建立了洗瓶机喷针提升跟随系统的三维模型,通过将喷针提升和跟随的传动整合到同一根轴上,极大的减少了多个转盘占据的空间和重量。其中难点在于设计空间圆好柱凸好轮结构,画出凸好轮
摘要: 本课题研究的是洗瓶机喷针提升跟随系统结构,主要计算内容在于洗瓶机中心转盘传动结构和圆柱凸轮传动即提升系统中的零件选用和校核,圆柱凸轮曲线的计算。洗瓶机喷针提升跟随系统结构主要分两方面:一方面是提升伺服电机直接将动力传入齿轮箱,无减速比,仅改变动力传递方向,利用设备横向空间,降低设备高度,再通过滚珠丝杠将动力传至针架的支撑轴,使针架上下运动。另外一方面是,旋转电机直接将动力传入圆柱凸轮,再由和针架的支撑轴相连的摆臂实现针架的旋转。
其中,在结构设计中遇到了电机选择,凸轮曲线设计,齿轮的设计和滚珠丝杠螺母副的计算和选用。特别是丝杠螺母部分,通过其中的设计,完成了本设计关键的传动结构设计。本设计采用Inventor设计软件进行三维建模,方便产品的设计。

Design of Needle Lifting Follower System Structure for Bottle Washer
Abstract: The subject researches the structure of the sprayer boosting and following system of the bottle washer. The main calculation contents are the center drive structure of the bottle washer and the selection and verification of the components in the cylindrical cam transmission, ie, the lifting system, and the calculation of the cam curve. The structure of the sprayer booster following system of the bottle washer is mainly pided into two parts: one is to lift the servo motor directly into the gear box, there is no reduction ratio, only the power transmission direction is changed, the lateral space of the equipment is used, the height of the equipment is reduced, and then the ball screw is passed The bar transmits power to the support shaft of the needle holder, allowing the needle holder to move up and down. The other is that the rotating motor directly transmits the power to the cylindrical cam, and then the oscillating arm connected to the supporting shaft of the needle holder realizes the rotation of the needle holder.
Among them, encountered in the structural design of the motor selection, cam curve design, gear design and calculation and selection of ball screw nut pairs. Especially the screw nut part, through which the design completed the design of the key drive structure design. This design uses Inventor design software for 3D modeling to facilitate product design.
