Description

Technical Field

[0001] The present application belongs to the technical field of auxiliary tooling, and specifically relates to a bonding and positioning device for external components of a launch tube. Background Art

[0002] In order to realize the launching function of the weapon launch tube made of composite materials, some parts with special functions need to be fixed on the surface of the launch tube. These parts are distributed in different positions on the launch tube body, and have size requirements and position requirements with each other. In order to ensure the position and axial size requirements of the parts on the launch tube, it is necessary to adopt a suitable method for positioning. Because the launch tube body is made of composite materials, the traditional welding fixing method is no longer applicable to the composite launch tube. At present, the functional parts are fixed and bonded by gluing technology. In small batch production, according to the structural characteristics of the product, the surface of the launch tube is first marked with lines, and then the parts are axially positioned with a vernier caliper and a single positioning aid. The production efficiency is low and the dimensional consistency is difficult to ensure.

[0003] In order to meet the tasks of mass production and the accuracy of part position and axial dimensions, it is necessary to design a comprehensive bonding device that can quickly and accurately position the parts on the launch tube.

[0004] Because launch tubes have different lengths and calibers, if a bonding device is made for each launch tube, multiple bonding devices will need to be made when producing multiple products, resulting in a waste of resources and taking up site space. In order to meet the bonding needs of launch tubes of different calibers and lengths (within a certain range), a comprehensive bonding device needs to be designed. Utility Model Content

DETAILED DESCRIPTION

[0033] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present application, and should not be understood as limiting the present invention.

[0034] The external components of the launch tube include a mounting seat, a pressure regulating valve, a barrel ring, a slider, and a handle seat; the present application is suitable for accurately positioning these components and the launch tube when these components are bonded to the surface of the launch tube.

[0035] Example 1

[0036] A bonding device for external components of a launch tube comprises a frame, a support assembly mounted on the frame, a launch tube length positioning structure and a launch tube radial positioning structure mounted on the frame; the support assembly is provided with a plurality of positioning blocks for positioning external components on the launch tube 31.

[0037] The frame includes a base plate 1, a left end plate 26 and a right end plate 10 whose lower ends are vertically mounted on the base plate 1, and an upper support plate 11 mounted horizontally on the upper ends of the left end plate 26 and the right end plate 10; the left end plate 26 and the right end plate 10 are arranged relatively parallel; the left end plate 26 and the right end plate 10 are fixed to the base plate 1 by bolts 2.

[0038] A lower support plate 3 for reinforcing the frame strength is installed at the lower part of the left end plate 26 and the right end plate 10 .

[0039] like Figure 1 , 2 As shown, the support assembly includes a front support plate 4 and a rear support plate 30 which are respectively fixedly connected to the frame; the front support plate 4 and the rear support plate 30 are arranged relatively parallel on both sides of the frame.

[0040] The detailed structure is that the front support plate 4 and the rear support plate 30 are fixedly connected to the left end plate 26 and the right end plate 10 of the frame by pins 5 and screws 6;

[0041] The front support plate 4 and the rear support plate 30 are both provided with a plurality of square holes for positioning the positioning blocks. The positions of the square holes are determined according to the positions of the external components on the launch tube 31.

[0042] The positioning blocks include a barrel ring positioning block 12, a slider positioning block 16, a mounting seat positioning block 20, a pressure regulating valve positioning block 22, and a handle seat positioning block 14 installed on the rear support plate 30; the above positioning blocks are positioned with the square holes of each support plate through functional pins 13 and positioning screws 15 respectively.

[0043] The launch tube length positioning structure includes a breech block positioning structure and a muzzle positioning structure;

[0044] The breech block positioning structure includes a breech block positioning piece 25 fixedly connected to the left end plate 26, a support rod 17 slidably connected to the breech block positioning piece 25, and an extension block 24 abutting against the breech block positioning piece 25; the left end of the launch tube 31 abuts against the extension block 24; and the radial positioning structure is installed on the support rod 17.

[0045] The muzzle positioning structure includes a muzzle positioning component 9 and a positioning plate 8 slidably connected to the right end plate 10, and a fixing screw 7 and a functional screw 29 on the right end plate 10; the positioning plate 8 is assembled on the right end plate 10 with the functional screw 29 and the fixing screw; when the launch tube 31 is positioned, the right end of the launch tube 31 abuts against the muzzle positioning component 9.

[0046] When in working state, the set screw 7 is rotated to apply pressure to the right end of the launch tube 31 through the positioning plate 8 and the muzzle positioning component 9, so that the left end of the launch tube 31 is pressed against the extension block 24, thereby axially positioning the launch tube 31.

