背景技术
光机内设置有光学镜片，光学镜片一般通过插接于光机壳体上的插槽内实现安装固定。
在相关技术中，因为光机壳体通过铸压工艺成型，为了便于光机壳体脱模，插槽的侧壁将倾斜设计而具有一定的拔模斜度。当光学镜片插接于插槽内时，光学镜片的部分表面无法与插槽的侧壁抵接限位，而使光学镜片的安装定位不够可靠，光学镜片容易倾斜而偏离原设计光路的光轴，这将导致光机内部分用于照明和成像的有效光变为无效光，光机将出现相应的亮度及暗带不良，影响光机生产的良品率。

本发明提出一种镜片安装座1，结合图1和图2所示，该镜片安装座1应用于光机，并用于安装固定光学镜片2，镜片安装座1设有通光槽11，通光槽11的相对两侧壁设有朝向通光槽11底壁延伸的插槽12，两个插槽12分别用于限位光学镜片2的相对两端；通光槽11的槽壁设有限位部13，限位部13用于与光学镜片2的部分结构插接配合，以使光学镜片2限位固定于镜片安装座1。
在本实施例中，光学镜片2可有多种结构形态，比如圆形和方形；具体地，结合图3和图5所示，图3所示为圆形光学镜片2，其可包括调光部和环设于调光区外周缘的装配部，调光部可设置为圆形，调光部的入光面和出光面可为弧面，以使调光部成为凸透镜或凹透镜并具有调光作用，而装配部背向调光部的外周面整体呈闭合的圆形环状，装配部可对调光部进行包裹保护，装配部部分插接于插槽12内，并与插槽12抵接限位；图5所示为方形光学镜片2，其同样可包括调光部和环设于调光区外周缘的装配部，调光部可设置为圆形，调光部的入光面和出光面可为弧面，以使调光部成为凸透镜或凹透镜并具有调光作用，而装配部连接于调光部的外周缘，装配部背向调光部的外周面整体呈闭合的方形环状，装配部用于与插槽12插接配合，并部分抵接限位于插槽12内。
限位部13可具有多种结构形态，比如，限位部13可为设置于通光槽11底壁的槽体结构，该槽体结构位于两个插槽12之间，光学镜片2部分插接于该槽体结构内，以此可通过该槽体结构和两个插槽12配合限位固定光学镜片2。再比如，限位部13可为设于通光槽11侧壁并位于设于插槽12上方的槽体结构，光学镜片2部分插接于该槽体结构内，以此可通过该槽体结构和两个插槽12配合限位固定光学镜片2。值得指出的是，上述仅作为限位部13结构的示例性说明，而非对限位部13结构的唯二限定，限位部13完全可设计为能与两个插槽12配合限位固定光学镜片2的其它结构。
每一插槽12具有一定倾斜角度的拔模面，使每一插槽12成为上宽下窄的条形槽，每一插槽12具有远离通光槽11底壁并连通通光槽11槽口的顶槽口，以及背向通光槽11侧壁并连通通光槽11的侧槽口，以使光学镜片2可借由上述顶槽口插入于插槽12内，拔模面邻近于上述顶槽口设置。当光学镜片2插置于插槽12内时，光学镜片2的底端与插槽12的侧壁抵接限位，而 因为插槽12侧壁上拔模面的存在，光学镜片2的顶端与拔模面之间存在一定的间隔空间，从而使光学镜片2的顶端无法被可靠限位，光学镜片2容易产生晃动而倾斜，影响光学镜片2对光路的传播效果。
为解决上述技术问题，本实施例通过独立于插槽12之外的限位部13与光学镜片2的部分结构插接配合，通过限位部13和两个插槽12配合限位固定光学镜片2，有利于提升光学镜片2在镜片安装座1上安装固定的可靠性。此外，仅通过设置限位部13实现光学镜片2在镜片安装座1上的安装固定，使本镜片安装座1的结构相对简单，镜片安装座1的改进成本低，镜片安装座1易于复制和反复生产，能够在提升本镜片安装座1和采用本镜片安装座1的光机的良品率同时，兼顾降低本镜片安装座1和采用本镜片安装座1的光机的制造成本。
