在钻削盲孔和攻丝盲孔以及特殊要求孔深、攻丝深度的情况下,由于不能直接观察加工孔的深度是否达到了深度要求,而需要反复测量(试攻),这不但费时费事,且稍一疏忽,深度就会过大,致使工件报废。为此,我们采取了如下措施,有效地控制了钻孔、攻丝的深度。一、控制钻孔深度的方法对于钻孔深度的控制,可以采用下述方法。如图1所示,在钻头1上增加一个控制孔深用的限位圈2,其位置1根据工件孔的要求深度确定,并用螺栓3加以固紧。用本方法进行钻孔时,不用担心孔深1尺寸的大小。当钻
In the case of drilling blind holes and tapping blind holes and the special requirements of hole depth and tapping depth, it is not only time-consuming and complicated to perform measurement (trial and error) because it is not possible to directly observe whether the depth of the hole has reached the depth requirement or not. , And a little negligence, the depth will be too large, resulting in scrapped parts. To this end, we have taken the following measures to effectively control the drilling, tapping the depth. First, the method of controlling the depth of drilling For drilling depth control, you can use the following method. As shown in FIG. 1, a limit ring 2 for controlling the depth of the hole is added to the drill bit 1, and its position 1 is determined according to the required depth of the workpiece hole and fastened with the bolt 3. Drilling with this method, do not worry about the size of the hole depth 1 size. When drilling
