Description

Technical Field

[0001] This utility model relates to a device for closing and unloading the barrel of a rocket, belonging to the field of barrel detection technology. Background Technology

[0002] After the rocket projectiles are assembled, they need to undergo a bore inspection. This involves pushing the finished rocket projectiles through a bore fitting machine into a bore gauge to check the coaxiality of its various parts. The initial bore fitting operation involves placing the bore gauge on a platform, manually hoisting the projectile to the gauge opening, and then manually using a crane to slowly push the projectile into the gauge. After the projectile is inside the bore, a tool is used to push it out of the gauge, and during this process, the crane lifts the projectile out again. This method is extremely inconvenient, and the swaying of the projectile on the slings can easily damage the workpiece due to misalignment between the projectile and the bore, posing a significant safety hazard. The inspection efficiency is also low.

[0003] In response to the above situation, we designed a dedicated bore-passing device that can conveniently, safely and stably push the product into the bore gauge, and safely remove the product after bore-passing. Utility Model Content

[0004] The purpose of this invention is to solve the problems of inconvenient operation, high risk and low detection efficiency in traditional processes for barrel inspection, and to provide a barrel closing and unloading device for rocket products.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] The present invention relates to a rocket projectile chamber closing and unclosing device, comprising a support base with a flat upper surface, an unclosing assembly disposed on the left side of the upper surface of the support base, a chamber closing gauge horizontally supported by a bracket in the middle of the upper surface of the support base, and a chamber closing assembly disposed on the right side of the upper surface of the support base.

[0007] The unloading assembly includes a positioning nut horizontally supported on the upper surface of the support base by a bracket, a drive screw threaded into the inner cavity of the positioning nut, and a handle fixed to the left end of the drive screw.

[0008] The chamber assembly includes two sets of inner and outer guide rails arranged inside and outside the upper surface of the support base, a front support trolley slidably connected to the inner guide rail, a rear support trolley slidably connected to the outer guide rail, a connecting rod hinged between the front and rear support trolleys, and a push plate fixed to the rear end of the rear support trolley; both the inner and outer guide rails are composed of two sections of rail with a lower front section and a higher rear section.

[0009] Before the chamber is closed, the front support carriage and the rear support carriage are respectively supported on the rear section of the inner guide rail and the rear section of the outer guide rail. The rocket under test is supported above the front support carriage and the rear support carriage, and the axis of the rocket under test is aligned with the inner cavity axis of the chamber gauge. When the rocket under test moves to the left with the front support carriage and the rear support carriage until the outer wall of the front end of the rocket body contacts the inner wall of the chamber gauge, the front support carriage moves to the front section of the inner guide rail and separates from the rocket under test. When the rocket under test moves to the left with the rear support carriage until the center of mass of the rocket body enters the inner cavity of the chamber gauge, the rear support carriage moves to the front section of the outer guide rail and separates from the rocket under test. The drive screw is driven to rotate by the handle, so that the right end of the drive screw pushes the rocket under test to the right to retract from the chamber.

[0010] Beneficial effects

[0011] This utility model's barrel closing and ejection device allows rockets to be easily, accurately, and safely loaded and ejected from the barrel. It performs well, improving testing efficiency while reducing labor intensity and enhancing inherent operational safety. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example

[0017] like Figure 1 As shown, a rocket projectile barrel closing and unclosing device of this utility model includes a support base 1 with a flat upper surface, an unclosing assembly disposed on the left side of the upper surface of the support base 1, a barrel closing gauge 6 horizontally supported by a bracket in the middle of the upper surface of the support base 1, and a barrel closing assembly disposed on the right side of the upper surface of the support base.

[0018] The unloading assembly includes a positioning nut 7 horizontally supported on the upper surface of the support base by a bracket, a drive screw 8 threadedly connected to the inner cavity of the positioning nut 7, and a handle 9 fixed to the left end of the drive screw 8.

[0019] The chamber assembly includes two sets of inner guide rails 12 and outer guide rails 11 arranged internally and externally on the upper surface of the support base, such as... Figure 2 As shown; a front support trolley 5 is slidably connected to the inner guide rail 12, a rear support trolley 3 is slidably connected to the outer guide rail 11, a connecting rod 4 is hinged between the front support trolley 5 and the rear support trolley 3, and a push plate 2 is fixed to the rear end of the rear support trolley 3; both the inner guide rail 12 and the outer guide rail 11 are composed of two sections of rail with a lower front section and a higher rear section;

[0020] During chamber closing, the front support trolley 5 and the rear support trolley 3 are respectively supported on the rear section of the inner guide rail 12 and the rear section of the outer guide rail 11. The rocket under test 10 is supported above the front support trolley 5 and the rear support trolley 3, and the axis of the rocket under test 10 is aligned with the inner cavity axis of the chamber closing gauge 6. The push plate pushes the rocket under test 10 to move to the left along with the front support trolley 5 and the rear support trolley 3. When the rocket under test 10 moves to the front end of the projectile body... When the wall contacts the inner wall of the bore gauge 6, the front support trolley 5 moves to the front section of the inner guide rail 12 and separates from the rocket under test 10. The rocket under test 10 continues to move to the left with the rear support trolley 3. When the rocket under test 10 moves to the center of mass position of the projectile and enters the inner cavity of the bore gauge 6, the rear support trolley 3 moves to the front section of the outer guide rail 11 and separates from the rocket under test 10. It continues to push the rocket under test 10 to the left until the bore is fully closed.

[0021] During ejection, the drive screw 8 is rotated by the handle 9, causing the right end of the drive screw 8 to push the rocket under test 10 to the right for ejection. The rear end of the rocket under test 10 first contacts the push plate 2. The push plate 2 drives the rear support trolley 3 to move from the front section to the rear section of the outer guide rail 11, so that the rear support trolley is supported at the bottom of the rear end of the rocket under test 10. The rear support trolley 3 pulls the front support trolley 5 from the front section to the rear section of the inner guide rail 12 through the connecting rod 4, so that the front support trolley 5 is supported at the bottom of the front side of the rocket under test 10.
