Abstract

本实用新型涉及一种螺栓套丝工具，特别涉及一种凹槽内紧固螺栓的套丝工具。主要解决现有套丝扳牙在凹槽内无法操作的技术问题。本实用新型的技术方案为：一种凹槽内紧固螺栓的套丝工具，为一只扳牙套座，扳牙套座外径小于凹槽直径，扳牙座套的内孔中装有套丝圆扳牙，扳牙套座上部为外六角帽，与套筒扳手的内六角相匹配。扳牙套座的侧面设有定位螺栓。本实用新型主要用于凹槽内紧固螺栓的拆卸。

Description

一种凹槽内紧固螺栓的套丝工具
技术领域：本实用新型涉及一种螺栓套丝工具，特别涉及一种凹槽内紧固螺栓的套丝工具。
背景技术：设备的机械部件一般是用螺栓连接紧固在一起，经过很长时间，这些螺栓外露螺牙部份会出现锈蚀或其它原因的破坏，当设备检修或更换内部部件的时候，将这些螺牙用套丝扳牙重新回牙后当，才用将螺母从螺栓上旋下。其中部份设备的螺栓是在凹槽中的，用现有的套丝扳牙难以操作。
实用新型内容：本实用新型的目的是提供一种凹槽内紧固螺栓的套丝工具，主要解决现有套丝扳牙在凹槽内无法操作的技术问题。本实用新型的技术方案为：一种凹槽内紧固螺栓的套丝工具，为一只扳牙套座，扳牙套座外径小于凹槽直径，扳牙座套的内孔中装有套丝圆扳牙，扳牙套座上部为外六角帽，与套筒扳手的内六角相匹配。扳牙套座的侧面设有定位螺栓。本实用新型的有益效果是：本实用新型是一种凹槽内紧固螺栓拆装的过渡工具，用本实用新型可以很容易对凹槽内的紧固螺栓进行套丝回牙，并且本实用新型扳牙座套六角头部伸出凹槽，利用套筒扳手和接长杆就能很容易将凹槽内的紧固螺栓拆下。
附图说明：
附图为本实用新型应用结构示意图
图中：1.扳牙座套；2.圆扳牙；3.定位螺栓；4.接长杆；5.套筒扳手；6.凹槽螺栓；7.凹槽；8.外六角帽。
具体实施方式：
本实用新型配合附图说明如下：
圆扳牙2是市场上能买到的标准件，装在扳牙座套1的座孔中，由定位螺栓3顶在外圆的定位槽中，防止在套丝过程中，圆板牙2与座孔间发生相对径向位移。
实际操作中，凹槽螺栓6埋在凹槽7内，将圆扳牙2丝孔对准凹槽螺栓6的头部，扳牙座套1上部的外六角帽8装上常用的套筒扳手5，再用接长杆4接出，最后接上力矩扳手旋转进行套丝工作。
