Изобретение относитс к области контактной сварки и может быть использовано преимущественно при контроле качества точечной и шовной сварки деталей из тонколистового материала.The invention relates to the field of resistance welding and can be used mainly in the quality control of spot and seam welding of parts from thin sheet material.
Известно устройство дл контрол качества точечной и шовной сварки с применением измерительных элементов, преобразующих в электрический сигнал величину смещени электродов и содержащих датчик перемещени , установленный на подвижной головке привода сжати электродов , согласующее устройство, усилитель мощности, задающее устройство, блок сравнени и блок регистрации дефектов 1. A device for quality control of spot and seam welding with the use of measuring elements that convert the magnitude of the displacement of electrodes into an electrical signal and contain a displacement sensor mounted on a moving head of an electrode compression drive, a matching device, a power amplifier, a driver, a comparison unit and a defect detection unit 1 is known. .
Оценка качества сварки обусловливаетс технологическими особенност ми, типом оборудовани , толщиной и маркой свариваемых материалов, что вл етс одним из недостатков известного устройства. Кроме того, это устройство недостаточно надежно при проведении сварки на машинах с малой жесткостью вторичного контура, при наличии значительных сил трени и инерции в подвижных част х механизма ежати .The evaluation of the quality of welding is determined by the technological features, the type of equipment, the thickness and the brand of materials being welded, which is one of the drawbacks of the known device. In addition, this device is not sufficiently reliable when conducting welding on machines with low rigidity of the secondary circuit, in the presence of significant forces of friction and inertia in moving parts of the scooter mechanism.
Целью изобретени вл етс повышение надежности контрол качества точечной и шовной сварки независимо от конструктивно-технологических особенностей оборудовани , режимов сварки и толщины свариваемых материалов.The aim of the invention is to improve the reliability of quality control of spot and seam welding, regardless of the design and technological features of the equipment, welding conditions and thickness of the welded materials.
Поставленна цель достигаетс тем, что в предлагаемом устройстве датчик контрол выполнен в виде электрокинетического преобразовател ускорени , который своей осью ориентирован перпендикул рно к поверхности свариваемых деталей и жестко св зан с подвижным электродом мащины.This goal is achieved by the fact that, in the proposed device, the monitoring sensor is made in the form of an electrokinetic acceleration converter, which is oriented perpendicular to the surface of the welded parts with its axis and is rigidly connected to the movable electrode of the maschine.
На фиг. 1 представлена блок-схема устройства; на фиг. 2 схема установки датчика .FIG. 1 is a block diagram of the device; in fig. 2 diagram of the sensor installation.
Устройство состоит из датчика 1 контрол , согласующего устройства 2, усилител 3 мощности, блока 4 питани , задающего устройства 5, блока 6 сравнени и блока 7 регистрации дефектов. Свариваемые детали 8 зажаты между электродами 9 и 10.The device consists of a control sensor 1, a matching device 2, a power amplifier 3, a power supply unit 4, a driver 5, a comparison unit 6 and a defect detection unit 7. Weldable parts 8 are clamped between electrodes 9 and 10.
Устройство работает следующим образом .The device works as follows.
Дл измерени ускорени перемещени подвижного электрода служит датчик 1, представл ющий собой электрокинетический преобразователь ускорени с жесткими торцовыми стенками, который осью чувствительности ориентирован перпендикул рно к поверхности свариваемых деталей и жестко св зан с подвижным электродом 8.To measure the acceleration of the moving electrode, the sensor 1 is an electrokinetic acceleration transducer with rigid end walls, which is oriented perpendicularly to the surface of the welded parts 8 and the axis of sensitivity.
При протекании сварочного тока /ев через детали 8, зажатые между электродаWhen the flow of welding current / s through the parts 8, clamped between the electrode
