[0034] like Figure 6 As shown, in order to clamp a missile with a smaller diameter, the length of the support block is longer, and a reinforcing block 14-10 is provided on the top of the support block. The top of the reinforcing block 14-10 is arc-shaped, and the tops of several reinforcing blocks are surrounded to form a circumference. For a support block with a longer length, the reinforcing block can increase the contact area between the support block and the missile being tested, so that the two are fixed more firmly.

[0035] When the fixture is in use, first insert the support block into the block fixing groove, clamp the missile 32 to be tested with the upper support ring and the lower support ring, make the support block in close contact with the missile to be tested, reduce the weight of the overall fixture by the weight-reducing hole, align the upper support ring with the lower support ring, ensure that the left and right screw grooves of the upper support ring and the left and right screw holes of the lower support ring are aligned; in order to make it easier to align, mutually matching aligning grooves 14-11 and aligning bosses 14-12 can be provided at the aligning parts of the upper support ring and the lower support ring, which is more convenient for positioning; insert two fixing screws into the two screw grooves respectively and tighten them, so as to achieve a firm clamping of the missile to be tested; according to the length of the missile 32 to be tested, two fixtures can be provided at appropriate positions at both ends.

The center of the ray emission port of the X-ray source is directly opposite to the center of the digital imager, and is at the same horizontal height as the center of the fixture, that is, the axis of the missile under test, so as to ensure that the ray fully covers the missile under test and fully utilizes the digital imager; the electrical adapter box is installed inside the main bracket to improve the compactness of the system.

[0039] like Figure 3 As shown, the control and acquisition circuit of the present invention is composed of an electrical adapter box, a control box, a radiation source controller, an alarm, a mobile power supply, a mobile cable reel and a computer; the connection relationship between the circuits is: the control box is connected to the electrical adapter box through a 50-meter control cable to send control instructions, and is connected to the camera through a 50-meter video cable to receive video monitoring information; the radiation source controller is connected to the X-ray source through a 50-meter radiation control cable to control it, and is connected to the alarm to send an alarm signal; the computer is connected to the digital imager through a 50-meter network cable to collect radiation image information; the mobile power supply supplies power to the control box, the radiation source controller and the computer respectively through the mobile cable reel, and supplies power to the electrical adapter box; the electrical adapter box supplies power to the camera, the digital imager, the load-bearing slide motor, the roller motor and the imager motor respectively, and controls the actions of the above three motors.

[0040] The present invention sends control instructions to the electrical adapter box through the control box, thereby driving the corresponding motor to move, and realizing 360-degree scanning of the entire missile from head to tail by X-ray. The display on the control box receives the live video from the camera in real time, thereby realizing real-time monitoring of the site. The computer receives the ray image signal from the digital imager in real time, and after image processing, it is provided to the user for viewing for fault identification. The radiation intensity of the X-ray source is adjusted by the ray source controller, and the appropriate radiation intensity can be set for different positions of the missile under test until the best image is obtained. After replacing the missile under test with different diameters, the position of the digital imager should be adjusted through the control box to adjust the focal length, and the appropriate focal length can be set by observing the image clarity on the computer.
