Description

Technical Field

[0001] This application belongs to the field of missile fuze processing technology, and in particular relates to a fixing fixture for fuze assembly. Background Technology

[0002] The missile fuze is one of the core components of a missile, with a precise structure and extremely high assembly accuracy requirements. During the assembly, testing, and debugging of the fuze, it needs to be stably and reliably fixed in a specific position so that operators can perform delicate operations such as tightening screws, connecting wires, and calibrating parameters.

[0003] The process of assembling the missile fuse into the shell is generally fixed by a machining device on the work platform, that is, by pressing and fixing the shell with clamping screws. However, the existing clamping components are not stable enough, and may cause compression damage to the side walls when tightening the shell components, which affects product quality and reduces production efficiency. Utility Model Content

[0004] To address the technical problems of existing clamping components being unstable and potentially causing compression damage to the sidewalls of the housing components during fastening, which affects product quality and reduces production efficiency, this utility model provides a fixing clamp for fuse assembly.

[0005] In a first aspect, this application provides a fixing clamp for assembling a fuse, comprising:

[0006] A fixed frame, wherein a fixed base is fixedly connected to the bottom end of the fixed frame;

[0007] The missile casing is mounted inside the side wall of the mounting bracket and on the top of the mounting base, and a missile fuse is mounted on the top of the missile casing.

[0008] The clamping assembly consists of three sets of clamping assemblies arranged circumferentially on the outer side of the fixed frame. Each set of clamping assemblies includes a hydraulic rod, a connecting plate, a pair of moving rods, and a rubber plate.

[0009] A hydraulic rod, which is fixed to the outside of the fixed frame;

[0010] A connecting plate is fixedly connected to the output end of the hydraulic rod;

[0011] A movable rod, the outer end of which is fixed to the inner side of the connecting plate, and the inner end of which extends to the inner side of the fixed frame;

[0012] A rubber sheet is fixed to the inner end of the movable rod, and the inner side of the rubber sheet abuts against the missile casing;

[0013] A buffer assembly for protecting the missile casing is provided between the outer side of the rubber plate and the inner end of the moving rod.

[0014] According to an embodiment of this application, a fixing fixture for assembling a fuse is provided. By setting a buffer spring, when the hydraulic rod drives the connecting plate away from or close to the outside of the fixing frame, the extension and contraction of the buffer spring enables the moving rod in each group to stably and slowly drive each rubber plate to move synchronously, thereby realizing synchronous and stable clamping and release of the missile casing.

[0015] According to one embodiment of this application, the fixing clamp for assembling a fuse further includes: a baffle fixedly connected to the outer side of the moving rod, a compression spring fixedly connected between the inner side of the baffle and the outer side of the fixing frame, and the compression spring being disposed on the outer side of the moving rod.

[0016] According to one embodiment of this application, the buffer assembly includes a groove formed on the inner end of the moving rod, a buffer spring is installed inside the groove, a connecting post is fixedly connected to the outer end of the buffer spring, and the other end of the connecting post is fixedly connected to the outer side of the rubber plate.

[0017] According to one embodiment of this application, the inner end of the movable rod is fixedly connected with three first fixing rings in a circumferential array on the outer side, and the inner side of the fixing rings is provided with an elastic telescopic column.

[0018] Three slidable movable blocks are provided on the outer side of the rubber plate, and a second fixed ring is fixedly connected to the outer side of the movable blocks. The other end of the elastic telescopic column is hinged to the second fixed ring.

[0019] According to one embodiment of this application, a groove is provided on the outer side of the rubber sheet, and the movable block is slidably installed in the groove.

[0020] According to one embodiment of this application, a limiting groove is formed at the top of the fixing seat.

[0021] Secondly, this application provides a fixing clamp for assembling a fuse;

[0022] Including at least one of the following beneficial technical effects:

[0023] 1. By setting up a compression spring, when the hydraulic rod drives the connecting plate away from or near the outside of the fixed frame, the extension and contraction of the compression spring enables the moving rod in each group to stably and slowly drive each rubber plate to move synchronously, thereby achieving synchronous and stable clamping and release of the missile casing.

[0024] 2. This application, through the setting of buffer spring, elastic telescopic column and moving block, hinges the elastic telescopic column to the inner end of the moving block and moving rod, and the buffer spring is set in the groove of the inner end of the moving rod, which can improve the firmness of the rubber plate clamping work, thereby improving its processing stability. Furthermore, it avoids the problem of squeezing damage to the missile shell during the clamping process, ensuring product quality and processing efficiency.

[0025] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0031] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0032] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0033] Example 1:

[0034] This embodiment specifically describes the structure of a fixing fixture for fuse assembly, such as... Figures 1-4 As shown, it includes a seven-part structure: a fixing frame 1, a missile casing 2, a clamping assembly 3, a hydraulic rod 301, a connecting plate 302, and a rubber plate 304;

[0035] The fixed frame 1 has a fixed base 101 fixedly connected to its bottom end;

[0036] Missile casing 2 is installed inside the side wall of the mounting bracket 1 and on the top of the mounting base 101, and a missile fuse 201 is installed on the top of the missile casing 2.

