Grooved pipe fitting burr removing device

The utility model discloses a groove pipe fitting burr removing device which comprises a machine body, and the machine body is connected with a workbench and a grinding power head which can relativelyachieve longitudinal and transverse movement. A grinding wheel is installed on a power output shaft of the grinding power head and comprises a disc body and a sleeve body, one end of the sleeve bodyis fixedly connected to the disc body, and convex ribs are annularly arranged on the inner wall face of the sleeve body. And abrasive layers are arranged on the outer side surfaces, the inner side surfaces and the inner ring surfaces of the convex ribs. The device can be used for efficiently and conveniently grinding casting burrs; particularly, grinding can be carried out in a mode that the groove pipe fitting is internally tangent to a circle of grinding material layer on the inner ring surface of the convex rib; when burrs are ground off, obvious concave parts cannot be formed at the bottomof the groove and on the s
