Abstract

Provided is a device discharging chips, which is configured to allow smooth transfer because it is possible to absorb transformation of connecting pins due to a force generated while chain driven belts are operating as well as smoothly discharging a coolant and chips.

Claims

1. A device for discharging chips, comprising:

a plurality of interlinked belt segments coupled together to form a segmented belt;

a plurality of chain links that are coupled together to form chains at opposing ends of the belt segments;

a plurality of belt guides disposed between the chain links and the belt segments at opposing ends of the belt segments and having a height greater than a height of the chain links;

a plurality of chip supporting plates disposed on respective belt segments; and

a plurality of connecting pins that run through holes in the chain links, the belt guides and the belt segments and provide jointed movement of the belt segments in a width direction to discharge the chips,

wherein each chip supporting plate comprises;

at least one coolant discharging groove disposed at a base portion;

an upper surface facing away from the belt segments, the upper surface having a tooth-shaped profile including a series of peaks and valleys; and

a jagged body shape oriented in the width direction comprising a series of peaks and valleys.

2. The device of claim 1, wherein each chain guide includes a pair of through holes formed with a specific interval at a bottom part and into which the connecting pin is inserted, wherein one of the pair of the through holes has a long-hole shape having an interval in which the connecting pin inserted to the transfer direction is movable within a specific range.

3. The device of claim 1, wherein the at least one coolant discharging groove includes a plurality of coolant discharging grooves disposed at valleys of the jagged body.

4. The device of claim 1, wherein the at least one coolant discharging groove includes a plurality of coolant discharging grooves disposed at peaks and valleys of the jagged body.

5. The device of claim 1, wherein the chip supporting plates span a majority of a width of the belt segments.

6. The device of claim 1, wherein a number of the peaks and valleys of the upper surface of the chip supporting plates is greater than a number of the peaks and valleys of the jagged profile.

7. The device of claim 1, wherein at least two belt segments without any chip supporting plates are disposed between each belt segment on which a chip supporting plate is disposed.

8. The device of claim 1, wherein the peaks and valleys of the jagged body shape are defined by a series of linear segments, and each peak is connected to each valley through a single linear segment.
