背景技术
因碳纤维材料成本较高， 由其制作的碳纤维产品基本上都为壳体， 制作时将多层碳纤维布包覆在与产品形状一致、 略小于产品尺寸的坯体 外制作成半成品， 再将其放到模具内充气、 加压、 加热， 让碳纤维层固 化， 再将坯体取出后得到碳纤维产品； 为了增加碳纤维产品的强度， 制 作碳纤维产品时相邻碳纤维布的纹理都要相互交错呈一定角度， 层层铺 叠以达到厚度才能满足产品所需的强度， 目前这些工作都需要手工操 作、 不但繁瑣， 且盾量不高、 得不到保证。 因此如何更快、 更平整、 紧 凑的包覆碳纤维层， 是业内人士急需解决的问题。
从下述生产带内胎的碳纤维自行车轮圈半成品的步骤中， 可以看出 包覆碳纤维的重要性， 步骤一： 制作与内胎形状一致、 尺寸略小于内胎 的芯轴， 内胎为环状； 步骤二， 将碳纤维布层剪切成条状， 其宽度刚好 可将芯轴环形包覆， 再一片一片的在环形芯轴上叠加若干层碳纤维布， 碳纤维布的纹理相互交错呈一定角度， 由于碳纤维层有粘胶， 为在包覆 时， 纤维布不相互干涉粘接在一起， 碳纤维布上有一层塑料膜， 贴覆时 需将塑料膜撕扯下来， 费时、 费工； 同时为了包覆更加均匀平整、 无气 泡，条状的碳纤维布不能太长， 为了达到产品所需厚度， 只能分断多次、 多层的重复包覆， 由于内胎芯轴较大、较重， 工人操作时都需长久站立， 包覆一个内胎芯轴需用花 2-3个小时才能完成； 步 三、 为了让包覆的 碳纤维层平整、 紧凑、 不松散 > 还需在上述包覆好的坯品外层缠绕碳纤 维带紧固制成内胎坯， 这些工作都需工人操作。
由上描述可知， 单单包覆一个内胎芯轴就需要花费 2- 3小时， 不但 耗时、 费力、 还不能保证碳纤维层的平整度， 紧密度、 厚度的均匀， 而 这些直接影响产品强度、 性能的和盾量； 为了满足产品的宽度、 长度及 纹理要求， 纤维布不断被裁剪， 材料浪费较大， 又因碳纤维布不可回收 再用， 为了降低成本、 减小对环境的影响， 需提高材料的利用率。
发明内容
为了解决背景技术所存在的技术问题， 本发明提供一种给环形芯 轴缠绕碳纤维纱的方法， 具有简单可靠、 提高生产效率、 降低废品率、 生产的轮圈产品碳纤维层平整、 不会变形、 能有效控制产品尺寸、 使 用强度高、 节省碳纤维布等优点。
本发明还提供了一种用于上述方法的缠纱设备， 该设备可以自动 给环形芯轴缠绕碳纤维纱、缠绕的碳纤维层每层纱的紋理都相互交错呈 一定角度， 而且碳纤维层平整、 紧密度高， 由此加工的产品强度高、 质 量有保证， 而且碳纤维材料可充分利用， 因此具有省工、 省时、 降低成 本、 产品品质高等优点。
本发明解决其技术问题所采用的方法是： 一种给环形芯轴缠绕碳 纤维纱的方法， 包括：
步骤一： 盘纱制作，将碳纤维带层层缠绕在线轴上制成盘纱； 步驟二： 环形芯轴定位， 动力转子与定位转子相配夹持环形芯轴 的内、 外缘将环形芯轴垂直悬空定位， 限定环形芯轴不能径向、 轴向移 动；
步骤三： 环形芯轴自转， 至少三个动力转子抵压在芯轴内缘， 动 力转子由电机一输出轴带动自转， 自转的同时通过摩擦力带动环形芯轴 自转；
步骤四：缠纱， 盘纱以芯轴壁体为中心水平转动， 将碳纤维带层 层缠绕在芯轴上。
所述的盘纱其碳素纤维带宽度为 8- 12cm，角度为 45- 75度， 碳纤维 带之间通过塑料胶带防粘；
所述的环形芯轴为刚性的， 不易变形。
