The invention relates to mechanical engineering, in particular, to a cutting tool for processing curved surfaces of parts ab gas 1G11YU.i material-, 1m.

The purpose of the invention is to expand the technological capabilities to provide processing of curvilinear windows.

FIG. 1 shows a device, an exploded view to a section; in fig. 2 - view. in fig. one.

The device for abrasive machining of upper surfaces consists of (npidel, corrrv ca 2 and working e, 1st element 3. The working element 3 is made in the form of a helix 4 of elastic lept, one end of it is fixed on the bushing. 1, and the second on the body 2, out of 1 in the form and set-up bottom 5 on pshindo / L I with the possibility of (ziksirovapnogo autumn non-: remeits pi i; i OBO) OTa.

On the qi, the first part of the body 2 have holes 9 for supplying abrasive body inside the body, which during rotation wakes up in the inter-turn gap of the helix slit on the processing surface. The winding of helix 4 is made in the direction of rotation of pindel 1, which ensures a constant movement of the abrasive material from the periphery to the wrench axis of the processed top surface.

The axial displacement and rotation of the housing 2 relative to I; I 1 requires the formation of the profile of the working part and the transfer of the necessary network to it by changing the inter-turn gap of the helix 3 by twisting the coils around the open position by fixing its position.

The working element is fixed separately from block 1 by a nut 6, i.e. the fixed position of the body 2 is fixed, and the uniform formation of the profile of the working part according to iiepn (|) epi is made by adjusting rods 7. concentrically located in the rotating sleeves 8 on the bottom of the casing 5. The number of tons of g is selected depending on the size (diameter) of the working part, the number of its indentations, the thickness of the tape of the helix 3 and its rigidity. So, for example), with Ma.; :) ix diameters of the working part, the need to use

Vanilla t to form its profile disappears.

The proposed technical solution does not exclude the possibility of scraping: 1 turns in the process of forming a profile that can be achieved by turning the body 2 relative to 1 pin 1 until the turns are fully tightened and squeezed between themselves and when passing through other intermediate abrasives or ({ zriktspopnyh. materiya. Yuv.

The rigs 7 are located concentrically on the bottom of the housing 5 in the rotating sleeves 8 and are connected to the turns of the helix by means of known reels (in Fig. 1 the connection of the wires to the helix of the helix is shown). The sleeves 8 are made rotatable and are coupled with the thrust 7 of the threaded connection for carrying out the sigher movement of the pull rod as they rotate.

The profile of the working part of the device is formed by turning the body 2 relative to the spindle 1, as a result of which it axially moves along the threaded part by the amount of the cavity or bump of the machined surface and is fixed on the spindle 1 with the nut 6 and the end screws. The adjustment of the profile of the working part to the required curvature is carried out by the adjusting rods 7 by rotating the sleeves 8. The formation of the concave surface is carried out similarly to the convex.

In the device, as an abrasive material, you can use an abrasive cheek in the form of a tape filled into a spiral gap between the coils and clamped directly by the coils of the working part by turning the body 2 relative to the pin 1.

The proposed design of the device allows forming a working surface of different radius of curvature, both convex and concave, which ensures its durability and versatility in operation and eliminates the variety of devices and their readjustment for processing surfaces of various shapes and curvatures.
