Description

一种调平装置及三维打印设备 技术领域
本实用新型涉及三维打印技术领域，尤其涉及一种调平装置及三维打印设备。
背景技术
3D打印设备又称三维打印设备(3 Dimension Printer，3DP)，是一种累积制造技术，即快速成形技术的一种机器，它是一种数字模型文件为基础，运用特殊蜡材、粉末状金属或塑料等可粘合材料，通过依次打印多层的粘合材料来制造三维的物体。
在使用3D打印机进行打印的过程中，需要将成型平台和其下方的液晶显示(Liquid Crystal Display，LCD)屏幕进行对准贴合，才能打印出标准的物体。现有技术将成型平台调平的方式是通过在成型平台上安装调节螺母，通过调节螺母来调节成型平台与LCD屏幕的相对位置，然而该方式的步骤比较繁 琐，且误差大，容易在操作时伤及屏幕。可见现有的三维打印设备成型平台的调平方式便捷性较差。

除非另作定义，本实用新型中使用的技术术语或者科学术语应当为本实用新型所属领域内具有一般技能的人士所理解的通常意义。本实用新型中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也相应地改变。
参照图1至图7，本实用新型实施例提供了一种调平装置，应用于三维打印设备，所述三维打印设备包括悬臂100和成型平台300，所述调平装置200 包括连接件210和调节件220，所述连接件210的一端设置有球形连接部230，另一端与所述成型平台300可拆卸连接；所述悬臂100靠近所述连接件210的一侧向内凹陷形成球形容置腔，所述球形连接部230与所述球形容置腔适配，并容置于所述球形容置腔中；
所述调节件220可在第一位置和第二位置间移动，在所述第一位置，所述调节件220穿过所述连接件210，与所述悬臂100固定连接，以使所述成型平台300与所述悬臂100通过所述调平装置200固定；在所述第二位置，所述调节件220与所述悬臂100脱离固定，以使所述成型平台300与所述悬臂100通过所述调平装置200转动连接。
参照图1，图1为本实用新型实施例提供三维打印设备的部分结构示意图，其中，上述悬臂100可以通过直线滑块在垂直设置的导轨上滑动，从而带动成型平台300靠近或远离曝光屏幕。在三维打印设备工作过程中，上述成型平台300首先与曝光屏幕上设置的盛料盒的底端贴合，而后通过步进电机的牵引使得成型平台300逐渐远离曝光屏幕，将盛料盒中的材料由于光固化作用，通过成型平台300和曝光屏的配合逐步成型。因此，在三维打印设备开始工作之前，需要通过上述调平装置200将上述成型平台300调节至平整贴合于上述曝光屏幕上设置的盛料盒的底端的位置并进行固定，避免在打印过程中出现偏差。
在本实用新型实施例中，上述连接件210一端设置的球形连接部230可以容置于上述悬臂100的第一侧面向内凹陷形成的球形容置腔中，上述球形连接部230可在上述球形容置腔中转动，以带动上述连接件210基于上述球形连接部230转动。
应理解，为了便于上述球形连接部230与上述球形容置腔的安装，上述第一侧面可以开设有与上述球形连接部230适配的圆形开口，在上述球形连接部230容置于上述球形容置腔后，可以通过盖板或者其他固定件，限制上述球形连接部230仅在上述球形容置腔内转动，而不发生位移。
或者，在一可选的实施方式中，上述第一侧面与上述球形容置腔之间还可以设置有一段与上述球形连接部230适配的柱形通道，以便于上述球形连接部230通过柱形通道安装于上述球形容置腔内，并可以通过设置盖板，限制上述球形连接部230在沿柱形通道方向上位移的距离。
在另一可选的实施方式中，上述球形连接部230也可以与上述球形容置腔一体加工形成，这样，上述第一侧面上设置的开口直径可以小于上述球形连接部230的直径，从而上述球形连接部230可以在上述球形容置腔内转动，而由于开口的限制，不会发生位移。
