Machine tool work chuck - has three radially adjustable jaws with internal axial clamp joined to baseplate

摘要

The work chuck is fixed to a baseplate and clamps work. It centres it inside and out via three radially adjusting jaws. An inside axial clamp (16) releasably joined to the baseplate (8) and led through the centre hole in the chuck (2) fixes the work (10) at right angles to the baseplate and the chuck is fitted with peripheral segments (49) whose top surface is aligned with that of the chuck body (6). Outer axial clamps releasably connected to the segments fix a second workpiece at right angles to the baseplate. Axial positioner pins (30) axially position and support the workpiece on their segments and/or on the chuck body, and holders in the form of threads, bores and/or on the chuck body, and holders in the form of threads, bores and/or grooves (34) in the segments (49) and chuck releasably fix the positioners on segments and chuck and at the same time releasably fix the outer axial clamps to the segments. USE/ADVANTAGE - Machine tools. Chuck secures axially and radially pressure sensitive workpieces repeatedly as required and holds them centred for machining.
