Fixed vertical direction actuator simultaneously drives vertical direction actuator to move left and right；The horizontal direction actuator fixing device is used for
Fixed horizontal direction actuator, and in the presence of the 3rd adjusting screw horizontal direction actuator can be driven to make vertical direction
Movement.
The vertical direction actuator fixing device is bolted on crossbeam by two groups, real by unclamping two groups of bolts
Existing vertical direction actuator fixing device is moved left and right along crossbeam.
Altitude location hole is respectively equipped with the left longeron and right vertical beam, the crossbeam is bolted to left vertical by two groups
On beam and right vertical beam, by adjusting the first adjusting screw and the second adjusting screw after unclamping two groups of bolts, realize that crossbeam is indulged along left
Beam and right vertical beam are moved up and down.
3rd adjusting screw and horizontal direction actuator fixing device are correspondingly arranged at the inner side of left longeron, and water
Square slide and to be connected to actuator fixing device and left longeron.
The horizontal direction actuator fixing device is bolted on left longeron by two groups, by unclamping two groups of bolts
The 3rd adjusting screw is adjusted afterwards, realizes that horizontal direction actuator fixing device is moved up and down along left longeron.
Compared with prior art, the present invention has advantages below；
First, it is easy to operate：Various model gas extraction system test samples can be adapted to by adjusting each leading screw, and operated light
Just, it is time saving and energy saving.
2nd, effect is obvious：By improving mounting means, the rigidity and mode of whole testboard bay are improved, examination is improved
Test frequency and control accuracy are tested, so as to improve the test capability of stand.
3rd, technique is simple：The feed screw apparatus and rapidoprint used in fixture is easily bought, easy for installation.
