Abstract
The invention provides an internal grinding device for a grinder, which comprises a grinding wheel device, a bracket structure, a coupler and a main shaft. The grinding wheel is connected with one end of the main shaft which uses the bracket structure as a support. The other end of the main shaft is connected with the coupler which serves as a connecting piece for transmitting power by a motor. The grinding wheel comprises a grinding wheel shaft and a grinding wheel. The grinding wheel is fixed at the end part of the grinding wheel shaft, and the grinding wheel shaft is connected on the main shaft, coaxial with the main shaft and connected by keys. The bracket structure comprises a shell, a sleeve, a spring and four bearings which support the main shaft. The four bearings are respectively arranged at both ends of the main shaft. A shaft sleeve is arranged on the inner ring, a sleeve is arranged on the outer ring, the sleeve is connected in the shell and divided into two sections, and the two sections are connected by a spring. The internal grinding device for the grinder realizes a pre-tightening force through a spring structure so as to bring stability under high speed operation and meet the demand of grinding precision of the grinder.
