[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0021] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., 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, the above terms should not be construed as a limitation of this utility model.

[0022] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0023] like Figures 1-5 The present invention provides a landing gear auxiliary assembly device, including a base 1 and a support frame 2 movably mounted on the base 1. A positioning frame 3 is provided on the side of the support frame 2. The upper part of the positioning frame 3 has a positioning ring 4, and the lower part of the positioning frame 3 has a ball socket support 5 that matches the bottom of the landing gear, so that when the landing gear is located in the positioning ring 4, the bottom of the landing gear is mounted on the ball socket support 5.

[0024] The base provides stable support for the support frame. Combined with the movable setting of the support frame and the lifting and lowering adjustment of the positioning frame, the height and horizontal position of the landing gear can be flexibly adjusted through the cooperation of the positioning frame and the support frame when it is installed in the positioning ring. At the same time, the ball joint supports provide fulcrum support for the bottom of the landing gear, improving the stability of the landing gear in the positioning ring.

[0025] Preferably, the positioning frame 3 is movably provided with an adjustment plate 6 on its side, the rotating support 7 is rotatably connected to the adjustment plate 6, and the positioning ring 4 is connected to the rotating support 7, so that when the adjustment plate 6 moves along the positioning frame 3, the landing gear tilts with the ball joint support 5 as the fulcrum.

[0026] Specifically, when the bottom of the landing gear is mounted on the ball joint support, as the adjusting plate moves along the positioning frame, the positioning ring will simultaneously drive the upper part of the landing gear to move horizontally, thereby causing the landing gear to tilt with the ball joint support as the fulcrum, realizing flexible adjustment of the landing gear attitude and meeting the assembly requirements under different installation angles.

[0027] Meanwhile, since the swivel bearing can rotate relative to the adjusting plate, it can adaptively adjust its angle during the tilting of the landing gear with the ball bearing as the fulcrum, ensuring the stable positioning of the locating ring on the landing gear.

[0028] Preferably, the positioning ring 4 has a guide groove 8 on its side, the rotating support 7 has a guide post 9 that slides with the guide groove 8, and the rotating support 7 is provided with a fastener 10 so that after the positioning ring 4 rotates along the rotating support 7, the fastener 10 tightens the positioning ring 4.

[0029] Specifically, when it is necessary to adjust the circumferential angle of the landing gear, the fasteners can be loosened to allow the guide post to slide in the guide groove, thereby causing the positioning ring to rotate circumferentially relative to the rotating support. This will simultaneously adjust the circumferential angle of the landing gear. After the adjustment is completed, the fasteners can be tightened again to fix the circumferential angle position of the positioning ring and the rotating support. This allows for quick adjustment of the circumferential positioning of the landing gear to meet the needs of different assembly stations.

[0030] The fasteners can be bolts, and the fasteners and the rotating support are threaded together.

[0031] Preferably, the positioning ring 4 has an opening 11 on one side, and a positioning pin 12 is connected to the opening 11, and the positioning pin 12 matches the landing gear.

[0032] Specifically, the landing gear is moved to the positioning ring through the opening and then positioned. The positioning pins are then inserted through both sides of the opening and the matching position of the landing gear to lock and fix the landing gear to the positioning ring, preventing displacement or loosening during assembly.

[0033] The landing gear frame has a hole-like structure on its side that matches the positioning pin, so that the positioning pin can pass through the landing gear frame and connect the landing gear to the positioning ring.

[0034] Preferably, the support frame 2 is provided with a support plate 13 that moves horizontally along its side, and the positioning frame 3 is vertically connected to the support plate 13.

[0035] Specifically, through the horizontal movement of the support plate and the support frame, the positioning frame can drive the landing gear to adjust in at least three degrees of freedom, namely, planar movement along the X and Y axes and height adjustment along the Z axis. Combined with the rotation adjustment of the rotating support and the circumferential fine adjustment of the positioning ring, the landing gear can be accurately positioned in multiple dimensions of space.

[0036] Preferably, the base 1 has a plurality of casters 14 on its lower side, and the base 1 has a plurality of support legs 15 corresponding to the casters 14 on its side, and the support legs 15 are telescopic.

[0037] Specifically, the casters allow the base to move the landing gear to the appropriate assembly position, and then the support legs extend to the ground to provide stable support for the equipment and prevent positional displacement caused by the movement of the casters.

[0038] The extension and retraction of the support legs can be achieved by setting a threaded sleeve on the side of the base, connecting the support legs to the threaded sleeve, and adjusting the height by rotating the support legs, thereby adapting to different ground environments and ensuring the equipment is level and stable.

[0039] Preferably, a bubble level 16 is provided on the rotating support 7. In one embodiment of this solution, the bubble level is a level device used to detect the horizontal angle of the rotating support.

[0040] Preferably, the support frame 2 is provided with a handrail 17 on the side away from the positioning frame 3, so that the operator can push the base to transfer the landing gear by the handrail.

[0041] It is worth mentioning that in this solution, the movable connection between the base and the support frame, the movable connection between the support frame and the support plate, the lifting connection between the positioning frame and the support plate, and the movable connection between the adjusting plate and the positioning frame all adopt the sliding rail and screw drive form for movement control. Moreover, the screw can be driven by manual rotation control to ensure precise manual adjustment.

[0042] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