上述光学镜片2至少包括圆形光学镜片2和方形光学镜片2两种，在光学镜片2的形状不同时，可将限位凸部13设计为不同结构形态，以实现光学镜片的更可靠的限位固定，以下对不同形状的光学镜片2在本镜片安装座上的固定实现进行说明：
实施例一：
当光学镜2片为圆形时，结合图3和图4所示，限位部13包括第一限位槽131，第一限位槽131设于通光槽的底壁，第一限位槽131与两个插槽12配合限位固定光学镜片2。
在本实施例中，通过将限位部13设计为第一限位槽131，使本镜片安装座1无需增加额外安装结构即可实现光学镜片2的安装，有利于降低本镜片安装座1的物料成本。同时因为槽体结构易于加工形成，且第一限位槽131可与镜片安装座1通过压铸工艺一体成型，利于缩减镜片安装座1的加工程序，降低本镜片安装座1的加工成本。此外，通过将第一限位槽131设置于通光槽11的底壁，使光学镜片2的裙边的底端通过插接于第一限位槽131内进行限位，光学镜片2的裙边的侧端插置于插槽12内，通过插槽12进行限位，从而使光学镜片2的裙边部位被限位固定，如此光学镜片2不会前后或左右晃动，提升了光学镜片2在镜片安装座1上安装固定的可靠性。
可选地，结合图3和图4所示，实施例一中的第一限位槽131的底壁设有第一载块14；第一载块14背向第一限位槽131底壁的一侧设有第一限位面141，第一限位面141用于抵接限位光学镜片2。
在本实施例中，第一载块14可为弹性材质，比如硅胶、海绵等，以使光学镜片2的部分结构在限位于第一限位槽131内时，光学镜片2的裙边底端与第一载块14弹性抵接，而防止光学镜片2与第一限位槽131的底壁直接接触，造成光学镜片2磨损或划伤。第一载块14也可以具有固定高度或厚度的硬质材质，以使第一载块14可作为调节光学镜片2光轴高度的垫块，通过改变第一载块14的高度可对应改变光学镜片2的光轴的高度，从而依据光路设计对光学镜片2的高度位置进行调节，保证光学镜片2与光路的准确契合。
第一限位面141可为弧面，以使圆形光学镜片2的弧形边缘可限位于第一限位槽131内，并与第一限位面141承靠抵接，使第一载块14借助第一限位面141对光学镜片2进行可靠支撑和限位，提升第一载块14与光学镜片2配合的紧密性和可靠性。
可选地，如图2所示，实施例一中的每一插槽12的底壁设有第二载块16；第二载块16背向插槽12底壁的一侧设有第二限位面161，第二限位面161用于抵接限位光学镜片2。
在本实施例中，第二载块16可为弹性材质，比如硅胶、海绵等，以使光学镜片2的部分结构在限位于插槽12内时，光学镜片2的侧边缘可与第二载块16弹性抵接，而防止光学镜片2与插槽12的底壁直接接触，造成光学镜片2磨损或划伤。第二载块16背向插槽12底壁的一侧可呈弧面设置，以使光学镜片2的弧形边缘可与第二载块16的弧面承靠抵接，实现光学镜片2的可靠固定。第二载块16也可以具有固定厚度的硬质材质，以使第二载块16可作为调节光学镜片2光轴高度的垫块，通过改变第二载块16的厚度可对应改变光学镜片2的光轴的位置，从而依据光路设计对光学镜片2的位置进行调节，保证光学镜片2与光路的准确契合。
实施例二：
当光学镜片2为方形时，结合图5和图6所示，限位部13包括第二限位 槽132，第二限位槽132位于两个插槽12背向通光槽11底壁的一侧，并与两个插槽12连通；第二限位槽132、两个插槽12与通光槽11的底壁配合限位固定光学镜片。
在本实施例中，结合图2和图4所示，通光槽11相对的两个侧壁分别设有一个第二限位槽132；每一个第二限位槽132位于一插槽12背向通光槽11底壁的一侧，并与一插槽12连通。以此，整个第二限位槽132位于两个插槽12上方，并与两个插槽12连通，光学镜片2侧边的顶端限位于第二限位槽132内，光学镜片2侧边的底端限位于插槽12内，如此第二限位槽132和两个插槽12配合限位固定光学镜片2，防止光学镜片2在光路上的偏摆，提升光学镜片2在镜片安装座上安装固定的可靠性。
