MACHINE-TOOL FOR THE ABRASIVE PROCESSING OF PIPE ENDS Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: machine-tool is used in the technological equipment for polishing the pipeline ends for pneumatic and hydraulic systems in planes and other machines. The machine-tool for the pipe polishing has housing 1, finger 12 for the pipe fixation along the inner diameter and an instrumental head with the receptacle for the current supply. The instrumental head is set up in guides 4 of the rolling motion for the displacement in the radial direction from the electromechanism of the translation feed with self-braking through the electrocontact force transducer made in the form of spring 10 with pusher 7 acting on microswitch 11. Self-braking screw gear 8 presses the polishing wheel against pipe 13 with the aid of spring 10 with the preset force during the whole polishing process. EFFECT: ensured stability of the processing conditions and enhanced quality. 1 dwg
