Embodiment
Soft shaft fine adjustment self locking device is made up of flexible axle spare, adjustment piece and fixed block three parts generally as shown in Figure 1.
The cylindric backguy joint 14 that so-called flexible axle spare mainly comprises an adjustable metal backguy 18 in position and is fixedly connected with it.Backguy joint 14 is installed in the cylindrical cavity of the rounded fixed tube 15 in cross section, fixed tube 15 is fixedly connected by an internal thread and an end that is shaped on corresponding externally threaded threaded pipe 12, fixed tube 15 cavitys radially wrap up backguy joint 14, axially allow backguy joint 14 to move within the specific limits.Be shaped on a smooth, spherical depression on the backguy joint 14, connect with the terminal formation activity of the smooth sphere of the backguy pull head 10 that will be described below.
So-called adjustment piece comprises standing part and active part.
Standing part is circular threaded pipe 12 by a cross section mainly and is fixedly mounted on respective diameters in these threaded pipe 12 inner threads and the spring 13 of pitch is formed spiral chute of these spring 13 matching thread pipes, 12 formation.Standing part comprises also and threaded pipe 12 outside thread nut engaged 11 that this nut 11 is fastened on threaded pipe 12 on the affiliated mechanical fixed plate 9.Standing part also comprise a locking nut 7 of scyewed joint threaded pipe 12 1 ends and be fixedly mounted on threaded pipe 12 and locking nut 7 between an elastic annular lining 4, locking nut 7 possesses one and is suitable for hand, refers to that the coarse knob shape profile of grasping and one are near the tapered internal surface in steel pipe 3 positions, correspondingly, ring-type lining 4 possesses a diameter and similar rounded internal surface and the outer surface that the part is tapered of steel pipe 3 external diameters.When tightening locking nut 7, the cone-shaped inner surface of locking nut 7 compresses the conical outer surface of lining 4, cause lining 4 internal surfaces to be close to steel pipe 3, huge frictional force makes both can't relative movement, this just means that steel pipe 3 is fixedly positioning, and can not produce displacement with respect to fixing threaded pipe 12 because of the integral body vibrations of its corresponding device and machinery; When unscrewing locking nut 7, the cone-shaped inner surface of locking nut 7 loosens the conical outer surface of lining 4, and 3 frictional force of lining 4 and steel pipe reduce, and both can relative movement, and this just means that steel pipe 3 can produce displacements with respect to fixing threaded pipe 12.
Active part is connected with described backguy joint 14, mainly the round steel pipe 3 that is slightly less than described spring 13 internal diameters by an external diameter is socketed in an external diameter and is slightly less than that the circular steel pole 5 of described steel pipe 3 internal diameters is outer to be constituted, on described steel pipe 3 tube walls, be shaped on a circular hole, be shaped on a pit in described steel pole 5 local radial, pit is placed a spherical steel ball 6, and described Circularhole diameter is less than steel ball 6 diameters.The shape of pit is along being in the shape of the letter V on the described steel pole 5 center line axial sections, and pit depth is enough to make steel ball 6 to break away from the spiral chute that described spring 13 matching thread pipes 12 form when falling into the pit bosom.Active part also comprises the backguy pull head 10 that the end with described steel pipe 3 is fixedly connected, and backguy pull head 10 has a planar end and a smooth sphere end.Pretension is installed a stage clip 8 between the planar end of described steel pole 5 and backguy pull head 10, and pretightening force is formed by steel pole 5 compressings by manpower and kept by clamping steel ball between described circular hole and the pit 6.The part that steel ball 6 is exposed at outside the described circular hole heads in the spiral chute of described spring 13 matching thread pipes 12 formation, exactly, be to withstand on the described spiral chute on spring 13 steel wires away from stage clip 8 one sides, thereby whole described adjustment piece active part is locked in the described adjustment piece standing part.The sphere of described backguy pull head 10 is terminal to be connected with backguy joint 14 activities with corresponding smooth sphere depression, because the radially parcel of aforementioned fixation pipe 15 cavitys, backguy pull head 10 neither can break away from backguy joint 14, again can with steel pipe 3 freely rotate and not tension wire terminal 14 pin down.In the present embodiment, active part also comprises a plastic steel base 2 that is fixedly connected with described steel pipe 3, steel-tube seat 2 possesses one and is suitable for hand, refers to the knob shape profile of grasping and coarse surface, can rotate steel pipe 3 like a cork by rotating this steel-tube seat 2, driving steel ball 6 moves along described spiral chute, realize steel pipe 3 and backguy pull head 10 microdisplacement, therefore realize the accurate adjustment of backguy 18 positions with respect to threaded pipe.Active part also comprises a plastics steel pole cover 1 that connects with described steel-tube seat 2 internal activities, steel pole overlaps 1 profile and is cylindric, has flexibility, button-like projection of formation outside described steel-tube seat 2 is exposed in the part, the internal surface end face of steel pole cover 1 depression compresses mutually with the end face of described steel pole 5, manpower is pushed steel pole and is overlapped 1 button-like jut and steel pole 5 can be promoted a distance to stage clip 8 directions, make steel ball 6 fall into the pit bosom of described steel pole 5 and break away from the spiral chute that described spring 13 matching thread pipes 12 form, at this moment, just can realize immediately that by push-and-pull steel-tube seat 2 described adjustment piece active part is with respect to standing part moving in a big way.Certainly, this mobile scope also is conditional, and it must can move distance smaller or equal to described backguy joint in described fixed tube 15 cylindrical cavities.After this moving in a big way carried out in described adjustment piece active part push-and-pull backguy 18, open the manpower of pushing steel pole cover 1 as long as remove, under the elastic force effect of stage clip 8, steel pipe 3 and steel pole 5 be clamping steel ball 6 and make it part and head in the spiral chute that described spring 13 matching thread pipes 12 form immediately again, thereby be locked in the position of described adjustment piece active part once more, therefore the position of backguy 18 obtains locking.
