Description

one

Known vibration dampers for metal cutting flocks, which are installed between the tool holder and the carriage of the machine and contain interacting with the part of the roller in combination with an adjustable damper, for example, in the form of a package of Belleville springs.

The described vibration damper differs from the known ones in that it is made in the form of a lever, one end of which is hingedly connected to the tool holder and equipped with a roller interacting with the part, and the other end is fixed by means of an adjustable damper fixed to the cross support carriage.

This increases the effectiveness of the slaking.

FIG. 1 schematically shows a vibration damper in the working position on the tailstock side; pas figs. 2 is a section along A-A in FIG. one; pas figs. 3 is a view along arrow B in FIG. 2

The vibration damper contains a lever 1 connected by an axis 2 with a holder 3, a roller 4 interacting with a part, mounted with an axis 5 in the groove of the lever 1, a threaded rod 6 mounted freely on the end of the lever. On the rod 6, the damping elements 9 are mounted on both sides of the lever by means of adjusting nuts 7 and fixing nuts 8. In the working position, the rod 6 is fixedly connected to the cross support carriage by means of wrench clamps 10 and

11 (see FIG. 2) mounted on a single assembled screw 12 provided with right and left cuts. The sections 13 and the cover 14 form a lock which is fixedly connected through the base 15 to the cross support carriage and into which is mounted a screw 12 driven from the handle 16.

Vibration damper works as follows. In the initial position, the lever 1 vibration damper together with the damper overturned on the toolholder.

When working, the vibration damper lever is lowered onto the workpiece so that with it

in contact with the roller vibration damper. The knob 16 of the locking mechanism locks the rod 6 of the damper. In this case, the vibration damper lever is loaded only with its own weight. The locking mechanism is designed so that

prevent the vibration damper lever from moving in a vertical direction. Thus, the vibration damper lever is in such a state that its end can only be moved in vertical direction.

on the amount of deformation of the deforming elements 9, which can be adjusted with the help of nuts 7. As the damping elements can be used cup springs or rubber gaskets.

The effectiveness of vibration control is determined by

by the ratio K -, where / i and / 2-distance from

The axle of the hinge of the lever linking the lever with the tool holder to the damper axis and to the axis of the roller, which interacts with the part.

Subject invention

Vibration damper to a cutting machine, such as a lathe, which is installed between the tool holder and the carriage

four

machine contains a roller interacting with the part in combination with an adjustable damper, for example, in the form of a disk spring package, characterized in that, in order to increase the efficiency of vibration control, it is designed as a lever, one end of which is hinged to the tool holder and equipped with a roller interacting with the part, and the other end with a damper is fixed on the transverse carriage of the sunnort.
