Description

Изобретение относится к абразивным инструментам и может быть использовано для шлифования и полирования деталей в машиностроении.The invention relates to abrasive tools and can be used for grinding and polishing parts in mechanical engineering.

Целью изобретения является повышение качества поверхности обрабатываемых деталей за счет повышения упругости круга.The aim of the invention is to improve the surface quality of the workpiece by increasing the elasticity of the circle.

На фиг.1 изображен лепестковый круг, вид на торец; на фиг.2 - сечение А-А на фиг. 1.Figure 1 shows a petal circle, view of the end face; figure 2 - cross section aa in fig. 1.

Лепестковый круг состоит из расположенных по окружности лепестков шлифовальной шкурки, изогнутых в направлении, обратном вращению круга, д<? полного соприкосновения, и ступицы 2 из композиции на основе эпоксидной смолы. На боковых сторонах лепестков выполнены спиралеобразные канавки 3 с расположенными в них шнурами 4, изготовленными из эластичного материала. Таким материалом может быть стекловолокно, ре1266726 зина и т.д. Шнуры закреплены в канавках при помощи клея.The petal wheel consists of circumferential petals of the grinding skin, bent in the direction opposite to the rotation of the wheel, d <? full contact, and the hub 2 of the composition based on epoxy resin. On the sides of the petals are made spiral-shaped grooves 3 with cords 4 located therein, made of elastic material. Such material may be fiberglass, re-1266726, etc. The cords are fixed in the grooves with glue.

’’

Описываемая конструкция за счет 5 возможности деформации лепестков сочетает в себе повышенную и постоянную плотность лепестков с наличием плавности входа и их упругости.The described design, due to the 5 possibilities of deformation of the petals, combines an increased and constant density of the petals with the presence of a smooth entrance and their elasticity.

Claims

The invention relates to abrasive tools and can be used to grind and polish parts in mechanical engineering. The aim of the invention is to improve the quality of the surface of machined parts by increasing the elasticity of the circle. 1 shows a petal circle, a view of the end; in Fig.2, section A-A in Fig.1. The flap wheel consists of petals of grinding cloth 1 arranged around the circumference, curved in the direction opposite to the rotation of the circle, etc. of complete contact, and the hub 2 of the composition based on epoxy resin. On the sides of the petals are spiral-shaped grooves 3 with cords 4 arranged in them, made of elastic material. Such material may be fiberglass, rubber, etc. Etiury secured in the grooves with glue. I The described structure, due to the possibility of deformation of the petals, combines the Povshinuk and the constant density of the petals with the presence of a smooth entrance and their elasticity. The invention has a flap abrasive wheel containing a hub, on which the petals of the abrasive cloth are tightly mounted relative to each other, and a fixation element that differs in that, in order to improve the quality of the treatment by means of elasticity of the circle, the element of the petals fixation is made in the form of an elastic cord and spiral grooves on the side surfaces of the circle for accommodating said cord.
