The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
As shown in Figure 1, the utility model provides a kind of semi-automatic screw thread steel joint tapping machine main drive gear, comprises main shaft 1 and casing 2; The end of main shaft 1 is fixed with screw tap 3; Its concrete fixed form is: the shank of screw tap 3 is installed in the hole of main shaft 1 end; Be provided with spacer shell 15 between the inner hole wall of screw tap 3 and main shaft 1 end; Screw tap 3 is fixedly connected with spacer shell 15 through screw, and main shaft 1 is fixedly connected with spacer shell 15 through connecting pin 16.In addition, also be fixed with slip cap 12 on the outer round surface of main shaft 1, slip cap 12 is positioned at 13 li of slip cap holders, and slip cap holder 13 is fixed on the casing 2.Be with internal spline drive sleeve 4 on the outer circumference surface of main shaft 1, belt pulley 6 and bearing block 7 are housed on the outer round surface of internal spline drive sleeve 4, internal spline drive sleeve 4 adopts key to be connected with belt pulley 6, and bearing block 7 is fixed by bolts on the casing 2; Also be fixed with screw thread pair holder 14 on the casing 2, the screw thread pair holder is equipped with inner screw sheath 8 in 14 holes, is fixed on external thread sleeve 5 on the main shaft 1 and is positioned at inner screw sheath 8 and becomes screw thread pair, is equivalent to the turn-screw pair.External thread sleeve 5 usefulness internal splines are contained on the main shaft 1; The two ends of external thread sleeve 5 are respectively arranged with screw thread pair thrust block 9 and locking nut 10; Screw thread pair thrust block 9 is arranged on the main shaft 1 with locking nut 10; Main shaft 1 between screw thread pair thrust block 9 and the external thread sleeve 5 is provided with Stroke Control bar 11, is provided with bearing between Stroke Control bar 11 and the main shaft 1, and screw thread pair thrust block 9 is fastened on external thread sleeve 5 and Stroke Control bar 11 on the cylindrical of main shaft 1 with locking nut 10.
The operation principle of the utility model is; Belt pulley 6 rotates; Driving main shaft 1 through internal spline drive sleeve 4 rotates; Main shaft 1 is under the effect of screw thread pair (inner screw sheath 8 with external thread sleeve 5), and main shaft 1 moves along the axial direction straight line when rotating, and the rotation of main shaft 1 and straight line move and also drive slip cap 12 straight line in slip cap holder 13 holes simultaneously and move; The straight line that is provided with main shaft 1 of slip cap 12 and slip cap holder 13 has moved the axial location effect, and screw tap 3 can not swung in to the process of screw thread steel joint tapping.The rotation of main shaft 1 adds rectilinear motion and can drive screw tap 3 and carry out tapping work; At this moment; Be arranged on Stroke Control bar 11 on the main shaft 1 also along with main shaft 1 is realized the synchronous linear motion; When Stroke Control bar 11 was run into travel switch, main shaft 1 will stop straight line and move back and reverse moving, and so just can control the stroke of tapping.
The utility model just can carry out tapping to the screw thread steel joint of different size through the spacer shell 15 of changing different-diameter with screw tap 3, and the connecting pin 16 that connects main shaft 1 and spacer shell 15 can not only transmit moment of torsion, and easy disassembly.Drive belt pulley 6 by belt and carry out transmission, the pulling force that belt produces is passed to internal spline drive sleeve 4 through belt pulley 6, transfer to (this is the off-load belt pulley) on the casing 2 through bearing block 7 again, and main shaft 1 only receives the pure torsion effect; In addition, the utility model screw tap that only need change different thread pair (inner screw sheath 8 and external thread sleeve 5) and be furnished with identical pitch can process different screw thread steel joints.Complicated pitch feed mechanism has been simplified in the setting of screw thread pair widely.
