Description

Technical Field

[0001] This utility model relates to the field of function adjustment of X-ray inspection mechanisms for small aircraft parts, specifically an electrically controlled X-ray inspection function adjustment device for small aircraft parts. Background Technology

[0002] Small parts for aircraft equipment repair are characterized by a wide variety but small quantity. For example, there are hundreds of types of aircraft hydraulic conduits of various specifications, but only one or two pieces of each type may be available. Radiographic inspection is frequently required during the manufacturing and repair stages of these small parts. To accommodate radiographic inspection of various specifications of small parts, it is necessary to develop a highly adaptable radiographic inspection function adjustment device.

[0003] The split-type fixed X-ray inspection system used in the production site, housed in a fixed lead room, operates at a voltage of 320kV. This high voltage results in a significant weight for the X-ray system, as well as the high-voltage generator and cooler. The 320kV split-type fixed X-ray system weighs approximately 150kg and consists of separate dual-cable X-ray head units, positive and negative high-voltage generators, and a water-cooled cooler. The X-ray head units are connected to the positive and negative high-voltage generators via special high-voltage cables. The cooler continuously supplies flowing water to the X-ray head units to cool the high temperatures generated during operation. Due to their size and weight, split-type fixed X-ray systems are typically installed in a fixed location and remain stationary. The existing adjustment device for the split-type fixed X-ray system is a manually operated rocker arm fixture, introduced over a decade ago, which suffers from significant aging due to its long service life. Adjustments to the X-ray head unit's lifting, extension, direction, and angle all require manual on-site operation, resulting in repetitive processes, high operational intensity, and the inability to remotely control the system during operation. Summary of the Invention

[0004] To address the aforementioned problems, this utility model proposes an electrically controlled adjustment device for X-ray inspection of small aircraft parts.

[0005] An electrically controlled X-ray inspection function adjustment device for small aircraft parts includes a tooling base plate, several sets of rollers installed at four azimuth angles on the lower part of the tooling base plate, a profile stand and a high-voltage generator installed on the upper part of the tooling base plate, a cooler superimposed on the high-voltage generator, a lifting electric mechanism set on the profile stand, a lifting screw cooperating with the lifting electric mechanism, a lifting base set on the lifting screw, and a chain cooperating with the lifting base to achieve secondary protection.

[0006] A fixing rod is installed between the tooling base plate and the profile stand to enhance the overall stability and strength of the adjustment device.

[0007] The lifting electric mechanism controls the rotation of the lifting screw in both clockwise and counterclockwise directions to raise and lower the lifting base.

[0008] The beneficial effects of this utility model are: through the mechanical structure and functional design of the lifting, telescopic, and tilting mechanisms of the ray mechanism, which are electrically controlled by the lifting, telescopic, and tilting mechanisms, this utility model achieves convenient operation, on-site and remote electric control, high efficiency and low strength.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0015] like Figures 1 to 3 As shown, an electrically controlled X-ray inspection function adjustment device for small aircraft parts includes a tooling base plate 2, several sets of rollers 1 installed at four azimuth angles on the lower part of the tooling base plate 2, a profile stand 4 and a high-voltage generator 10 installed on the upper part of the tooling base plate 2, a cooler 12 superimposed on the high-voltage generator 10, a lifting electric mechanism 3 set on the profile stand 4, a lifting screw 5 cooperating with the lifting electric mechanism 3, a lifting base 6 set on the lifting screw 5, and a chain 15 cooperating with the lifting base 6 to achieve secondary protection.

[0016] The cooler 12 is stacked on top of the high-voltage generator 10, which increases the overall counterweight of the regulating device and saves the footprint of the entire device.

[0017] Roller 1 can drive the entire adjustment device to move within the lead exposure chamber. Once it reaches the predetermined position, roller 1 can be locked.

