(5) УСТРОЙСТВО дл АБРАЗИВНОЙ ОБРАБОТКИ(5) DEVICE FOR ABRASIVE TREATMENT

II

Изобретение относитс к безразмерной абразивной обработке, например полированию, гл нцеванию -и т.п.v и Может быть использовано в разных расл х машиностроени .The invention relates to a dimensionless abrasive treatment, for example, polishing, glazing, etc., and can be used in various engineering fields.

Известно устройство дл абразив ной обработки, содержащее корпус, внутри которого размещен шпиндель с . закрепленным на нем при помощи шайбы с гайкой эластичным инструментом СП.A device for abrasive machining is known, comprising a housing within which a spindle is placed. fixed on it with a nut washer with an elastic tool JV.

Недостатком, известного устройства вл етс низкое качество обработки. - изобретени - повышение качества обработки.A disadvantage of the known device is the low quality of processing. - invention - improving the quality of processing.

Поставленна цель достигаетс тем, что на одном торце гибкой части инструмента закреплен кольцевой торцовый кулачок, установленный с возможностью взаимодействи с введенным в устройство роликом, ось которого закреплена на корпусе, а на другом торце - кольцо с упругим элементом, установленным с возможностью контакта с шайбой, закрепленной на шпинделе.The goal is achieved by having an annular face cam mounted on one end of the flexible part of the tool, which is interoperable with a roller inserted into the device, the axis of which is fixed to the body, and on the other end is a ring with an elastic element mounted to be in contact with the washer, fixed to the spindle.

На фиг. 1 изображено предлагаемое устройство, разрез; на фиг. 2 узел I на фиг. 1.FIG. 1 shows the proposed device, the cut; in fig. 2, node I in FIG. one.

На станине 1 в вертикальных направл ющих 2 установлена с возможностью вертикального перемещени инструментальна головка 3, в корпусе k которой с возможностью вращени на подшипниках 5 расположен шпиндель 6, привод во вращение которого.осуществ10 л етс электро- или гидродвигателем 7 закрепленным, например, на головке 3 или корпусе .On the bed 1 in the vertical guides 2, the tool head 3 is mounted with the possibility of vertical movement, in the case k of which the spindle 6 is rotatably mounted on the bearings 5 and driven into rotation by the electric motor or hydraulic motor 7 fixed, for example, on the head 3 or enclosure.

На оправке 8 шпиндел 6 с буртом с помощью шайбы 9 и гайки 10 закреп15 лен инструмент 11 с эластичными элементами 12, выполненный, например, в виде волос ной или текстильной щетки , войлочного, сезалевого или поропластового полировальника и т.п.On the mandrel 8, a spindle 6 with a collar using a washer 9 and a nut 10 fastened 15 a tool 11 with elastic elements 12, made, for example, in the form of a hair or textile brush, a felt, sesal or poroplast polishing pad, etc.

Claims

Depending on the type of treatment (polishing, glossing, etc.), an elastic tool with an abrasive applied to its periphery or 8 processing zone is fed with an abrasive paste (suspension). The workpiece 13 is placed on the table k of the caliper 15 which gives it the necessary shaping displacements. The tool head 3 by the flexible element 16, thrown over the guide rollers 17 mounted on the frame, is connected to the load 18, the magnitude of which specifies the necessary force of pressing the tool to the workpiece 13- To remove the tool upwards, when the part is changed, the power cylinder 19 located on the frame serves , the rod of which interacts with the tool head 3. On the free end of the tool 11 on its elastic elements 12 is fixed a ring 20, to which the elastic element 21, made, for example, is pressed against the washer 9 In the form of rubber rings. On the opposite end of the tool on its flexible elements fixed annular cam 22, made, for example, in the form of an oblique washer. With a cam contact. It makes it possible for the roller to rotate freely on the axis 23.

2. The roller axis with the help of the bracket 25 is fixed on the 4-spindle i case. The ring 20 and the cam 22 are interconnected by bolts 2b. When the device is working, the spindle rotates, and with it the tool 11, the workpiece 13. The cam 22, rotating with the tool, interacts with the roller 23 and deflects it in the axial direction. Together with the cam, the axial movements (vibrations, vibrations) are also elastic tool elements 12 due to its periodic inclination to the spindle axis together with the cam. In the opposite direction, the tool with the cam is displaced by an elastic element 21 that is compressed when the cam is displaced with the tool. The frequency of axial vibrations of elastic elements is in the range of 100-5000 vibrations per minute, and the amplitude is from 1 to 15 mm. With a lower frequency of vibrations, the magnitudes of the positive effects are reduced, and with a greater frequency, the elastic elements do not have time to return to their original position. The frequency of vibrations is set by the number of revolutions of the tool and the number of protrusions and cavities on the cam. The amplitude and oscillation frequency of the ends of the elastic elements are finally selected experimentally depending on the material of the workpiece, the required surface roughness, etc. Thus, the proposed device can improve the quality of processing. An abrasive machining device comprising a body inside which a spindle is housed with an elastic tool fixed on it with a nut washer, characterized in that, in order to improve the quality of machining, an annular end cam mounted with one end of the flexible part of the tool the possibility of interaction with the roller inserted into the device, the axis of which is fixed on the body, and on the other end a ring with an elastic element installed with the possibility of contact with the washer is fixed flax on the spindle.
