Abstract
The invention discloses a clamping tool provided with an air cylinder and restoring torsion springs. The clamping tool comprises an installation base. An installation cavity is formed in the installation base. At least three clamping arms are arranged in the installation cavity. The clamping arms are evenly distributed in the circumferential direction. The heads of the clamping arms stretch forwards out of the installation cavity. The middle of each clamping arm is hinged to the installation base. One clamping arm ejector rod is arranged in the portion, behind the clamping arms, of the installation base in a penetrating mode. The front end of the clamping arm ejector rod aligns to the tails of the clamping arms. When the clamping arm ejector rod moves forwards, the tails of the clamping arms are pushed to be separated from one another, and the heads of the clamping arms are pushed to be close to one another. The clamping arm ejector rod is driven by the air cylinder. The clamping arm restoring torsion springs are arranged between the clamping arms and the installation base. The two ends of each clamping arm restoring torsion spring abut against the corresponding clamping arm and the installation base respectively. The clamping arm restoring torsion springs push the tails of the clamping arms to be close to one another, so that the clamping arms are restored. By the adoption of the structure, clamping of bevel gear shafts with different diameters is achieved, operation is easy, and the application range is wide.
