(54) DEVICE TO CONTROL VIBRATION PARAMETERS

The invention relates to a technique for controlling vibrations, in particular when welding with an overlap of ultrasonic vibrations, and may find application in measuring the parameters of the mechanical vibrations of a welding electrode. A device for controlling vibration parameters is known, comprising a base rigidly connected to a controlled welding electrode, a housing mounted on a base, made in the form of a sleeve, inside which a light source with an optical system, mounted on a base, inertial and elastic elements are placed, a photoelectric converter located along the light beam and fixed on the inertial element, and a block indicator connected to the output of the photoelectric converter Ll The disadvantage is The device is that the metrological characteristics do not provide it. the required accuracy of vibration parameters control, because the use of a special form of the inertial element does not provide a significant improvement in performance, since the analog photoelectric converter has the most significant effect, since it is influenced by the environment (smoke and dust, etc.). In addition, a significant impact on the productivity and accuracy of measurements is made by the complexity of setting up the sensor and recording equipment, the adjustment of the measurement range is small. The purpose of the invention is to increase the current, expand the range and reduce the measurement time. This goal is achieved by the fact that the device for controlling vibration parameters is equipped with a fiber-optic ruler and adjusting screws associated with resilient elements and installed

On the cores forming the core, the inertial element has a central opening in which an optical ruler is located, directed by the end face perpendicular to the light beam and optically coupled to the photoelectric converter.

.In FIG. The device is shown, look around, cut; figure 2 - block diagram indicator.

A device for monitoring vibration parameters, contains a base I, rigidly connected to a controlled welding electrode 2, a housing 3 mounted on a base 1, made in the form of a sleeve, inside which is placed the source 4 of light with an optical system, mounted on the base G and 1, inertial element 5 and elastic elements 6 and 7, a photoelectric converter 8 located along the light beam and fixed on the inertial element 5, and a block indicator 9, connected to the output of the photoelectric converter, fiber op The ruler 10 and the adjusting screws II and 12 are connected to the elastic elements and mounted on the forming sleeves of the housing 3, and in the inertial element 5 there is a central opening in which the ruler 10 is located, directed by the end face perpendicular to the light beam and connected optically with the photoelectric converter 8, the blocking indicator 13 includes an amplifier 14, a logic circuit 15, a counter counter 16, a digital indicator 1 7,

The device works as follows.

When ultrasonic vibrations of the welding electrode 2 are excited, the circuit of the light source 4 is turned on. The light flux from the light source in the form of a narrow beam is directed onto the sensing surface of the ruler 10 located in the inertial element 5. The ruler 10 is formed of horizontal rows of light-conducting fibers of equal thickness.

Through the light guide fibers, a light j-stream is transmitted to a photoelectric signal which is amplified by an amplifier J4 and transmitted to a logic processing circuit 15 5, in which the direction of movement and the number of fibers of the ruler 10 illuminated by a light bundle are determined. fixed by reversing the account, chick 16. Information about transferring / FAT is indicated by digital indicator 17

The device will increase ka, 5 honestly welded joints.
