Description

Technical Field

[0001] This utility model relates to the field of high-speed impact cylinder technology, specifically a switching device for simulating a comprehensive launch test. Background Technology

[0002] The simulated launch test facility is an important test device for conducting ground-based simulated launch tests of different types of missiles mounted on rail-launched systems, providing necessary testing methods for the reliability testing of rail-launched systems.

[0003] In actual use, the existing equipment suffers from limited cylinder push-pull force in driving the switch board. When the system operating pressure is high, this increases the friction between the switch board and the blocking flange. When the cylinder's driving force is less than the friction, the cylinder cannot pull the switch board, leading to launch failure. Because the system has multiple interlocking mechanisms, it is necessary to purge the high-pressure gas from the power system and recharge it for testing. Launch failure not only causes economic losses but also reduces work efficiency and may even damage the equipment, which is unacceptable. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a switching device for simulated launch integrated testing, which has the advantages of being more labor-saving and modular, and solves the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a switching device for simulating a comprehensive launch test, comprising a base, an mounting plate fixedly installed on the outer wall of the base, a cylinder, a bearing with a seat, a first fixed slide rail, and a second fixed slide rail respectively installed on the top of the base, a bolt provided on the top of the bearing with a seat, a keyed rotating shaft rotatably connected to the inner wall of the bearing with a seat, a gear two and a gear one respectively installed on the outer wall of the keyed rotating shaft, a sliding seat one slidably connected to the top of the first fixed slide rail, a rack one installed on the top of the first sliding seat, a sliding seat two slidably connected to the top of the second fixed slide rail, a rack two fixedly installed on the top of the second sliding seat, a connector rotatably connected to the telescopic end of the cylinder, a connecting rod two fixedly installed on the outer wall of the rack one, a switch plate provided on the inner wall of the connecting rod two, a locking pin slidably connected to the inner wall of the connecting rod two, a threaded sleeve fixedly installed on the outer wall of the rack two, and a sensor fixedly installed on the top of the cylinder.

[0007] As a preferred technical solution of this utility model: the first gear is located above the first rack, and the first gear meshes with the top of the first rack.

[0008] As a preferred technical solution of this utility model: the number of teeth of the second gear is greater than the number of teeth of the first gear, and the height of the first rack is higher than the height of the second rack.

[0009] As a preferred technical solution of this utility model: the shape of the locking pin is adapted to the inner wall of the connecting rod two and the switch plate, and the thickness of the switch plate is adapted to the inner wall of the connecting rod two.

[0010] As a preferred technical solution of this utility model: the outer wall of the connector away from the cylinder is threaded, and the thread of the outer wall of the connector is adapted to the inner wall thread of the threaded sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The switching device used for simulating a comprehensive launch test, by activating a cylinder, causes the connecting head to move, which in turn causes the connecting rod two and rack two to move, which in turn causes rack two to rotate gear two, which in turn causes the internal keyed rotating shaft to rotate, which in turn causes gear two to rotate gear one, which in turn causes gear one to move the bottom rack one, which in turn causes rack one to move the external connecting rod two, switch plate and locking pin, thereby activating the switch. The gear ratio between gear two and gear one is configured to achieve the purpose of saving effort.

[0013] 2. This switch device used for simulated launch integrated testing allows for the separation of the bearing seat and base by removing bolts, thereby dismantling the bearing seat and allowing the removal of the keyed rotating shaft inside. This enables the replacement of the keyed rotating shaft, gear two, and gear one. Removing the locking pin eliminates the fixing relationship between the switch plate and connecting rod two, allowing for the replacement of the switch plate. Simultaneously, rotating the connector allows it to separate from the threaded sleeve through its threaded connection, enabling the removal of the threaded sleeve and rack two. The modular design of the entire device improves overall maintenance speed and facilitates its use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 A switching device for simulating a launch integrated test includes a base 1, an mounting plate 2 fixedly installed on the outer wall of the base 1, a cylinder 3, a bearing 4 with a seat, a first fixed slide rail 9, and a second fixed slide rail 12 respectively installed on the top of the base 1, a bolt 5 provided on the top of the bearing 4, a keyed rotating shaft 6 rotatably connected to the inner wall of the bearing 4, a second gear 7 and a first gear 8 respectively installed on the outer wall of the keyed rotating shaft 6, and a sliding seat 10 slidably connected to the top of the first fixed slide rail 9, the top of the sliding seat 10... The cylinder 3 is equipped with a rack 11, a sliding seat 13 is slidably connected to the top of the fixed slide rail 12, a rack 14 is fixedly installed on the top of the sliding seat 13, a connector 15 is rotatably connected to the telescopic end of the cylinder 3, a connecting rod 16 is fixedly installed on the outer wall of the rack 11, a switch plate 17 is provided on the inner wall of the connecting rod 16, a locking pin 18 is slidably connected to the inner wall of the connecting rod 16, a threaded sleeve 19 is fixedly installed on the outer wall of the rack 14, and a sensor 20 is fixedly installed on the top of the cylinder 3.

