Description

Technical Field

[0001] The invention relates to the technical field of nondestructive testing, in particular to a probe clamping and scanning device for ultrasonic nondestructive testing. Background Art

[0002] Ultrasonic testing is a technology that studies the reflected, transmitted and scattered waves through the interaction between ultrasonic waves and test pieces. It detects macroscopic defects, measures geometric characteristics, detects and characterizes changes in organizational structure and mechanical properties of test pieces, and then evaluates their specific applicability.

[0003] For example, the application number is 202321201423.0, a probe clamping and scanning device for ultrasonic non-destructive testing, the probe is placed between the baffle and the clamp, the clamp is driven to move to the left by the cylinder, and the probe is clamped and fixed by the baffle and the clamp.

[0004] It has the following defects:

[0005] For a rectangular probe, the baffle and the clamp can be clamped on two sides of the probe to firmly clamp the probe. Although the probe can be clamped firmly, the two sides of the probe are blocked, which will reduce the heat dissipation effect of the probe. In addition, if the probe is cylindrical in shape, the surface clamping of the baffle and the clamp becomes a point clamping, and the baffle and the clamp become two clamping points clamped on the outer wall of the probe. Although the probe can be clamped in this way, the probe is not clamped stably enough and is easily tilted due to force.

[0006] Therefore, we proposed a probe clamping and scanning device for ultrasonic non-destructive testing to solve the above problems. Summary of the invention

[0029] Example

[0030] like Figure 1-5 As shown, an embodiment of the present invention provides a probe clamping and scanning device for ultrasonic nondestructive testing, comprising a workbench 1, on which a work frame 2 is fixedly arranged, and a placement plate 3 is slidably arranged at the bottom inner side of the work frame 2 through a slider;

[0031] A clamping plate 4 is arranged above the placement plate 3 and is used to clamp the ultrasonic probe. A plurality of the clamping plates 4 are provided, and the plurality of the clamping plates 4 are arranged in a circular array. A limiting plate 5 is provided above the clamping plate 4, and one end of the clamping plate 4 is located inside the limiting plate 5, and the other end of the clamping plate 4 passes through the limiting plate 5;

[0032] A driving disk 6 is arranged above the clamping plate 4 and is used for driving the clamping plate 4 to move. A plurality of slide grooves 7 are provided on the driving disk 6. One end of the clamping plate 4 located on the inner side of the limiting plate 5 is slid in the slide groove 7 on the driving disk 6 in sequence through a slide rod 8. A fixed disk 9 is arranged above the driving disk 6. A groove is provided on the fixed disk 9. The driving disk 6 is rotatably arranged in the groove. A fixing frame 10 is fixedly provided on the fixed disk 9. A servo motor 11 is fixedly provided on the inner side of the fixing frame 10. The output end of the servo motor 11 passes through the fixed disk 9 and docks with the driving disk 6. A lifting component is provided on the fixing frame 10.

[0033] By configuring the clamping plate 4, the limit plate 5, the drive disk 6, the slide groove 7, the slide rod 8, and the servo motor 11, the ultrasonic probe can be clamped by multiple clamping plates 4 at the same time, so that the clamping and fixing of the ultrasonic probe has multiple clamping points. The multiple clamping points not only do not affect the heat dissipation of the ultrasonic probe during use, but can also be suitable for ultrasonic probes of different shapes, and the clamped ultrasonic probe is more stable.

[0034] The lifting assembly includes a cylinder 12, which is fixedly arranged on the working frame 2. The output end of the cylinder 12 passes through the working frame 2 and is fixedly connected to the fixing frame 10. The cross section of the clamping plate 4 is L-shaped. The setting of the cylinder 12 can drive the ultrasonic probe clamped by the clamping plate 4 to move up and down, so as to maintain the optimal detection distance between the ultrasonic probe and the object to be detected.

[0035] like Figure 4 As shown, the fixing frame 10 includes two fixing plates 101 and a plurality of connecting rods 102, and the two fixing plates 101 are arranged in an upper and lower position. The plurality of connecting rods 102 are located between the two fixing plates 101, and the two ends of the connecting rods 102 are respectively fixedly connected to the two fixing plates 101, and the servo motor 11 is fixedly arranged on the fixing plates 101. The fixing frame 10 is more solid and stable when in use by fixing the two fixing plates 101 with the plurality of connecting rods 102.

A driving motor 13 is fixedly provided inside the workbench 1, and the output end of the driving motor 13 is connected to the rotating disk 110. The arrangement of the rotating disk 110, the driving motor 13, and the connecting plate 14 allows the detection object on the placement plate 3 to move back and forth in the horizontal direction, thereby improving the detection range of the ultrasonic probe for the detection object on the placement plate 3.

[0037] Working principle of the utility model: when it is necessary to clamp the ultrasonic probe, firstly, one end of the ultrasonic probe is placed on the limit plate 5, and then the servo motor 11 is started. The start of the servo motor 11 drives the driving disk 6 to rotate, and the rotation of the driving disk 6 drives the clamping plate 4 on the driving disk 6 to tighten inwardly. The tightening of the clamping plate 4 makes the clamping plate 4 clamp the ultrasonic probe placed on the limit plate 5, until multiple clamping plates 4 clamp the ultrasonic probe placed on the limit plate 5, and then the servo motor 11 can be turned off (when the ultrasonic probe needs to be removed, the servo motor 11 is started in the reverse direction). Motor 11 is sufficient), when it is necessary to detect the detection object on the placement plate 3, start the ultrasonic probe and the drive motor 13, the start of the ultrasonic probe detects the detection object on the placement plate 3, the start of the drive motor 13 drives the rotating disk 110 to rotate, the rotation of the rotating disk 110 drives one end of the connecting plate 14 to make a circular motion, the movement of the connecting plate 14 drives the placement plate 3 to make repetitive back and forth motion on the work frame 2, the movement of the placement plate 3 drives the detection object thereon to move, the movement of the detection object enables the ultrasonic probe to detect the detection object in multiple directions.
