Abstract

The invention relates to metal cutting and is intended for use in the repair of electric motors, generators and other devices having a multi-phase design. The aim of the invention is to increase the reliability and performance by eliminating the skew of the tool in the groove to be machined and using the forward and reverse stroke of the slider when machining the grooves. One of the electromagnets 15 is switched on, the bark of which moves the spring-loaded locking element 14 into the groove of the core. After the shaft 18 of the core 5 is rigidly clamped, the electromagnet 15 is turned off, the locking element 14 is withdrawn from the groove of the core and the tool is inserted into the oriented groove of the core. The groove is machined in one direction. Then the shaft 18 of the core 5 is released from the clamp, it is rotated by the step of arranging the grooves of the core, another electromagnet 15 is turned on, and its locking element 14 is moved to the next raw groove of the core. The shaft 18 is clamped, the locking element is inserted into the oriented groove of the core. The next slot is machined in the other direction. 3 il. (L

The invention relates to the processing of metals by cutting and is intended to be used in the repair of Koreans of electric motors, generators and other devices having a multi-stage structure.

The purpose of the invention is to increase reliability and productivity by eliminating the skew of the tool in the groove to be machined and using the forward and reverse stroke of the slider when processing the pelvis.

FIG. 1 shows a device for processing the core grooves, a general view; on f) Hr. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one.

Device for grooving

contains placed on the frame 1, the remote control 2 measles moves the spring-loaded wedge 14 of the control, the slider 3, the device 4 for in the raw groove of the core. The shaft 18 of the core 5 is clamped in the fixture 4 for mounting and turning the core 5. After this, it inserts the tool 9 into the groove 12 and processes it. At the moment of combining the control element 11 with the sensor 7, the limiting stroke of the slide 3 is switched off by the electric actuator 6 to move 5 the PII of the slide 3 and the electric actuator 10 of rotation of the holder 8 of the tool 9 according to the signal from the sensor 7, at the same time the slide of the slide 3 stops rotating. Shaft 18 cor 5

10 is released from clamping in the mechanism 17 of turning the device 4 for mounting and turning the core 5 and turning it around its axis by one step of the slot of the core. On command from the remote control 2, the other electromagnet 15 is turned on and

The electromagnet 15 is turned off, the set is barked and the core 5 is turned, the electric drive 6 is used to move the slide 3, and the sensors 7 limit the travel of the slide 3.

On the slider 3, a holder 820 is mounted, which removes the spring-loaded wedge 14 of the tool 9, the rotational drive 10 from the groove of the core. Then, the electric holder 8 of the tool 9 and the element-drive 10 of rotation of the holder 8 of the tool 11, which control the sensors 7, are turned on. On the core 9 and the electric drive 6 for the interleaver 8 of the tool 9 is placed the slide mechanism 3. In this way, the tool 9 | of 1 fixing the position of the grooves of the core moves in the opposite direction and forms 12, consisting of two symmetrically 5, working the next groove of the core. After about -1 -1 parallel to the relative working of the groove of the core, the cycle is repeated until

esi 13 tool holder 8 9 fixing elements 14, made in the form of spring-loaded wedges moved by electromagnets 15.

The fixture 4 for mounting and moving the bark 5 contains the front headstock 16 L placed on it by the mechanism 17 for turning and securing the shaft 18 of the bark 5 and the tail headstock 19, while the axis 20 of the fixture 4 coincides with the axis of the core.

The device works as follows.

With the help of crane equipment, measles 5 is installed in the centers of the front beam 16 and the rear beam 19. From the control pulley 2, the command is issued to turn on one of the electromagnets 15, 40 | measles which moves the spring-loaded | wedge 14 into the groove of the core. Then the shaft 18 of the core 5 is rigidly clamped. Upon a command from the remote control 2, the electromagnet 15 is turned off and its measles draws the spring loaded wedge 14 out of the slot of the core. Then, the actuator 10 is turned on, which rotates the holder 8 of the tool 9. At the same time, the actuator 6 moves the slider 3,

final processing of all grooves core 5.
