Description
Technical field
The utility model relates to a kind of machining equipment, relates in particular to a kind of rig with mechanical positioner.
Background technology
When with traditional rig, carrying out Drilling operation, in order to determine whether the center cutter position is the center of workpiece to be machined, usually need to mark in the position that surface of the work need to be processed the center line in hole, and stamp the dotting punch of center sample, then mark the circumference in hole by the size in hole.During boring, the center that first makes drill bit aim at dotting punch gets out shallow hole, observes shallow hole whether with one heart with scribed circle, accurately after, continued boring.If shallow hole departs from the center of scribed circle, need travelling workpiece that both are aimed at,, if deviation distance is large, also need dotting punch again.This kind drilling and positioning method at centre punch at the moment, more or less there is operate miss, add the reason of workpiece itself, the accuracy of dotting punch further reduces, easily cause dotting punch not just, the circle etc. phenomenon, the drill bit location is inaccurate, chisel edge sideslip in dotting punch thereby cause, and makes the center skew in hole.Operating personnel are by the distance between naked eyes intuition observation shallow hole center and scribed circle center, although can obtain certain finishing foundation like this, but can not obtain concrete correction deviant, help to accurate correct for borehole position is little, again dotting punch time error correction value is difficult to control, can not reach accurately and proofread and correct, have very large overproof probability., if during boring, the pitch-row requirement is arranged, need test drilling limit, limit just borrowing, if while processing porous on a workpiece, hole of every brill, workpiece must mobile centering once, and bit central is overlapped exactly with the drill center of workpiece, this mode is to be difficult to realize.
Published " location drilling method " the 61st page and the 76th page of " scientific and technological information " magazine of the 36th phase in 2007, provide a cover to be used for the assembly of location drilling in this article and realized the method for locating with this assembly.Assembly comprises high accuracy shelves iron, pressing plate, dog screw axle, slip gauge and calculating apparatus, at first calculate the size of slip gauge according to the actual size of pin diameter, the fixing workbench of drilling machine, the dog screw axle is arranged on the dop of drilling machine, the swivel feeding handle makes the dog screw axle drop near the Drilling machines bench face and leave a small amount of gap, locking feeding handle.Vertically select slip gauge to be placed on work top and near bearing pin according to calculating, shelves iron is leaned against on slip gauge and makes contact gap level off to zero, rotating nut locking shelves iron, promote slip gauge and move to slip gauge and bearing pin gapless and micro-frictional force is arranged along shelves are untouchable, make between the limit of grade iron and dog screw axle size is accurately arranged.After with slip gauge, shelves iron being positioned, take off bearing pin and slip gauge, with Cutting tool installation manner on dop, workpiece is placed on the work top of drilling machine close with shelves iron, with pressing plate with Work-sheet pressing.The center line of bearing pin is the center line at bore position place on workpiece.
Although disclosed this kind drilling and positioning method has solved the some shortcomings of traditional dotting punch localization method, but also there are a lot of deficiencies in this kind method, different bore positions according to the different size workpiece, need to use the different slip gauge of size to position, and need to calculate the size of selecting slip gauge according to the bearing pin size, in order to guarantee machining accuracy, perpendicularity, the flatness of slip gauge and shelves iron are had relatively high expectations.If workpiece size is large, slip gauge also needs very large size, causes slip gauge weight large, and the personnel of being awkward take.
