Embodiment
As shown in Figure 1, 2, a kind of overlength guide rail that has the straightness accuracy regulating device comprises guide rail 1 and straightness regulating device 2,50～80 meters of guide rail 1 length, and the two ends with guide rail 1 on guide rail 1 are provided with the precision measure device.Air supporting controlling mechanism 11 is arranged on the straightness regulating device 2.Two straightness regulating devices 2 are installed in the basal surface position at the nearly two end part of guide rail 1.
As shown in Figure 3, this air supporting controlling mechanism 11 comprises air supporting regulating block 4, suction port 7 and the hole 8. of damming has 4 holes 8 of damming that diameter is minimum in the 4 upper surface settings of air supporting regulating block, be distributed on the diagonal of air supporting regulating block 4, on the side of air supporting regulating block, be shaped on an inlet hole 7, pressurized gas enter air supporting regulating block 4 through inlet hole 7, air can spray at a high speed through the hole 8 of damming, will regulate object and be placed on the air supporting regulating block 4, then the object of regulating almost frictionless move arbitrarily thereon.
This straightness regulating device 2 has used air supporting controlling mechanism 11, its great advantage is, this air supporting controlling mechanism 11 is by from holding back hole 8 air of ejection at a high speed, make air supporting regulating block 4 realize zero friction, reduced to greatest extent because the mutual friction of equipment part phase, and the error that causes, in the time of can realizing that granite guide rail, machine tool guideway and some high-precision equipments and product carry out the adjusting of position, up-down adjustment and left and right adjusting each naturally independently and be independent of each other.
One side of air supporting controlling mechanism 11 is fixed with left and right displacement spring controlling mechanism 3 along its axial direction in a wherein end of air supporting controlling mechanism 11, and is fixing with air supporting regulating block 4 by cushion block 12 and baffle plate 13.Rely on the continuity and the supportive of spring tension, the precision that can regulate guide rail left and right directions straightness accuracy as required.Old way realizes the left and right displacement adjustment with weight bump jack, regulates the back precision owing to stress relation, and can change influences degree of regulation.This device solves this difficult problem, improved the adjustment precision greatly.
Straightness regulating device 2 is provided with hemisphere controlling mechanism 5, this hemisphere controlling mechanism 5 is by the upper surface of screw at the moving wedge 9 of wedge controlling mechanism 6, be connected by sphere slip rotation restriction with the lower end of air supporting controlling mechanism 4, the hemisphere connection has the advantage that any direction is freely located, can be according to being conditioned the required angle of object, the upper surface of free adjustment air supporting controlling mechanism 4 makes it with to be conditioned the object surface of contact parallel.
Also be provided with wedge controlling mechanism 6 on base, fixedly connected with described hemisphere controlling mechanism 5, this wedge controlling mechanism 6 comprises moving wedge 9 and quiet wedge 10, and the two moves by the precision lead screw rotation and connects.When needs are finely tuned, only need shake leading screw gently, the highi degree of accuracy surface of contact of its moving wedge 9 promptly can slide along deciding wedge 10 high-precision surface of contact, realize fine setting, wedge controlling mechanism 6 is widely used in machine industry, has simple in structure, be convenient to operation, characteristics such as compact structure and good stability.This product has carried out the high-precision processing of surface of contact and has handled on the basis that keeps its original structure to its surface of contact, improved degree of regulation, as required the precision of free adjustment guide rail above-below direction straightness accuracy.
This set-up procedure that has the overlength guide rail of straightness accuracy regulating device is:
The first step: determine basic rack (is benchmark with middle guide rail), guide rail puts the side of guide rail 1 and upper surface adjusting in place, with this front benchmark and side group standard as whole adjusting as required according to its fixed-site of 2/9 supporting handle.
Second step: after having determined basic rack, to basic rack two directions butt joint guide rail 1, left and right directions all can according to own needs.According to the position of basic rack, according to 2/9 Support Position straightness regulating device is in place in advance, then guide rail 1 is lifted on the straightness regulating device 2, air supporting regulating block 4 surfaces of straightness regulating device 2 and the bottom surface of guide rail 1 must wiped clean.After finishing, the guide rail lifting contacts with guide rail 1 with the left and right displacement spring controlling mechanism 3 on the straightness regulating device 2, and fixed guide 1 left and right directions, rear rail 1 move left and right prevents to ventilate.
The 3rd step: give straightness regulating device 2 ventilations; guide rail 1 can (be noted: carry out frictionless motion owing to guide rail after the ventilation by frictionless motion on straightness regulating device 2 in this case; the guide rail left and right directions is fixing, and fore-and-aft direction need artificially be protected).
The 4th step: allow guide rail 1 near basic rack, play (generally reserving intermediate space 20 roads is that guide rail has docked back filler fixed guide use) with copper foil pads in the middle of the two guide rail interfaces, reference level and side group are accurate in the face of connecting the difference of height that the wedge regulating mechanism on the straightness regulating device 26 is regulated above the guide rail 1 on the guide rail 1, left and right displacement regulating mechanism 3 is adjusted the difference of height of guide rails 1 side reference level and is shown roughly levelling with dragging, and the difference of height of measuring guide rail 1 by break-make gas repeatedly is the air supporting gap of straightness regulating device 2 and guide rail 1.Adjusting to the laser light target installs air supporting regulating block 8 and (adopts main measurement face and side guide surface all to adopt the slick and frivolous piece of aspiration, adopted with the guide rail master and measured the tilt fixing that face and side guide surface angle match.) can safe operation on two guide rails 1.Adjust laser the last reference level of two guide rails 1 and the straightness accuracy of side reference level are measured, guide rail 1 is adjusted according to measurement result.Going up reference level during adjustment will have pre-allowance (adjust guide rail and will exceed the height that basic rack and straightness regulating device equate with the air supporting gap of guide rail 1), dies after adjustment finishes.The straightness accuracy adjustment of guide rail 1 finishes.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example, and every variation of making in the utility model essential scope, remodeling, interpolation or replacement and application all should belong to protection domain of the present utility model.
