我厂高频淬火机床为TX_1型,淬火定位夹具为“宝塔轮”式。这种夹具操作麻烦、费时间,而且齿轮内孔与圆台配合间隙较大时,齿轮与感应器容易相碰,易损坏感应器或工件。为解决上述问题,我们制作了如图1的顶尖定位夹具,其工作状态如图2。该顶尖夹具的优点是:便于制造,齿轮转动时摆差小、加热均匀,定位快,提高了工作效率,通 Our factory for high-frequency quenching machine TX_1-type, quenching positioning fixture for the “pagoda wheel” type. This jig operation troublesome, time-consuming, and the gear hole and the round table with a larger gap, the gear and the sensor easy to meet, easy to damage the sensor or workpiece. In order to solve the above problem, we made a top positioning fixture as shown in Figure 1, and its working status is shown in FIG. 2. The advantages of the top fixture are: easy to manufacture, small swing when the gear rotation, uniform heating, fast positioning, improve work efficiency, through
