Изобретение относитс к инструмей- тальному производству и может быть применено, гфи изготовлении разверток.The invention relates to toolmaking and can be applied when manufacturing sweeps.

Известно устройство дл заточки инструментов с криволинейной режущей кромкой , выполненное в виде центровой огфав- ки, на которой установлены два кронштейна с соосными центрами 1J.A device for sharpening tools with a curved cutting edge, made in the form of a center head, on which two brackets with coaxial centers 1J are mounted, is known.

Однако это устройство не обеспечивает повышенного качества заточки вследствие значительной площадки зоиы резани и, как следствие, большой силы, вызывающей по вление биени режущих кромок.However, this device does not provide improved sharpening quality due to the large area of the cutting area and, as a result, a large force causing the appearance of a beating of cutting edges.

Цель изобретени - повышение качества заточки.The purpose of the invention is to improve the quality of sharpening.

I Эта цель достигаетс тем, что центры установлены наклонно таким что их осева лини расположена под углом скрещивани с осью центровой оправки.I This goal is achieved by the fact that the centers are set obliquely such that their axial line is located at an angle of intersection with the axis of the center mandrel.

На фиг. 1 показано предложенное устройство , общий вид; на фиг. 2 - А-А на фиг. 1.FIG. 1 shows the proposed device, a general view; in fig. 2 - A-A in FIG. one.

Устройство состоит из центровой О1фавки 1, на которой установлены 2 и 3 с центрами 4 и 5. На центровой оправке может быть также установлен упор 6. Центры 4 и 5 установлены наклонно таким образом, что осева лини da расположена под углом скрещивани ш по отношению к оси центровой оправки 1. На центровой ощэавке 1 имеетс также упор 7.The device consists of a center O1 alphabets 1, on which 2 and 3 are installed with centers 4 and 5. An emphasis 6 can also be mounted on the center mandrel. Centers 4 and 5 are installed obliquely so that the center line da is located at an angle of crossing with respect to Center mandrel axles 1. There is also a stop 7 on the center plate 1.

Устройство работает следующим образом .The device works as follows.

Claims

The center mandrel 1 is installed in the centers 8 and 9 of the grinding machine, and the sharpened scan 10 is installed 15 in the centers 4 and 5. At the same time, the working part 11 of the sweep 10 is positioned at the calculated minimum distance of the S axis. Sharpening is carried out by rotating the device around the OS and 6G (T of the central O1 alphabet. By locating the axial line aa of the centers 4 and 5 at an angle of intersection with respect to axis 5, the sharpening of the sweep with a curvilinear 3905 cutting edge with high accuracy of shape takes place. due to the slight cutting of the cut, the beating of the teeth of the reamer is reduced. Thus, the quality of the sharpening increases. Formula of the Invention The device for sharpening the reamers with a curved cutting edge, made in the form of a center mandrel, on which There are two brackets with OO14 yosny centers that distinguish ё-5 with the fact that, in order to improve the quality of the handles, the centers are set obliquely in such a way that their center line is set at an angle of intersection with the axis of the center mandrel. i, Menitsky, ID, et al., Universal Sharpening Machines, M., Mashinostroenie, 1968, pp. 180, figure 104.
