Problems solved by technology
In order to ensure that the axis of the circular pipe coincides with the rotation axis of the chuck in the existing chuck, all the jaws on the chuck often move synchronously during design, so that all the jaws and the center of the chuck keep the same However, for pipes with non-circular or non-regular polygonal cross-sections, there are cases where some claws cannot be fixed on the side wall of the pipe, resulting in the inability of the claws to fix the pipe firmly. It is necessary to set a specific backing plate on the claws. Allows all jaws to be fixed to the side wall of the pipe
To install different types of pipes, it is necessary to install backing plates of different specifications on the claws, which increases production costs

The invention provides a pneumatic chuck for a laser cutting machine. The pneumatic chuck comprises a support table, a rotary cylinder, an air cylinder, a rack, an arc-shaped rack, a bending rod, a fixed block, a clamping plate and clamping jaws, wherein the rotary cylinder is rotatably connected to the support table, the air cylinder is fixed to one side of the rotary cylinder, a piston rod of the air cylinder extends into the rotary cylinder, the rack is arranged on the piston rod, the rack is engaged with the arc-shaped rack, the arc-shaped rack is fixed to one end of the bending rod, the other end of the bending rod is connected with the clamping jaws by virtue of hinged blocks, the clamping jaws are connected to the clamping plate in a sliding mode, the clamping plate is fixed to thefixed block, and the fixed block is arranged in the rotary cylinder in the sliding mode. According to the pneumatic chuck for the laser cutting machine, the position of the fixed block is adjusted, sothat different effects are generated on the clamping jaws by the bending rod, and the clamping jaws synchronously move at different distances so as to clamp special pipes.
Description
technical field [0001] The invention relates to the field of pneumatic chucks, in particular to a pneumatic chuck used for a laser cutting machine. Background technique [0002] Chucks are widely used in laser pipe cutting, and play an important role in fixing the pipe to be cut and driving the movement of the pipe to be cut. [0003] Existing chucks for laser cutting are generally rotatable, and the rotation of the chuck drives the rotation of the pipe, so that different positions of the pipe are aligned with the laser cutting head, so that the laser cutting head can cut the pipe. In order to ensure that the axis of the circular pipe coincides with the rotation axis of the chuck in the existing chuck, all the jaws on the chuck often move synchronously during design, so that all the jaws and the center of the chuck keep the same However, for pipes with non-circular or non-regular polygonal cross-sections, there are cases where some claws cannot be fixed on the side wall of ...
