Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic detection, in particular to a small and portable ultrasonic scanning device. Background Art

[0002] In the current ultrasonic testing process, there are two types of ultrasonic testing: non-encoded ultrasonic testing and encoded ultrasonic testing. The common problem encountered in encoded ultrasonic testing is that the asynchronous movement of the probe and the encoder affects the specific position information of the detected workpiece, the poor coupling between the probe and the detected workpiece causes the loss of the detection signal, and probes of different specifications need to be installed on the corresponding scanning device.

[0003] For example, the utility model patent with the authorization announcement number CN203745429U discloses a scanning device for ultrasonic testing that can achieve stable coupling. During ultrasonic flaw detection, the device uses the attraction of the magnet to the workpiece and the damping spring set on the rectangular bracket to make the probe run smoothly, reducing the deviation of the test result caused by human factors. When in use, the operator pushes the scanning device to move on the surface of the workpiece by hand, which is very practical. The scanning speed is improved and the production efficiency is significantly improved.

[0004] However, in actual use, ultrasonic probes of different specifications cannot be well fixed on the device, which reduces the application scope of the device and cannot well meet the use requirements. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figures 1 to 6 A small and portable ultrasonic scanning device comprises: a fixing seat 1 for installing an encoder 13, a connecting plate 2 for installing an ultrasonic probe 21, a connecting seat 11 is installed at the lower end of the fixing seat 1, a connecting roller 12 is rotatably installed at the end of the connecting seat 11, and the encoder 13 is installed on the connecting seat 11; a connecting mechanism 4 is arranged between the fixing seat 1 and the connecting plate 2, and is used to connect the fixing seat 1 and the connecting plate 2; a fixing mechanism 3 is installed on the connecting plate 2, and is used to fix the ultrasonic probe 21. In this embodiment, the encoder 13 and the ultrasonic probe 21 are both existing mature technologies.

[0024] As a further solution, the connecting mechanism 4 includes a connecting guide rail 51 installed on the right side of the fixed seat 1, and a connecting sleeve 5 is installed at the corresponding position on the left side of the connecting plate 2. The connecting sleeve 5 is slidably mounted on the connecting guide rail 51. A limit baffle 14 is also installed on the upper end of the fixed seat 1. By setting the limit baffle 14, the connection plate 2 can be effectively prevented from separating from the fixed seat 1. A pair of connecting rods 43 are also installed on the upper half of the fixed seat 1, and a pair of connecting rods 41 are installed on the lower half of the connecting plate 2. A connecting spring 42 is fixed between the connecting rods 41 and 43.

[0025] By providing the connection mechanism 4, the height of the connection plate 2 can be adjusted, thereby achieving the height adjustment of the ultrasonic probe 21. During scanning, the ultrasonic probe 21 can be coupled with the detection workpiece to improve the detection effect.

[0026] As a further solution, the fixing mechanism 3 includes a pair of fixing frames 31, each of which has a fixing groove 1 32 on the left side, a fixing groove 2 33 at the corresponding position of the connecting plate 2, a fixing bolt 1 34 installed at the corresponding position of the fixing groove 1 32 and the fixing groove 2 33, an ultrasonic probe 21 inserted between the pair of fixing frames 31, the ultrasonic probe 21 and the fixing frame 31 are fixedly connected by a fixing bolt 2 35, and the pair of fixing frames 31 are fixedly connected by a fixing bolt 3 36. In this embodiment, the fixing groove 1 32 is a horizontally arranged strip groove, and the fixing groove 2 33 is a vertically arranged strip groove. By setting the horizontally arranged fixing groove 1 32, the forward and backward movement of the fixing frame 31 is facilitated, thereby facilitating the installation of ultrasonic probes 21 of different specifications.

[0027] The working principle of the fixing mechanism 3 is: first, loosen the fixing bolt 1 34, then the fixing frame 31 can be moved up and down to adjust the installation height of the ultrasonic probe 21, and the fixing frame 31 can be moved forward and backward to adjust the distance between the fixing frames 31, so as to facilitate the installation of ultrasonic probes of different specifications. After the position of the fixing frame 31 is adjusted, tighten the fixing bolt 1 34 to preliminarily fix the fixing frame 31, and then insert the ultrasonic probe 21 between a pair of fixing frames 31, and then fix the ultrasonic probe 21 to the fixing frame 31 through the fixing bolt 2 35, and then fix the pair of fixing frames 31 through the fixing bolt 3 36. Through the fixing mechanism 3, ultrasonic probes 21 of different specifications can be fixed, which is convenient for subsequent maintenance, improves the applicability of the device, and thus better meets the use requirements.

[0028] The working principle of the utility model is: when it is used specifically, first, the ultrasonic probe 21 is installed through the fixing mechanism 3, and then the device is placed on the workpiece to be detected, and then the fixing mechanism 3 is pressed to drive the ultrasonic probe 21 to move down and make it close to the workpiece to be detected. At this time, the connecting spring 42 is stretched, which can effectively prevent the connecting plate 2 from separating from the fixing seat 1. Then, the device is pushed to move, and the moving trajectory of the device can be monitored through the encoder 13. At the same time, the ultrasonic probe 21 detects the workpiece.
