The turntable of the model can be directly driven out of the lead room for loading and unloading, which is very convenient and easy to use for testing large castings. The small rotary table is used for the inspection of small castings. The four-axis gantry displacement system can realize the lifting, pitching, and front-rear movement of the ray machine and the imaging plate to adjust the focal length and the left and right traverse. The system adopts a directional camera, and the lifting becomes a full-body full-scale inspection of the casting with the rotation of the turret.

The ray machine and imaging plate positioner adopt four-axis gantry displacement system, which consists of four-column gantry, moving beam, ray machine front and rear drive module, ray machine lifting module, ray machine pitch module, imaging plate front and rear drive module, imaging plate lifting module , imaging board pitch module and other components.

The gantry is shown in the figure below.

The ray machine pitching mechanism adopts the connecting rod slider technology + penetration is the perfect combination technology of the screw linear servo drive, which solves the limitation of space and solves the problem that the conventional pitching driving technology is difficult to realize the maximum detection range.

The large-scale rotary table adopts the form of trolley, which facilitates the loading and unloading of large workpieces. The trolley adopts 8-wheel structure to achieve perfect direct ditch, without manual overlapping butt joints. The large and small table body is rotated by precision slewing bearing and servo motor drive, which ensures the smoothness of the product rotation and makes the imaging effect the best. The module design is shown in the figure below.

The system inspection process only requires the operator to complete in the operation room without entering the lead room operation. The operator only needs to input the specification model of the product to be inspected on the control interface. The product enters the detection area and rotates the product to the set posture according to the monitoring screen. As a detection starting point, the system automatically adjusts the spatial position of the ray machine and the imaging plate. The operator activates the fully automatic detection button with one button. The system will automatically check the automatic inspection program of the pre-tested storage according to the model of the product to be inspected, and complete the detection of the whole entity of the product step by step, which greatly improves the detection efficiency. The operator only needs to be responsible for real-time evaluation and supervision of the inspection process

Seven, summary:

The technical highlights are as follows:

1,It is a fully automatic dynamic and static detection system that is the most advanced and unique casting defect in the industry;

2,The clever driving structure technology of the lifting system;

3,Ingenious drive structure technology for ray machine pitching;

4, 8 rounds of trolley structure for barrier-free use, greatly solve the problem that the conventional 4-wheeled trolley can not pass the ditch;

5. During the whole process of testing, the displacement of testing equipment and products is more flexible, free, stable and reliable than the current technology.
