Embodiment Construction

[0008] Embodiments of the present invention are described in further detail below:

[0009] It includes the following steps: A. Import the geometric model of the vehicle frame assembly to be drilled into the CAE analysis pre-processing software for grid division, establish a two-dimensional grid, and establish a corresponding grid on the surface of the two-dimensional grid to be drilled. Temporary node, this temporary node is the circular hole center of required drilling, input needs drilling parameter, described needing drilling parameter comprises aperture size, cobweb layer number, hole circumference node number; B, select all in step A For the temporary nodes of the required drilling position, write the simulation calculation program in TCL language, and import it into the HyperMesh software for simulation calculation, and obtain the temporary nodes as the center, with the input in step A and the required drilling parameters Consistent holes; C. Change to a different set o...

Abstract

The invention discloses a batched drilling method which comprises the steps that 1 a geometric model of a frame assembly to be drilled is imported into CAE analysis pre-prcessing software to conduct mesh generation process, corresponding temporary nodes are set up on a two-dimensional mesh surface which needs to be drilled, the temporary nodes are the centers of circular holes which need to be drilled, and drilling parameters are input; 2 all the temporary nodes of positions need to be drilled in the first step are selected, a simulation calculation program is programmed through TCL and imported into HyperMesh software to conduct simulating calculation, and the holes which take the temporary nodes as the centers and conform to the drilling parameters in the first step are obtained; 3 a group of different drilling parameters is selected to repeat the first step and the second step to obtain another group of holes of different drilling parameters. By means of the batched drilling method, the problems that an existing multi-hole part drilling process method is not convenient to use, the drilling efficiency is low, and the error rate is high are solved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a batch drilling method. Background technique [0002] When using finite element software for CAE pre-processing, it is often necessary to drill holes on the drawn two-dimensional grid. Especially when performing CAE analysis on commercial vehicle frames, there are many large and small holes, and various connecting plates, angle iron plates, longitudinal beams, beams, supports, etc. are connected by rivets or bolts. For problems such as hole position dislocation, leakage and missing holes, etc., it is necessary to adjust the hole position or re-drill in time during the analysis process. However, the latest version of CAE pre-processing software such as HyperMesh can only drill one hole at a time, and it is necessary to reset the parameters such as the hole size, the number of spider web layers, and the number of nodes around the hole every time before drilling, which is cumber...
