Abstract

This invention relates to a handheld mechanized tool. The purpose of the invention is to increase efficiency. When the actuator 2 is turned on, its rotation through the central gear wheel 3 with external teeth, satellites 7, the central gear wheel 4 with internal teeth is transmitted to the output shaft 5 and then through the elastic-damping coupling 13, the drive shaft 12 to the exciter 8 rotary oscillations, which starts to accelerate and generates a symmetrical vibration moment on the tightened threaded joint. At this time, the middle two-sided coupling half 18, made in the form of a flywheel and connected with the leading half coupling 16 connected to the carrier 6, is accelerated. When kinematic energy is accumulated, the middle two-sided half coupling 18 is switched by the control system 15 and engages with the driven half coupling 17. This accumulated middle double coupling half 18 kinematic energy through the driven coupling half 17, the elastic damping coupling 13, the housing 9 of the rotary vibration emitter 8 and the spindle 11 is transferred to the tightened threaded joint e. In the process of tightening the threaded connection, by repeatedly switching the middle two-way coupling half 18, a repeated additional transmission of torque to the tightenable threaded connection is carried out. 1 il.

The invention relates to a portable handheld mechanized tool, can be used in various industries in tightening threaded connections, and is an improved invention according to the author. Mg 795927.

The purpose of the invention is to increase efficiency by introducing additional rotating mass.

The drawing shows a schematic diagram of an electric vibrating wrench.

The electric vibrating wrench includes a housing 1, a drive 2 located therein, a differential gear connected with the latter, including central gears 3 and 4 with outer and inner teeth connected to the drive 2 and the output shaft 5, respectively, drove 6 with satellites for rotation: and 7. In case 1, an exciter 8 rotational oscillator is mounted for rotation; including housing 9 with unbalanced shafts 10 placed in it, spindle 11 mounted on housing 9 and drive shaft 12 connected kinematically to unbalance shafts 10. Drive shaft 12 is connected to output shaft 5 through an elastic-damped clutch 13. There is unlocked 1 housing also an elastic-damping clutch 14 connected to the housing 9 of the driver 8 rotary oscillations, a two-way controlled clutch with the control system 15, including a driving coupling half 16 fixed on the carrier 6 of the differential gear, driven half coupling 17 fixed to in the input link of the elastic coupling 14, located between the master 16 and 17 semi-couplings and connected to the control system 15, an average half-span Ryu semi-coupling 18, made in the form of a flywheel and intended for periodic interaction either with the leading .16 or with the driven 17 coupling halves.

The electric vibration wrench operates in the following manner.

When the drive 2 is started up, the central gear 3 begins to rotate with the outer and differential gear teeth. Further, the rotation is transmitted through the satellites 7 to the central gear wheel 4 with internal mm teeth and the output shaft 5 11 through the elastic-damping clutch 13 to the drive shaft 12 of the driver 8 rotary oscillations. The acceleration of the driver 8 rotational oscillations begins. At that, using the control system 15, the middle two-sided coupling half 18c is connected with the leading half coupling 16 rigidly connected with the carrier 6. Thus, simultaneously with the acceleration of the driver 8, the rotary oscillations start

Acceleration of the middle double-half coupling 18, made in the form of a flywheel. After a certain time interval, determined by the control system 15, the middle two-side coupling half 18 is switched, which begins to interact with the driven half coupling 17 connected through the elastic-damping coupling 14 with the housing 9 of the exciter 8 rotational oscillations. At this moment, the medium double half coupling 5 has a significant supply of kinetic energy, which is transmitted to the housing 9 of the driver 8 rotary oscillations and then through the spindle 11 to the threaded joint, which is already affected by the symmetrical vibration moment generated by the driver 8 rotary oscillations. The process of tightening or unscrewing the threaded connection occurs. Depending on the setting (or

5 programs) of the control system 15 during the tightening of the threaded joint, the connection between the driven coupling half 17 and the middle two-way coupling half 18 may occur, in which, when interacting with the driving half coupling 16, kinetic energy is accumulated, which upon subsequent switching of the middle two-coupling half 18 the driven half coupling 17, the elastic-5 damping coupling 13, the housing 9 of the rotary exciter 8 and the spindle 11 is transmitted to the threaded connection. With this, the process of screwing or unscrewing the screw connection will continue. The cycle of kinetic energy transfer from the middle two-sided coupling half 18 to the threaded joint can be repeated many times, depending on the program of the control system 15 of the two-way controlled coupling.
