具体实施方式
为了更好地理解和实施，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
在本发明的描述中，需要说明的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在限制本发明。
请参照图1至图7，一种抛光磨头驱动装置，包括主轴6，用于连接抛光磨头1；轴承座5，套设于主轴6外并与该主轴6转动连接；以及直驱电机，其定子7固定连接至轴承座5，转子8套设于主轴6外并与主轴6传动连接。本实施例中，通过使用直驱电机驱动主轴6，大大减小了抛光磨头驱动装置的体积以及重量，简化了抛光磨头驱动装置的整体结构，装配简单易于维护，降低装置故障率的同时保障了生产效率。
进一步地，如图1和图3所示，转子8与主轴6之间配置有旋转轴套4，该旋转轴套4套设于主轴6外并与主轴6传动连接；转子8与旋转轴套4传动连接；主轴6能够沿旋转轴套4的轴向相对于旋转轴套4滑动。具体地，转子8与旋转轴套4之间通过平键9传动连接。这里的旋转轴套4通过第一轴承2与轴承座5转动连接。旋转轴套4的内壁固定嵌套有衬筒23，主轴6嵌设于衬筒23内，衬筒23内壁沿衬筒23轴向开设有导向槽2301，这里的主轴6轴向与衬筒23轴向平行。进一步地，主轴6上配置有与导向槽2301适配的导向块10；当旋转轴套4套设于主轴6外时，导向块10滑动嵌设于导向槽2301内。
本实施例中，导向槽2301为长方体状。导向槽2301的两端延伸至衬筒23的端面，并且导向块10的长度大于导向槽2301的长度(衬筒23的长度)。衬筒23与旋转轴套4通过螺栓或者螺钉可拆卸连接，方便拆卸更换，同时衬筒23与旋转轴套4的组合结构，方便在两者上各自加工与平键9配合的键槽以及与导向块10配合的导向槽2301。由于导向块10与导向槽2301为滑动配合，因此在使用一定时间后，导向槽2301被磨损会导致传动装配精度下降，而通过定期更换衬筒23的方式便可避免此问题，同时衬筒23体积小，加工成本低，相较于直接更换旋转轴套4可有效减小生产成本。
当然，在其他实施例中，也可将衬筒23与旋转轴套4一体成型，即直接在旋转轴套4内壁上开设导向槽2301。
本实施例中，导向块10与主轴6通过螺栓或者螺钉可拆卸连接，当导向块10受损后便于更换。在其他实施例中，导向块10也可与主轴6焊接。
如图1和图7所示，抛光磨头驱动装置还包括驱动件12，用于驱动主轴6以使得该主轴6能够相对于旋转轴套4滑动。本实施例中，驱动件12为气缸。如图2所示，在安装抛光磨头1并将抛光磨头驱动装置固定在抛光机机架上后，驱动件12与直驱电机的定子7之间的位置相对固定。进一步地，主轴6外套设有连接轴套13，连接轴套13与主轴6通过第二轴承22转动连接；为了保证连接轴套13与主轴6的同轴度，连接轴套13与主轴6之间安装有两个第二轴承22，两个轴承之间通过套筒20限位。
更进一步地，如图5和图6所示，主轴6外套设有连接轴套13，连接轴套13与主轴6转动连接；连接轴套13的上端配置有下密封盘15，主轴6外套设有上密封盘16；上密封盘16能够跟随主轴6转动；下密封盘15包括第一本体1501，第一本体1501上贯穿设置有第一通孔1502，第一本体1501的上表面配置有至少两个下滑环1503；上密封盘16包括第二本体1601，第二本体1601上贯穿设置有第二通孔1602，第二本体1601的下表面配置有至少两个上滑环 1603；主轴6贯穿第一通孔1502和第二通孔1602，当下密封盘15和上密封盘16装配后，下滑环1503和上滑环1603交错分布；驱动件12的驱动端固定连接至连接轴套13或者下密封盘15。
本实施例中，于主轴6的上端螺纹安装有限位螺母21，该限位螺母21处于上密封盘16的上侧，通过旋紧限位螺母21对上密封盘16限位，以防止其从主轴6上端脱落。优选的，于限位螺母21和上密封盘16之间配置有橡胶垫片，防止限位螺母21将上密封盘16压伤。
在使用时，主轴6同时穿过第一通孔1502和第二通孔1602，第一通孔1502和第二通孔1602同轴。上滑环1603和下滑环1503均可以是一一对应的两个或者多个，上滑环1603和下滑环1503彼此间隔嵌套，相邻两个上滑环1603之间构成上密封槽，相邻两个下滑环1503之间构成下密封槽，通过上滑环1603和下滑环1503彼此间隔嵌套的装配结构使得外界的杂质不易通过上滑环1603和下滑环1503之间的间隙进入第二轴承22处。
