A known machine for processing core elements of a magnetic circuit containing a base on which a worktable, grinding wheel equipped with a rotation drive, a device for transporting workpieces, made in the form of an infinite flexible link 1, are installed. A disadvantage of the known machine is its limited technological capabilities, since it is only possible to machine parts such as plates of small thickness and the impossibility of machining parts of complex geometric shapes. Also known is a machine for processing ferromagnetic cores, containing a base on which a working table is installed, a grinding wheel equipped with a drive for its rotation, a device for transporting machined parts, made in the form of an endless flexible link equipped with elements for fixing them, and a device for pressing the machined parts Lei to the surface of the desktop 2 The disadvantage of this machine is the complexity of the design. The purpose of the invention is to simplify the design. The goal is achieved by the fact that in a machine tool for processing ferromagnetic cores containing a base on which a work table is installed, a grinding wheel equipped with a drive for its rotation, a device for transporting the workpieces, fulfilled as an endless flexible link provided with elements for fixing them , and the device for pressing the workpieces to the surface of the working table is made in the form of a roller mounted opposite the grinding wheel. Moreover, the roller is made of elastomer, the endless flexible link is made in the form of a hinge chain, and the fixing elements of the machined parts are made in the form of plates with grooves fixed on the hinge chain, and the machine is equipped with devices for creating a prestressed working table made in the form of a screw pair. FIG. 1 shows the process ferromagnetic core; Fig. 2 is the same variant (Fig. 3 is a top view of Fig. 1; Fig. 4 is a top view of Fig. 2; Fig. 5 is a plan view of a machine for processing ferromagnetic cores; Fig. 6 is a front view of the machine for processing ferromagnetic cores, Fig. 7 is a section A-A in Fig. 6, and Fig. 8 is a section B-B in Fig. 5, and Fig. 9 is a section C-B in Fig. 6 5, The machine for processing ferromagnetic cores is designed for processing cores having a configuration similar to the cores shown in Figures 1 to 4. Core 1 (Fig. 3) has two side openings 2 and a central cylinder The core part 3, the end surface of which 4 is flush with the plane of the side edges of the core 5. The core 6 (FIGS. 2 and 4) has two side openings 7 and a central part with an annular cross section 8 designed to accommodate a screw-in central ferromagnetic core, with This end face 9 of the central part is flush with the plane of the side edges 10 of the core 6. Two cores of this type are intended: for assembly along the side edges after winding at least one winding on their center battening part. The inductance thus created may have different values depending on the air gap, which is performed between the cores of the cores on a machine in accordance with the invention, i.e. the treatment of at least one specified end surface is carried out with an accuracy of the order of a micron or a fraction of a micron. This treatment can be carried out with a grinding wheel, preferably in two successive stages, the first is coarse and: the second is the finishing process itself. The machine for processing ferromagnetic cores (Figs. 5-9) contains a base 11, on which a support plate 12 is fixed, on which two columns 14 and supports 15 are mounted on two supports 13, and on a support a working table 16 of the machine is fixed. The bottom sections are 17, 18, separated by an intermediate plate 19. The support 15 is adjusted along each column by means of a sleeve 20 with a bottom ring interacting with a nut 21 screwed onto the cut part of the column and with a locknut 22. The plate 17 corresponds to the position of the roughing one. processing , in which the crossbar 23 intersects the support 15 in the hole 24 and the plate in the hole 25, the exit to the adjustable level by the working plane of the table. The plate 18 corresponds to the finishing position, the grinding wheel of which 26 crosses the support 15 in the hole 27 and the plate in the hole 28, the output is also at an adjustable level above the plane of the table. Each grinding wheel is mounted between the axle 29 with the shoulder and the clamping washer 30, which is pressed against the locking nut 31, which is screwed onto the axle. The axis 29 is connected to the spindle 32, the body 33 of which is blocked by a flange 34 in the semi-nest 35, made in the support block 36, which is height-adjustable to set the grinding wheel to the position required during processing. Adjustable height adjustment is carried out using an insert 37 under the block 36 between the intermediate slider 38 and the guide 39, forming an additional insert wedge on the base plate 12. All this is fixed on the base plate 12 by means of a spring — 40, pressed by bolts 41, the rods of which are t through block 36, while the slider 38 and the guide 39 are in the corresponding holes, and they intersect the insert 37 in the circular slot 42, which allows for a P1 displacement during adjustments. The latter is provided by means of an adjusting screw 43, an insert that interacts with the threaded hole 44 and is mounted by a rotating plate 45, which is fixed to the base plate 12, while the screw is held axially relative to the front plate 45 between the leg 46 on it and the rotary knob 47. The spindles 32 of both grinding wheels are driven by a common belt drive 48 with a driving pulley 49 mounted on the output shaft of the electric motor 50 and with a tensioning pulley 51 containing a lever g of bracket 52 of pulley 51 mounted pivotally at point 53 on the rear section of the base plate 12 connected to the hinge at point 54 in the end plug of the control rod 55, the free threaded end of which interacts with the knurled adjustment nut 56 supported on the plate 57 mounted on the plate 12. In front of each grinding wheel and above the corresponding table plate, the device for pressing the workpieces to the surface of the