Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
A kind of high-power transmitter pneumatic means is present embodiments provided, cavity high frequency is matched suitable for broadcast transmitter
Power source etc. needs the field of high-power electrical contact.As shown in Figure 1 to Figure 3, the pneumatic means includes pressing plate 1, and driving pressing plate 1 moves
Dynamic cylinder 2, and the fixed seat 3 of the cylinder body of cylinder 2 is fixedly arranged on, the fixed seat 3 is provided with the shifting axle positioned at the both ends of cylinder 2
4；One end of the shifting axle 4, which is slided, runs through fixed seat 3, and its other end is connected to pressing plate 1, and it is close to one end of fixed seat 3
It is arranged with compression spring 5, the described one end of pressing plate 1 away from cylinder 2 is sequentially provided with contact point structure 6 and for by contact point structure 6
Deflection maintains the press strip 7 in regime of elastic deformation.
Compression spring 5 causes contact point structure 6 to contact the outer surface of workpiece to the pneumatic means always, is needing pneumatic means
, it is necessary to when first contact point structure 6 not being contacted into workpiece when contacting another position of workpiece, the work of cylinder 2 makes its piston rod 21 upward
Retraction, pressing plate 1 is set to drive contact point structure 6 away from workpiece, while pressing plate 1 will drive shifting axle 4 to move up to press compression spring 5
Contracting；Then the location of workpiece is adjusted, drives shifting axle 4 to move downward in the presence of compression spring 5, shifting axle 4 will drive pressing plate 1
Moving downward makes contact point structure 6 close and contacts workpiece, while pressing plate 1 pulls on the piston rod 21 of cylinder 2 and extended downwardly from, and passes through
The buffering contact point structure 6 of cylinder 2 is close and contacts the speed of workpiece, avoids contact point structure 6 from being caused with larger speed contact workpiece
Workpiece damage；After contacting workpiece compression will occur for contact point structure 6, as contact point structure 6 is close constantly to workpiece, contact knot
The deflection of structure 6 will become larger, but due to the outer surface of workpiece there may be it is uneven, by there is provided press strip 7, therefore
After press strip 7 contacts workpiece, contact point structure 6 will no longer be deformed, and the deflection of contact point structure 6 is maintained into elastic change
In the range of shape, avoid contact point structure 6 from running into boss and produce expendable deformation damage.