本实施例中，上滑环1603抵接至第二轴承22的内圈，下滑环1503抵接至第二轴承22的外圈。第二轴承22的外圈与连接轴套13的内壁紧配合。
本实施例中，如图1和图2所示，进一步地，下密封盘15上通过螺栓或者螺钉固定安装有支板17，支板17上方通过螺钉或者螺栓固定安装有盖板18，用于对上密封盘16和下密封盘15的连接结构进行封闭保护。本实施例中，为了方便安装，驱动件12的驱动端固定连接至支板17。由于盖板18、支板17、下密封盘15和连接轴套13之间的纵向位置相对固定，即四者固定连接，因此在其他实施例中，驱动件12的驱动端可固定连接至四者任一上。
本实施例中，在使用时，直驱电机通电，转子8转动并通过平键9驱动旋转轴套4同步转动，旋转轴套4通过衬筒23上的导向槽2301与主轴6上的导向块10配合从而驱动主轴6同步转动，从而实现对安装在主轴6上的抛光磨头1的驱动；同时，当需要提升抛光磨头1使其远离被打磨陶瓷或者下压抛光 磨头1使其靠近被打磨陶瓷时，启动驱动件12，其驱动端驱动支板17，通过下密封盘15、连接轴套13以及第二轴承22将驱动力传递给主轴6以实现抛光磨头1的纵向位置调节。当提升抛光磨头1使其远离被打磨陶瓷时，驱动件12伸长，，过程中，导向块10在导向槽2301内向上滑动，从而可在不影响主轴6转动的前提下将其提升，进而使得抛光磨头1向上远离被打磨陶瓷；相对地，当下压抛光磨头1使其靠近被打磨陶瓷时，驱动件12缩短，主轴6以及抛光磨头1在自身重力作用下，以及在驱动件12的作用下，使得主轴6受到沿其轴向向下的作用力，过程中，导向块10在导向槽2301内向下滑动，从而可在不影响主轴6转动的前提下将其下压，进而使得抛光磨头1向下靠近被打磨陶瓷。
本实施例中，导向块10和导向槽2301的配合结构一方面起到了滑动导向的作用，另一方面起到了键传动的作用。
本实施例中，为了在抛光磨头1工作过程提供冷却液，如图1和图2所示，主轴6内沿其轴向贯穿设置有冷却通道601。该冷却通道601连通至抛光磨头1。进一步的，冷却通道601内转动嵌套有导管14，导管14固定连接至连接轴套13或者下密封盘15；导管14用于外接冷却设备。这里的导管14自主轴6上端嵌入冷却通道601，其上端穿过盖板18，导管14与冷却通道601内壁之间通过密封圈24密封。导管14上端螺纹连接有锁筒19，锁筒19侧壁开设有进口1901，外接的冷却设备将冷却液自进口1901导入导管14，冷却液通过导管14进入冷却通道601最终到达抛光磨头1。这里的密封圈24可防止冷却液从冷却通道601的上端溢出。在实际使用时，当密封圈24失效时，会有冷却液从冷却通道601的上端溢出，此时上密封盘16和下密封盘15的装配结构即可防止溢出的冷却液侵蚀第二轴承22。
如图6所示，于下密封盘15的上表面开设有泄水槽1504，泄水槽1504设置于下密封盘15周向外侧且与下密封槽连通。在使用时，上密封盘16跟随 主轴6转动，当有冷却液自冷却通道601的上端溢出时，冷却液在上密封盘16转动的离心力作用下流入下密封盘15并通过泄水槽1504溢流。
本实施例中，如图1和图4所示，旋转轴套4与主轴6之间配置有衬套3，衬套3滑动套设于主轴6外，衬套3与旋转轴套4固定连接。这里的衬套3用于在下端扶正主轴6，防止其在径向侧倾，保证抛光磨头驱动装置的精度，起到滑动轴承的作用。这里的衬套3与旋转轴套4通过螺栓或者螺钉可拆卸连接，当使用过程中衬套3出现受损影响到精度时，可对其拆换，相较于直接更换旋转轴套4的方式节约了生产成本。
如图1和图3所示，旋转轴套4的上端配置有保护轴套11，该保护轴套11套设于主轴6外，保护轴套11的上端自连接轴套13的下端延伸至连接轴套13内，与连接轴套13共同对主轴6形成遮挡，防止杂质进入导向块10和导向槽2301之间的间隙。
本实施例还提供了一种抛光机，包括抛光磨头1和上述的抛光磨头驱动装置，抛光磨头驱动装置用于安装并驱动抛光磨头1。抛光磨头驱动装置的定子7以及驱动件12均固定安装至抛光机的结构件(机架)上。这里的抛光磨头驱动装置结构简单且体积小，使得抛光机在工作过程中更加节能。
本发明方案所公开的技术手段不仅限于上述实施方式所公开的技术手段，还包括由以上技术特征任意组合所组成的技术方案。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