上述连接件210与上述成型平台300之间的连接方式可以根据实际需要进行设置，在本实用新型实施例中，可以采用包括但不限于螺纹连接、卡扣连接或粘接的方式进行连接，在此不作进一步的限定。
上述调节件220可以通过在第一方向上的位移，来实现与上述悬臂100的固定与脱离固定。具体地，在一实用新型实施例中，上述调节件220与上述悬臂100的固定方式可以为螺纹连接；在另一实用新型实施例中，上述调节件220与上述悬臂100的固定方式也可以为在扣位触发卡扣的方式固定连接，具体可以根据实际需要进行设置。
应理解，上述调节件220可以穿过上述连接件210与上述悬臂100固定连接，并将上述连接件210与上述悬臂100进行固定。例如，上述连接件210上开设有贯通的螺纹孔，上述悬臂100上对应设置有螺纹孔，上述调节件220穿过上述连接件210的螺纹孔，与上述悬臂100上的螺纹孔配合固定，从而将上述连接件210与上述悬臂100进行固定，而不会发生转动。
又如，上述连接件210与上述球形连接部230上均可以设置有通孔，上述调节件220的一端可以同时穿过上述连接件210，与上述悬臂100设置的螺纹孔配合，另一端可以为螺丝头，将上述连接件210与上述悬臂100压紧固定。
而在将上述调节件220旋出上述悬臂100上的螺纹孔后，由于上述调节件220与上述悬臂100脱离固定，从而上述连接件210可以基于上述球形连接部230进行转动。
上述连接件210与球形连接部230的材料可以根据实际需要进行设置。在本实用新型实施例中，为了提升连接件210与球形连接部230的强度，且避免发生锈蚀，上述连接件210与上述球形连接部230均可以由不锈钢材料制成。当然，在其他可选的实施方式中，上述连接件210与上述球形连接部230可以由铜或者其他金属材料制成，也可以由塑料制成，在此不作进一步的限定。
本实用新型实施例通过调平装置200的连接件210一端设置的球形连接部 230与悬臂100的球形容置腔适配，并通过调节件220在第一位置和第二位置间的位移，从而在调节件220位于第一位置时，成型平台300与悬臂100通过调平装置200固定，在调平装置200位于第二位置时，成型平台300与悬臂100通过调平装置200转动连接，以球形连接部230为转动基点。由于用户在操作时仅需调节调节件220的位置至第二位置，即可以球形连接部230为基点，向各个方向转动成型平台300，在调平完成后调节调节件220的位置至第一位置完成成型平台300的固定，从而可以实现三维打印设备成型平台快速精确地调节位置，提升了三维打印设备成型平台调平的便捷性。
可选地，上述连接件210可以包括连接柱211和连接块212，上述连接柱211呈圆柱体设置，且一端与上述球形连接部230固定连接，上述连接块212上设置有与上述连接柱211适配的贯通孔，上述连接柱211部分容置于上述贯通孔中，并与上述连接块212固定连接。
一并参照图2至图4，在本实用新型实施例中，为了便于安装和拆卸，同时便于上述连接件210基于上述球形连接部230转动，上述连接件210可以包括连接柱211和连接块212，其中，连接柱211可以呈圆柱体设置，上述连接柱211的一端可以与上述球形连接部230固定连接，通过将连接柱211设置为圆柱体，可以在上述悬臂100开设的开口处自由转动，从而便于上述连接件210沿各个方向转动。应理解，为了实现上述连接柱211基于上述球形连接部230转动，上述连接柱211的外径可以小于上述球形连接部230的外径。
上述连接块212可以呈长方体设置，从而便于与上述成型平台300进行可拆卸连接。为了减小空间占用，上述连接块212上可以设置有与上述连接柱211适配的贯通孔，以使上述连接柱211部分容置于上述贯通孔内，从而减小了连接件210的长度。
上述连接块212与上述连接柱211的连接方式可以根据实际需要进行设置。例如，为了便于安装和拆卸，在一可选的实施方式中，上述连接块212可以与上述连接柱211通过由侧面旋入的螺钉进行固定。
