Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, an ultrasonic probe pressing device comprises a connecting base 1, a pressure regulating device 2 and an ultrasonic probe 3, wherein the connecting base 1 is cylindrical, a fixing groove 11 is formed in the bottom of the connecting base 1, as shown in fig. 2a, a positioning shaft 12 is arranged on the upper portion of the connecting base, and fastening pieces 13 are arranged on two sides of the connecting base. The pressure regulating device 2 is also cylindrical in shape and has the same radius. The upper part of the pressure regulating device 2 is provided with an opening, the inside is a cavity, the bottom is sealed, the bottom is provided with a groove 21, the groove 21 is matched and connected with the positioning shaft 12, and the pressure regulating device can be easily taken down and put down. An adjusting body is arranged in the pressure adjusting device 2, and the adjusting body can be small block or powder; the metal powder 22 is used in this embodiment, and the weight of the pressure regulating device 2 is conveniently controlled. In order to prevent the powder 22 from falling down when the ultrasonic probe 3 is operated and moved, a sealing cover is provided on the upper portion of the pressure adjusting device 2, which may be a conventional cover, in this embodiment, a sealing tape, for convenient operation. The upper part of the ultrasonic probe 3 is placed in the fixing groove 11, the fixing groove 11 is a box-shaped groove punched at the bottom of the connection base 1, the size of the box-shaped groove is suitable for placing the ultrasonic probe 3 of a plurality of types, and the two sides of the fixing groove 11 are provided with fasteners 13, specifically fastening bolts, through which the ultrasonic probe 3 can be fixed in the fixing groove 11.
The ultrasonic probe 3 is connected to the ultrasonic flaw detector 4.
The working principle of the device is as follows: the inspector is connected together ultrasonic probe 3 and ultrasonic flaw detector 4 through the cable, then ultrasonic probe 3 places in the fixed slot 11 of connecting in the base 1, fixes it on connecting base 1 through adjusting the fastening bolt about, and guarantees its axis and the coincidence of the axis of connecting base 1, places regulator 2 on connecting base 1 afterwards, and the clearance fit through location axle 12 and recess 21 between the two is connected to together. After the operation is finished, the probe is calibrated. Opening a switch of the ultrasonic flaw detector 4, smearing a coupling agent between the ultrasonic probe 3 and the standard test block, calibrating the probe according to the calibration steps of the ultrasonic probe 3, stopping adding or reducing the metal powder 22 when the display thickness of the primary reflection bottom wave is equal to the thickness of the standard test block, enabling the gravity of the connecting base 1 and the pressure regulating device 2 to be equal to the finger pressing force, and sealing the upper end of the pressing block by using a transparent adhesive tape to prevent the metal powder 22 from being sprayed out when the operation is careless. And after the position is changed, if the display thickness of the primary reflected bottom wave is still equal to the thickness of the standard test block, the calibration is finished.
