For the desk-top many functions of use of clearer statement case, method and the scope of application roughly, now briefly introduce several typical usings method with combined compasses.

One, the Tuo Yuan technique of painting:

1. the technique of painting of known ellipse long and short shaft radius: cross centre line and provide the major and minor axis radius draws, or only provide major axis one side radius, the major-minor pin directly measures minor axis radius, regulate two-way angle adjustable sliding sleeve, unclamp adjustment screw, main pin is aimed at heart point, and to the major axis lopsidedness, aim at the major axis radius end points until secondary pin, the revolute pair pin can obtain accurate ellipse.

2. the technique of painting of known ellipse short shaft radius and angle: the amount minor axis radius, regulate the angle adjustable sliding sleeve to required angle, main pin is aimed at heart point, and the revolute pair pin can be drawn this ellipse.

3. known minor axis radius, the technique of painting of angle and side angle: the amount radius, regulate main pin to required angle and to the minor axis lopsidedness to required angle, main pin is aimed at heart point revolute pair pin and is got final product.Example one ellipse short shaft radius 40mm, 45 ° of angles, and to 15 ° of minor axis lopsidedness.

Measure minor axis radius 40mm, regulate main pin to 45 ° of major axis lopsidedness, tilt 15 ° to minor axis, main pin is aimed at heart point, and the revolute pair pin gets final product.

Two, the technique of painting of surperficial right angle in pipe (post) and pipe and circular cone, plane, inclined-plane etc. and arbitrarily angled crossing surface intersection line:

1. the technique of painting of isometrical right-angle tee pipe: this type of intersection of all chances, can be earlier with the pipe surface quartering according to a conventional method, case is desk-top many with the extraction of combined compasses cross bar, load onto the vernier scribe head, can haul out surperficial bisector, wherein two of symmetry is center line, and two is terminated line and inspection line in addition, also can according to circumstances only haul out wherein three or two, even not drag bisector.Then according to the diameter of pipe, the clamping height, cross bar, main pin height and horizontal level are regulated in heart point position, measure the pipe radius, main pin perpendicular alignmnet heart point, and, make main pin be in the tram with secondary pin and the verification of both sides inspection line.(also can use square) revolute pair pin can be drawn a top-cross line of the whole or standpipe of transverse tube, and the opposite side of standpipe only needs 180 ° of standpipe upsets, draws by above step to get final product.

2. the isometrical arbitrarily angled threeway surface intersection line technique of painting: such threeway and the right-angle tee technique of painting are basic identical, it is consistent just standpipe axis angle to be adjusted at main pin inclination angle, main pin is aimed at heart point, draw behind transverse tube intersection and the standpipe one top-cross line, the standpipe tune is also overturn 180 °, and the opposite side intersection draws.

3. isometrical 120 ° of threeway surface intersection line techniques of painting: the amount radius, regulate 60 ° at main pin inclination angle, main pin is aimed at heart point, the revolute pair pin, the preceding intersection that draws, 180 ° of (main pin direction is preceding) upsets, the opposite side that draws, all the other two joints and the last joint technique of painting are identical.

4. the technique of painting of two joint elbow bend surface intersection lines: the amount radius, main pin perpendicular alignmnet heart point, the revolute pair pin is drawn to the both sides terminated line, overturns 180 °, and whole intersections draw.By this intersection cutting and welding, can obtain accurate elbow bend.

5. two joint and the techniques of painting of the arbitrarily angled elbow surface intersection line of more piece: it is determining of main pin inclination angle that such elbow is drawn main points, and intersection angle with pass, main pin inclination angle is before and after it: preceding intersection angle forever greater than after the intersection angle.

The intersection angle is asked main pin inclination angle before known: main pin inclination angle=(90 °-preceding intersection angle) ÷ 0.5

Known back intersection angle is asked main pin inclination angle: main pin inclination angle=back intersection angle ÷ 0.5

Equally, as long as know main pin inclination angle, intersection angle before and after formula also can be poured out easily in view of the above.

4 joint 90 ° of elbows (dried shrimp waist) surface intersection line techniques of painting: the amount radius, regulate main pin inclination angle: 75 ° of preceding intersection angles (15 °), ÷ 0.5=30 ° of main pin inclination angle=(90 °-75 °).Main pin is aimed at heart point, the revolute pair pin, and the opposite side intersection is drawn in tune and overturn 180 ° behind the top-cross line that draws.Its excess-three joint is analogized.

6. the not isometrical right angle and the arbitrarily angled threeway technique of painting: such is more isometrical simple, and transverse tube can not drawn bisector, and the technique of painting is with reference to the isometrical right angle and the arbitrarily angled threeway technique of painting.

Though the utility model using method is extremely many, basic skills is similar, and the utility model is simple to operate, as long as can apply in a flexible way, a lot of knotty problems all can be readily solved.

The utility model is compared the great scope of application that enlarged with traditional compasses with other sleeve type ellipsograph class, also make former serve very thorny technical problem become thundering simple, accurately, directly perceived, drafting and calibration as the inclined-plane circle, the drafting of isometrical arbitrarily angled threeway surface intersection line etc., general expert personnel have at least also want half an hour under the situation of data more than, precision also far can not guarantee.Use how this case is desk-top then only needs a few minutes with combined compasses, precision is also higher, and gathers multi-function in integral whole.The utility model practicality, wide, the easy and simple to handle easy grasp of the scope of application, simple in structure, make easy, cheap.