当然，在其他可选的实施例中，上述连接柱211也可以不位于上述贯通孔内，而通过焊接等方式与连接块212固定连接，或者与上述连接块212一体成型。
与之类似地，上述球形连接部230与上述连接柱211之间可以通过焊接的方式固定连接。当然上述球形连接部230也可以与上述连接柱211一体成型，从而提升整体强度。
可选地，上述连接柱211可以呈圆筒形设置，上述球形连接部230对应上述连接柱211设置有贯通的第一通孔，上述球形容置腔的内壁上开设有第一螺纹孔；
上述调节件220为螺丝，在上述第一位置，上述调节件220依次穿过上述连接块212的贯通孔、上述连接柱211和上述第一通孔，与上述悬臂100通过上述第一螺纹孔固定连接，且通过上述调节件220的螺丝头将上述连接件210与上述悬臂100紧固。
参照图3至图4，在本实用新型实施例中，上述调节件220可以为螺丝，在第一位置与上述调节件220的第一螺纹孔配合固定。上述调节件220可以依次穿过上述连接块212的贯通孔、上述连接柱211和上述第一通孔，并通过上述调节件220的螺丝头将上述连接件210与上述悬臂100紧固，从而可以在第一位置实现上述连接件210与上述悬臂100之间的固定。
可以理解的是，上述连接块212的贯通孔、上述连接柱211和上述第一通孔的内径均大于上述调节件220螺杆的外径，从而在上述连接件210转动一定角度时，上述调节件220仍能穿过上述连接块212的贯通孔、上述连接柱211和上述第一通孔，与上述第一螺纹孔配合。
在上述调节件220由第一位置旋出至第二位置时，上述调节件220脱离上述第一螺纹孔，从而上述连接件210可以进行转动。
本实用新型实施例通过调节件220依次穿过上述连接块212的贯通孔、上述连接柱211和上述第一通孔，与上述悬臂100通过上述第一螺纹孔固定连接，且通过上述调节件220的螺丝头将上述连接件210与上述悬臂100紧固，从而通过调节件220在第一位置和第二位置间的移动，实现了上述连接件210与上述悬臂100之间的固定和转动连接，提升了调节成型平台300位置时的便捷性。
进一步地，上述调节件220上可以套设有限位件240，上述限位件240呈圆环设置，且圆环内径小于上述调节件220的螺丝头的外径，大于上述调节件220的螺杆的外径，在上述第一位置，上述限位件240的两端与上述连接柱211 的内壁和上述调节件220的螺丝头分别部分贴合。
在本实用新型实施例中，由于在上述连接件210转动一定角度后，上述连接块212的贯通孔、上述连接柱211和上述第一通孔形成的通道与上述第一螺纹孔之间会形成夹角，为了避免上述调节件220由于夹角而无法垂直旋入上述第一螺纹孔内的情况，上述调节件220上可以套设有呈圆环设置的限位件240，且圆环内径小于上述调节件220的螺丝头的外径，并可以略大于上述调节件220的螺杆的外径。
这样，在上述连接件210转动一定角度的情况下，在上述调节件220由上述第一位置运动到第二位置的过程中，上述限位件240一端与上述连接柱211的内壁抵接，并适应性地与上述连接柱211的端面形成与上述连接件210转动角度相同的角度，从而可以通过上述圆环的内环引导上述调节件220垂直旋入上述第一螺纹孔中，进一步提升了调平时的便捷性。
参照图5至图6，图6为图5的局部放大图。图5中的α角为上述连接件210可能的转动角，在连接件210转动α角的角度后，上述限位件240会向图6中的逆时针方向转动，图6中的β角为上述限位件240可能的转动角，其中，α角的角度和β角的角度相等。这样，上述调节件220仍会保持水平，从而在上述连接件210转动一定角度的情况下，调节件220仍可以垂直旋入上述第一螺纹孔中。
可选地，上述连接块212与上述悬臂100之间可以设置有悬臂盖400，上述悬臂盖400套设于上述连接柱211上，并与上述悬臂100固定连接。
在本实用新型实施例中，上述悬臂盖400可以通过螺丝与上述悬臂100进行固定，从而可以通过悬臂盖400限制上述球形连接部230沿上述连接柱211的延伸方向运动，而仅在上述球形容置腔内转动。
