Description

A device for milling keyways grooved on a rotating shaft with a worm spindle with a worm gear and a screw feed is proposed to be equipped with a drive pulley coupled with another stepped pulley, freely attached to the shaft and suspended from the ceiling or suspension, from which it is suspended from the ceiling, suspended from it, suspended from the ceiling or suspension, from which it was suspended from the ceiling or suspension from which it was suspended from the ceiling or suspension, which was suspended from it, suspended from the ceiling or suspension, which was suspended from it, suspended from the ceiling or suspension, which was attached to it, suspended from the ceiling or suspension, which was suspended from it, suspended from the ceiling or suspension, which was attached to it, suspended from the ceiling or suspension, which was suspended from it, suspended from the ceiling or suspension, which was attached to it, suspended from the ceiling or suspension, which was suspended from it, suspended from the ceiling or suspension, which was attached to it, suspended from the ceiling or suspension, which was suspended from it, suspended from the ceiling or suspension, which was attached to it, suspended from the ceiling or suspension, which was suspended from it, suspended from the ceiling or suspension, which was suspended from it, was suspended from the ceiling or suspension, which was suspended from the ceiling or suspension from which it was suspended. rotation.

In FIG. 1 is a view of the milling spindle mounted on the shaft tool; FIG. 2 is a section along the line G / i in FIG. 1, right view; , figs. 3 is a section of the left part of the device along the axial plane of the screw screw and shaft or line y45 in FIG. one; FIG. 4 is a partial sectional view along the CD line in FIG. .1, right view; FIG. 5 is a partial section along the line EPA of FIG. 1, right view.

On shaft 1 (Fig. 1, 2), frame 2 is reinforced by frame 2, supporting a support with a milling spindle 5. A detachable step pulley b (Fig. 1, 3) mounted on the same left-hand shaft (fig. 1, 3) shaft diameter and suspended from the ceiling or suspension of the transmission.

With pulley b, frictionally coupled pulley 8 (Fig. 1 and 3), mounted on

spindle 9, driving the screw, from which the milling spindle receives rotation. The spindle 9 is pressed to the shaft with a spring bolt to provide the necessary friction clutch, as shown in FIG. 4. When the shaft rotates, the whole machine rotates with it, and the pulley 6 rolls along the stationary pulley 6, and the mill is thus driven. The vertical and horizontal feed to the router is carried out with the help of a fist on the spindle, acting on a crank lever with two dogs 10, P (Fig. 1) for a ratchet on a screw of a horizontal feed and a ratchet 12 vertical. The tool has three speeds and can be used for milling keyways when turning shafts on a lathe.

The subject matter of the invention.

A device for milling keyed grooves on a rotating shaft with the use of a milling spindle rotated by means of a worm gear and receiving in time by means of a screw, characterized in that it is fixed on the shaft to be machined by means of a frame 3 and a bracket 2

the device is equipped with a driving pulley 8, which is in coupling with another stepped pulley b, freely attached to the shaft 1 and suspended from the ceiling or suspension of the transmission, from which rotation is transmitted to it.
