As shown, a housing 10 is formed to form a chamber 11 of a predetermined space. On one surface and the other surface of the housing 10 which face each other, a coupling tube 13 and a guide tube 15 communicating with the chamber 11 are formed to protrude to the outside and the inside of the housing 10, respectively, An inlet 17 through which compressed air for launch is introduced is formed.

The launch tube 20 is coupled to the coupling tube 13, and the launch tube 20 includes an object 80 that is launched by the compressed air introduced into the housing 10 through the inlet 17. At this time, the outer circumferential surface of the coupling tube 13 and the inner circumferential surface of the launch tube 20 are contacted and sealed, and the inner circumferential surface of the launch tube 20 and the outer circumferential surface of the object 80 are contacted and sealed. This is to prevent leakage of the compressed air for firing.

The inner circumferential surface of the guide tube 15 is inserted into and contacted with the outer circumferential surface of the cylinder 30, and the first and second inlet / outlet ports 31 and 33 into which the hydraulic pressure flows in and out of one side and the other side of the cylinder 30. ) Is formed. The first inlet / outlet 31 and the second inlet / outlet 33 are formed spaced apart from each other by a predetermined distance. That is, the first inlet / outlet 31 is formed closer to the housing 10 than the second inlet / outlet 33.

Then, one side is provided in the cylinder 30 and the other side is provided with a tong member 40 located in the interior of the housing (10). The tong member 40 is integrally coupled to the object 80 while moving to the second inlet / outlet 33 when the oil pressure is introduced into the first inlet / outlet 31, and the oil pressure into the second inlet / outlet 33. When the inflow is moved to the first inlet / discharge port 31 side separated from the object 80, which will be described in detail.

The tong member 40 has a linear motion plate 41, a connecting rod 43, and a tong part 45.

The linear motion plate 41 is positioned inside the cylinder 30 between the first inlet / outlet 31 and the second inlet / outlet 33 to contact and seal the inner circumferential surface of the cylinder 30. Thus, when the oil pressure flows into the first inflow / outlet 31, it moves to the second inflow / outlet 33, and when the oil pressure flows into the second inflow / outlet 33, it moves to the first inflow / outlet 31. do.

One end of the connecting rod 43 is coupled to the linear motion plate 41 and the other end is located inside the guide tube 15 to move in the same manner as the linear motion plate 41. At this time, the diameter of the connecting rod 43 is provided smaller than the diameter of the linear motion plate 41 so that the outer peripheral surface of the connecting rod 43 and the inner peripheral surface of the cylinder 30 do not contact.

The tongs 45 are provided in pairs 46 and 47 facing each other and coupled to the other end of the connecting rod 43. Thus, while moving in the same manner as the connecting rod 43, the inside and the outside of the guide tube 15 is moved in and out, thereby engaging and separating from the object 80. In detail, when the connecting rod 43 moves inwardly of the cylinder 30, each of the tongs 46 and 47 is brought into contact with the inner circumferential surface of the guide tube 15, and is coupled with the object 80 at the same time. When the connecting rod 43 moves to the inside of the housing 10, the pair of tongs 46 and 47 are exposed to the outside of the guide tube 15 to be separated from each other and separated from the object 80 at the same time. .

Semicircular locking grooves 46a and 47a are formed on the inner circumferential surface of the free end of each of the tongs 46 and 47, respectively. That is, when the free ends of each of the tongs 46 and 47 are adjacent, the entire shape of each of the engaging grooves 46a and 47a is circular. In addition, a protrusion 81 is formed on the object 80, and end portions of the protrusion 81 adjacent to the catching grooves 46a and 47a are provided in a shape corresponding to a circular shape formed by the catching grooves 46a and 47a. do. Thus, the tongs 45 and the projections 81 are coupled and separated by the movement of the tongs 45. Reference numeral 19 is a pressure gauge.

The operation of the launch test apparatus using the hydraulic pressure according to the present embodiment configured as described above will be described.

As illustrated in FIG. 1, a tong part 45 is located outside the guide tube 15 and adjacent to the protrusion 81, and the first and second inlet / outlet ports 31 and 33 and the inlet part ( In (17), it is assumed that the state where no oil pressure is introduced is the first state. In this state, when the hydraulic pressure flows into the first inlet / outlet 31, the linear motion plate 41 moves to the second inlet / outlet 33. Then, since the tongs 45 are inserted into the guide tube 15, each of the tongs 46 and 47 is retracted inward. Then, since the projections 81 are caught in the engaging grooves 46a and 47a of each of the tongs 46 and 47, the tongs member 40 and the object 80 are integrally coupled as shown in FIG. 2. do.

In the state as shown in FIG. 2, when the air pressure does not flow into the first inlet / outlet 31 and compressed air flows into the inlet 17, the inside of the chamber 11 becomes a high pressure. After that, when the hydraulic pressure flows into the second inlet / outlet 33, the forceps member 40 is moved to the housing 10 side. Then, the tongs 45 are exposed to the outside of the guide tube 15, whereby each of the tongs 46, 47 are spread out to each other, the state as shown in FIG.

Then, since the tongs 45 and the protrusions 81 are separated, the object 80 is launched to the outside of the launch tube 20 by the pressure inside the chamber 11. When it is necessary to adjust the firing range and the firing speed of the object 80, the pressure inside the chamber 11 may be adjusted while looking at the pressure indicator 19.
Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope described in the claims.
