Chuck assisted clamping device

Abstract

The utility model discloses a chuck auxiliary clamping device belongs to laser pipe cutting machine chuck technical field. The device is based on original chuck main part, sets up auxiliary clamping mechanism at its front side, auxiliary clamping mechanism includes the big gear of being arranged in the front part of chuck main part and having the clamping hole in the middle, the pinion that is engaged with big gear and is driven by drive motor, and the clamping subassembly of being arranged in the front side of big gear, the clamping subassembly contains two groups of central symmetry's multi -section double -cylinder air cylinder, two groups of clamping plate with antiskid boss, two groups of guide shaft, still include the linkage unit that is formed by pulley and steel wire rope, clamping plate is along the guide axle sliding through the guide sliding sleeve. The clamping plate and original chuck front side gyro wheel form long force arm clamping to avoid angular deviation in the device, two stage air cylinder adapts wide -bore and prevents thin -walled pipe deformation, and the linkage of steel wire rope and pulley simplifies the structure and guarantees synchronous centering, especially suitable for two chuck laser pipe cutting machine front chuck, can promote the processing precision of tail material.
