Description

Technical Field

[0001] The utility model relates to the technical field of tube-loading equipment, in particular to a tool for punching holes at the end of a launch tube and a launch tube. Background Art

[0002] Large-scale storage and transportation catapult launch tubes mainly provide the necessary protection environment for the storage, transportation and launch of projectiles. In order to ensure the efficient operation and installation reliability of the catapult launch tubes, the two end faces of the launch tubes need to be finely processed and holes are drilled to install wire screw sleeves for positioning. This step is crucial to ensuring the accuracy and stability of the launch tubes.

[0003] However, in the current processing process, the processing of the end hole of the launch tube still faces certain challenges. In most cases, in order to ensure the processing accuracy and relative position relationship, it is necessary to rely on large-scale equipment such as CNC machine tools, gantries or turning and milling compounds. Since these equipment consumes a lot of time and energy in the debugging, calibration of benchmarks and processing, in addition, the use of these large equipment is also dependent on site, energy and manpower. Therefore, it is necessary to design a new type of launch tube end drilling tooling and launch tube to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a launching tube end punching tool and a launching tube, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] In the first aspect, a launch tube end punching tool is proposed, comprising: a limit plate, a limit block and a punching template;

[0007] The punching template is used to limit the punching equipment;

[0008] The limiting plate is fixed on one side of the punching template and is used to reinforce the punching template;

[0009] There are two limit blocks, which are respectively installed at two ends of a limit plate where the limit plate is installed on one side. The limit plate is surrounded by the two limit blocks. The limit blocks are used to be assembled in the launch tube.

[0010] Furthermore, the limiting plate, limiting block and punching template are connected and assembled by screws.

[0011] Furthermore, the limiting plate and the inner cavity of the launching tube are connected for radial positioning, and the limiting plate and the punching template share the same center.

[0012] Furthermore, the outer surface of the punching template is provided with tooling lines, and the inner edge of the punching template is provided with a plurality of bushing holes, which are evenly distributed in the punching template at equal angles with the center of the punching template as a reference point.

[0013] Secondly, to improve the above technical solution, this application proposes a launch tube, which is suitable for any of the above-mentioned launch tube end drilling tools, including:

[0014] The barrel body, the middle end of the barrel body is concave into the barrel, and wire grooves are respectively opened on both sides of one end of the outer side of the barrel body. The other end of the outer side of the barrel body is used to install the punching tool at the end of the launch tube. The outer side of the barrel body is provided with a barrel scale line with one end extending from the wire groove to the outside of the punching tool at the end of the launch tube, and the barrel scale line and the tool scale line are aligned.

[0015] Furthermore, guide grooves adapted to the limit blocks are respectively provided on both sides of the inner wall of the barrel close to the end of the punching tool at the end of the launch barrel.

[0016] Compared with the existing technology, the launch tube end punching tool and the launch tube are designed with a combined punching tool. The radial positioning is performed by the inner cavity of the launch tube and the circumferential positioning is performed by the guide groove to ensure the punching accuracy. This solves the problem that the launch tube end processing must be carried out on a machine tool. This not only expands the scope of application of the device, but also improves the flexibility and convenience of the device in actual use.

[0017] In addition, the positioning hole of the tool is equipped with an aluminum alloy bushing with a replaceable structure. By changing the hole diameter, it can be used as a positioning tool for end gluing assembly, further improving the scope of use of the device. BRIEF DESCRIPTION OF THE DRAWINGS
