Description

Technical Field

[0001] The utility model relates to the technical field of mixer manufacturing, in particular to a clamping mechanism for welding and forming a cover plate for an automotive mixer. Background Art

[0002] According to relevant specifications, the exhaust gas generated during the operation of a diesel engine inside an automobile needs to be treated for harmful substances before being discharged. In the prior art, the exhaust gas sequentially passes through a D0C unit, a DPF unit, a mixer, and an SCR unit to remove harmful substances in the automobile exhaust gas. When the exhaust gas enters the mixer, the air flow is mixed with urea spray inside the mixer and then enters the SCR unit.

[0003] During the production of the mixer, a lower cover plate with a semi-circular cross-section needs to be welded to the surface of the upper cover plate. Since the internal space of the mixer is narrow, during the welding process, the position between the lower cover plate and the upper cover plate is prone to deviation, and there are differences in various aspects such as the size and angle of the welded cover plate, reducing the welding quality.

[0004] Therefore, it is necessary to provide a new clamping mechanism for welding and forming a cover plate for an automotive mixer to solve the above technical problems. Summary of the Utility Model

[0007] Preferably, connecting sleeves are symmetrically installed on the side wall of the support frame, guide rods are slidably connected inside the connecting sleeves, and the top ends of the guide rods are fixedly connected to the fixed plate.

[0008] Preferably, a first hydraulic rod is installed on the surface of the support frame, and a rubber sleeve is installed at one end of the first hydraulic rod.

[0009] Preferably, a limiting hole is provided on the side wall of the mixer, and the rubber sleeve is clamped inside the limiting hole.

[0010] Preferably, a pipe body is welded inside the mixer, an upper cover plate is welded to the side wall of the pipe body, and the lower cover plate is welded to the side wall of the upper cover plate.

[0011] Preferably, the surface area of the magnet is larger than that of the electromagnet, and the magnet is located between two rows of the electromagnets.

[0012] Preferably, the side wall of the fixed sleeve is provided with scale lines.

[0013] Compared with the related art, the clamping mechanism for welding and forming the cover plate for an automotive mixer provided by the present utility model has the following beneficial effects:

[0014] The present utility model provides a clamping mechanism for welding and forming the cover plate for an automotive mixer. When welding the lower cover plate, first, invert the mixer on the surface of the fixed seat, place the lower cover plate inside the fixed sleeve. The magnet at the center inside the fixed sleeve adsorbs the lower cover plate. Through the scale lines on the side wall of the fixed sleeve, move the lower cover plate inside the fixed sleeve so that the lower cover plate reaches the designed installation position. And at this time, only the magnet inside the fixed sleeve has magnetism, which not only ensures that the lower cover plate is fixed inside the fixed sleeve but also facilitates the adjustment of the position of the lower cover plate inside the fixed sleeve. When the position of the lower cover plate is determined, turn on the electromagnet inside the fixed sleeve, and the electromagnet generates magnetic force to adsorb the lower cover plate, stably fixing the lower cover plate inside the fixed sleeve. Turn on the second hydraulic rod, and the second hydraulic rod drives the fixed sleeve and the lower cover plate to move downward, so that the lower cover plate enters the inside of the mixing tube, and the lower cover plate is tightly pressed against the surface of the upper cover plate, preventing the position of the lower cover plate from shifting during the welding process and improving the welding quality of the lower cover plate.
