The crankshaft mounted to a ship etc. is provided with the large chain wheel connected by the drive body which rotates, and a chain.

Thus, the rotation of the crankshaft can be made in accordance with the rotation of the chain wheel.

In such a chain wheel, the edge of each tooth is sharply made in the first place. Therefore, if the chain is fastened to the chain wheel immediately after the production, the chain is not only damaged when the tooth edge of the chain wheel is in contact with the chain. There was a problem that damage to the chain wheel itself, such as cracks on the edge.

For this reason, the chain wheel is subjected to grinding of the teeth of each tooth before use.

Grinding each tooth edge of the chain wheel rounds the edges so that even when the chain is used, the chain can be prevented from being damaged or the chain wheel itself.

On the other hand, the conventional chain wheel edge grinding method is that the operator squatted adjacent to the chain wheel to polish the edge of one tooth with a polishing device and move to one side to polish the edge of the other tooth adjacent to the polished tooth.

Although the conventional chain wheel polishing method as described above is capable of polishing each tooth edge of the chain wheel, there was a problem that it takes a considerable time to polish the edge of a large chain wheel formed with a plurality of teeth, the operator uncomfortable posture Since working on the furnace, fatigue of the work had a considerable problem.

For this reason, the field is seeking ways to facilitate the edge grinding of the chain wheel more easily and quickly, but until now, satisfactory results have not been obtained.

The present invention has been proposed in view of the above situation, and a chain wheel edge grinding work holder can solve a problem that a considerable time is required for edge grinding of a chain wheel and a fatigue problem of edge grinding work of a chain wheel. The purpose is to provide.

Support legs to maintain a constant height from the ground;

A seating plate rotatably coupled to the upper end of the supporting leg;

A driven gear provided at the bottom center of the seating plate;

A drive gear meshing with the driven gear and rotating forward and backward according to a motor drive;

It characterized in that it comprises a foot switch for controlling the motor drive of the drive gear.

Here, the seat plate is characterized in that the rotation by a predetermined angle by the motor drive control through the foot switch.

And the motor is characterized in that the decelerating rotation by the reducer.

According to the present invention, the holder for the chain wheel edge polishing operation is to rotate the seating plate by operating the footswitch while the chain wheel is seated on the seating plate because the seating plate on the support leg is rotated at a predetermined angle by the footswitch operation. Since the edge of the tooth can be polished, the operator can perform the polishing operation without moving in a comfortable posture, so that the polishing operation can be performed simply and quickly, thereby maximizing the efficiency of the chain wheel polishing operation.
