Diminishing halfpace structure.
Preferably, the case is transparent casing.
The utility model has the advantages that：
A kind of adjustment fastener of three coordinate measuring machine of the utility model, it is simple in structure, adjustment fastener is avoided by external force
Effect and can not effectively air supporting block and moving component, then so that air supporting block and granite way rub severity.
Brief 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.
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 adjustment fastener of the utility model three coordinate measuring machine, for connecting air supporting block and moving component.
The adjustment fastener includes the case for holding out against first 1, threaded body portion 2, adjustment part 3 and built-in elastic part 13
4.The back segment portion 12 for holding out against first 1 cephalic par 11 and its diameter of axle including acting on air supporting block and being less than cephalic par.The spiral shell
Through hole 21 is equipped with line main part 2, the through hole 21 divides the through hole 21 to column 22 by the way that two in through hole 21 are symmetrical
For interconnected front cavity 23 and rear chamber 24.The adjustment part 3 such as bolt, symmetrically column 22 is supported from the rear chamber 24 through two
Between space wear into the front cavity 23, stretch into afterwards it is described hold out against first 1 back segment portion 12 and be threadedly coupled with it.The top
The outside in tight first 1 back segment portion 12 and 21 clearance fit of through hole, the described two symmetrical space lengths supported between column 22 are less than institute
State the aperture of through hole 21.The first 1 back segment portion 12 of holding out against is equipped with case 4, when adjustment part 3 acts on 2 phase of threaded body portion
For it is described hold out against first 1 movement when, the threaded body portion 2 can stretch into, stretch out the case 4, and in the work of the adjustment part 3
With acting on the elastic component 13 under direction.Elastic component 13 is arranged in case 4 by the utility model, can avoid elastic component well
The 13 exposed possibility collided outside, and then ensure that aligning effect uniformly, is effectively realized so that possess between guide rail and air supporting block
Protect air film.
The threaded body portion 2 can stretch into, stretch out the part of the case 4, be coordinated with the case 4 in a manner of slide.
Specifically, one of the case 4 or the threaded body portion 2 are equipped with slide, another remaining setting can be on slide
Slide the sliding block of cooperation.When adjustment part 3 adjusts, threaded body portion 2 is driven to extrude elastic component 13, the threaded body portion 2 acts on
The position 25 of the elastic component 13 is slipped into the case 4 and elastic component 13 is extruded, to realize elastic aligning effect.
Fig. 1 shows the structure diagram of embodiment one.The elastic component 13 is sheathed on the back segment portion 12 for holding out against head
Outside.The elastic component 13 is butterfly spring.When adjustment part 3 is bolt, bolt stretches into through hole 21 and the back segment portion with holding out against first 1
12 thread fittings act on the butterfly spring, and elastic aligning effect is realized by elastic component.For useful effect elastic component, the spiral shell
The position 25 that line main part 2 acts on the elastic component 13 holds out against the diminishing halfpace knot in first 1 direction for radial dimension to described
Structure.
Fig. 2 shows the structure diagram of embodiment two.The elastic component 13 be arranged on the back segment portion 12 for holding out against head with
Hold out against first 1 11 junction of cephalic par.When it is adjustable spring that the elastic component, which is 13, after its one end holds out against head described in
Section portion 12 and hold out against first 1 11 junction of cephalic par, the other end is as threaded body portion 2 described in the face of free end.To reduce institute
Threaded body portion 2, the size of case 4 are stated, the case 4 is as small as possible, houses the elastic component 13, while the screw thread just
Main part 2 matches with 4 size of case, and the threaded body portion 2 is acted on the position 25 of the elastic component 13 for radially
Size column structure constant always.When adjustment part 3 is bolt, bolt stretches into through hole 21 and the back segment portion 12 with holding out against first 1
Thread fitting acts on the adjustable spring, and elastic aligning effect is realized by elastic component.
In order to make 3 firm effect of adjustment part symmetrically support column 22 and the adjustment part 3 in the back segment portion 12 for holding out against head, two
Thread fitting.When through hole is stretched into adjustment part rotation, threaded tightening force provides active force for compression elastic piece, then so that manpower
Adjust more effortless.
First 1 cephalic par 11 of holding out against to be round table-like, round platform can stepless action on air supporting block.
For ease of checking adjustment part, whether useful effect is when the elastic component 13, the case 4 can be arranged to transparent casing.
In this way, can be easy to check whether elastic component 13 there are significantly uneven stressing conditions, then replace, adjust elastic component.
Opening is equipped with 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.
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
Expose outside and easily collide 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 the utility model shown in foregoing description and attached drawing is only used as
Illustrate and be 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.
