The through hole is symmetrically divided into interconnected front cavity and rear chamber to post in two in through hole；The adjustment part is after described
Cavity worn through the two symmetrical spaces to intercolumniation into the front cavity, stretch into afterwards the back segment portion for holding out against head and with its screw thread
Connection；The outside in the back segment portion for holding out against head coordinates with the via clearance；The described two symmetrical space lengths to intercolumniation are small
In the aperture of the through hole；The back segment portion for holding out against head is provided with case, when adjustment part act on the threaded body portion relative to
Described when holding out against head motion, the threaded body portion can stretch into, stretch out the case, and under the action direction of the adjustment part
Act on the elastic component.
Preferably, the threaded body portion can stretch into, stretch out the part of the case, with the case in a manner of slide rail
Coordinate.
Preferably, two symmetrically support post and adjustment part screw thread cooperation.
Preferably, the elastic component is sheathed on described hold out against outside the back segment portion of head.
Preferably, the elastic component holds out against a back segment described in and holds out against the cephalic par junction of head.
Preferably, the position that the threaded body portion acts on the elastic component is radial dimension column knot constant always
Structure.
Preferably, the position that the threaded body portion acts on the elastic component holds out against a direction for radial dimension to described
Diminishing halfpace structure.
Preferably, the case is transparent casing.
The invention has the advantages that：
A kind of adjustment fastener of three coordinate measuring machine of the present invention, it is simple in construction, avoid adjustment fastener from being acted on and nothing by external force

Brief description of the drawings
Fig. 1 is a kind of structural representation of the adjustment fastener embodiment one of three coordinate measuring machine of the present invention；
Fig. 2 is a kind of structural representation of the adjustment fastener embodiment two of three coordinate measuring machine of the present invention.
Embodiment
It is the specific embodiment of the present invention and with reference to accompanying drawing below, technical scheme is further described,
But the present invention is not limited to these embodiments.
Such as Fig. 1-2, the adjustment fastener of three coordinate measuring machine of the present invention, 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 provided with line main part 2, the through hole 21 divides the through hole 21 to post 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 post 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 coordinates with the gap of through hole 21, and the described two symmetrical space lengths supported between post 22 are less than institute
State the aperture of through hole 21.The first 1 back segment portion 12 of holding out against is provided with case 4, when adjustment part 3 acts on the phase of threaded body portion 2
For it is described hold out against first 1 motion 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 in case 4, it is naked can be avoided elastic component 13 well by the present invention
Expose outside the possibility collided, and then ensures that aligning effect uniformly, is effectively realized so that possesses protection between guide rail and air supporting block
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 rail.
Specifically, one of the case 4 or the threaded body portion 2 are provided with slide rail, and another remaining setting can be on slide rail
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 structural representation 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
Butterfly spring described in 12 screw thread mating reactions, 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 structural representation of embodiment two.The elastic component 13 located at the back segment portion 12 for holding out against head with
Hold out against first 1 junction of cephalic par 11.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 the junction of cephalic par 11, 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 the size of case 4, and the threaded body portion 2 is acted on into 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
Adjustable spring described in screw thread mating reaction, elastic aligning effect is realized by elastic component.
In order that the firm effect of adjustment part 3 symmetrically supports post 22 and the adjustment part 3 in the back segment portion 12 for holding out against head, two
Screw thread coordinates.When through hole is stretched into adjustment part rotation, threaded tightening force provides active force for compression elastic piece, then causes manpower
Adjustment is more laborsaving.
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 into transparent casing.
So, it can be easy to check whether elastic component 13 has significantly uneven stressing conditions, then change, adjust elastic component.
Opening is provided with the rear end in the threaded body portion 2, the opening communicates with through hole 21.Workmen 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
Gap coordinates, and utilizes built-in elastic part, adjustable fastener is had certain elasticity and aligning function, and avoid elastic component because naked
Expose outside and easily collide so that aligning function is forbidden, and then prevents air supporting block from being ground away with granite guide rail.
It should be understood by those skilled in the art that the embodiments of the invention shown in foregoing description and accompanying drawing are only used as illustrating
And it is not intended to limit the present invention.The purpose of the present invention completely effectively realizes.The function and structural principle of the present invention is in reality
Apply and show and illustrate in example, under without departing from the principle, embodiments of the present invention can have any deformation or modification.
