By conical head, an employing AutoCAD2010 version with tangential nozzle, be compiled as example and illustrate the present invention below.
Can first skeletonizing, sketch drafting be take detail of design as according to Object Snap node and end points are set; Drawn after sketch by AutoCAD command execution following steps:
The 3-D view of execution view → overlook, main looking The axle sides such as axle side, the southeast are waited in southwest ..., foundation has the three-dimensional plot of the conical head 1:1 of tangential nozzle, as shown in Figure 3, specifically comprises:
Carry out the order of drawing → straight line, draw straight line;
Carry out the order of entity → cone, take described straight line as position line draw circles cone;
Execution drawing → entity → dissect order, cuts away the top of described cone, and then forms described conical head;
Carry out modification → delete command, delete the auxiliary cutting plane while drawing described cone;
Carry out the order of drawing → entity → right cylinder, draw out and take over 2;
Carry out modification → rotate command, assigned base point rotates described adapter 2, makes described adapter 2 rotate to the tangential angle of described conical head 1;
Utilize Boolean calculation function, carry out the order of modification → solid editing → union, select conical head 1 and take over 2, they are combined into an assembly, obtain joint line;
Execution modification → solid editing → take out shell order, selects described conical head 1 and takes over 2 and edit by drawing equipment wall thickness, tries to achieve adapter 2 and conical head 1 junction inside and outside wall and obtains respectively intersection;
Execution view → visual style → truly, obtain the three-dimensional effect diagram of described assembly.
In whole editing process, can use at any time 3d dynamic view device to check its three-dimensional effect diagram from different orientation;
With reference to Fig. 4, decomposition and combination body: select described assembly, it is divided into conical head 1 and takes over 2 two parts, obtain respectively described conical head 1 two end faces circle (two large small end faces circles of top end face circle and bottom end face circle), take over 2 and the intersection of adapter inside and outside wall and two groups of perforate intersections of conical head 1 inside and outside wall of conical head 1 junction, inwall perforate intersection 3 and outer wall perforate intersection 4, and the end face circle of taking over 2;
Carry out modification → copy command, copy described adapter 2;
Carry out drawings → point → fixed number wait minute order, the top end face of described conical head 1 is round and bottom end face is round and take over 2 end face circle is divided into many equal portions, the described conical head 1 of take is respectively starting point with the end face circle Along ent of taking over 2, take their intersections separately as terminal picture bus, the plain line that the bus of described conical head 1 and adapter 2 forms intersects respectively their intersections separately, the order of execution view → 3d dynamic view device;
Described plain line is clicked successively, and the order of executing means → inquiry → distance, obtains the line segment length for setting-out.Or by Function for Dimension, also can obtain the line segment length for setting-out; Line segment for setting-out described herein comprises be always or usually as specified line, outline line and boost line.
The above-mentioned line segment for setting-out is drawn at grade successively, be generally plotted on model, if Fig. 5 a and Fig. 5 b are the interior template drawings of conical head 1 tapping intersection, Fig. 6 is that other line segments that setting-out obtains feed back to the figure that conical head 1 obtains.The object that expansion setting-out reaches material saving and accurately locates by technological requirement labeled with pertinent information.
Model has different forms because of the difference of using, and conventional have outsourcing model, a built-in model and flat material model.The material of sample making generally adopts galvanized sheet metal or color steel.By the full-time Quality Inspector of factory, checked, and make record;
Opening-nozzle place mainly with conical head thickness of slab, to take over thickness of slab relevant with position while welding, the mode of groove is to pass through solid figure, third-class relation and position relation between three-view diagram, with reference to two groups of intersections inside and outside solid figure, do the position groove design of interface, utilize groove to form correct Interface Shape.
Intersection model precision is to change by suitable view, finds out the perforate position line that relation line and straight line are expressed, and uses automatic marking function, just can obtain the line segment length for perforate setting-out; According to 1:1 scale intersection model, guaranteed perforate location intersection model precision.
The application of model: the one, the many boost lines while avoiding expansion setting-out are all drawn on steel plate; The 2nd, model can jacking row be schemed on steel plate, and material is fully used.Except the expansion model that blanking is used, when detecting the plate-form gauge of degree of crook while being shaped in addition and assembling, detect the assembly model of relative angle, mutual alignment.Model has different forms because of the difference of using, and conventional have outsourcing model, a built-in model and flat material model.
The line segment that acquisition is used for to setting-out, at sample lining out, is made distinguishing mark; Inside and outside intersection with reference to conical head and adapter during on-the-spot perforate cutting carries out groove cutting;
Take over installation check.
The D modeling function of this expansion setting-out method application AutoCAD directly obtains intersection, do not need to study projection relation and skill, just can obtain expanding data, various geometric relationships just can be very clear, in the setting-out of tangential nozzle perforate precision, the method has broken through the setting-out patterns such as traditional graphing method, computing method, Y-factor method Y, improved quality and the efficiency of sheet metal setting-out, made the expansion of complex structural member become simple, clear, required data accurately and reliably.It is a kind of new efficient expansion setting-out method that is better than traditional setting-out pattern.Device aperture and adapter are installed once success rate and are reached 100%, have realized the object that high precision is controlled.At CAD, apply today more and more widely, a kind of setting-out pattern being worthy of popularization.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
