It is dynamic, change the measurement direction of testee；
Main pinching end that three-dimensional clamp system is connected by transmission mechanism and respectively with transmission mechanism, two clamping sides ends are constituted,
Adjusting screw is respectively equipped with each clamping sides end, to improve the position stability of testee.
Further, limit switch and block are provided with clutch plate, rotating mechanism is realized by block and limit switch
Direction positioning.
The rotating mechanism is indexing cam mechanism, realizes the multi-direction measurement to testee.
The locating surface of the main pinching end in the three-dimensional clamp system is cambered surface, and face shape is clamped to adapt to different testees
Shape situation of change.
The locating surface at the clamping sides end is coarse cambered surface, to increase the frictional force of clamping sides.
The transmission mechanism is screw-drive mechanism, including power transmission shaft, rocking bar, nut and tooth bar, rocking bar pass through power transmission shaft
It is connected with main pinching end, nut is connected with tooth bar, drives power transmission shaft to rotate by rocking bar, and drive nut to rotate, using tooth bar
Nut is converted into the movement to clamping sides end.
The working method of this clamping device：Before testee clamping, it is necessary to by clamp system region adjust to want
The testee size of clamping is similar, and then testee is placed on three supporting surfaces of pinching end composition, realizes measured object
The three-point fix of the main locating surface of body, finally carries out clamping.
It is an advantage of the invention that：Can be the object reality of curved surface to two locating surfaces or locating surface of the mutual out of plumb in side
Luggage press from both sides and rotate, be capable of achieving clamped one time, can switch in multiple measurement directions, and meet the precision in all directions want
Ask, the clamping device simple structure, manufacture is easier to, pinching action is rapid and operating method, there are enough clamping stroke and dresses
Unload the space of workpiece.

Specific embodiment
Embodiment：
Reference picture 1, a kind of clamping device, including rotating mechanism and 4 two parts of three-dimensional clamp system.The rotating mechanism is by
One rotating mechanism 1 and the second rotating mechanism 2 are in series.The three-dimensional clamp system 4 is by main pinching end 4-2, clamping sides end
4-4 and transmission mechanism 5 are constituted.
As shown in Fig. 2 in rotating mechanism, motor 1-2 is placed on electric machine support 1-1, motor 1-2 is by connection for rotating mechanism
Axle device 1-3 and input shaft 1-4 band moving cams 1-9 is rotated, and cam 1-9 is rotated and driven clutch plate 1-6 motions so as to change measured object
The measurement direction of body 3.Block 1-7, output shaft 1-8 and limit switch 1-5 are respectively equipped with clutch plate 1-6, by block 1-7
The direction for realizing rotating mechanism with limit switch 1-5 positions.
The main pinching end 4-2 of three-dimensional clamp system is adapted to as shown in figure 3, the clamping face of main pinching end 4-2 is cambered surface
Different testees 3 clamp the situation of change of face shape, and main pinching end supporting surface 4-5 is used to carry out clamping to testee 3
When, with the clamping sides end supporting surface 4-6 of other both directions together as the main locating surface 4-3 of testee 3.
After the clamping sides end 4-4 of three-dimensional clamp system is as shown in figure 4, main locating surface determines, the clamp system of design
Clamping sides end 4-4 must adapt to the change of the angle between the positioning of the side of testee 3, so being used using adjusting screw 4-1
In Auxiliary support, to improve the position stability of testee 3.The supporting surface 4-6 of clamping sides end 4-4 is processed into coarse table
