如图1至图5所示的一种圆筒类内螺纹零件油垢清除设备包括：机箱本体1、清洗机构2、龙门支架组件20、支撑腿200、横梁201、安装架202、第一X轴丝杠组件203、第二X轴丝杠组件204、第一基座205、第二基座206、第一安装座207、第二安装座208、行程气缸209、第一伺服电机2010、第二伺服电机2011、转轴21、轴承座22、驱动马达24、蒸汽喷嘴250、螺旋形刷体251、电动伸缩结构252、圆形微动电机2520、伸缩管2521、螺杆2522、铰接座26、液压伸缩杆27、内腔28、法兰组件29、传输线3、油垢收集装置4、蒸汽发生装置5、气管6、导流罩7、导流口70、圆锥形入口71、托盘8、Y形托架80。
该装置适用于废旧机器翻新产业，其中机箱本体1的底部设有多个支撑组件，机箱本体1采用铝合金材料制成，清洗工位2固定安装在机箱本体1的内部，传输线3贯穿在机箱本体1且位于清洗工位2的下方，油垢收集装置4固定安装在机箱本体1下方。进而清洗工位2可对传输线3上传送来的零件进行检测和清洗操作，实现零件的全自动清洗。
相对于传统的采用高压水枪喷淋的清洗结构，本发明中所述清洗工位包括：固定安装在机箱本体1中的龙门支架组件20，固定安装在龙门支架两侧且与蒸汽发生装置5连通的气管6，对称安装在龙门支架两端的上的清洗组件，以及套接在龙门支架外部的护罩；所述护罩的两侧设有光栅传感器。进而龙门支架上的清洗组件可直接从传输线3的两侧对零件进行清洗；护罩的两侧设有的光栅传感器可对零件的尺寸以及运行的位置进行检测，并将检测数据发送至控制系统。
进一步的，圆筒类内螺纹零件在传输过程中通过托盘8在传输线3上传送，为了避免清洗出来的油垢污染托盘8，避免对托盘8的重复清洗，采用将圆筒类零件轴线与传输线3垂直的摆放方式，进而使圆筒类零件内径口两端的横截面与传输线3在同一平面内；所述龙门支架组件20包括：固定安装在机箱本体1上的四个支撑腿200，固定安装在支撑腿200上的横梁201，设置在横梁201两端的第一X轴丝杠组件203和第二X轴丝杠组件204，以及传动安装在第一X轴丝杠组件203和第二X轴丝杠组件204导轨上的第一基座205和第二基座206。第一X轴丝杠组件203和第二X轴丝杠组件204包括：固定设置在安装架202上的第一丝杆和第二丝杆（未图示），以及传动连接在第一丝杆和第二丝杆一端的且固定安装在安装架202上的第一伺服电机2010和第二伺服电机2011；第一基座205和第二基座206与第一丝杆和第二丝杆传动连接，进而第一伺服电机2010和第一伺服电机2010的动力经过第一丝杆和第二丝杆传动带动第一基座205和第二基座206在安装架202导轨上滑动；所述第一伺服电机2010和第一伺服电机2010与控制系统电联，并通过控制系统控制该第一基座205和第二基座206之间的间距和移动速度。
所述第一基座205和第二基座206的底部设有第一安装座207和第二安装座208，所述第一安装座207中设有轴承座22有所述轴承座22的一端套接有转轴21，所述轴承座22的另一侧传动连接驱动马达24输出轴；所述转轴21为中空结构；进而驱动马达24的动力带动转轴21在轴承座22中旋转。
所述第二安装座208一端固定安装蒸汽喷嘴250，所述第二安装座208的另一端设有与气管6连通的密封法兰组件29，进而蒸发发生装置在控制系统的开启下通过气管6向蒸汽喷嘴250输送高温高压蒸汽，蒸汽喷嘴250的外部设有电动阀门，可通过控制系统控制蒸汽的大小和流量。
