[0002] The cylinder sleeve is a key component in mechanical equipment such as engines, and its quality directly affects the performance and service life of the equipment. The surface quality of the inner wall of the cylinder sleeve is particularly important. It needs to have high precision, high smoothness and good wear resistance to ensure that the piston can move smoothly therein, reduce friction loss and improve mechanical efficiency. Therefore, a cylinder sleeve inner wall grinding device came into being. The existing cylinder sleeve inner wall grinding device is usually composed of a grinding part and a drive motor and other structures. When in use, the grinding part is fixedly installed on the output shaft of the drive motor, and then the grinding part is placed on the inner wall of the cylinder sleeve. The drive motor is started to drive the grinding part to rotate on its inner wall. At this time, the staff needs to hold the device and make reciprocating motion to make the inner wall of the cylinder sleeve evenly polished. However, this operation method greatly increases the workload of the staff to a certain extent, thereby reducing the working efficiency of the grinding device. In order to solve the shortcomings of the existing technology, we propose a cylinder sleeve inner wall grinding device. Utility Model Content
