Abstract
The invention discloses a double-ball corner gauge which can measure the actual corner position of two rotating shaft rotary tables of a five-axis numerical control machine. The double-ball corner gauge is instrument in which two steel balls are fixed on a magnetic force base, and the actual rotation angles of the tables through measuring the positions of the two steel balls.
Description
Affiliated technical field
This technological invention relates to a kind of method that five-axle number control machine tool two rotating shaft worktable rotational angles are detected and the instrument of use thereof.
Background technology
The comprehensive corner accuracy of two rotating shaft worktable of five-axle number control machine tool detect international, domestic all be a blank.At present, known detection method is in the laboratory independent angular errors test to be carried out in each rotating shaft of two rotating shaft worktable, and must use expensive optical instrument (as autocollimator) that high precision polyhedron (as 36 prisms) is carried out uniformly-spaced (10 °) outer corner measurement.This method is not suitable for the production scene five-axle number control machine tool running status is carried out timing monitoring, and the data after detecting do not have actual value to machine tool motion precision analysis and error compensation yet, because the independent rotation error of each rotating shaft of rotary work-table can not reflect the legitimate reading after the worktable diaxon moves simultaneously fully.Thus, the development of five-axle number control machine tool, application are badly in need of occurring and can be carried out simple and easy to do method and the testing instruments that comprehensive rotation error detects to two rotating shaft worktable.
Summary of the invention
In order to solve five-axle number control machine tool two rotating shaft worktable actual rotational angle accuracy detection problems, this technological invention provides a kind of detection method and detecting instrument of easy, easy row, i.e. two point form detection method and two ball corner gauges.
The technical scheme that this invention solves its technical matters is: the steel ball of two same sizes is fixed on the magnetic force base, constitutes a two ball gauge.Before the detection, two ball gauges are adsorbed on the worktable by magnetic force, and two centre of sphere on lines of two ball gauges are overlapped with a certain selected coordinate axis on the lathe.During work, two ball gauges when needing to detect, by two ball centre present positions of two ball gauges are measured in good time, are determined the true corner of worktable with working table movement.
Concrete grammar is as follows:
1. when installing, make two ball lines of centres of two ball gauges vertical with two planes that turning axle constituted of worktable;
2. pedestal ground, end face and the side of two ball gauges guaranteed parallel with the line of centres of two balls when making.After two ball gauges are adsorbed on the worktable, measure its end face and side, to realize the requirement of the first step;
3. when worktable turns to the optional position, by being installed in any three points of every spherome surface on the two ball gauges of three-dimensional probe measurement on the machine tool chief axis, the center of calculating this spheroid thus;
4. calculate the position angle of two ball centre lines, obtain worktable diaxon actual rotational angle separately.
Two point form detects principle
Two sphere center positions have been demarcated two definite points of platen coordinate system on two ball gauges, and two centre of sphere lines are definite vectors of work space, and the variation of this vector position is the result that two axles of worktable act on simultaneously.Therefore, the real rotational angle of worktable diaxon can be calculated by the variation of measuring two ball centre line vector positions.Relatively result of calculation and the nominal rotational value of worktable, can the analytical work platform each actual rotation precision and angular errors.
Adopt steel ball to be because the center of spheroid can be determined by position any on the spherome surface and known radius of sphericity at 3.No matter where two ball gauges rotate in company with worktable, as long as detect the coordinate position of three points separately on two spherome surfaces, the center of this ball can determine that just simultaneously, the actual rotary position of worktable is also determined errorless.
The position finding of 2 spherome surface points adopts present popular three-dimensional probe to finish easily on two ball gauges, the calculating of ball centre position can be carried out according to predefined program by numerically-controlled machine, result after detecting, calculating can be stored in the numerically-controlled machine controller, uses for follow-up error compensation.
The beneficial effect of this invention is: can measure five-axle number control machine tool two rotating shaft worktable actual rotational angle positions, and the comprehensive rotation error of evaluation work platform, and carry out the angular errors compensation in good time.This invention adopts two steel balls and a magnetic force base, and is simple in structure, easy to use, is easy to make.
