Description

Technical Field

[0001] This utility model relates to the field of center positioning tooling technology, specifically to a center positioning tool for a pressure vessel processing device. Background Technology

[0002] Currently, the workshop typically uses a measurement method to center circular workpieces (such as reinforcing rings for pressure vessels). The specific process is as follows: the center of the circular workpiece is roughly placed on the infrared positioning of the flame cutting machine. Then, one end is fixed to the edge of the circular workpiece, and the other end is moved along the edge of the workpiece and the length is measured. After finding the diameter of the circular workpiece, it can be determined whether the infrared positioning of the flame cutting machine is located at the center of the circular workpiece. If the infrared positioning of the flame cutting machine is not located at the center of the circular workpiece, the circular workpiece needs to be repositioned and measured again. If the infrared positioning of the flame cutting machine is exactly located at the center of the circular workpiece, it is also necessary to measure and verify again from other angles to ensure that the center of the circular workpiece is found accurately.

[0003] This measurement method is very cumbersome to operate, wastes a lot of time, and has low positioning accuracy, which seriously affects production efficiency.

[0004] Therefore, developing and designing a center positioning tool that is easy to operate, accurate in positioning, and highly efficient in production is an urgent problem to be solved at this stage. Utility Model Content

Two clamping seats at both ends of the telescopic rod can clamp a circular workpiece in the middle. Two ranging components can measure the distance to a measuring point on the centering block in real time. By adjusting the clamping positions of the two clamping seats and ensuring the sum of the distances measured by the ranging components matches the diameter of the circular workpiece, the measuring point is guaranteed to be located on the diameter of the circular workpiece. Then, the centering block is moved along the axis of the telescopic rod until the distances measured by the two ranging components are equal. The position of this measuring point is the center origin of the circular workpiece. The tool is easy to operate, provides accurate positioning, and has high production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