所述的盘纱有两个， 分别固定在左、 右转盘上， 左、 右转盘分别由 电机二的输出轴带动旋转。
所述的左、 右转盘上还设有收缠塑料胶带的自转销， 自转销由电机 三的输出轴带动转动。
本发明解决其技术问题所采用的技术方案是： 一种给环形芯轴缠绕 碳纤维纱的设备， 包括相互垂直的水平工作台和竖直工作台， 至少三对 动力转子及与之相配垂直悬空定位环形芯轴的定位转子， 动力转子和定 位转子设置在竖直工作台上， 动力转子由电机一输出轴带动自转； 水平 工作台设有左、 右转盘， 左、 右转盘上分别设有让环形芯轴穿过的让位 孔及缺口， 让位孔及缺口连通， 让位孔的孔心与转盘的圆心重合， 左、 右转盘的让位孔的孔距等于环形芯轴的中心线的直径， 左、 右转盘分别 由电机二的输出轴带动旋转； 两个由碳素纤维带制成的盘纱分别固定在 左、 右转盘上， 在转盘旋转的带动下盘纱分别围绕转盘的让位孔的圓心 水平旋转。
在优选的实施结构中：
所述的定位转子上设有限定环形芯轴轴向移动的、 且与环形芯轴壁 体相配的环形凹槽， 定位转子通过支臂与定位转子固定座联接， 支臂可 沿固定座移动； 定位转子的凹槽保证环形芯轴在转动时不偏离轨道， 且 通过支臂的移动调节芯轴与动力转子的摩擦力。
所述的动力转子与定位转子相配端设为阶梯轴， 小轴与定位转子的 凹槽相配限定环形芯轴轴向、 径向移动， 动力转子的另一端为同轴心的 皮带轮， 电机一输出轴通过皮带带动皮带轮转动。
所述的左、 右转盘结构一致， 转盘底部为竖齿结构， 上部外缘设成 为环形 V型槽， 至少三个设置在水平工作台上的转盘定位转子卡设在 V 型槽，将转盘水平悬空定位， 并限制转盘受外力轴向及径向移位； 在左、 右转盘的缺口两侧均分别设有主动齿轮和从动齿轮， 主动齿轮与从动齿 轮均与转盘的竖齿相啮合， 主动齿轮由电机二输出轴带动旋转， 并通过 皮带带动从动齿轮。 由于在转盘缺口两侧设有主动齿轮和从动齿轮， 二 者通过皮带轮相连， 这样当主动齿轮和从动齿轮与转盘啮合， 并带动其 转动时， 不会因主动齿轮或从动齿轮遇到转盘的缺口， 而影响转盘转动 的速度。
所述的转盘定位转子通过固定座设置在水平工作台上， 为减少转盘 转动时与之的摩擦阻力， 它与固定座之间设有轴承。 所述的左、 右转盘上还设有收缠塑料胶带的自转销， 自转销随着转 盘转动的同时， 在电机三的输出轴带动下自转。
由上述技术方案可知， 环形芯轴与动力转子、 定位转子相配， 限定 了它轴向、 径向的移动空间， 因此当与电机的输出轴传动联接的动力转 子抵压在环形芯轴的内缘时， 动力转子自转的同时靠摩擦力带动芯轴转 动， 由于三点确定一个圆， 环形芯轴由至少三个动力转子与定位转子限 位， 因此它只能是围绕三点确定的圓心自转； 而设置在水平工作台台面 的左、 右转盘的让位孔的孔距等于环形芯轴中心线的直径， 当环形芯轴 垂直悬挂， 并将环形芯轴的中心线水平两端点与左、 右转盘的中心孔的 圆心重合， 由于转盘上均设有围绕中心孔圆心旋转的碳素纤维带制成的 盘纱， 而碳纤维带的始端固联在环形芯轴上， 因此当转盘在主动齿轮的 带动下转动时， 盘纱将围绕设置在转盘让位孔的环形芯轴转动， 于是碳 纤维带将层层缠绕在芯轴的壁体上， 而芯轴在动力转子的带动下勾速自 转， 碳纤维带将始终以同一角度均勾的缠绕在芯轴壁体上； 由于左、 右 两侧的转盘均设在工作台水平台面上， 两个盘纱在对芯轴缠绕时角度呈 交错， 从而满足产品碳纤维层缠纱的要求。
由此可本发明的优点有：
