The invention provides an insulating rubber pad abutment cutting machine, and belongs to the technical field of power construction appliances. The insulating rubber pad abutment cutting machine comprises a frame and a cutting mechanism, material feeding and discharging openings are arranged at two sides of the frame, and the machine further comprises two layers of cutting tables for cutting insulating rubber pads, pressing mechanisms arranged on the tops of the cutting tables and used for pressing and positioning the insulating rubber pads, dust removing mechanisms arranged at the upper part of the frame and used for sucking insulating rubber pad chippings, and a control system for controlling the cutting mechanisms, the pressing mechanisms and the dust removing mechanisms. The insulatingrubber pad abutment cutting machine automatically cut two insulating rubber pads by the two layers of cutting tables on the frame through controlling cutting parameters by the control system, so the machine has the advantages of straight cutting, no gaps or burrs during abutment, and improvement of the cutting work efficiency of the insulating rubber pads.
