Description

one

The invention relates to a spindle head of a circular machine and can be used in the woodworking industry.

The known spindle head of the circular blading machine includes a hollow cylindrical body with a bearing, a drive pulley, a sleeve mounted for translational displacement along the keyway groove of the body, a holder with knives l.

Also known is a spindle head of a circular blade machine, comprising a hollow cylindrical body with bearings mounted on the body of a holder with knives, a sleeve having an internal surface in the form of a truncated cone and mounted with the possibility of reciprocating movement, a pulley and a driving carriage 2.

However, due to the complex design of the known heads are not reliable enough in operation.

A: The purpose of the invention is to simplify the design of the spindle head - achieved by the fact that the spindle head is equipped with two magnets, one of the KOTOF "EC mounted on the sleeve and located with a gap inside the other magnet mounted on the drive carriage.

FIG. Figure 1 shows the kinematic scheme of the spindle head; in fig. 2 -: view A of FIG. one...

The spindle head consists of a cup 1 rigidly fixed on the machine bed, on which in bearings 2 a hollow body 3 with a driving pulley 4, knives 5 and a sleeve 6 having an inner surface in the form of a truncated cone is installed. The sleeve is installed with the possibility of reciprocating movement of the slots of the hollow body 3. An annular magnet 7 is rigidly fixed on the sleeve, which is installed with a gap inside the magnet 8. The magnet 8 is mounted on an adjustable mechanism for driving the sleeve 6, which consists of a carriage 9 and a controlled hydraulic cylinder 10 During operation, the hollow body 3 is rotated on the cup 1 in bearings 2 by means of a drive pulley 4. When the hollow body 3 rotates, the blades 5 are thrown by the action of centrifugal forces to the inside of the sleeve. and 6 and copy it over BpxrfocTb. The progressive movement of the sleeve along the axis causes the times.

) the movement of knives. To move the sleeve progressively, the hydraulic cylinder 10 is moved, which moves the carriage 9 with the magnet 8. The magnet 8 attracts the ring magnet 7 and does not follow it along with the bushing. Moving the carriage 9 according to a predetermined program allows the knife 5 to be widened by this program and Tali desired profile. The use of the invention allows to simplify the arrangement of the spindle, to simplify the mechanism for moving the bushings and to increase the reliability of the work of the spindle. ;. The spindle head is round-circular; a machine tool comprising a hollow cylindrical body with bearings mounted on the body of the holder with knives, a sleeve having an internal surface in the form of a truncated cone and installed with a transverse displacement, a pulley and a drive carriage, characterized in that in order to simplify the design of the spindle head, the latter is equipped with two magnets, one of which is mounted on the sleeve and located with a gap inside the other magnet mounted on the drive carriage.