[0037] Clamping assembly 3, three sets of clamping assemblies 3 are arranged in a circular manner on the outside of the fixed frame 1. Each set of clamping assembly 3 includes a hydraulic rod 301, a connecting plate 302, a pair of moving rods 303 and a rubber plate 304.

[0038] Hydraulic rod 301 is fixed to the outside of the fixed frame 1;

[0039] Connecting plate 302 is fixedly connected to the output end of hydraulic rod 301;

[0040] The movable rod 303 has its outer end fixed to the inner side of the connecting plate 302, and its inner end extends to the inner side of the fixed frame 1.

[0041] Rubber plate 304 is fixed to the inner end of the moving rod 303, and the inner side of the rubber plate 304 abuts against the missile casing 2.

[0042] A buffer assembly 6 for protecting the missile casing 2 is provided between the outer side of the rubber plate 304 and the inner end of the moving rod 303.

[0043] The entire process of fixing the fixture is as follows: the missile casing 2 is placed inside the fixing frame 1, and the bottom end of the missile casing 2 is located at the top of the fixing seat 101, and the whole is in a vertical state;

[0044] At this time, the hydraulic rod 301 fixed to the outer side of the fixed frame 1 is opened and retracted. When the output end of the hydraulic rod 301 retracts, the connecting plate 302 will drive the moving rod 303 to move towards the inside of the fixed frame 1, so that multiple rubber plates 304 fit against the outside of the missile shell 2, achieving stable clamping and fixing.

[0045] like Figure 1 and Figure 4 As shown, in some examples, a fixing fixture for assembling a fuse further includes: a baffle 4 fixedly connected to the outer side of the moving rod 303, a compression spring 5 fixedly connected between the inner side of the baffle 4 and the outer side of the fixing frame 1, and the compression spring 5 is disposed on the outer side of the moving rod 303.

[0046] By adopting the above technical solution: with the setting of the compression spring 5, when the hydraulic rod 301 retracts, the connecting plate 302 will drive the moving rod 303 to move towards the fixed frame 1. At this time, the compression spring 5 located between the baffle 4 and the outside of the fixed frame 1 will retract synchronously, ensuring that the moving rod 303 in each group can stably and slowly drive each rubber plate 304 to fit against the missile housing 2, thereby achieving stable clamping of the outside of the missile housing 2. Finally, the missile fuse 201 is installed on the top of the missile housing 2.

[0047] Example 2:

[0048] like Figure 2 - Figure 4 As shown, this embodiment specifically describes the specific structure in Embodiment 1.

[0049] In some examples, the buffer assembly 6 includes a groove 601 formed on the inner end of the moving rod 303, a buffer spring 602 installed inside the groove 601, a connecting post 603 fixed to the outer end of the buffer spring 602, and the other end of the connecting post 603 fixed to the outer side of the rubber plate 304.

[0050] like Figure 3 and Figure 4 As shown, in some examples, the inner end of the moving rod 303 is fixedly connected to three first fixing rings 604 in a circumferential array on the outer side, and the fixing rings are hinged with elastic telescopic columns inside.

[0051] Three slidable movable blocks 605 are provided on the outer side of the rubber plate 304. A second fixed ring 606 is fixedly connected to the outer side of the movable block 605. The other end of the elastic telescopic column is hinged to the second fixed ring 606.

[0052] like Figure 3 and Figure 4 As shown, in some examples, a groove 7 is provided on the outer side of the rubber sheet 304, and the moving block 605 is slidably installed in the groove 7.

[0053] like Figure 2 As shown, in some examples, a limiting groove 8 is provided at the top of the fixing seat 101.

[0054] By adopting the above technical solution: when fixing the large-sized missile casing 2 within the diameter of the fixing frame 1, when the inner side of the rubber plate 304 abuts against the missile casing 2, the connecting post 603 fixed to the outer side of the rubber plate 304 will slide towards the inner end groove 601 of the moving rod 303 and squeeze the buffer spring 602 installed in the groove 601. This can prevent the side wall of the missile casing 2 from being squeezed and damaged when the missile casing 2 component is tightened or the fixing frame 1 is subjected to external impact.

[0055] Meanwhile, the elastic telescopic column hinged between the first fixed ring 604 and the second fixed ring 606 first rotates at its own angle, and then drives the moving block 605 to slide upward from the bottom of the slide groove 7. The sliding distance of the moving block 605 is proportional to the compression force of the buffer spring 602, which further improves the stability and limit of the clamping assembly 3 on the missile shell 2.

[0056] The setting of the limiting groove 8 and the cooperation of the clamping component 3 can ensure that the missile casing 2 is in a vertical position, which facilitates the installation of the missile fuse 201.

[0057] The working principle of a fixing fixture for fuse assembly in this application embodiment is as follows:

[0058] Before installation, the missile casing 2 is placed vertically and stably inside the fixed frame 1 by the mechanical claw, and the bottom end of the missile casing 2 is located in the limiting groove 8 opened at the top of the fixed base 101.

[0059] At this time, the hydraulic rod 301 fixed to the outer side of the fixed frame 1 is opened and retracted. When the output end of the hydraulic rod 301 retracts, the connecting plate 302 will drive the moving rod 303 to move towards the inside of the fixed frame 1, so that multiple rubber plates 304 fit against the outside of the missile shell 2, achieving stable clamping and fixing.
