Description

Technical Field

[0001] This invention belongs to the field of disassembly and assembly technology, and specifically relates to a grinding wheel disassembly and assembly device for a grinding machine. Background Technology

[0002] In modern machining, small and medium-sized cylindrical grinders and universal grinders mostly use manual assembly and disassembly of grinding wheels, while large grinders mostly use mechanical puller assembly and disassembly. These methods are not only extremely labor-intensive but also consume a significant amount of time. The force is applied to the grinder spindle end face via bolts, requiring balanced and simultaneous tightening for operation. This necessitates the work of at least two people; even slight imbalances in the bolts can prevent operation and easily damage the grinder spindle, leading to accuracy errors, equipment damage, and economic losses. The operation process is labor-intensive, with low production efficiency and safety.

[0003] Currently, patent number 201921272023.2 discloses a grinding wheel disassembly and assembly device for a grinding machine, belonging to the field of grinding wheel technology. It includes a support frame with horizontal and vertical fixed plates, a vertically movable up-and-down mechanism, a front-and-back movable mechanism, a left-and-right movable mechanism, and a grinding wheel fixing frame with a groove for supporting the grinding wheel. This grinding wheel disassembly and assembly device can reduce the labor intensity of operators, lower labor costs, and improve production efficiency; it can also stably support the grinding wheel, preventing sagging or swaying during installation and disassembly, thus providing higher safety; furthermore, it prevents collisions during installation and disassembly, protecting the tapered hole accuracy of the grinding wheel flange and the spindle accuracy, ensuring the service life of the grinding wheel flange and spindle, and ensuring the installation accuracy of the grinding wheel. However, when using this grinding wheel disassembly and assembly device, it cannot automatically extend, rotate, adjust, or adjust according to usage needs, nor can it provide dual adjustment, locking, and clamping functions based on different grinding wheel specifications, further reducing the efficiency of grinding wheel disassembly and assembly.

[0004] Therefore, the problem that the aforementioned disassembly and assembly device cannot automatically extend, rotate, adjust, and install / remove according to usage needs urgently needs to be solved in order to improve the usage scenarios of the disassembly and assembly device.
