Seal it so that cutting water and chips do not splash outside. When the cutting fluid tank is taken in and out for cleaning or the like, the air pressure is released, the flexible tube is contracted to return it to its original shape, and a gap δ is created, and then the tank is taken in and out.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a seal structure of a chip and cutting fluid treatment device installed in a machine tool of the machine.

[0002]

[Prior Art]

 Conventionally, the cutting fluid tank used for machine tools needs to clean the medello accumulated in the tank and replace the cutting fluid at regular intervals. Therefore, as shown in FIG. 4, for example, the cutting fluid tank 101 incorporating the chip conveyor 104 has a caster 102 on the lower surface and is movable, so that it does not interfere with the lower surface of the fixed cover 103 of the machine when moving. It is usually installed with a gap δ.

[0003]

[Problems to be solved by the device]

 The method of installing the cutting fluid tank with the gap δ according to the conventional technique has a problem that the cutting fluid splashes from the gap or the cutting fluid jumps out to contaminate the floor surface. The present invention has been made in view of the above problems of the conventional technology, and its purpose is to easily take in and out when cleaning the tank and prevent cutting fluid and cutting chips from leaking out from the gap. An object of the present invention is to provide a sealing structure for a chip and cutting fluid treatment device.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the sealing structure of the chip and cutting fluid treatment device in the present invention is designed to cut under the bottom opening of the fixed cover for cutting fluid and cutting fluid provided inside the machine tool. In a chip and cutting fluid treatment device that can be loaded and unloaded with a fluid tank, a flexible tube is provided around the bottom opening of the fixed cover with a gap between the fluid tank and the top surface of the cutting fluid tank. The flexible tube is provided with a fluid pressure supply means for expanding the flexible tube as needed to close and seal the gap.

[0005]

[Action]

 When the machine is in operation, fluid pressure is supplied to the flexible tube at the lower end of the fixed cover to expand it and close the gap with the upper surface of the cutting fluid tank to seal it so that cutting fluid and cutting chips do not leak outside. When the cutting fluid tank is taken in and out for cleaning, release the fluid pressure of the flexible tube to shrink it and make a gap with the top surface of the cutting fluid tank before taking it in and out.

[0006]

【Example】

 Examples will be described with reference to FIGS. 1 to 3. A pocket 1a is provided downward around the bottom opening of the fixed cover 1 which is provided around the cutting area of the machine and guides chips and cutting fluid onto the cutting fluid tank described later. A cutting fluid tank 2 having casters 3 is installed under the fixed cover 1 so that it can be taken in and out. A gap required for taking in and out is provided between the lower end surface of the fixed cover 1 and the edge plate 2a on the upper surface of the cutting fluid tank 2. δ is provided. A chip conveyor 4 is installed in the cutting fluid tank 2 via a mounting base, and cutting chips and cutting fluid falling from the bottom opening of the fixed cover 1 fall on the conveyor 5 on which the conveyor 4 moves. Only the powder is sent to the outside, and the cutting fluid collects at the bottom of the tank.

A flexible tube 6 is provided in the pocket 1a of the fixed cover 1 so that the upper surface thereof is stuck by an adhesive or the like so that the flexible tube 6 can be completely accommodated. The packing 7 is attached. Further, the flexible tube 6 is provided with an air intake port 6a at a position where it does not interfere with the insertion and removal of the cutting fluid tank. From this air intake port 6a, the air source P, the filter 8, the regulator 9, and the switching. Air pressure is supplied through the valve 11. When air pressure is supplied to the flexible tube 6, the flexible tube housed in the pocket 1a as shown in FIG. 3 expands and protrudes downward as shown in FIG. The edge plate 2a on the upper surface of the cutting fluid tank is abutted to close the gap for sealing.

Next, the operation of this embodiment will be described. While the machine is in operation, the switching valve 11 is constantly switched to the a position, whereby the air pressure sent from the air source P through the filter 8 and the regulator 9 is supplied to the flexible tube 6 and inflated, so that the lower surface The attached rubber packing 7 abuts the edge plate 2a on the upper surface of the cutting fluid tank 2 to close the gap δ for sealing. Therefore, the cutting fluid and chips that fall are blocked by this seal and do not scatter on the floor. Next, when pulling out the cutting fluid tank 2 for cleaning or the like, first, the solenoid valve 11 is switched to the b position, the air intake 6a of the flexible tube 6 is communicated with the atmosphere to release the air pressure, and the tube 6 is removed. After shrinking and returning to the original shape and being stored in the pocket 1a to form the gap δ, the cutting fluid tank is carried out to a position where there is no hindrance to the work. The method of inflating the flexible tube 6 is not limited to the one in which the air pressure is constantly supplied from the air source P through the switching valve, and it is used for, for example, a tire of an automobile or a bicycle. It is also possible to install a one-way valve such as an air intake port that is used to seal the air pressure in the flexible tube and to manually perform air bleeding only when the cutting fluid tank is taken in and out.

[0009]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. The flexible tube provided under the fixed cover of this machine is expanded by fluid pressure to close the gap between the fixed cover and the cutting fluid tank and seal it, so cutting fluid and cutting chips are scattered to the outside. The environment inside the factory can be improved, and the cutting fluid tank can be easily taken in and out as usual by creating a gap by releasing the fluid pressure.
