Description

A kind of using method of pick-up unit of long stroke leading screw installation accuracy
Technical field
The present invention relates to long stroke mother lead screw line detector and using method thereof, relate in particular to pick-up unit and the using method thereof of NC turret punch machine, numerical control laser cutter worktable driving leading screw.
Background technology
The feeding table of digital control plate processing equipment, worktable adopt long stroke leading screw to drive upper beam walking, and the installation accuracy of leading screw directly determines the precision of processing.Long stroke leading screw is due to the factor of its deadweight, and middle part there will be deflection deformation, and the deflection deformation producing because conducting oneself with dignity, in the time of work, due to the reverse support effect of feed screw nut, can not form any harmful effect to complete machine operation and machining precision.But for high precision machine tool, the depth of parallelism of the axis of leading screw and both sides Y-direction guide rail requires very high, and this is also an important indicator guaranteeing machine mass.
In whole machine installation process, while detecting leading screw and both sides guide rail parallelism, the deflection deformation of leading screw can produce serious influence to testing result, makes the result detecting can not correctly reflect depth of parallelism index.Reason is that two side rails rigidity are high, and leading screw is owing to being two end supports structure, makes middle part there will be deflection deformation.Cubing is to be generally detachably connected on guide rail, and limit walking, frontier inspection are surveyed, and the Z-direction height at the two ends of leading screw side bus will be higher than middle Z-direction height, is difficult to obtain accurately the result of detection.
In association area, State Bureau in " CN201007640Y, the quick leading screw generatrix check tool of 2008.1.16. bulletin; the disclosed CN102322787A of 2012.1.16., measure new method and the special dial holder of leading screw to the bed ways depth of parallelism; " two patent documentations, disclose comparatively close technological means.Adopt the mode simultaneously leading screw top bus, side bus being detected to obtain position degree (depth of parallelism) data of bus with respect to guide rail.
The common feature of this two case is to have ignored leading screw because of the sagging distortion that amount of deflection produces, and adopts the technological means of above-mentioned two documents, and short leading screw is detected and can meet request for utilization.But during long stroke leading screw is detected, while there is certain deflection deformation amount due to long stroke leading screw, be difficult to obtain side bus parameter accurately.
Summary of the invention
The present invention is directed to above problem, provide a kind of under the prerequisite of rule that complies with the nature, can detect data by Obtaining Accurate, and then improve pick-up unit and the using method thereof of the long stroke leading screw installation accuracy of product installation accuracy.
Technical scheme of the present invention is: described leading screw is movably connected in frame, described frame is provided with a pair of Y-direction guide rail parallel with described leading screw, on described leading screw, be connected with feed screw nut, described pick-up unit comprises portal frame, X-axis guide rail, X-axis slide block, table one and table two;
Two foot sections of described portal frame are not movably connected by Y-axis slide block and described Y-direction guide rail;
Described X-axis guide rail is fixedly connected on the side of described portal frame support body, described X-axis guide rail level;
Described X-axis slide block is movably connected on described X-axis guide rail;
Described table one is removably connected on the side of described portal frame support body, the position for detection of described X-axis slide block in X-direction;
Described table two is removably connected on described X-axis slide block, for detection of the depth of parallelism between described leading screw side bus and described Y-direction guide rail.
Also comprise X-axis slide-driving device, described X-axis slide-driving device comprises Timing Belt, synchronous pulley and synchronous bracket; The end face that described synchronous pulley has is a pair of, be arranged on described portal frame support body; Described Timing Belt is arranged between described a pair of synchronous pulley; One end of described synchronous bracket is fixedly connected with described Timing Belt, the other end is fixedly connected with described X-axis slide block.
Also comprise leading screw supporting mechanism, described leading screw supporting mechanism is screw jack or hydraulic jack; For overcoming the amount of deflection of described leading screw.
Using method of the present invention, carry out according to the following steps:
1), described pick-up unit is mounted on described a pair of Y-direction guide rail;
2), described feed screw nut is moved to the centre position of described leading screw;
3), amount of deflection overcomes; Described jacking mechanism is arranged on to the below of optional position, described leading screw middle part, any side of described feed screw nut; Then utilize described table one or table two to detect the Up Highway UHW of described leading screw, by the regulating action of described leading screw supporting mechanism, until the Up Highway UHW level of described leading screw;
4), one end is detected; Described portal frame is arranged on to one end of leading screw, reconciliation statement two contacts the side bus of described leading screw, and reconciliation statement one contacts the side of described X-axis slide block simultaneously; Operate immediately described portal frame to the operation of feed screw nut direction, until arrive the end of this one end towards described feed screw nut;
5), the other end detects; Utilize described X-axis slide-driving device to drive described X-axis slide block to move toward the outer side, to dodge described feed screw nut; Then operate the other end motion of described portal frame to described leading screw, cross after described feed screw nut, utilize described X-axis slide-driving device to drive described X-axis slide block to reset, continue the distal movement towards the described other end;
6), complete.
In applied environment of the present invention, the mutual precision of a pair of Y-direction guide rail, You Qian road manufacturing procedure ensures (be mounted to respectively after frame, completing the processing of two side rails in clamped one time), this provides the guarantee of benchmark to follow-up detection.The bipod of portal frame removably connects by Y-axis slide block and both sides Y-direction guide rail respectively, is guaranteeing under the prerequisite of Y-axis slide block and guide rail quality of fit, and the portal frame verticality with respect to Y-direction guide rail in service has guarantee.
In the situation that possessing above-mentioned basis, the table two on portal frame can become detection " benchmark "; But, during due to the two ends of feed screw nut in long stroke leading screw in leading screw, be difficult to obtain the installation accuracy of leading screw, therefore when this case operates, feed screw nut is moved to the medium position of leading screw, thereby can obtain exactly the positional precision at both ends, location parameter when this installs regulating is of great importance; Like this, just need segmentation to detect.For unlikely forfeiture precision in segmentation detects, this case has increased again the table one for appraising and deciding table two reference position, so just can guarantee that the X axis coordinate position of table two in two ends are detected is consistent, and then can guarantee accuracy of detection.
In addition, the deflection deformation of leading screw is inevitable, especially when stroke is longer, deflection is larger, although this deflection can not exert an influence to machining precision, running precision, but accuracy of detection is had to larger impact, because the side bus of distortion is sagging curve in Z-axis direction, table two is difficult to obtain side bus data in continuous walking.Therefore realizing before aforementioned means, this case need be set up the step that amount of deflection overcomes, to obtain to greatest extent the depth of parallelism parameter of real side bus and guide rail.
