【摘要】 为解决熔射制造大中型汽车覆盖件模具过程中人工研磨时间长、劳动强度大等问题,建立了面向熔射快速制模的机器人自动研磨系统。在该系统上进行机器人研磨工艺参数实验研究,得到了研磨角度、机器人行走速度和路径对研磨表面质量的影响规律;在此基础上选择合适的研磨条件,在通过等离子熔射制造的模具表面皮膜上进行了研磨实验。实验研究结果表明,保持适当的研磨压力,选取合理的机器人行走速度、研磨角度、进给量,可得到较好的研磨效果。该机器人自动研磨系统适用于熔射制造的模具及一般模具的研磨过程。更多还原

【Abstract】 When big or medium-sized autobody panel moulds are ground by hands,many problems,such as long grinding time and high labor intensity,should be thought about;thus this paper developed robotic automatic grinding system facing plasma spray tooling.Based on the system,a serials of processing experiments were carried out and the effects of grinding angles,robot moving speed and grinding path on the surface quality were studied and the suitable grinding parameters were obtained.By using the parameters robotic grinding experiments on the surfaces of the mould manufactured by plasma spay tooling were executed.The experimental results indicate: keeping suitable grinding pressure and choosing reasonable grinding angle,robot moving speed,feed rate,ideal surface quality can be obtained by adopting the established robotic grinding system and the platform can be applied in grinding process of the moulds manufactured by spray tooling and general moulds.更多还原
