Description
Technical field
The utility model relates to long stroke mother lead screw line detector, relates in particular to the pick-up unit 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 and walk, and the installation accuracy of leading screw directly determines the precision of processing.Long stroke leading screw is because the factor of its deadweight, and deflection deformation can appear in the middle part, and the deflection deformation that produces because of deadweight is when work, because the reverse support effect of feed screw nut can not constitute any harmful effect to complete machine operation and machining precision.But for high precision machine tool, the axis of leading screw and both sides Y are very high to the depth of parallelism requirement of guide rail, and this also is an important indicator guaranteeing machine mass.
In the whole machine installation process, when detecting the leading screw and the two side rails depth of parallelisms, the deflection deformation of leading screw can produce serious influence to testing result, makes the result who detects can not correctly reflect depth of parallelism index.Reason is that two side rails rigidity are high, and leading screw makes the middle part deflection deformation can occur owing to be the two end supports structure.Cubing generally is to be detachably connected on the guide rail, and limit walking, frontier inspection are surveyed, and the Z of the Z at the two ends of leading screw side bus in the middle of height will be higher than be to height, is difficult to obtain accurately the result who detects.
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-purpose dial holder of leading screw; " to the bed ways depth of parallelism Two patent documentations disclose comparatively close technological means.Adopt the mode that simultaneously leading screw top bus, side bus is 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, short leading screw is detected can satisfy request for utilization.But during the long-range leading screw detected, because the long-range leading screw when having certain deflection deformation amount, is difficult to obtain side bus parameter accurately.
The utility model content
The utility model provides a kind of under the prerequisite of rule that complies with the nature to above problem, can accurately obtain the detection data, and then improves the pick-up unit of the long stroke leading screw installation accuracy of product installation accuracy.
The technical scheme of the utility model is: said leading screw is movably connected on the frame; Said frame is provided with a pair of Y parallel with said leading screw to guide rail; Be connected with feed screw nut on the said leading screw, said pick-up unit comprises portal frame, X axis rail, X axle slide block, table one and table two;
Two foot sections of said portal frame are not movably connected to guide rail through Y axle slide block and said Y;
Said X axis rail is fixedly connected on the side of said portal frame support body, said X axis rail level;
Said X axle slide block is movably connected on the said X axis rail;
Said table one is removably connected on the side of said portal frame support body, is used to detect the position of said X axle slide block on X-direction;
Said table two is removably connected on the said X axle slide block, is used to detect the said leading screw side bus and the depth of parallelism of said Y between guide rail.
Also comprise X axle slide-driving device, said X axle slide-driving device comprises synchronous band, synchronous pulley and synchronous support; The end face that said synchronous pulley has is a pair of, be arranged on said portal frame support body; Said synchronous band is arranged between the said a pair of synchronous pulley; One end of said synchronous support is fixedly connected said synchronous band, the other end is fixedly connected said X axle slide block.
Also comprise the leading screw supporting mechanism, said leading screw supporting mechanism is screw jack or hydraulic jack; Be used to overcome the amount of deflection of said leading screw.
In the applied environment of the utility model, a pair of Y ensures (after being mounted to frame respectively, in a clamping, accomplishing the processing of two side rails) to the mutual precision of guide rail by preceding road manufacturing procedure, and this provides the guarantee of benchmark property to follow-up detection.The bipod of portal frame removably connects to guide rail through Y axle slide block and both sides Y respectively, and under the prerequisite of guaranteeing Y axle slide block and guide rail quality of fit, portal frame is in service to have guarantee with respect to Y to the verticality of guide rail.
Possessing under the situation on above-mentioned basis, the table two on the portal frame can become detection " benchmark "; But; Because when feed screw nut is in the two ends of leading screw in the long stroke leading screw; Be difficult to obtain the installation accuracy of leading screw, so this case when operation, feed screw nut moved to the medium position of leading screw; Thereby can obtain the positional precision at both ends exactly, the 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 the table one that is used to appraise and decide table two reference position again, 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, and when especially stroke was longer, deflection was bigger; Although this deflection can not exert an influence to machining precision, running precision; But accuracy of detection is had bigger influence, because the side bus of distortion axially is sagging curve at Z, table two is difficult in continuous walking, obtain the side bus data.Therefore before realizing aforementioned means, this case need be set up the step that amount of deflection overcomes, to obtain the depth of parallelism parameter of real side bus and guide rail to greatest extent.
