It states guide post to be set between pedestal and top plate in cruciform symmetry, is equipped with guide rail on the guide post vertically, is embedded with and stretches in the guide rail
Contracting support rod, the end of the telescopic supporting rod are hinged with clamping wheel, are radially equipped with probe aperture, the spy on the clamping wheel
Flexible coordinate probe is equipped in pin hole, the flexible coordinate probe and coordinate probe are electrically connected with the data processor.
Preferably, driving motor is equipped between the telescopic supporting rod and clamping wheel, the driving motor drives clamping
Wheel rotation.
Preferably, housing is equipped between the pedestal and top plate, one end of the housing is fixed on the outer surface of pedestal
On, the other end is fixed on the outer surface of top plate.
Preferably, dismountable thimble is symmetrically arranged at the center of the pedestal and top plate.
The utility model has the beneficial effect that the scan arm pair by moving along ring-shaped guide rail compared with prior art
Object under test detect circulating type circular scanning, while using four rolling clamping wheels along above and below guide post relative motion realize to
The overturning for surveying object carries out data acquisitions using the more clamping wheel retaining parts of flexible coordinate probe in probe aperture on clamping wheel,
Avoid acquisition blind area.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 is pedestal, and 2 be top plate, and 3 be guide post, and 4 be telescopic supporting rod, and 5 be clamping wheel, and 6 be probe aperture, and 7 be to sweep
Arm is retouched, 8 pop one's head in for coordinate.
Specific embodiment
As shown in Figure 1, at the utility model a kind of three-dimensional coordinate building instrument, including pedestal 1, top plate 2, guide post 3 and data
Device is managed, the bottom plate 1 and top plate 2 are equipped with ring-shaped guide rail, are embedded with scan arm 7 in the ring-shaped guide rail, the scan arm 7 can
It is slided along the ring-shaped guide rail, is equipped with multiple coordinates probe 8 on the scan arm 7 vertically, the guide post 3 is set in cruciform symmetry
Between pedestal 1 and top plate 2, guide rail is equipped on the guide post 3 vertically, telescopic supporting rod 4 is embedded in the guide rail, it is described to stretch
The end of contracting support rod 4 is hinged with clamping wheel 5, and driving motor, the driving electricity are equipped between telescopic supporting rod 4 and clamping wheel 5
Machine drives clamping wheel 5 to rotate.It is radially equipped with probe aperture 6 on the clamping wheel 5, flexible coordinate is equipped in the probe aperture 6 and is visited
Head, the flexible coordinate probe and coordinate, which are popped one's head in, 8 to be electrically connected with the data processor, by data processor by flexible seat
The three-dimensional coordinate for the testee that mark probe and coordinate probe 8 are collected into carries out processing conversion and forms threedimensional model.In order to enhance
The stability of the clamping object of three-dimensional coordinate building instrument is symmetrically arranged with dismountable thimble at the center of pedestal 1 and top plate 2, leads to
Cross the object clamped needed for thimble Auxiliary support.In order to improve the detection accuracy of instrument, guarantee detecting instrument under vacuum conditions
Carrying out work avoids the surface of object under test from falling into dust, and housing, one end of the housing are equipped between pedestal 1 and top plate 2
It is fixed on the outer surface of pedestal 1, the other end is fixed on the outer surface of top plate 2, vacuum pump is additionally provided on top plate 2, by true
Sky pump and housing enable instrument internal keep vacuum.
When work, by object under test as between the guide post 3 in cruciform symmetry setting, all telescopic supporting rods 4 are along guide post 3
