Description

Technical Field

[0001] This utility model relates to the technical field of non-destructive testing, and in particular to a non-destructive testing probe position adjustment device. Background Technology

[0002] Non-destructive testing probes are devices that compare non-destructive testing signals emitted by the object to be tested with signals of internal defects in the object, thereby detecting internal defects. They use electrical oscillations to excite high-frequency ultrasonic waves in the transmitting probe. After entering the interior of the object being tested, if a defect is encountered, the ultrasonic waves will be reflected, scattered, or attenuated.

[0003] Existing probe position adjustment devices, such as the probe position adjustment device disclosed in utility model patent application number 202120656362.1, mainly include a fixed base, on which a threaded sleeve and lead screw assembly are vertically arranged. The first end of the threaded sleeve and lead screw assembly is fixed to the fixed base, and the second end of the threaded sleeve and lead screw assembly is provided with a rotating handle. The second end of the threaded sleeve and lead screw assembly is provided with a fixing component for fixing the exposure probe. In use, the exposure probe can be clamped in the ring body. By adjusting the clamping component, a pair of ring rods can be tightened, thereby reducing the inner area of ​​the ring body. The relative rotation of the threaded sleeve and lead screw assembly will adjust the relative position of the fixing component and the fixed base, thereby adjusting the relative distance between the exposure probe and the fixed base, thus realizing the adjustment of the height of the fixed exposure probe.

[0004] However, most existing probes are moved on the workpiece by staff, and the movement trajectory is prone to deviation, making it difficult to guarantee the accuracy of flaw detection. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a non-destructive testing probe position adjustment device that not only adjusts the distance between the probe and the workpiece to be tested, improving the flexibility of the device, but also facilitates the movement of the probe on the surface of the workpiece to be tested, thereby improving the detection accuracy.

[0006] This utility model discloses a non-destructive testing probe position adjustment device, including a protective mechanism; it also includes a placement mechanism, a lifting mechanism, two sets of clamping mechanisms, and two sets of driving mechanisms. The placement mechanism is installed on the protective mechanism and fixes the probe. The lifting mechanism is on the protective mechanism and drives the placement mechanism to move up and down. Both sets of clamping mechanisms are installed on the protective mechanism and drive the protective mechanism to move. The two sets of driving mechanisms are respectively installed on the two sets of clamping mechanisms and drive the clamping mechanisms to move. The operator places the non-destructive testing probe in the placement mechanism, and then places the two sets of clamping mechanisms on the workpiece to be tested. When the surface of the workpiece is narrow, the two sets of clamping mechanisms can clamp the workpiece. The lifting mechanism is activated to drive the placement mechanism to move up and down, adjusting the distance between the probe and the workpiece to be tested. The two sets of driving mechanisms are activated, driving the two sets of clamping mechanisms to move, and the two sets of clamping mechanisms drive the probe to move.

[0007] Preferably, the protective mechanism includes a base, a limiting cylinder, a protective cover, and a protective box.

The protective cover seals the limiting cylinder to prevent damage to the placement mechanism and the probe. The protective box prevents damage to the lifting mechanism and other related equipment.

[0008] Preferably, the mounting mechanism includes a lifting cylinder, a pad, three sets of slide rails, and a rack. The lifting cylinder is slidably installed inside the limiting cylinder. The top of the pad is connected to the bottom of the lifting cylinder. All three sets of slide rails are installed on the lifting cylinder and slidably installed in the limiting grooves. The rack is installed on the lifting cylinder. The operator places the probe inside the lifting cylinder. The pad protects and supports the bottom of the probe. The three sets of slide rails facilitate the lifting and lowering of the lifting cylinder. The lifting mechanism and the rack mesh and drive the lifting cylinder to rise and fall through the rack.

[0009] Preferably, the lifting mechanism includes a servo motor, a first reducer, a bracket, a first drive shaft, and a gear. The servo motor is mounted on the protective housing. The bottom end of the first reducer is connected to the top end of the base, and the bottom end of the bracket is connected to the top end of the base. The first drive shaft is rotatably mounted on the bracket, and the gear is mounted on the first drive shaft.

The first drive shaft drives the gear to rotate, and the gear and rack mesh to drive the rack and lifting cylinder to move up and down, adjusting the distance between the probe and the workpiece to be measured.

[0010] Preferably, the clamping mechanism includes two sets of sliders, a positioning pin, an adjusting knob, a connecting frame, and multiple sets of rubber rollers.

The drive mechanism drives the connected rubber rollers to rotate, and the rubber rollers drive the connecting frame and the protective mechanism forward, facilitating continuous detection of the workpiece by the probe. When the workpiece to be tested is narrow, the operator adjusts the distance between the two clamping mechanisms according to the width of the workpiece, and then uses the positioning pin to fix the two sets of sliders. The operator then rotates the adjusting knob to bring the multiple sets of rubber rollers into contact with the sides of the workpiece. The multiple sets of rubber rollers on the two clamping mechanisms cooperate to clamp the workpiece. The rubber has anti-slip properties, which enhances the friction between the rubber rollers and the workpiece, improving stability. Then, the drive mechanism drives the rubber rollers to rotate, moving the probe forward.
