The invention relates to mechanical engineering and can be used to strip edges, e.g. pipes and shafts.

The object of the invention is to increase productivity by increasing tool life, as well as by making fuller use of its cutting surface. . ,

Fig. 1 shows a device for deburring from the outer edge of a cylindrical surface; figure 2 is a section aa in figure 1; Fig. 3 shows a device for deburring from the inner edge of a cylindrical surface; figure 4 - section bB in figure 3,

A device for stripping the edges of a cylindrical surface consists of a working body made in the form of a collet 1, in the shank of which a running nut 2 is rigidly fixed, through which a lead screw 3 with a spring 4 mounted on it passes. The lead screw 3 is fixedly mounted in the holder 5. On the collet 1 fixed cutting elements in the form of plates b, interacting with part 7.

The device operates as follows. : ...-:

Using a drive (not shown), the collet 1 is brought to the part 7, When the part interacts with the cutting plates 6 due to

 the friction forces and the elasticity of the elements of the collet, the spring 4 is compressed. In this case, the lead screw 3, interacting with the lead nut 2, turns the collet 1 relative to the axis of the part. With further compression of springs 4, its stiffness increases and overcomes the friction and elasticity of the ale

collet chutes, which moves along part 7. Thus, during a full working stroke, a constant rotational and translational movement of the collet 1 occurs. When the tool is retracted, the process occurs in the reverse order,.

Thus, due to only the reciprocating movement of the tool, the rotational-translational movement of the collet takes place, the entire working surface of the cutting inserts is used, which increases their service life. In addition, the need for only reciprocating movement of the tool allows the use of simpler and more reliable drives and thereby expand the technological capabilities of the device. ; ;
