Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] The core of this application is to provide an auxiliary inspection device for non-destructive testing of profile cavities. This auxiliary inspection device can meet the inspection needs of different locations on the profile and effectively improve the accuracy of defect detection. Another core aspect of this application is to provide an inspection device that includes the aforementioned auxiliary inspection device for non-destructive testing of profile cavities.

[0035] This application provides an auxiliary testing device for non-destructive testing of cavities, including a testing positioning seat 1 and a non-destructive testing sensor; wherein, the external structure of the testing positioning seat 1 is a contour-following structure, used to fit and cooperate with the inner wall of the pipe to be tested, and to move along the length direction of the pipe to be tested; the testing positioning seat 1 has a plurality of positioning holes 111, and the non-destructive testing sensor can be selectively inserted into the corresponding positioning hole 111.

[0036] The detection positioning seat 1 adopts a contour-following structure, meaning that the shape of the detection positioning seat 1 is the same as the cross-sectional shape of the cavity of the target pipe to be tested, such as circular or square, and the outer surface dimensions of the detection positioning seat 1 are similar to the cavity dimensions of the target pipe to be tested, allowing for clearance fit or transition fit. This allows the detection positioning seat 1 to be inserted into the cavity of the pipe to be tested, and applying a pushing force to the detection positioning seat 1 will cause it to move along the length of the pipe. Preferably, the detection positioning seat 1 is made of 316 stainless steel.

[0037] refer to Figure 1 , Figure 3 , Figure 4 and Figure 7 As can be seen, a number of positioning holes 111 are provided on the detection positioning seat 1. The positioning holes 111 can be round holes or square holes, etc. It should be noted that there is no restriction on the arrangement of the positioning holes 111. For example, the number of positioning holes 111 can be arranged around the circumference of the detection positioning seat 1, or the number of positioning holes 111 can be arranged on the same side of the detection positioning seat 1 and along the width direction of the detection positioning seat 1, etc., as long as the defect detection requirements of the profile can be met.

[0038] It is equipped with a non-destructive testing sensor, which can be fitted with the positioning hole 111 with a gap or transition, so that it can be selectively inserted into the corresponding positioning hole 111. After the detection positioning seat 1 is inserted into the cavity of the profile, the defect detection of the inner wall of the profile can be completed by the non-destructive testing sensor. It should be noted that there is no restriction on the type of non-destructive testing sensor, as long as it can meet the defect detection requirements, such as magnetic leakage sensor, ultrasonic sensor or vision sensor, etc.

[0039] In summary, by setting several positioning holes 111 at different positions, the inspection requirements of different positions of the profile can be met. In addition, the conformal shape of the inspection positioning seat 1 effectively improves the positional accuracy of the non-destructive testing sensor, thereby improving the precision of defect detection.

The width direction of the detection positioning seat 1 is perpendicular to its length direction, and adjacent positioning holes 111 are connected. That is to say, a number of connected positioning holes 111 are combined to form a multi-level stepped hole. In other words, the multi-level stepped hole is a channel formed by two opposing wavy surfaces or toothed surfaces, etc., and each section of the multi-level stepped hole is a positioning hole 111.

The positioning hole 111, the accommodating cavity 112 and the wiring port 113 are connected in sequence. The tail end of the non-destructive testing sensor is inserted into the positioning hole 111 from top to bottom, and the cable connected to the tail end of the non-destructive testing sensor is inserted into the accommodating cavity 112 and extends through the wiring port 113 to the outside of the auxiliary detection device so that it can be connected to a data analysis device for processing signals via a cable.

[0044] Based on the above embodiment, the end of the detection positioning seat 1 is fixedly connected to the handle 2 for the inspection personnel to hold and push the detection positioning seat 1 to move along the length of the pipe, thereby extending the stroke of non-destructive testing.

[0045] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As can be seen, a handle 2 is fixedly connected to the right end of the detection positioning seat 1 by welding or riveting. Furthermore, the outer surface of the handle 2 has an anti-corrosion coating.

[0046] Based on the above embodiment, the handle 2 is provided with a mark 21 to indicate the position of the non-destructive testing sensor, so as to determine the depth position of the non-destructive testing sensor in the cavity inside the part to be tested.

[0047] Participate Figure 1 As can be seen, the mark 21 includes several scales, and the scales are evenly arranged along the length of the handle 2. Alternatively, the mark 21 includes several dots or straight lines, etc., and the marks are arranged in different levels at different length positions of the handle 2. Of course, the mark 21 is not limited to the above examples, as long as it can meet the requirements of positioning the non-destructive testing sensor.

One threaded hole can be used as a regular hole and the other threaded hole can be used as a spare hole to extend the service life of the auxiliary testing device.

[0052] Furthermore, the top surface of the base plate 12 is a surface treated with 1000-grit sandpaper, and the bottom surface is a surface treated with 600-grit sandpaper.

When the detection positioning seat 1 needs to be assembled, the base plate 12 is first placed in the corresponding position of the positioning cover 11. At this time, the center line of the mounting through hole 121 coincides with the center line of the threaded connection hole 116. Then, the threaded fastener 3 is passed through the mounting through hole 121 and screwed into the threaded connection hole 116 so as to adjust the non-destructive testing sensor during the use of the auxiliary detection device.

[0055] Preferably, in some specific embodiments, the wiring port 113 and the first threaded hole 114 are both opened on the left end wall of the detection positioning seat 1, the positioning hole 111 is opened on the top wall of the detection positioning seat 1, and the second threaded hole 115 is opened on the right end wall of the detection positioning seat 1.