可选地，结合图5和图6所示，实施例二中的第二限位槽132与每一插槽12的连通处形成有限位台阶15，限位台阶15用于限位固定光学镜片2。
在本实施例中，第二限位槽132与插槽12的连通处形成有可限位光学镜片2的限位台阶15，光学镜片2可对应于每一限位台阶15设置有一限位凸部21，当光学镜片2插置于两个插槽12内时，光学镜片2的两个限位凸部21分别至少部分容纳并限位于两个第二限位槽132内，两个限位凸部21分别与两个限位台阶15抵接限位。以此，光学镜片2靠近通光槽11底壁的一端与插槽12侧壁邻近底壁的部位抵接限位，光学镜片2的远离通光槽11底壁的一端通过限位凸部21与限位台阶15抵接限位，从而能够保证光学镜片2在镜片安装座1上的可靠固定而不易松动或倾斜，保证光学镜片2与光路准确契合。
可选地，结合图2、图5以及图6所示，实施例二中的限位部13还包括第一限位槽131；第一限位槽131与两个插槽12连通，第二限位槽132位于两个插槽12背向通光槽11底壁的一侧，并与两个插槽12连通；第一限位槽131、第二限位槽132与两个插槽12配合限位固定光学镜片。
在本实施例中，同时设置第一限位槽131和第二限位槽132，光学镜片2的底边插接于第一限位槽131内，光学镜片2的侧边的顶端插接于第二限位槽132内，光学镜片2侧边的底端插接于插槽12内，如此通过第一限位槽131 可限位固定光学镜片2的底边，通过第二限位槽132和两个插槽12可限位固定光学镜片2的侧边，通过第一限位槽131、第二限位槽132与两个插槽12的配合可实现整个光学镜片的安装固定。其中，第一限位槽131的底壁可设有第一载块14；第一载块14背向第一限位槽131底壁的一侧设有第一限位面141，第一限位面141用于抵接限位光学镜片2，通过改变第一载块14的高度可对应改变方形光学镜片2的光轴的高度，从而依据光路设计对方形光学镜片2的高度位置进行调节，保证光学镜片2与光路的准确契合。第一限位面141可为平面，以使方形光学镜片2的底边可承靠抵接于第一限位面141，使第一载块14借助第一限位面141对方形光学镜片2进行可靠的支撑和限位，提升第一载块14与方形光学镜片2配合的紧密性和可靠性。
可选地，如图2所示，实施例二中的每一插槽12的底壁设有第二载块16；第二载块16背向插槽12底壁的一侧设有第二限位面161，第二限位面161用于抵接限位光学镜片2。
在本实施例中，第二载块16可为弹性材质，比如硅胶、海绵等，以使光学镜片2的部分结构在限位于插槽12内时，光学镜片2的侧边缘可与第二载块16弹性抵接，而防止光学镜片2与插槽12的底壁直接接触，造成光学镜片2磨损或划伤。第二载块16也可以具有固定厚度的硬质材质，以使第二载块16可作为调节光学镜片2光轴高度的垫块，通过改变第二载块16的厚度可对应改变光学镜片2的光轴的位置，从而依据光路设计对光学镜片2的位置进行调节，保证光学镜片2与光路的准确契合。
实施例三：
当镜片安装座上需安装固定多个光学镜片2时，如图1所示，通光槽11的侧壁设有多个插槽12，多个插槽12分别设于通光槽11的相对两侧壁；通光槽11的槽壁设有多个限位部13，一限位部13与分别位于通光槽11相对两侧壁的两个插槽12配合限位固定一光学镜片2。
