Description

In the proposed machine, the working tools are fixed on rods receiving reciprocating movement from the levers controlled by the fist groove of the disk fastened to the driving pulley, transmitting the movement to the gear to report the reciprocating movement of the machine table and feeding rods carrying the working tools ..

In FIG. 1 is a front view of the machine; FIG. 2 is a top view thereof; FIG. 3 and 4 view of the individual connections of the machine.

In the machine bed, a vertical rod 20 is installed, equipped with a table 2 with dividers 16 mounted on its upper end and a clamping device for machined wheel hubs 1. The rod 20 is mounted in the cylindrical cavity of the stanchion with the possibility of alternating in the vertical direction a pulley 4, a disk 5 and a gear wheel 22 fastened together with a common bushing. The disk 5 is provided with a fist groove 6, in which the rollers of the two levers 7-7 retarded, are located

mi 8-8, mounted on the rods 15-15 freely located in the horizontal bearings of the machine bed. The ends of the levers 7-7 are hingedly fastened to the rods 9-9, mounted opposite each other along a common geometrical axis and bearing 10-10-10 bits fixed at their ends, with the rods 9-9 positioned in bearings with axial movement. Coupled with the pulley 4, the gear wheel 22 through gears 11-11, 17-17, 21-21 transmits rotation to the rollers 12, at the ends of which, facing the rod 20 of the table 2 of the machine, are fixed fists 13-13 that are in contact with the fixed on the rod with 20 fingers. From rollers 12–12, retreated and fastened to them by means of eccentrics, ti 18-18 with dogs at the ends. The pawns are engaged with ratchets 14-14, the sleeves of which are provided with an internal thread and act as nuts for the screwed ends of the rods 15-15.

When using the machine designed for processing, the hub is fixed

on table 2 of the machine and pulley 4 rotation is reported. Due to the impact of the fist grooves 6 rotating with pulley 4 of the disc 5 on the rollers of the levers 7-1, the latter inform the rods 9-9 and the 10-10-10 fasteners attached to them to return to the bearings in the bearings holding them. Rotating together with the pulley 4 and the disk 5, the gear 22, through a gear 11-11, 17-17, 21-21 informs the rotation to the rollers 12-12, the fists 13-13 of which, acting on the fingers of the rod 20, inform the latter, and together with him and schicholik 2 with the processed hub 1, returnable movement in the vertical direction. The 12-12 tons of gigs 18-18 connected to the rollers fixed at their ends inform the intermittent movement of the ratchets 14-14, the bushings of which act as nuts for the rods 15-15, according to them the axial movement. Slider 15-15, moving in the horizontal direction, carries along the levers 7-7 and rods 9-9, thus making an intermittent feed of bits 10-10. Thus, the bit 10-10, getting a single turn of the rollers 12-12 interleave {back and forth, and in addition feed, select the nests

moving in motion with a table 2 machine wheel hub.

The subject of the patent.

A slotting machine for forming nests in the hubs of wooden wheels, characterized by the use of 10 rods 9 located against each other along a common geometrical axis of the chisel-bearing axes, which are reciprocated from the levers 7 controlled by the fist groove 6 in the disk 5 receiving rotation from the drive pulley 4, and having axes 8c rods x 15, moved, the purpose of feeding bits, longitudinally by cutting on each of them, and the nuts in the sleeve of the other of the ratchets 14, automatically received by moving and through t 18 and gears 22-11-- 1L-21-12 from pulley 4 and manually from handle 19, in the Kraków device, the machined sleeve is fixed on a table 2 equipped with a dividing wheel 16, receiving upward from jammed n1 wasps x 12, fists 13 and down-under the action of its own weight.
