Abstract

Изобретение относитс к измерительной технике и может быть использовано дл измерени размеров деталей с прерывистыми поверхност ми. Целью изобретени вл етс повышение точности измерени путем расширени диапазона регулировани усили демпфировани подвижного кор индуктивного преобразовател , а также повышение стабильности настройки путем исключени деформации кольцевой детали демпфера усили ми, передаваемыми от его регулировочного винта. Кольцева деталь демпфера образована двум част ми 9 и 10, образующими с корем 8 индуктивного преобразовател кольцевой зазор 11, форма и ширина которого регулируетс поворотом частей 9, 10 кольцевой детали демпфера. Выступами эти части контактируют с торцом неподвижной несущей пластины 3, на которой закреплен броневой ферромагнитный сердечник и катушка 4 индуктивности преобразовател . При ввинчивании винта 23 он раздвигает части кольцевой детали демпфера, обеспечива регулировку усили демпфировани . При этом исключаетс деформаци элементов демпфера. 1 з.п. ф-лы, 4 ил.The invention relates to a measurement technique and can be used to measure the dimensions of parts with intermittent surfaces. The aim of the invention is to improve the measurement accuracy by expanding the range of adjustment of the damping force of the movable core of the inductive transducer, as well as increasing the tuning stability by eliminating the deformation of the ring part of the damper by the forces transmitted from its adjusting screw. The ring part of the damper is formed by two parts 9 and 10, which form with the core 8 of the inductive converter an annular gap 11, the shape and width of which is controlled by turning the parts 9, 10 of the ring part of the damper. The protrusions of these parts are in contact with the end of the fixed carrier plate 3, on which the ferromagnetic armor core and the coil 4 of the inductance of the converter are fixed. When screwing in screw 23, it pushes parts of the ring part of the damper, providing adjustment of the damping force. This eliminates the deformation of the elements of the damper. 1 hp f-ly, 4 ill.

Claims

Claim

1. Inductive converter of linear dimensions, containing a sealed housing filled with damping fluid, an inductor with an armored ferromagnetic core and a ferromagnetic cylindrical armature interacting with it, an arm mounted at one end of which an armature is attached, a measuring tip fixed to the other at the end of the lever, a damper formed by an anchor and an annular part mounted on the core, covering the anchor with a gap, and a tuning mechanism the damper with the adjustment element brought out through the through hole in the wall of the case, so that in order to increase accuracy by expanding the range of adjustment of the damping forces, the ring part is made of two parts, adjoining one another in a plane passing through the axis of the armature, and mounted on the carrier plate with the possibility of movement in the transverse direction relative to the axis of the armature and fixation in a predetermined position.

2. The converter according to claim 1, characterized in that, in order to increase the stability of the setting by eliminating the annular deformation. damper parts by forces transmitted from the adjusting element, the latter is made in the form of a screw with

20 with a tip, both parts of the annular part are mounted with the possibility of rotation around the corresponding axes and have protrusions supported on the end face of the bearing plate and forming a groove with their edges to accommodate the conical tip of the screw, and the end face of the bearing plate is bounded by two sections of the cylindrical surface, the centers of which are located on corresponding axis of rotation of the parts of the annular part.
