Embodiment
As shown in Fig. 1, Fig. 2, this is currently used support pole, but the pole is set for the support of external balance
Meter, therefore the branch fastener of pole is supported using square structure, but the structure cannot be supported to internal balance.
It is the support pole that the present invention designs as shown in Figure 3, upper end is using U-shaped structure, lower end and existing structure
Equally.And cylinder pin hole is set on two vertical edges of U-shaped structure, for being fixedly connected.
As shown in figure 4, being the transition piece that the present invention designs, this is one of emphasis of the present invention, is using the design
In order to coordinate U-shaped structure, transition piece uses tubular construction, and an end face opening, another end face is designed to flange arrangement；
Cylinder pin hole is respectively arranged with two vertical sides of transition piece, plays fixation.Transition piece is close to flange
Screwed hole is respectively arranged with the upper and lower surface of structure one end, for connecting tail joint.
As described in Figure 5, for the structure of single-point support mode, method one end of internal balance being fixed in transition piece
In blue structure, the tested model of other end connection of internal balance.Then transition piece is fixed on U-shaped structure with straight pin
In vertical edge so that transition piece can be swung up and down in U-shaped structure.Consolidated on the lower surface of transition piece by screw thread
Surely a tail joint is connected, then connects as one support sting with tail joint by way of straight pin.Support sting it is another
End is connected on the driving pole of drive mechanism, is hollow structure typically by support pole indoor design to save space, and
Breach is opened up in side vertical direction, the driving pole of drive mechanism is arranged in support pole, support sting passes through support branch
The breach in bar side face is connected with driving pole.Such design so that drive mechanism drives driving pole to transport up and down at work
Dynamic, so as to drive support sting to move, formed an angle setting between support sting and driving pole, therefore support sting one end is transported up and down
When dynamic, the other end will drive transition piece to be swung up and down in U-shaped structure, so as to carry out the change to being tested model attitude angle
Change.
When needing to use 2 supporting way, it is only necessary to remove support sting, connection pole is connected into tested model
Endpiece so that connection pole and internal balance keep coaxial position, and the other end for connecting pole is connected to driving structure i.e.
Can.
Above-mentioned described implementation is directed to internal balance, and the device designed certainly using the present invention can also use outer formula
Balance.In the case of integral layout is immovable, whole support meanss are arranged on external balance and tested.Single-point
Supporting way and 2 supporting way all use above-mentioned structure.
The invention is not limited in foregoing embodiment.The present invention, which expands to, any in this manual to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
