FIG i

The invention relates to a non-abrasive finishing of parts, in particular, to pritiram.

The purpose of the invention is to increase the longevity.

Figure 1 shows the tool section; in fig. 2 - top view tool; on fig.Z - the process of replacing faces with different direction grooves; Fig. 4 shows a variant of an inlay with gaskets between rows of shape-forming elements; figure 5 is a variant of the cutting edges of the tool; figb is another variant of the cutting edges of the tool; figure 7 is a tool, top view with hollow work items; FIG. 3 shows a variant of the arrangement of the cutting edges of the tool from a set of hollow work items; Fig. 9 shows another alternative arrangement of the cutting edges of the tool from the set of hollow work pieces.

The lap contains a housing in the form of a collapsible frame 1 with an internal groove 2, into which the working surface elements are installed in the form of identical cubes 3 with a through hole, rotated on rods 4, while the free ends of rods 4 are installed in the indicated groove 2 frames 1. On the faces without holes of the cubes 3 there are grooves 5 forming the cutting edges in a different direction. The joints of the connectors of the frame 1 are located in a convenient place for its disassembly and are connected with the help of the strip b and screws 7. Spacers 8 can be placed between the rows of forming elements to protect the cutting edges. The elements of the working surface can be made in the form of identical hollow parallelepipeds 3 with a height that is a multiple of their width with grooves 5 on the end, forming a cutting edge ikll in a different direction.

Working with priter is carried out as follows.

The tool is formed by undocking the collapsible frame 1, pushing the rods 4 apart in the slots 2 and turning them into the desired position of the cubes 3. with grooves 5. If necessary, a different arrangement of the tool grooves 5 is ensured due to their interchangeability without applying the location of the cubes 3. To ensure the damage of the cutting edges of the closed cubes 3 between them can be set Laying 8, Such a tool from disassembled cutting edges facilitates its sharpening.

The use of the tool allows to obtain a working surface of various types for finishing the details at its quick change and ease of sharpening and to increase its durability.

Claims (1)

Invention Formula 1, Priter, made in the form of a case and working elements installed in it, characterized in that, in order to increase the pruning length of the pruning, the case is made in the form of a frame with grooves, and the priter is provided with rods installed in said grooves and mounted on said rods with the possibility of rotation and fixation, while grooves are made on the faces of the working elements, 2, the lap according to claim 1, characterized in that the grooves on the edges of the elements are made multidirectional. . 3, lap according to claim 1, characterized in that the work elements are hollow.
