Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, and
It is not used in the restriction present invention.
The present invention is used for centration axis before countershaft class knuckle centre-drilling hole, in addition, reserve this device after central shaft can be right
Axle class knuckle workpiece is fixed, to carry out follow-up boring work.So-called axle class knuckle includes body 100, bar
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 projects from body 100.The duct of an insertion body, this duct are bored in so-called centre-drilling hole in axle portion 300
When using for being connected with bearing.
The Self-centering device of the present invention includes base plate 1, centering sliding bush 2, compression spring 3, sliding sleeve base 4, cushion block 5 and pressure
Clamping of workpieces 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 through for axle portion.Centering is slided
Set 2 is the key component realizing centering.As shown in figure 1, centering sliding bush 2 is to have the body of inner conical surface, the shape of inner conical surface with
Axle portion is mated, when this centering sliding bush 2 moves axially to axle portion it is assumed that centering sliding bush will not occur axle to deviate, axle portion to be made
Can be inserted in centering sliding bush, then the position of axle portion will necessarily be adjusted automatically, be automatically adjusted to coaxial with centering sliding bush
Position on.
The present invention realizes sliding sleeve by the way of driving centering sliding bush 2 axial translation and axle portion is concentric.Specifically, lead to
The peripheral distribution in hole 7 has column 8, and the quantity of column 8 can be 3 groups or more than 3 groups, and compression spring 3 is placed on column 8, centering
Sliding sleeve 2 is slidably fixed on the column of compression spring 3 top.In the presence of compression spring 3, centering sliding bush 2 can be to outer shaft
To translation.Sliding sleeve base 4 is fixed on base plate 1 and adjacent centering sliding bush 2 outside arrangement, plays and supports centering sliding bush 2 to slide
Effect.
The quantity of cushion block 5 is at least three groups, and axle portion is in the region that cushion block order is linked to be.Cushion block 5 is used for knuckle
Entirety is supported, and during use, the lever arm end of knuckle is placed on cushion block 5, and cushion block 5 is located between lever arm end and base plate 1,
In the present embodiment, corresponding torque arm, shock-absorbing arms, be respectively equipped with cushion block at clamp.The height of cushion block 5 generally requires according to lever end
The height in portion be configured it is ensured that when knuckle is placed on cushion block its body parallel with base plate 1.For the ease of changing cushion block, pad
It is generally Detachable connection structure, in the present embodiment, cushion block passes through screw lock on base plate between block and base plate 1.
Workpiece pressing 6 is used for compressing knuckle, it is to avoid knuckle is by centering sliding bush 2 jack-up.
When being felt relieved, knuckle is placed on base plate, and lever arm is accordingly placed on cushion block.The axle portion of knuckle extend into logical
Centering sliding bush is compressed by the hole.Translate to axle portion in the presence of compression spring after centering sliding bush, axle portion is in centering sliding bush
Effect lower meeting automatic adjusting position, so that the central shaft of axle portion and the center alignment of through hole, realizes centering.
So that the workpiece pressing of the present invention is using convenient, preferably, workpiece pressing 6 includes cylinder 9, pull bar
10th, pressing plate 11, guide post 12 and support bar 13.Pull bar 10, guide post 12 and support bar 13 are perpendicularly fixed on base plate 1, draw
The bottom of bar 10 is connected with cylinder 9, mobile lifting under the driving of cylinder 9.Support bar 13, guide post 12, pull bar 10 and logical
On same straight line, pressing plate 11 is provided with fluting 14 to the center order in hole 7, and pressing plate 11 passes through fluting 14 and is threaded onto pull bar 10
On, the top of pull bar 10 is provided with locking nut 15.One end of pressing plate 11 is set to pressure head and is compressed with countershaft class knuckle, pressing plate 11
The other end is set to support end for support bar 13 jack-up, is provided with for leading between support end and fluting 14 at the position of corresponding guide post
Pilot hole 16 to bar 12 insertion.The pressure head of pressing plate 11 is provided with U-lag.Workpiece pressing 6 adopts above structure, and pressing plate 11 can spirit
Move alively, when being not required to compression, pressing plate 11 is turned to and deviates at the position of guide post 12 and support bar 13, then will
Pressing plate 11 drops on base plate.When needing compression, pressing plate 11 is risen, then under the guide effect of guide post 12,
Swing on the straight line residing for support bar 13, the center of guide post 12, pull bar 10 and through hole 7 so that 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 it can be by institute
Centre bore to be processed is avoided it is ensured that follow-up boring work can be smoothed out.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
