Description

一种导轨侧面滚动涂油装置
技术领域
本发明涉及导轨生产领域，特别是涉及一种导轨侧面滚动涂油装置。
背景技术
T型钢导轨在电梯中的应用比较方法，由于电梯运行精度和稳定性受T型钢导轨的影响较大，因此对T型钢导轨的加工精度要求较高。
T型钢导轨的两侧精度要求高，需要进行刨床加工，而且加工完成后需要涂油进行防锈处理，避免生锈而影响使用。目前导轨侧面的涂油主要通过人工涂油和机械涂油，人工涂油的效率低，防锈油浪费严重，而机械涂油难以涂抹均匀，实用性差。
发明内容
本发明主要解决的技术问题是提供一种导轨侧面滚动涂油装置，提升导轨侧面涂油的工作效率和涂油均匀性。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种导轨侧面滚动涂油装置，包括：支撑架和两块支撑板，所述两块支撑板分别设置在支撑架的顶部和底部并向外侧延伸，所述支撑板的末端分别设置有轴承，两个轴承之间设置有向上延伸的中心转轴，所述中心转轴内设置有储油腔，所述中心转轴的外侧同心设置有支撑套筒，所述支撑套筒的外侧同心设置有涂油面层，所述中心转轴与支撑套筒内壁的上部之间设置有数个导油管相连接。
在本发明一个较佳实施例中，所述中心转轴的顶部设置有与储油腔相连接的万向油枪嘴。
在本发明一个较佳实施例中，所述涂油面层为橡胶套、海绵套、多层无纺布或者多层织物面料。
在本发明一个较佳实施例中，所述橡胶套上密布有微孔。
在本发明一个较佳实施例中，所述数个导油管环形阵列设置在所述中心转轴的外圆上。
在本发明一个较佳实施例中，所述导油管与储油腔相连通。
在本发明一个较佳实施例中，所述支撑套筒内壁上设置有与导油管相连通的通孔。
在本发明一个较佳实施例中，所述支撑架的外侧设置有牵引板。
在本发明一个较佳实施例中，所述导轨侧面滚动涂油装置还包括固定座和伸缩驱动装置，所述固定座上设置有位于支撑架下方的滑轨，所述伸缩驱动装置设置在固定座上且与牵引板相连接，所述伸缩驱动装置为油缸或者气缸。
在本发明一个较佳实施例中，所述支撑套筒的顶部设置有与中心转轴相连接的第一环形挡板，所述支撑套筒的底部设置有与中心转轴相连接的第二环形挡板。
本发明的有益效果是：本发明指出的一种导轨侧面滚动涂油装置，利用伸缩驱动装置的伸长而把支撑架推向导轨的侧面，利用导轨的输送摩擦而带动涂油面层的旋转，同时，外部的防锈油通过万向油枪嘴注入储油腔，并通过导油管进入涂油面层，对涂油面层进行浸油处理，使得涂油面层旋转的同时把防锈油涂抹在导轨的侧面，涂油均匀性好，自动化程度高，涂油量通过万向油枪嘴得以控制，节油性好，调节方便，工作效率高。
