Spring, the adjustment part act on the elastic component.
Preferably, the diameter of axle of the diameter of axle in the threaded body portion no more than the cephalic par for holding out against head.
Preferably, two symmetrically support column and the adjustment part thread fitting.
Preferably, the cephalic par for holding out against head is round table-like.
The utility model has the advantages that：
A kind of adjustable fastener for three coordinate measuring machine of the utility model, it is simple in structure, avoid adjustment fastener by
External force act on and can not effectively air supporting block and moving component, then so that air supporting block and granite way rub severity.
Description of the drawings
Fig. 1 is a kind of structure diagram of the adjustment fastener embodiment one of three coordinate measuring machine of the utility model；
Fig. 2 is a kind of structure diagram of the adjustment fastener embodiment two of three coordinate measuring machine of the utility model.
Specific embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
Such as Fig. 1-2, the utility model is used for the adjustable fastener of three coordinate measuring machine, for connecting air supporting block and movement portion
Part.
The adjustment fastener includes holding out against first 1, threaded body portion 2, adjustment part 3.The head that holds out against includes acting on institute
It states the cephalic par 11 of air supporting block and its diameter of axle is less than the back segment portion 12 of cephalic par 11.Through hole is equipped in the threaded body portion 2
21, the through hole 21 is divided the through hole 21 for interconnected front cavity 23 by be arranged in through hole 21 the two symmetrical columns 22 that support
With rear chamber 24.The adjustment part 3 such as bolt, is worn from the rear chamber 24 through the two symmetrical spaces between column 22 into institute
State front cavity 23, stretch into afterwards it is described hold out against first 1 back segment portion 12 and be threadedly coupled with it.It is described hold out against first 1 back segment portion 12
Outside and 21 clearance fit of through hole.The described two symmetrical space lengths between column 22 are less than the aperture of the through hole 21.
Elastic component 13 is equipped in the built-in space for holding out against first 1 back segment portion 12 and being stretched into the adjustment part 3.When adjustment part 3 stretches into
The through hole 21, then act on it is described hold out against first 1 back segment portion, air supporting block and moving component are connected in a manner of adjusting center
It connects.Because holding out against first 1 built-in space described in elastic component 13 is arranged on, the exposed possibility collided outside of elastic component 13 is avoided,
And then ensure that aligning effect uniformly, is effectively realized so that possess protection air film between guide rail and air supporting block.
Fig. 1 shows the structure diagram of embodiment one.The elastic component 13 is the back segment that one end holds out against first 1 described in
The adjustable spring of 12 built-in space bottom of portion, adjustment part 3 described in the other end face of the elastic component 13.When adjustment part 3 is spiral shell
During bolt, bolt stretches into through hole 21 and the free end of the adjustable spring is acted on holding out against first 1 back segment portion thread fitting, passes through bullet
Property part realize elastic aligning effect.
Fig. 2 shows the structure diagram of embodiment two.The elastic component 12 is arranged on the back segment portion 12 for holding out against head
The butterfly adjustable spring of built-in space side, the adjustment part 3 act on the elastic component 13.As it can be seen that the adjustment part has in figure
There are front end service portion 31 and back segment thread fiting part 32, the front end service portion 31 can carry out the butterfly adjustable spring
It squeezes, the back segment thread fiting part 32 holds out against 12 thread fitting of back segment portion with described.Wherein, the front end service portion 31 is
The diameter of axle is less than the diameter of axle of the back segment thread fiting part 32.Through hole 21 is stretched into adjusting the adjustment part 3, and then is held out against with described
During 12 thread fitting of back segment portion of head, the front end service portion 31 squeezes elastic component 13, realizes aligning effect.
In order to which 3 firm effect of adjustment part is made to hold out against a back segment portion 12 in described, two symmetrically support column 22 and 3 spiral shell of adjustment part
Line coordinates.When through hole is stretched into adjustment part rotation, threaded tightening force provides active force for compression elastic piece, then so that manpower tune
It is whole more effortless.
In order to reduce fastener specification and cost, the diameter of axle in the threaded body portion 2 holds out against first 1 head end no more than described in
The diameter of axle in portion 11.
Opening is equipped in the rear end in the threaded body portion 2, the opening is communicated with through hole 21.Construction personnel can pass through by
Instrument is adjusted after being stretched into from this opening.
First 1 cephalic par 11 of holding out against to be round table-like, round platform can stepless action on air supporting block.
When gas enters air supporting block, there is certain interval between granite guide rail and air supporting block.Hold out against head and threaded body
Clearance fit, and built-in elastic part is utilized, make adjustable fastener that there is certain elasticity and aligning function, and avoid elastic component because naked
It exposes outside and easily collides so that aligning function is not allowed, and then prevents air supporting block from grinding away with granite guide rail.
It should be understood by those skilled in the art that the embodiment of foregoing description and attached the utility model shown in figure is only used as
It illustrates and is not intended to limit the utility model.The purpose of this utility model completely effectively realizes.The function of the utility model
And structural principle shows and illustrates in embodiment, under without departing from the principle, the embodiment of the utility model can
To have any deformation or modification.
