The cylindrical forgings still need to be clamped again, and the angle adjustment effect is poor. Utility Model Content

[0026] Specifically, multiple rollers 209 move with the slider 2 to clamp the cylindrical casting toward the middle. By rotating the rollers 209, the rollers 209 push the cylindrical casting to rotate, adjust the angle of the cylindrical casting, and expose the clamping position. Example

[0027] like Figure 1-2 As shown, in this embodiment, a transmission shaft 107 is rotatably connected to one side of the support leg 106, and the transmission shaft 107 passes through the surface of one side of the support leg 106, and a bevel gear 108 is fixedly installed on the lower surface of the rotating plate 103 and one end of the transmission shaft 107, and the two bevel gears 108 are movably meshed and connected; a plurality of arc grooves 104 are equidistantly provided on the upper surface of the rotating plate 103, and a push rod 201 is fixedly installed on the lower surface of the slider 2, and the push rod 201 passes through the slide groove 105 and is slidably connected to the arc groove 104.

When fixing the cylindrical forging, the No. 2 fastening bolt 304 is turned to press against the cross plate 3, increase the friction between the rotating shaft 301 and the cross plate 3, and fix the two, so that the adjacent rollers 209 are fixed, and the rollers 209 are prevented from rotating and driving the cylindrical forging to rotate, thereby improving the firmness of the cylindrical forging when clamping.
