The utility model discloses an automatic feeding turnover mechanism for
cold saw machining, and relates to the technical field of
cold saw machining, the automatic feeding turnover mechanism comprises a
machining box, a supporting frame and a saw blade, a turnover table is rotatably installed in the supporting frame, at least two positioning sliding plates are installed on the surface of the turnover table in a sliding mode, a
lantern ring is fixedly installed at the side end of the turnover table, and the positioning sliding plates are fixedly installed on the
lantern ring. By rotating the overturning table, the overturning table drives the
lantern ring to rotate together, rotation of the lantern ring extrudes the
tail end of the positioning block, the
tail end of the positioning block is in an arc design, the positioning block moves upwards under
extrusion, the two telescopic rods are extruded to stretch out and draw back, the positioning block leaves the interior of the lantern ring,
extrusion of the positioning block is avoided, and the pressing plate resets upwards. Meanwhile, the positioning sliding plate is driven to stretch out and draw back reversely, the positioning sliding plate is driven to move towards one side of the lantern ring, the distance between the positioning sliding plate and the auxiliary plate is increased, the lantern ring can control movement of the positioning sliding plate, the rotating angle of the overturning table is limited through the lantern ring, and the stabilizing effect is achieved.