可以理解的是，由于上述悬臂盖400设置于上述连接块212与上述悬臂100之间，为了实现上述连接件210可以基于上述球形连接部230进行转动，上述悬臂盖400与上述连接块212之间可以存在一定的间隙，从而在上述连接件210在一定角度内转动时，不会被上述悬臂盖400遮挡位置。
进一步地，上述悬臂盖400上可以开设有第一开口，上述第一开口呈圆形设置，且上述第一开口的内径小于上述球形连接部230的外径，大于上述连接 柱211的外径。
在本实用新型实施例中，上述连接柱211可以穿过上述第一开口，由于上述第一开口的内径大于上述连接柱211的外径，从而连接件210可以上述第一开口的限制下，在一定角度内转动，可以避免成型平台300的转动角度过大而造成LCD屏幕损伤。
可选地，上述连接块212与上述成型平台300之间设置有支架500，上述支架500的一端与上述连接块212可拆卸连接，另一端与上述成型平台300可拆卸连接，上述连接块212与上述成型平台300通过上述支架500可拆卸连接。
在本实用新型实施例中，便于上述成型平台300的拆卸，从而方便取走三维打印后的产品，上述连接块212与上述成型平台300可以通过上述支架500可拆卸连接。
进一步地，上述支架500可以包括第一固定臂510、第二固定臂520和固定板530，上述固定板530的两端分别与上述第一固定臂510和上述第二固定臂520固定连接，上述第一固定臂510与上述第二固定臂520对称设置，且分别与上述成型平台300螺纹连接；
上述固定板530上可以开设有第一开孔，上述连接块212对应上述第一开孔设置有第二螺纹孔，上述连接柱211上对应上述第二螺纹孔开设有第二开孔，第一螺丝600依次穿过上述第一开孔、第二螺纹孔和第二开孔，将上述固定板530与上述连接块212固定。
参照图7，在本实用新型实施例中，上述支架500可以大致呈U型设置，包括第一固定臂510、第二固定臂520和固定板530。上述支架500可以通过第一固定臂510和第二固定臂520与上述成型平台300固定连接，而通过固定板530与上述连接块212可拆卸连接。这样，只需要将上述第一螺丝600旋出，即可解除上述支架500与连接件210之间的连接，便于取下上述成型平台300。
可选地，上述第一螺丝600远离上述固定板530的一侧可以设置有手柄，从而便于第一螺丝600的旋入和旋出。
上述第一固定臂510和第二固定臂520与上述成型平台300的连接方式可以根据实际需要进行设置。在一可选的实施方式中，上述第一固定臂510和第 二固定臂520可以与上述成型平台300通过焊接固定。当然，在其他实施例中，上述第一固定臂510和第二固定臂520也可以通过螺丝与上述成型平台300可拆卸连接。
进一步地，为了避免上述成型平台300在转动过程中发生晃动，上述第一固定臂510与上述第二固定臂520夹持上述连接块212，且上述第一固定臂510、第二固定臂520和上述固定板530可以分别与上述连接块212的三侧贴合。
可选地，为了实现上述连接块212与部分容置于上述连接块212的贯通孔中的连接柱211的固定，上述连接块212上可以开设有第三螺纹孔，上述连接柱211上对应上述第三螺纹孔开设有第四螺纹孔，第二螺丝依次穿过上述第三螺纹孔和上述第四螺纹孔，从而将上述连接块212与上述连接柱211限位固定。
本实用新型实施例还提供了一种三维打印设备，包括悬臂100、成型平台300和如上任一实施例所述的调平装置。由于本实用新型实施例提供的三维打印设备采用了上述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。
以上，仅为本实用新型的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本实用新型的保护范围之内。因此，本实用新型的保护范围应以权利要求的保护范围为准。
