[0002] In the fields of petrochemicals, marine engineering, etc., welding is a common connection process used to connect different plates, castings, forgings and other materials. The quality of welded joints directly affects the safety and reliability of engineering structures, so non-destructive testing of welds is required to ensure that the welding quality meets the design and specification requirements.

[0003] Traditional plate welding detection devices usually place the plates on the top of the workbench, and then use the detection device to directly scan the plates for detection. The traditional detection method also requires workers to adjust the position of the plates when testing the plates, which increases the workload of the workers and reduces work efficiency.

[0004] Therefore, those skilled in the art provide a positioning device for non-destructive testing of plate welding to solve the problems raised in the above background technology. Utility Model Content

[0012] Through the above technical solution, a pair of sliding blocks are installed inside the connecting block to stabilize the rise and fall of the clamping plate, so that the clamping plate can be used to stably clamp the plate.

[0013] Furthermore, one-way threaded rods are rotatably arranged inside the two connecting blocks;

[0014] Through the above technical solution, the one-way threaded rod can be used to control the rise and fall of the clamp, so that the one-way threaded rod can be used to control the clamp to clamp the plate.

[0015] Furthermore, a hood is fixedly arranged on the front end surface of the workbench, a motor is fixedly arranged on the inner bottom of the hood, and a bidirectional threaded rod is fixedly arranged on the output end of the motor;

[0016] Through the above technical solution, the motor is fixed and protected by a machine cover, and the bidirectional threaded rod is driven to rotate by the motor, so that the two mounting plates can be moved inward or outward at the same time.

[0017] Furthermore, a mounting frame is fixedly provided on the rear end surface of the workbench, and a detection sensor is fixedly provided on the bottom end of the mounting frame;

[0018] Through the above technical solution, the detection sensor can be fixed by using the mounting frame, and the welding part of the plate can be detected by using the detection sensor.

[0019] Furthermore, support legs are fixedly arranged at the four corners of the bottom end of the workbench, and a control panel is fixedly arranged on the front end surface of the workbench;

[0020] Through the above technical solution, the device can be supported by supporting legs, and the motor and other devices can be controlled by the control panel, which is convenient for staff to use.
