JPH10291160A - Recovering device for grinding liquid in grinding device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the spattering of the grinding liquid to the succeendings, by installing a bottomed sub-tank in a tank with an opening located at a position higher than the liquid level of the tank, and inserting a lower opening of an exhaust tube installed in a grinding device, into the sub-tank. SOLUTION: The grinding liquid (A) supplied to a machining part of a work, flows from a grinding device 1 into a sub-tank 5 from a lower opening part 3 of an exhaust tube 2, through the exhaust tube 2. Since the lower opening part 3 of the exhaust tube 2 is inserted into an intermediate part of the sub-tank 5, the grinding liquid (A) flowing from the lower opening part 3 of the exhaust tube 2 is filled in the sub-tank 5, then overflows from the sub-tank 5 through its outer wall face, and is stored in a tank 4. Since the lower edge of the sub- tank 5 is immersed in grinding liquid 4 stored in the tank 4, the grinding liquid flows down calmly.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for collecting a grinding fluid in a grinding apparatus.

[0002]

2. Description of the Related Art As shown in FIG. 3, for example, a grinding apparatus (1) such as a centerless grinding machine is provided with a discharge pipe (2) for discharging used grinding fluid. Conventionally, the opening end (3) of the discharge pipe (2) simply opens above the tank (4) for collecting the grinding fluid.

[0003]

Therefore, the open end (3)
Since the grinding fluid (A) flowing out drops from the high position to the liquid surface of the tank (4), the grinding fluid (A) is sprayed or misted and scatters around, so that not only the grinding device (1) but also the surroundings The floor surface of the car became wet and slippery, deteriorating the work environment. In addition, the abrasive powder from the grinding stone and the metal chips become muddy,
The sediment deposits on the bottom surface of the tank (4), which makes the disposal work troublesome and causes a failure of the suction pump.

[0004] It is an object of the present invention to provide an apparatus for collecting a grinding fluid which can solve the above problems.

[0005]

According to the present invention, an object of the present invention is to provide a recovery device for recovering used grinding fluid discharged from a grinding device via a discharge pipe into a tank provided near the grinding device. In the inside of the tank, a bottomed sub-tank whose upper end opening is higher than the liquid level in the tank is provided, and in this sub-tank, a lower end opening of a discharge pipe provided in the grinding device is provided. It is solved by inserting.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, the grinding device (1) is provided with a discharge pipe (2) for discharging used grinding fluid (A). Lower end opening (3)
Is inserted up to an intermediate portion in a sub-tank (5) having a bottom which is detachably provided in a tank (4) for collecting a grinding fluid. The upper end opening of the sub tank (5) is located slightly higher than the liquid level in the tank (4).

The upper edge of the side plate of the sub-tank (5) has a tank
A locking piece (7) locked to the upper edge of the side wall (6) of (4) and a handle (8) for attaching and detaching the sub tank (5) are provided. Reference numeral (9) denotes a pump for sucking and circulating the grinding fluid collected in the tank (4).

In the apparatus of the above embodiment, the grinding fluid (A) supplied to the work portion of the work and having completed the functions of lubrication, cooling, cleaning and the like is discharged from the grinding device (1) through the discharge pipe (2). Then, it flows into the sub tank (5) from the lower end opening (3). At this time, the lower end opening (3) of the discharge pipe (2) is connected to the sub tank (5).
The grinding fluid (A) flowing from the lower end opening (3) of the discharge pipe (2) is inserted into the sub tank (5).
After filling the inside, it overflows from the sub-tank (5), flows down the outer wall surface, and is stored in the tank (4). At this time, since the lower end of the sub-tank (5) is immersed in the grinding fluid (4) stored in the tank (4), the grinding fluid flows down gently.

The discharged grinding fluid (A) contains abrasive powder from a grindstone, metal chips, and the like. However, these have much higher specific gravity than the grinding fluid (A). Sub tank
When it flows down into (2), it precipitates and deposits on the bottom. Therefore, when a certain amount is accumulated, it is necessary to dispose of the sediment. In this case, holding the handle (8) removes the sub-tank (2) from the tank (4) and then treats the sediment. I just need.

[0010]

According to the grinding fluid recovery device of the present invention, the grinding fluid discharged from the grinding device once flows into the tank, overflows therefrom, and flows out quietly into the tank.
The grinding fluid does not splash or mist and scatter around, so that the working environment is significantly improved.

Further, impurities such as friction powder contained in the grinding fluid settle at the bottom of the sub-tank, so that they do not flow into the tank, and the clean grinding fluid can be reused.
