Description
Technical field
The utility model relates to a kind of machine tools, relates in particular to a kind of clamping apparatus that is used for quick centering workpiece hole center line, particularly is used for processing the higher and not high part of the precision of milling machine that uses of some accuracies of form and position own.
Background technology
In field of machining, often to use the two ends in manufactured hole, beat the table centering and make it the directed benchmark of parallel or vertical work with the milling machine guide rail and could begin down preface processing.In order to measure the simple mandrel that cooperates that utilizes usually, the dial gauge (amesdial) on the mobile milling machine slide unit comes centering mandrel two ends, thus the central axis of alignment holes.
The main pilot hole of guiding of one of conventional method processing column shape part on common vertical knee-type milling machine (the main pilot hole of the guiding of cylindrical component usually has strict position accuracy of form and position requirement each other with part cylindrical, main pilot hole etc.) is to clamp cylindrical with vice, play table and proofread and correct cylindrical, rotary main shaft is played table again for 180 ° and is proofreaied and correct cylindrical, twice reading differs in the 0.01mm scope, this is during milling machine spindle is looked for respect to the cylindrical axis, to guarantee the main pilot hole both sides symmetry of axis to foreign round; Then at the supporting precision pole that grows tall of packing into of main pilot hole, get up and down at 2 and be more or less the same by beating dial gauge alignment pole in 0.01mm, can guarantee main pilot hole axis normal like this in milling machine table, thereby finish the part processing location.After clamping part, the beginning processing work, pull down workpiece repetition aforesaid operations after finishing and process next part, and in actual process, owing to be on arc surface, to mill main pilot hole, and vice sign indicating number folder is monolateral moving and can not symmetry moving, the gap error that unclamps grip vice can make workpiece with respect to vertical little the moving in milling machine spindle position, the structure of common vertical knee-type milling machine workbench, determined workbench in the process that moves, can interfere mutually, influence is because when moving up and down workbench, workbench also has trickle moving at left and right directions, thereby destroyed the milling machine positioning accuracy, like this, in the higher main pilot hole of machining accuracy, precision just can not get guaranteeing, and the efficient of Tiao Zhenging is also very low like this, and labor strength is bigger.
Two of conventional method is that cylindrical component is placed in the V-shaped groove, utilize the fixed middle function of V-shaped groove to make milling machine spindle look for the middle symmetry that guarantees with respect to cylindrical, the same then method is at the main pilot hole precision pole that grows tall of packing into, beat dial gauge alignment pole and get up and down at 2 and be more or less the same by moving up and down the milling machine slide plate in 0.01mm, this is to guarantee perpendicularity, after clamping part, the beginning processing work, pull down workpiece repetition aforesaid operations after finishing and process next part, though improved the efficient of workpiece adjustment in this way and reduced labor strength, yet still depend on the mobile accuracy of common vertical knee-type milling machine workbench, do not solve common vertical knee-type milling machine workbench about, about, the precision that influences each other when moving forward and backward workbench misalignment problem.
