Base is the individual layer triangle platform that single angle is welded, and is fixed by foundation bolt and ground, three root posts
Lower end is vertically connected on base, and three root post upper ends are welded into frame, column inner side with triangle top plate of the center containing circular hole
Equipped with leading screw, a screw servomotor is set at the top of every leading screw, three leading screws are in sustained height position by sliding up and down
Block connects arc orbit, and three leading screws up pass through triangle flat plate, can freely control circular arc rail by leading screw servomotor
Road oscilaltion, sets a rotary slider on arc orbit, is provided with laser displacement sensor and track servo motor thereon, leads to
Cross track servo motor control rotary slider and clamp the bottom holding claw of test specimen around circular motion, base top surface configuration.Two bottoms
Portion's holding claw is connected with being fixed on the horizontal air cylinder of base top surface, and horizontal air cylinder provides power by the air compressor machine for being placed on ground.
Treat that geodesic structure is placed on base center during use, clamped by bottom holding claw.
Bottom holding claw supplies power to horizontal air cylinder by air compressor machine and clamps, and the data of laser displacement sensor pass through test
System acquisition and analysis.
It is a further object to provide application of the described device in contactless body structure surface shape is measured.
The beneficial effects of the invention are as follows：Servomotor can accurately control positioning by digit pulse model, rotary speed and
Angle is all easily controlled；Servomotor can produce very high control when stopping and reverse, it is not necessary to be stopped using machinery；Laser position
