Abstract
Изобретение относитс к оборудованию дл строительства магистральных трубопроводов , а именно к устройствам дл сн ти внутреннего грата на кольцевых стыках труб, сваренных, например, контактной сваркой. Целью изобретени вл етс повышение качества обработки путем обеспечени равномерного внутреннего усили шва по всей поверхности стыка. Устройство фиксируетс в полости трубы. В полость В гидроцилиндра 16 подаетс рабоча жидкость , в результате чего последний совершает перемещение по штоку 17 относительно поршн 20. Вместе с гидроцилиндром 16 перемещаетс и корпус 14 с резцовой головкой, установленный на гидроцилиндре посредством подшипника 15. При контакте опорных шариков резцедержателей с коническим участком 18 штока 17 резцедержатели получают радиальную подачу и занимают рабочее положение, на которое были выставлены при настройке. При дальнейшем совершении осевой подачи резцы вступают в контакт с гратом и осуществл ют срезание его. Вращение корпуса 14 осуществл етс посредством привода 21. Затем давление подаетс в полость Б гидроцилиндра 16, и резцова головка возвращаетс в исходное положение. 3 ил. со сThe invention relates to equipment for the construction of trunk pipelines, namely, devices for removing internal burrs at annular joints of pipes welded, for example, by resistance welding. The aim of the invention is to improve the quality of processing by providing a uniform internal seam force over the entire interface surface. The device is fixed in the cavity of the pipe. The working fluid is supplied to the cavity B of the hydraulic cylinder 16, as a result of which the latter moves along the rod 17 relative to the piston 20. Together with the hydraulic cylinder 16, the housing 14 with the cutting head mounted on the hydraulic cylinder by means of the bearing 15 also moves. the rod 17 toolholders receive a radial feed and occupy the working position to which they were set during adjustment. Upon further completion of the axial feed, the cutters come in contact with the burr and cut it off. The rotation of the housing 14 is carried out by means of the actuator 21. Then the pressure is supplied to the cavity B of the hydraulic cylinder 16, and the cutting head returns to its original position. 3 il. with s
