The working principle of the internal grinder device is that the motor drives the chuck to rotate through the belt, and the motor is matched with the grinding wheel rotating at high speed to grind products. After the product is processed, the chuck is stopped to disassemble and assemble the product. In the production process, due to the inertia of the motor, after the motor is turned off, the motor rotating shaft still can continuously rotate under the action of the inertia, namely, the chuck is continuously driven to rotate. This results in a longer time for the chuck to stop, resulting in a lower working efficiency. Some emergency staff rotate with hand-pull belts, so that industrial accidents frequently occur, and the belt is quickly stopped by pulling the belts by using tools, if the belt is damaged for a long time, the tension of the belt is damaged, the motor power cannot be transmitted to the chuck due to insufficient tension in the working process of the belt, and the phenomenon of pause is very easy to occur in the working process, so that the size of a product is influenced, and the rejection rate of the product is increased.

Therefore, the belt can be uniformly stressed in the whole width direction, and the damage to the belt is reduced.
In the above-mentioned speed reducing device for assisting the rapid stop of the internal grinding machine chuck, as a preferred embodiment, when the fixed base is fixedly connected with the internal grinding machine chuck, the distance between the two speed reducing wheels and the belt is 0.1-0.15mm.
In the normal operation process of the belt, the speed reducing wheel does not apply acting force to the belt, and normal use of the belt is not affected.
In the above-mentioned speed reducing device for assisting the rapid stop of the chuck of the internal grinding machine, as a preferred embodiment, a spring is horizontally arranged in the opening of the fixed base;
when the spring is in an original length state, the opening degree of the fixed base is in a natural state, and the speed reducing wheel is not contacted with the belt;
when the spring is in a compressed state, the opening degree of the fixed base is reduced, and the speed reducing wheel presses the belt.
The arrangement of the springs can ensure that the belt has no external force when in normal operation, the speed reducing wheel can not influence the operation of the belt, and the fixed base can be helped to restore the original state when no external force exists.
The fixing base used in the utility model can be made of soft iron or aluminum.
The beneficial effects of the utility model are as follows: the speed reducer for assisting the quick stop of the internal grinding machine chuck can enable the belt to be quickly stopped under the condition that the belt is not damaged, so that the clamping internal grinding machine chuck is quickly stopped, the use is convenient, the working efficiency is ensured, and the industrial accident is reduced.
