Rear-mounted pneumatic double acting chuck mechanism

Abstract

The invention discloses a rear-mounted pneumatic double acting chuck mechanism. The rear-mounted pneumatic double acting chuck mechanism comprises a base, wherein a gas path sliding ring mechanism ismounted on one side of the base; a housing is mounted on the other side of the base; a cylinder unit is mounted at one end away from the base, of the housing, and consists of a first cylinder, a second cylinder, a third cylinder and a fourth cylinder; the first cylinder, the second cylinder, the third cylinder and the fourth cylinder are linked through a gear pair mechanism; and clamping claws aremounted at one ends away from the housing, of the first cylinder, the second cylinder, the third cylinder and the fourth cylinder. According to the rear-mounted pneumatic double acting chuck mechanism disclosed by the invention, a pairwise clamping claw linkage structure is formed; a linear guide rail mechanism is mounted on each cylinder body; each clamping claw is directly driven by the corresponding cylinder body to move; and every two cylinders are controlled by one gear rack to perform simultaneous movement, and a gear rack pair is formed, so that transmission moment is large and stable,and the grasping performance of the clamping claw is guaranteed to be stable and reliable.

Description

technical field [0001] The invention relates to the technical field of pneumatic chucks, in particular to a rear-mounted pneumatic double-action chuck mechanism. Background technique [0002] The laser pipe cutting machine can process round pipes, square pipes, I-beams, channel steels and other workpieces with symmetrical cross-sections. It is very important for the clamping of the workpieces. The laser pipe cutting machine must be compatible with all symmetrical workpieces and meet the clamping requirements. The function, the stability of the workpiece clamping force and the clamping accuracy are all very important. The traditional ones use extended clamping clamps, which have problems such as unstable clamping force, prone to offset, low clamping precision, and inability to last for a long time. At present, the processing precision of the laser pipe cutting machine industry is not enough, the root cause lies in the fixture Due to insufficient precision, there are problems...

Problems solved by technology

The traditional ones use extended clamping clamps, which have problems such as unstable clamping force, prone to offset, low clamping precision, and inability to last for a long time. At present, the processing precision of the laser pipe cutting machine industry is not enough, the root cause lies in the fixture Due to insufficient precision, there are problems in the design of the mechanical structure, which makes the laser pipe cutting machine unable to achieve the expected processing accuracy
