Abstract

The invention relates to the field of engineering, in particular to the strengthening and finishing machining of parts. The goal - improving the quality of processing and durability of deforming elements (DE). For this purpose, rings are placed in the tool body, which form an annular chamber with DE placed in it. In one of the rings of the chamber with respect to the circumference of the center of the DE with respect to the axis of the tool, holes are filled in, connected to the axial channel through which the working agent enters. The other ring is solid, rotatably mounted and connected to the rotational drive rotor. The rotor is made in the form of a plate pneumatic motor, the stator of which is connected to the tool body. The inlet of the pneumatic motor is connected by a radial channel to the axial channel of the housing. On the inner side of the ring there is a conical surface for contacting the cde. During the operation of the tool, compressed air enters the radial channels of the cylinder and the pneumatic motor through the axial channel of the housing, providing a circular movement of DE, pressing them to the conical surface of the ring, as well as rotating the latter from the pneumatic motor drive. Due to this, reliable multi-axis DE rotation is achieved. 1 hp f-ly, 3 ill. % (L fc E: o L ND

Description

The invention relates to mpcpopeHHiOj, in particular, to strengthening and finishing machining of parts with surface plastic flegDOpMUposanvieM,

The purpose of the invention is to improve the processing quality and durability of the deforming elements due to their reliable multi-axis rotation.

Figure 1 shows the instrument, the general id; in Fig.2 a section aa in Fig.1; on fig.Z. - section bb in figure 2

The proposed tool consists of a housing 1 on which rings are installed. 2 and 3. Their ends facing each other form an annular chamber 4 in which deforming elements 5 (balls) are placed. In case 1, an axial channel 6j is made which is connected by radial holes 7 to an annular chamber 4 and radial holes 8 with a cavity, formed by the ring 2 and the lid 9. In the wall of the ring 2 there are holes 10, which are open to the diameter of the center of the deforming element relative to the axis of the tool. The ring 3 is mounted with possible rotation on the needle ;; Iokashpiya ka: x 11 and its inner surface and made a conical surface 12 "With the ring 3, the rotor 13 of the pneumatic motor is made in one piece, the stator 14 is rigidly connected to the tool body 1 with textolite plates 15 installed in the radial grooves of the rotor 13. The aperture 16 (FIGS. 2 and 3) of the pneumatic motor is connected by channels 17 and 18 to the axial channel 6. The bore hole 19 is full through in the stator 14, the ring 2 assembled with the edge 9 is fixed by means of a nut 20 on the housing 1. The stator 14 is attached to the case 1 nut 21, Hole In the stator 14, it is made eccentrically with respect to the axis of the rotor mounting to ensure the operability of the pivtokokotor,

The offer -.tool works in the following way.

From the source is powered, and (not shown, the air is compressed to compress through the axial droplet 6 of housing 1 ,, holes 8 and then through holes 10 a ta, 1 s; in hole 7 7 - into the ring tag 4, while the flow of compressed air from holes 10 provides circular movement of the deformed element. The element EE 5 along the annular chamber 4 and bites

them to the conical surface 12 of the ring 3. The compressed air flow from the radial holes 7 provides an additional force effect of the deforming elements 5 to the surface being treated. Simultaneously, compressed from the axial channel 6 through the channels 18 and 17 enters the inlet 16 of the pneumatic motor, which causes the rotor 13 to rotate. Since the rotor 13 is made integral with the ring 35, the latter is also rotated. As a result of the contact of the deforming elements 5 with the conical surface 12 of the rotating ring 3, as well as exposure to flows of cool air supplied from

holes 7 and 10, provides reliable multi-axis rotation deformed. Juishch. elements 5, which leads to an increase in the resistance of the latter while ensuring the workpiece surface is uniformly peeled; in addition, the contact of the deforming elements 5 with the conical surface 12 of the ring 3 EXCLUDES the axial movements of the deforming elements 5, which reduces the waviness of the treated surface.

The proposed device allows improving the quality of processing by reducing the waviness of the treated

change it when finishing. In addition, the resistance of the deforming elements is enhanced by ensuring their proper multi-axis rotation while maintaining uniform surface hardening of the hole,

& o rmulare of the invention 1, HHCTpytvieHT for strengthening and processing of the internal cylindrical surfaces, containing a box body in which two rings of annular chambers are disposed: there are deformed elements perceived by the working the agent supplied through the holes connected to the axial channel, is made - -; in one of the rings of the chamber with respect to the circumference of the chain of the deforming element relative to the tool axis, as well as the radial holes in the housing, which is different in order to improve the quality of processing and durability of the deforming elements: due to their reliable MULTI-CORRECT rotation, the tool is equipped with a rotation drive

the second ring, the second ring being solid and on its inner surface there is a conic surface for contacting with deforming elements,

2. The tool according to claim 1, characterized in that the rotational drive

The second ring is filled in the form of a plastic pneumatic motor, the rotor of which is connected to the ring, and the stator - to the tool case, and the air inlet of the pneumatic motor is connected by a radial channel to the axial channel of the body.
