Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a clamping device for welding and forming a bent pipe heat insulation cover for an automobile mixer. Background Technique

[0002] As an important part of urban logistics and transportation, while serving the economic construction, the exhaust emissions of automobiles have become an important factor affecting air quality. To ensure the compliance of exhaust emissions, catalytic converters are used to reduce exhaust pollution. Existing catalytic converters mostly use DOC+DPF+mixer+SCR to remove harmful substances in automobile exhaust. The main function of the mixer is to break up urea so that the exhaust gas and urea are fully mixed and then enter the SCR.

[0003] Since the exhaust gas generated by automobiles is at a high temperature, during the production of the mixer, a heat insulation cover needs to be welded on the outside of the mixer. However, since the surface of the mixer is in the shape of a bent pipe, during the splicing process of the heat insulation cover and the mixing pipe, the bent end of the mixer is prone to rotate downward, resulting in deviation during the docking process of the mixing pipe and the heat insulation cover, reducing the welding quality of the heat insulation cover.

[0004] Therefore, it is necessary to provide a new clamping device for welding and forming a bent pipe heat insulation cover for an automobile mixer to solve the above technical problems. Content of the Utility Model

[0005] The technical problem solved by the utility model is to provide a clamping device for welding and forming a bent pipe heat insulation cover for an automobile mixer, which is convenient for accurately splicing the mixing pipe and the heat insulation cover and improves the welding quality.

[0006] To solve the above technical problems, the clamping device for welding and forming a bent pipe heat insulation cover for an automobile mixer provided by the utility model includes: a base, a third clamping seat and a fourth clamping seat with an arc-shaped side wall are installed on the surface of the base, and a support seat for fixing a cylinder is installed on the surface of the base; one end of the cylinder is installed with a fixed shell, and a clamping plate is rotatably connected to the surface of the fixed shell; the top ends of the first clamping seat and the support plate are fixedly connected to the clamping plate; the bottom ends of the support plates are symmetrically and fixedly connected to the second clamping seats; the lower heat insulation cover is clamped inside the third clamping seat and the fourth clamping seat, the upper heat insulation cover is clamped inside the first clamping seat and the second clamping seat, and the mixer bent pipe is clamped between the upper heat insulation cover and the lower heat insulation cover.

[0007] Preferably, two cylinders are arranged above the base, and the two cylinders are arranged perpendicular to each other.

[0008] Preferably, the centers of the third clamping seat and the fourth clamping seat are located in the same plane, and the third clamping seat and the fourth clamping seat are arranged perpendicular to each other on the surface of the base.

[0009] Preferably, the first card seat is aligned with the fourth card seat, the second card seat is aligned with the third card seat, and rubber pads are installed inside the first card seat, the second card seat, the third card seat and the fourth card seat.

[0010] Preferably, a limiting plate is installed at one end of the base, and the limiting plate abuts against one end of the mixer elbow that is straight.

[0011] Preferably, a rotating shaft and a gear are rotatably connected inside the fixed shell. Both ends of the rotating shaft are fixedly connected to the clamping plates, and the side wall of the rotating shaft is fixedly connected to the gear.

[0012] Preferably, a rack is slidably connected inside the fixed shell. The rack meshes with the gear, and one end of the rack is connected to the cylinder.

[0013] Compared with the related art, the clamping device for welding and forming the elbow heat insulation cover of an automobile mixer provided by the present utility model has the following beneficial effects:

[0014] The present utility model provides a clamping device for welding and forming an elbow heat insulation cover of an automobile mixer. When welding the heat insulation cover on the surface of the mixer elbow, first place the lower heat insulation cover inside the third card seat and the fourth card seat. The bent end of the lower heat insulation cover is placed inside the third card seat. The side walls of the third card seat and the fourth card seat are arc-shaped, and the centers of the third card seat and the fourth card seat are located in the same plane. The third card seat and the fourth card seat are perpendicularly arranged on the surface of the base, so as to horizontally place the lower heat insulation cover inside the third card seat and the fourth card seat. Then, place the mixer elbow inside the lower heat insulation cover and the upper heat insulation cover in sequence. The fourth card seat provides support for the bent parts of the heat insulation cover and the mixer elbow, so as to facilitate the accurate splicing between the mixer elbow and the heat insulation cover and avoid deviation during the splicing process of the three. Open the cylinder, and the operation of the cylinder drives the first card seat and the second card seat to move downward, so that the first card seat and the second card seat squeeze the upper heat insulation cover downward, making the upper heat insulation cover closely adhere to the mixer elbow and the lower heat insulation cover, avoiding dislocation between the upper heat insulation cover and the lower heat insulation cover and the mixer elbow during the welding process and improving the welding quality.
