The invention discloses a UG CAM-based automatic programming plug-in for fine milling of a chain wheel and chain nest of a mining scraper conveyor. The plug-in design comprises the following steps ofdeveloping a CAM system, designing and realizing a dynamic link library structure, and designing a system interface. The advantages of the invention are that: the operation process is simple, the setting of universal parameters in numerical control programming is shielded, the numerical control programming efficiency of a chain wheel is improved, the knowledge level requirement on an operator is reduced, corresponding milling process parameters such as the radius of a cutter, the rotating speed of a main shaft, the feeding speed and the step pitch can be directly selected in a plug-in interface, and one-key NC code generation is realized; on the basis of structural characteristics of the chain wheel and numerical control machining process analysis, the one-time chain nest forming method based on variable-axis curved surface contour machining is provided, and the problems that according to a common numerical control machining method, the NC code quantity is large, and the machining efficiency is low are solved.
Description
technical field [0001] The invention belongs to the technical field of coal mine mechanized mining, in particular to a UG CAM-based automatic programming plug-in for precise milling of chain wheel and chain pockets of mining scraper conveyors. Background technique [0002] Coal mine mechanized mining mainly relies on scraper conveyors for loading, unloading and transportation. As a typical circular chain transmission mechanism, the mining scraper conveyor drives the scraper chain to move circularly through the drive sprocket to send the ore out. Among them, the sprocket is the main driving part of the conveyor. In addition to transmitting the huge torque generated by the power source, it also bears a large alternating and impact load during the meshing process with the circular chain. The working environment of the mining conveyor is harsh. When the sprocket and the chain ring mesh, they often come into direct contact with sand, gravel and coal slag, which can easily lead t...
