Tool for support assembly on radiator pull rod and using method thereof

Abstract

The invention discloses a tool for a support assembly on a radiator pull rod and a using method thereof. The tool comprises a supporting frame, a die and a fixing block, wherein the die is fixedly connected to the upper end of the supporting frame, and the fixing block is fixed at the lower end of the supporting frame; a limiting column and a limiting bulge are arranged on the upper surface of thedie, the two ends of the die are connected to L-shaped fixing blocks through shaft pins, the support assembly on the radiator pull rod is placed on the die, and through holes in the support assemblyon the radiator pull rod are sequentially placed on the limiting column and the limiting bulge; and the L-shaped fixing blocks are rotated, the support assembly on the radiator pull rod is fixed on the upper surface of the die, a nut penetrates through the limiting bulge to be connected to the upper surface of the support assembly on the radiator pull rod, and welding is carried out after connection. According to the tool and the using method, through the arrangement of the device, the welding procedures of the support assembly on the radiator pull rod is greatly simplified, the welding deformation of the support assembly on the radiator pull rod is reduced, due to the limiting bulge, the positioning of the nut is ensured to be accurate, so that the support assembly on the radiator pull rod is convenient to install at the later stage.

Description

technical field [0001] The invention relates to the technical field of automobile brackets, in particular to a tooling used for a bracket assembly on a radiator tie rod and a method for using the same. Background technique [0002] During automobile manufacturing, especially the radiator on heavy-duty commercial vehicles, the bracket needs to be fixed on the body. Since the bracket itself is in a Z shape, it needs to be bent. It is difficult to keep the angle of the bent part consistent during bending, so a mold is required to bend it. The shape after bending is tested. At the same time, in order to facilitate the fixing of the radiator, a nut needs to be welded on one end of the bracket. However, the bracket itself is simple in structure and small in size and is suitable for mass production. Due to mass production, if the positioning of the nut is not accurate, it is easy to cause the bracket If the radiator is damaged in batches or cannot be fixed well, it will affect the ...

[0002] During automobile manufacturing, especially the radiator on heavy-duty commercial vehicles, the bracket needs to be fixed on the body. Since the bracket itself is in a Z shape, it needs to be bent. It is difficult to keep the angle of the bent part consistent during bending, so a mold is required to bend it. The shape after bending is tested. At the same time, in order to facilitate the fixing of the radiator, a nut needs to be welded on one end of the bracket. However, the bracket itself is simple in structure and small in size and is suitable for mass production. Due to mass production, if the positioning of the nut is not accurate, it is easy to cause the bracket If the radiator is damaged in batches or cannot be fixed well, it will affect the fixing and installation of the radiator on the one hand, and on the other hand, the batch damage to the bracket will increase the production cost; at the same time, when the bracket is welded, it is necessary to check the outer circumference of the nut and the bracket. The contact surface is fully welded. When the welder is fully welded, the welder needs to rotate the nut for a circle before the nut can be fully welded on the bracket. Therefore, it also causes many problems such as inconvenient welding and fatigue of the welder. In addition, it is easy to cause problems when welding the nut. The deformation of the bracket, for example, the bracket is not well fixed during the welding process. After the welding is completed, the bracket is affected by the welding stress, causing warping and deformation of the welding part of the bracket, which affects the quality of the bracket itself. At the same time, based on the mass production of the bracket, the bracket The influence of the warping deformation of the welding part cannot be underestimated
