背景技术
随着经济和社会的发展，提高工作效率、产品质量已成为发展的必然趋势。各种工具也越来越朝向使用方便、安全高效的方向发展，研磨抛光机作为美容的重要工序也不例外。
一般的，研磨抛光机为提高研磨效果，采用能调节旋转曲率的辅助机构与抛光轮连接，辅助机构通过调节轴套与分度盘的相对位置，达到调节抛光轮曲率半径的目的，在需要调节时，轴套需能相对分度盘转动，不需要调节时，轴套需与分度盘联动，所以需要设计一个机构能对轴套与分度盘的这两种状态进行高效地切换。
发明内容
基于此，本发明在于克服现有技术的缺陷，提供一种抛光机及其旋转定位机构，不仅能高效对轴套与分度盘的相对状态进行切换，且使用方便。
一种抛光机的旋转定位机构，包括定位珠、固定座、弹性件及调整销，所述固定座用于固定在抛光机的轴套上，且固定座的一侧靠近抛光机的分度盘，所述固定座靠近轴套的端面挖设有安装槽，且所述安装槽的底壁上设有贯穿至固定座顶端的第一通孔，所述安装槽靠近分度盘的侧壁上设有第二通孔，所述调整销设置在所述安装槽内，且调整销的顶端伸出所述第一通孔，所述弹性件位于所述轴套与调整销之间，当按压所述调整销时，所述定位珠由第二通孔进入所述安装槽内，当松开所述调整销时，所述定位珠部分卡设在所述分度盘的定位孔内。
其进一步技术方案如下：
所述调整销包括依次连接的第一销段、第二销段及第三销段，所述第一销段部分伸出所述第一通孔，所述第三销段压在所述弹性件上，所述第二销段的直径由第一销段向第三销段逐渐增大。
所述第三销段的端面上设有定位槽，所述弹性件伸入所述定位槽内且抵接在定位槽的底壁上。
所述弹性件为伸缩弹簧。
所述轴套与固定座接触的外壁为平面，该平面上设有与调整销底端匹配的嵌槽，所述嵌槽的底壁上设有与弹性件匹配的盲孔。
所述固定座的两侧设有凸块，所述凸块上设有通孔，紧固件穿过所述通孔将所述固定座固定在所述轴套上。
所述分度盘上设有多个定位孔，所述定位孔沿轴套的周向布置且与所述定位珠对应设置。
一种抛光机，包括分度盘、轴套、偏心机构及所述抛光机的旋转定位机构，所述轴套的一端设有转轴，另一端设有第一轴孔，所述第一轴孔的中心与所述转轴的中心不同轴，所述转轴与分度盘可转动连接，所述偏心机构的一端设有限位柱，另一端用于与抛光轮连接，所述轴套靠近分度盘的端面上设有弧形孔，所述分度盘上设有调节孔，所述偏心机构设置在所述第一轴孔内，且所述限位柱依次穿设于所述弧形孔及调节孔内，所述轴套通过所述抛光机的旋转定位机构限位在所述分度盘上。
所述偏心机构包括偏心调整片、偏心套、弹簧、离合调整块及连接轴，所述偏心调整片上设有穿孔，所述限位柱设置在所述偏心套上，所述离合调整块与所述连接轴的第一端固定连接，所述偏心套套在所述离合调整块上，所述限位柱依次穿设于所述穿孔、弧形孔及调节孔内，所述弹簧一端抵在所述轴套上，另一端抵在所述偏心调整片上，使偏心调整片压紧在所述离合调整块上，当所述离合调整块受到的阻力大于额定阻力时，离合调整块相对偏心调整片转动。
所述的抛光机还包括过渡连接头及第一卡簧，所述分度盘上设有连接孔，所述转轴穿过所述连接孔与所述过渡连接头一端连接，过渡连接头的另一端用 于与驱动机构连接，所述转轴靠近过渡连接头的一端外壁设有第一环形槽，所述第一卡簧设置在所述第一环形槽内，且第一卡簧挡在所述分度盘外。
下面对前述技术方案的优点或原理进行说明：
上述抛光机及其旋转定位机构，当需要调整抛光轮的旋转曲率半径时，按压调整销顶端，由于调整销与轴套外壁之间设置有弹性件，按压过程中弹性件被压缩，调整销沿其轴向方向移动改变其与定位柱的接触部位，从而在安装槽内让位出空间使定位柱进入，解除轴套与分度盘之间的连接限制，使轴套能相对分度盘转动，当轴套旋转到位后，松开调整销，调整销在弹性件的作用下自动回位，回位过程中同步推挤定位珠，使定位珠的一部分进入当前位置的定位孔内，使轴套被定位柱卡在分度盘上，使轴套不能相对分度盘转动，锁定与松开状态能方便快捷操作，效率高。

为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施方式。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本发明的公开内容理解的更加透彻全面。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。相反，当元件被称作“直接在”另一元件“上”时，不存在中间元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
