Изобретение относитс к отделочной обработке металлов резанием и может быть использовано при хонинговании шлицевых отверстий.The invention relates to the finishing treatment of metals by cutting and can be used when honing splined holes.

Известно устройство дл хонинговани шлицевых отверстий, содержащее корпус, несущий разжимную иглу и колодки с хонинговальными Орусками, размещенные в сквозных пазах корпуса, и упор дл ограничени углового поворота корпуса 1.A device for honing spline holes is known, comprising a housing carrying an expanding needle and pads with honing Oruski arranged in through slots of the housing and an abutment for limiting the angular rotation of the housing 1.

Ири ударах о боковые поверхности шлицев хонинговальные бруски крошатс , что снижает надежность работы устройства.Irie strikes the side surfaces of the splines with honing sticks of chips, which reduces the reliability of the device.

Цель изобретени - повышение надежности работы устройства путем предотвращени выкрашивани хонинговальных брусков .The purpose of the invention is to improve the reliability of the device by preventing chipping of the honing stones.

Поставленна цель достигаетс тем, что устройство снабжено жесткими упорами, равномерно установленными на корпусе, при этом угол между ос ми их симметрии и ос ми симметрии смежных хонинговальных брусков равен угловому шагу обрабатываемого шлицевого отверсти , а ширина упоров больше . ширины хонинговального бруска, причем упоры могут быть выполнены съемными, а колодки могут быть выполнены в виде упоров.The goal is achieved by the fact that the device is equipped with rigid stops evenly mounted on the body, while the angle between their axes of symmetry and the axes of symmetry of adjacent honing bars is equal to the angular pitch of the spline hole being machined and the width of the stops more. the width of the honing bar, and the stops can be made removable, and the pads can be made in the form of stops.

Устройство дл хонинговани шлицевых отверстий содержит корпус 1, разжимную иглу 2, колодки с хонбрусками 3, размещенные в сквозных пазах корпуса 1.The device for honing the slotted holes includes a housing 1, an expanding needle 2, pads with hon-bars 3 placed in the through slots of the housing 1.

На корпусе 1 размещены жесткие упоры 4. Ширина упоров 4 больше ширины хонбрусков 3.On the housing 1 are placed hard stops 4. The width of the stops 4 is greater than the width of the bar 3.

Боковые поверхности упоров 4 выступают на боковые поверхности хонбрусков 3 на величину, меньшую длины переходного участка от внешней поверхности шлнцевого отверсти к его боковой поверхности. Длина упоров 4 и их расположение в осевом направлении таково, что они предохран ют от выкрашивани хонбруски 3 по всей их длине.The side surfaces of the lugs 4 protrude on the side surfaces of the hon-bricks 3 by an amount less than the length of the transition section from the outer surface of the schlintsev hole to its lateral surface. The length of the lugs 4 and their location in the axial direction is such that they prevent chipping of the hon-brushes 3 along their entire length.

Claims

In operation, the body 1 of the device for honing from the machine tool receives reciprocating and reciprocating-rocking motion. The unclamping needle 2 from the stem placed in the machine spindle receives translational movement relative to the body 1. The conical part of the expanding needle 2 moves the pads with honbar bars 3 in radial direction in the grooves of the body 1, pressing against the surface to be treated. The amplitude of the reciprocating motion of the housing 1 of the device for honing is such that the side surfaces of the honbrusk 3 do not reach the side surfaces of the spline hole by the amount of the transition section from the outer surface of the spline hole to its side surface. If the housing 1 has slipped the reverse point of the reciprocating motion, then the stops 4 with the side surfaces will begin to interact with the side surfaces of the spline opening of the product 5, preventing the beam 3 from being struck and painted. FIG. 3, 4 shows another modification of the device for honing. It includes a housing 1, an expanding needle 2, hon-brushes 3, placed in the through slots of the housing 1. The stops 4 are made removable and fixed to the body 1 by means of pins 6 and a screw 7. During operation, the device replaces damaged or worn stops 4, such simplifies the manufacture of housing 1. The operation of this device is identical to that described above. FIG. 5, 6, the following modification of the device is shown. The housing 1 of the device is provided with additional through slots, and the uiors 4 are provided with additional hon-bars 8. The latter are placed in the additional grooves of the housing 1 and contact their bevels with the unclamp needle 2. During the operation of this device for honing, the stops 4 receive a radial movement from the conical part of the needle 2, unclenching as it moves progressively relative to the body 1 of the device. While the stops 4 are pressed additional honbruski 8 to the treated surface. Since the honing device is used in machining the flat splined hollows, the radial movement of the lugs 4 as the khibirus 8 is worn does not cause a change in the initial gap between the side surfaces of the lugs 4 and the splined holes of the product 5. This design of the honing device avoids chipping the hollows. Claim 1. Device for honing spline holes, comprising a housing carrying an expanding needle and pads with honing bars placed in through slots of the housing, and an abutment for limiting the angular rotation of the housing, in order to improve the reliability of the device by preventing chipping of honing bars, it is provided with rigid stops evenly mounted on the body, however, the angle between their axes of symmetry and the axes of symmetry of adjacent honing bars is equal to the angle at step treated spline holes and abutments honing width greater than the width of the bar.

2. A device according to claim 1, characterized in that the stops are made removable.

3. A device according to claim 1, characterized in that the pads are made in the form of stops. Sources of information taken into account during the examination 1. USSR author's certificate L 484974, cl. 24B 33/00, 1972.
