Described fixed mount comprises base 26 and is symmetrically set in the link 27 at described base 26 two ends, the one side that two described links 27 are relative is respectively equipped with a described pressure sensor 16, the described arm of force 15 and two described pressure sensors 16 are just fitted, and the described arm of force 15 can compress described pressure sensor 16 with described fixing pincers 12 rotation.When impact tong 2 drives workpiece to rotate, although fixing pincers 12 are fixed pincers stake body 13 fix, but still can produce microdisplacement along with the rotation of impact tong 2, now fixing pincers 12 can drive the arm of force 15 to produce microdisplacement, the arm of force 15 can apply pressure to pressure sensor 16, now pressure sensor 16 output pressure signal.Along with the process that constantly links closely of impact tong 2, the force value that the arm of force 15 is applied on pressure sensor 16 is larger, just can draw torque value by computing.Being symmetrical arranged two pressure sensors 16 is the technique that links closely in order to coordinate positive and negative both direction.
Described bed ways 1 are also provided with some travelling cars 28.Travelling car 28 is for lifting workpiece.
The operation principle of the invention is as follows:
(1) the fixing jaw mechanism of walking:
Six fixing clamp locking oil cylinders 14 are equipped with for clamping work pieces in walking fixing pincers top.Hydraulic motor 25 is equipped with in bottom, and hydraulic oil drives hydraulic motor 25 to drag the fixing pincers 12 of walking move along bed ways 1 through sprocket wheel, chain engagement.Be realize ground by driving rolls 23 and the friction of bed ways 1 surface scrolls between bed ways 1 and fixing pincers 12, its driving force comes from the driving of hydraulic motor 25 pairs of driving wheels 20.There is little, the mobile feature flexibly of coefficient of friction.Walking wheels 29 are with relocation mechanism-disc spring 24.Automatically the fixing concentricity between pincers 12 and impact tong 2 of walking can be adjusted after Workpiece clamping.Make each clamping cylinder uniform force.Respective six clamping cylinders of the fixing pincers 12 of walking and impact tong 2 all with respective clamping center for the center of circle, six deciles are uniformly distributed and are arranged on fixing pincers 12 and impact tong 2, make each cylinder force even.It is synchronous that every group oil cylinder controls six respective cylinder movements with a synchronized respectively.In the preferred embodiment, what synchronized was selected is U.S. DELTA POWER original product.Synchronization accuracy is high, manually need not adjust synchronization accuracy.
(2) buckle mechanism is rushed:
Six impact tong clamping cylinders 5 are equipped with on impact tong 2 top, for stepping up positioning work.Impact tong 2 is fixed on main lathe bed left end, the outer survey of impact tong 2 is equipped with driving hydraulic motor 25, under the effect of hydraulic oil, hydraulic motor 25 drives the output shaft of planetary reducer 9 to rotate, output shaft by force transmission to pinion 10, pinion 10 by excessive gear 11 just moment of torsion be delivered on gear wheel 3, gear wheel 3 driven rotary axle 6 rotates, rotating shaft drives roller bearing 7 to rotate, rolling bearing 7 drives impact tong 2 rotary work, complete continuous punching and pull work, shorten and improve operating efficiency running time.
(3) drawing mechanism:
Embodiment as shown in the figure, drawing oil cylinder is arranged on drawing support 17.Driving rolls is equipped with in drawing support 17 bottom, and drawing support 17 relies on driving rolls to roll on bed ways 1, the position of adjustable drawing mechanism.According to the length of workpiece (drilling tool rotor), promote the position that drawing mechanism can be adjusted to requirement by drawing support 17.There is 1 the first dowel hole drawing support 17 front portion, and bed ways 1 surface 500mm of being often separated by has 1 the second dowel hole.Latch is inserted in the first dowel hole of drawing support 17 and the second dowel hole of bed ways 1 simultaneously, the position that drawing mechanism is requiring is fixed, ensure that " rotor " of drilling tool can pull-out or loading from " stator " smoothly.
The invention is also provided with Hydraulic Station, electric control system, digital display system and data-printing device.Hydraulic Station be hydraulic oil container, electric box are installed concentratedly with console together with apparatus control part.Console card is equipped with Pressure gauge, torque meter, pressure regulating handle, handles knob and control crank.Pressure gauge display hydraulic system pressure.Torque meter intuitively shows torque value.Pressure switch be used for set needed for force value.Handle knob and control crank to be used to operate machine action.Manipulation knob and control crank bottom indicate Chinese and English two kinds of text operation guides.Not only directly perceived but also facilitate.Hydraulic system can set and reach middle base pressure moment of torsion and high pressure moment of torsion.Can according to the diameter of " pipe " and the suitable moment of torsion of wall thickness different set and clamping force.The geometry of " pipe " is not damaged while ensureing normal work.Can not press from both sides flat and stubborn curved " pipe ".360 degree rotate changer electrical systems and adopt Mitsubishi's programmable controllers, are easier to the various logic requirement realizing hydraulic system compared with traditional relay, not only reduce the use of electrical equipment quantity and safety, reliable, easy to maintenance.Magnetic valve adopts 24 volts of DC voltages, not only protect personal safety and also coil not fragile, increase the service life.This lathe adopts two 15kw machine operation, adopts motor protection switch respectively, integrates overload, short-circuit protection, with alternative electrothermal relay and fuse, saves space.Control circuit adopts two isolating transformers, each self-powered.360 degree of all technical data rotated during changer work, all can be shown by instrument and digital display screen, bring great convenience to the adjustment of lathe and operation, avoid because blindly operating the unnecessary economic loss brought, foundation is provided to the guarantee of work quality.Traditional changer does not have this function.In addition, 360 degree rotate changers and further provided with printer, and by the sequence number of workpiece, the numbering of operative employee, and pressure, torque value during work prints in the lump, ensure that the chased after retrospective of work quality, and the analyticity of liability accident.Traditional changer does not have this function.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
