Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary disassembly tools, and more specifically relates to a disassembly and assembly positioning device for suspension components in an inertial navigation case. Background Art

[0002] Usually, the part that is suspended and installed in the inertial navigation chassis is the inertial sensitive component (hereinafter referred to as the platform), which is suspended and connected to the inner wall of the chassis through the shock absorbers on both sides of itself. Due to the space size limitation of the internal installation cavity of the inertial navigation chassis, after the platform is installed in the chassis, the space around the platform and the inner wall of the chassis is very narrow, and the upper surface of the platform is also nearly flush with the upper surface of the chassis. When the platform is removed from the chassis, it is impossible to hold the platform up and take it out by hand or general tools; when it is installed in the chassis, it is also impossible to put the platform into the chassis by hand or general tools, and accurately suspend it and align it to the installation position. This makes it very inconvenient to repair the product, and when disassembling the platform, as long as the screws connecting the platform and the chassis are unscrewed, the platform can easily slip out of the chassis, causing product damage. Utility Model Content

[0003] The utility model aims to provide a disassembly and assembly positioning device for a suspension component in an inertial navigation chassis, so as to solve the technical problems of low efficiency and low safety of the platform disassembly and assembly in the prior art.

[0006] A connecting portion, disposed on the mounting member and used for connecting the platform body;

[0007] A lap joint, provided on the mounting member and used for lap jointing on the top of the chassis; and

[0008] The positioning part is arranged on the mounting member and is used for aligning and positioning with the screw holes provided on the chassis. When the positioning part is aligned with the corresponding screw holes of the chassis, the platform is located at the designated mounting position.

[0009] In combination with the above technical solution, in a possible implementation manner, the connecting portion is a plurality of through holes provided on the mounting member, and screw holes are provided on the platform at positions corresponding to the connecting portions.

[0010] In combination with the above technical solution, in a possible implementation manner, the overlapping portion is an overlapping outer edge connected to the edge of the mounting member, and there are at least two overlapping outer edges located on two opposite sides of the mounting member.

[0011] In combination with the above technical solution, in a possible implementation manner, the positioning portion is a positioning hole opened on the mounting member.

[0012] In combination with the above technical solution, in a possible implementation manner, a handle is provided on a side of the mounting member facing away from the mounting surface of the platform.

[0013] In combination with the above technical solution, in a possible implementation manner, the handle and the mounting member are detachably connected.

[0014] In combination with the above technical solution, in a possible implementation, the mounting member is connected to the handle by bolts, a plurality of connection holes are provided on the mounting surface of the mounting member, and a threaded hole is provided on the end surface of the handle.

[0015] In combination with the above technical solution, in a possible implementation, the connecting hole is a T-shaped hole, and the head of the bolt is located in the connecting hole.

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only part of the embodiments of the present application, not all of the embodiments, and the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] A disassembly and assembly positioning device for a suspension component in an inertial navigation chassis provided by the utility model is now described.

[0025] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a disassembly and assembly positioning device for a hanging component in an inertial navigation chassis, comprising a mounting member 1, a connecting portion 2, an overlapping portion 3 and a positioning portion 4; the connecting portion 2 is arranged on the mounting member 1 and is used to connect the platform; the overlapping portion 3 is arranged on the mounting member 1 and is used to overlap the top of the chassis; the positioning portion 4 is arranged on the mounting member 1 and is used to align and position with the screw holes provided in the chassis. When the positioning portion 4 is aligned with the corresponding screw holes of the chassis, the platform is located at a specified installation position.

[0026] Specifically, the mounting member 1 is a plate-shaped structure.

[0027] The present embodiment provides a disassembly and assembly positioning device for suspension components in an inertial navigation chassis. Compared with the prior art, when installing a platform, the platform is first installed on the mounting member 1 through the connecting portion 2, the mounting member 1 together with the platform is placed on the chassis and overlapped through the overlapping portion 3, and then the positions of the mounting member 1 and the platform are adjusted through the positioning portion 4. After the platform is connected to the chassis, the connection between the mounting member 1 and the platform is released. When disassembling the platform, the mounting member 1 is first overlapped on the chassis and connected to the platform, and then the connection between the platform and the chassis is released. The mounting member 1 and the platform can be taken out together and then removed, thereby improving the disassembly and assembly efficiency and safety of the platform.

[0028] like Figure 1 to Figure 2 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0029] The connection part 2 is a plurality of through holes formed on the mounting member 1 , and screw holes are formed on the platform at positions corresponding to the connection part 2 .

[0030] Specifically, in this embodiment, the connecting portion 2 includes four through holes and is distributed at four corners close to the mounting member 1 , and screw holes are provided at the corresponding four corners on the platform.

[0031] When connecting the platform body and the mounting member 1, one end of the bolt is first passed through the through hole of the connecting portion 2 on the mounting member 1 and then screwed into the screw hole on the platform body, so that the head of the bolt is tightly pressed against the surface of the mounting member 1, which can avoid damage to the platform body caused by the bolt head, and the disassembly and assembly operation between the platform body and the mounting member 1 is convenient.

[0032] like Figure 1 to Figure 2 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0033] The overlapping portion 3 is an overlapping outer edge connected to the edge of the mounting member 1 . There are at least two overlapping outer edges located on two opposite sides of the mounting member 1 .

[0034] Specifically, in this embodiment, the overlapping portion 3 and the mounting member 1 are formed as one piece, and the sum of the widths of the mounting member 1 and the overlapping portion 3 is greater than the width of the chassis opening.

[0035] The mounting member 1 can be directly placed on the chassis to achieve stable overlap between the overlapping portion 3 and the chassis, thereby improving the convenience of disassembly and assembly of the platform.

[0036] like Figure 1 to Figure 2 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0037] The positioning portion 4 is a positioning hole formed on the mounting member 1 .

[0038] Specifically, in order to match the inertial navigation chassis model, in this embodiment, positioning holes are opened on the overlapping portion 3, and there are four positioning holes in total and they are distributed in a rectangular shape.

[0039] Since the overlapping portion 3 is directly overlapped on the top of the chassis, it is easier to observe by aligning the four positioning holes on the overlapping portion 3 with the corresponding screw holes on the top surface of the chassis, which can make the installation position adjustment of the platform more accurate and convenient.

[0040] like Figures 1 to 3 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0041] Two handles 5 are provided on the side of the mounting member 1 facing away from the mounting surface of the platform.

[0042] Furthermore, the handle 5 and the mounting member 1 are detachably connected.

[0043] Furthermore, the mounting member 1 is connected to the handle 5 by bolts, a plurality of connection holes 11 are provided on the mounting surface of the mounting member 1 , and a threaded hole 51 is provided on the end surface of the handle 5 .

[0044] Furthermore, the connecting hole 11 is a T-shaped hole, and the head of the bolt is located in the connecting hole 11 .

[0045] The setting of the handle 5 can make it more convenient to lift and place the mounting member 1. After the platform is installed on the mounting member 1, the platform can be oriented by holding the two handles 5, so that the platform can be more stably and accurately inserted into the chassis, further improving the convenience of disassembly and assembly of the platform.

[0046] The handle 5 can be removed from the mounting member 1 by bolts, which is convenient for separate packaging and transportation of the mounting member 1 and the handle 5 of the plate-like structure; the T-shaped connecting hole 11 can prevent the head of the bolt from protruding from the platform mounting plate on the mounting member 1, thereby avoiding affecting the disassembly and assembly of the platform.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0048] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.
