Description

一种激光拼焊预定位机构 技术领域
本申请涉及一种激光拼焊预定位机构，属于激光拼焊设备技术领域。
背景技术
在待焊板材进行激光拼焊加工之前，需要对待焊板材进行预定位，之后再将板材送至加工位置，以提高加工精度；而现有的预定位机构的结构不够合理，不能满足定位精度的需求，定位部件不能根据实际需要进行调节。
发明内容
针对上述存在的技术问题，本申请的目的是：提出了一种激光拼焊预定位机构。
本申请的技术解决方案是这样实现的：一种激光拼焊预定位机构，包含安装架，安装架上设置有两个定位安装座，一个定位安装座上设置有前侧感应组件，另一个定位安装座上设置有前侧感应组件和侧边感应组件；所述前侧感应组件包含传感器安装座和定位传感器，所述侧边感应组件包含侧定位挡块和定位传感器。
优选的，所述定位传感器为接近开关，接近开关安装在传感器安装座的后侧，传感器安装座的前侧设置有弹簧柱，弹簧柱与接近开关配合。
优选的，所述侧定位挡块通过旋转轴转动设置在定位安装座上，侧边感应组件的定位传感器设置在侧定位挡块的后侧，侧定位挡块的前端被触碰后会微转动，使其后端触发定位传感器。
优选的，所述安装架上还设置有导轨和孔排座，一个定位安装座与导轨和孔排座滑动配合，该定位安装座上设置有旋钮柱塞，孔排座上设置有 多个定位孔，旋钮柱塞与孔排座上的定位孔配合。
优选的，所述安装架上还设置有丝杆传动副，丝杆传动副包含导轨、丝杆和把手组件，一个定位安装座与该丝杆传动副配合。
优选的，所述把手组件包含旋转把手和数显器，旋转把手通过数显器与丝杆配合。
由于上述技术方案的运用，本申请与现有技术相比具有下列优点：
本申请优化设计了定位部件，在两个定位安装座上各设置一组前侧感应组件，并在其中一个定位安装座上设置一组侧边感应组件，使整体可以对待焊板材的前侧部的两个位置，以及一个角的侧边进行定位，三点预定位的方式保证了定位精度，提高良品率；且定位安装座可以根据实际需要进行调整，以适应不同的工作环境，以及不同尺寸板材的需要。
附图说明
下面结合附图对本申请技术方案作进一步说明：
图1为本申请所述的一种激光拼焊预定位机构的立体结构示意图。
具体实施方式
下面结合附图来说明本申请。
如图1所示，本申请所述的一种激光拼焊预定位机构，包含安装架1，安装架1上设置有两个定位安装座2，一个定位安装座2上设置有第一前侧感应组件，另一个安装座2上设置有第二前侧感应组件和侧边感应组件；每个所述前侧感应组件包含传感器安装座3和定位传感器4，侧边感应组件包含侧定位挡块5和定位传感器4。
所述定位传感器4为接近开关，接近开关安装在传感器安装座3的后侧，传感器安装座3的前侧设置有弹簧柱6，弹簧柱6与接近开关配合；所 述侧定位挡块5通过旋转轴7转动设置在定位安装座2上，侧边感应组件的定位传感器4设置在侧定位挡块5的后侧，侧定位挡块5的前端被触碰后会微转动，使其后端触发定位传感器4。
所述安装架1上还设置有导轨8、孔排座9、丝杆11和把手组件，其中导轨8、丝杆11和把手组件组成一个丝杆传动副，两个定位安装座2共用导轨8；其中一个定位安装座2(图中右侧)与导轨8和孔排座9滑动配合，该定位安装座2上设置有旋钮柱塞10，孔排座9上设置有多个定位孔，旋钮柱塞10与孔排座9上的定位孔配合，另一个定位安装座2(图中左侧)与丝杆传动副配合；所述把手组件包含旋转把手12和数显器13，旋转把手12通过数显器13与丝杆11配合。
待焊板材在定位时，外部机械手先向前推动板材料片，料片将两个前侧感应组件的弹簧柱6向里压缩，到位置后传感器触发，此时判定料片前侧到位，并且待焊板材没有歪斜；再次将料片向左推触碰侧定位挡块，挡块绕旋转轴7旋转，触碰后部的接近传感器，以此判定料片的侧部到位。
两组定位安装座2根据料片的大小调整之间的距离，通过旋转把手12和丝杠11可将一组侧定位安装座2向左右方向移动，此定位安装座2位置为基准，根据数显器可判定移动距离，移动距离单位为0.1mm；另一组定位安装座2左右调整时，可拔起旋转柱塞10任意移动，通过孔排座9固定其位置。
上述实施例只为说明本申请的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本申请的内容并加以实施，并不能以此限制本申请的保护范围，凡根据本申请精神实质所作的等效变化或修饰，都应涵盖在本申请的保护范围内。
