Description

II

Изобретение относитс к машиностроению .The invention relates to mechanical engineering.

Известно устройство дл удалени внутреннего грата, содержащее штангу с приводным валом, несущим рабочий орган с ограничивающими элементами и опорные ролики .A device for removing internal burr is known, comprising a rod with a drive shaft carrying a working member with limiting elements and support rollers.

Недоцтатком этого устройства вл етс низка производительность и неодинакова по периметру шероховатость поверхности.The disadvantage of this device is low productivity and uneven surface roughness around the perimeter.

Цель изобретени - повышение производительности обработки грата,улучшение качества обрабатываемой поверхности и увеличение технологических возможностей устройства.The purpose of the invention is to increase the processing performance of deburring, improve the quality of the surface being treated and increase the technological capabilities of the device.

Поставленна цель достигает : тем, что устройство снабжено торсионными валами и кулачками, а опорные ролики установлены на кулачках с возможностью принудительного перемещени рабочего органа в зону обработки.The goal is achieved: in that the device is equipped with torsion shafts and cams, and the support rollers are mounted on cams with the possibility of forced movement of the working member to the machining zone.

Claims

For convenience of assembly and in order to increase the range of applicability, the housing 1 can be made of at least two parts that are connected using an adapter 11. The device includes a bracket 12c with a support surface 13 and a handle 14. The device operates as follows. An actuator is mounted on the bracket 12 of the housing 1 (it is possible to use a pneumatic or electric drill 7 and connect to the free end of the drive shaft

2. The device, pre-assembled in such a way that the size from the supporting surface 13 of the housing 1 to the middle of the milling cutter 4 is equal to the size from the beginning of the pipe and the seam (control on the measuring scale is possible), is inserted into the drive against the stop It is brought to the stop in a bur. The drive is turned on, and the milling cutter 4 cuts into the bur by means of the pressing mechanism up to the stop of the limiting rollers 3 into the inner wall of the pipe being processed. After that, all 4 the device is rotated around the longitudinal axis on the handle 14, Thus, this device provides high performance and good quality of the processed surface. Invention A device for removing internal burr, comprising a rod with a drive shaft carrying a working member with limiting elements and support rollers, characterized in that, in order to improve the quality of processing, the device is equipped with torsion shafts and cams, and move the working body to the treatment area.
