Because the schedule requirement of workpiece is higher, workpiece can be because be jacked up by small iron filings sometimes, and occurs small askew
Tiltedly, but by naked eyes it is difficult judge small crooked of workpiece, therefore detection hole is provided with preferably on clamping jaw；When fixture is completed
After the positioning of workpiece, the lower surface of workpiece will block detection hole completely, then pressure gauge is up to preset value, if workpiece is pressing from both sides
Occur crooked during tight, then the lower surface of workpiece will be unable to block detection hole completely, so as to pressure gauge be then unable to reach it is pre-
If value, it is necessary to clamped again to workpiece.In this is preferred, when workpiece blocks detection hole, tracheae is completely enclosed, then
Pressure-control valve can control endotracheal pressure not over preset value, so as to damage tracheae.