一、 连续缠绕、 制造工艺简便、 减少人工缠纱的人力和时间， 提 高了生产效率；
二、 由于机台转速均匀稳定、 缠纱的力度和间距均匀， 克服已有 技术缠纱不平整的缺陷， 从而让成型产品的刚性和强度有很 好的保证， 不但降低废品率、 使产品的碳纤维层平整、 壁厚 均匀、 不会变形、 还能有效控制产品尺寸； 而且由于采用产 品连续缠绕成型整个管壁内外材质均匀， 无搭接现象， 使产 品的碳纤维层平整、 壁厚均匀、 不会变形、
三、 由于碳素纤维带是整条， 不需时时剪裁， 简化原料、 节省原 材料；
四、 产品成本降低；
五、 改变芯轴的转速， 纱与芯轴的角度及相邻两层紗交错的均为 可变的， 以满足各种产品的性能。
六、 改就盘纱与芯轴的角度， 同样可以改变相邻两层纱交错的均 为可变的， 以满足各种产品的性能强度要求。

具体实施方式
本发明解决其技术问题所采用的技术方案是： 一种给环形芯轴缠 绕碳纤维纱的方法， 包括：
步骤一： 盘纱 8制作，将碳纤维带层层缠绕在线轴 81上制成盘纱 8 , 碳素纤维带 82宽度为 10cm，角度为 50度, 碳纤维带 82之间通过塑 料胶带 83防粘； 所述的环形芯轴 4为刚性的， 不易变形的；
步骤二： 环形芯轴 4定位， 至少三个动力转子 3与定位转子 2相 配夹持环形芯轴 4的内、 外缘将环形芯轴 4垂直悬空定位， 限定环形芯 轴 4不能径向、 轴向移动；
步骤三：环形芯轴 4 自转，动力转子 3抵靠在环形芯轴 4的内缘， 动力转子 3由-电机一的输出轴带动自转， 其自转的同时通过摩擦力带动 环形芯轴 4 自转；
步骤四：缠纱， 盘纱 8以环形芯轴 4壁体为中心转动， 将碳纤维带 层层缠绕在环形芯轴 4上； 盘纱 8有两个， 分别设置在环形芯轴 4的左 右两侧。
一种给环形芯轴缠绕碳纤维纱的设备， 如图 1、 图 2所示， 包括： 设有相互垂直的水平工作台 1 1及竖直工作台 12 ,水平工作台 1 1有两个， 处于同一高度， 并分别设定在竖直工作台 12的两侧；
四对定位转子 2及与之相配垂直悬空定位环形芯轴 4的动力转子 3 , 动力转子 3和定位转子 2均设置在竖直工作台 12上， 定位转子 2设有 环形凹槽 21 , 四个动力转子 3与定位转子 2相配端为阶梯轴， 其小端 30与定位转子 1的环形凹槽 21相配可将环形芯轴 4卡设在它们构成的 凹腔内， 即由动力转子 2与定位转子 3相配构成的的四个凹腔确定一个 圆环， 该圆环与环形芯轴的内、 外圓重合， 这样由于在凹腔的限制下环 形芯轴在转动时不会偏离轨道； 由此可知环形芯轴 4由动力转子 3与定 位转子 1相配悬挂在竖直工作台 12上， 二者相平行， 动力转子 3抵压 在环形芯轴 4的内缘壁体上， 动力转子 3的另一端穿过竖直工作台 Π 并设置为与阶梯轴同轴心的皮带轮 31， 动力转 3子的四个皮带轮 31通 过皮带 5与电机一 6的输出轴传动联接，也就是说电机一 6的输出轴 61 通过皮带 5带动皮带轮 31转动， 从而带动动力转子 3转动， 如图 2所 示； 同时动力转子 3通过摩擦力带动环形芯轴 4转动； 与动力转子相配 的定位转子通过支臂 22与定位转子固定座 23联接， 定位转子固定座设 置竖直台面 12上， 定位转子 2的支臂 22可沿固定座的导轨 24左右移 动， 以调节环形芯轴 4与动力转子 3的摩擦力； 为了减少阻力， 定位转 子 2套接在支臂 22末端的轴杆 25上， 受到外力时可以自转；
