Description
技术领域 technical field
本发明涉及一种机床工具，具体涉及一种钻孔兼倒角机构。 The invention relates to a machine tool, in particular to a drilling and chamfering mechanism.
背景技术 Background technique
随着我国经济持续增长，工业水平不断提高，机械制造行业发展极为迅猛，钻孔加工是机械加工中重要的组成部分。用钻头在金属或工程材料上加工各种螺纹底孔、通孔和盲孔等称之为钻孔。钻孔时，一般情况下，钻头应同时完成两个运动；主运动，即钻头绕轴线的旋转运动（切削运动）；辅助运动，即钻头沿着轴线方向对着工件的直线运动（进给运动）。在钻孔以后，根据后续的加工或装配等加工工艺要求，还需要对该孔进行倒角加工，尤其在大批量生产，较多孔的工件中，浪费了大量的时间，机械加工非常讲究效率，是需要尽量避免的。 With the continuous growth of my country's economy and the continuous improvement of the industrial level, the machinery manufacturing industry has developed extremely rapidly, and drilling processing is an important part of mechanical processing. Using a drill to process various threaded bottom holes, through holes and blind holes on metal or engineering materials is called drilling. When drilling, in general, the drill bit should complete two movements at the same time; the main movement, that is, the rotational movement of the drill bit around the axis (cutting movement); the auxiliary movement , that is, the linear movement of the drill bit toward the workpiece along the axis direction (feed movement). ). After drilling, the hole needs to be chamfered according to the subsequent processing or assembly process requirements, especially in mass production and more porous workpieces, a lot of time is wasted, and machining is very efficient. is to be avoided as much as possible.
目前，在数控技术高度发达的今天，生产企业采用的钻孔倒角的方式效率仍然不高。在钻孔完成后，拆除钻头，安装倒角刀后按照孔数目逐个倒角，在数控铣床或加工中心上，需要把钻孔程序重新运行一遍。调整极为不便，影响了加工效率，造成了生产成本的提高。 At present, in today's highly developed numerical control technology, the efficiency of drilling and chamfering adopted by manufacturers is still not high. After the drilling is completed, remove the drill bit, install the chamfering tool and chamfer one by one according to the number of holes. On the CNC milling machine or machining center, the drilling program needs to be run again. The adjustment is extremely inconvenient, which affects the processing efficiency and increases the production cost.
