Description

一种计量线收卷器
技术领域
本发明涉及一种应用于工程机械领域的计量线收卷器。
背景技术
很多的设备都需要用到收卷器，如起重机，它往往需要用吊绳将重物吊起一定高度，然后对重物进行安装，由于其收卷器无法进行精确的计量吊绳的收放长度，所以不能以吊绳作为计量线对重物进行精确的高度调整，故现有的起重机的吊起高度往往需要人工花大量的时间进行调节；再如一些数控设备，需要用钢丝、钢线配合收卷器牵引相关设备，让相关的设备进行位置的调整，这些数控设备都用钢丝、钢线作为计量线对相关设备所谓位置进行精确的计算，但是它们的钢丝、钢线与收卷器的接触点会沿收卷器的转轴的延伸方向不断变化，若收卷器的转轴是左右设置的，那么所述接触点就会左右移动，从而产生一个不固定的摆角，导致钢丝、钢线与收卷器的转轴的夹角不断地变化，故设计人员需要在数控***中预设好非常复杂的计算公式来弥补所述夹角变化而带来的误差，这样的计算公式会产生大量的浮点运算，大大地加重CPU的计算工作量，让整个数控***运行缓慢，同时大量的浮点运算会累积误差，导致钢丝、钢线所牵引的设备定位精度大大下降。
发明内容
本发明要解决的技术问题是：提供一种计量线收卷器。
本发明解决其技术问题的解决方案是：
一种计量线收卷器，包括收卷器本体，收卷器本体内设有联动转轴，收卷器本体上固化有连动孔，联动转轴上设有外螺纹，连动孔的孔壁上设有与所述外螺纹相适配的螺旋结构，连动孔与所述外螺纹连接，使得收卷器本体能以联动转轴为轴心转动的同时能让收卷器本体能沿联动转轴的延伸方向移动；收卷器本体上设有螺旋状的藏线槽，藏线槽的螺距与所述外螺纹的螺距等值，藏线槽的旋向与所述外螺纹的旋向相同，藏线槽沿联动转轴的延伸方向旋进。
作为上述方案的进一步改进，收卷器本体呈圆柱形，联动转轴设在收卷器本体的轴线上。
作为上述方案的进一步改进，还包括基架，收卷器本体设在基架上，基架上还设有具有输出转轴的驱动模块，输出转轴与收卷器本体连接，使得输出转轴可带动收卷器本体转动。
作为上述方案的进一步改进，还包括同步带，输出转轴和收卷器本体上均设有与同步带连接的同步带轮。
作为上述方案的进一步改进，还包括基架和导向组件，收卷器本体通过导向组件与基架上连接。
作为上述方案的进一步改进，所述导向组件包括滑动连接在一起的滑块和滑轨，滑块与收卷器本体固定连接，滑轨与基架连接。
作为上述方案的进一步改进，还包括定向轮，所述定向轮与基架连接，定向轮设在收卷器本体的旁侧。
作为上述方案的进一步改进，定向轮与基架用转轴连接。
作为上述方案的进一步改进，还包括固化在收卷器本体上的丝杆螺母，所述连动孔即为丝杆螺母的工作孔，所述联动转轴为丝杆。
本发明的有益效果是：一种计量线收卷器，包括收卷器本体，收卷器本体内设有联动转轴，收卷器本体上固化有连动孔，联动转轴上设有外螺纹，连动孔的孔壁上设有与所述外螺纹相适配的螺旋结构，连动孔与所述外螺纹连接，使得收卷器本体能以联动转轴为轴心转动的同时能让收卷器本体能沿联动转轴的延伸方向移动；收卷器本体上设有螺旋状的藏线槽，藏线槽的螺距与所述外螺纹的螺距等值，藏线槽的旋向与所述外螺纹的旋向相同，藏线槽沿联动转轴的延伸方向旋进。工作时，外设的计量线与收卷器本体连接，收卷器本体的转动会让计量线会落入藏线槽中，从而实现计量线的精确收卷，也能避免计量线之间的相互摩擦而导致的计量线损伤，计量线的损伤严重会导致其弹性模量产生较大的变化，导致定位不精确，由于藏线槽与外螺纹的螺旋的螺距和螺旋方向一致，故在计量线落入藏线槽的同时收卷器本体也会做沿联动转轴的延伸方向移动，使得计量线与收卷器的接触点不会沿联动转轴的延伸方向移动，让计量线与联动转轴的夹角始终不变，避免了所述夹角的变化带来的误差。本发明用于计量线的收卷。
附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单说明。显然，所描述的附图只是本发明的一部分实施例，而不是全部实施例，本领域的技术人员在不付出创造性劳动的前提下，还可以根据这些附图获得其他设计方案和附图。
