Technical Field

[0001] This utility model relates to the technical field of casting inspection devices, specifically a rapid detection device for multi-angle casting porosity based on X-rays. Background Technology

[0002] The principle of X-ray inspection of castings: X-rays are emitted from an X-ray tube and penetrate the sample. Depending on the location of the defect in the sample, the X-ray source and the flat panel detector perform X-ray inspection from different dimensions, ultimately revealing all defects.

[0003] For example, the announcement number CN208654067U is titled "An X-ray Inspection Device for Casting Defects." This device includes an isolation chamber, a workbench, a robot controller, an inlet conveyor belt, an outlet conveyor belt, and an automatic sorting and picking machine. The isolation chamber is equipped with an isolation door, an inlet door, an outlet door, a robot, and an X-ray receiving plate. The inlet conveyor belt is located outside the inlet door, and a delivery conveyor belt is located inside the inlet door. A model identifier is located on one side of the delivery conveyor belt. The end of the delivery conveyor belt is equipped with two inlet doors. The outlet conveyor belt is located outside the outlet door, and an outgoing conveyor belt is located inside the outlet door. A labeling machine is located on one side of the outgoing conveyor belt.

[0004] The aforementioned device does not scan the casting comprehensively during use. If the casting needs to be flipped over, it must be disassembled and reinstalled, which increases the number of process steps and reduces the efficiency of casting inspection. Therefore, we proposed a multi-angle rapid detection device for casting porosity based on X-rays to solve the problems mentioned above. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model uses a hydraulic cylinder to drive the clamping plate to approach the casting and clamps and fixes the casting with two clamping plates. The clamping plate is rotated by the first rotary motor, which in turn drives the casting to rotate synchronously. The third threaded rod is rotated by the first drive motor, which allows the third nut seat to move along the outer wall of the third threaded rod, thereby adjusting the height of the casting. This facilitates the rotation operation of castings of different sizes and solves the problem that the existing X-ray inspection device for castings does not scan the casting comprehensively during use. If the casting is to be flipped, it needs to be removed and reinstalled, which increases the number of process steps and reduces the inspection efficiency of the casting.

[0015] (2) Through the transmission connection between the sprocket and the chain, the sliding block inside the electric guide rail at both ends can be moved by the second drive motor, which facilitates the movement of the first crossbeam in the X-axis direction. Through the connecting action of the connecting plate, the second crossbeam can be controlled to move synchronously with the first crossbeam, which facilitates the position adjustment of the X-ray receiving plate and the X-ray emitter in the X-axis direction.

[0016] (3) The rotating rod is driven to rotate by the second rotary motor, which can make the first gear and the third gear rotate synchronously. Through the meshing connection of the first gear and the second gear, and the meshing connection of the third gear and the fourth gear, the first threaded rod and the second threaded rod can be driven to rotate synchronously, thereby driving the first nut seat and the second nut seat to move synchronously. This facilitates the position adjustment of the X-ray receiving plate and the X-ray emitter in the Y-axis direction, while ensuring that the X-ray receiving plate and the X-ray emitter are on the same vertical line, which is convenient for detecting the porosity of the casting by X-ray.

The combined action of the T-shaped slide groove 25 and the I-shaped slider 26 can also improve the accuracy of the second crossbeam 27 during sliding, thus facilitating the precise positioning of the X-ray emitter 33 and the precise scanning of the casting.

[0025] Please see Figure 1 The protective box 1 has two hinges at the rear end, which connect to the protective box door 35. The protective box door 35 has handles 36 installed on both sides of its outer wall. The protective box door 35 has an observation window 37 installed inside. After the casting is placed inside the protective box 1, the protective box 1 can be sealed by closing the protective box door 35, ensuring that X-ray leakage is completely blocked when closed. The handles 36 make it easy for the operator to manually open and close the protective box door 35, ensuring that the operator can easily open and close it. The observation window 37 is made of transparent glass, which allows the operator to directly observe the inspection process while shielding the radiation, and to confirm the casting positioning, scanning status or abnormal conditions.
