Abstract

PURPOSE:To economize manhour by form a pressurized-fluid feeding hole opened onto the workpiece installation surface of a working base and installing a pump apparatus for pressurizing and feeding the fluid. CONSTITUTION:An opened port 3 is formed in distribution over the whole part, onto the workpiece installation surface of a working base, and a hole 4 for the communication to each opened port 3 is formed inside the working base. Each opened port 3 is formed into tapered form having the thinner top edge, and a ball 6 is fitted so as to project at the tapered opened port. In the state where the ball 6 is fitted in projection, the opened port 3 is closed, and the pressurized liquid which acts onto the communication hole 4 is the directions of arrow does not flow out. When a workpiece 2 is set onto the working base 1, the ball 6 set under the workpiece 2 is lowered by pressure, and a gap is formed at the opened port 3, and the pressurized liquid supplied by a pump 10 jets-out. Then, the workpiece 2 is floated-up by the liquid jetted-out from each opened port 3, and the friction is reduced, and the workpiece 2 can be transferred very easily.

Description

[Detailed Description of the Invention] This item is used as an addition for attaching crops to machine tools, etc.;
Concerning improvements.

[Additional] It is not easy to remove or remove the crop from the two ICs, or to fix the IC in the C position. In particular, in one crop of a person's philtrum Ii'l, it is difficult to perform minute positioning control IW even if a brain or the like is used.

The present invention was proposed to improve this J:1, and a pressurizing body supply hole with a gap L1 is provided on the workpiece receiving surface of the processing table, and a fluid is supplied to the supply hole. It is characterized by the use of a pressurized pump device.

The present invention will be explained below with reference to an embodiment of the drawings.

In Figure 1, 1 is a processing table, and 2 is a crop.

Openings 3 are distributed over the entire surface of the workpiece receptacle 11 of the processing table, and holes 4 through which the respective openings 3 communicate are formed inside the processing table. Pressure liquid f is a supply port, 6 is a ball inserted into each opening, 7 is a liquid receiver that surrounds the entire processing table 1, and the working liquid is collected from the drain 1'8 to a storage tank 9.
Returned to Δ. Reference numeral 10 denotes a pressure pump, which is provided in combination with a pressure booster as appropriate, and supplies the working fluid stored in the tank 11j' to the supply port 5 under pressure.

Figure 2 is an enlarged detailed cross-sectional view of the frontage 3. As shown in the figure, each 1711 opening 3 on the workpiece mounting surface of the workbench is formed in a tapered shape, and the ball 6 protrudes from this taper space 1''. One doctor is inserted. When the bolt 6 protrudes and is fitted, the gap 1-13 is closed, and the pressurized fluid acting in the direction of the arrow in the communication hole 4 does not flow out.

Therefore, when no workpiece is placed on the processing table 1, each opening 3 is closed by the ball 6, and no hydraulic fluid flows out. Therefore, when the workpiece 2 is placed on the machine 1 during machining work, the balls 6 on the workpiece 2 are pressed dry, and a gap is opened between the holes 3 and 3, and the balls 6 are fed from the pump 10. The pressurized liquid will start to gush out. The workpiece 2 floats up due to the liquid ejected from each opening 3, reducing friction and making the workpiece 2 easier to move. It can be operated extremely easily, such as when moving and avoiding detachment.

This makes it easy to take the workpiece onto the processing table (=l) and
Improved positioning accuracy, easy attachment and detachment, and even heavy workpieces can be handled easily. The pump pressure of the hydraulic fluid can be set according to the size, weight, etc. of the workpiece, but it is generally set to apply a pressure of about 50 to 150 kl f/cm2. For example, machining fluid may be used as the working fluid in electric discharge machines, etc., and it is convenient because it can also be used as a machining fluid circulation device. Of course, a fluid such as air can also be used.

The above description has been made with reference to the drawings of one embodiment, and the structure of the frontage, that is, the ball was used to effect the valve action, but any other means may be used.