图1是本发明实施例的收卷器和驱动模块的放置示意图；
图2是本发明实施例的俯视示意图；
图3是本发明实施例的主视示意图；
图4是本发明实施例的左视示意图。
具体实施方式
以下将结合实施例和附图对本发明的构思、具体结构及产生的技术效果进行清楚、完整地描述，以充分地理解本发明的目的、特征和效果。显然，所描述的实施例只是本发明的一部分实施例，而不是全部实施例，基于本发明的实施例，本领域的技术人员在不付出创造性劳动的前提下所获得的其他实施例，均属于本发明保护的范围。另外，文中所提到的所有联接/连接关系，并非单指构件直接相接，而是指可根据具体实施情况，通过添加或减少联接辅件，来组成更优的联接结构。本发明中的各个技术特征，在不互相矛盾冲突的前提下可以交互组合。
参照图1至图4，这是本发明的一个实施例，具体地：
一种计量线收卷器，包括收卷器本体2，收卷器本体2内设有联动转轴21，收卷器本体2上固化有连动孔，联动转轴21上设有外螺纹，连动孔的孔壁上设有与所述外螺纹相适配的螺旋结构，连动孔与所述外螺纹连接，使得收卷器本体2能以联动转轴21为轴心转动的同时能让收卷器本体2能沿联动转轴21的延伸方向移动；收卷器本体2上设有螺旋状的藏线槽，藏线槽的螺距与所述外螺纹的螺距等值，藏线槽的旋向与所述外螺纹的旋向相同，藏线槽沿联动转轴21的延伸方向旋进。工作时，外设的计量线与收卷器本体连接，收卷器本体的转动会让计量线会落入藏线槽中，从而实现计量线的精确收卷，也能避免计量线之间的相互摩擦而导致的计量线损伤，计量线的损伤严重会导致其弹性模量产生较大的变化，导致定位不精确，由于藏线槽与外螺纹的螺旋的螺距和螺旋方向一致，故在计量线落入藏线槽的同时收卷器本体也会做沿联动转轴的延伸方向移动，使得计量线与收卷器的接触点不会沿联动转轴的延伸方向移动，让计量线与联动转轴的夹角始终不变，避免了所述夹角的变化带来的误差。
计量线所控制的设备的终端位移一般是呈线性的，故收卷器本体2呈圆柱形，联动转轴21设在收卷器本体2的轴线上。而一些特殊的设备，它需要经过一些凸轮、可产生往复式移动的连杆连接，这些设备终端的位移往往不是线性的，故可根据使用要求，让收卷器本体2的横截面呈椭圆形等其他形状。
为了让使用本发明的设备的设计人员能专心设计他们的设备，也为了确保本发明的精确度，本实施例还包括基架，收卷器本体2设在基架上，基架上还设有具有输出转轴22的驱动模块1，输出转轴22与收卷器本体2连接，使得输出转轴22可带动收卷器本体2转动。
为了提供精度，本实施例还包括同步带，输出转轴22和收卷器本体2上均设有与同步带连接的同步带轮。
为了防止本发明在工作时联动转轴21受到较大的力而产生变形而导致误差，还包括基架和导向组件，收卷器本体2通过导向组件与基架上连接，导向组件可承担大部分的工作力，避免联动转轴21在工作时出现微量的弯曲而导致的误差，导向组件的加入，可让联动转轴21仅负责位置的传动和收转，大大地提高了传动精度。
为了节省成本，同时减少让联动转轴21受到的工作力，所述导向组件包括滑动连接在一起的滑块31和滑轨32，滑块31与收卷器本体2固定连接，滑轨32与基架连接。
在装配过程中，由于种种原因，计量线有可能与藏线槽的边缘发生刮蹭，导致计量线的损伤，故本发明还包括定向轮4，所述定向轮4与基架连接，定向轮4设在收卷器本体2的旁侧，可调节定向轮4的位置，让计量线不会与藏线槽的边缘发生刮蹭。
为了减少计量线与定向轮4的摩擦，定向轮4与基架用转轴连接。
本实施例还包括固化在收卷器本体2上的丝杆螺母，所述连动孔即为丝杆螺母的工作孔，所述联动转轴21为丝杆，丝杆传动的工艺较为成熟，成本相对低廉，能满足大部分的设备对精度的要求。
以上对本发明的较佳实施方式进行了具体说明，但本发明并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出种种的等同变型或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