在本实施中，镜片安装座1可同时装配多个光学镜片2，镜片安装座1上的通光槽11可为直线延伸的槽体结构，也可以为具有直段和折弯段的槽体结构。当镜片安装座1设有多个插槽12时，多个插槽12两两对称设置于通光 槽11的相对两侧壁，每一光学镜片2插接于通光槽11相对两侧壁上对应设置两个插槽12内，多个光学镜片2可保持同轴设置，也可以依据实际光路传播需要，将多个光学镜片2按照特定的位置和角度设置，此处不做限定。通过在镜片安装座1上设置多个光学镜片2，有利于提升光学镜片2之间的排列的紧凑性，从而有利于缩减采用本镜片安装座1的光路结构的空间占用。为实现圆形光学镜片2在镜片安装座上的安装固定，限位部13可采用上述实施例一中的第一限位槽131的结构形态；为实现方形光学镜片2在镜片安装座上的安装固定，限位部13可采用上述实施例二中的第二限位槽132或第一限位槽131与第二限位槽132相结合的结构形态，其中第一限位槽131和第二限位槽132的具体结构参见上述实施例，由于本实施例可采用上述实施例中相应的技术方案实施，因此也就具有被采用的技术方案所带来的有益效果，在此不再一一赘述。
此外，本发明还提出一种光机，如图1所示，该光机包括光学镜片2和上述各实施例中的镜片安装座1，光学镜片2的相对两端分别限位于镜片安装座1的两个插槽12内，光学镜片2与镜片安装座1的限位部13插接配合，以使光学镜片2限位固定于镜片安装座1。
在本实施例中，光机为光电精密仪器，其可用于激光加工，光机可包括机壳，机壳具有可容置和安装镜片安装座1的腔体结构。光学镜片2可配合光机内的激光发射器实现相应的激光加工流程。光学镜片2用于调节光机内的光路，从而改变光机的输出光路，实现相应的激光聚焦和加工效果。
限位部13可具有多种结构形态，比如，限位部13可为设置于通光槽11底壁的槽体结构，该槽体结构位于两个插槽12之间，光学镜片2部分插接于该槽体结构内，以此可通过该槽体结构和两个插槽12配合限位固定光学镜片2。再比如，限位部13可为设于通光槽11侧壁并位于设于插槽12上方的槽体结构，光学镜片2部分插接于该槽体结构内，以此可通过该槽体结构和两个插槽12配合限位固定光学镜片2。值得指出的是，上述仅作为限位部13结构的示例性说明，而非对限位部13结构的唯二限定，限位部13完全可设计为能与两个插槽12配合限位固定光学镜片2的其它结构。
本实施例中的镜片安装座1的具体结构参照上述实施例，由于本光机采 用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
在本发明的一实施例中，结合图2、图4以及图5所示，光学镜片2包括圆形光学镜2片和方形光学镜片2；方形光学镜片2远离镜片安装座的通光槽11底壁的一端设有两个限位凸部21；两个限位凸部21分别限位于两个第二限位槽132内，每一限位凸部21与一限位台阶15抵接限位。
在本实施例中，在通光槽11的侧壁设有第二限位槽132，第二限位槽132位于两个插槽1上方，并与两个插槽12连通，第二限位槽132与插槽12的连通处形成有可限位光学镜片2的限位台阶15，方形光学镜片2对应于每一限位台阶15设置有一限位凸部21，当方形光学镜片2插置于两个插槽12内时，方形光学镜片2的两个限位凸部21分别至少部分容纳并限位于两个第二限位槽132内，两个限位凸部21分别与两个限位台阶15抵接限位。以此，方形光学镜片2的侧边的顶端插接于第二限位槽132内，光学镜片2侧边的底端插接于插槽12内，通过第二限位槽132和两个插槽12的配合可限位固定方形光学镜片2，从而能够保证方形光学镜片2在镜片安装座1上的可靠固定而不易松动或倾斜，保证方形光学镜片2与光路准确契合。
在通光槽11的底壁还设置有第一限位槽131，圆形光学镜片2的裙边的底端可插接于第一限位槽131内，圆形光学镜片2裙边的侧端可插接于两个插槽12内，如此通过一第一限位槽131和两个插槽12配合可限位固定圆形光学镜片2，保证圆形光学镜片2在镜片安装座1上的可靠固定而不易松动或倾斜，保证圆形光学镜片2与光路准确契合。