[0018] A fixing rod 11 is added between the tooling base plate 2 and the profile stand 4 to enhance the overall stability and strength of the adjustment device. The profile stand 4 and the high-voltage generator 10 are installed at both ends of the upper part of the tooling base plate 2, which can serve as a counterweight to maintain the safety, stability and reliability of the adjustment device during operation.

[0019] The lifting electric mechanism 3 controls the lifting screw 5 to rotate clockwise and counterclockwise to raise and lower the lifting base 6. The lifting range is 400mm-2000mm. It is equipped with a scale with a scale range of 400mm-2000mm and a scale resolution of 1mm, so as to adjust the precise size adjustment of the focal length during the X-ray detection process.

[0020] The chain 15 connects the profile frame 4 and the lifting base 6. During the lifting process of the lifting base 6, the chain 15 moves synchronously, providing secondary safety protection for the lifting base 6.

[0021] The lifting base 6 includes a telescopic electric mechanism 7, a telescopic rod 13 connected to the telescopic electric mechanism 7 for controlling horizontal extension and retraction, an electric swing mechanism 8 installed at the same end of the telescopic rod 13, a ray mechanism fixing mechanism 9, and an electric rotating mechanism 14, i.e. Figure 1 The right side of the profile stand 4 is relatively heavy, so the high voltage generator 10 and cooler 12 are installed on the left side of the profile stand 4 to achieve an overall counterweight effect, so that the weight is balanced on both sides, which helps to maintain the stability of the system.

[0022] This utility model achieves convenient operation, on-site and remote electric control, high efficiency and low strength through the mechanical structure and functional design of the lifting, telescopic and tilting box deflection mechanism of the electric control X-ray mechanism by the lifting electric mechanism 3, telescopic electric mechanism 7, electric tilting mechanism 8 and electric turning mechanism 14.

[0023] Depending on the part of the workpiece being inspected, the telescopic electric mechanism 7 controls the horizontal extension and retraction of the telescopic rod 13, with a telescopic stroke of 0-800mm. It is equipped with a scale with a range of 0-800mm and a scale resolution of 1mm, which facilitates the position adjustment of workpieces of different sizes.

[0024] The fixing mechanism 9 of the ray mechanism is composed of two hollow semi-circular interlocking clamping blocks, and the radius of the arc is slightly larger than the radius of the ray mechanism body.

[0025] The electric swing mechanism 8 consists of two sets of electric mechanisms and gears.

[0026] The electric angle mechanism 14 controls the fixed mechanism 9 of the ray mechanism to rotate within ±30° along the W2 axis. The angle mode is electric rotary reducer angle. The electric mechanism with a brake is selected to ensure that it can be self-locked at any position. The adjustment method is electric. The tooling has an angle indicator panel to meet the needs of different angle adjustments.

[0027] The aforementioned X-ray mechanism fixing mechanism 9 is controlled by gears to rotate within a 180° range around the W1 axis. It is equipped with an electric mechanism and a brake to ensure that it can be self-locked at any position. The adjustment method is electric. The fixture is equipped with an angle indicator to meet the requirements of radiography at different angles.

[0028] The electric cornering mechanism 14 is controlled by two electric mechanisms to control the low-speed rotational motion.

[0029] The aforementioned radiation mechanism fixing mechanism 9 is used to erect and fix the radiation mechanism. The contact parts with the radiation mechanism are protected by soft rubber pads to avoid hard contact between the two.

[0030] After assembly, the high-voltage generator 10, cooler 12, and accessories on the lifting base 6 achieve overall balance through their own weight. The tooling is equipped with two manual operators, one for operation in the lead room and the other for remote operation on the control panel, which minimizes the labor intensity of workers and ensures the overall safety and stability of the tooling. It allows operators to remotely adjust the direction of the X-ray mechanism, the distance between the X-ray mechanism and the object, the angle of the X-ray beam, and the extension amount according to the actual shape and size of the workpiece being inspected, both from the production site and the control room. The operation is simple and efficient, improving the efficiency of on-site layout and reducing the labor intensity of operators.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
