The invention relates to the technical field of
mechanical equipment, and discloses a sheet
metal equidistant perforating device based on a
ratchet motion principle. The sheet
metal equidistant perforating device based on the
ratchet motion principle comprises a rack, a
workbench is fixedly connected to the inside of the rack, a fixing block is fixedly connected to the top of the
workbench, and asliding block is slidably connected to the inside of the rack; a lifting rod is fixedly connected to the bottom of the sliding block, a perforating motor is fixedly connected to the bottom of the lifting rod, a
drill bit is movably connected to the bottom of the perforating motor, a
ratchet bar is fixedly connected to the top of the sliding block, and a limiting pawl block is movably connected tothe top of the ratchet bar; through cooperation of the ratchet bar, the limiting pawl block, an adjusting pawl block, a connecting rod, a limiting ring and a movable pin, an effect of driving the ratchet bar to slide rightwards equidistantly is achieved, it is guaranteed that the rightward moving distances of the
drill bit are equal and hole distances among drilled holes are equal, the product quality is improved, therefore, the trouble that measurement and marking need to be carried out in advance is avoided, and the production efficiency of sheet
metal perforating is effectively improved.