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方式的目的，不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1-3所示，一种抛光机的旋转定位机构，包括定位珠410、固定座420、弹性件430及调整销440，所述固定座420用于固定在抛光机的轴套20上，且固定座420的一侧靠近抛光机的分度盘10，所述固定座420靠近轴套20的端面挖设有安装槽422，且所述安装槽422的底壁上设有贯穿至固定座顶端的第一通孔424，所述安装槽靠近分度盘的侧壁上设有第二通孔426，所述调整销440设置在所述安装槽422内，且调整销440的顶端伸出所述第一通孔424，所述弹性件430位于所述轴套20与调整销440之间，当按压所述调整销440时，所述定位珠410由第二通孔426进入所述安装槽内，当松开所述调整销440时，所述定位珠410部分卡设在所述分度盘10的定位孔120内。
当需要调整抛光轮的旋转曲率半径时，按压调整销440顶端，由于调整销440与轴套20外壁之间设置有弹性件430，按压过程中弹性件430被压缩，调整销440沿其轴向方向移动改变其与定位柱的接触部位，从而在安装槽422内让位出空间使定位柱进入，解除轴套20与分度盘10之间的连接限制，使轴套20能相对分度盘10转动，当轴套20旋转到位后，松开调整销440，调整销440 在弹性件430的作用下自动回位，回位过程中同步推挤定位珠410，使定位珠410的一部分进入当前位置的定位孔120内，使轴套20被定位柱卡在分度盘10上，使轴套20不能相对分度盘10转动，锁定与松开状态能方便快捷操作，效率高。
如图2所示，本实施例所述调整销440包括依次连接的第一销段442、第二销段444及第三销段446，所述第一销段442伸出所述第一通孔424，所述第三销段446压在所述弹性件430上，所述第二销段444的直径由第一销段442向第三销段446逐渐增大。第二销段444为顶端大底端小的锥状，不按压第一销段442时，第二销段444的大端抵着定位珠410使其被推进定位孔120内，按压第一销段442，第二销段444下移，逐渐让出容纳空间，定位珠410从定位孔120中脱出进入容纳槽325内。根据需求，调整销440也可采用在中部设置一个圆弧过渡的凸包结构，通过凸包抵压定位珠410。
所述第三销段446的端面上设有定位槽441，所述弹性件430伸入所述定位槽441内且抵接在定位槽441的底壁上。通过设置定位槽441，使弹性件430被限位在槽内且同时对弹性件430进行导向。
如图1、2所示，所述轴套20与固定座420接触的外壁为平面，该平面上设有与调整销440底端匹配的嵌槽240，所述嵌槽240的底壁上设有与弹性件匹配的盲孔，通过设置嵌槽240，当调整销440朝轴套20移动时，起到让位的作用，设置盲孔对弹性件430进行定位。所述弹性件为伸缩弹簧，也可以是其他具有弹性功能的零件，如弹性柱等等。
如图1、3所示，所述固定座420的两侧设有凸块428，所述凸块428上设有通孔，紧固件穿过所述通孔将所述固定座420固定在所述轴套20上。所述紧固件为螺钉或者螺母等。
如图1所示，所述分度盘上设有多个定位孔120，所述定位孔120沿轴套20的周向布置且与所述定位珠410对应设置。不同位置的定位孔120，对应抛光轮不同的旋转曲率半径，按压调整销440，带动定位珠410旋转直到其与对应曲率半径的定位孔120对正，松开调整销440，定位珠410进入该定位孔120使 轴套20与分度盘10连接。
如图1、2、4所示，一种抛光机，包括分度盘10、轴套20、偏心机构30及所述抛光机的旋转定位机构，所述轴套20的一端设有转轴210，另一端设有第一轴孔220，所述第一轴孔220的中心与所述转轴210的中心不同轴，所述转轴210与分度盘10可转动连接，所述偏心机构30的一端设有限位柱310，另一端用于与抛光轮连接，所述轴套20靠近分度盘10的端面上设有弧形孔，所述分度盘10上设有调节孔110，所述偏心机构30设置在所述第一轴孔220内，且所述限位柱310依次穿设于所述弧形孔及调节孔110内，所述轴套20通过所述抛光机的旋转定位机构限位在所述分度盘10上。
