Description
Изобретение относитс к область станкостроени и предназначено дл использовани в станках с измен ющимс вектором силы резани по модулю и фазе, в частности в станках расточной группы.The invention relates to the field of machine tool construction and is intended for use in machine tools with varying cutting force vector in magnitude and phase, in particular, in boring machine tools.
Известно устройство дл определени динамических характеристик металлорежущих станков без применени резани , в которых имитаци силовых воздействий на станок осуществл етс при помощи электромагнита, имеющего обмотки посто нного и переменного тока, создаюгоие посто нную и переменную силы A device for determining the dynamic characteristics of metal-cutting machines without the use of cutting, in which the imitation of force effects on the machine is carried out using an electromagnet having DC and AC windings, creating a constant and variable force
В этом устройстве сердечник электромагнита с обмотками посто нного и переменного тока устанавливаетс на суппорт или стол станка. Вращающа с оправка, закрепленна в шпинделе , вл етс корем электромагнита.In this device, the core of an electromagnet with DC and AC windings is mounted on a caliper or table machine. The rotating mandrel fixed in the spindle is the core of the electromagnet.
Однако это устройство имеет следующие недостатки: при работе станка силовое воздействие не измен ет своего направлени и координаты точки приложени . Это не позвол ет имитировать нагрузки при расточных работах , где силовое воздействие приложено в одной точке на оправке иHowever, this device has the following disadvantages: during the operation of the machine, the force action does not change its direction and the coordinates of the point of application. This does not allow to simulate the load during the boring work, where the force effect is applied at one point on the mandrel and
измен ет свое направление синхронно с вращением шпиндел .changes its direction synchronously with the spindle rotation.
Известно также устройство дл создани радиальной нагрузки, позвол ющее измен ть направление силового воздействи синхронно с вращением . .шпиндел . В этом устройстве сердечник выполнен в виде двух щек с перемычкой . На перемычку установлены It is also known a device for creating a radial load, which makes it possible to change the direction of the force action synchronously with the rotation. spindle In this device, the core is made in the form of two cheeks with a jumper. Jumper installed
10 соответствующие обмотки посто нного и переменного тока. В щеках сердечника соосные цилин;зЕрические отверсти , внутри которых вращаетс корь, выполненный в виде 10 corresponding DC and AC windings. In the cheeks of the core, coaxial Zilin; zericheskie holes, inside which the measles rotates, made in the form
15 шихтованной шпонки на оправке, закрепленной на шпинделе станка. Силовое воздействие возникает в результате залшкани магнитного потока через. мини ашьный воздушный за20 зор « между шпонкой и отверстием. Таким образом, при вращении оправки синхронно с изменением положени шпонки- кор измен етс направление силового воздействи на станок 2. 15 laminated keys on a mandrel mounted on the spindle of the machine. Forceful exposure occurs as a result of zalcane magnetic flux through. Mini air gap “between the key and the hole. Thus, when the mandrel rotates synchronously with the change in the position of the key, the direction of the force action on the machine 2 changes.
