Description

The invention relates to a machine tool industry and can be used in aggregate machines and automatic lines.

Known grandmother power, comprising a housing, a spindle with a flywheel mounted on its output shaft, a drive gel yoke electrode and a reducer 1.

However, the grandmother power is not known, shet reduce the level of vibravdy.

The purpose of the invention is to reduce the level of vibrations.

The goal is achieved by the fact that the power head, comprising a housing, a spindle with a flywheel mounted on its output shaft, a drive electric motor and a gearbox, is equipped with a spindle loading system made in the form of a friction clutch connected with a flywheel connected to a linear engine, a control unit of which is connected to the vibration sensor via a reference element.

The drawing shows the proposed grandma force, a general view.

i On the power table 1, a power head is installed, comprising a housing 2 and a spindle 3. The main movement is driven through a chopper 4 from an electric motor 5. A flywheel 6 is mounted on the output shaft of the spindle, interacting through a friction clutch 7 with a linear electric motor 8 of a direct current returning -nost movement. The level of vibrations is estimated from the data of the proximity sensor 9, transmitting the signal to the unit 10

604102

The vibration level is given by the command to the control unit 1; the motor is screwed by the motor, which switches the linear motor on to one or another voltage depending on the magnitude 5 of the vibration amplitude.

Grandma cell works as follows.

To reduce vibrations, a spindle loading system is included. If amplitude

10 vibrations in the zone of sensor 9 exceed the permissible value, unit 10 compares and evaluates the level of vibrations and gives out1 to the linear motor control unit 11, and the latter, through the friction clutch 7, clocks the flywheel 6 through the friction clutch 7, which led to a change in the system mass and, consistently, to exit from the zone of resonant or close to them frequencies. When the amplitudes of vibrations decrease to an acceptable level, the unit for comparing and estimating the level of vibrations shuts off the linear signal of the motor until the next increase in the level of vibrations due to a change in the allowance or for other reasons. The amount of load activated depends on the amplitude of vibrations.

Reducing the level of vibrations with the help of the proposed power headstock increases the utilization rate of the automated equipment, as it prevents the shutdown of aggregate machines and automagic lines to combat vibrations and prevents the tool / instrument from breaking, while reducing the number of rejected pieces. which loses metal consumption and makes production more economical.
