Embodiment
Example during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 4, comprising: straight pin 1, fixed cover 2, first rise pearl row 3, first retainer 4, second retainer 5, intermediate sleeve 6, second rise pearl row the 7, the 3rd retainer 8, the 4th retainer 9, groups of springs 10, movable sleeve 11, rule body 12 etc.
As shown in Figure 1, the present invention mainly adopts in six circular holes that earlier groups of springs 10 are placed in rule body 12, and described groups of springs 10 is made up of six identical springs.Then movable sleeve 11 is installed in above the rule body 12.The 4th retainer 9 is installed in above the movable sleeve 11, again the 3rd retainer 8 is installed in simultaneously an end of intermediate sleeve 6, and then the intermediate sleeve 6 that the 3rd retainer 8 will be housed is installed on the rule body 12, and such second rises by pearl row 7 under the effect that is subjected to external force, and spring can play the compression adjustment effect.The end that the 3rd retainer 8 is housed then is relative with the 4th retainer 9 on the movable sleeve 11 up, and second pearl 7 of rising is put between the 3rd retainer 8 and the 4th retainer 9 push-tight.Again second retainer 5 is installed in the other end of intermediate sleeve 6, simultaneously first retainer 4 is installed on the fixed cover 2, the fixed cover 2 that first retainer 4 will be housed again is installed in above the rule body 12, first retainer, 4 ends are relative with second retainer 5 on the intermediate sleeve 6 up, again the first pearl row 3 of rising is put between first retainer 4 and second retainer 5, push-tight fixed cover 2 inserts straight pin 1 in the through hole of fixed cover 2 and rule body 12, and in like manner first function and second that rises by pearl row 3 pearl of rising is arranged 7 identical.
The effect of first retainer 4, second retainer 5, the 3rd retainer 8, the 4th retainer 9 prevents that first pearl the row 3 and second pearl row 7 of rising of rising from dropping.Straight pin 1 is to be used for positioning and fixing cover 2 and rule body 12, fixed cover 2, intermediate sleeve 6, movable sleeve 11 is separately made and is installed, purpose be for groups of springs 10 fit adjustment, allow first the rise pearl row 7 of pearl row 3 and second of rising in fixed cover 2 and intermediate sleeve 6 and intermediate sleeve 6 and movable sleeve 11V type groove cooperate with center pit and be subjected to the inwall reacting force when locating, because fixed cover 2, intermediate sleeve 6, movable sleeve 11 all is independently individual, therefore be subjected to first pearl the row 3 and second pearl row 7 of rising of rising to squeeze and press the back because fixed cover 2 is fixed, so power is passed to movable sleeve 11 and intermediate sleeve 6, groups of springs 10 stress deformations are vacateed movable sleeve 11 and intermediate sleeve 6 mobile spaces, thereby because the existence of power reaches aligning location, automatic applying revolving shaft center (referring to Fig. 4).
Shown in Figure 4, below 0.2 be to the location mechanism precompressed ejection amount of establishing, purpose is in order to produce pressure when the patchhole, making wins, and the rise pearl row 7 of pearl row 3 and second of rising is to fit tightly pilot hole in the location.
The present invention allows first rise pearl row 3 and second rise pearl row 7 peripheral diameter and the measured hole interference (referring to figure four) when making.When the present invention locatees, thereby first pearl the row 3 and second pearl row 7 of rising of rising produces extruding with measured hole and forces groups of springs 10 distortion, thereby produces pressure, passes to first pearl the row 3 and second pearl row 7 of rising of rising, force itself and measured hole to fit tightly, thereby improve rotating accuracy of the present invention.Owing to have first pearl the row 3 and second pearl row 7 of rising of rising, also just guaranteed the linear precision of revolving shaft.
The principle of work of the present invention and the course of work:
As shown in Figure 4, in work, detent mechanism is put into center positioning hole by guiding, when the pearl of rising runs into centre of location hole and blocks, detent mechanism and axle center, centre of location hole should be put into almost parallel applies certain external force and makes detent mechanism can enter center positioning hole, first pearl the row 3 and second pearl row 7 of rising of rising makes groups of springs 10 distortion after being stressed, thereby make first rise pearl row 3 and second rise pearl row 7 tightly be attached to the measured hole inwall, guaranteed centre of gyration bearing accuracy, next makes up and down first pearl the row 3 and second pearl row 7 of rising of rising all enter and guarantee the axial linear precision in the pilot hole, thereby plays positioning action under the adjusting of said mechanism principle.
Points for attention of the present invention:
1, rise pearl row will protect purpose with lubricating oil.2, reduce friction force.3, make abrasion reduce to minimum, prevent corrosion phenomenon.
