Description
Известно устройство дл компенсации температурных деформаций узлов металлорелтещих станков с помощью электрических батарей .A device is known for compensating for temperature deformations of assemblies of metal-relaxing machines using electric batteries.
Описываемое устройство обеспечивает повышение точности компенсации, дл чего в характерных точках стабилизируемого узла закреплены одним рабочим спаем полупроводниковые термоэлектрические батареи, другой рабочий спай батарей соединен с ребрами теплообмена стабилизируемого узла.The described device provides an increase in the accuracy of compensation, for which, at the characteristic points of the stabilized node, semiconductor thermoelectric batteries are fixed by one working junction, another junction of batteries is connected to the heat exchange edges of the stabilized node.
На фиг. 1 и 2 схематично изображено предлагаемое устройство.FIG. 1 and 2 schematically depict the proposed device.
Устройство содержит стабилизируемый узел ), полупроводниковые батареи 2, блок питани 3 и ребра 4 теплообмена.The device contains a stabilized assembly), semiconductor batteries 2, power supply unit 3 and heat exchange fins 4.
Нагрев или охлаждение точек стабилизируемого узла производитс за счет изменени величины и направлени посто нного тока в батаре х 2, имеющих две полупроводниковые ветви, одна из которых обладает электронной, а друга дырочной проводимостью в местах контакта. Управление изменением тока производитс с помощью терморезисторов , установленных в ответственных точках станка.The points of the node to be stabilized are heated or cooled by varying the magnitude and direction of the direct current in batteries x 2 having two semiconductor branches, one of which has electronic and other hole conduction at the points of contact. Current change control is performed using thermistors installed at critical points in the machine.