[0047] like Figure 6-8 As shown, the radial positioning structure includes a step provided on the support rod 17, a retaining ring 21 abutting against the step, a first gasket abutting against the extension block 24, an expansion ring 23 abutting against the first gasket at one end, a second gasket 32 ​​abutting against the other end of the expansion ring 23, and a nut 28 threadedly connected to the support rod 17; the end surface of the retaining ring 21 abuts against the second gasket 32; the first gasket is sleeved on the breech block positioning member 25, and the second gasket 32 ​​is slidably connected to the support rod 17;

[0048] The first gasket and the second gasket 32 ​​have the same structure, both of which are frustum-shaped; the expansion ring 23 is sleeved on the first gasket and the second gasket 32 ​​which are arranged opposite to each other;

[0049] like Figure 6As shown, both ends of the expansion ring 23 are provided with inner conical surfaces 232, and the inner conical surfaces 232 are matched with the outer conical surfaces of the second gasket 32 ​​and the first gasket respectively;

[0050] The expansion ring 23 has an inner conical surface 232 and an opening groove 231 on its outer wall, so that the expansion ring 23 can expand under the pressure of the second gasket 32 ​​and the first gasket;

[0051] The nut 28 abuts against the breech block positioning piece 25;

[0052] The left end of the support rod 17 passes through the expansion ring 23, the extension block 24, the breech block positioning piece 25, and the left end plate 26, and is fixed together with a thick washer 27 and a nut 28.

[0053] Working process of this application:

[0054] This application is mainly used in the process of positioning and bonding parts of a weapon launch tube 31. First, the muzzle positioning component 9 is removed from the device, and then the launch tube 31 passes through the circular hole of the right end plate and slides along the support rod 17. Finally, one end of the launch tube 31 hits the positioning surface of the extension block 24, and then the smaller end of the muzzle positioning component 9 is installed into the launch tube 31, and the large end of the muzzle positioning component 9 is inserted into the hole of the right end plate 10 to fix the other end of the launch tube 31. At this time, by screwing the nut 28, the support rod 17 moves to the left under the drive of the thread force, and the step 21 of the support rod 17 pushes the second gasket 32 ​​to expand one end of the expansion ring 23, and the other end of the expansion ring 23 is expanded by the first gasket. The expanded expansion ring 23 radially positions the launch tube 31. After accurate positioning, the entire launch tube 31 is axially positioned by the muzzle positioning component 9. After the axial and radial positioning is completed, the parts are positioned by other positioning blocks.

[0055] The circumferential spacing angle of the support plate of this embodiment is 90°, and the spacing of the reserved holes of the support plate is also specifically fixed. Obviously, the embodiments of this application are only for the purpose of clearly illustrating the examples made in this application, and are not limitations on the implementation methods of this application. For the relevant field, the spacing of the support plates is not limited to 90°, and the reserved holes of the support plates are not limited to specific values. They can be modified within the spirit and principles of this application. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the scope of protection of the claims of this application.

[0056] Example 2

[0057] This embodiment is basically the same as Embodiment 1, except that:

[0058] It also includes a sliding structure for guiding the launch tube 31 on the support rod 17.

[0059] The sliding structure includes a spacer sleeve 18 and a support pad 19 which are arranged on the support rod 17 from left to right in close contact with the expansion ring 23; the support pad 19 is used to guide the launch tube 31 when it passes through the support rod 17. The number of support pads 19 is determined according to the length of the launch tube 31. Generally, the support pads 19 are preferably spaced 300-500mm apart. If the spacing is too long, it is easy to cause the launch tube 31 to not be accurately sleeved on the expansion ring 23 when passing through the support rod 17, causing the launch tube 31 to be eccentric.

[0060] The outer diameter of the support pad 19 is preferably 0.1 mm smaller than the inner diameter of the launch tube 31 to prevent the launch tube 31 from getting stuck when passing through.

[0061] The support pad 19 is provided to enable the launch tube 31 to slide quickly toward the positioning surface of the extension block.

[0062] Example 3

[0063] This embodiment is basically the same as Embodiment 1, except that a functional screw 29 and a set screw 7 are provided on the right end plate 10 to fix the positioning plate 8 on the right end plate 10. When in working state, the positioning plate 8 is fixed by the set screw 7 and the functional screw 29, thereby preventing the muzzle positioning component 9 from falling off from the right end plate 10 during use.

[0064] The above-mentioned embodiments describe content in a relatively detailed and specific manner, expressing the preferred embodiments of the present application, and are only used to illustrate the technical ideas and features of the present application. The purpose is to enable technicians in this field to understand the content of the present utility model and implement it accordingly, but it is not limited to the present application. The patent scope of the present application cannot be limited only by this embodiment. That is, any equivalent changes or modifications made to the spirit disclosed in the present application, for researchers or technicians in this field, without departing from the structure of the present application, local improvements within the system and changes and conversions between subsystems, etc., are still within the patent scope of the present application.
