interacting with the springs 2, 3, moves along the // scale and indicates the tension value of the belt 6 with a corresponding deformation of the springs. The position of the tape at this moment is fixed by the dog 12.

Таким образоМ, стрелка 8  вл етс  указателем компенсации погрешности от провисани  ленты.Thus, arrow 8 is an indication of the error compensation from sagging the tape.

При измерени х устройство прижимают кронштейном 13 к краю измер емого издели  14 и при помощи руко тки 15 производ т нат жение измерительной градуированной ленты 6. Величина нат жени  ленты отражаетс  на Шкале 11.When measuring, the device is pressed by the bracket 13 to the edge of the measured product 14 and with the help of the handle 15 the tension of the measuring graduated tape 6 is applied. The tension of the tape is reflected on the Scale 11.

Результаты проведенных испытаний опытного образца устройства показали, что оно обеспечивает измерение изделий больших длин с точностью + 2 мм на длине 50 ж.The results of tests of the prototype of the device showed that it provides a measurement of products of large lengths with an accuracy of + 2 mm over a length of 50.

Пред метизобретеВИЯPrevention of Invention

Устройство дл  измерени  длин при помощи провисающей стальной градуированной ленты, сматываемой с барабана, отличающеес  тем, что, с целью повышени  точности измерений, барабан подвешен на упругих элементах и применен указатель компенсации погрешности от провисани  ленты, стрелка которого взаимодействует с упругими элементами.A device for measuring lengths with a sagging steel graduated tape unrolled from a drum, characterized in that, in order to improve the accuracy of measurements, the drum is suspended on elastic elements and an indication of the error compensation from sagging of the tape is applied, the arrow of which interacts with elastic elements.
