Detailed description of the invention
In order to deepen the understanding of the present invention, be described in further detail of the present invention below in conjunction with embodiment and accompanying drawing, this embodiment, only for explaining the present invention, does not form the restriction to protection scope of the present invention.
As shown in Figures 1 to 9, semi-automatic screw thread prosthetic appliance, comprise power set, the rotating shaft output device of horizontal positioned and screw thread pusher, power set comprise motor 1(1.1KW-380V alternating current generator), rotating by-pass cock 2 and foot-actuated switch 3, the rotation of motor output shaft 7 operates by riding, when gag lever post touches limit switch 25, limit switch 25 is connected with foot-actuated switch 3, also can allow motor stalls, the rotating of motor output shaft is controlled by rotating by-pass cock 2.
Rotating shaft output device comprises reduction box 4, transition piece 5, die clamp 6, and motor 1 is connected with reduction box 4 by motor output shaft 7, by the speed reducing ratio of 1:30, and output speed 50r/min.The output shaft 8 of reduction box is connected with die clamp 6 by transition piece 5, screw thread pusher comprises the guide rail 9, bolted fixture 10 and the crank mechanism that are made up of the H profile steel of two parallel placements, bolted fixture 10 is fixed in clamp base 11, is provided with cushion block 18 between bolted fixture 10 and clamp base 11.Be provided with guide rail slide block 12 between the H profile steel of two parallel placements, guide rail slide block 12 is by fixing with bolt between the guide rail clamp 13 below it and clamp base 11.The side of bolted fixture 10 is provided with gag lever post governor motion, gag lever post governor motion comprises gag lever post 22, pressing plate 24 and limit switch 25, pressing plate 24 while be positioned on cushion block 18, be fixed in clamp base by fastening bolt 23, compressed by pressing plate 24 in the space of gag lever post 22 between cushion block 18 side clamp base 11 and pressing plate 24, limit switch 25 is positioned at the front of gag lever post 22 and the guide rail one end be fixed near rotating shaft output device.Because the reach of bolt is different, according to actual thread length adjustment gag lever post 22 extension elongation of bolt to be repaired before operation, when guaranteeing concordant outside thread root and the screw die of bolt, gag lever post 22 just in time touches limit switch 25, and gag lever post 22 is fixed in clamp base 11 by fastening bolt 23 and pressing plate 24.When the object that limit switch 25 can reach motor stalling touched by gag lever post 22 during operation, so more accurately can control the length of repairing screw thread, the time avoiding screw thread to repair root the problem of control, should not also improve security.
Crank mechanism comprises crank 14 and the disk 16 with push rod 15, and disk 16 is fixing on the rail 9, and crank 14 one end is connected with disk 16, and the other end is fixed between bolted fixture 10 and clamp base 11 by bearing pin 17.Utilize crank 14 to push, make the working range of clamping part strengthen (L100mm-L400mm), when push rod 15 promotes to the right, crank 14 drives guide rail slide block 12 to move, bolted fixture 10 forward impelling, makes bolt contact with screw die, when after the first pitch thread occlusion, bolt automatically move forward to, when gag lever post 22 touches limit switch 25, namely motor stops operating, and now screw thread is repaired complete, can unclamp foot-operated, rotating by-pass cock is pushed backward position and exits screw thread.
Change die clamp 6 into screw tap clamp 20 and fix screw tap, bolted fixture 10 is replaced with nut clamp 21, the screw thread of nut is repaired.
In addition, quick position can be made it for conventional stud and nut arrange special fixture, avoid repeating adjustment.
