使用时，将本发明所述的自适应跟随装置安装在钢轨铣磨装置上，其中所述底座16设置在钢轨铣磨装置的钢轨1上表面，且所述底座16的中心与所述钢轨1的中心相一致，所述定位合金块2紧贴设置于所述轨道16的内侧面，在进行铣磨操作时，所述底座16随着铣磨装置的移动沿所述钢轨1的上表面进行移动，则所述定位合金块2紧贴所述轨道16的内侧面随至进行跟随移动。When using, install the adaptive follow -up device described by the present invention on the rail milling and grinding device. The foundation 16 is set on the surface of the rail 1 of the rail milling and milling device, and the center of the base 16 is consistent with the center of the rail 1. As the base 16 moves along the upper surface of the rail 1 with the movement of the milling device, the positioning contract block 2 is closely followed by the inner side of the track 16 to follow the move.
在本实施例中，通过控制杠杆3的动作带动定位合金块2紧贴钢轨1移动，其中所述定位合金块2采用全圆弧接触结构，解决了钢轨1轨缝、肥边、塌边及钢轨错位而影响铣削及磨削正常加工的问题。In this embodiment, the movement of the control lever 3 drives the positioning alloy block 2 to move close to the rail 1, wherein the positioning alloy block 2 adopts a full-arc contact structure, which solves the problems of rail joints, fat edges, collapsed edges, and rail misalignment of the rail 1 that affect the normal processing of milling and grinding.
在本实施例中，通过气缸4的顶出实现在工作前与工作结束时定位合金块2与钢轨1表面分开，来避免在钢轨1出现肥边及塌边时，损坏精密侧向定位自适应跟随装置。In this embodiment, the positioning alloy block 2 is separated from the surface of the rail 1 before the work and at the end of the work through the ejection of the cylinder 4, so as to avoid damage to the precise lateral positioning self-adaptive follower when the rail 1 appears fat and collapsed.
在本实施例中，通过复位弹簧9压住复位销8使其始终顶在杠杆3上，从而实现在工作过程中，定位合金块2始终贴合钢轨1内侧面，随着钢轨1变化而自动跟随，通过限位块7限制杠杆3的移动位置，来实现定位合金块2在长期工作过程中磨损后杠杆3始终在中间位置。In this embodiment, the return spring 9 presses the reset pin 8 so that it is always on the lever 3, thereby realizing that during the working process, the positioning alloy block 2 is always attached to the inner surface of the rail 1, and automatically follows the change of the rail 1. The moving position of the lever 3 is limited by the limit block 7, so that the positioning alloy block 2 is always in the middle position after being worn out during long-term work.
在本实施例中，杠杆的后端通过圆柱销与导向轴13连接，导向轴安装在直线轴承内，利用直线轴承来改善导向轴摩擦状态，减小摩擦力，降低材料磨损，提高零件的使用寿命和工作性能。In this embodiment, the rear end of the lever is connected to the guide shaft 13 through a cylindrical pin, and the guide shaft is installed in a linear bearing. The linear bearing is used to improve the friction state of the guide shaft, reduce friction, reduce material wear, and improve the service life and performance of the parts.
通过导向轴13的一端与杠杆3连接实现对杠杆3的定位，同时导向轴13与杠杆的后端相连，导向轴13安装在直线轴承6内，利用直线轴承6来改善导向轴13的摩擦状态，减小摩擦力，降低材料磨损，提高零件的使用寿命和工作性能。通过在导向轴13的另一端安装两个接近开关15进行保护，工作过程中一个接近开关常亮，另一个为极限位置保护，这两个接近开关15与直线位移传感器11组合起到三层保护作用，接近开关15与数控系统相连，使得接近开关15的感应信号与数控程序相关联，当出现误操作或设备处于极限位置时，发出感应信号，进而通过数控系统控制气缸4工作自动顶开定位合金块2与钢轨1的接触，起到安全保护作用。The positioning of the lever 3 is realized by connecting one end of the guide shaft 13 with the lever 3. At the same time, the guide shaft 13 is connected with the rear end of the lever. The guide shaft 13 is installed in the linear bearing 6. The linear bearing 6 is used to improve the friction state of the guide shaft 13, reduce friction, reduce material wear, and improve the service life and work performance of the parts. Two proximity switches 15 are installed at the other end of the guide shaft 13 for protection. During work, one proximity switch is always on, and the other is limit position protection. The combination of these two proximity switches 15 and the linear displacement sensor 11 plays a three-layer protection role. The proximity switch 15 is connected to the numerical control system so that the induction signal of the proximity switch 15 is associated with the numerical control program.
在本实施例中，由于直线位移传感器11固定安装在位移传感器固定座10上，直线位移传感器11始终顶在杠杆3上，又由于直线位移传感器11到杠杆旋转中心与定位合金块2到杠杆旋转中心的距离相等，保证了定位合金块2接触到的钢轨变化量与直线传感器11的感应数据相同，直线传感器11与数控系统相连接，通过直线传感器11的数据反馈来精密控制钢轨铣磨装置的横向移动。In this embodiment, since the linear displacement sensor 11 is fixedly installed on the displacement sensor fixing seat 10, the linear displacement sensor 11 is always supported on the lever 3, and since the distance from the linear displacement sensor 11 to the center of rotation of the lever is equal to that of the positioning alloy block 2 to the center of rotation of the lever, it is ensured that the variation of the rail touched by the positioning alloy block 2 is the same as the sensing data of the linear sensor 11.
综上所述，本发明提供的用于钢轨铣磨装置侧向定位的自适应跟随装置，采用气缸加复位弹簧加杠杆的结构形式，解决了由于钢轨肥边、塌边严重时导致传统侧向定位装置无法正常定位的问题。To sum up, the self-adaptive following device for the lateral positioning of the rail milling and grinding device provided by the present invention adopts the structural form of the cylinder plus the return spring and the lever, which solves the problem that the traditional lateral positioning device cannot be positioned normally due to the fat edge and serious collapse of the rail.
