Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings by way of examples.
The embodiment provides a welding and positioning device for a connecting cylinder, which is used for positioning each part when the connecting cylinder is welded with a flow guide body and the connecting cylinder is welded with a flange plate, so that the welding requirement is ensured.
As shown in fig. 1 to 3, the positioning device includes: the positioning device comprises a base 1, a positioning block 2, a positioning plate 3 and a guide plate 7; the bottom of the positioning block 2 is fixedly arranged in the middle of the upper surface of the base 1; two opposite sides of the base 1 are respectively provided with a guide plate 7; the top of the bottom of the guide plate 7 is fixed on the base 1, and a bolt hole is processed at the top; the positioning plate 3 is fixedly supported on the top of the two guide plates 7 by bolts 4 and washers 5 which fit into bolt holes in the top of the guide plates 7.
Specifically, the method comprises the following steps: the structure of the positioning block 2 is shown in fig. 4, and the positioning block 2 comprises a rectangular block and a cylindrical block positioned on the bottom end face of the rectangular block; a round hole with the same size as the cylindrical block on the positioning block and a positioning groove coaxial with the round hole are processed at the center of the base 1, and the size and the shape of the positioning groove are the same as those of the connecting cylinder to be welded, so that the end part of the connecting cylinder supported on the base 1 is positioned; the positioning block 2 is arranged on the base 1 through the cylindrical block at the bottom of the positioning block and the round hole on the base 1 in an interference fit manner.
The structure of the positioning plate 3 is shown in fig. 5, wherein two ends of the positioning plate 3 extend out of support lugs for connecting with two guide plates 7 through bolts 4; the positioning plate 3 is provided with a central hole, and the outer circumference of the central hole is provided with a positioning hole for positioning connection with the flange plate.
When in use, one end of the connecting cylinder to be welded is supported on the base 1 through the positioning groove on the base 1, and the connecting cylinder is sleeved outside the positioning block 2; then, the flow guide body is placed on the upper surface of the positioning block 2, the distance between the upper surface of the positioning block 2 and the upper surface of the base 1 meets the set requirement, namely the requirement of the height position of the flow guide body relative to the connecting cylinder is ensured through the axial size of the positioning block 2 in the connecting cylinder; the flange plate is arranged on the positioning plate 3 through a positioning bolt 6 matched with the positioning hole, so that the top of the connecting cylinder to be welded extends into the flange plate, and the flange plate is ensured to be coaxial with the connecting cylinder to be welded through the position of the positioning bolt hole on the positioning plate 3; the end face of the flow guide body is ensured to be parallel to the end face of the flange plate through the positioning plate 3 and the positioning block 2. After the connecting barrel, the flow guide body and the flange plate to be welded are positioned, the flow guide body is directly welded at the connecting part of the flow guide body and the connecting barrel, so that the flow guide body is welded at a set height position in the connecting barrel; welding the connecting cylinder and the flange plate at the butted circumference to realize the connection of the connecting cylinder and the flange plate; the welded parts can not only ensure the requirement of the height position of the flow guide body in the connecting cylinder, but also ensure the parallelism between the end face of the flow guide body and the end face of the flange plate.
