SU982993A1 - Vibration drive of cicular motion - Google Patents

Description

The invention relates to vibrational transport and can be used in the machine tool industry, for example, in vibratory loading devices.

Vibro-circular movements are known, which contain a base, an upper traverse, obliquely arranged suspensions in the form of one or several flat pruchsins, the ends of which are rigidly fixed on the base and the traverse, and an electromagnet 1.

The disadvantage of the well-known technical reyuny is a large adjustment period for the near-resonant mode, since it is necessary to manufacture a large set of additional strings of different thickness.

The closest technical solution to the invention is a circular vibration actuator including a base with grooves connected to a cross-bar by inclined spring packages, which are fixed rigidly on the cross-bar, and on the base are adjusting nodes made of moving and non-subshaped parts, and an electromagnet 2J.

A disadvantage of the known vibratory drive is the complexity of the setup period and the near-resonant mode. ; The purpose of the invention is to simplify the adjustment of the vibrating circular drive to work in near-resonant mode, as well as changing the direction of oscillation .10

The above goal is achieved by the fact that in a vibrating actuator of a circular motion, including a base with grooves, connected to a traverse, inclined pruijin packages, which are on the traverse

15 are fixed rigidly, and on the basis of adjustment nodes made of moving and fixed parts, and an electromagnet, only one of the inclined springs of the package is rigidly fixed

20 with the fixed part of the adjustment unit, and the movable part is made in the form of a plate with a spacing 1 screw with the possibility of supporting the screw head on the lateral surface of the base groove.

In addition, the base is equipped with wedges, installed in the base grooves with the possibility of their permutation and made with an apex angle equal to twice the angle of 30 on the spring packages.

The drawing schematically shows a circular drive motion.

The vibrodrive consists of the base 1, resting on the shock absorbers 2, Traverse 3, inclined packages of springs 4, connecting the Eldiz base and traverse in several places along the periphery. The attachments of the springs 4 on the traverse 3 are rigidly fixed, and on the base 1 they are fixed with urang / w adjustment, made of fixed 5 and SUB-BET7. B parts. Inclined packages of springs 4 are assembled from a set of several springs 7 with gaskets 8, and only one of them is rigidly fixed on the base by the fixed part 5 of the adjustment assembly. The movable part 6 of the adjustment unit is made of a strip 9 with a spacer screw 10, the head of which rests on the side surface 11 of the groove 12 of the base 1 on one side and on the spherical washer 13 on the other. On the base 1 /, wedges 14 are installed, which are made with a vertex angle equal to twice the angle of inclination of the spring packages and can be swapped with an emphasis on any of their side surfaces. On the traverse 3 is fixed working body 15.

Vibro works as follows.

Depending on the moment of inertia and the mass of the working body 15 installed on the vibro-drive, the working length of the inclined packages of the springs 4 is selected, based on the fact that the vibrational frequency of the vibrating-drive is close to the frequency of the forced vibrations, i.e. okoro resonance. The working length of the bundles of springs 4 is adjusted by moving the movable parts of the adjustment along the spring, zinc 7 along the supporting inclined surface A of the groove 12 of the base 1. In order to move the moving parts b free from (partially sliding) the spacer screw 10, the bar 9 is moved together with the gaskets 8 and the spherical ball 13 into the desired position and re-fastened with a spacer screw 10. In this case, the rigid fixing of one spring from the bag (for example, the extreme one) to the base prevents the displacement of the centers of mass of the drive during adjustment, facilitating Preserve original nalashchki.

The preservation during the readjustment of precise directional oscillations of the working member 15 along a helical line ensures the implementation of stable vibratory movement of parts loaded into the working member.

If it is necessary to change the direction of vibrational transportation of 1СЛИН 14, which can be installed in two positions, leaning on the surface B of base 1, or can be rearranged during readjustment with an emphasis on the surface A of base 1.

The vibrodrive eliminates the possibility of skysgeul fusion, changes the directions of the vibratory displacement and provides a smooth, continuous

variation of oscillation parameters.
