Description

II

Изобретение относитс к силоиэме рительной технике, в частности к устройствам дл измерени величины усилий, прикладываемых к рычагам ; управлени в любом направлении.The invention relates to a power engineering technique, in particular to devices for measuring the magnitude of the forces applied to the levers; control in any direction.

Известны динамометры, содержащие корпус в.виде сектора, шкалу усилий, выполненную на дуге свкто .ра, стрелку и плоскую пружину, установленную в плоскости биссектрисы угла сектора и закрепленную одним концом в вершине угла сектора, а другим Свободным концом - на стрелке шкалы D1.Dynamometers are known that contain a body in the form of a sector, a scale of forces made on an Svcto arc, an arrow and a flat spring installed in the plane of the sector angle bisector and fixed at one end at the top of the sector angle and at the D1 scale arrow.

Наиболее близким техническим решением к предлагаемому по своей сущности вл етс динамометрическа руко тка, содержаща упругий элемент , жестко закрепленный одним концом в Корпусе, а другим св занный с руко ткой с возможностью перемещени , передающий шток и индикатор перемещени 12.The closest technical solution to the proposed essence is a dynamometric handle containing an elastic element rigidly fixed at one end in the housing and the other connected with a movable handle, transmitting the rod and the movement indicator 12.

Недостатком известного устройства вл етс низка точность измерени .A disadvantage of the known device is low measurement accuracy.

Цель изобретени - повышение точности измерени .The purpose of the invention is to improve the measurement accuracy.

Указанна цель достигаетс тем, что в динамометрической руко тке корпус выполнен в виде кольцевого цилиндра с двум продольными пазами , в которых размещена вставка, This goal is achieved by the fact that in a dynamometric handle the body is made in the form of an annular cylinder with two longitudinal grooves in which the insert is placed,

10 св зывающа жестко упругий элемент и охватывающую с зазором корпус руко тку .10, which connects a rigidly resilient element and a housing enclosing with a gap.

На (Ьиг. 1 изображена динамометрическа руко тка, разрез; на фиг.2 (разрез А-А на фиг.1.In (lig. 1, a dynamometric handle is shown, a section; FIG. 2 (section AA in FIG. 1).

Claims

The torque wrench consists of a cylindrical case.1, at one end of which an elastic element 2 is co-centrically fixed, for example, a pin 3. On the second side of the concentrate case, the sleeve k, in which the transmitting rod S and indicator 6 are located, is located the handle 7, which is fastened with screws 8 to the insert 9, passing through the slots 10 of the housing 1 and secured to the elastic element with a screw 11. The elastic element 2 is made in the form of a cylindrical rod, on the fixed end of which there is a side on thread 12 for attachment of connecting nozzles on the other end along the axis of an opening 13, into contact with the tapered surface and the transmitting rod 5. The other end of the transmission rod contacts with the indicator 6 Torque handle operates as follows. With the aid of a transition nozzle attached to the threaded end 12, the dynamometric handle is attached to the control lever. When the control lever is moved by the handle 7, the elastic element 2 is deformed, which acts by opening 13 on the conical part 1ft of the transmitting rod 5 and moves it along the axis. The extent of this change depends on the force being applied and W1 ® | is an indicator 6. 34 The invention allows to increase the accuracy of force measurement. An inventive dynamometric handle comprising an elastic element rigidly fixed at one end in the housing and the other connected to a moving handle, transmitting rod and movement indicator, characterized in that, in order to improve the measurement accuracy, the housing is in the form of an annular cylinder with two longitudinal grooves, in which an insert is placed connecting the rigidly elastic element and the handle enclosing with the gap.
