Detailed Description

The technical scheme of the disclosure will be described in detail with reference to the accompanying drawings. In the description of the present disclosure, it is to be understood that the terms "top," "bottom," "left end," "near," "middle," "through," and the like, indicate orientations and positional relationships based on the orientations and positional relationships shown in the drawings, are only for convenience in describing the present disclosure and simplifying the description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be taken as limiting the present disclosure.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated, but merely as differentiating between different elements.

In addition, unless expressly stated or limited otherwise, the terms "connected" and "attached" are to be construed broadly, e.g., as meaning a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; the connection may be direct or indirect via an intermediate medium, and may be a communication between the two elements. The specific meaning of the above terms in the present disclosure can be understood in specific instances by those skilled in the art.

The utility model discloses a special welding set for part among diesel engine aftertreatment urea level sensor, its schematic structure is shown in fig. 1, and the device includes first motor 1, second motor 2, support frame 8 and base 7, and support frame 8 establishes the left end at base 7 top, and first motor 1 establishes on support frame 8, and second motor 2 establishes the bottom at base 7, as shown in fig. 2, fig. 3. The welding gun 3 is arranged at the bottom of the first motor 1 in the direction close to the base 7, and the welding head 4 is arranged at the bottom of the welding gun 3. The top of the base 7 is provided with a turntable 5, the turntable 5 is connected with the second motor 2, and the turntable 5 is provided with at least one base 6. Several discs 9 can be placed on the base 6 and after starting the welding, the welding head 4 welds four inner studs 10 at the designated positions of the discs 9, as shown in fig. 4.

As a specific embodiment, the supporting frame 8 includes a vertical column 800 and a top plate 801, the top plate 801 is square, triangular or semicircular, the top plate in the embodiment of the present disclosure is square, and the number of the vertical columns 800 is 2, as shown in fig. 1.
