Detailed Implementation
[0057] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0058] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0059] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0060] like Figures 1 to 10 As shown, the present invention provides a skid-mounted landing gear assembly fixture with a buffer, comprising:
[0061] Support bracket 1 supports the overall assembly tooling of the buffer-type skid landing gear on the support surface; the support surface can be the ground or a placement surface at a certain limited area.
[0062] The slide tube clamping mechanism 2 is used to clamp the slide tube 31 of the buffer-type skid landing gear 3;
[0063] The fuselage positioning mechanism 4 is disposed on the side of the support 1 away from the support surface; the fuselage positioning mechanism 4 includes a fuselage fixing part 41 for fixing the fuselage connection 32 of the skid landing gear 3 with buffer, and a buffer fixing part 42 for fixing the buffer 33 of the skid landing gear 3 with buffer.
[0064] The fuselage positioning mechanism 4 is provided in two opposite directions; the fuselage fixing parts 41 of the two fuselage positioning mechanisms 4 are arranged facing each other; each fuselage positioning mechanism 4 is provided with two buffer fixing parts 42 that are symmetrically arranged relative to the position of its own fuselage fixing part 41.
[0065] In this utility model, by setting a support base to support the support surface, a stable foundation is provided for the entire assembly fixture, ensuring that the fixture will not shift or shake during the assembly process, thereby ensuring the smooth progress of the assembly work.
[0066] The slide tube clamping mechanism can firmly clamp the slide tube of the landing gear with a shock absorber, preventing the slide tube from moving or wobbling during assembly. This is crucial for improving assembly accuracy. Only when the position of the slide tube is precisely fixed can the subsequent connections between various components be ensured to be accurate, reducing assembly errors caused by slide tube position deviations, thereby improving the overall assembly quality of the landing gear.
[0067] The fuselage positioning mechanism is located on the side of the support base away from the support surface. It includes a fuselage fixing part for securing the fuselage connection of the skid-mounted landing gear with a buffer, and a buffer fixing part for securing the buffer. Furthermore, there are two opposing fuselage positioning mechanisms, with their fuselage fixing parts facing each other, and each mechanism has two buffer fixing parts symmetrically positioned relative to their respective fuselage fixing parts. This structural design allows for precise positioning and fixing of both the landing gear fuselage connection and the buffer simultaneously. On one hand, the two opposing fuselage fixing parts stably secure the fuselage connection from both sides, ensuring the accuracy of the fuselage's position during assembly and making the connection between the fuselage and other components smoother and more precise. On the other hand, the symmetrically positioned buffer fixing parts accurately position the buffer, allowing it to be accurately installed in the designated location and precisely fitted with the fuselage and skid-mounted landing gear. Since the buffer plays a crucial role in shock absorption and cushioning in a skid-mounted landing gear with a buffer, its installation accuracy directly affects the performance of the landing gear. This precise positioning and fixing method can greatly improve the installation accuracy of the buffer, thereby enhancing the overall shock absorption and cushioning performance of the landing gear.
