Abstract

Устройство для обработки поверхности, содержащее рабочие инструменты - долота, закрепленные подвижно в шахматном порядке, воспринимающие ударный импульс с возможностью возврата в исходное положение при помощи пружин, рабочие инструменты расположены на закрепленном на корпусе роторе отличающийся тем, рабочие органы выполнены в виде стержней со сменными наконечниками и имеющие в противоположном конце головку с парой подшипников скольжения, установлены радиально в один ряд в отверстиях полого неподвижного цилиндра и прикрепленного к нему короба и удерживаются в исходном положении пружинами, работающими на растяжение, внутри цилиндра соосно, на подшипниках расположен вал, на котором установлены и неподвижно закреплены попарно спаренные диски, на поверхности которых закреплены дуги, наружные концы каждой пары дуг завершаются на обрезе диска, а внутренние концы дуг направлены в сторону центра диска, при вращении вала с дисками дуги наружными концами попарно подходят к головкам стержней с подшипниками скольжения, подхватывая их по мере вращения диска и растягивая пружину, перемещают к центру диска по направляющим, по достижении конца дуг стержни под действием пружины и собственной массы срываются с направляющих (совершают рабочий ход) и ударяются рабочим концом об обрабатываемую поверхность, сила удара регулируется количеством рабочих витков пружины и изменением массы сменных наконечников, попарный сдвиг дуг по фазе чередует рабочий ход стержней по фронту обработки, изменение числа дуг на дисках увеличивает или уменьшает количество воздействий стержней на обрабатываемую поверхность за один оборот д�A surface treatment device containing working tools — staggered bits movably staggered, receiving a shock pulse with the possibility of returning to the initial position by means of springs, working tools located on a rotor fixed to the housing, characterized in that the working bodies are made in the form of rods with interchangeable tips and having at the opposite end a head with a pair of plain bearings, are mounted radially in the same row in the holes of the hollow stationary cylinder and attached to mu of the box and held in the initial position by springs operating in tension, coaxially inside the cylinder, a shaft is located on the bearings, on which pairwise paired discs are mounted and fixedly fixed, on the surface of which arcs are fixed, the outer ends of each pair of arcs end on the edge of the disc, and the inner the ends of the arcs are directed toward the center of the disk, while rotating the shaft with the arc disks, the outer ends pairwise approach the heads of the rods with sliding bearings, picking them up as the disk rotates and stretching the springs y, move to the center of the disk along the guides, upon reaching the end of the arcs, the rods under the action of the spring and their own mass break off the guides (make a working stroke) and hit the working end against the work surface, the impact force is controlled by the number of working turns of the spring and the change in mass of interchangeable tips, pairwise phase shift of the arcs alternates the working stroke of the rods along the machining front, changing the number of arcs on the disks increases or decreases the number of impacts of the rods on the surface to be machined in one revolution
