[0020] The following provides a detailed description of the present utility model in conjunction with the embodiments shown in the drawings:
[0021] The air spring semi-roll and shock absorber installation tooling includes: a frame 2, an adjustment mechanism 1, and a sealing bottom support 3.
[0022] The frame 2 has an installation bottom plate 21 and an installation top plate 22 arranged in the horizontal direction, and installation side plates 23 arranged vertically between the installation bottom plate 21 and the installation top plate 22. The installation top plate 22 is arranged above the installation bottom plate 21, and the installation side plates 23 are perpendicular to the installation bottom plate 21;
[0023] The adjustment mechanism 1 includes a number of adjustment holes 24 formed on the installation side plates 23 and arranged vertically from top to bottom, an adjustment plate 11 adjustably installed on the installation side plates 23 through bolt assemblies and the adjustment holes 24, and a pressing assembly 12 installed on the installation top plate 22 and capable of telescoping up and down.
[0024] The adjustment plate 11 is provided with a guide hole 13 located below the pressing assembly 12. The guide hole 13 is in the shape of a semi-circle with an open side. In this embodiment, it is an open semi-circle, which is convenient for the air spring 0 to be loaded from the side. The installation bottom plate 21 is provided with a limit bottom hole 24. At least a part of the limit bottom hole 24 is located within the projection of the guide hole 13 on the installation bottom plate 21, and this part is the first hole section. At least a part of the limit bottom hole 24 is located outside the projection of the guide hole 13 on the installation bottom plate 21, and this part is the second hole section. When the air spring 0 is placed on the second hole section, it is separated from the guide hole 13. The air spring 0 can be first placed on the second hole section of the installation bottom plate 21, and then the air spring 0 is pushed from the side towards the first hole section. Since the guide hole 13 is an open semi-circle, it is convenient for the air spring 0 to be loaded from the side.
[0025] The pressing assembly 12 includes a screw rod 14 threadedly connected to the installation top plate 22, an upper flange 15 rotatably connected to the lower end of the screw rod 14, and an upper end sealing head 16 with an upper end matching the upper flange 15 and fixedly connected through a bolt assembly. There are multiple upper end sealing heads 16. The lower end of each upper end sealing head 16 corresponds to a type of air spring 0, and the lower end of the upper end sealing head 16 is hermetically fixed on the upper end surface of the air spring 0.
[0026] The sealing bottom support 3 successively includes a core column 31, a support section 32, and a base plate 33 from top to bottom. The outer diameter of the core column 31 matches the inner diameter of the lower end of the air spring 0, and it passes through the lower end of the air spring 0. The lower end of the base plate 33 is fixed on the installation bottom plate 21 and fixedly connected through a bolt assembly.
[0027] The working principle of the present utility model is as follows: The lower end of the air spring 0 is fixed on the mounting base plate 21, and the upper end leans on or passes through the guiding hole 13. After inflating the air spring 0, by rotating the screw rod 14, the upper flange 15 is driven to move downward. Since the upper flange 15 is rotatably connected to the lower end of the screw rod 14, the upper flange 15 will not rotate and only moves downward. The upper end sealing head compresses the air spring 0 downward from the upper end of the air spring 0, causing the part of the air spring 0 filled with compressed air to bulge outward to form a semi-rolled state. After deflating, the shock absorber can be sent into the air spring 0 from the lower end of the air spring 0 to complete the installation.
[0028] The above embodiments are only used to illustrate the technical concept and features of the present utility model, and the purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly, and it should not be used to limit the protection scope of the present utility model. Any equivalent changes or modifications made according to the spirit of the present utility model should be covered within the protection scope of the present utility model.
