Description

The invention relates to mechanical engineering and can be used to remove drainage chips when machining parts from metallic magnetizable materials on machine tools.

The purpose of the invention is to automate the chip removal process.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. one.

A device for removing waste chips contains a drum 1, on the outer surface of which grooves 2 are formed, forming petals 3, the outer surface of the drum being made with a taper angle varying depending on the part material being processed, i.e. the angle of friction between the drum material 1 and the workpiece material. The drum 1 is mounted on the drive shaft 4 and is kinematically connected with it by means of a torque coupling 5.

On the drum 1, the sleeve 6 is placed with the possibility of axial movement, provided with an annular groove on the periphery, designed to interact with the fork 7, which is rigidly mounted on a support (not shown).

Parallel to the axis of the drive shaft, an axis 8 is fixed, on which a gear sector 9 is placed with the possibility of angular rotation, equipped with a lever 10, on the end of which an electromagnet 1 is fixed. The device is placed on a lathe, in the cartridges of which a part 12 is machined.

The device works as follows. At the initial moment, the lever 10 is in the lower position so that its electromagnet 11 is ready to grip the end of the forming chips 14, and the sleeve 6 with the plug 7 occupies the rightmost position.

During the machining process of the part, the electromagnet 11 captures the end of the forming chips 14 and, turning with the lever 10, passes it through the slots 2 of the drum 1,

About the transition to the top position and off. In this case, the drive shaft 4 is turned on, transmitting through the torque coupling 5 a rotation to the drum 1, which with its petals 3 captures the chips 14 and winds

 on its surface. At the same time, the fork 7, rigidly seated on the support of the machine, moves to the left along the axis of the part with a predetermined longitudinal feed and moves the sleeve 6.

After completion of processing occurs

The movement of the caliper and, with it, the forks 7 and the bushings 6 to the extreme right, in view of which the chips formed in the form of a tube-helix, are displaced by the bushings 6 with the petals of the drum 1 and dumped into a special tray. In order to facilitate the gathering

shavings 14 drum 1 is made conical with an angle of at least the angle of friction between the drum and the chips.

When installing another billet, the lever 10 occupies the lower initial position and enters into operation at the moment of the start of formation of the chip 14.

The use of the proposed technical solution allows to increase the processing efficiency by reducing the auxiliary time and automating the process of chip removal and removal.
