Parameter changes a design to be operated handily quickly with its, in contemporary design the position with in making, was had very significant, the article uses the parameter of mechanical to tobacco built up fixture to change a design, related a specific example that uses SolidWorks 2003 software to undertake parameter changes a design simply. Nicotian machinery belongs to sheet small lot production, spare parts breed is much and form is complex, big to the demand of built up fixture. Use generally as numerical control machine tool and machining center, make full use of these costly equipment, make its full bear moving ability obtains good economic benefits, because this has tool quickly,manufacturing preparation becomes a conspicuous issue. Traditional special fixture prepares cycle because of its long, cost is high, cannot satisfy the need that the company grows more and more, and just of built up fixture suits place of this kind of production just about necessary art equipment. Design and assemble of built up fixture at present however still use backward spell outfit and administrative method artificially, efficiency low cycle is long, all these elements studied the CAD of built up fixture to mention a new significant position. Design to make the computer assists built up fixture more quick, convenient, must build warehouse of component of built up fixture. To seriation spare parts, if still use traditional design method, each measure the congener spare parts of likeness of different, structure has designing alone, its workload big, efficiency is low, design administration also greatly disadvantageous. Be aimed at this one problem, the author adopts project practice, use SolidWorks 2003 software, the parameter that realized component of built up fixture changes a design. One, alleged parameter changes basic design principle the design is to show parameter changes the dimension of the model to use corresponding relation to express, and do not need to use certain numerical value, change joins numerical value, will change all size related to it automatically, use parameter to turn a model namely, will revise and control geometrical appearance through adjusting parameter, realize the mathematical model of component automatically. 2, design method and process with the most commonly used rectangle foundation board (Z1110) for bright parameter changes formative course for the exemple, the graph is shown 1 times for its basic structure, this groups of component share 22, namely 22 norms, the Z111090 with the biggest norms in choosing this model above all undertakes building a model. Graph the basic structure of component of 1 clamping apparatus 1.

Design model: In configuration process, must line out the dimension of each parts. Dimension can be design dimension, also can be aleatoric dimension. With the function that adds geometrical significance, assure the central coincide of the height of center of side T chamfer and fundamental system. 2.

Rechristen feature: In scale when three-dimensional graph, the system names automatically for a feature, understand to make every feature intuitionistic, easy, had better have a significant name for the feature in component, itself of the component when can avoiding to design already so arises between each features promiscuous, also benefit is called at other, editor series part. For example will current name " matrix, drawing " should be " fundamental system " (1) is clicked " Feature Manager " in designing a tree " matrix, drawing " , play a quick menu. (2) clicks quick menu medium " attribute " option, shoot a diagnostic attribute dialog box. (3) is in of the dialog box " name " the name with the new input in casing " fundamental system " , click " affirmatory " . Also can be not in clicking a design to cultivate continuously " matrix, drawing " make name casing turns into can compile position, input new name can. Press this standard will other part is important diagnostic rechristen, for instance: Will " excise, drawing 1 " instead " horizontal T chamfer " ; Will " array (linear) 2 " instead " array of vertical T chamfer " ; Will " array (linear) 3 " instead " array of M12 whorl aperture " ; Will " lens to 4 " instead " lens of side T chamfer to " etc. 3.

Save component for " rectangular foundation board.

Sldprt " . 4.

Indication dimension: In F " Eather Manager " in designing tree option, right key is clicked " annotate " folder, choose " indication feature dimension " option; If want to be in among the model in the meantime,indication measure tag and dimension are worth, can click " tool " next pulling in menu " option " , below systematic option label, click " general " , choose next " indication measure tag " answer choose casing, click " affirmatory " . 5.

Rechristen dimension: Change the name of a few dimension, the hypostatic part that in realizing the name that uses measure to identify series cell, differs individually, serve as series part to design the caption in the watch with this name. Change the quantitative tag method of array of horizontal T chamfer: Doubleclick a feature to cultivate array of medium horizontal T chamfer with Zun Jian, in three-dimensional and hypostatic graph occurrence array amount is mixed name, click array amount with right key, play a quick menu, take " attribute " option; In size property dialog box, a new name is inputted in name casing " groove is counted " , click " affirmatory " by button. 6.

Change other dimension name with the law: Will " the quantitative tag of array of vertical T chamfer " (D1) instead " groove is counted " ; Will " the quantitative tag of underside groove array " (D3) also instead " groove is counted " etc. 7.

After inserting new series part design to express afore-mentioned jobs to finish, can build new series part to design a watch. (1) is clicked " insert " next pulling in menu " build series part to design a watch " , play piece build series part to design watch dialog box. Subsequently, a built-in Excel is versed in tabulation appears in the window. Designation of unit case A1 is versed in tabulation is series part to design a watch, model name is " rectangular foundation board " , the acquiescent name that unit case A3 is the first new configuration " the first example " . (2) is in the 2nd in, the input considers pilot parameter name (namely measure tag) , input method expresses unit case to be activation condition to hold proper job, a certain dimension is doubleclicked in graphical area, criterion measure tag and current ginseng numerical value are written into unit case. When continueing to increase parameter with this kind of method, case meets the unit of photograph adjacent be activationed automatically, add every parameter in caption travel, current numerical value shows in the 3rd in, increase the parameter of certain type quickly to the middle of the watch. (The configuration name in unit case of 3) changeable A3 (can replace with product name or model, this exemple is Z111090) . (4) is versed in in Excel tabulation inputs parameter to be worth in unit case, if the graph is shown 2 times,the series part that found designs a watch. Graph 2 new the series part that found designs a watch 8.

Indication configuration clicks window bottom " Configuration Manager " label, show in the left window case of the window already some configuration names. Doubleclick certain to configure a name, can show the part of this configuration. 9.

Rectangular foundation board if the drive model of the 3 norms Z111070 in series substance model, Z111075, Z111080 pursues show 3 times. Graph the drive model of 3 hypostatic models 3, the parameter that conclusion uses SolidWorks 2003 software to undertake seriation group places component changes a design, its design methodological editor, revise wait for very easy implementation. Can see clearly from afore-mentioned processes, parameter changes design and traditional design photograph to compare, the biggest characteristic is it stored design whole process, make project technology personnel can pass parameter of fluctuant and certain tie and need not alter the whole process that component designs will update a design. Become the edition that has model of initiative design, component to revise and a variety of plan designs and relative significant step. CNC Milling
