Description

Изобретение относится к области машиностроения и может быть использовано для шлифования поверхностей плоских деталей.The invention relates to mechanical engineering and can be used for grinding surfaces of flat parts.

Известно устройство для шлифования, обеспечивающее двухступенчатое шлифование шариков путем последовательной принудительной подачи их в зону обработки [1].A device for grinding, providing a two-stage grinding of balls by successive forced feeding them into the processing zone [1].

Недостатком известного устройства является невысокая производительность, обусловленная двухступенчатым шлифованием, и невозможность одновременной обработки двух плоских поверхностей.A disadvantage of the known device is the low productivity due to two-stage grinding, and the inability to simultaneously process two flat surfaces.

Целью изобретения является повышение производительности и расширение технологических возможностей. ₁₅ The aim of the invention is to increase productivity and expand technological capabilities. _fifteen

Указанная цель достигается тем, что в устройстве для шлифования содержащем питатель, два соосно установленных шлифовальных круга, привод вращения кругов и непод- 20 вижную направляющую, расположенную между кругами, направляющая выполнена со сквозным пазом по форме спирали Архимеда, а в одном из кругов выполнено центральное отверстие, соосно которому установлен питатель.This goal is achieved by the fact that in the grinding device comprising a feeder, two coaxially mounted grinding wheels, a rotational drive of the wheels and a stationary guide located between the circles, the guide is made with a through groove in the shape of an Archimedes spiral, and in one of the circles a central hole coaxial to which the feeder is installed.

Устройство состоит из станины 1, на которой смонтирован привод 2, придающий разнонаправленное, с разной скоростью вращение двум шлифовальным кругам 3, между которыми расположена направляющая 4, выполненная в виде плоской ленты по профилю спирали Архимеда, в центр которой направлено * устье питателя 5.The device consists of a bed 1, on which the drive 2 is mounted, which rotates two grinding wheels 3 in different directions at different speeds, between which there is a guide 4 made in the form of a flat tape along the profile of the Archimedes spiral, to the center of which * the mouth of the feeder 5 is directed.

Устройство работает следующим образом.The device operates as follows.

Детали загружаются в питатель 5, из которого поступают к центру направляющей 4, а затем в зазор между плоскопараллельными кругами 3, вращающимися в разных направлениях и с различными скоростями.The parts are loaded into the feeder 5, from which they go to the center of the guide 4, and then into the gap between plane-parallel circles 3, rotating in different directions and at different speeds.

Вследствие разницы чисел оборотов кругов 3 деталь движется по инерции к их периферии по архимедовой спирали направляющей 4, при этом происходит шлифовка плоскопараллельных поверхностей деталей. В зависимое3' 979084 ти от материала режим обработки регулируется посредством привода 2. ‘Due to the difference in the numbers of revolutions of the circles 3, the part moves by inertia to their periphery along the Archimedean spiral of the guide 4, while grinding of plane-parallel surfaces of the parts occurs. Depending on the material 3 '979084, the processing mode is controlled by drive 2. ‘

Использование изобретения позволит повысить производительность шлифовальных станков при двустороннем шлифовании.The use of the invention will improve the performance of grinding machines with double-sided grinding.

Claims

The invention relates to the field of mechanical engineering and can be used for grinding surfaces of flat parts. A device for grinding, which provides two-step grinding of balls by successively forcing them into treatment zone 1, is known. A disadvantage of the known device is low productivity due to two-step grinding, and the impossibility of simultaneously processing two flat surfaces. The aim of the invention is to increase productivity and expand technological capabilities. This goal is achieved by the fact that in a grinding machine containing a feeder, two coaxially mounted grinding wheels, a wheel rotation drive and a stationary guide located between the wheels, the guide track is made with a through groove in the shape of an Archimedes spiral, and in one of the circles there is a central hole coaxially installed tpgatel. FIG. 1 shows a grinding device; in fig. 2 shows section A-A in FIG. 1. The device consists of a frame 1 on which a drive 2 is mounted, which gives a multidirectional rotation to two grinding wheels 3 at different speeds, between which a guide 4 is located, made in the form of a flat ribbon along the profile of an Archish spiral, in the center of which the mouth of the feeder 5 The device works as follows. The parts are loaded into the spatula 5, from which they are directed to the center of the guide 4, and then into the gap between the plane-parallel circles 3, rotating in different directions and with different speeds pl. Due to the difference in the number of revolutions of the circles 3, the part moves by inertia to their periphery along the Archimedean spiral of the guide 4, and this results in grinding of the plane-parallel surfaces of the parts. Depending on the material, the processing mode is controlled by the drive.

2. The use of the invention will improve the performance of grinding machines for double-sided grinding. The invention The device for two-sided flat grinding, containing a feeder, two coaxially mounted grinding wheels, a hitch of rotation of the circles and a fixed guide located between the circles, characterized in that, in order to improve performance and expand the technological capabilities of the device, the guide is designed with a through a groove in the shape of an Archimedes spiral, and in one of the circles a central hole is made, coaxially with which a feeder is installed.
