[0015] Compared with the prior art, the utility model provides a cylinder buckling mechanism, which has the following beneficial effects:

[0016] 1. Through the setting of the cam disc inner shaft, the cylinder inner shaft, the fixed seat inner shaft, the connecting shaft inner shaft, the side wall rotating shaft inner shaft, and the connecting block inner shaft, first, the cylinder inner shaft is fixedly installed through the fixed seat inner shaft. When the cylinder inner shaft moves, the cylinder inner shafts on both sides will push the connecting shaft inner shaft to move. Since the connecting shaft inner shaft and the connecting block inner shaft are movably connected through the rotating shaft inner shaft, the connecting block inner shafts on both sides are pushed to drive the cam disc inner shaft to rotate. Through the setting of the roller inner shaft and the sliding block inner shaft, when the cam disc inner shaft rotates, the cam disc inner shaft and the roller inner shaft are gradually tangent. The roller inner shaft is moved inward by the pressure of the cam disc inner shaft, and then pushes the sliding block inner shaft to move inward. Through the setting of the limit block inner shaft, the spring inner shaft, and the pressure head inner shaft, due to the sliding The inner shaft of the block is fixedly connected with the inner shaft of the limit block. When the inner shaft of the sliding block moves inward, it will drive the inner shaft of the limit block below to move inward, thereby compressing the inner shaft of the spring inner shaft. The movement of the inner shaft of the sliding block will also push the inner shaft of the pressure head to move inward, and the inner shaft of the pressure head will press the cylindrical workpiece. When the pressing is completed, the inner shaft of the oil cylinder is retracted. At this time, the inner shaft of the cam plate is driven by the inner shafts of the connecting blocks on both sides to rotate in the opposite direction, thereby reducing the pressure on the inner shaft of the roller inner shaft. The inner shaft of the spring inner shaft pushes the inner shaft of the limit block and the inner shaft of the sliding block above to move outward due to the restoring elastic force, thereby releasing the pressing of the inner shaft of the pressure block on the cylindrical workpiece. This mechanism is used for cylindrical products, pressing from the outside to the inside, compressing the cylinder, and making the cylinder buckle on an inner ring, so that the position of the cylinder and the inner ring remains fixed after buckling, thereby ensuring the pressing quality of the cylindrical workpiece.

[0017] 2. Through the setting of the inner shaft-inner shaft and the plugging of the inner shaft-inner shaft with the inner shaft of the limit block, the inner shaft of the limit block can move on the inner shaft-inner shaft, ensuring that the position of the inner shaft of the limit block will not be offset, so that the inner shaft of the pressure block can be stably buckled and pressed. Through the setting of the inner shaft-inner shaft of the stop block, the inner shaft-inner shaft of the stop block can limit the position of the inner shaft of the spring inner shaft, so that the inner shaft of the spring inner shaft can be stably compressed and rebounded in front of the inner shaft of the limit block. Through the setting of the inner shaft of the bearing seat and the inner shaft of the bearing, the inner shaft of the cam disc rotates on the inner shaft of the bearing seat through the inner shaft of the bearing. The inner shaft of the bearing ensures the smoothness of the rotation of the inner shaft of the cam disc on the inner shaft of the bearing seat, so that the inner shaft-inner shaft of the buckling mechanism can be buckled smoothly.
