    The invention relates to the field of engineering, in particular to devices for assembling shoe brakes. A device for connecting friction linings with a brake pad is known, comprising a hoop covering the linings, a box with a two-sided eccentric in the center of the hoop, interacting with spring-loaded and oppositely arranged with respect to each other brushes, brake pads and linings, an elastic band installed on the inner side of the hoop opposite each segment through a layer of thermal grease, which has inwardly directed bends and ends at both edges rigidly associated with the hoop, the heating device and the jig with tape 1. The disadvantage of the known device is the complexity of construction and high manufacturing cost. The aim of the invention is to reduce the cost of manufacture. This is achieved due to the fact that in the device for gluing the friction linings to the brake shoe containing the heating device and clamping device, the heating device is made in the form of a spiral inductor, in the latter the direction for the fixture is made, and the axis of the inductor is located under angle of 90 ° to the plane of the jig. In this case, the radial clearance between the clamping fixture at the installation site of the pads and the inductor is constant, and the spiral inductor has at least one circular coil located opposite to the location of the brake pads in the inductor. In addition, the inductor is made in the form of a copper tube wound in a spiral, wherein the turn coil is larger than the diameter of the tube, and the guides are made in the form of a tube of electrically insulating material in which the inductor is installed. The clamping tape is made of electrically insulating material and contains natural or synthetic fibers. FIG. 1 shows a device for gluing friction linings; in fig. 2 is a section A-A in FIG. I; in fig. 3 — heating; gfs / ijiioe device; -1 the same, top view. A device for gluing friction lining to the brake shoe contains a clamping device 1 and a heating device consisting of a spiral inductor 2 located in the pipe 3 of electrically insulating material. Spiral inductor 2. in which naravl junda 4 for clamp I is arranged in such a way that its axis forms a 90 ° angle with the plane of clamping device 1, and is connected to the high-frequency current source 5. Spiral inductor 2 and at least At least one circular coil 6, reshaping at the opposite location in the inductor brake pads 7 and 8, the horses of which are electrically connected and isolated from other elements. Inductor 2 may have a different design implementation. In particular, any means can be used to feed the clamping devices to the inductor, to guide them inside the inductor and to remove them from the inductor. The nanrimer guides 4 can be made in the form of rods parallel to the axis of the inductor 2, interacting with the corresponding holes in the jigs 1. The rods can be pulled out of the electrolysis material material, can also withstand a high temperature and have a small coefficient of friction, for example from glass. Inductor 2 may be horizontally distributed. However, the clap may be curved, and its cross section may be changed depending on the size or size of the tool 1. Clamping pattern i includes an infinite ring 9 that forms the outer shell of the clamp devices 1 and covering plates 10 and 11, preliminarily covered with a layer of thermosetting adhesive, for example, based on phenol, formaldehyde resin or butadiene. The endless tape 9 is made of high-strength electrically insulating material, which withstands high temperatures and consists at least in part of natural or synthetic waves (like Kevlar. In addition, clamping device 1 included in the clamping device 1, exchanged between brake pads 7 and 8 and pressing them against the pads 10 and 11. Preload pads 7 and 8 with any type of thermosetting coating in order to protect them from oxidation after installation in the brake. The structure also includes V-shaped electrically conductive elements 12 and 13, which interact mechanically and are in electrical contact with the ends of the pads 7 and 8, forming with the latter electrically conductive turns marked with lines 14 and 15, and the compression unit located between the bases V-shaped elements 12 and 13 and consisting of opposing plates 16 and 17, between which are pre-compressed springs 18, expanding them. N, lozenges 16 and 17 are held in a certain position with a wedge 19 placed between two telescopically .Im details 20 and 21, s One with plates. 16 and 17, respectively, on which there are pins 22 and 23 placed inside the electrical insulating sleeves 24 and 25, mounted in the shape of elements 12 and 13. Between the end surfaces of the plates 16 and 17 and V- figurative ale. electrically insulating rings 26 and 27 were installed. The synthetic material “Saloron. V-shaped elements 12 and 13 can be made of any electrically conductive material, aluminum, copper or, respectively, their alloys. A device may have a different design, for example, it may contain an endless belt 9 associated with 1P-1M. In this case, the adjacent ends of the pads 7 and 8. Can be electrically connected either directly or through two electrically conductive elements, equivalent to elements 2 and 13, which, together with the coupling box 7 and 8, are electrically isolated from the clamping device and form one electrically conductive coil similar to the coils marked lines 14 and 15. / 1, in order to assemble the clamping device 1 with the pads 7 and 8 and the pads 10 and 11, compress the spring 18 so that the belt 9 can be put on (compression of the springs 18 determines force, effect on nakla; 1ki 10 and 1 and pads 7 and 8). Then the clamping device 1 stops the wedge.m 19, which com- pens any deviations from the normal size. The clamping device can also be used for one brake shoe 7 or 8. In this case, the ends of the shoe are electrically connected by an electrically conductive element 12 or 13 electrically insulated from the rest of the component 1. Such clamping devices can be applied for 1 sec. Ktop 2para.mi. To transport the clamping devices 1, there is a conveyor 28 with a cooling device 29 and a conveyor belt 30 devices to the inductor 2. When the clamping device 1 is exchanged inside the inductor 2, the brake pads 7 and 8 are uniformly heated at the expense of limiting the area of heating. pads 7 and 8. The pads are heated simultaneously by eddy currents and due to the transformer connection formed between the winding of the inductor 2 and the coils marked by 14 and 15. The clamping force of the clamping device 1 is selected depending on the adhesive used and the maximum temperature obtained in the inductor. For example, this pressure may be in the range of 5-10 kg / cm. At the end of the heating cycle, the clamping devices 1 inside the inductor 2, one by one, are fed to the conveyor 28 by means of an actuator, where they are cooled either by the surrounding atmosphere or by a cooling device 29 made, for example, in the form of a fan. The jig 1 is then removed and reused. If the inductor 2 is made of a copper tube with a diameter of about 6 mm, wound with a step greater than this diameter, and with a number of turns more than four (the number of which is proportional to the speed of advancement of the clamping device 1 through the inductor 2), also connect the inductor 2 to the current source 5 s at a frequency of about 75 GHz, then at a distance of 10 mm between the pads 7 and 8 and the inner surface of the inductor 2, the polymerization temperature of the adhesive and the thermosetting coating of the pads 7 and 8 at about 212 ° C can be reached in about 65 seconds and maintained in tons for 5 seconds This mode provided the necessary connection between the pads 10 and 11 and the pads 7 and 8. The invention allows for a low cost of manufacture and energy consumption
