ABOUT

Ate 2 The invention relates to the application of coatings by means of mechanical rubbing with a tool from a coating material to provide details of friction units of extreme pressure and antifriction properties. A device for frictional-mechanical coating is known, comprising a housing with a spring-loaded plunger E installed therein, in which a rubbing element and a feed screw with a pusher l are located. The device does not allow intermittent surfaces to be machined, since the tool is cut by the edges of the holes located on the machined plane. It is also known device for. The coating contains a housing with a spring-loaded plunger installed on it, in which an ellipsoidal roller 2 tool is installed in the hinged sleeve. Due to the large extent of the tool-to-part contact area, the device allows you to process discontinuous surfaces, but not both layer of the part, which reduces the quality of coatings. - A device for freaks is known: -; snoz. -Akhanicheskoe coating, comprising a housing with a sub :: ::: pin gland, an adjusting screw with a nut, pressure rollers and a tool made of applied material. The device provides an automatic tool feeding and plastic deformation by the surface-feed roller {3J. However, this device is characterized by the impossibility of processing discontinuous surfaces due to cutting the tool with the edge of the hole. The aim of the invention is to improve the processing performance of discontinuous surfaces. A single goal is achieved by a TIM that the device for frictionally mechanical coating, comprising a housing with a spring-loaded plunger, an adjusting screw with a nut, pressure rollers and a tool made of an applied material, is provided with a base, a lever and supports for pressure rollers, with the base and the lever pivotally connected to the housing and mounted with the possibility of interaction with each other, and the tool made of applied material SG is mounted on the adjusting screw with the NEW 1ozhnostyu movement relative thereto, FIG. 1 shows the device, a general VIEW} in FIG. 2 - the same in terms of. The device comprises a housing 1 with rollers 4 and 5 disposed on supports 2 and 3, which can freely rotate on axles b and 7. The adjusting screw 8 is freely located on the rollers 4 and 5. The adjusting screw is equipped with tool 9 of the coating material, plunger 10, spring 11, sleeve 12, nut 13 and lock nut 14. Sleeve 12 has an annular groove in which roller 5 is inserted. The adjusting screw 8 has a collar 15 in which the inner end of the plunger 10 rests. which through the pusher 17 loads mounted on the hinge e 18 lever 19. The lever 19 abuts against the base 20, on which a hinge 21 is secured poyuschyu apparatus body 1, apparatus operates as follows. The device base 20 is mounted on a transverse support of a lathe (not shown), instead of the toolholder, so that the axis of the adjusting screw 8 is with the spindle axis angle L 60-80 (Fig. 2). The adjusting screw 8 is fastened tightly, and by rotating the nut 13, the spring 11 is compressed to the necessary force for rubbing the coating. The nut 13 is secured with a lock nut 14. Next, the tool 9, for example made of brass, is put on the adjusting screw 8 and the screw is placed on the rollers 4 and 5 so that the rollers 5 fit into the ring groove of the sleeve 12. The spring 16 must ensure that the adjusting screw 8 is pressed to the work piece 22 with a pressure sufficient to plastic deform the surface layer of the part. By moving the transverse caliper the tool 9 and the adjusting screw 8 are brought into contact with the workpiece 22. The tool 9 depresses the spring 11 and loads it, and the housing 1 rotates on the hinge 21, the lever 19 also rotates and loads the prune 16, respectively. The surface of the sheet 22 applies a working fluid, such as glycerin, the parts give rotation, and the caliper is longitudinal and is processed. In the course of processing due to the friction surface — parts 22, the rotation of the tool 9 and the adjusting screw 8 takes place. The proposed device allows the coating to be applied to the surface being processed and at the same time

make its hardening due to friction on the adjusting screw, which is made of high-strength steel or hard alloy. The device also allows machining of surfaces with different holes and grooves, since the tool contacts the part in the form, which has a sufficiently large extent and can block large holes. The design of the tool provides ease of replacement, which reduces the time it takes to replace it. And setup. The tool feed is carried out by moving the cross support of the machine.

With this interposition of the rubbing and smoothing tools. anti-friction cops for

The friction count during machining is transferred from the part to the tool that is used to smooth out (adjusting screw), cover it and protect it from wear. Smoothing a part reduces its surface roughness, increases fatigue strength, microhardness, thereby increasing its reliability and durability,

0 Compared with the basic object, the present invention allows to reduce the time spent on reinstalling the tool, hardening the surface layer of the part, while ensuring a high wear resistance of the smoothing tool. The expected economic effect from the use of the invention is about 21 thousand rubles per year.