如图 3、图 4所示，左、右转盘 7上设有固定盘纱 8的碳纱转轴 700 , 盘纱 8的线轴中空为通孔， 其通孔孔径与转轴 700相配， 组装时， 将盘 纱套装在碳纱转轴上即可， 在转盘旋转的带动下盘纱分别围绕转盘的中 心孔的圆心水平旋转； 左、 右转盘上分别设有让环形芯轴穿过的让位孔 70及缺口 71， 让位孔 70及缺口 71连通， 让位孔的孔心与转盘的圓心 重合， 左、 右转盘 7的两个让位孔 70的孔距等于环形芯轴 4的中心线 401的直径， 且其中心点 702、 703分别与环形芯轴的中心线水平点 A、 B重合， 如图 6所示； 转盘 7底部为竖齿 72结构， 上部外缘 7 3设有环 形的 V型槽 731 , 左、右转盘上均有三个设置在水平工作台 1 1上的转盘 定位转子 74卡设在 V型槽 731 内， 将转盘 7水平悬空定位， 并限制转 盘 7受外力轴向及径向移位； 在左、 右转盘 7的缺口 71两侧均分别设 有主动齿轮 9和从动齿轮 10, 主动齿轮 9与从动齿轮 10均与转盘 7的 竖齿相啮合， 主动齿轮 9由电机二输出轴带动旋转， 并通过皮带 5， 带 动从动齿轮 9 , 由于在转盘缺口 71两侧设有主动齿轮 9和从动齿轮 10, 二者通过皮带轮 5， 相连， 这样当主动齿轮 9和从动齿轮 10与转盘 7 啮合， 并帶动其转动时， 不会因主动齿轮 9或从动齿轮 10遇到转盘的 缺口 71 , 而影响转盘 7转动的速度。 转盘定位转子 74通过固定座 742 设置在水平工作台上， 转盘定位转子 74设有与转盘的 V 形槽 731相配 的凸缘 741为了减少转盘 7转动时与转盘定位转子 74的摩擦阻力， 转 盘定位转子 74与固定座 742之间设有轴承 743, 如图 5所示；
所述的转盘上还设有收缠塑料胶带 83 的自转销 701 , 自转销 701 随着转盘 7转动的同时，在电机三的输出轴的带动下自转，如图 3所示， 自转销 701收缠塑料胶带的速度与碳纤维层缠绕在环形芯轴的速度要互 相匹配， 以保证收和缠协调一致。
由上述技术方案可知， 缠纱时， 环形芯轴 4定位后， 将盘纱 8装在 转盘 7的凸轴，再将盘纱 8的始端缠绕在环形芯轴 4的壁体上，并固定； 因动力转子 3、 定位转子 4相配， 限定了环形芯轴 4轴向、 径向的移动 空间， 因此当与电机转轴传动联接的动力转子 3, 抵靠在环形芯轴 4的 内缘， 并靠摩擦力带动环形芯轴 4转动时， 环形芯轴只能是围绕圆心自 转； 而设置在工作台 1水平台面 11上的左、 右转盘 7的中心距为环形 芯轴 4的中心环直径 D， 当环形芯轴 4悬挂， 中心线的水平直径的端点 置于左、 右转盘 7的中心点时， 因此当转盘 7在主动齿轮 9的带动下 转动时， 盘纱 8将围绕转盘中心 （即处于之处的环形芯轴壁体）转动， 碳纤维带将层层缠绕在环形芯轴 4的壁体上， 而环形芯轴 4在动力转子 3的带动下角带度均匀的自转， 因此碳纤维带将始终以同一角度均匀的 缠绕在芯轴壁体上， 由于左右两侧的转盘 7均设在工作台水平台面上， 两个盘纱 8在对环形芯轴 4缠绕时角度呈交错， 从而满足碳纤维层强度 的要求。
以上所述， 仅为本发明较佳实施例而已， 故不能以此限定本发明实 施的范围， 即依本发明申请专利范围及说明书内容所作的等效变化与修 饰， 皆应仍属本发明专利涵盖的范围内。
