[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0026] Example

[0027] In order to solve the problem that the flaw detection equipment in the prior art will increase the labor intensity of operators and have low work efficiency when performing flaw detection on medium and large hollow castings, reference Figure 1 and Figure 2 As shown, the present application discloses a rotary flaw detection device, comprising: a machine table 10;

[0028] An annular guide rail 20, the annular guide rail is arranged above the machine platform;

[0029] An annular hollow slide plate 30, the annular hollow slide plate is slidably connected to the upper part of the annular guide rail, and an annular rack 311 is provided on the inner ring of the annular hollow slide plate;

[0030] An X-ray searchlight 40, which is disposed above the annular hollow slide and emits X-rays toward the hollow portion of the annular hollow slide;

[0031] An inner support fixture 50, which is fixed above the machine platform at the hollow portion of the annular hollow slide;

[0032] The output end of the rotary driving part 60 passes through the machine platform and is provided with a gear 70 which is meshed and connected with the annular rack.

[0033] During specific use, the operator first places the medium and large castings to be inspected on the machine table and clamps them with the internal support clamps. Then, the X-ray searchlight is started to emit X-rays and the rotating drive unit is controlled to drive the annular hollow slide to rotate on the annular guide rail through the cooperation of gears and annular racks. During this process, the X-rays emitted by the X-ray searchlight will be located on the surface of the medium and large castings to detect flaws. After the X-ray searchlight rotates around the medium and large castings for one circle, the inspection is completed.

[0034] In addition, it should be noted that the flaw detection principle of the X-ray searchlight of the present application is a known technology and will not be elaborated on here.

[0035] refer to Figure 1As shown, the inner support clamp of the present application includes an annular hollow protrusion 51 and an airbag 52. The airbag is arranged inside the annular hollow protrusion. Through grooves 53 are arranged on the opposite sides of the annular hollow protrusion. Ejector brackets 54 are respectively arranged on the opposite sides of the airbag to pass through the through grooves. When clamping medium and large castings, the airbag is controlled to inflate. At this time, the ejector brackets on both sides will be pushed up so as to abut against the inner wall of the medium and large castings to achieve clamping. Otherwise, it will not be repeated.

[0036] Specifically, the ejection bracket of the present application is composed of a push rod 541 and a push block 542. The push rod passes through a through slot and is connected to the airbag. The push block is connected to the push rod outside the annular hollow protrusion, and the area of ​​the push block is larger than the area of ​​the through slot. After the airbag is inflated, the push rod will drive the push block to extend out and abut against the inner wall of medium and large castings. In addition, by setting the area of ​​the push block to be larger than the area of ​​the through slot, the push block can be prevented from entering the inside of the annular hollow protrusion.

[0037] In order to prevent medium and large castings from being blocked by the annular hollow slide, which would leave a blind spot for the X-ray searchlight, the present application provides an annular raising block 80 in the hollow portion of the annular hollow slide to be fixed to the machine platform, and an internal support clamp is provided on the upper surface of the annular raising block. In the specific setting, the upper surface of the annular raising block must at least be flush with the upper surface of the annular hollow slide.

[0038] In order to facilitate the connection of the airbag's air intake pipe and exhaust pipe to the airbag, the machine and the annular raising block of the present application are provided with a first through hole 11 and a second through hole 12 which are communicated with the interior of the annular hollow protrusion. The exhaust pipe of the airbag is arranged through the first through hole, and the air intake pipe of the airbag is arranged through the second through hole.

[0039] In some specific embodiments, the rotary drive unit includes a low-speed motor 61 and an encoder 62. The low-speed motor and the encoder are both arranged at the bottom of the machine, and the gear is installed on the output shaft of the encoder. With the cooperation of the low-speed motor and the encoder, the gear will rotate and cooperate with the annular rack to make the annular hollow slide slide on the annular guide rail. In addition, the encoder can calculate the number of revolutions of the low-speed motor, ensuring that the X-ray searchlight stops after rotating one circle around medium and large castings.

[0040] In addition to the above structure, the present application also includes a ball screw slide 90. A mounting groove 32 is provided on one side of the upper surface of the annular hollow slide. The ball screw slide is arranged in the mounting groove. The X-ray searchlight is installed on the slide of the ball screw slide. Driven by the ball searchlight, the X-ray searchlight can automatically adjust the distance from medium and large castings, so as to obtain the best flaw detection position, which has high practicality.

[0041] In the description of this specification, the description with reference to the terms "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0042] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable technicians familiar with the technical field to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.
