Description

Technical Field

[0001] This utility model relates to a tooling fixture, specifically to a welding fixture for soot blowing pipe assembly. Background Technology

[0002] The soot blowing pipe is a key component for the stable operation of a baghouse dust collector. Installed inside the upper housing of the dust collector, it is commonly used in the waste-to-energy industry. Existing soot blowing pipes typically consist of a soot blowing pipe body and an air blowing pipe body. After fabrication, the centerlines of all air blowing pipes must be in the same plane with a deviation of less than ±1mm, and their perpendicularity to the reference plane must be less than 1mm. If the air blowing pipes are misaligned, during pulse soot blowing, firstly, it will severely affect the soot blowing effect; secondly, it will cause direct erosion of the filter bags, reducing their service life and significantly increasing the operating costs of the power plant. The main problems in the existing soot blowing pipe fabrication are: 1. Because all welds are located on one side, the soot blowing pipe will bend and deform after assembly; 2. The centerlines of the air blowing pipes are not in the same plane, and the center distance exceeds the tolerance; 3. The air blowing pipe is not perpendicular to the reference plane A. To control welding deformation and ensure the accurate positioning of the air blowing pipes, a tooling must be fabricated to meet production requirements. Utility Model Content

Detailed Implementation

[0019] The embodiments of this utility model will be further described below with reference to the accompanying drawings: Depend on Figure 1Combination Figure 2-3 As shown, a welding fixture for soot blowing pipes includes a frame 1, and also includes: Support plate 2 is mounted on frame 1; Positioning component 3 is provided on support plate 2 and is used to fix soot blowing pipe 10; The upper template 4 is provided with positioning holes 41 that are adapted to the air blowing pipe 11. The upper template 4 has a first position during installation and a second position where the air blowing pipe 11 is pressed down and limited when inserted into the soot blowing pipe 10. The beneficial effects of this utility model are that a positioning component is provided for fixing and limiting the soot blowing pipe, and the upper template cooperates with the air blowing pipe to limit the air blowing pipe, thereby facilitating the assembly and welding of the soot blowing pipe and simplifying processing. This utility model also has the advantages of low manufacturing cost and simple and convenient operation, achieving economical and practical effects, and improving product quality and work efficiency. Products processed using this utility model tooling also have the following advantages: 1. The overall straightness of the blowing pipe is good, with very few instances of exceeding tolerances; 2. The center lines of each blowing pipe are all in the same plane, with a deviation generally of ±0.5mm; 3. The lower openings of each blowing pipe are all in the same plane, with a deviation generally of ±1mm; 4. The center distance of each blowing pipe is accurate, with a deviation generally of ±0.5mm. This utility model tooling is designed based on the principles of planar positioning, axial positioning, and rigid fixing. It also takes into account economic applicability. The overall manufacturing cost of the tooling is low, and it is simple and convenient to operate, achieving an economical and applicable effect, and improving product quality and work efficiency.

[0020] This utility model also includes a positioning tube 5, which passes through the air blowing tube 11. Specifically, the positioning tube 5 is a round tube, and it passes through multiple different air blowing tubes 11 so that the center lines of the different air blowing tubes 11 are on the same plane. By using a positioning tube with good straightness to pass through the side round holes of all air blowing tubes, the center lines of the air blowing tubes are ensured to be on the same plane. The overall straightness of the blowing tubes is good, with very few deviations. The center lines of each air blowing tube are all in the same plane, with a deviation generally of ±0.5mm.

[0021] There are multiple positioning holes 41, each corresponding to the air blowing pipe 11. When the upper template 4 is in the second position, the air blowing pipe 11 is inserted into the positioning hole 41 and its position is limited. The positioning holes of the upper template ensure that the center line of the air blowing pipe is in the same plane, and cooperate with the positioning pipe to achieve reliable positioning of the air blowing pipe, which facilitates subsequent processing.

[0022] This utility model also includes an adjusting plate 6 and a handle 7. The adjusting plate 6 is located above the upper template 4 and is used to press the upper template 4. The handle 7 is connected to the adjusting plate 6 and locks the upper template 4 through the adjusting plate 6. Specifically, this utility model also includes a guide post 8. The adjusting plate 6 is located on the guide post 8 and slides with the guide post 8. After locking the handle, the upper template is pressed by the adjusting plate. In fact, the frame is also equipped with a baffle (not shown in the figure). The baffle is stuck between the support plate and the upper template. The top of the baffle is consistent with the upper plane of the workpiece (air blowing pipe). After it is in place, it presses against the upper template, and the upper template cannot be pressed down further. The handle and the adjusting plate can reliably fix the air blowing pipe and ensure that the lower plane of the air blowing pipe is in the same plane. The locking force of the handle achieves the effect of rigid fixation. The air blowing pipe is welded by segmented skip welding. After the weld cools, the handle is released and the air blowing pipe is taken out, thus completing the assembly welding of the air blowing pipe. In fact, when the handle is turned, the adjusting plate and the upper template move simultaneously. The upper template is locked or unlocked by the handle.

[0023] Multiple adjustment plates 6 are provided above the upper template 4, and the multiple adjustment plates 6 are arranged sequentially along the axial direction of the soot blowing pipe 10. The handle 7 is provided with an operation part 71 for easy operation, and the operation part 71 is arranged parallel to the guide post 8. This structure facilitates handle operation, is simple in structure, facilitates the overall processing of the soot blowing pipe, and facilitates the welding of the soot blowing pipe by segmented skip welding, ensuring reliable product processing.

[0024] The positioning component 3 is provided with two insert portions 31, which cooperate with each other and are arranged with one end contracted and the other end open. This invention utilizes a straight channel steel (positioning component) to position the soot blowing pipe, ensuring both the straightness of the soot blowing pipe and facilitating its fixation. This allows the positioning component to be adapted to soot-eating pipes of different diameters, making soot blowing pipe positioning convenient and reliable, and improving product processing efficiency.

[0025] This utility model also includes a support leg 9, which is located below the support plate 2 for support, and the upper template 4 is located above the support plate 2. This structure facilitates operation.
