Description
Technical field
The utility model relates to the prosthetic appliance of the special-purpose spare part of a kind of steel-making continuous casting, specifically a kind of threads of lead screw prosthetic device.
Background technology
In the steel-making continuous casting production system, if behind stopper screw rod temperature distortion or the surperficial dry slag, generally all do to scrap processing, the daily expendable part of Chang Zuowei uses.If the screw thread of leading screw is repaired with engine lathe, to repair requirement and need operate, and can not repair distortion back screw rod by the workman of professional skill, there is certain limitation in repair.If adopt artificial the reparation, working strength is big, efficient is low, calculates and finishes this not as buying new spare part.
Summary of the invention
The utility model is the deficiency at existing leading screw prosthetic appliance and method, and a kind of simple in structure, threads of lead screw prosthetic device that repairing effect is good is provided.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of threads of lead screw prosthetic device, comprise frame, be installed in the motor and speed reducer of frame end, transmission arm is housed on the reductor, the bearing block of suit is installed in frame top on this transmission arm, also comprise the anchor clamps that are installed in the frame other end, wherein:
The end of a, described transmission arm is provided with the installation groove, is set with the leading screw fixture on this installation groove;
B, described clamp base are provided with the slide of band slideway, and this slide top is equipped with the inner holder of being with briquetting by locating shaft, and rotating disc is equipped with at the slide top, and this rotating disc is arranged on the outside of locating shaft;
C, described frame are connected with track on putting the beams in place, and this track matches with the slideway of clamp base.
Compared with prior art, the utility model is simple in structure, nut can be withdrawed from screw thread reparation and finish together, has improved operating efficiency greatly; This device is simple to operate, and common staff just can finish repair, and is convenient and swift.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the structural representation of anchor clamps.
Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to accompanying drawing 1-3, in the present embodiment, this threads of lead screw prosthetic device, comprise frame 11, be installed in the motor 1 and the reductor 2 of frame 11 ends, transmission arm 3 is housed on the reductor 2, the bearing block 4 of suit is installed in the top of frame 11 on this transmission arm 3, also comprise the anchor clamps 8 that are installed in frame 11 other ends, wherein:
The end of transmission arm 3 is provided with installs groove 5, is set with screw thread repair member 6 on this installation groove 5, and generally, this screw thread repair member 6 comprises the sleeve that is used for the nut on the removal leading screw 7, and the screw die that is used to repair screw thread on the leading screw 7.
Be connected with track 10 on the upper beam 9 of frame 11, these track 10 structures triangular in shape, track 10 matches with the slideway 19 of clamp base, and promptly anchor clamps can move horizontally on frame is put the beams in place by the cooperation of slideway and track.
Briquetting is divided into upper holder block 15 and lower lock block 16, and lower lock block 16 is fixed on holder 17 inside bottom, and upper holder block 15 is lifted on the crossbeam 14 at holder 17 tops by the jackscrew affixed with it 13.
Rotating disc 21 is a loop configuration, and rotating disc 21 inside evenly are equipped with movable steel ball 22.
General distortion leading screw 7, when threads of lead screw damaged, itself also can there be certain flexural deformation in leading screw 7.When repairing threads of lead screw, need earlier the nut removal on the leading screw, and then the screw thread on the leading screw 7 repaired, because general anchor clamps 8 just play fixation, when leading screw 7 itself also is out of shape, the work of repairing screw thread will become very complicated, so this device also has one can be under the situation of leading screw distortion itself, still can guarantee the good anchor clamps of screw thread repairing effect 8, be provided with a rotating disc in these anchor clamps, make that fixedly the holder of leading screw can planar rotate, such design can reduce the moment of torsion to the distortion leading screw, guarantees its requirement of strength.
Using method of the present utility model is:
Earlier with sleeve set in the installation groove of transmission arm end, end with leading screw 7 steps up with anchor clamps 8 then, the other end puts in the sleeve and fixes, owing to have rotating disc 21 on the anchor clamps 8, the holder 17 on anchor clamps 8 tops can be done the rotation of certain angle according to leading screw 7 distortion situations own so, open universal switch 12, transmission arm 3 rotatablely moves under the drive of motor 1 and reductor 2, selects the rotating of motor 1 with the control of universal switch 12 according to the rotation direction of screw thread.Leading screw 7 is along hand of spiral moving linearly above the upper beam 9 of frame 11, and nut withdraws from.
Unload through sleeve then, change screw die, repeat the above-mentioned course of work, just can realize the repair of screw die threads of lead screw.
Screw die is fixing for convenience, and the installation groove 5 of transmission arm 3 is made into square groove, and the screw die bottom simply processes, and is made into square projection, and like this, the two can fixedly mount by matched in clearance, and then gets final product with connector is fixing.
