[0002] Welding is commonly used to connect metal plate structures, and full penetration welding is generally used for some important welds. Quality inspection after welding is also very important.

[0003] In the existing detection device, such as Chinese patent application CN117091483A, by utilizing the coordinated arrangement of the displacement component, the support frame and the clamping component, the cylinder in the clamping component is used to adjust the position of the push-pull seat, and the connecting frame, the movable seat and the clamping seat are driven to move, so as to fix the plate body and ensure the stability of the plate body during detection. The first motor in the displacement component is used to drive the gear to rotate, and the U-shaped movable frame, the support frame and the plate body are driven to move through the meshing action of the gear and the tooth groove, so as to realize the plate movable welding deformation detection performance; by utilizing the coordinated arrangement of the intermittent displacement mechanism, the top frame, the lifting component and the test component, the height of the lifting seat and the test component is lowered by the electric push rod in the lifting component, so that The ball contacts the top surface of the plate body, and the displacement assembly is used to drive the plate body to move on the bottom surface of the ball. The second motor in the intermittent displacement mechanism drives the dial, the driving pin and the locking arc plate to rotate, driving the groove wheel to form an intermittent rotation of ninety degrees, driving the threaded rod to rotate, and changing the position of the gate seat and the test assembly at equal intervals in turn.
