Abstract
The invention relates to a multistage gas gun anti-recoil device and belongs to the technical field of mechanical machining. The multistage gas gun anti-recoil device comprises a cylinder block I (1),a cylinder block II (3), a buffer rod (5), a gas injection valve (6) and a balance valve (7). The cylinder block I is fixedly connected with a gun piece. The cylinder block II is fixedly connected tothe cylinder block I. One end of the buffer rod is movably connected with the cylinder block II. One end of the buffer rod is connected with the gun piece. Cavities of the cylinder block I and the cylinder block II are filled up with gas at different pressures through the gas injection valve. The cavities communicate through the balance valve. At different stages of the gas gun shooting process,the pressures of the cavities are adjusted through the balance valve to implement buffering on recoil force and forward impact force. Compared with the prior art, the multistage gas gun anti-recoil device can accurately return zero to shifting generated under different working conditions within short time in the gas gun shooting process, gently absorb peak stress generated in different stress directions and reduce the requirements for rigidity and strength and the foundation load bearing strength, is simple in structure and achieves the combined operation effect of multiple recoil mechanisms and counter-recoil mechanisms of an original gas gun.
Description
technical field [0001] The invention relates to a multi-stage gas cannon anti-recoil device, which belongs to the technical field of gas cannon anti-recoil devices. Background technique [0002] The recoil force and forward momentum generated by the gas guns of two or more levels (abbreviated as multi-stage gas guns) during the firing process are too large to cause damage to the gun body itself and the foundation. The existing anti-recoil structure uses a combination of multiple parking machines and re-entry machines to reduce the impact force of the recoil. The structure is complex, and the anti-recoil resistance is adjusted through fluid holes of different sizes. The buffer function fails, destroying the gun body and foundation. The forward momentum that occurs at different stages of the firing process can only be absorbed by the gun body, which affects the rigidity of the gun body. Contents of the invention [0003] The purpose of the present invention is to overcome t...
