Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model is used for centration axis before the centre-drilling hole of axle class knuckle, and in addition, after reserving central shaft, this device can be fixed axle class knuckle workpiece, to carry out follow-up boring work.So-called axle class knuckle comprises body 100, lever arm 200 and axle portion 300.Lever arm 200 horizontally outward extends from body, and lever arm 200 generally comprises torque arm, shock-absorbing arms, clamp etc.Axle portion 300 vertically gives prominence to from body 100.Namely so-called centre-drilling hole bore the duct of a through body in axle portion 300, and this duct is in use for being connected with bearing.
Self-centering device of the present utility model comprises base plate 1, centering sliding bush 2, Compress Spring 3, sliding sleeve base 4, cushion block 5 and workpiece pressing 6.
Base plate 1 is provided with through hole 7, and this through hole 7 size is mated with the axle portion of knuckle, can pass for axle portion.Centering sliding bush 2 is the key components realizing centering.As shown in Figure 1, centering sliding bush 2 is for having the body of inner conical surface, the shape of inner conical surface is mated with axle portion, when this centering sliding bush 2 moves axially to axle portion, suppose that centering sliding bush axle can not occur and departs from, axle portion can be inserted in centering sliding bush, and so the position in axle portion will inevitably adjust automatically, automatically adjusts on the position coaxial with centering sliding bush.
The utility model adopts the mode of driving centering sliding bush 2 axial translation to realize sliding sleeve and axle portion is concentric.Particularly, the peripheral distribution of through hole 7 has column 8, and the quantity of column 8 can be more than 3 groups or 3 groups, and Compress Spring 3 is placed on column 8, and centering sliding bush 2 is slidably fixed on the column above Compress Spring 3.Under the effect of Compress Spring 3, centering sliding bush 2 can outside axial translation.Sliding sleeve base 4 to be fixed on base plate 1 and to arrange outside adjacent centering sliding bush 2, plays the effect supporting centering sliding bush 2 and slide.
The quantity of cushion block 5 is at least three groups, and axle portion is positioned at the region that cushion block order is linked to be.Cushion block 5 is for supporting knuckle entirety, and during use, the lever arm end of knuckle is placed on cushion block 5, and cushion block 5 is between lever arm end and base plate 1, and in the present embodiment, corresponding torque arm, shock-absorbing arms, clamp place are respectively equipped with cushion block.The height of cushion block 5 generally needs to arrange according to the height of lever arm end, and when guaranteeing that knuckle is placed on cushion block, its body is parallel with base plate 1.For the ease of change cushion block, be generally Detachable connection structure between cushion block and base plate 1, in the present embodiment, cushion block by screw lock on base plate.
Workpiece pressing 6, for compressing knuckle, avoids knuckle by centering sliding bush 2 jack-up.
When feeling relieved, knuckle is placed on base plate, and lever arm is placed on cushion block accordingly.The axle portion of knuckle extend in through hole and is compressed by centering sliding bush.After centering sliding bush under the effect of Compress Spring to the translation of axle portion, axle portion can automatic adjusting position under the effect of centering sliding bush, and the central shaft in axle portion is alignd with the center of through hole, realizes feeling relieved.
Convenient in order to make workpiece pressing of the present utility model use, as preferably, workpiece pressing 6 comprises cylinder 9, pull bar 10, pressing plate 11, guide post 12 and support bar 13.Pull bar 10, guide post 12 are vertical with support bar 13 to be fixed on base plate 1, and the bottom of pull bar 10 is connected with cylinder 9, mobile lifting under the driving of cylinder 9.The center order of support bar 13, guide post 12, pull bar 10 and through hole 7 is located on same straight line, and pressing plate 11 is provided with fluting 14, and pressing plate 11 is threaded onto on pull bar 10 by fluting 14, and the top of pull bar 10 is provided with locking nut 15.One end of pressing plate 11 is set to pressure head to compress axle class knuckle, and the other end of pressing plate 11 is set to support end for support bar 13 jack-up, and between support end and fluting 14, the position of corresponding guide post is provided with the pilot hole 16 inserted for guide post 12.The pressure head of pressing plate 11 is provided with U-lag.Workpiece pressing 6 adopts above structure, and pressing plate 11 can move neatly, when not needing to compress, pressing plate 11 being turned to the position of departing from guide post 12 and support bar 13, then being dropped on base plate by pressing plate 11.When needs compress, pressing plate 11 is risen, then under the guide effect of guide post 12, swings on the straight line residing for center of support bar 13, guide post 12, pull bar 10 and through hole 7, make the support end of pressing plate 11 abut on support bar 13, the pressure head of pressing plate 11 can be pressed on knuckle.Because pressure head is provided with U-lag, therefore centre bore to be processed can be avoided by it, guarantees that follow-up boring work can be carried out smoothly.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
