A kind of train guide wheel suspender
Technical field
The present invention relates to fixture, specifically a kind of train guide wheel suspender.
Background technology
The circumferential surface of train guide wheel (abbreviation workpiece) there is an annular boss, when carrying out machine up, need process in its handling to lathe, existing method carries out handling again after adopting steel rope binding, this method, on the one hand, steel rope easy damaged workpiece, on the other hand, not easily locate, this will increase debugging work load, but also may be unsturdy due to binding, cause workpiece landing and have an accident, thus dangerous.
Summary of the invention
Object of the present invention is just to provide the train guide wheel suspender of a kind of novel structure, accurate positioning, easy to operate, safe and reliable, long service life.
For achieving the above object, the present invention includes movable jaw, fixing cambered plate, the slide bar of two elastic clips and two arrangement in parallels, described elastic clip comprises opening folder and two symmetrically arranged elastic clip screws, two limits up and down of described opening folder are arranged with otch, described movable jaw comprises slide, sliding seat locking assembly and two are symmetrically set in the moveable arcuate plate of slide upper-lower position, the right of described slide is provided with slide boss, and on described slide, be provided with two slide circular holes adapted with slide bar size, described sliding seat locking assembly comprises screw rod, handle, upper fixture block, spring cotter and lower fixture block, the root of described otch is provided with the hole adapted with slide bar size, described lower fixture block is provided with the tapped bore adapted with screw flight, described screw rod is successively from bottom to up by lower fixture block, slide boss, upper fixture block connects, and described screw rod is connected with lower fixture block by thread connection, described spring cotter is loaded in the hole of screw rod bottom, described two elastic clips are loaded on left and right two end of two slide bars respectively, and described two slide bars are threaded onto in the circular hole of two elastic clips, the slide of described movable jaw is set on two slide bars, described fixing cambered plate is welded as a whole with the elastic clip being loaded on slide bar right-hand member.
The present invention is owing to have employed the structure be made up of the slide bar of movable jaw, fixing cambered plate, two elastic clips and two arrangement in parallels, elastic clip comprises opening folder and two symmetrically arranged elastic clip screws, two limits up and down of opening folder are arranged with otch, like this, the otch pressed from both sides by the opening of elastic clip by tightening elastic clip screw is pressed little, just can clamp slide bar; Fixing cambered plate is welded as a whole with the elastic clip being loaded on slide bar right-hand member, a fixing jaw can be formed, and the moveable arcuate plate that movable jaw comprises slide, sliding seat locking assembly and two are symmetrically set in slide upper-lower position, the slide of movable jaw is set on two slide bars, these two the moveable arcuate plates being symmetrically set in slide upper-lower position just can form two movable jaws, the position of movable jaw can be adjusted according to the size of workpiece, like this, these three jaws just can be utilized to carry out grabbing workpiece; Sliding seat locking assembly comprises screw rod, handle, upper fixture block, spring cotter and lower fixture block, when needs adjustment activity jaw, just can unclamp screw rod, after movable jaw is moved to correct position, then tighten screw rod, so that locking activity jaw; In addition, be loaded on the spring cotter in the hole of screw rod bottom, both can play position-limiting action, also help and lower fixture block is installed.Novel structure of the present invention, accurate positioning, easy to operate, safe and reliable, long service life.

Detailed description of the invention
See Fig. 1 to Fig. 4, the present invention includes movable jaw 2, fixing cambered plate 4, the slide bar 3 of two elastic clips 1 and two arrangement in parallels, described elastic clip 1 comprises opening folder 11 and two symmetrically arranged elastic clip screws 12, two limits up and down of described opening folder 11 are arranged with otch 111, described movable jaw 2 comprises slide 21, sliding seat locking assembly 23 and two are symmetrically set in the moveable arcuate plate 22 of slide 21 upper-lower position, the right of described slide 21 is provided with slide boss 211, and on described slide 21, be provided with two slide circular holes 212 adapted with slide bar 3 size, described sliding seat locking assembly 23 comprises screw rod 231, handle 232, upper fixture block 233, spring cotter 234 and lower fixture block 235, the root of described otch 111 is provided with the hole adapted with slide bar 3 size, described lower fixture block 235 is provided with the tapped bore adapted with the screw thread of screw rod 231, described screw rod 231 is successively from bottom to up by lower fixture block 235, slide boss 211, upper fixture block 233 connects, and described screw rod 231 is connected with lower fixture block 235 by thread connection, described spring cotter 234 is loaded in the hole of screw rod 231 bottom, described two elastic clips 1 are loaded on left and right two end of two slide bars 3 respectively, and described two slide bars 3 are threaded onto in the circular hole of two elastic clips 1, the slide 21 of described movable jaw 2 is set on two slide bars 3, described fixing cambered plate 4 is welded as a whole with the elastic clip 1 being loaded on slide bar 3 right-hand member.
During use, first clamp the annular boss of workpiece 5 from right side with fixing cambered plate 4, then, handle 232 is used to unclamp screw rod 231, now, just the annular boss of workpiece 5 clamped by moveable arcuate plate 22 that can be symmetrical by two on movable jaw 2 from left side, finally, using handle 232 to tighten screw rod 231 can carry out handling.
In addition, the present invention is not only applicable to the handling of train guide wheel, is also applicable to the handling that any circumferential surface is provided with the cylindrical object of an annular boss.These conversion all drop within protection scope of the present invention.
