The utility model provides a four-throwing head turntable pressure-holding polishing machine, which relates to the technical field of mechanical equipment, and solves the technical problem that the linear feeding mechanism of the existing polishing machine consumes longer feeding time. The device comprises a plurality of feeding racks arranged in an annular manner, and a plurality of feeding racks can rotate around the axis of the annular geometric center; a plurality of workstations are arranged around the feeding rack, and fixture devices are arranged on the plurality of workstations for clamping the workpiece; at least one of the workstations is a loading/unloading workstation; and at least two workstations are provided with a polishing device and a throwing device. The polishing device is provided with at least two throwing heads, and the throwing head is also provided with a pressure retaining cylinder and a throwing wheel, which are used to provide stable pressure so that the throwing wheel is pressed on the surface of the workpiece during the working process. The pressure-holding polishing machine of the four-throwing-head turntable of the utility model has a number of feeding racks which can rotate around the axis of the ring geometric center, and can quickly transfer the workpiece out of the working area at one time, thus saving the feeding time.

技术介绍
抛光是指利用机械、化学或电化学的作用,使工件表面粗糙度降低,以获得光亮、平整表面的加工方法。是利用柔性抛光工具和磨料颗粒或其他抛光介质对工件表面进行的修饰和加工。抛光的工作一般在抛光机上进行,抛光机也被称为研磨机,常作为机械式研磨、抛光和打蜡。抛光机的工作原理是,电动机驱动安装于抛光机上的海绵或者羊毛抛光轮进行高速旋转,对工件进行抛光作业。抛光轮和抛光剂共同作用于工件表面进行摩擦,进而去除表面污染、氧化层和表面浅痕的目的。抛光轮的转速较高,一般在1500~3000r/min,不过实际的使用转速可以根据新要求的不同进行相应的调整。现有的抛光机功能相对单一,一台抛光机只能进行粗抛或者是精抛一项作业,当工件的表面粗糙度要求较高时,需要先在粗抛机上粗抛,然后将粗抛后的工件取下来夹在精抛机上,进行精抛,工序较多,增加了操作人员的工作量,工作效率较低。同时,现有抛光机的直线送料机构送料耗费的时间较长。本申请人发现现有技术至少存在以下技术问题:现有抛光机的功能单一,加工生产效率低。 ...
