Description

一种高强度自挤螺栓
技术领域
本发明涉及一种螺栓，特别涉及一种高强度自挤螺栓。
背景技术
螺栓在平常的生活中的应用十分的广泛，是一种十分常用的紧固件，螺栓也被称为工业之米，可见螺栓的运用之广泛，螺栓的运用范围有：电子产品，机械产品，数码产品，电力设备，机电机械产品，船舶，车辆，水利工程，甚至化学实验上也有用到螺栓，总之很多地方都有用到螺栓的，特如数码产品上面用到的精密螺栓，DVD，照相机、眼镜、钟表、电子等使用的微型螺栓，电视、电气制品、乐器、家具等之一般螺栓，至于工程、建筑、桥梁则使用大型螺栓、螺帽；交通器具、飞机、电车、汽车等则为大小螺栓并用，螺栓在工业上负有重要任务，只要地球上存在着工业，则螺栓之功能永远重要。现有的螺栓为一体式结构，在使用过程中经常会出现螺栓头因受力不均而变形的情况，影响螺栓的使用。另外在大铸件时，铸铁件上需通过螺栓连接其他部件，因铸件不能直接铸出螺纹，一般都会事先钻出坯孔后再制成螺纹，工序繁多，时间和人力成本较大。
发明内容
本发明的目的就在于提供一种结构设计新颖、合理，成本较低，使用方便的高强度自挤螺栓。
为了实现上述目的，本发明采用的技术方案是这样的：本发明的高强度自挤螺栓，包括螺栓头和螺杆，螺杆上设置有外螺纹，所述螺杆上外螺纹处设置有数个条形槽，数个条形槽呈螺旋状均布在螺杆上，螺杆顶面设置有凹槽，螺杆顶部侧面设置有条形缺口，所述螺栓头顶面设置有十字型槽和一字型槽，螺栓头底面设置有与凹槽对应的凸起，螺栓头底面边缘设置有与条形缺口相匹配的条形块，螺栓头通过凸起和条形块与螺栓固定。
作为优选，所述螺杆上外螺纹表面设置有防磨层。
作为优选，所述十字型槽和一字型槽同轴设置，一字型槽设置于十字型槽下方。
与现有技术相比，本发明的优点在于：本发明结构设计新颖、合理，螺杆上设置螺纹和条形槽，铸铁件在钻出坯孔后无需在坯孔内制出螺纹，自挤螺栓直接用电动设备进行自挤攻牙，这时在自攻时，铸件的碎屑可以从条形槽中就排泄出来，可使自攻作业更加省力、快捷，该螺栓自攻出来的螺牙，能与螺栓本身紧密连接，紧固效果更好；螺栓头和螺杆可拆卸连接，可更换螺栓头，使用方便，成本较低，螺杆上设置防磨层，使螺栓强度更高。
附图说明
图1为本发明的结构示意图；
图2为本发明的剖面图。
具体实施方式
下面将结合附图对本发明作进一步说明。
参见图1和图2，本发明的高强度自挤螺栓，包括螺栓头1和螺杆2，螺杆2上设置有外螺纹3，所述螺杆2上外螺纹3处设置有数个条形槽4，数个条形槽4呈螺旋状均布在螺杆2上，螺杆2顶面设置有凹槽，螺杆2顶部侧面设置有条形缺口，所述螺栓头1顶面设置有十字型槽7和一字型槽8，螺栓头1底面设置有与凹槽对应的凸起6，螺栓头1底面边缘设置有与条形缺口相匹配的条形块5，螺栓头1通过凸起6和条形块5与螺栓固定，所述螺杆2上外螺纹3表面设置有防磨层9，所述十字型槽7和一字型槽8同轴设置，一字型槽8设置于十字型槽7下方。
螺杆2上设置螺纹和条形槽4，铸铁件在钻出坯孔后无需在坯孔内制出螺纹，自挤螺栓直接用电动设备进行自挤攻牙，这时在自攻时，铸件的碎屑可以从凹槽中就排泄出来，可使自攻作业更加省力、快捷，该自挤螺栓自攻出来的螺牙，能与螺栓本身紧密连接，紧固效果更好；螺栓头1和螺杆2可拆卸连接，可更换螺栓头1，本发明结构设计新颖、合理，使用方便，成本较低，螺杆2上设置防磨层9，使螺栓强度更高。
