我厂在精磨油泵齿轮(如图1)的内孔时,采用了一种专用夹具,不但可以保证齿轮内孔与端面的垂直度,而且能使内孔与节圆同心,工件的装卡也非常方便。使用后的结果很满意。现在将这种夹具的结构及用法介绍在下面,供大家参考。夹具的结构如图2。夹具体1直接安装在机床的花盘上:平面A是用作齿轮端面定位的,应在装到机床的花盘上后磨出,这样可以保证平面A与机床主轴的垂直度。夹具体的大小根据齿轮的直径,宽度和模数等来决定。在夹具体1的壁上,开有三个等分的槽子。在每个槽子内装入一个钢球5。为
I plant in the grinding oil pump gear (Figure 1) of the hole, the use of a special fixture, not only to ensure that the gear bore and end face of the verticality, but also make the inner hole concentric with the pitch circle, the workpiece loading Also very convenient. After using the result is very satisfied. Now the structure and usage of this fixture is introduced below, for your reference. Fixture structure shown in Figure 2. Clamping body 1 is mounted directly on the faceplate of the machine: Plane A is used for positioning the end face of the gear and should be ground off after being fitted to the faceplate of the machine so that the plane A is perpendicular to the machine spindle. The specific size of the clamp depends on the diameter, width and modulus of the gear. On the wall of the clamp body 1 there are three equally spaced slots. Install a steel ball 5 in each groove. for
