Two, the reference coordinate with the workpiece main body is calibrated to consistent with the coordinate XYZ of lining instrument 14; Utilize three jack calibration workpiece that suitably distribute, make the workpiece design basis consistent, make workpiece design basis and YZ plane unanimity consistent with lining instrument XZ plane with calibration rotary disc alignment workpiece with lining instrument XY plane.Calculating in the time of can simplifying line like this improves the line quality;
Three, the calibration rotating disk is rotated in calibration rotating disk zero clearing, makes the coordinate system XZ plane of the inclined-plane that will rule or curved surface and lining instrument 14 vertical; Rotate the calibration of three-dimensional chalker and turn 7; Make scribe head on newly-established YZ ' plane or YX ' plane parallel with the inclined-plane that will rule or curved surface, move X and the Z axle of three-dimensional chalker, make scriber pass through the coordinate points that will rule and lock X and the Z axle; And the three-dimensional chalker can only be moved on the Y axle; Rotate the scriber fixed head, scriber is moved in a plane of newly-established X ' YZ ' coordinate system, thereby mark satisfactory space oblique line.The zero clearing of calibration rotating disk is after making the workpiece design basis and lining instrument XZ plane and YZ plane being consistent; The angle value zero clearing; With the inclined-plane that makes things convenient for workpiece or the adjustment of curved surface angle in horizontal plane, turn and 7 make the space oblique line on the curve surface of workpiece be in correct scribing position through rotating calibration rotating disk and the calibration that rotates the three-dimensional chalker.Move the Y axle and scriber 1 is implemented in stroke space oblique line action on the curve surface of workpiece in the combination of actions of the paddling on the curve surface of workpiece.
Like Fig. 2 is the structural representation of the utility model embodiment; It among the figure an irregular shaped piece; X among the figure; Y, Z are three reference axis of part, and what will solve is when marking part main center line, the processing line position line, to mark the center line (cd) of boss and the processing line (ab) of boss B face respectively with the three-dimensional chalker at present.
Like Fig. 2, Fig. 3 and shown in Figure 4, they all relate to two space angles, 35 degree and 10 degree the processing line (ab) of center line among the figure (cd) and boss B face.Earlier be supported on the workpiece main body on the calibration disk operation platform of horizontal positioned, with jack according to the X that demarcates among the workpiece figure, Y; The Z axis calibration arrives the X with the three-dimensional chalker, Y, and the Z axle is consistent; The A face is following, and the index dial zero clearing turns over 35 degree to the calibration rotating disk and makes boss B face vertical with three-dimensional chalker XZ plane; As long as at this moment make scriber two through the central point O center line (cd) that in the YZ plane, just can draw; Turning the calibration of three-dimensional chalker 7 turns over 10 degree and makes the scriber plane of motion parallel with boss B face again, and the coordinate points that adjustment three-dimensional chalker X, Z coordinate make scriber one demarcate through drawing locks lining instrument X, Z reference axis; Move the Y axle, at this moment scriber is once the processing line that can mark boss B face (ab).
A kind of scribble method of on curved surface, drawing the space oblique line may further comprise the steps:
One, be supported on the workpiece main body on the calibration rotating disk of horizontal positioned with jack; Utilize three jack supporting workpieces that suitably distribute; Can calibrate the line benchmark of workpiece short transverse easily; And it is steadily reliable that workpiece is settled, and utilizes the calibration rotating disk can do the calibration of horizontal plane interior lines benchmark easily to workpiece, makes things convenient for the adjustment of angle in the horizontal plane.
Two, the reference coordinate of calibration workpiece main body is to consistent with the coordinate XYZ of lining instrument 14; Utilize three jack calibration workpiece that suitably distribute, make the workpiece design basis consistent, make workpiece design basis and YZ plane unanimity consistent with lining instrument XZ plane with calibration rotary disc alignment workpiece with lining instrument XY plane.Calculating in the time of can simplifying line like this improves the line quality.
Three, calibration rotating disk zero clearing; Rotate the calibration rotating disk, make inclined-plane or the curved surface that to rule vertical, rotate the calibration of three-dimensional chalker and turn 7 with the coordinate system XZ plane in the lining instrument 14; Make scribe head on newly-established YZ ' plane or YX ' plane parallel with the inclined-plane that will rule or curved surface; Move the X and the Z axle of three-dimensional chalker, make the coordinate points of scriber, and the three-dimensional chalker is moved on the Y axle through ruling; Rotate the scriber fixed head, scriber is moved in a plane of newly-established X ' YZ ' coordinate system; The zero clearing of calibration rotating disk is after making the workpiece design basis and lining instrument XZ plane and YZ plane being consistent; The angle value zero clearing; With the inclined-plane that makes things convenient for workpiece or the adjustment of curved surface angle in horizontal plane, turn and 7 make the space oblique line on the curve surface of workpiece be in correct scribing position through rotating calibration rotating disk and the calibration that rotates the three-dimensional chalker.Move the Y axle and scriber 1 is implemented in stroke space oblique line action on the curve surface of workpiece in the combination of actions of the paddling on the curve surface of workpiece.
Four, the X axle of adjustment three-dimensional chalker and the coordinate of Y axle, make (X, Z) coordinate is on the point of oblique line, and locked again X axle and Z axle repeat above-mentioned action, thereby mark very long accurate space oblique line.
Fig. 5 is that A hole and B hole project to X, the size relationship figure's behind the Z plane, (actual A hole and B hole end surface do not need the plane parallel with XZ) now will be according to size and angle among the figure line of centres in A hole and B hole that draws.Among the figure between two holes distance far away, and when line scriber commonly used be 80mm to 150mm, obviously all locked when X axle and Z axle, by mobile Y axle, scriber one all can't once mark the two hole lines of centres.Rule as long as just can address this problem with the three-dimensional chalker according to following steps.Specific as follows: as to turn at calibration and 7 to mark the coordinate points (431.1 in A hole when being in 0 degree angle and an angle of 90 degrees respectively; 314.17), calibration turned 7 turn over 18 ° 18 ', move three-dimensional lining instrument X axle and Z axle; Make coordinate points locked X axle and the Z axle of scriber one through the A hole; Move the Y axle, mark the center oblique line at position, A hole, three-dimensional lining instrument X axle and the zero clearing of Z axial coordinate value; Move the X axle to calculate 1060 X tan18 ° 18 '=353.64 near position, B hole (such as 1060); Move Z axle to 353.64, repeat top line action then and just can mark the center oblique line at B position, can select marking lengths and shape and the length of selecting scriber according to the needs at line position when specifically ruling.Can mark various angles with this method, the center line of different length or processing line.
Through a large amount of production practices; Use this covering device; Cooperate the calibration rotating disk can be difficult to the curved surface that marks, the oblique line on the inclined-plane originally marking on mould and the foundry goods fully again, can mark space oblique line or processing line quickly and accurately through above method, and simple to operate; Flexibly; In a plurality of fields such as mould manufacturing, machining, panel beating workers very high value is arranged, solved the difficult problem that conventional method can't realize, very high value is arranged in a plurality of fields such as mould manufacturing, machining, panel beating workers.
