Vertical pipeline latheTechnical field
The present invention relates to a kind of cutting element of pipeline, particularly relate to a kind of vertical pipeline lathe.
Background technology
Oil well casing sinks due to ground surface, and mouth of pipe relative elevation rises, and the operating efficiency of oil pumper reduces, and original pipeline will be cut off one section like this, then carry out the processing of mouth of pipe tapered thread.At present, market lacks portable vertical cutting equipment, can only cut unnecessary pipeline by operating personnel with hacksaw, not only labour intensity is large, and the physical dimension of work piece is mostly also undesirable.
Summary of the invention
The present invention want technical solution problem to be to provide one can to carry out machining to cylinder at the construction field (site), and the vertical pipeline lathe of the physical dimension required for work piece can be reached.
In order to solve above-mentioned technical problem; The technical scheme that vertical pipeline lathe of the present invention adopts is: it comprises holder, holder is connected with lathe base plate, lathe base plate is provided with bottom bracket axle, bottom bracket axle is connected with swivelling tool-holder with upper bearing (metal) by lower bearing, lathe base plate is provided with initiatively motor, initiatively the output shaft of motor passes through the second gears meshing of the first gear and swivelling tool-holder lower endswivelling tool-holder upper end is provided with axial direction electric machine and axial screw, and axial screw is also provided with nut gearthe output shaft of axial direction electric machine is engaged with the nut gear be arranged on axial screw by the 3rd gear, the lower end of axial screw is connected with middle supporting plate slide plate, middle supporting plate slide plate is arranged on middle supporting plate base plate, middle supporting plate base plate is arranged on swivelling tool-holder, and middle supporting plate slide plate is provided with little supporting plate base plate, and little supporting plate base plate installs radial motor, the output shaft of radial motor is connected with little supporting plate slide plate nut by screw mandrel, and little supporting plate slide plate is provided with lathe tool.
Described upper bearing (metal) is compressed by the bearing gland be arranged on bottom bracket axle.
Holder is arranged on processed steel pipe by technique scheme, and lathe base plate is connected with holder, and initiatively motor is rotated around bottom bracket axle by the first gear, the second gear driven swivelling tool-holder; Lathe tool completes the cutting to workpiece under the driving of axial direction electric machine and radial motor.Therefore, the present invention can carry out machining to cylinder at the construction field (site), and can reach the physical dimension required for work piece, alleviates labour intensity, Portable practical, rational in infrastructure.
Accompanying drawing explanation
Fig. 1 is the structural representation of vertical pipeline lathe of the present invention.
Detailed description of the invention
As seen from Figure 1, vertical pipeline lathe of the present invention comprises the holder 1 be arranged on steel pipe 22, holder 1 is connected with lathe base plate 3 by set bolt 2, lathe base plate 3 is provided with bottom bracket axle 4, bottom bracket axle 4 is connected with swivelling tool-holder 7 with upper bearing (metal) 6 by lower bearing 5, upper bearing (metal) 6 is compressed by the bearing gland 8 be arranged on bottom bracket axle 4, lathe base plate 3 is provided with initiatively motor 9, initiatively the output shaft of motor 9 is engaged with the second gear 11 of swivelling tool-holder 7 lower end by the first gear 10, the upper surface of swivelling tool-holder 7 is provided with axial direction electric machine 12, axial nut gear 15 is also installed, the output shaft of axial direction electric machine 12 is engaged with the nut gear 15 being arranged on axial screw 13 upper end by the 3rd gear 14, the lower end of axial screw 13 is connected with middle supporting plate slide plate 16, middle supporting plate slide plate 16 is arranged on middle supporting plate base plate 17, middle supporting plate base plate 17 is arranged on swivelling tool-holder 7, middle supporting plate slide plate 16 is provided with little supporting plate base plate 18, little supporting plate base plate 18 installs radial motor 19, the output shaft of radial motor 19 is connected with little supporting plate slide plate 20 nut by screw mandrel, little supporting plate slide plate 20 is provided with lathe tool 21.
Operation principle of the present invention is: be arranged on processed steel pipe 22 by holder 1, and make holder and steel pipe 22 form an entirety, lathe base plate 3 is connected with holder 1; Initiatively motor 9 is rotated around bottom bracket axle 4 by the first gear 10, second gear 11 driven rotary knife rest 7;
The output shaft of axial direction electric machine 12 is engaged with the nut gear 15 being arranged on axial screw 13 upper end by the 3rd gear 14, and nut gear 15 rotating band is moved axial screw 13 and slid axially with middle supporting plate slide plate 16, completes axial feed.
The output shaft of radial motor 19 is connected with little supporting plate slide plate 20 nut by screw mandrel, and little supporting plate slide plate 20 is provided with lathe tool 21.The output shaft rotation of radial motor 19 drives little supporting plate slide plate to radially slide by screw mandrel and nut, completes axial feed.
Lathe tool 21 completes the machining to workpiece (steel pipe 22) under the driving of axial direction electric machine 12 and radial motor 19.
