The utility model provides an adjustable inner groove
thinning device which comprises a clamping mechanism, the clamping mechanism is used for fixing a plurality of round pipes at equal intervals, a transverse moving mechanism is arranged on one side of the clamping mechanism, a
thinning mechanism and a
grinding mechanism are arranged at the output end of the transverse moving mechanism, and the
grinding mechanism is used for
grinding the round pipes. The transverse moving mechanism drives the
thinning mechanism and the grinding mechanism to transversely move, the thinning mechanism is used for
cutting an inner groove in the end of the round
pipe, the grinding mechanism is used for grinding the inner groove, and the transverse moving mechanism is fixed to the upper end of the lifting table. A plurality of circular pipes are fixed through the clamping mechanism, the height of the thinning mechanism and the height of the
polishing mechanism are adjusted through the lifting table, then the thinning mechanism and the
polishing mechanism are driven by the transverse moving mechanism to transversely move, the
machining position is conveniently adjusted, and therefore inner groove
cutting and inner groove
polishing are sequentially conducted on the circular pipes; and inner groove
cutting and surface polishing tasks can be rapidly and accurately completed, and the production efficiency is improved.