[0022] In the above structure, the bearing 4 with a seat is penetrated by the bolt 5, so that the bottom of the bolt 5 extends to the inner wall of the base 1, and the bolt 5 is threadedly connected to the base 1, so that the bolt 5 is fixed by the base 1, thereby fixing the bearing 4 with a seat above the base 1. Then, the cylinder 3 and the bearing 4 with a seat can be removed by removing the bolt 5 inside the cylinder 3 and the bearing 4 with a seat.

[0023] In a preferred embodiment, gear 7 is located above rack 14 and meshes with the top of rack 14.

[0024] In the above structure, the cylinder 3 is activated, causing the connector 15 to move, which in turn causes the connector 15 to move the rack 14. The rack 14 meshes with the top gear 7, causing the gear 7 to rotate. The gear 7 then drives the internal keyed rotating shaft 6 to rotate, which in turn drives the gear 8 to rotate.

[0025] In a preferred embodiment, gear 8 is located above rack 11, and gear 8 meshes with the top of rack 11.

[0026] In the above structure, the rotation of the keyed rotating shaft 6 causes the keyed rotating shaft 6 to drive the gear 8 to rotate, which in turn causes the gear 8 to mesh with the bottom rack 11 and drive the rack 11 to move, which in turn causes the rack 11 to drive the external connecting rod 16, switch plate 17 and locking pin 18 to move.

[0027] In a preferred embodiment: the number of teeth of gear 7 is greater than the number of teeth of gear 8, and the height of rack 11 is greater than the height of rack 14.

[0028] In the above structure, the diameter of gear 7 is larger than that of gear 8, so that when gear 7 rotates, the rotation speed of its outer teeth is lower than that of gear 8. At the same time, the height of rack 11 is higher than that of rack 14, so that rack 11 can mesh better with gear 8.

[0029] In a preferred embodiment, the shape of the locking pin 18 is adapted to the inner wall of the connecting rod 16 and the switch plate 17, and the thickness of the switch plate 17 is adapted to the inner wall of the connecting rod 16.

[0030] In the above structure, by placing the switch plate 17 on the inner wall of the connecting rod 16, the inner wall of the switch plate 17 coincides with the through hole on the outer wall of the connecting rod 16. At this time, by inserting the locking pin 18 into the interior of the connecting rod 16 and the switch plate 17, the connecting rod 16 and the switch plate 17 are fixed by the locking pin 18.

[0031] In a preferred embodiment, the outer wall of the connector 15 on the side away from the cylinder 3 is threaded, and the thread on the outer wall of the connector 15 is adapted to the inner thread of the threaded sleeve 19.

[0032] In the above structure, by placing the threaded sleeve 19 outside the connector 15, the inner wall of the threaded sleeve 19 is aligned with the side of the connector 15 away from the cylinder 3. At this time, by rotating the connector 15, the connector 15 adapts to the thread on the inner wall of the threaded sleeve 19, thereby moving the threaded sleeve 19 in the direction of the cylinder 3. When the threaded sleeve 19 completely covers the connector 15, a fixed relationship is completely established between the connector 15 and the threaded sleeve 19.

[0033] Working principle: When using the equipment, starting cylinder 3 causes the connector 15 to move, which in turn moves the connecting rod 16 and rack 14. Rack 14 meshes with gear 7, causing gear 7 to rotate. Gear 7 then rotates the internal keyed rotating shaft 6, which in turn rotates gear 8. Gear 8 meshes with the bottom rack 11, causing it to move. This, in turn, moves the external connecting rod 16, switch plate 17, and locking pin 18, thus activating the switch. The gear ratio between gears 7 and 8 is configured to achieve labor-saving operation. By removing bolt 5, the fixed relationship between the bearing 4 and the base 1 is eliminated, allowing the bearing 4 to be removed. This enables the removal of the keyed rotating shaft 6 inside the bearing 4, allowing the replacement of the keyed rotating shaft 6, gear 2 7, and gear 1 8. By removing the locking pin 18, the fixed relationship between the switch plate 17 and the connecting rod 2 16 is eliminated, allowing the switch plate 17 to be replaced. Simultaneously, by rotating the connector 15, the connector 15 is separated from the threaded sleeve 19 through its threaded connection, allowing the threaded sleeve 19 and rack 2 14 to be removed. Through the modular design of the entire equipment, the overall maintenance speed is improved, facilitating the use of the equipment.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
