DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figures 2 to 4 , the utility model provides an embodiment: a pinhole defect detection device for welding surface quality, including a shell 1, which serves as the main structural shell of the device, providing support and protection for internal components, the fixing effect of the connecting block 2 in the limit groove enables the reset spring 1 5 to be reliably connected to it, and the left side of the reset spring 1 5 is fixedly connected to the connecting block 2, which plays a role in providing restoring force, and the left side of the reset spring 1 5 is fixedly connected to the connecting block 1 6, and the reset spring 1 5 has an elastic effect, providing elastic support for its connecting block 1 6, the inner wall of the shell 1 is fixedly connected to the rotating rod 8, the shell 1 provides support for the rotating rod 8, and the rotating rod 8 is rotatably connected to the outside of the rotating rod 8 with a connecting rod 1 9, allowing rotation within a certain range, and the front side of the connecting rod 1 9 is fixedly connected to a reset spring 3, so that the reset spring 3 is reset after rotation, and the front side of the shell 1 is fixedly connected to two hinges 4, so that it can be better disassembled during maintenance, and the right side of the maintenance door 3 is fixedly connected to the limiting block 7, which can enable the maintenance door 3 to be quickly opened and closed.

[0034] Reference Figure 5 and Figure 6, the sealing strip 10 is used to fit tightly in the sealing groove 2. When squeezed by the maintenance door 3, the sealing strip 10 is deformed to form an effective sealing interface. A sealing groove 3 is opened inside the shell 1 to further enhance the sealing performance of the equipment. Usually, the design of multiple return springs 2 14 can evenly distribute the pressure applied to the sealing block 13 to enhance its sealing effect. The front side of the sealing block 15 is fixedly connected with a sealing strip 2 12. The design purpose of the sealing block is to provide a stable mounting base for the sealing strip 2 12 to ensure that it can effectively play a sealing role during operation. The design of the sealing strip 2 12 is similar to that of the sealing strip 1 and is usually used on the other side of the equipment to enhance the overall sealing performance. The right side of the shell 1 is fixedly connected with a convex plate 11, which squeezes the sealing strip 2 12.

[0035] Reference Figure 1 and Figure 2 The function of the sealing strip 12 is to reduce the radiation leakage generated inside the machine. The design of the sealing groove 2 ensures that the sealing strip can be effectively fixed and provides a good sealing effect, thereby increasing the service life of the equipment. The maintenance door 3 provides access to internal components for easy maintenance and overhaul. The function of the limit block 7 is to control the moving range of the maintenance door. The control button 16 is used to facilitate the switching of the machine. The fixed groove design of the limit block 7 allows the connecting rod 9 to slide stably and be fixed in a predetermined position. The control button 16 rotates the connecting rod 9 through the connecting rod 2, retracting the limit block 7 and pulling back the connecting rod 9 through the reset spring 2 14. The rotating base 17 connected to the inner wall of the cavity allows the robotic arm 18 to move flexibly in the cavity to adapt to different work requirements. The X-ray head 19 is fixedly connected to the robotic arm 18 and can be adjusted in angle. The base 20 is where the welding plate is placed.

[0036] Working principle: When in use, the maintenance door 3 is pushed by the handle 2, and the inner wall of the maintenance door 3 squeezes the sealing strip 10 inside the sealing groove 2, causing the sealing strip 10 to deform, thereby achieving a sealing effect. The convex plate 11 on the right side of the maintenance door 3 squeezes the sealing strip 12 inside the sealing groove 13, and the sealing strip 12 squeezes the multiple reset springs 14 on the rear side through the sealing block 15. The rebound force of the reset spring 14 puts it in a fitting state, thereby achieving a sealing effect, thereby ensuring the safety of the operator and avoiding the risk of radiation exposure. It also improves the stability and reliability of the equipment, extends its service life, and ensures the accuracy of the test results.

[0037] By pressing the control button 16, connecting rod 2 is driven, and connecting rod 2 drives connecting rod 1 9 to move. Connecting rod 1 9 is rotated by rotating rod 9, and connecting rod 1 9 is moved out of the fixed groove inside the limit block 7. Connecting rod 1 9 is reset by the reset spring 3 on the front side, and the maintenance door 3 is pulled open by the handle 2. Conversely, the maintenance door 3 is pushed with the handle 2 so that the fixed groove inside the limit block 7 is stuck on the top of connecting rod 1 9, thereby completing the effect of quick disassembly and opening, thereby realizing a simplified disassembly and installation process, which can shorten the time for equipment maintenance and inspection, thereby reducing production downtime and improving overall production efficiency. The design of quick disassembly and opening allows operators to quickly inspect and repair the equipment when problems occur, reducing the impact of failures on production.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
