[0002] With the development of the times and technology, the maritime and river transportation industries have been rapidly improved at this stage. Among them, the most indispensable type of maritime and river transportation is ships, and ships need to be maintained before each launch. At the same time, they also need to be inspected after they go ashore to ensure the superiority of the ship's performance. The most important task in the ship repair process is shaft positioning. The shaft is the general term for the shaft, and even a slight misalignment of the shaft will have a very serious impact on the ship's accessories. Therefore, it is necessary to position the shaft on the ship. The shaft can continue to be used in the original position of the ship's accessories after being positioned by the shaft positioning device.

A clamping plate is installed on the end side wall of the drive motor, an infrared generator is installed on the left part of the base, and an infrared receiver is installed on the right part of the base. The utility model can achieve the purpose of changing the spacing between the clamping plates through the telescopic work of the micro hydraulic rod, that is, it can clamp shafts of different diameters; while the shaft rotates, the infrared generator will emit infrared rays and shoot to the infrared receiver on the opposite side, and the figure received by the infrared receiver should be a circle with the same outer diameter as the shaft, and if the received figure is not a circle or a deviation occurs, it is determined that the shaft is faulty.
