[0002] In the field of industrial non-destructive testing, radiographic testing technology is widely used because it can reveal the internal structure of materials non-destructively. Its core principle is that when X-rays penetrate the object being inspected, the attenuation is caused by differences in the internal structure, which in turn forms an image or signal reflecting the internal characteristics on the detector. However, in the process of using X-rays for non-destructive testing, fixtures are required to clamp or fix the workpiece.

[0003] A tooling for non-destructive testing (NDT) equipment, disclosed in patent publication number CN207866763U, is used to fix NDT test specimens. The tooling includes a rectangular frame with a base plate on its lower side. The base plate and the four side borders of the rectangular frame form a cavity in which the test specimen is placed. Each of the four side borders of the rectangular frame has at least one through-hole coplanar with the frame. The tooling also includes several bolts that pass through the bolt holes to fix the test specimen. This tooling for NDT equipment has the following advantages: it can be used for NDT of test specimens of different sizes; it fixes the position of the test specimen, improving accuracy during the NDT process; and the designed slide rail facilitates the operation of the encoder during NDT, improving imaging efficiency.

[0004] However, the above-mentioned device still has some shortcomings in actual use. When different positions of the test piece need to be tested, it needs to be manually flipped, which reduces the efficiency of overall non-destructive testing of the workpiece. Summary of the Invention

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] In the description of this utility model, it is necessary to understand that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "top", and "bottom" are all based on the orientation or positional relationship shown in the accompanying drawings. The purpose is only to facilitate the description of this utility model and simplify the description, and is not intended to indicate or imply that the indicated component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0018] like Figure 1-4 The present invention provides a fixture for non-destructive testing, comprising: a support platform 1; The support platform 1 is equipped with a workbench 2 at its upper end. The device uses the support platform 1 as the overall support base, and the workbench 2 at the upper end of the support platform 1 serves as a bearing platform. A drive frame 3 is fixedly connected to the upper end of the workbench 2. The drive frame 3 is a hollow rectangular structure. A drive component 4 is provided in the drive frame 3. The drive frame 3 provides a closed space for the drive component 4 to reduce external interference. The drive assembly 4 is the core component for adjusting the workpiece angle. The drive assembly 4 includes: a first rotating rod 41, which is a cylindrical structure. The lower end of the first rotating rod 41 is embedded in the upper end of the worktable 2. A bearing is provided between the first rotating rod 41 and the worktable 2 so that the first rotating rod 41 is rotatably connected to the worktable 2. A second rotating rod 44 is provided on one side of the first rotating rod 41. The upper end of the second rotating rod 44 extends out of the drive frame 3 and is rotatably connected to the drive frame 3. A crank handle 46 is provided at the upper end of the second rotating rod 44. The crank handle 46 is integral with the second rotating rod 44. A fixing bolt is provided on the crank handle 46, and the fixing bolt passes through the crank handle 46 and connects to the drive frame 3. The upper end of the first rotating rod 41 is fixed with a placement cylinder 42. An anti-slip pad 47 is fixedly connected to the bottom of the placement cylinder 42, and the anti-slip pad 47 is in close contact with the inner wall of the placement cylinder 42. The anti-slip pad 47 increases the friction between the workpiece and the placement cylinder 42, preventing axial or radial sliding of the workpiece during rotation or inspection. The placement cylinder 42 is a hollow cylindrical structure. The top of the placement cylinder 42 passes through the drive frame 3. A bearing is provided between the placement cylinder 42 and the drive frame 3, allowing the placement cylinder 42 to rotate flexibly around its axis. A large toothed ring 43 is fitted onto the outer wall of the placement cylinder 42, and a small gear 45 is fitted onto the outer wall of the second rotating rod 44. The large toothed ring 43 meshes with the small gear 45. The rotational force of the crank handle 46 is transmitted to the placement cylinder 42 through gear transmission, so as to realize the slow and smooth rotation of the placement cylinder 42. This makes it easy to adjust the angle of the part of the workpiece to be inspected. When the angle is adjusted to the right position, the fixing bolt on the crank handle 46 can pass through the crank handle 46 to connect the drive frame 3, thereby locking the position of the crank handle 46 and preventing the placement cylinder 42 from rotating accidentally during the inspection process.

[0019] The drive frame 3 has a fixing component 5 on one side, which is responsible for the stable fixing of the workpiece. The fixing component 5 includes an L-shaped support column 51, which is located on the upper end of the worktable 2. An electric push rod 54 is fixed on the L-shaped support column 51. The output rod of the electric push rod 54 passes through the L-shaped support column 51. The L-shaped support column 51 provides rigid support for the electric push rod 54 to ensure stable transmission of its output force. The output end of the electric push rod 54 is connected to a rotating rod 52. A bearing is provided between the rotating rod 52 and the electric push rod 54 so that the rotating rod 52 can rotate synchronously with the placement cylinder 42. A rubber pad 53 is provided on the bottom surface of the rotating rod 52. The rubber pad 53 can not only avoid damage to the workpiece caused by hard contact when pressing the workpiece, but also further enhance the fixing effect. The rotating rod 52, the electric push rod 54 and the placement cylinder 42 are coaxially arranged to ensure that the pressing force is applied along the axis of the workpiece and to prevent the workpiece from shifting due to force and affecting the detection accuracy.

