Description

Technical Field

[0001] The invention relates to the technical field of machine tool chip removal, in particular to a machine tool chip removal device. Background Art

[0002] Machine tools are used to process various workpieces and parts to manufacture industrial products such as machines. They are also called industrial mother machines and have an irreplaceable position in mechanical processing. Common machine tools include metal cutting machine tools, forging machine tools, etc. During processing, a large amount of iron chips will be generated due to the cutting of the tool. Therefore, machine tools need to be equipped with chip removal devices to clean and recycle the iron chips. Since the sizes of iron chips vary during processing, sometimes the iron dropped from metal workpieces will be in a rolled shape, which affects the subsequent chip removal. At the same time, a large amount of coolant will be used when cutting bevels. Some iron chips are too small and will be filtered down with the coolant, which has a negative effect on the recycling of the coolant. In addition, the filter structure is prone to clogging after a period of use. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention discloses a chip removal device for a machine tool, and the technical scheme adopted is that it includes a chip removal box, a base, a coolant discharge channel, an iron chip discharge outlet, a conveyor belt, a filter plate cleaning structure, an inclined filter plate, filter holes, a filter hole cleaning mechanism, a bottom scraper, a left motor, a side wall groove of the coolant discharge channel, a bottom lead screw, a bottom guide shaft and a T-shaped scraper.

A conveyor belt is installed on the outer top surface of the coolant discharge channel through a frame, and the conveyor belt is located below the iron chip discharge outlet. After the iron chips are discharged from the iron chip discharge outlet, they enter the conveyor belt for transfer. An inclined filter plate is fixedly installed in the chip removal box, and a plurality of filter holes are distributed on the plate. The inclined filter plate is connected to the iron chip discharge outlet, and the iron chips are discharged from the iron chip discharge outlet under the guidance of the inclined filter plate. The interior of the chip removal box is located at the inclined filter plate. A filter plate cleaning structure is provided above the inclined filter plate, which can clean the upper surface of the inclined filter plate to avoid congestion and accumulation.
