The invention discloses a
water circulation device of a multi-spindle drilling
machine. The
water circulation device of the multi-spindle drilling
machine comprises a
water storage pool, wherein a first support is fixedly connected with one side of the upper end of the
water storage pool, an adjusting frame is fixedly connected with the top end of the first support, a first rotating shaft is rotatably connected with one side of the adjusting frame, a telescopic rod is slidingly connected with the same side, where the first rotating shaft is located, of the adjusting frame, a water pump support is fixedly connected with the top of the
water storage pool, a water pump is fixedly connected with one end of the water pump support, and a water suction
pipe is fixedly connected with two ends of the water pump. According to the
water circulation device of the multi-spindle drilling
machine, by arranging filtering screens, water valves, second rotating shafts and fans and by forming dust storage grooves, impurities in cooling water in the water suction
pipe are removed, the number of times of water circulation is increased correspondingly, the water suction
pipe is prevented from being blocked, a
water cooling effect of a cooling frame on a working frame is guaranteed, and due to rotation of the fans, an
air cooling effect is achieved, so that damage caused by high temperatures to the device is avoided.
