Description

Technical Field

[0001] The invention belongs to the technical field of rocket parts assembly, and in particular relates to a drilling positioning structure for a rocket limit block and cushion block. Background Art

[0002] Due to the influence of parts processing errors, in order not to affect the positioning accuracy of the rocket in the launch tube, the rocket limit blocks and spacer screw mounting holes on the domestic rocket launchers are all drilled during the assembly of the rocket launchers. However, the clamping and fixing of the spacers during drilling only relies on bow clamps, and there is no other effective clamping and fixing method.

[0003] For example, the authorization announcement number "CN220240128U" is named an aviation rocket limit block pad drilling positioning structure. Although the screw mounting hole on the launch tube is drilled according to the bottom hole of the screw hole on the pad, the limit block and the pad are installed on the launch tube of the rocket launcher with screws. The structure is reasonable and simple, the positioning is reliable, the use process is simple and easy, and the drilled screw mounting hole has high position accuracy, but there is still a problem that the existing rocket limit block pad drilling positioning structure needs to use screws to fix the pad and the internal limit block on the rocket launcher. The inside of the launch tube, however, the stop block installed by the screw needs to be used in conjunction with the fixed plate set up at the end of the rocket launch tube. The limit block and the pad block can only be fixed to the inside of the launch tube by twisting the screw alone. However, during the actual installation process, the reserved position for drilling a hole in the limit block is located below the inner side of the fixed plate. Therefore, the reserved space is relatively small and difficult to operate with electric tools. However, it is obviously not realistic to rely on manual manpower to drill holes in the rocket limit block. Therefore, the existing aviation rocket limit block and pad block drilling and positioning structure is easily restricted by external space during drilling and installation.

[0004] At the same time, the existing rocket limit block and pad drilling positioning structure, because the rocket launch tube needs to be placed inside the launcher, but the inner wall of the launcher and the launch tube are not firmly fitted, so when the electric tool is drilling a hole in the rocket launch tube, it will generate relatively large vibration and force, so that the launch tube and the launcher are easy to loosen, and most rocket launchers are disposable, so the launch tube needs to be disassembled and reinstalled after the launcher is used after drilling, and the conventional way of installing the launch tube is to fix it with bolts, which takes a long time to disassemble and is not convenient to replace, which ultimately affects the low efficiency of the rocket limit block and pad drilling positioning structure. Summary of the invention

[0005] The purpose of the patent of this invention is to solve the problem that the drilling positioning structure of the rocket limit block and pad block is easily limited and has low efficiency, and to propose a rocket limit block and pad block drilling positioning structure.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0009] Preferably, the mounting frame is fixedly mounted above the base, the top end of the mounting frame is fixedly connected to the rocket launcher, and the upper end of the base is arranged relatively parallel to the launch tube.

[0010] Preferably, a launch tube is provided on the inner side of the mounting frame to facilitate disassembly of the fixing structure;

[0011] The launch tube easy-to-disassemble fixing structure comprises a first bolt, a second bolt and a rotation chamber;

[0012] The two first bolts are threadedly connected to both sides of the top of the mounting frame, the ends of the two first bolts are threadedly connected to the base, the mounting frame is internally rotatably installed with two rotating shafts, the outer sides of the two rotating shafts are threadedly connected with second bolts, the ends of the two second bolts are threadedly connected to the inner sides of the mounting frame, the outer walls of the two rotating shafts are fixedly connected with tightening blocks, the two rotating chambers are fixedly opened on the inner side of the mounting frame, and the two tightening blocks are movably connected to the rotating chambers.

[0014] Preferably, the ends of the two abutting blocks are movably connected to the inner side of the rocket launcher, and the top ends of the two abutting blocks are movably connected to the outer wall of the launch tube.

[0015] The patent of the present invention proposes a rocket limit block and pad drilling positioning structure, which has the beneficial effect that: the distance between the clamping plate and the limit block can be separated by twisting the connecting block with the threaded rod. At this time, the inner side of the connecting block is close to the outer wall of the launch tube, and the threaded rod can drive the clamping plate to be squeezed and moved in the direction of the limit block.

The structure that facilitates the disassembly of the launch tube is utilized to improve the utilization efficiency of the drilling and positioning structure of the rocket limit block pad.

[0030] Working principle:

[0031] First, when it is necessary to fix the limit block 61 and the cushion block 62 for drilling and positioning, the connecting block 65 will separate the distance between the clamping plate 64 and the limit block 61 by twisting the threaded rod 63. At this time, the inner side of the connecting block 65 is close to the outer wall of the launch tube 5 until the limit block 61 enters the interior of the launch tube 5. At this time, the threaded rod 63 is tightened again, and the threaded rod 63 will drive the clamping plate 64 to squeeze and move in the direction of the limit block 61, so that the cushion block 62 on the inner side of the clamping plate 64 will be close to the drilling hole on the outer wall of the launch tube 5. The reserved drilling groove 66 will facilitate the drilling and positioning of the drilling equipment. The anti-penetration block 67 is made of a wear-resistant and smooth stainless steel metal sheet that fits the size of the drilling hole. The anti-penetration block 67 can prevent the electric equipment from penetrating the limit block 61 during drilling and positioning. The limit block 61 and the cushion block 62 can be installed inside the rocket launcher as needed.

[0032] Then, when installing the launch tube 5 inside the rocket launcher 4, the second bolt 73 can be loosened first, and then the rotating shaft 72 can be freely rotated. When the rotating shaft 72 is rotated to a certain extent, the abutting block 74 will be driven to turn inside the rotating cavity 75 through the rotating shaft 72 until the top of the abutting block 74 fixes the launch tube 5 against the inner side of the rocket launcher 4, and then the second bolt 73 is tightened again to fix the rotating shaft 72 and the mounting frame 3;

[0033] Finally, a through hole 82 is opened on the inner side of the fixing plate 81 opposite to the end of the launching tube 5, and a structure that can be at a right angle to the end of the launching tube 5 is formed between the pushing block 84 at the top of the fixing plate 81 and the top plate 83, and the width distance between the rear side of the launching tube 5 and the fixing plate 81 can be limited by the top plate 83 and the pushing block 84.
