Abstract

The invention relates to toolmaking and relates to flap wheel designs for finishing operations. The purpose of the invention is to improve the quality of the treated surface. To do this, between the packets of petals 1 are placed inserts 2 of polishing material, made in the form of rods, which can be conical or cylindrical in shape. The inserts can be positioned so that they form a sine wave around the periphery of the tool. 2 hp f-ly, 2 ill.

The invention relates to toolmaking and relates to structures for peppered circles for finishing operations.

The aim of the invention is to improve the quality of the treated surface.

FIG. 1 shows a section of a polishing tool along a polishing element; in fig. 2 - sweep the periphery of the instrument.

The diameter is 200 mm, the diameter of the hub is 3 100 mm, the width of the petal is 1 40 mm, the number of inserts 2 is 6, the shape is cylindrical, with a diameter of 10 mm, the location around the periphery of the circle is uniform through 5 60 °, the location of the inserts 2 is 3 : 1-, 3- are shifted from the axis of petal I by 5 mm to the left, 4-, 6- are shifted from axis 8 of petal 1 by 5 mm to the right, 2- and 5- are shifted from axis 8 of petal 1 by 15 mm

The polishing tool contains a pair of ig, respectively, left and right, i.e. the form

(The plates of abrasive petals 1 and polysolating inserts 2, mounted on an alternating 3, side covers 4 1 central core 5, with which they are fastened, for example, using a nut 6 i lock nut 7, polishing inserts 2 are made in the form of rods mounted on the hub 3 with an offset from the axis of symmetry of the packages 8, the polishing insert 2 can 6 or 1 are located on the hub 3 with an image of the trajectory of the arrangement corresponding to a sinusoidal profile. During processing, the part is brought into contact with the abrasive surface of the petals 1 of the inserts 2, they are deformed, worn out. As the wear of the insert 2 and the abrasive lobes 1 are replaced, the conical shape of the inserts makes it possible to take into account the divergence of the abrasive lobes 1 as they approach the periphery of the circle and provide the best

a sinusoidal profile, and inserts .- ,,. The conditions for the deformation of the petals 1 relative to 5 can be made in the form of straight inserts 2 by providing pivots or tapered troughs along the entire length of the petal 1.

The manufacture and assembly of polishing

The tool is performed by the following polishing tool allows

Increase the quality of processing, namely

 Abrasive cloth is cut into strips, 25 reduce roughness parameters, in

for example, on disc shears with a width resulting from a change in the angle of interaction

equal to the length of the petal 1, and makeplots with the treated surface

The circle is ready to workTe. The number of inserts 2 can be from six to ten. When the number of inserts 2 is less than six, the conditions for deforming the petals 1 worsen, and when

Claims (2)

1. Polishing tool on the hub the number of petals 1 over ten diminution 45 of which are installed packages of abrasive the magnitude of the abrasive surface of the petals is spared, and there is a circle between them. The diameter of the insert 2 can be equal to 15-25% of the width of the hub 3. When the dia-insert 2 is less than 15% of the width of the hub 3 worsening conditions of petal deformation - ,,, KDB 1, and with an insert diameter of more than 25%, 50 rods, which is installed with c. the hub caps 3 decreases in proportion to the axis of symmetry of the packet, abrasive surface of the wheel. Location 2. Instrument} 1t according to claim 1, different inserts 2 along the periphery of the circle, by the fact that MiepHoe, while they are placed in such a form of a sinusoid in a circumferential direction so that the center of the insert does not fall into the direction of the instrument. on the axis of the 8 petals 1. Inserts 2 can be3. Instrument on PP. 1 2, different made in the form of rods as cylindrical in that the inserts are made in the form of a cone chesky, and conical shape. For example, they are installed with a smaller base on the stumer, the polishing tool has outer cavity. The diameter is 200 mm, the diameter of the hub is 3 100 mm, the width of the petal is 1 40 mm, the number of inserts 2 is 6, the shape is cylindrical, with a diameter of 10 mm, the periphery of the circle is uniform through 60 °, the arrangement of the inserts 2 across the width of the hub 3 is the following: 1-, 3- are displaced from the axis of the petal I by 5 mm to the left, 4-, 6- are displaced from the axis of 8 petals 1 by 5 mm to the right, 2- and 5- are displaced from the axis of 8, petals 1 by 15 mm the location path corresponds to a sinusoidal profile. During processing, the part is brought into contact with the abrasive surface of the petals 1 of the inserts 2, they are deformed and wear. As the insert 2 is worn and the abrasive blades 1 are replaced. The conical shape of the inserts allows to take into account the divergence of the abrasive blades 1 as they approach the periphery of the circle and provide the best  inserts along the hub irin and the perimeter of the circle with the formation of a sinusoidal profile. inserts of polishing material are provided, characterized in that, in order to improve the quality of the treated surface, each insert is made in the form of petals, and in between ,,, rod that is mounted with offset Q T SG / ./