[0020] The drive frame 3 has a control panel 6 on one side, which is embedded in the drive frame 3. The control panel 6 is communicatively connected to the electric push rod 54. The operator can precisely control the extension and retraction of the electric push rod 54 through the control panel 6 to adjust the clamping force on the workpiece. This ensures that the workpiece is firmly fixed and avoids excessive clamping that could cause workpiece deformation, thus improving the convenience and automation of operation.

[0021] The following is a detailed description of the actual working scenario of a fixed fixture used for non-destructive testing.

[0022] The fixture for non-destructive testing includes the following steps: Step S1: Vertically place the workpiece to be inspected into the placement cylinder 42, ensuring that the bottom end of the workpiece contacts the anti-slip pad 47 inside the placement cylinder 42. The anti-slip pad 47 increases friction, initially preventing the workpiece from sliding inside the placement cylinder 42 and ensuring stable placement of the workpiece. In step S2, the operator starts the electric push rod 54 through the control panel 6 on one side of the drive frame 3, controlling its output rod to extend downward, driving the rotating rod 52 to move downward synchronously. When the rubber pad 53 on the bottom surface of the rotating rod 52 contacts and presses the top of the workpiece appropriately, the operator stops the electric push rod 54 through the control panel 6. Step S3: If it is necessary to adjust the workpiece detection angle, loosen the fixing bolt on the crank handle 46 to separate it from the drive frame 3, manually turn the crank handle 46, the crank handle 46 drives the second rotating rod 44 to rotate, and the small gear 45 on its outer wall rotates synchronously. Through the meshing transmission with the large gear ring 43 on the outer wall of the placement cylinder 42, the placement cylinder 42 and the internal workpiece rotate slowly and smoothly around the axis. During the rotation, the rotating rod 52 rotates synchronously with the workpiece through the bearing between it and the electric push rod 54 to avoid generating torsional force on the workpiece. Step S4: When the workpiece is rotated to the required detection angle, stop rotating the crank handle 46, tighten the fixing bolt on the crank handle 46 so that it passes through the crank handle 46 and is connected and fixed to the drive frame 3, thereby locking the position of the crank handle 46, the second rotating rod 44 and the placement cylinder 42 to prevent the workpiece angle from shifting during the detection process. Step S5: After the workpiece is fixed and the angle is locked, the operator uses non-destructive testing equipment to inspect the workpiece. Step S6: If the detection angle needs to be changed, repeat steps 3-4; if the detection is completed, control the output rod of the electric push rod 54 to retract upward through the control panel 6, so that the rotating rod 52 can be disengaged from the top of the workpiece, and then the workpiece can be removed.

[0023] It is understood that the above-mentioned embodiments mentioned in this utility model can be combined with each other to form combined embodiments without violating the principle and logic. Due to space limitations, this utility model will not elaborate further.

[0024] Those skilled in the art will understand that, in the above-described method of the specific implementation, the order in which each step is written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

[0025] The present invention provides a fixed fixture for non-destructive testing. The support platform 1 provides a stable foundation for the entire fixture, and the worktable 2 serves as a load-bearing platform. The two work together to ensure the stability of the overall structure of the fixture, which can effectively avoid the impact of foundation shaking on the testing accuracy during the testing process and provide a reliable and stable support environment for non-destructive testing. A bearing is provided between the placement cylinder 42 and the drive frame 3, allowing the placement cylinder 42 to rotate flexibly. After the workpiece to be inspected is placed in the placement cylinder 42, the drive assembly 4 can drive the placement cylinder 42 to rotate, which can conveniently adjust the workpiece inspection angle without the need for manual handling of the workpiece, thus improving the convenience and comprehensiveness of multi-angle inspection and helping to improve inspection efficiency. In the fixing component 5, the L-shaped support column 51 provides stable support for the electric push rod 54. The electric push rod 54 can drive the rotating rod 52 to move up and down, realizing the rapid clamping and loosening of the workpiece in the placement cylinder 42. This electrically controlled fixing method, combined with the precise control of the electric push rod 54 by the control panel 6, can not only ensure the reliability of workpiece fixing and prevent workpiece displacement during testing, but also avoid workpiece damage caused by uneven manual fixing force. At the same time, it improves the convenience and automation of fixing operation, thereby achieving the goal of improving the overall quality and operational efficiency of non-destructive testing.
