Description

Technical Field

[0001] This utility model relates to the field of phased array ultrasonic testing technology, specifically to a clamping device for a phased array probe. Background Technology

[0002] A phased array probe is a component of phased array ultrasonic testing. Together with the phased array instrument and encoder, it forms a phased array ultrasonic testing system, enabling recordable ultrasonic testing of the object being tested. Phased array probes require a clamping device to connect to the encoder and generally do not have a positioning device.

[0003] When a phased array probe is used to inspect a workpiece, it is necessary to ensure that the distance between the front end of the phased array probe and the center of the weld seam remains constant during the inspection process. The error is generally not allowed to exceed 1mm. Traditional clamping devices usually rely on manual hand-held movement, which makes it difficult to keep the front distance constant. During the inspection process, it is necessary to constantly check whether the front distance is correct. The operation is cumbersome, prone to errors, and the positioning is inaccurate. Utility Model Content

[0004] To overcome the problems of existing phased array probe clamping devices, which rely on manual hand-held movement to maintain a constant front distance, are cumbersome to operate, prone to errors, and have inaccurate positioning, this utility model provides a phased array probe clamping device. By setting a laser pointer, a linear light beam can be projected onto the workpiece surface during the detection process, allowing clear observation of whether the probe's movement path deviates from the correct position when the phased array probe moves, greatly improving detection efficiency.

[0005] This utility model provides the following technical solution:

[0006] This utility model proposes a clamping device for a phased array probe, including a phased array probe, a probe clamp for clamping the phased array probe, and a laser pen clamp fixed to the top of the probe clamp. An encoder is provided at the rear end of the phased array probe, and a laser pen is fixed inside the laser pen clamp.

[0007] Preferably, the probe clamp includes a first fixing plate fixed to the left side of the phased array probe and a second fixing plate fixed to the right side of the phased array probe. The first fixing plate is L-shaped and has an insertion port at the top.

[0008] The second fixing plate includes an L-shaped plate and a laser pointer fixing plate fixed to the top of the L-shaped plate and extending to the left. The left end of the laser pointer fixing plate passes through the socket to achieve engagement. The top of the laser pointer fixing plate has a laser pointer fixing block for fixing the laser pointer clamp.

[0009] Preferably, both the first fixing plate and the second fixing plate are fixedly connected to the phased array probe by screws.

[0010] Preferably, the upper end of the laser pointer fixing block has a threaded hole, the lower end of the laser pointer clamp has a threaded hole, and the laser pointer fixing block and the lower end of the laser pointer clamp are fixedly connected by screws.

[0011] Preferably, a connecting rod is fixed between the first fixed plate and the L-shaped plate, the connecting rod being located at the rear end of the first fixed plate and the L-shaped plate, and the connecting rod being fixedly connected to the encoder.

[0012] Preferably, the laser pointer can switch between dot, line, and cross beam patterns.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model is small in size, light in weight, and quick to load and unload. It does not require processing of the original phased array probe and can be used to clamp phased array probes of various sizes. During the detection process, it can project light onto the workpiece to assist in positioning, solving the problems of inefficiency, need for repeated adjustment, easy detachment, and inaccurate positioning of traditional clamping devices.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] See Figure 1-2 A clamping device for a phased array probe 1 includes a phased array probe 1, a probe clamp 2 for clamping the phased array probe 1, and a laser pen clamp 3 fixed to the top of the probe clamp 2. An encoder 4 is provided at the rear end of the phased array probe 1, and a laser pen 31 is fixed inside the laser pen clamp 3.

[0022] See Figure 1-3In one embodiment of the present invention, the probe clamp 2 includes a first fixing plate 21 fixed to the left side of the phased array probe 1 and a second fixing plate 22 fixed to the right side of the phased array probe. The first fixing plate 21 is L-shaped and has an insertion port 211 at the top.

[0023] The second fixing plate 22 includes an L-shaped plate 221 and a laser pointer 31 fixing plate 222 fixed to the top of the L-shaped plate 221 and extending to the left. The left end of the laser pointer 31 fixing plate 222 passes through the insertion port 211 to achieve engagement. The top of the laser pointer 31 fixing plate 222 has a laser pointer 31 fixing block for fixing the laser pointer clamp 3.

[0024] See Figure 1-2 In order to accommodate phased array probes 1 of different widths and sizes, based on the previous embodiment, the first fixing plate 21 and the second fixing plate 22 are both fixedly connected to the phased array probe 1 by screws.

[0025] See Figure 1-2 In order to adjust the angle of the laser pointer 31, in one embodiment of the present invention, the upper end of the laser pointer 31 fixing block has a threaded hole, the lower end of the laser pointer clamp 3 has a threaded hole, and the laser pointer 31 fixing block and the lower end of the laser pointer clamp 3 are fixedly connected by screws.

[0026] Before testing, adjust the positions of the laser pointer clamp 3 and the laser pointer 31, align them with the target position, and then tighten the screws to achieve adjustment.

[0027] See Figure 1-2 In one embodiment of the present invention, a connecting rod 41 is fixed between the first fixing plate 21 and the L-shaped plate 221. The connecting rod 41 is located at the rear end of the first fixing plate 21 and the L-shaped plate 221, and the connecting rod 41 is fixedly connected to the encoder 4.

[0028] In one embodiment of this utility model, the laser pointer 31 can switch between dot, line, and cross beams to adapt to different workpieces.

[0029] The laser pointer, phased array probe and encoder mentioned above are all existing equipment, and those skilled in the art can understand their working principles, so they will not be described in detail here.

[0030] See Figure 4Before operation, clamp the device onto the phased array probe, and place the probe on the workpiece. When placing the probe, the central axis of the laser pointer should be perpendicular to the weld seam. Adjust the probe's position so that the linear beam projected by the laser pointer is parallel to the weld seam and located at its center. During operation, connect the phased array probe to the device and manually move the probe parallel to the weld seam. During this movement, the phased array probe emits ultrasonic waves that penetrate the workpiece. If a defect is detected, the probe will receive the ultrasonic defect echo signal. It is important to note that the distance between the phased array probe and the weld seam must remain constant throughout the probe's movement. The laser beam projected by this device effectively aids in observation and prevents the phased array probe from deviating from its correct position during movement.

[0031] The aforementioned workpieces can be welded metal components such as steel and non-ferrous metals. Phased array ultrasonic testing is used to detect internal defects in the weld and to locate, characterize, and quantify the defects.

Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
