PAGE 第PAGE IV页 辽宁科技大学本科生毕业设计 PAGE 简易石材磨光机系统设计 摘要 传送带式石料磨光机就是专门用来磨削加工石料表面并最终获得准确尺寸和光亮美观表面的板材墓碑石和拼花石的一种机器设备。它在磨头升降和加压控制，以及传送带驱动两个装置中，采用了液压传动系统。它的基本结构分为上下两大部分。上部包括四组磨头，每组磨头由单独的电机经三角皮带轮驱动主轴旋转，机器下部包括由许多链板组成的传送带，以及送料和出料装置。电机经链条驱动链轮带动传送带作反时针方向运动。被加工的石料板坯，由右端的送料装置连续送人传送带上，经过四组磨头的磨削加工，达到预定的尺寸和光洁度以后，由左端出料装置上取出，成为合格产品。根据设计任务书的要求，本设计说明书针对石材磨光机进行设计说明。主要内容包括简易石材磨光机结构设计；电机功率的计算与确定；液压系统的组成、工作原理、液压系统参数、拟定液压系统图；液压元件的计算及选择，包括液压缸、液压阀、油箱容积、压力损失、发热与温升等相关计算。 关键词：磨光机、液压、设计 Simple stone material polishing engine system design Abstract The transmission belt type stone material polishing engine is uses for the abrasive machining stone material surface specially and finally obtains the accurate size and luminous artistic surface plate tombstone Shi Hepin the rocks and flowers one kind of machine equipment.It in the wheelhead fluctuation and the compression control, as well as the conveyer belt actuates in two equipments, has used the hydraulic actuation system. About its basic structure divides into two major parts.Upside including four groups of wheelheads, each group of wheelheads actuates main axle revolving by the independent electrical machinery after the v-belt pulley, lower part the machine including the conveyer belt which is composed by many link joints, as well as feeding and material installment.The electrical machinery actuates the chain wheel impetus conveyer belt after the chain link to make the counter-clockwise direction movement.Stone material tube blank which processes, sees somebody off continuously by the right margin feeding equipment on the conveyer belt, passes through four group of wheelhead abrasive machinings, achieved after predetermined size and smooth finish, takes out by the left side material installment in, becomes the certified product.According to the design project description request, this design instruction booklet carries on the design explanation in view of the stone material polishing engine.Primary coverage including simple stone material polishin