驱动机构带动转轴210及轴套20转动，由于偏心机构30位于第一轴孔220内，第一轴孔220与转轴210不同心，且偏心机构30通过限位柱310限位在分度盘10的调节孔110内，而分度盘10通过定位珠410与轴套20连接，所以分度盘10及偏心机构30随之转动，从而能带动与偏心机构30连接的抛光轮作偏心旋转运动，当需要调整抛光轮的旋转曲率半径时，松开调整销440使轴套20相对分度盘10转动，偏心机构30随限位柱310只能在分度盘10的调节孔110内移动，使偏心机构30与转轴210之间的偏心距发生改变，从而达到调整抛光轮的旋转曲率半径的目的，进而改变抛光轮的运行轨迹，从而达到不同的抛光效果。
如图4所示，本实施例所述偏心机构30包括偏心调整片320、偏心套330、弹簧340、离合调整块350及连接轴360，所述偏心调整片320上设有穿孔321，所述限位柱310设置在所述偏心套330上，所述离合调整块350与所述连接轴360的第一端固定连接，所述偏心套330套在所述离合调整块350上，所述限位柱310依次穿设于所述穿孔321、弧形孔及调节孔110内，所述弹簧340一端抵在所述轴套20上，另一端抵在所述偏心调整片320上，使偏心调整片320压紧在所述离合调整块350上，当所述离合调整块350受到的阻力大于额定阻力时，离合调整块350相对偏心调整片320转动。偏心调整片320通过弹簧340压紧在离合调整块350上形成离合结构，弹簧340做过度调节，能适应更复杂的曲 面工作，当抛光轮在抛光、研磨过程中遇到大的阻力时，离合调整块350打滑，使离合调整块350相对偏心调整片320转动，避免抛光轮上的力过大从而使抛光面出现深的抛光伤痕。当然，为节省成本，根据实际需求偏心机构30也可以不设置离合结构，直接采用偏心调整片320与连接轴360连接，连接轴360的轴心线与偏心调整片320的中心线不同轴。
所述弹簧340为锥形弹簧，该锥形弹簧的大端靠近所述偏心调整片320，且锥形弹簧大端的末端卡设于所述固定孔内，能对弹簧340进行限位，同时设置锥形弹簧，使弹簧340在压缩状态下的厚度尽可能薄，有效节省第一轴孔220的内部空间高度，使整个机构更紧凑，性能更稳定。
如图2、4所示。所述的抛光机还包括过渡连接头60及第一卡簧70，所述分度盘10上设有连接孔，所述转轴210穿过所述连接孔与所述过渡连接头60一端连接，过渡连接头60的另一端用于与驱动机构连接，所述转轴210靠近过渡连接头60的一端外壁设有第一环形槽，所述第一卡簧70设置在所述第一环形槽内，且第一卡簧70挡在所述分度盘10外。所述过渡连接头60为两端带螺纹中间带六角盘的结构，一端用于与转轴210螺纹连接，另一端用于与驱动机构连接，通过第一卡簧70限制分度盘10的轴向移动，使分度盘10与轴套20贴紧只能相对转动。
进一步，所述偏心机构30还包括轴承370，所述轴承370套设在所述连接轴360上，所述连接轴360上设有第三卡簧380，且第三卡簧380位于轴承370与离合调整块350之间，所述偏心套330设置所述轴承370及离合调整块350上。通过设置轴承370，使所述离合调整块350及连接轴360相对偏心调整片320、偏心套330转动时更顺畅，且设置第三卡簧380于轴承370与离合调整块350之间，限制离合调整块350及轴承370的轴向自由度，使两者转动过程互不干涉。
如图2、4所示，所述偏心套330内远离偏心调整片320的一端设有轴封332，所述连接轴360穿过所述轴封332伸出所述偏心套330，且所述连接轴360远离偏心调整片320的端面上设有螺纹孔。通过设置轴封332对偏心套330内部进 行保护，避免灰尘等进行内部零件，本实施例中所述螺纹孔为内螺纹孔，用于连接抛光轮。
所述第一轴孔220内远离转轴210的一端设有第二环形槽，所述第二环形槽内设有第二卡簧50，且第二卡簧50挡在所述偏心套330外将所述偏心套330限位在所述第一轴孔220内。通过第二卡簧50将偏心机构30限位在轴套20内，使偏心机构30与轴套20之间能发生相对转动而不能轴向移动。
进一步，如图1、4所示，所述分度盘10上还设有用于使抛光机保持旋转平衡的第一配重块80及第二配重块90。为避免整体机构旋转不稳，通过增加第一配重块80及第二配重块90调整机构重心，使机构旋转过程保持平衡。第一配重块80及第二配重块90的设置位置与偏心机构30的重心相关。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
