Abstract

PROBLEM TO BE SOLVED: To allow sunk cutting swarf or grinding swarf and fine cutting swarf in cutting oil agent or grinding swarf to be automatically collected using one motor without the collection labor of an operator into a cutting swarf box or a grinding swarf box with a scraping plate attached to a distal end of a bar.SOLUTION: A series of operations of discharging sunk cutting swarf or grinding swarf by an outer scraper 10, simultaneously attracting fine cutting swarf or grinding swarf in a cutting oil agent or a grinding oil agent to a lower surface outer side of a rotor 8 by a magnet 9 provided inside the outer rotor 8 to perform the collection from the inside of a cutting liquid agent or a grinding agent, and performing the conveyance to the outside of a machine by an inner scraper 14 are simultaneously and automatically performed by connected components using one motor 1, and the cutting swarf or the grinding swarf can be thereby collected.

Description

  The present invention is an apparatus for collecting magnetic chips from a machine tool and grinding rods from a grinding machine by settling and magnets.

In conventional machine tool magnetic chip processing equipment (hereinafter referred to as chip processing apparatus), firstly, the cutting fluid discharged from the machine tool and chips flow on a filter provided in the upper part of the tank. Chips were deposited on the filter and the operator collected the chips with a scraper attached to the tip of the rod.
Second, only large chips were collected by a hinge pan type conveyor.
Third, a magnet was installed at the bottom of the conveyor and scraped with a scraper. And fourth, a large scrap was collected with a scraper conveyor and another mechanism with a magnet was added. Some are collected with the combined equipment.
Fifth, a magnetic grinder (hereinafter referred to as a grinder) of a grinding machine is provided with a magnet inside a rotating drum and collects the grinder through a grinding oil in a lower passage of the drum.

In the conventional chip disposal apparatus described above, the apparatus described first has the trouble that an operator frequently collects chips manually.
The second one had a problem that minute chips flow into the cutting fluid storage tank and accumulate. The third device has a problem that the bottom of the conveyor is worn because scraps adhering to the magnet or scraping grinder are scraped out by a scraper.
The 4th apparatus needed the structure of the mechanism which provided another magnet other than the conveyor.
The fifth device has a problem in that a grinding rod accumulates on the bottom of the reservoir because the reservoir is provided before the grinding oil and the grinding rod come into contact with the drum containing the magnet. In addition, there is a problem that the drum and the scraper are worn away in order to scrape off the grinding rod adhering to the drum.

  The present invention is intended to solve the problems of such a conventional configuration. A large chip or a grinding wrinkle is settled and scraped out by an outer scraper, and a minute amount in a cutting fluid or a grinding fluid is obtained. Chips or grinding rods are magnets installed inside the rotor up to the cutting fluid or air away from the grinding fluid, and are attracted to the outside of the lower surface of the outer rotor and fall to the bottom of the main body in air without magnets. The purpose of this is to discharge to the outside with an internal scraper provided on the lower surface of the rotor.

  The machine enters the machine together with cutting fluid from the machine tool, or grinding grinder from the grinding machine together with grinding fluid through the flow path from the inlet, and large chips or grinding rod settles. Accumulate at the bottom of the device. The minute chips or grinding rods are adsorbed and removed by a magnet when floating in the cutting fluid or the grinding fluid and flowing into the storage tank from the slit provided at the bottom of the apparatus.

  The main body of the apparatus is circular and inclined, and the inner rotor is rotated by a motor with a reduction gear (hereinafter referred to as a motor), and the outer rotor is rotated by a connecting bar. An outer scraper and an inner scraper are provided on the outer rotor, and the settled chips or grinding rods are discharged. The outer rotor is made of stainless steel, the magnet is fixed to the main body side without contact inside, and has the function of adsorbing a small chip or grinding rod on the outer surface of the outer rotor and discharging it by rotation. Yes.

  As described above, the chip or grinding rod processing apparatus of the present invention eliminates the labor of the operator collecting the chip or the grinding rod box into the chip box or the grinding rod box with a scraper attached to the tip of the rod. Moreover, the chip | tip which settled with one motor, or the grinding | polishing chip | tip and the fine chip | tip in a cutting fluid, or a grinding | polishing grapple can be collect | recovered automatically.

  1 is a cross-sectional view of a chip or grinding wrinkle processing apparatus showing an embodiment of the present invention.   It is the same top view.   It is the sectional view on the AA line in FIG.   FIG. 2 is a detailed view of part B in FIG. 1.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to FIGS.

In the figure, reference numeral 1 denotes a motor, which is attached to an upper cover 3 of a circular inclined main body 2.
A shaft 4 is connected to the motor and is rotated by a bearing 5 provided on the upper cover of the main body and the lower part of the main body.

  The shaft is connected to the outer rotor 8 by an inner rotor 6 and a connecting bar 7.

  The outer rotor is made of stainless steel, and the magnet 9 is not in contact with the rotor on the inner side, and is provided on the main body side up to the place where there is no cutting oil or grinding oil. The minute chips or grinding rods are adsorbed to the outside of the lower surface of the rotor and fall to the bottom of the main body where there is no magnet in the air away from the surface of the cutting fluid or grinding fluid by rotation.

  An outer scraper 10 is attached to the outer rotor, and chips or grinding rods flowing together with the cutting fluid or the grinding fluid from the inlet 11 of the present apparatus settle on the inclined bottom portion of the main body, and the discharge port 12 is rotated by rotation. The scraps are collected until they are collected or collected in the grinding rod recovery box 13.

An inner scraper 14 is provided outside the lower surface of the outer rotor, and the cutting fluid or fine chips in the grinding fluid or the grinding rod is adsorbed to the lower surface of the rotor and conveyed to the place where the magnet is located, A small chip that falls to the bottom of the main body from a place where there is no magnet or a grinding rod is conveyed to the discharge port by rotation. In addition, the scraper is scraped together when the outer scraper moves to the center side of the tilted main body in the course of carrying out the chips or the grinding rod.
In the above components, when the cutting fluid or grinding fluid passes through the slit 15, the fine chips or the fine grinding rods are removed by the magnet and purified, and flow into the cutting fluid or grinding fluid storage tank 16.
