我们在万能铣床上增加一个液压自动分度头附件,用之代替普通分度头来加工各种轴类花键,减少了加工辅助时间,较大的提高了工效。其工作原理如下(见下图): 当双向液压油缸右边进油时,工作柱塞由右端运动到左端,由于工作柱塞上铣有齿条,则柱塞的运动必然带动与齿条相啮合的转动齿轮顺时针方向旋转一定的角度。转动齿轮内孔套在棘轮上,可在棘轮上游动,在转动齿轮上固定有棘爪,所以当转动齿轮顺时针转动一定角度时,棘爪拨动棘轮,使棘轮也顺时针转动同一角度。而棘轮是固定在分度
We are in universal milling machine to add a hydraulic automatic indexing head accessories, instead of the ordinary indexing head to process a variety of shaft spline, reducing the auxiliary processing time, a greater increase in work efficiency. The working principle is as follows (see below): When the two-way hydraulic cylinder right into the oil, the work of the plunger from the right end of the movement to the left, as the work of the plunger milling rack, the plunger movement will inevitably drive with the rack engagement The rotating gear rotates clockwise a certain angle. The inner hole of the rotating gear is sheathed on the ratchet and can move upstream of the ratchet. A pawl is fixed on the rotating gear, so when the rotating gear rotates clockwise by a certain angle, the pawl pushes the ratchet to make the ratchet rotate clockwise by the same angle . The ratchet is fixed in the indexing
