Embodiment
In the present embodiment, a kind of product automatic assembly design system based on Pro/E is in the product design for carrying out Parameterization Model Design and model assembling for different designs demand; Parameterization Model Design comprises Parameter part design and parametrization part design, in the present system, still there is the non-parametric model be made up of imparametrization part and imparametrization parts, model assembling can be the assembling between arbitrary parameter model and non-parametric model, see Fig. 1, automatic assembly design system composition comprises: individual client and the shared data bank being provided with Pro/E software of n; Shared data bank realizes the data storage facility of collaborative work as multiple client; N client, under the support of shared data bank, can realize collaborative design.
Comprise in shared data bank do not complete part tasks item by several and do not complete that part tasks item do not complete that Parameters of The Parts item forms one to one with several do not complete parts list, what completed part tasks item by several and completed that part tasks item completed that Parameters of The Parts item forms one to one with several completes parts list, product composition table, configuration his-and-hers watches, configuration interface his-and-hers watches, configuration constraint table and interface table, wherein not completing parts list and having completed parts list provides Data support for parametrization workstation, product composition table, configuration his-and-hers watches, configuration interface his-and-hers watches, configuration constraint table and interface table provide Data support for mounting work station,
The composition of any one client comprises model bank, parametrization workstation and mounting work station, during system works, parametrization workstation and mounting work station work alone, and the two does not produce mutual interference, and model bank is that parametrization workstation and mounting work station supply a model and support;
Model bank provides required model for system, and the model in model bank is divided into the parameterized model needing to carry out Parametric designing and the non-parametric model not needing to carry out Parametric designing according to design requirement; Parameterized model is divided into Parameter part and parametrization parts, and non-parametric model is divided into imparametrization part and imparametrization parts; This kind distinguishes the Parameter Function Unit just in order to model is described, in fact, in systems in which, all primary entities is there is in all parameterized models and non-parametric model in model bank, only parameterized model is relative to having receiving parameter design objective and parameter non-parametric model thus carrying out the function of Parametric designing, and non-parametric model there is no this function;
Parametrization workstation is in order to drive the Parametric designing of part and assembly; Its composition comprises timer, task distributor, central parameterized treatment device; Because in the product design of reality, may can produce a lot of Parametric designing task within the regular hour, the effect of timer is just can by numerous Parametric designing task piecemeal process, thus the chaotic problem of the process avoiding task too much to cause; And due to the realization of Parameter Function Unit can only be logically the corresponding task of a program process, therefore, even the Parametric designing task of piecemeal is when giving central parameterized treatment device process, still need in advance by the Parametric designing task of piecemeal and process one_to_one corresponding, this just needs task distributor to realize;
Mounting work station is in order to drive the automatic assembling of part and assembly, and its composition comprises interface definition module, products configuration module, assembling detection module and central authorities' assembling processor; Interface can be regarded as a subcharacter of part in Pro/E software, such as, a material object parts is made up of a lot of face, and so these faces just can be considered as the subcharacter of this part, all can define interface corresponding to each subcharacter by interface definition module; In the product design work of reality, design requirement often can not once just can be determined, need constantly repeatedly to revise, for the feature of this product design, the effect of products configuration module is just that it can adapt to different design requirements, realize flexible configuration, thus provide support for formation product completed; In model assembly operation in Pro/E, after all being all the subcharacter of operation component part, is also interface, therefore, whether realize assembling automatically to exist with regard to needing to detect these self-defining interfaces before assembly manipulation, this function is just realized by assembling detection module; Only have detection to obtain all self-defining interfaces all to exist, could central authorities' assembling processor be transferred to process corresponding products configuration information;
Timer in any one client is cycle T not completing parts list to read successively and not complete part tasks item described in several and do not complete Parameters of The Parts item from shared data bank at regular intervals, and several reading are not completed part tasks item and does not complete Parameters of The Parts item and carry out the part bag that do not complete of packing in formation period of time T and send to task distributor, task distributor by received period of time T do not complete in part bag several do not complete part tasks item and do not complete Parameters of The Parts item and send to central parameterized treatment device successively according to reading order, it should be noted that period of time T setting can not excessive can not be too small, T crosses conference and causes once reading of task too much, thus causes process chaotic, and the too small meeting of T causes once reading of task very few, is difficult to the effect playing parametrization workstation,
Central authorities' parameterized treatment device receives several successively and does not complete part tasks item and do not complete Parameters of The Parts item and automatically perform Parameter part design successively, obtain several Parameter parts and be stored in model bank, driven by several Parameter parts and automatically upgrade with all parts of its subordinate, thus realize parametrization part design; Meanwhile, central parameterized treatment device by part tasks item corresponding respectively for several Parameter parts and Parameters of The Parts item successively stored in completing in parts list; Thus the Parameterization Model Design completed in a period of time T;
Described interface definition module is transferred several Parameter parts corresponding and imparametrization part according to design requirement and to be gone forward side by side line interface definition from model bank, thus several part interfaces completing each Parameter part and imparametrization part add, and the part name of several Parameter parts and imparametrization part and corresponding all part interfaces are stored in the interface table of shared data bank; Form part name and the part interface relation one to one of Parameter part and imparametrization part; It should be noted that, the definition of interface can only be carried out for part, and the part defined in interface definition module both can be Parameter part also can be non-Parameter part, and each part also can define multiple interface simultaneously;
Products configuration module reads the title of all parameterized models and non-parametric model from model bank, and selects parameterized model title or the non-parametric model title of composition product according to design requirement, forms product composition table; Without the need for fixing order in product composition table, as long as comprise all model names of composition product in table;
Products configuration module is configured setting to the parameterized model title in product composition table or non-parametric model title, forms configuration his-and-hers watches; Configuration his-and-hers watches comprise parameterized model title or non-parametric model title and match mutually with parameterized model title or non-parametric model title mate part name; The mutual relationship that the effect of configuration his-and-hers watches is between designated model, this mutual relationship occurs in pairs, and configure right configuration sequence and do not need to preset.
