The present application discloses a flexible clamping device. A sleeve is fixed on a base, an adjusting shaft is connected with a mandrel and the sleeve respectively, the mandrel is fixed on the upper end face of the adjusting shaft, and the bottom outer wall of the adjusting shaft is in small clearance fit with the inner wall of the sleeve; a lock screw is installed on the upper right side wall of the sleeve, a pinion is installed on the upper left side wall of the sleeve via a rotating shaft, saw teeth are provided on the side wall of a adjusting shaft, and the pinion can be engaged with the side teeth of the adjusting shaft.

Flexible clamping device

The present invention includes an on-line wheel transfer mechanism. A cylinder, bearing seats and a linear guide rail are mounted on a base. A rack is connected to the linear guide rail through a guide rail seat, an output shaft of the cylinder is connected to the rack, and a rotating shaft A is mounted on the two symmetrical bearing seats. A gear and two rotating arms A are fixed on the rotating shaft A. The rack is engaged with the gear, a rotating shaft B is mounted on two symmetrical bearing seats B, two rotating arms B are fixed on the rotating shaft B, the rotating arms A are hinged to brackets through a rotating shaft C, and the rotating arms B are hinged to the brackets through a rotating shaft D. The rotating shafts constitute a parallelogram hinge four-bar mechanism.

On-line wheel transfer mechanism

The present disclosure provides a low-pressure cast aluminum wheel mold. The back cavity of a top mold () is divided into three parts: the back cavity in a rim area is open, and the wall thickness of the top mold is progressively increased by 15-25 mm from bottom to top; the back cavity in a spoke area is machined in a profile-followed manner, and the top mold has an equal wall thickness of 20-30 mm; at each R angle position where the rim is connected with a spoke, the top mold is provided with a boss (), the axial wall thickness of the boss () is 40-60 mm, and the radial wall thickness is 30-50 mm. A temperature gradient beneficial to progressive solidification of a casting is constructed; by designing an annular water cooling structure at the R angle where the rim is connected with the spoke, quick cooling on the hot spot is specifically realized, the cooling capability is stronger, the cooling range is more exact, bad influence on the adjacent thin-wall part is not produced, and smooth feeding of molten aluminum is ensured.
