Description
Technical Field
[0001] The utility model relates to the technical field of steel pipe grinding devices, and particularly relates to an end grinding device for cutting steel pipes. Background Technique
[0002] According to actual usage requirements, steel pipes often need to be cut. After cutting, the edge of the section is usually relatively sharp and burrs remain. Therefore, it is easy to cut the fingers and palms when workers carry and pick up the steel pipes. Thus, after the steel pipe is cut, the edge of the section needs to be ground. For circular steel pipes, when grinding, the steel pipe needs to be clamped and fixed and centered first. Generally, the centering fixture is usually composed of three cylinders with an included angle of 120° between every two of them. To achieve centering, the telescopic rods of the three cylinders need to extend synchronously. However, to control the synchronous operation of the three different cylinders, a synchronous control system needs to be used, which will increase the cost of the device. Content of the Utility Model
