[0002] At present, bearings are components that fix and reduce the load friction coefficient in the process of mechanical transmission. They are used to reduce the friction coefficient in the process of power transmission and keep the center position of the shaft fixed. When the bearings are in use, the smoothness of the bearing surface itself has a huge impact on the performance of the bearings. Therefore, during the production process of the bearings, the surfaces of each component need to be finely ground many times to ensure the transmission efficiency of the bearings during movement.

[0003] A large-circle grinding device is disclosed in a Chinese utility model patent with the announcement number CN211332616U. The large-circle grinding device includes a bottom plate; two side plates, both of which are fixedly mounted on the top of the bottom plate; a top plate, which is fixedly mounted on the tops of the two side plates; a first cylinder, which is fixedly mounted on the bottom of the top plate; an upper clamping plate, which is rotatably mounted on a support column on the output rod of the first cylinder, which is rotatably mounted on the bottom plate, and which is located between the two side plates; a lower clamping plate, which is fixedly mounted on the top of the support column; a first pulley, which is fixedly sleeved on the support column; and a first motor, which is fixedly mounted on the top of the bottom plate.

In addition, it is difficult to grind the inner surface, and it is inconvenient to insert the grinding head. The large grinding head that is easy to insert will produce a gap with the inner surface of the ring, thereby reducing the grinding effect. Utility Model Content

[0011] As a further improvement of the above solution, a guide rail for the movable block to slide is arranged inside the base, and a first sliding groove for the clamping plate to slide is opened on the upper surface of the base.

[0012] Through the above technical solution, the setting of the guide rail plays a limiting role on the movable block and improves the stability of the splint at the same time.

[0018] The utility model controls the air cylinder to drive the grinding head to enter the interior of the circular ring, and inflates the airbag through an electric micro air pump, so that the airbag expands and pushes out the cross bar, thereby making the grinding head stick to the inner surface of the circular ring, and controlling the grinding motor to rotate, thereby driving the grinding head to rotate through the grinding disk to grind the inner surface of the circular ring.