working table is installed with the possibility of height adjustment relative to the support; roller 58 of elastomer, for example polyurethane. The roller 58 is mounted removably on the support 59 with a collar and is fastened under a washer 60 screwed onto the support. The support 59 is mounted on a sleeve 61 mounted with a bearing on a shaft with a shoulder 62, which is fixed with an end nut 63. The shaft 62 is mounted for movement along the height in the slots 64 of the guide 65, fastened. on the support 15, the slide 66, through which the shaft 62 passes without a gap, and which has a vertical threaded hole, which includes a height adjustment screw 67 with axial locking at the top of the guide 65 between the shoulder and the height adjustment knob 68. The roller-roller holder 62, after adjustment, is locked by tightening on the guide 15 of the shoulder 69, on the one hand, and the washer, pressed with a nut and lock nut 70, screwed onto the end of the shaft, on the other hand. The guides 65 are mounted on the support 15 in a movable manner. parallel to the plane of the grinding wheel with screws 71, passing through the circular slits 72 of the base for fastening these directions. of The ferromagnetic cores 1 to be processed are moved along the worktable in a straight line of two grinding positions by means of a transport device containing an endless chain 73 running parallel to the plane of the table 16, and along the link engages with pinion gear 74 and idle gear 75, which They are mounted on a support plate 76, with a leading edge behind the working table and fixed with screws to the console and 77, which themselves are fixed with screws on the side of the table support 15. ,, As seen in FIG. 9 leading neck-; the turn 74 is clamped between two clutch washers 78 in the upper part of the shaft with a ring 79, fitted with a clamping nut 80, the lower part of which, rotating in the sleeve 81 of the support plate 76, bears the gear 82, which engages with the gear 83 of the gearbox electric motor 84. The idler gear 75 has an axis 85 mounted in the sleeve, which can slide in the circular slot 86 of the support plate 76, allowing the tension of the chain to be adjusted using an eccentric 87 that interacts with the sleeve and locking it by clamping the nut on the support plate 76. In this example, one of the two axes of the chain links, indicated by 88, continues the link above the plane and on each pair of adjacent axes 88 there is a fixation element for machined parts 89 containing a flat, muddy part designed for free passage with grinding wheels 23, 26 and corresponding on the press rollers 58, which has grooves 90 for positioning and guiding the ferromagnetic cores 1 for processing. This plate portion leads to a mounting bridge 91, which has a hole on one of the axes 88 and a circular hole 92 on the adjacent axis 88 to accommodate the measurement of the axial distance when the chain passes on gears 74 75. These bodies have different sizes for each categories of processed cores, depending on their geometric shape or size, and they are easy to remove and replace each time the cores are changed. At the grinding position, the endless chain 73 is precisely guided along its path by means of two opposite lateral guides 93,94, interacting with the axes of the links and fixed on the support 15. Filling the hole 90 with ferromagnetic cores 1 is provided by the chute 95 with the descent of parts under the action of The force of gravity placed in a vertical position opposite the zone of passage of the holes 90 Bbmie of the position of the grinding wheel for roughing. This chute consists here of two profiles 96, made in accordance with the contour of the core being machined and fixed with screws ... against each other on the support arm 97. mounted in the form of a bracket on the support shaft 98 and can be adjusted in height on the base 99 of the mount. parts of the support 15 and locked with a clamp on the clamping screws 100. To reduce the friction of the side edges of the machined cores on the table, the plates 17, 18, 19 are covered with equal plates of alumina 101. In addition, the support 15 of the table and the investigator on a table, subject to pre-stressed with a force: up force bearing cores during their processing. This prestress is obtained with a screw device, the screw 102 of which freely passes through the table and is screwed into the rack 103 on the base plate 12, provided with a support head 104 resting on the table, and has a square 105 on top. This solution allows to obtain air gaps of the order of half a micron with the ability to quickly adjust the pressure rollers 58, carried out on several test parts, and which remains stable during operation, and this accuracy is achieved without the use of spindles with fluid-friction bearings. The machine for processing ferromagnetic cores operates as follows. The processed cores 1 are fed to the fixing elements of the machined parts 89 when adjusting the height of the chute 95 relative to the working table 16, i.e. when adjusting, the height of the base of the profiles 96 relative to the working table is set to an amount greater than the thickness of the core 1, but smaller than the two cores one set to the other, in this way, automatically feeds the parts into the slots 90. The supply of appropriately directed parts to the chute 95 can be provided in any manner. The machine works with the direction of rotation and drive chain and grinding discs indicated by arrows in the drawing. 71109 Cores 1, selected one by one downstream of the chute 96, are moved one after the other onto the work table 16 and thus in the first stage pass between the grinding wheel dp black and 5 processing 23 and the corresponding pressure roller 58, which is adjusted so that rotating indentation. in contact with the bottom of the core 7, and thus provides the specified adjustable pressure distributed over the core 1 during its processing. The same thing happens when the finishing pass between the grinding wheel - finishing 26 and the corresponding (the 58k pressure roller with the invention) allows to simplify the design of the machine for processing ferromagnetic cores.
