Description

Technical Field

[0001] The utility model relates to the technical field of grinder structures, in particular to a CNC cylindrical grinder structure which is easy to maintain. Background Art

[0002] Cylindrical grinding machines are used to process the outer surfaces of cylindrical, conical or other shaped workpieces and the shoulder end faces. They are the most widely used grinding machines and can process various cylindrical and conical outer surfaces and shoulder end faces.

[0003] The Chinese utility model with authorization announcement number CN220613585U discloses a grinding wheel assembly structure for a CNC external cylindrical grinder. When the device is in use, the rotation of the threaded rod drives the limit fixing component and the limit mechanism to disengage from the fixing groove and the positioning mechanism, so that the grinding wheel body can be quickly disassembled. Conversely, the grinding wheel body can be quickly installed through the forward rotation of the servo motor. The goal of facilitating the rapid installation and removal of the grinding wheel on the external cylindrical grinder is achieved. However, in actual use, the grinder will generate certain vibrations when processing the workpiece, and the vibrations will be transmitted to the threaded rod. Since the threaded connection usually relies on friction to maintain tightness, the vibrations will gradually weaken the friction, thereby causing the threaded rod to loosen, resulting in the inability of the limit fixing component and the limit mechanism to firmly maintain the positioning of the grinding wheel body, causing the grinding wheel to shift in position during the processing process. Therefore, it is necessary to redesign a CNC external cylindrical grinder structure that is easy to maintain in view of the above-mentioned problems. Utility Model Content
