Example Embodiment

[0011] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as figure 1 , figure 2 As shown, the rotating steel ring welding detection device of this embodiment includes a rotating support base 10 and arc-shaped guide detection devices symmetrically located on both sides of the rotating support base 10; the rotating support base 10 includes a clamping base 101 and a rotating cylinder 102 , The clamping seat 101 is equipped with a steel ring 1 through the clamping rod 103, and the steel ring 1 swings 180 degrees between two arc-shaped guide detection devices through the rotating support seat 10; the arc-shaped guide detection device includes an arc guide device and a welding Seam detection head 9, a welding seam detection head 9 is slidably installed in the arc guide device, the ultrasonic detection end 901 at the inner end of the weld seam detection head 9 faces the center of the arc guide device; the arc guide device includes an inner arc guide plate set inside and outside 2 and the outer arc-shaped drive plate 3, the inner arc-shaped guide plate 2 is provided with arc-shaped guide grooves 201, both ends of the outer arc-shaped drive plate 3 are installed with a rack 5 through the end gear 4, and the end gear 4 passes through the bracket 6 is connected with the inner arc guide plate 2; a guide gear 7 and a guide shaft 8 are installed at the outer end of the weld inspection head 9. The guide gear 7 meshes with the rack 5, and the guide shaft 8 is fitted in the arc guide groove 201.
[0013] When in use, the rotating cylinder 102 drives the clamping base 101 to rotate, turning the steel ring 1 into the arc guiding device of the arc guiding detection device on one side; the end gear 4 on the driving side (the drive motor is not shown), The rack 5 moves along the outer arc-shaped drive plate 3, thereby driving the weld inspection head 9 to move on the inner arc-shaped guide plate 2, so as to perform ultrasonic inspection on the lower half of the steel ring 1; the rotating cylinder 102 drives the steel ring 1 Swing 180 to the arc-shaped guide on the other side to perform ultrasonic inspection of the other half of the steel ring 1.
[0014] The above-mentioned embodiments are the preferred embodiments of the present invention. They are only used to facilitate the description of the present invention, and are not intended to limit the present invention in any form. Anyone with ordinary knowledge in the technical field, if they do not deviate from the provisions of the present invention Within the scope of the technical features, the equivalent embodiments with partial changes or modifications made using the technical content disclosed in the present invention without departing from the technical features of the present invention still fall within the scope of the technical features of the present invention.
