The invention discloses a steel plate drilling machine with scrap recycling and fixing functions. According to the steel plate drilling machine, a first hydraulic cylinder drives a first hydraulic rod to drive a pressure plate to move downwards, so that a steel plate is extruded and fixed, the influence of movement of the steel plate in drilling on drilling effects and drilling accuracy is avoided, stability of a second hydraulic rod in the downward movement process is improved by the aid of a sliding sleeve, so that the drilling accuracy is further improved, water in a water storage tank enters a water outlet pipe by the aid of a first booster pump and is sprayed from a flushing sprayer, so that scraps generated by drilling the steel plate are flushed, cleanness of the surface of the steel plate is ensured, waste water generated by flushing the scraps falls into a water receiving funnel through a through hole, the waste water is collected by the water receiving funnel, environmental pollution caused by the waste water is avoided, the waste water entering a scrap recycling and drying box is filtered by the aid of a screen plate, the scraps are recycled, resources are saved, and practicability of the steel plate drilling machine is improved.
