Description

Technical Field

[0001] This utility model relates to the field of resin grinding wheel technology, specifically to a resin grinding wheel with automatic coaxiality function. Background Technology

[0002] Resin grinding wheels are made of resin. They are high-strength and used in cutting discs, double-end grinding wheels, heavy-duty grinding wheels, polishing wheels, etc. They have a certain degree of elasticity, low heat resistance, good self-sharpening properties, are easy to manufacture, and have a short process cycle. They are widely used in rough grinding, finishing grinding, cutting, and free grinding.

[0003] In modern machining, resin grinding wheels are widely used in precision machining applications such as metal cutting and surface polishing due to their excellent elasticity, polishing properties, and low grinding force. However, with the continuous improvement of machining accuracy and efficiency requirements, the problem of heat accumulation caused by intense friction during high-speed operation of resin grinding wheels has become increasingly prominent. When the grinding wheel rubs continuously with the workpiece, the temperature of the contact area can rise sharply to 300℃ or even higher in a short period of time. Excessive temperature not only accelerates the aging and decomposition of the resin binder, leading to a decrease in grinding wheel hardness and abrasive grain shedding, but may also cause thermal deformation and metallographic changes on the workpiece surface, seriously affecting machining accuracy and surface quality. Currently, most machining companies still use the traditional method of natural cooling to deal with the overheating problem of grinding wheels. This passive heat dissipation method, which relies on air convection and heat conduction, requires the high-temperature grinding wheel to be left to stand for several hours or even longer to allow its temperature to drop to a safe operating range. For example, when a certain automotive parts manufacturing company uses a 400mm diameter resin grinding wheel to grind brake discs, a single natural cooling process takes as long as 3-4 hours. The time spent in natural cooling not only significantly increases equipment downtime but also creates a severe bottleneck in the production line, reducing processing efficiency by approximately 40% and forcing longer production cycles, directly impacting order delivery schedules. Furthermore, the limitations of natural cooling are also reflected in its high dependence on environmental conditions. In hot and humid summers or enclosed workshops, air heat dissipation efficiency decreases significantly, further exacerbating the cooling time problem. Moreover, grinding wheels subjected to prolonged high temperatures undergo irreversible chemical changes in their internal structure, weakening the bonding strength of the binder and posing a safety hazard of grinding wheel breakage during subsequent use. These drawbacks make natural cooling methods unable to meet the demands of modern manufacturing for efficient and continuous production, necessitating the development of more advanced cooling technologies to overcome this bottleneck.

[0030] In order to achieve the purpose of fixing the grinding wheel body 8, the device adopts the following technical solution: the fixing unit includes a connecting plate 7, which is fixedly sleeved on the outside of the rotating rod 6.
