Specific embodiment

The technical solution of the utility model is described in further detail with reference to the accompanying drawings and detailed description, this Utility model proposes a kind of embodiment for being used to adjust the eccentric adjuster between articulation piece, is mainly used for realizing for hinged Disalignment between two components carries out micro adjustment, and the final installation accuracy for ensuring product ensures mutually to cut with scissors Two parts connect should meet center line after the completion of assembling to be located along the same line.Specifically, the eccentric tune in the present embodiment Regulating device includes eccentric bushing 1 and available for eccentric bearing 2 is adjusted, and articulation piece includes upper articulation part 3,4 and of lower hinge Articulated shaft 5, when specifically carrying out assembly connection, lower hinge 4 is set on the articulated shaft 5, and bearing 2 is set in described hinged On axis 5, eccentric bushing 1 be set on bearing 2 and with 3 detachable connection of upper articulation part.

Bearing 2 can realize to the center line between upper articulation part 3 and lower hinge 4 there is a situation where left and right offset into Row adjustment, i.e., axis is misaligned between two articulation pieces up and down, there is angle.At this moment, articulated shaft tilts, and is adjusted, made by bearing 2 Its axis overlaps, since bearing 2 itself can automatically be adjusted bias, i.e., when in upper articulation part 3 and lower hinge 4 During heart line deflection, bearing 2 can pass through adjustment of itself scrolling realization to its a small range or so eccentric direction.Preferably, this reality It applies the bearing 2 in example and selects oscillating bearing, it is internal to have spherical be to should automatically be adjusted to a certain range of bias Whole, certainly, bearing 2 or spherical bearing or self-aligning ball bearing in the present embodiment, being respectively provided with spherical can be to a left side The bias of right direction is adjusted.Bearing 2 mainly acts on articulated shaft 5 when rotating, and becomes its axial location the effect of articulated shaft 5 Change, it is since lower hinge 4 is hinged on articulated shaft 5, then inevitable to be located along the same line with 5 center line of articulated shaft, hinged The center line locking variation of lower hinge 4 is then driven during the center line variation of axis 5, and then realizes the center line to articulated shaft 5 Adjustment and the effect of adjusting of centerline to lower hinge 4.

Realize the center line between upper articulation part 3 and lower hinge 4 in vertical direction deflection by eccentric bushing 1 Adjustment.That is 4 center line decentraction of upper articulation part 3 and lower hinge.Eccentric bushing 1 is set on bearing 2, manually manually Rotating eccentric sleeve 1 can realize the adjustment to eccentric bushing 1, and active force makes axis in the outer circumference surface of bearing 2 when eccentric bushing 1 rotates It holds 2 drives and fits within the articulated shaft 5 in portion and do the linear motion of vertical direction, and then drive the lower part being located on articulated shaft 5 Articulation piece 4 moves up and down, and the center line of lower hinge 4 is made to change up and down and is adjusted, and is finally located at upper articulation part 3 same On one straight line.

Further, the eccentric adjuster is set at least provided with 1 group, can be correspondingly arranged on as needed 2 groups or It is multigroup, it realizes to the eccentric even regulation between upper articulation part 3 and lower hinge 4.

Preferably, the eccentric adjuster in the present embodiment is provided with 2 groups, is symmetricly set on the both ends of the articulated shaft 5. For symmetrically and evenly synchronizing adjustment to 5 both sides of articulated shaft, it is ensured that the accuracy of adjustment and final installation assembly precision.

To realize the sealing to bearing 2, prevent 2 inside of bearing from entering dust, influence the normal use of bearing 2, this implementation Clutch shaft bearing end cap 6 and second bearing end cap 7 are correspondingly arranged at the both ends of bearing 2 in example, eccentric bushing 1 is set on bearing 2 It is fastened on simultaneously between the clutch shaft bearing end cap 6 at both ends and second bearing end cap 7 afterwards, and the corresponding and clutch shaft bearing end cap 6, 7 detachable connection of second bearing end cap.Specifically, the clutch shaft bearing end cap 6 is provided with the first threaded hole 61, described second The second threaded hole 71 is provided on bearing (ball) cover 7, the eccentric bushing 1 is provided at both ends with and 61 and second spiral shell of the first threaded hole The thread fitting hole 11 that pit 71 coordinates, passes through spiral shell between the eccentric bushing 1 and the clutch shaft bearing end cap 6, second bearing end cap 7 Bolt 8 tightens fixation.The 3rd mounting hole 62 is additionally provided on clutch shaft bearing end cap 6, passes through fastening bolt inserting to articulated shaft 5 The interior center with articulated shaft 5 is fixedly connected.

Further, fixation is attached by a fastener 9 and the upper articulation part 3 on the eccentric bushing 1, it is described Fastener 9 is to along the circumferentially disposed of the eccentric bushing 1.It is additionally provided with what is coordinated with the fastener 9 on the eccentric bushing 1 Mounting hole 12, when eccentric bushing 1 is adjusted, it is necessary to which fastener 9 is located at clutch shaft bearing end cap 6 and second bearing end cap with stubborn Bolt 8 on 7 is backed out, and is realized adjustment, is sequentially screwed into again after the completion of adjustment and fastening is fixed.

Preferably, the eccentricity of the eccentric bushing 1 in the present embodiment is 1mm.I.e. corresponding articulated shaft 5 can up and down adjustment model It encloses for 0-1mm.

Further, it is interference fit between the bearing 2 and the articulated shaft 5, between the eccentric bushing 1 and the bearing 2 For clearance fit.

Above example is only to illustrate the technical solution of the utility model rather than is limited；Although with reference to before Embodiment is stated the utility model is described in detail, it for those of ordinary skill in the art, still can be right Technical solution recorded in previous embodiment modifies or carries out equivalent substitution to which part technical characteristic；And these Modifications or substitutions, do not make appropriate technical solution essence depart from the utility model technical solution claimed spirit and Scope.
