Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and particularly relates to a pre-installed tire for a heavy truck gas cylinder frame assembly. Background Art

[0002] The heavy truck gas cylinder frame assembly is composed of multiple parts. After the multiple parts are welded, they need to be assembled and welded into a heavy truck gas cylinder frame assembly. Most assembly welding uses simple tooling for positioning, which results in low welding efficiency, poor product consistency, and difficulty in controlling the size within the tolerance range, affecting the overall production progress and product quality of the company's products;

[0003] There are some gas cylinder frame welding tools in the prior art, but they are not universal due to the great structural differences between gas cylinder frames of different manufacturers. For example, CN109570863A gas cylinder transport vehicle frame welding tool is not suitable for welding of heavy truck gas cylinder frame monomers. Utility Model Content

[0004] The utility model provides a pre-installed tire for a heavy truck gas cylinder frame assembly, which can solve the problems pointed out in the background technology.

[0005] A pre-installed tire for a heavy truck gas cylinder frame assembly comprises a bottom platform, a lower support plate positioning assembly is arranged in the middle of the bottom platform, the lower support plate positioning assembly comprises a rectangular limit frame, and first positioning columns are arranged at the four corners of the rectangular limit frame, a limit groove is arranged on one side of the rectangular limit frame on one side in the width direction, and a limit vertical plate is arranged at the inner side of the limit groove; lower arc plate positioning assemblies are arranged on both sides of the width direction of the rectangular limit frame, the lower arc plate positioning assembly comprises a lower arc plate positioning seat, an arc-shaped limit groove is arranged at the upper end of the top of the lower arc plate positioning seat, and lower corner plate positioning assemblies are arranged on both sides of the length direction of the rectangular limit frame, The lower corner plate positioning assembly includes a right-angle positioning groove and a second positioning column located at both ends of the right-angle positioning groove in the width direction. Bottom beam positioning assemblies are respectively provided on both sides of the length direction of the lower arc plate positioning seat. The bottom beam positioning assembly includes a bottom beam positioning seat and a third positioning column arranged on the top of the bottom beam positioning seat. Upper arc plate positioning assemblies are respectively provided on the outer sides in the length direction of the right-angle positioning groove. The upper arc plate positioning assembly includes a support frame and flip positioning pieces located at both ends of the support frame in the width direction. The flip positioning piece is movably connected to the support frame so that it can be flipped to the limit position for limiting. A fourth positioning column is provided on the flip positioning piece.

[0006] Preferably, the flip positioning member is rotatably connected to the support frame via a rotating seat.

[0007] Beneficial effects: The utility model provides a pre-installed tire for a heavy truck gas cylinder frame assembly, which can be suitable for welding operations of the heavy truck gas cylinder frame assembly, can improve production efficiency and welding accuracy, thereby reducing production costs and improving product quality.
