Figure 1-Figure 2 As shown, a pipe socket circumferential grinding device is proposed, including a grinding assembly and a base 1. The grinding assembly is rotatably arranged on the left side of the top end of the base 1. After the grinding assembly is rotated and adjusted, the pipe socket can be inclined and grooved. The grinding assembly includes a box body 2 installed on the left side of the upper surface of the base 1, and also includes a first rotating rod 3 rotatably connected to the right side of the inner cavity of the box body 2 through a bearing from front to back. The outer wall of the first rotating rod 3 is connected to one end of a connecting cantilever 12, and the other end of the connecting cantilever 12 is connected to the grinding assembly. When the connecting cantilever 12 rotates, it can drive the grinding assembly to rotate synchronously. The inner cavity of the box body 2 is rotatably connected to a second rotating rod 5 from front to back through a bearing. The outer wall of the second rotating rod 5 is installed with a second gear 6. The second gear 6 is meshed and connected with the outer wall of the first gear 4. When the second gear 6 rotates, it can drive the first gear 4 to rotate circumferentially, thereby driving the first rotating rod 3 connected to the first gear 4, the connecting cantilever 12 and the grinding assembly to rotate;

[0026] See also Figure 2 As shown, the second gear 6 is rotated circumferentially and locked by a driving component, which includes a limiting groove 7 opened on the left side of the inner wall of the box body 2 in the vertical direction, and also includes a lead screw 8 rotatably connected to the bottom end of the inner wall of the limiting groove 7 through a bearing, a hand wheel 10 is installed on the top of the lead screw 8, and the lead screw 8 extends upward from the outer wall of the box body 2, a lifting block 9 is threadedly sleeved on the outer wall of the lead screw 8, and the lifting block 9 is slidably embedded in the inner cavity of the limiting groove 7, a rack 11 is installed on the right side wall of the lifting block 9, and the outer wall of the rack 11 is meshed and connected with the outer wall of the second gear 6;

[0027] The specific steps for adjusting the inclination angle of the grinding assembly to perform socket grinding processing on the pipe with different inclined grooves are as follows: drive the handwheel 10 to drive the screw 8 to rotate, and then drive the lifting block 9 to move in the vertical direction along the inner cavity of the limit groove 7, so as to drive the rack 11 connected to the right side of the lifting block 9 to move synchronously in the vertical direction. At this time, the second gear 6 meshing with the outer wall of the rack 11 drives the second rotating rod 5 to rotate synchronously, and drives the first gear 4 meshing with the outer wall of the second gear 6 to rotate circumferentially. At this time, the first gear 4 drives the first rotating rod 3 and the connecting cantilever 12 to rotate synchronously, thereby realizing the inclination angle of the grinding assembly.
