When the tap 12 works for a certain time, the tap 12 needs to be cooled, the first motor 3 is started firstly, the first motor 3 drives the incomplete gear 5 to rotate, the cutter changing disc 2 is driven to rotate through the cooperation of the incomplete gear 5 and the incomplete gear ring 4, the tap 12 is driven to rotate along the center position of the cutter changing disc 2 through the rotation of the cutter changing disc 2, after 90 degrees of rotation, the tap 12 needing cooling moves into the arc-shaped frame plate 20, the first motor 3 is closed and locked, the tap 12 is fixed, then the blower 23 is started, the blower 23 continuously blows air towards the cooling frame 19, air entering the cooling frame 19 enters the arc-shaped frame plate 20 through the vent hole 21, so that the tap 12 is cooled through the air, the air blown out from the vent hole 21 is blown onto the tap 12 more uniformly through the arrangement of the arc-shaped plate 22, the tap 12 is prevented from being damaged due to improper cooling, and the structure is simple, and the cleaning and maintenance in the later stage are facilitated.
When the tap 12 in the working state is cooled to the extent that the tap needs to be cooled, the first motor 3 is started again, and the cutter changing disc 2 and the tap 12 are driven to rotate by 90 degrees through the cooperation of the incomplete gear 5 and the incomplete toothed ring 4, so that the tap 12 in the working state can be cooled for a period of time under the state that tapping operation is not stopped, and the service life of the tap 12 and the dimensional accuracy of tapping are improved.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
