[0029] Specifically, the main frame 1 serves as a supporting structure, and a base 2 is provided on the main frame 1. The base 2, which serves as a supporting structure, is arranged inclined so that the base 2 has an inclined surface. A pressing ring 3 is provided on the inclined surface. The pressing ring 3 is a hollow cylindrical structure. The top of the pressing ring 3 is an open structure. The bottom of the pressing ring 3 is fixedly connected to the inclined surface. The axis of the pressing ring 3 is perpendicular to the inclined surface. A through hole is provided at the center of the bottom of the pressing ring 3. A screw hole coaxially arranged therewith is provided on the base 2 at the lower part of the through hole. The pressing ring 3 is provided on the inclined surface, so the pressing ring 3 is inclined. A leakage port 7 is provided at the bottom of the lower end side of the pressing ring 3. The leakage port 7 connects the internal cavity of the pressing ring 3 with the outside.

[0030] A core shaft 6 is provided in the internal cavity of the pressing ring 3, and the core shaft 6 is coaxially arranged with the pressing ring 3. A screw 10 is provided at the bottom of the core shaft 6. The screw 10 passes through the through hole at the bottom of the pressing ring 3 and is threadedly connected to the screw hole of the base 2, so that the core shaft 6 is fixed inside the pressing ring 3, and the core shaft 6 can rotate inside the pressing ring 3.

[0031] A convex ring 8 is also provided on the top of the pressing ring 3. The convex ring 8 is a circular ring structure with the same inner diameter as the pressing ring 3. The outer diameter of the convex ring 8 is smaller than the pressing ring 3. The convex ring 8 and the pressing ring 3 are coaxially arranged. The annular cavity between the convex ring 8 and the core shaft 6 is used to place the flange 5. After the flange 5 is placed, the inner wall of the flange 5 fits with the outer wall of the core shaft 6 to achieve positioning and fixation of the flange 5. The flange 5 can rotate with the core shaft 6. The dust cover 4 is placed on the convex ring 8, and the inner wall of the dust cover 4 fits with the outer wall of the convex ring 8 to achieve fixation and positioning of the dust cover 4.

[0032] A positioning mechanism is also provided on the inclined surface of the base 2, and the positioning mechanism is arranged on the inclined surface of the side of the pressure ring 3. The positioning mechanism includes a positioning rod 9 rotatably arranged on the inclined surface. The number of the positioning rod 9 is at least one, and the positioning rod 9 is an L-shaped rod. The positioning rod 9 is arranged perpendicular to the inclined surface so that the rod section on its upper part is parallel to the inclined surface, and when the dust cover 4 and the flange 5 are placed on the tooling, the end of the upper rod section of the positioning rod 9 is close to the welding place between the flange 5 and the dust cover 4. The positioning rod 9 is used to provide a position reference for the welding point between the dust cover 4 and the flange 5. When the number of positioning rods 9 is one, the dust cover 4 and the flange 5 at the positioning rod 9 are welded, and then the flange 5 and the dust cover 4 are rotated, and the previous welding point is used as a reference to make the positioning rod 9 and the previous welding point misaligned by a corresponding angle. When multiple positioning rods 9 are provided, multiple The positioning rod 9 is set in a circle with the same center as the pressure ring 3, and the offset angle between two adjacent positioning rods 9 can be set according to the number of welding points. For example, when the number of positioning rods 9 is three, the first and second positioning rods 9 can be offset by thirty degrees, and the second positioning rod 9 and the third positioning rod 9 can be offset by sixty degrees. According to the number of welding points, if the welding points are to be arranged with a thirty-degree offset, only the first positioning rod 9 and the second positioning rod 9 need to be used. If the welding points need to be offset by sixty degrees, the second positioning rod 9 and the third positioning rod 9 can be used. Since the positioning rod 9 is rotatably set on the inclined plane, when the dust cover 4 is placed, the positioning rod 9 can be rotated so that the upper rod section of the positioning rod 9 faces outward to prevent the positioning rod 9 from interfering with the placement of the dust cover 4, and the rotating friction pair of the positioning rod 9 is adjusted so that its rotation has a certain resistance.

[0033] The present invention can quickly fix and position the flange 5 and the dust cover 4. The flange 5 fits with the welding surface of the dust cover 4 placed on the convex ring 8 by its own weight on the tooling. The reference of the welding point position is realized by the positioning mechanism, and the flange 5 and the dust cover 4 can be quickly welded to improve production efficiency.

[0036] In this embodiment, a corresponding number of screws 10 can be set at corresponding positions according to the number of common welding points between the dust cover 4 and the flange 5. According to different welding points, positioning rods 9 can be placed on the corresponding screws 10. Compared with embodiment 1, the positioning mechanism of this embodiment can be applicable to welding operations with a variety of welding points, with a wider range of uses and simple operation. In addition, unused positioning rods 9 are easy to remove and do not hinder the welding of the flange 5 and the dust cover 4.
