Description

The invention relates to machine tool making and can be used to remove workpieces from a grinding machine with a round table electromagnetic table.

The aim of the invention is to improve the cleaning and straightening of the table when magnetically processing soft materials.

FIG. I there is no steep electromagnetic etol, on which, in the discharge area, there is a device for removing workpieces, cleaning and dressing the table; in fig. 2 - the same, side view; in fig. 3 - a device for removing parts when machining ferromagnetic parts on the table, having a residual magnetization on the working surface; in fig. 4 is a variant of making the correct ring when machining diamagnetic materials.

The device includes a modular, correct ring-puller 1 mounted on the mirror with an end surface. Round table 2 grinding machine. The correct ring receives vigorous movement through the gearmotor 3. The parts to be machined 4 arrive at the node of the platter wheel 5 and then into the discharge chute 6. The round electromagnetic table has a magnetized I and non-magnetic AND zones.

The central part of the electromagnetic table is closed by a lid 7, the external surface of which is also a supporting base for the workpieces. 8 poles of 8 electromanitic coils placed inside the table (conventionally not shown) come to the surface of the table. The prefabricated ring consists of an outer disk 9 in which shaped grooves 10 are made, covered with elastic material II, intended for removal of machined parts; For removal of ferromagnetic products of P-plating, there is an abrasive collar 12, rigidly connected (for example, with glue) to disk 9. Through the working end of the abrasive ring 12, through grooves in which the magnetic plates 13, which are rigidly glued, are rigidly glued. removal of ferromagnetic products. The grinding waste removed from the table enters the tank.

The device works as follows.

The workpieces 4 enter the loading zone on the rotating station; 1 2 and into the grinding zone under the abrasive wheel 5 at an operating feed rate (1-2 m / min during the processing of ferrite parts). Before the grinding node Kpyi comes in and during processing, the parts are clamped to the surface of the table by a magnetic field (magnetized zone I). During grinding, the machined parts fall into non-magnetic zone II (having a low residual magnetization of 5-8 mT) and are removed from the table with a right ring, its outer rim with shaped grooves 10 covered with elastic material m. From the table, the processed parts are delivered to the discharge chute 6.

The correct ring is rotated in the direction of rotation of the table by means of the motor gear 3, and the rotational speed of the outer rim of the disk of the correct ring is slightly higher than the rotational speed of the magnetic table of the machine.

Grinding waste on a table mirror receives a node abrasive, a regular ring 12, in which plates 13 are located, made of a soft magnetic material, for example iron .4. Residual magnetization of the poles and the table magnetics concentrates fine grinding waste around. -Provision of no-table mirrors.
