Description

一种穿线机的拉线装置 技术领域
本实用新型涉及一种穿线机，尤其涉及一种穿线机的拉线装置。
背景技术
人们在使用网球拍(或羽毛球拍)进行体育活动时，球拍线的张力是影响击球效果和体验感的重要因素；因此，球拍穿线时对线的张力控制显得尤为重要。一般来说，球拍穿线时，首先用一个球拍固定装置将球拍固定，然后逐一穿线，线穿过球拍的过线孔后，再用一个拉线装置将线拉紧。
现有的拉线设备主要是电子式拉线装置，其区别于以往的手摇牵引式拉线装置，其通过电子技术控制低速电机，通过低速电机带动夹线器往复运动，达到将线拉紧或释放的目的。
然而，球拍线都有弹性，其张力会随着线的变形而改变，而线的微小变形会导致张力的较大变化。目前拉线装置的传动结构主要是固定于电机输出端的螺杆，夹线器和传感器固定于套设在螺杆上的螺母，使夹线器和传感器在低速电机控制下前进或后退；但是，该传动方式存在一个问题，即螺杆和螺母在运动的过程中会产生摩擦，长期使用后部件容易出现磨损，导致夹线器和传感器无法操持直线往返运动，使传感器测量出的拉力大小出现偏差，影响拉线的精准度。
实用新型内容
本实用新型的目的是提供一种穿线机的拉线装置，该穿线机的拉线装置有效解决了上述问题。
为了实现上述目的，本实用新型的技术方案是：
一种穿线机的拉线装置，其包括：夹线器、传感器、驱动元件、传动机构和控制电路；所述传感器与所述夹线器连接，用于检测所述夹线器所受的拉力，并将检测到的拉力值传送到所述控制电路；所述控制电路将检测到的拉力值与设定值进行比较，并根据比较结果控制所述驱动元件的转动；所述传动机构包括：安装座、传动滑块、传动齿条和驱动齿轮；所述驱动齿轮连接于所述驱动元件的输出端，所述传动齿条与所述驱动齿轮啮合且与所述传动滑块连接；所述安装座上设有导向柱，所述传动滑块套设于所述导向柱上，且与所述传感器连接；当所述传动滑块在所述驱动齿轮的驱动下，带动所述传感器和夹线器前进时，使球拍线被拉紧；当所述传动滑块在所述驱动齿轮的驱动下，带动所述传感器和夹线器后退时，使球拍线被放松。
作为一种具体的实施例，所述传动滑块设有导向孔，所述导向柱穿设于所述导向孔内。
所述导向孔内设有直线轴承，所述传动滑块通过所述直线轴承与所述导向柱连接。
进一步地，所述传动滑块的两端设置有垫片，所述垫片通过螺钉固定于所述传动滑块上，用于限制所述直线轴承的移动。
作为一种具体的实施例，所述夹线器包括：拉线座和夹紧块，所述拉线座与所述传感器连接，所述夹紧块滑动配合于所述拉线座上； 所述夹紧块的内侧线槽具有一倾斜坡度。
作为一种具体的实施例，所述驱动元件为电机。
进一步地，所述电机的输出端通过滚动轴承与所述驱动齿轮连接。
作为一种具体的实施例，该拉线装置还包括两个行程开关；所述安装座上设有两个侧板，所述行程开关分别设置在所述两个侧板上，当所述夹线器运动到前后极限位置时，所述行程开关向所述驱动元件发出停转信号。
作为一种具体的实施例，该拉线装置还包括与所述控制电路电性连接的显示器，所述显示器用于显示所述传感器所检测到的拉力值。
与现有技术相比，本实用新型具有以下技术效果：
本实用新型的穿线机的拉线装置，其传动机构包括安装座、传动滑块、传动齿条和驱动齿轮；驱动元件通过驱动齿轮，与传动齿条平稳配合，通过传动齿条带动夹线器和传感器直线运动，实现动力传递；另外，传动齿条通过传动滑块与夹线器和传感器连接，而传动滑块套设于安装座上的导向柱并沿导向柱滑动，其往返运动时产生的摩擦力远小于螺杆与螺母配合时产生的摩擦力，大大延长了产品的使用寿命，避免因夹线器摇晃而导致的拉力值测量不准确。
进一步，传动滑块与导向柱通过直线轴承配合，由于直线轴承与导向柱之间的摩擦为滚动摩擦，其摩擦力更小，使传动滑块保持平稳运动的同时，大大地减小了运动的阻力。
进一步地，为了将直线轴承更好地固定在传动滑块上，传动滑块的两端设置有用于限制直线轴承移动的垫片，垫片通过螺钉固定于所 述传动滑块上。
