Description

Technical Field

[0001] This utility model relates to the field of dust collector manufacturing, and more particularly to a welding fixture for the intermediate partition plate and flap valve of a compartment dust collector. Background Technology

[0002] A compartmentalized dust collector is a highly efficient dust removal device. Its structural design typically includes multiple dust collection chambers, each equipped with key components such as an inlet, outlet, and filter bags or cartridges. The intermediate partitions, as crucial components separating the different dust collection chambers, significantly impact the overall performance of the dust collector due to their structural stability and sealing performance. Simultaneously, the flap valve, as an important part of the dust collector's ash discharge system, is also a key factor in ensuring the normal operation of the dust collector due to its flexible opening and closing and excellent sealing.

[0003] During the production process, it is necessary to weld the partitions together and the flap valve base to ensure the structural stability and strength of the intermediate partitions and flap valves, thereby improving the service life and reliability of the dust collector.

[0004] Existing welding fixtures have a high degree of automation, which reduces errors and uncertainties caused by manual operation and improves production efficiency. However, the welding fixtures lack a certain degree of stability and consistency during the clamping process, resulting in insufficient fixing force. Displacement occurs during welding, affecting the welding effect and thus reducing the welding quality of the product. Summary of the Invention

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] A preferred embodiment of the welding fixture for the intermediate partition plate and flap valve of the compartment dust collector provided by this utility model is as follows: Figures 1 to 4 As shown: A welding fixture for a partition plate and flap valve in a compartment dust collector includes two support columns 1. A worktable 5 is fixedly connected to the top of the two support columns 1. Four fixing components 3 are symmetrically fixed on both sides of the worktable 5. Clamping components 2 are symmetrically fixed on the front and rear parts of the top of the worktable 5. Four cooling components 4 are symmetrically fixed on the four corners of the top of the worktable 5.

[0026] In this embodiment, the fixing component 3 includes a second cylinder 309. The top end of the second cylinder 309 is fixedly connected to a support body 308 by screws. The telescopic end of the second cylinder 309 is fixedly connected to a U-shaped block 310. The outer wall of the U-shaped block 310 is rotatably connected to a support handle 302. The bottom end of the support handle 302 is rotatably connected to a first connecting block 303. The bottom end of the first connecting block 303 is rotatably connected to a protrusion 304. The protrusion 304 is fixedly connected to the top end of the support body 308.

[0027] Through the above scheme, the second cylinder 309 is used to drive the extension and retraction of its telescopic rod, thereby causing the U-shaped block 310 to drive the support handle 302 to rotate around the first connecting block 303. The end of the first connecting block 303 away from the support handle 302 rotates around the protrusion 304, providing power for the welding work.

[0028] In this embodiment, a first L-shaped block 305 is symmetrically fixed to both sides of the support body 308 by screws. The first L-shaped block 305 is fixedly connected to the front end of the worktable 5 by screws. A connecting block 307 is fixedly connected to the rear end of the support body 308. A second L-shaped block 306 is symmetrically fixed to both sides of the connecting block 307 by screws. The second L-shaped block 306 is fixedly connected to the bottom end of the worktable 5 by screws.

[0029] The above solution, by setting the first L-shaped block 305, the second L-shaped block 306 and the connecting block 307, not only fixes the support body 308 and improves its stability, but also facilitates disassembly and assembly. The fixing component 3 can be removed at any time for cleaning or replacement, providing convenience for staff.

[0030] In this embodiment, a fixing block 301 is rotatably connected to the top of the support handle 302.

[0031] With the above solution, the fixing block 301 is made of Q235 low carbon steel, which has good welding performance and plasticity, and is suitable for welding work of frames such as partitions.

[0032] In this embodiment, the clamping component 2 includes a first cylinder 201, which is fixed to the top of the workbench 5, and a clamping block 205 is fixedly connected to the driving end of the first cylinder 201.

[0033] Through the above scheme, the first cylinder 201 drives the clamping block 205 to move, and the two clamping components 2 work together to make the two clamping blocks 205 initially clamp and stabilize the partition or flap valve assembly.

[0034] In this embodiment, a housing 202 is fixedly connected to the top of the workbench 5. Two sliding grooves 203 are symmetrically opened through both sides inside the housing 202. Sliding rods 204 are slidably connected to the inner wall of the sliding grooves 203. A locking block 206 is fixedly connected to one end of the sliding rod 204. The ends of the two sliding rods 204 away from the locking block 206 are fixedly connected to the clamping block 205.

[0035] By using the above scheme, the displacement of the clamping block 205 is made more stable by using two sliding rods 204, and at the same time, the reaction force of the clamping force on the driving end of the first cylinder 201 can be shared, thereby improving the service life.

[0036] In this embodiment, the cross-sectional area of ​​the card block 206 along the vertical direction is equal to the cross-sectional area of ​​the rear end of the slide groove 203 along the vertical direction, and is greater than the cross-sectional area of ​​the front end of the slide groove 203 along the vertical direction.

[0037] The above solution prevents the slide bar 204 from detaching from the slide groove 203, thus avoiding problems for the clamping block 205 during the clamping process.

[0038] In this embodiment, the cooling component 4 includes a connecting cylinder 401. The bottom end of the connecting cylinder 401 passes through the workbench 5 and is connected to an external cold water tank. A valve 404 is fixedly provided on one side of the connecting cylinder 401. A pipe 402 is connected to the top end of the connecting cylinder 401, and a nozzle 403 is connected to the top end of the pipe 402.

[0039] With the above solution, the weld will remain at a high temperature after welding. Rotating valve 404 allows external cold water to be transported through pipe 402 and finally sprayed onto the weld surface from nozzle 403, which can achieve the purpose of rapid cooling and thus improve work efficiency.

[0040] Working principle: When operating and using this utility model, as follows... Figures 1 to 4 As shown, during use, the dust collector baffle or flap valve to be welded is placed on the top of the workbench 5. Then, the first cylinder 201 drives the clamping block 205 to move. The two clamping components 2 work together to make the two clamping blocks 205 initially clamp and stabilize the baffle or flap valve assembly and position it. Then, the second cylinder 309 drives the extension and retraction of its telescopic rod, so that the U-shaped block 310 drives the support handle 302 to rotate around the first connecting block 303. The end of the first connecting block 303 away from the support handle 302 rotates around the protrusion 304, so that the fixing block 301 firmly fixes the baffle or flap valve base. After welding is completed, the valve 404 is rotated so that external cold water is transported through the pipe 402 and finally sprayed onto the weld surface from the nozzle 403, which can achieve the purpose of rapid cooling.

[0041] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
