Description
Technical field
The present invention relates to the guide rail field of measuring technique, particularly relate to a kind of high precision length apart from machine tool guideway location survey frock and method.
Background technology
Line slideway generally is made up of guide rail, slide block, reverser, rolling body and retainer etc., it is a kind of rolling bearing of the novel relative linear reciprocating motion of work, can roll with the steel ball between slide block and guide rail and replace direct sliding contact, and rolling body can be realized infinite loop by reverser in raceway and slide block, has advantages such as simple in structure, that static and dynamic friction coefficient is little, bearing accuracy is high, precision stability is good.Through the development of decades, line slideway has become international a kind of supporting and gearing day by day, and more and more by numerically-controlled machine, numerical control machining center, precise electronic machinery, automation equipment adopt, and are widely used in commercial production.
Because it is very high to forge accuracy requirement, length can't integral production be processed apart from line slideway, can only be spliced than short lead rail by plurality of sections, and the whole linearity after its splicing is installed directly influences machining accuracy of NC machine tool.Guide rail linearity error detection method at present commonly used has: grind a method, leveling ruler draws table relative method, padding method, draws steel wire detection method, level meter detection method, optical flatness gauge (autocollimator) detection method etc.These detection methods are owing to be subjected to artificial affecting often can't finish long location survey apart from line slideway greatly, and accuracy of detection also can't be guaranteed.
Laser tracker is a kind of three-dimensional measurement instrument of high-precision large-range, utilize ADM (absolute stadimeter) and IFM (laser interferometer) technology, has adopted simply, the design of stable performance, technology maturation, realizes high-acruracy survey under working environment.Be equipped with the laser-bounce target, its measurement range can contain the spherical measurement space that diameter reaches 160 meters.The Survey Software of tracker can be carried out bidirectional data transfers with any CAD software on the market, shows the deviation of actual value and theoretical value in real time, thereby finishes the evaluation of surf zone.
Introduce laser tracker and carry out data acquisition apart from line slideway long, and the data that collect are analyzed, simulate, contrasted by the data processing model and the fitting algorithm of its science, thereby determine long apart from line slideway in surface level with vertical plane in the straightness error value, and guide rail is adjusted in real time according to error, operating so repeatedly, can effectively position apart from machine tool guideway, realize that the interior alignment error of long distance is controlled high precision length.
And the target ball of laser tracker measurement surface of contact is circular, can not directly on line slideway, obtain the accurate measurement point in position, more can't the actual response line slideway in the linearity variation tendency of surface level and vertical plane, therefore must make the corresponding correctness of measuring frock with auxiliary detection.
Summary of the invention
Technical matters to be solved by this invention provides a kind of high precision length apart from machine tool guideway location survey frock and method, makes that the laser target ball can be according on line slideway.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of high precision length apart from machine tool guideway location survey frock, comprise the frock base that is installed on the guide rail, described frock base is vertical mutually with the bottom surface with the side that guide rail is in contact with one another; Be fixed with the laser target ball pedestal that is used to adsorb the laser target ball on the described frock base.
The side that described frock base and guide rail are in contact with one another and the smooth finish of bottom surface are 3.2.
Described frock base is made by the Q235-A steel.
Described laser target ball pedestal passes through three flat key screw retention on described frock base.
The technical solution adopted for the present invention to solve the technical problems is: also provide a kind of high precision length apart from the machine tool guideway locating measurement method, may further comprise the steps:
(1) above-mentioned high precision length is installed on the line slideway apart from machine tool guideway location survey frock;
(2) the laser target ball is installed on the laser target ball pedestal;
(3), will measure frock after data acquisition is finished and slide to next test point along line slideway to the test point image data;
(4) generating laser in the laser tracker carries out from motion tracking the laser target ball under the driving of automatic motor, and repeating step (3), until the collecting work of finishing all test points on the line slideway.
Described test point is the head and the tail position of every section short lines guide rail.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the present invention compared with prior art, have following advantage and good effect: the present invention realizes fitting tightly by frock base and line slideway, can slide automatically along line slideway by drive unit, and carry out having when line slideway is measured fast at the auxiliary laser tracker, effectively, accurate characteristics, can increase work efficiency greatly, realize unmanned operation substantially, reduce the cumulative errors that human factor produced.
