The front end (grinding wheel side) roller is installed on the base through the bearing seat to play a supporting role, and the rear end roller shaft is equipped with a bearing seat. There is also a small sprocket connected to the base, which is connected to the reducer through a chain, which plays the role of supporting and driving the work to rotate. The distance between each group of supporting rollers is adjusted by manually rotating the screw. Start the reducer motor to realize the rotation of the workpiece (tank).

Second, the axial moving device of the grinding head-screw rod (female), grinding head support frame, slide rail (dovetail groove), reducer, motor, etc.

In order to realize the axial feed movement of the grinding wheel along the horizontal centerline of the tank, a threaded screw nut device is installed at one end of the center of the base. On the dovetail groove track, start the motor of the screw reducer, and the screw rotates to push the nut to drive the grinding wheel to move horizontally and axially.

Third, the grinding head group - consists of cantilever, grinding wheel, grinding wheel shaft, motor, V-belt (wheel) and so on.

The cantilever of the grinding head group is installed on the support frame of the grinding head, and the rotation of the grinding wheel is driven by the motor through the triangular pulley (belt) to rotate the grinding wheel shaft installed in the cantilever.

The structure of the original device is relatively complex, the processing cost is high, the screw rod is easy to wear and bend, the failure is frequent, the maintenance cost is high, and the adaptability is not strong.