Products configuration module, according to configuring his-and-hers watches query interface table and carrying out configuration interface to setting, forms configuration interface his-and-hers watches; The effect of configuration interface his-and-hers watches is that specified configuration centering contains certain interface of the part of interface mutually in pairs, and the subcharacter also namely belonging to certain part is paired mutually;
Products configuration module is arranged being configured constraint configuration interface according to design requirement, forms configuration constraint table; The effect of configuration constraint table is to specify the pair wise of the subcharacter belonging to certain part, such as, belongs to the face laminating type between the face of certain part and face;
Form table by interface table, product, configuration his-and-hers watches, configuration interface his-and-hers watches and configuration constraint table form complete products configuration information and be stored in shared data bank; When certain module of system needs read or write data, can read from corresponding table or write data, thus the corresponding relation of practical function and data;
Assembling detection module reads parameterized model title or the non-parametric model title of product from the product composition table of shared data bank, and in model bank, read the parameterized model title of product or the parameterized model corresponding to non-parametric model title or non-parametric model; It should be noted that this system does not need corresponding model to call in Pro/E software, so just can realize operation model under the condition not opening model from model bank during reading model;
Whether the interface of assembling detection module detected parameters model or non-parametric model lacks, if disappearance, then in interface definition module, again adds Parameter part interface or the imparametrization part interface of disappearance; Otherwise central authorities' assembling processor is according to products configuration information and the assembling that Processing Algorithm completes parameterized model or non-parametric model is automatically assembled in utilization; Thus realize the automatic assembling of product.In assembling product process, do not need manual intervention, thus greatly improve design efficiency.
See Fig. 2, a kind of assembling Processing Algorithm of the product automatic assembly design system based on Pro/E is the assembling automatically being completed parameterized model or non-parametric model in accordance with the following steps by central authorities' assembling processor:
Step 1: according to all part names in the interface table of products configuration information extraction shared data bank and corresponding part interface, thus form the parts list containing part interface; Because a part can define multiple interface simultaneously, therefore, in the parts list containing part interface, same part name may occur repeatedly;
Step 2: because part name same in the parts list containing part interface may occur repeatedly, so need compression containing the identical parts title in the parts list of part interface, make all part names in the parts list containing part interface not identical; Thus obtain the mark parts list with sole component title; This mark parts list in each part name only may occur once, but due to Data Source be now shared data bank, so, this mark parts list can't identify by Pro/E software;
Step 3: due to mark parts list can't identify by Pro/E software, therefore need by mark parts list change into the data layout that can identify in Pro/E software, obtain Pro/E identify parts list;
Step 4: in the product composition table corresponding to different design requirements, model name number can be different, so comprise m parameterized model title or non-parametric model title in hypothesis product composition table; Definition loop variable x; And initialization x=1;
Step 5: the xth model corresponding to an xth parameterized model title in product composition table or non-parametric model title is called in Pro/E software, thus can operate model entity;
Step 6: judge whether an xth model of calling in is part, if part, then extracts the title of an xth part; Otherwise an xth model of calling in is parts, but parts may comprise multiple part, so need to identify parts list according to Pro/E to obtain the title in an xth model of calling in the part of interface, be designated as the title of an xth part;
Step 7: according to the title of an xth part, query configuration his-and-hers watches, obtain the xth of matching mutually with the title of an xth part and mate part name; It should be noted that the model of xth coupling corresponding to part name may be part also may be parts;
Step 8: the model corresponding to an xth coupling part name may be part also may be parts, so need to judge whether the xth xth that coupling part name is a corresponding coupling part or the parts comprising an xth coupling part are present in product composition table according to an xth coupling part name, if exist, the parts then from model bank, xth being mated part or comprise an xth coupling part are called in Pro/E software, and the parts mating part by called in an xth model and xth or comprise an xth coupling part form an xth Matching Model pair; By an xth Matching Model to the corresponding xth of an acquisition configuration interface pair; And perform step 9; If do not exist, then the value of x+1 is assigned to x, and judges whether x=m sets up, if set up, then exit execution; Otherwise return step 5; It should be noted that by an xth Matching Model to obtain an xth configuration interface to being not necessarily present in configuration interface his-and-hers watches;
Step 9: due to an xth Matching Model to obtain an xth configuration interface to being not necessarily present in configuration interface his-and-hers watches, so need to inquire about an xth configuration interface respectively to whether being present in configuration interface his-and-hers watches from interface table, if exist, then perform step 10, if do not exist, then represent that an xth configuration interface is to disappearance, thus return interface definition module and again add an xth configuration interface pair;
Step 10: inquire about in configuration constraint table according to an xth configuration interface, obtains an xth configuration interface to a corresponding xth configuration constraint; And in Pro/E software, be converted to the right constraint of Matching Model, thus complete the right assembling of an xth Matching Model; And the completed assembled process of a product is made up of, so also need the completed assembled termination condition of clear and definite product assembling a lot of Matching Model;
Step 11, in order to judge when product reaches the state of completed assembled in an assembling process, and the value of x+1 is assigned to x, and judging whether x=m sets up, if set up, then having represented the assembling of described parameterized model or non-parametric model, and having exited execution; Otherwise, return step 5 and perform.
