Description

Technical Field

[0001] The utility model relates to the technical field of coating detection, in particular to a detection device with an adjustment mechanism. Background Art

[0002] The coating thickness gauge can non-destructively measure the thickness of non-magnetic coatings (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal substrates (such as steel, iron, alloys and hard magnetic steel, etc.) and the thickness of non-conductive coatings (such as enamel, rubber, paint, plastic, etc.) on non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.).

[0003] Coating thickness gauges can be used to detect the coating thickness inside small-diameter nickel-based alloy pipes. During the detection process, workers are required to hold the probe and extend it into the pipe, and fit it against the inner wall of the pipe for detection. In order to obtain more accurate test data, the probe needs to be moved against the inner wall of the pipe. However, most coating thickness gauge probes on the market lack positioning devices, and rely entirely on workers to manually move the probe to adjust the test position. The movement is not stable enough and easily affects the test value. Utility Model Content

By setting the positioning mechanism 4, the probe 2 can be positioned inside nickel-based alloy pipes of different pipe diameters, which can not only improve the detection accuracy of the probe 2, but also make it more convenient to use.

[0023] The positioning mechanism 4 includes a connecting seat 41, a threaded rod 42, a connecting rod 43, a positioning rod 44, a sleeve 45, a steel ball 46, a push block 47, and a rotating block 48; the connecting seat 41 is fixedly installed on the outer wall of the probe 2, the inner wall of the connecting seat 41 is hinged with a positioning rod 44, and the end of the positioning rod 44 away from the connecting seat 41 is fixedly installed with a sleeve 45, and the inner wall of the sleeve 45 is rollingly connected with a steel ball 46, and the steel ball 46 on the inner wall of the sleeve 45 is driven by the positioning rod 44 to fit the inner wall of the pipeline. At this time, the positioning rod 44 cooperates with the sleeve 45 and the steel ball 46, so that the probe 2 can be stably pressed against the inner wall of the pipeline, so that the probe 2 can move smoothly in the pipeline, and the threaded rod 42 is threadedly connected to the connecting seat The inner wall of the seat 41, and the threaded rod 42 passes through the connecting seat 41, one end of the threaded rod 42 is rotatably connected to the push block 47, and the other end of the threaded rod 42 is fixedly installed with a rotating block 48, the outer wall of the push block 47 fits the outer wall of the probe 2, and the threaded rod 42 is rotated by the rotating block 48. The rotation of the threaded rod 42 can drive the push block 47 to slide on the outer wall of the probe 2, one end of the connecting rod 43 is hinged to the side wall of the push block 47, and the other end of the connecting rod 43 is hinged to the side wall of the positioning rod 44, and moves to the end away from the connecting seat 41 through the push block 47. At this time, the push block 47 will push the connecting rod 43, so that the connecting rod 43 pushes the positioning rod 44, and the positioning rod 44 rotates to the end away from the probe 2.

[0024] The threaded rod 42 is provided with an auxiliary mechanism 5, which can facilitate the staff to insert the probe 2 deeper into the pipeline. The auxiliary mechanism 5 includes a threaded sleeve 51, a connecting rod 52, and a hollow rod 53; the threaded sleeve 51 is threadedly connected to the outer wall of the threaded rod 42, and the side wall of the threaded rod 42 is fixedly installed with the connecting rod 52, and the end of the connecting rod 52 away from the threaded sleeve 51 is fixedly installed with the hollow rod 53.
