Large rectangular water stop groove machining method and gate groove seat ring of tail water emergency gate
The invention discloses a large rectangular water stop groove machining method and a gate groove seat ring of a tail water emergency gate. The large rectangular water stop groove machining method comprises the following steps that firstly, a three-edge milling cutter of phi 16.5mm is selected and clamped on a milling machine through a clamp tool; secondly, after clamping is completed, a water stop groove of a workpiece is machined through the milling machine, the cutter is fed by 2mm every time, and five circles are milled, so that the depth of the groove reaches 10mm; thirdly, a three-edge milling cutter of phi 17.5mm is selected to replace the three-edge milling cutter of phi 16.5mm originally located on the clamp tool of the milling machine, and cutter changing machining is conducted; and finally, after cutter changing is completed, the center line of the three-edge milling cutter is aligned with the center line of the water stop groove, the water stop groove is milled by one circle again, the depth and the width are increased, when the three-edge milling cutter of phi 17.5mm is adopted for machining the water stop groove, complete and continuous machining is needed, and the milling machine cannot be stopped in the midway. The machining method has the beneficial effect of being high in machining size precision, and then the sealing effect of the gate groove seat ring of the tail water emergency gate is improved.
本发明公开了一种大型矩形止水槽加工方法及尾水事故闸门门槽座圈，其中大型矩形止水槽加工方法包括以下步骤：首先选用φ16.5mm的三刃铣刀，采用夹具工装将三刃铣刀装夹于铣床上；其次在完成装夹后，通过铣床对工件的止水槽进行加工，每次进刀2mm，铣完5圈，使得槽的深度到达10mm；然后选用φ17.5mm的三刃铣刀，替换原本处于铣床的夹具工装上的φ16.5mm的三刃铣刀，进行换刀加工；最后在完成换刀后，将三刃铣刀的中心线对准止水槽中心线，对止水槽再铣一圈，扩深扩宽，且采用φ17.5mm的三刃铣刀对止水槽进行加工时，需完整连续的加工，中途铣床不能停机。本发明公开的加工方法具有加工尺寸精度高的优点，进而使得尾水事故闸门门槽座圈的密封效果提高。
