[0003] The grinding wheel (including flange plate) of a certain numerical control grinding machine weighs 60 kg. The installation position of the grinding wheel is 1.2-1.3 meters high from the ground. The grinding wheel is fastened by a pair of bolts and nuts on the numerical control grinding machine. The operator usually uses manual removal to replace the grinding wheel.

[0004] Because the bottom of the grinding wheel has no platform, the grinding wheel is suspended. During the usual disassembly process, only one numerical control operator himself can operate. The operator can only hold the grinding wheel with one hand and disassemble the pair of bolts and nuts with the other hand. The inconvenient operation leads to long operation time and easy hand fatigue of the operator. Moreover, the grinding wheel has a large profile and heavy weight. During the operation process, there is a risk of the grinding wheel falling, which poses a safety hazard of hitting the operator's feet. Since the installation of the new grinding wheel is also carried out by manual installation, a plurality of workers need to work simultaneously, which results in low installation efficiency, large assembly difficulty and difficult to effectively avoid the safety risk.

[0042] It can be understood that the pull buckle 33 and the lock hook piece can be conveniently connected and limited to the upper limiting piece 7 and the grinding wheel mounting piece 3. Since the grinding wheel is mainly supported by the grinding wheel mounting piece 3, the upper limiting piece 7 can be locked and connected to the grinding wheel mounting piece 3 through a pull buckle structure with general connection strength. The pull buckle structure can realize quick locking and disassembly of the grinding wheel in the grinding wheel mounting mechanism, ensure that the grinding wheel is not damaged by knocking during transportation, and is convenient and efficient to disassemble and assemble.

[0043] Preferably, the inner walls of the grinding wheel mounting groove 301 and the grinding wheel limiting groove are both provided with a buffer pad 5.

[0044] It can be understood that in order to prevent the large grinding wheel from being damaged during transportation, the upper and lower splicing structure of the grinding wheel mounting mechanism is specially arranged.
