The invention relates to a vacuum
induction brazing device and a use method thereof. The device comprises a rotating motor, a rotating motor fixed plate, a supporting rod A, magnetofluid, a workpieceA, a
vacuum chamber, a lifting adjusting plate, a guide rod, a lifting motor fixed plate, a lifting motor, a lifting nut, a screw, a
welding corrugated
pipe, an
induction coil, a workpiece B, a rotating sample table and a supporting rod B, the rotating motor is fixedly mounted on the bottom face of the rotating motor fixed plate, the top face of the rotating motor fixed plate is connected with themagnetofluid through the supporting rod A and the supporting rod B which are arranged in parallel, the magnetofluid is fixed to the bottom of the
vacuum chamber, the rotating sample table is fixed toa magnetofluid shaft and is located in the
vacuum chamber, the screw is in transmission connection with an output shaft of the lifting motor, the
induction coil is fixedly connected with the liftingadjusting plate and is located in the vacuum chamber, the device has the advantages of being reasonable in structural design, convenient to operate and use, and low in running cost, vacuum
brazing andinduction
brazing advantages are combined, defects of vacuum
brazing and
induction brazing are overcome, and workpiece rapid
pollution-free
welding is achieved.
