Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a chip removal device for a lathe that removes chips entangled with a cutting tool, that is, a cutting tool.

[Conventional technology]

In recent years, lathes have been increasingly automated with NC lathes, etc., and with this automation, it has become a problem that chips generated by turning become wrapped around or entangled with the cutting tool, that is, the cutting tool.

Conventionally, not only in normal lathes, but also in automated lathe lines such as NC lathes, operators have occasionally visually detected the entangled state of these chips. If these chips become entangled with the cutting tool, the current situation is that the operator stops the machine, ie, a lathe such as an NC lathe, and removes the entangled chips. Alternatively, a small cylinder or the like is used to scrape off the twisted or entangled chips by the movement of the small cylinder or the like.

[The problem that the idea attempts to solve]

However, in automated lines such as the above-mentioned NC lathes, if chips are wrapped around or entangled with the cutting tool, the turning accuracy or machining accuracy of the workpiece may be extremely deteriorated by these chips, or the workpiece may be damaged. This has caused problems such as damage to the cutting tools. Moreover, in order to remove these chips, the machine, that is, the lathe such as an NC lathe, must be stopped each time, which not only hinders the automation of the equipment, but also requires human labor, which is not desirable. It was something I didn't have.

The purpose of this invention is to solve the above-mentioned problems.In the automation of machines such as NC lathes, it is possible to automatically remove the chips generated by turning, which are obstacles, and improve the machining accuracy of workpieces due to chips. It is an object of the present invention to provide a chip removal device for a lathe, which is characterized in that it does not cause defects and also prevents damage to cutting tools and workpieces due to chips.

[Means to solve the problem]

In order to achieve the above object, this invention is constructed as follows. That is, this invention includes a tool rest attached to a slide base, a lathe chuck to which a workpiece is removably attached, a cutter fixed to the tool rest for turning the workpiece attached to the lathe chuck, and the tool rest. a loading device that moves through a space between the tool post and the lathe chuck in a state in which the tool rest is retracted from the lathe chuck, and that attaches a workpiece to the lathe chuck; The present invention relates to a chip removing device for a lathe, characterized in that it has a brush for scraping off chips entangled with the cutting tool by coming into contact with the cutting tool during movement.

Further, the chip removal device for this lathe includes a brush that is disposed in a lateral region of the lathe chuck and is used to scrape off chips entangled with the cutting tool.

Further, in this chip removal device for a lathe, the brush is made of a soft material such as a nylon brush.

[Effect]

This invention is constructed as described above and operates as follows. That is, the chip removing device for a lathe according to this invention removes chips entangled with a cutting tool fixed to a tool post attached to a slide base between the tool post and the lathe chuck in a state where the tool post is retracted from the lathe chuck. Since the structure is configured so that the brush attached to the loading device that moves through the space between the parts is scraped off, the material that has become wrapped around or tangled with the cutting tool is scraped off each time the loading device is moved to attach a workpiece to the lathe chuck. Chips can be easily scraped off with the brush.

Furthermore, when a brush is arranged in the lateral area of the lathe chuck, the cutting tools mounted in parallel on the slide base move back and forth and left and right with respect to the lathe chuck, so each time the brush moves, the cutting tool The chips wrapped around or entangled with the brush come into contact with the brush, and the chips are scraped off from the cutting tool.

Further, since the brush is made of a soft material such as a nylon brush, even if the cutting tool comes into contact with the brush, the cutting tool will not be damaged.

The chip removal device for a lathe according to this invention is constructed as described above, and has the following effects. That is, the chip removal device in this lathe includes a tool rest attached to a slide base, a lathe chuck to which a workpiece is removably attached, and a tool rest fixed to the tool rest for turning the workpiece attached to the lathe chuck. A cutting tool, a loading device that moves through a space between the tool rest and the lathe chuck with the tool rest retracted from the lathe chuck, and attaches a workpiece to the lathe chuck, and the loading device Since it has a brush that comes into contact with the cutting tool and scrapes off chips entangled with the cutting tool when it is mounted and moved relative to the lathe chuck, the movement of the machine such as an NC lathe, that is, every time a workpiece is mounted or removed from the lathe chuck, is provided. In addition, the brush inevitably comes into contact with the cutting chips that are wrapped around or entangled with the cutting tool, and the cutting chips are easily scraped off from the cutting tool by the brush.

Moreover, the brush has a simple structure that can be simply attached to an existing machine such as an NC lathe, that is, the loading device, and can easily remove chips without using a special removal device equipped with operating means. You can definitely scrape it off.

Therefore, the workpiece, cutter, etc. will not be damaged by chips, the turning accuracy of the workpiece will not be reduced by chips, and the cost of the equipment itself can be reduced. . In addition, since the chips do not remain wrapped around or tangled with the cutting tool, the chips do not interfere with the automation of machines such as NC lathes.

Further, in the case where a brush is disposed in the lateral region of the lathe chuck, the brushes that are mounted on the slide base in parallel may wrap around or become entangled with the cutter whenever the cutter tools mounted in parallel on the slide base move relative to the lathe chuck. Chips inevitably come into contact with said brush,
The chips are easily and reliably scraped off from the cutting tool.

Further, since the brush is made of a soft material such as a nylon brush, even if the cutting tool comes into contact with the brush, the cutting tool will not be damaged. By placing the brush around the lathe chuck or near the cutting tool, the brush can provide various effects such as preventing cutting fluid from scattering.
