DETAILED DESCRIPTION

[0020] The following will describe in detail a positioning bracket for a non-destructive testing device provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative ways for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.

[0021] As Figure 1 - Figure 2 shown, an embodiment of the present utility model provides a positioning bracket for a non-destructive testing device, including a base 1, a rotating seat 4 rotatably connected to the top, wherein the rotating seat 4 is installed in an embedded manner on the top of the base 1, and a thrust ball bearing is provided at the bottom of the rotating seat 4 to reduce the rotation resistance. Two limit plates 5 distributed in a straight line are provided on the top of the base 1; a top plate 3 is fixedly connected above the base 1 through a side plate 2, and forms a U-shaped structure bracket in combination with the base 1 and the side plate 2. A U-shaped groove 6 is opened at one end of the top plate 3 away from the side plate 2; there are two clamping jaws 8, both of which are rotatably connected to the top of the top plate 3 through a rotating shaft 7 and are symmetrically distributed with respect to the symmetry line of the U-shaped groove 6. An arc-shaped groove 9 is provided on the clamping jaw 8, and the two arc-shaped grooves 9 are configured to cooperate with each other during work to form an annular clamping groove directly above the rotating seat 4; further includes a sub-cylinder 12, and two symmetrically distributed support feet 13 are provided at the bottom side of the sub-cylinder 12. The annular clamping groove is used to clamp the top cylinder body of the sub-cylinder 12.

[0022] By providing the rotating seat 4 to support one end of the sub-cylinder 12 and cooperating with the clamping of the two clamping jaws 8, a vertical fixing tooling for the sub-cylinder 12 is carried out. During work, the non-destructive testing component is located on one side of the device to scan and detect the welding points of the branch pipes on one side of the sub-cylinder 12. By loosening the clamping of the two clamping jaws 8 and driving the sub-cylinder 12 to rotate, at this time, the rotating seat 4 rotates synchronously, realizing the flipping of the sub-cylinder 12, and then clamping and fixing again through the clamping jaws 8, so that the non-destructive testing component scans and detects the welding points of the branch pipes on the other side of the sub-cylinder 12. The operation is convenient and the positioning accuracy is high.

[0023] As Figure 2 shown, the two limit plates 5 are located on one side of the rotating seat 4 and are used to abut against the support feet 13.

[0024] During tooling, rotate the sub-cylinder 12 so that the support feet 13 abut against one of the limit plates 5, and when rotating and adjusting the sub-cylinder 12, make the support feet 13 abut against the other limit plate 5, then the 180° flipping of the sub-cylinder 12 can be realized, ensuring that the branch pipes on both sides of the sub-cylinder 12 face the detection component during detection and improving the detection accuracy.

[0025] As Figure 1 shown, the opening of the U-shaped groove 6 faces away from the side plate 2.

[0026] This arrangement makes it easy to slide the air cylinder 12 directly through the opening of the U-shaped groove 6 when carrying and clamping it, thereby playing a certain auxiliary supporting role, preventing the air cylinder 12 from tipping over, and will not be blocked by the side plate 2, thus facilitating tooling.

[0027] like Figure 1 As shown, a locking hook 10 is provided on the top of one of the top plates 3 , and a locking rod 11 is provided on the top of the other top plate 3 . The locking hook 10 and the locking rod 11 are configured to cooperate with each other during operation to limit the rotation of the two clamping jaws 8 .

[0028] Through the cooperation and clamping of the locking hook 10 and the locking rod 11, when the two clamping jaws 8 are close to each other to clamp the sub-cylinder 12, the two clamping jaws 8 are locked at one end away from the rotating shaft 7 to clamp and fix the sub-cylinder 12 to prevent it from rotating during the detection process and causing detection errors.

[0029] Rubber pads are provided on the top of the rotating seat 4 and the inner wall of the arc-shaped groove 9.

[0030] Through this arrangement, when the sub-cylinder 12 is tooled, damage to its outer wall due to rigid contact friction is avoided, while the friction resistance to it is increased, thereby improving the fixing effect.

[0031] The technical solution provided by the utility model is in actual use. In the initial state, the two clamping claws 8 at the top of the top plate 3 are in an open state (refer to Figure 1 ), move the air cylinder 12 to the top of the rotating seat 4, and at the same time, the top area of ​​the air cylinder 12 slides into the U-shaped groove 6. As the tank slides in, the contact claws 8 protrude from the side wall of the U-shaped groove 6, and as the cylinder body is pushed forward, the two claws 8 are driven to close to each other. After the air cylinder 12 is completely inserted into the U-shaped groove 6, the air cylinder 12 is rotated so that the support feet 13 at the bottom thereof abut against one of the limit plates 5, which assists in pressing the two claws 8, and the lock hook 10 hooks the lock rod 11 to complete the positioning tooling (refer to Figure 2 ), after the detection is completed, disconnect the connection between the lock hook 10 and the lock rod 11, rotate the sub-cylinder 12, so that the support foot 13 at the bottom thereof abuts against another limit plate 5, and is locked again, thereby completing the flipping and positioning tooling of the sub-cylinder 12. During disassembly, disconnect the lock of the lock hook 10 and the lock rod 11, and directly remove the sub-cylinder 12. As the sub-cylinder 12 moves outward, the two clamping jaws 8 are driven to rotate to both sides. As the sub-cylinder 12 moves out of the U-shaped groove 6, the two clamping jaws 8 are automatically reset to the initial position to facilitate subsequent tooling fixation.

[0032] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
