The traditional methods of jaw crusher mechanism design are: graphic method and analytical method.

The parameterized two-way design system flow chart of the jaw crusher mechanism Fig1Flowchartofparameterized now takes the jaw crusher mechanism parameter design system as an example, and elaborates this method. The system is developed by using the high-level programming language Visual Basic6.0 combined with the three-dimensional CAD software Solidworks2001P1US and database SQL2000. The initial data is obtained through the established mathematical model, and the system is directly generated by Visual 2001Plus. The trajectory of the movement, analyzing the dynamic characteristics of the movement, thus becomes a positive design process. Then modify the insufficiency on the organization chart, and automatically save the improved data to the SQL database.

Perform motion analysis again until the plan is satisfactory. Some Guo Nianqin of the crusher, etc.: The parameterized bidirectional design parameters of the compound pendulum jaw crusher mechanism are replaced by variables, and the parametric design application program is obtained. This becomes the reverse design process. This two-way design process greatly improves design efficiency, reduces design difficulty, and shortens design cycles.

(5) Parameter extraction module. Extract the modified parameters in the organization diagram.

(6) Parameter saving module. Save the modified parameters to the data 2 jaw crusher mechanism parameterized two-way design system composition of the jaw crusher mechanism parameter design system as shown, the function of each module is as follows: (1) system interface module. It is used to display and collect the specific parameters required for the design of the jaw crusher mechanism parameters, such as the feeding port width, the discharge opening width, the suspension height, the length of the bracket, the transmission angle, the eccentricity, the angle of the jaw, and the length of the moving jaw. The database provides default values ​​and collects structural parameters for years of development and design of the crusher for designers.

(2) Mechanism parameter calculation module. According to the user input parameters of the interface module, the mechanical parameters of the jaw crusher are calculated according to the mathematical model of the kinematics of the crusher.

(3) Mechanism diagram generation module. A schematic diagram of the CAD software generation mechanism is driven based on the calculated institutional parameters.

(4) Solidworks software interface module. Provides all functions that communicate with the 3D CAD software on the OLEAutomation layer. The CAD software application interface API) functions are encapsulated in the form of a class that is used to drive the CAD software to generate entities when generating the schema diagram.

In the library.

(2) Motion analysis module. According to the modified parameter generation mechanism sketch, the motion trajectory and motion parameters of each point on the jaw crushing maneuver are analyzed by the motion analysis software COSMOS/Motkm.

3.2 Operation of the form The system mainly provides the default parameter of the mechanism according to the traditional experience of the jaw crusher. The mechanism diagram is generated in Solid works, the mechanism parameters are modified in the diagram, and the modified parameters are used for movement. analysis. The specific operation process is as follows: Stepl. Click the fine crushing series or the medium crushing series button, select the model of a crusher in the list box, and the traditional experience data will appear in each text box. If the designer wants to design a new type of crusher, click Add and enter the appropriate parameters in each text box.

Step2. Click the Generate 2D Graph button to enter the Solidworks work interface and automatically generate a schematic diagram of the mechanism in which the parameters can be modified.

The modified parameters are displayed in the text box.

Plug-in COSMOS / Motkm work interface. In which the displacement, velocity, acceleration, motion trajectory, etc. of each point of the various motion parameter mechanisms of the mechanism can be obtained. As shown.

SteP5. Click the result analysis button to get the displacement and its characteristic values ​​of each point in the horizontal and vertical directions of each point on the movable jaw. As shown.

Motion analysis of compound pendulum jaw crusher mechanism Key technology of parameterized two-way design system of jaw crusher 4.1 API of three-dimensional mechanical CAD software Almost all three-dimensional mechanical CAD software has API port. The API is an OLE Automation-based programming interface that contains hundreds of function functions that provide programmers with direct access to 3D mechanical CAD software, which can be invoked by programming languages ​​such as VB, VC/C++, etc. The second development of 3D mechanical CAD software.
