The specific embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
See also Fig. 1～Fig. 2, Fig. 3 a～Fig. 3 b, Fig. 4 a～Fig. 4 b and Fig. 5～shown in Figure 6, the utility model provides a kind of nut installing mechanism, it comprises: one is used for nut 11 held up and make it the rotating unit that rotates around its axial line, a grip unit that links to each other with rotating unit and a balance hanging piece 8 of being located on the grip unit and can the edge moving horizontally.Rotating unit is used for assembling is finished in the vertically fixing and flexible rotation of nut 11.Wherein rotating unit comprises: one is formed with one at least is used for the first spacing boss 101 and the minor axis 1 of one second boss 102, one with minor axis 1 on each boss match and turning set is located at brass bushing 2 on the minor axis 1, be located in the brass bushing 2 respectively, first boss 101 of minor axis 1 and the deep groove ball bearing 3 of two big models on second boss 102, and one first end cap 4 and one second end cap 5.Brass bushing 2 inwalls are formed with and are used for step 202 in the spacing one first interior step 201 and one second.Deep groove ball bearing 3 by step 201, second interior 202, two big models of step in first in first end cap 4, second end cap 5 and the brass bushing 2 is installed on the minor axis 1 vertically.
Grip unit is used for both ends of the surface 1101,1102 clampings with nut 11, makes it crosswise fixed.Grip unit comprises: baffle plate 9 and movable respectively two the small-sized deep groove ball bearings 3 being located on connecting plate 6 and the baffle plate 7 on the major axis 7 are located in 7, one activities of a connecting plate that is used to connect 6, one major axis.Wherein, the bottom of connecting plate 6 and minor axis 1 vertical wearing.Major axis 7 and minor axis 1 are parallel and wear with the upper vertical of connecting plate 6.Two deep groove ball bearings 3 are positioned on the same horizontal line.Grip unit also comprise the small-sized deep groove ball bearing 3 of diaxon bearing sleeve 10,12, two respectively activity be located in the diaxon bearing sleeve 10,12, wherein a bearing holder (housing, cover) 10 is fixedly arranged on baffle plate 9 belows, another bearing holder (housing, cover) 12 is fixedly arranged on the middle part of connecting plate 6.Installing one alignment pin on the baffle plate 9, the baffle plate 9 that is used for adjusting is radially fixed along major axis 7.
In the present embodiment, the standing part of deep groove ball bearing and major axis or minor axis is a known technology, does not give unnecessary details at this.
Operation of the present utility model is as follows: with the crane gear joint hinge of slinging, baffle plate 9 is screwed into horizontal level, brass bushing 2 parts are stretched in the nut screw (note: the internal thread of nut 11 has only and most ofly contacts with brass bushing 2, another part is exposed), nut left side 1102 is contacted with small-sized deep groove ball bearing 3 on the bearing holder (housing, cover) 12.Try to sling nut 11 by starting crane gear, this moment is because the position relation of joint hinge, the nut of slinging 11 is in the vertical direction not, by the position of mobile joint hinge on major axis 7, make the pulling force on the joint hinge and the gravity of nut 11 on a vertical straight line, constitute equilibrium of forces, thereby make the axial line of nut 11 be in level.With screw joint hinge is fixed on the major axis 7 by the locating hole on the joint hinge; Screw off baffle plate 9 simultaneously to the vertical direction position, and slide damper 9 makes the small-sized deep groove ball bearing 3 on the bearing holder (housing, cover) 10 contact with nut right side 1101, and the screw on the locking baffle plate 9, baffle plate 9 is fixed on the major axis 4.At this moment, nut 11 is in the crosswise fixed state.Move this mechanism by crane gear, nut inner thread is contacted with another workpiece external screw thread, when if nut inner thread can not contact another workpiece external screw thread fully on whole circumference, can continue to adjust the position of joint hinge, on whole circumference, all touch until nut inner thread, workpiece external screw thread.Use external force rotation nut 11, in nut 11 rotating process,, will rotate and withstand all the time the both ends of the surface 1101,1102 of nut 11 with nut 11 because two small-sized deep groove ball bearings 3 can freely rotate; Nut 11 is fixed at left and right directions.Because the rotation of nut 11, will make nut 11 slowly on another workpiece external screw thread of precession, after nut 11 screws in another workpiece certain distances, again baffle plate 9 is threaded to horizontal level, continue rotation nut 11 then, on another workpiece external screw thread of whole screw-ins.
Adopt the utility model, even also nut 11 can be installed quickly and safely than narrow space.In addition, in the whole process that nut 11 is being sling, be to be in stationary state, be difficult for dropping, can guarantee the security in nut 11 installations, simultaneously, nut 11 is set on the brass bushing 2, and the internal thread of nut 11 can be worn.Because but therefore joint hinge horizontal slip on major axis 7 can make things convenient for the various states of transfer nut, and owing to the deep groove ball bearing 3 that in the brass bushing 2 is two big models can be converted to slip rolling, nut 11 can be rotated very like a cork assemble.
Directionality term in the utility model specific embodiment as upper and lower, left and right etc., all is to express present embodiment and adopt for clear, must not be as the qualification to technical solutions of the utility model itself.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
