Abstract

The utility model belongs to the mechanical manufacturing field and can realize the drawing and surveying to various moulds, models, box workpieces, casing workpieces and large calcining and casting workpieces. The double-arm separating drawing surveying apparatus for three-coordinate is composed of a working table, a guide rail, a column, a column sliding plate, arms and arm sliding plates. In the structure, the double-arm separating manner is used, each arm can work independently and can also work together, the data collected is processed by a computer, printed and drawn to a photograph.

Description

Double-arm seperating drawing surveying apparatus for three-coordinate

The utility model belongs to mechanical manufacturing field, be widely used in the production of big machineries such as automobile, tractor, to various moulds, model, box-shaped part, housing part and big forging and casting etc. can rule and measure, can draw straight line, curve, circular arc line, vertical line, parallel lines etc., and can measure physical dimension, form and position tolerance etc., and line and the size of measuring are big, and scope is wide, the efficient height, full machine is the branch body structure, can dismantle, and is convenient to transportation and installation.

In the prior art, than the planer-type that has early, bridge-type or horizontal three coordinates line measuring machine, recently single arm type line measuring machine comes out, see the cantilevered three coordinates line measuring machine (application number: 91222807.5) of having authorized, owing to be the single armed one-piece construction, size is restricted (Fig. 1 shows), the Y direction cantilever can not do oversize, because the distortion that the deadweight of semi-girder causes is directly proportional with 4 powers of length, so it is line and the Y that measures can not be excessive to size, owing to being one-piece construction, non-dismountable again, make troubles for transportation and packing, the efficiency of measurement of single arm type is also lower.

The purpose of this utility model is to eliminate above-mentioned shortcoming, and track base and worktable are separated, and single armed becomes both arms, and each single armed can rule separately and measure, and data are handled by stand-alone computer, use as unit.Also can work simultaneously by two single armeds, computernetworking, dual-machine communication by Computer Processing, uses as complete machine in uniform data to a coordinate system that two single armeds are gathered.

Fig. 2, both arms separate type three coordinates line measuring machine front view

The utility model embodiment (Fig. 2 shows) is made up of worktable (1), guide rail (2), slide plate (3), column (4), column slide plate (5), cantilever (6), cantilever slide plate (7).Worktable (1) is independently, is respectively equipped with track base (8) in the both sides of worktable (1), and a cover guide rail (2), slide plate (3), column (4), column slide plate (5), cantilever (6), cantilever slide plate (7) are set respectively on the track base (8).Each single armed can rule separately and measure, and data are handled by stand-alone computer, uses as unit, and its principle of work and cantilevered three coordinates in the documents measuring machine of ruling is identical.Also can work simultaneously by computernetworking by two units, with in uniform data to a coordinate system of two units by Computer Processing, promptly use as complete machine.Worktable (1) is the reference plane of complete machine, and worktable (1) and track base (8) can be monoblocks, also can be spliced by several piece, and size is fixed by the size of measured piece, and worktable in the present embodiment (1) is of a size of 8 * 2 * 0.35 meter ³, track base (8) is of a size of 8.5 * 0.5 * 0.6 meter ³Three coordinate X of this machine, Y, Z sets up a cartesian corrdinate system at whole measurement space, accurate guide piece and detection system all are housed on each coordinate, measured workpiece is placed on the worktable (1), with the digital display meter zero clearing, when line and measurement, gauge head or scriber are moved on on the test point, the X of this point, Y, the Building Z scale value just shows by digital display device, send into microcomputer and carry out data processing, its result of calculation just shows automatically to be printed and drawing, can measure physical dimension and form and position tolerance and can draw various straight lines and curve, because both arms can be measured simultaneously, so efficient height, it is big that the size of worktable (1) can be done, can be contour during installation with ground, and automobile, big part such as tractor can directly get on to measure.

Much large molds and member and automobile etc. were not measured to facts have proved the utility model appearance, or manually climb up to climb down and measure with simple tool with ladder, not only labour intensity is big, work efficiency is low, and degree of accuracy is not high, can measure precise information efficiently now, and print and draw figure automatically and can forever preserve, its individual event precision is X to ± (0.05+L/40000) millimeter, Y to: ± 0.16 millimeter, Z to: ± 0.16 millimeter, improve more than the work efficiency twice than traditional manually the detection with simple tool.