所述清洗组件包括设置在：设置在第二安装座208内部且连通气管6的内腔28，固定连接在转轴21另一端的螺旋形刷体251，以及安装在转轴21内部的电动伸缩结构252；所述内腔28的一端连通蒸汽喷嘴250；所述内腔28的进气口处通过密封法兰组件29与气管6连通，所述电动伸缩结构252伸展的长度可根据圆筒类零件的尺寸进行更换。进而螺旋形刷体251在转轴21随驱动马达24转动的同时带动固定连接在转轴21一端的螺旋形刷体251转动，进而使螺旋形刷体251在零件内壁实现旋转清洁；电动伸缩结构252包括设置在转轴21内部的圆形微动电机2520，安装在微动电机输出端的螺杆2522，以及连接在螺杆2522一端的伸缩管2521，本发明公开图示的为二节式伸缩管2521，¬所述电动伸缩结构252可根据零件的尺寸更换为二节以上；进而可延长螺旋形刷体251在零件中清洁的距离。
所述安装座与第一基座205和第二基座206之间设有铰接座26和角度调整装置；所述角度调整装置为输出端设置在安装座上的液压伸缩杆27，进而液压伸缩杆27带动安装座实现以铰接座26为基点的角度调整。
所述第一X轴丝杠组件203和第二X轴丝杠组件204的上方固定连接多个行程气缸209，所述行程气缸209的动力输出端固定连接第一X轴丝杠组件203和第二X轴丝杠组件204安装架202，进而在多个行程气缸209的带动下带动第一X轴丝杠组件203和第二X轴丝杠组件204同步上下运动。最终实现带动清洁组件上下运动，当清洁组件中的螺旋形刷体251穿插入零件内部时可在行程气缸209的带动下带动零件脱离托盘8，所述托盘8上设有用于防止零件发生滚动的YY形托架80，防止在运输过程中发生偏移而无法与清洁组件对齐；
在进一步的实施例中，所述螺旋形刷体251靠近安装座的一端套接有导流罩7；所述导流罩7的面向油垢收集装置4的一侧开设有导流口70；所述导流罩7的另一端延伸有圆锥形入口71，所述圆锥形入口71可根据零件的尺寸进行更换，所述圆锥形入口71的最大直径大于零件的内口径的直径。当零件随着螺旋形刷体251的角度偏移至导流罩7处，清洁出来的油垢随着导流罩7圆锥形入口71进而导流罩7，进而从导流罩7面向油垢收集装置4的导流口70处流出，进而避免油垢污染传输线3和托盘8。
工作原理如下：将圆筒类零件水平摆放在托盘8上，并且托盘8经过传输线3进入清洗工位；护罩上的X射线检测装置传输过来的零件进行透视检测，对零件内外分布的油垢进出检测评估，控制系统控制传输线3暂停，且同时根据零件的尺寸位置控制第一丝杠组件和第二丝杠组件传动，进而调整第一基座205与第二基座206之间的距离，使得清洁组件之间的间距与零件的长度相等；当护罩上的光栅传感器，检测到圆筒类零件位于两个基座之间时，控制系统控制多个升降气缸同步向下运动，同时调整液压伸缩杆27的伸缩长度进而调整螺旋形刷体251依据蒸汽喷嘴250与圆筒类零件口径对应；控制系统控制蒸汽发生装置5、第一X轴丝杠组件203和第二X轴丝杠组件204伺服电机开启，使得伺服电机带动第一基座205和第二基座206相对运动；同时转轴21中内设电动伸缩结构252伸展，最终实现螺旋形刷体251和蒸汽喷嘴250相互靠近；在蒸汽喷嘴250与螺旋形刷体251同时进入圆筒类零件的内部时调整第一安装座207和第二安装座208上的液压伸缩杆27伸展，从而使圆筒类零件偏向螺旋形刷体251处倾斜，从而使圆筒类零件内部清除下来的油垢顺着螺旋形刷体251流出，掉落至下方的油垢收集装置4中，避免污染托盘8。
本发明通过在龙门架的两侧设有对称的丝杠组件，从而实现该清洗机构2可随着零件的长度进行调整，满足多种型号尺寸圆筒类零件的需要。蒸汽喷嘴250与螺杆2522形刷体相对设置，高温蒸汽向圆筒类零件内部喷射，进而对圆筒类内部积累的油垢或者油泥进行过饱和清洁，溶解的油垢和油泥随着气流向着另一端运动，从而使设置在圆筒类零件的另一端的螺旋形刷体251有序排出，避免油垢的随气流飞溅。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，在本发明的技术构思范围内，可以对本发明的技术方案进行多种等同变换，这些等同变换均属于本发明的保护范围。
