Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a self-cleaning welding machine for processing a volute of a centrifugal fan. Background Art
[0002] In the field of processing centrifugal fan volutes, the welding process has always been a key link in determining product quality. However, existing welding machines have some significant problems during use.
[0003] As for the fixed clamping link during welding, the existing devices also have significant shortcomings. Due to the uneven clamping force and poor stability, the volute is very likely to shake and displace during the welding process. This not only directly affects the welding accuracy and quality, resulting in defects such as uneven welds, pores and slag inclusions, but also seriously restricts the improvement of production efficiency. Improper clamping methods may also damage the surface of the volute, increasing the cost of subsequent processing and repair.
[0004] For example, a welding device for rectangular tube processing with announcement number CN222243284U includes a base and a slide, the slide is opened at the top of the base, and a clamping mechanism and a welding mechanism are arranged at the top of the base. The welding device for rectangular tube processing can stably weld different positions of the rectangular tube by setting the welding mechanism, and can eliminate the fume generated by welding during the welding process, thereby improving the welding environment. In the use of the above-mentioned welding device, there are deficiencies in the fixed clamping of the volute, which causes the volute to shake and displace easily during the welding process, but there are other problems in it. For example, as far as the welding slag generated during the welding process is concerned, the traditional treatment method has obvious disadvantages. The welding slag will not only accumulate on the surface of the volute in large quantities, seriously affecting the flatness and smoothness of its appearance, but also may penetrate into the welding gap, resulting in a decrease in welding strength and the inability to ensure dimensional accuracy. The random scattering of welding slag not only causes the working environment to be extremely dirty and messy, increases the difficulty and cost of cleaning, but also has safety hazards such as causing fire. The welding slag that has not been effectively collected also causes a waste of precious material resources, which is not in line with the concept of sustainable development. Utility Model Content

[0012] Further, a collection pipe penetrates through the right end of the protective housing, and a collection head is fixedly installed at the other end of the collection pipe and corresponds to the volute body.
[0013] Compared with the prior art, the beneficial effects of the present utility model are: The welding machine for processing the self-cleaning centrifugal fan volute;
[0014] 1. After the driving machine starts, it drives the guide block to move. Due to the structure of the guide block and the guide plate, the guide block slides forward along the guide plate, driving the fixed plate to move forward. The protective pad on the fixed plate contacts the volute body and fixes the volute body by friction. At the same time, the protective pad prevents scratches on the surface of the volute body, aligns the welding machine body with the place where the volute body needs to be welded, ensures accurate welding, improves the quality of welded products, reduces the rejection rate, and reduces the risk of accidents.
[0015] Furthermore, with excellent clamping accuracy and stability, it ensures that the position of the volute remains motionless during the welding process, thus achieving perfect uniformity of the weld seam, greatly improving the reliability and stability of welding quality, effectively eliminating the vibration influence during the welding process, significantly reducing the welding residual stress, fundamentally extending the service life and reliability of the volute, and being able to easily handle centrifugal fan volutes of various specifications, shapes, and materials to meet diverse production requirements.
[0016] Moreover, the reliable clamping device provides a safe and worry-free working environment for operators, eliminates various safety accidents caused by clamping failure, safeguards the lives of personnel, can effectively reduce welding deformation, reduce the difficulty and cost of subsequent correction processes, improve the overall production efficiency, reduce the pressure on the surface of the volute, avoid causing indentations or damage, and ensure the integrity and aesthetic appearance of the volute.
[0017] 2. The motor drives the impeller inside the protective housing to rotate, so that under the suction force generated by the impeller, the welding slag residues are adsorbed and collected by the collection head at the upper end of the collection pipe. Then the welding slag residues enter the interior of the transfer pipe along the collection pipe, and then the transfer pipe transports the welding slag residues to the interior of the collection box. The filter screen set inside the collection box can effectively prevent the welding slag residues from being blown out of the air outlet pipe along with the air flow, ensuring that every corner of the volute is clean and tidy, making its appearance quality reach the extreme, and greatly enhancing the market attractiveness of the product.
[0018] Furthermore, it minimizes environmental pollution to the greatest extent, lays a solid foundation for subsequent environmental protection treatment and resource recycling, effectively avoids thermal damage to the surface of the volute caused by high-temperature welding slag, safeguards the physical properties and service life of the volute, the highly automated welding slag cleaning and collection system reduces the labor intensity of workers, significantly improves production efficiency, reduces production costs, and the orderly collection and classified management of welding slag provide strong support for the enterprise to achieve lean production and cost control, enhancing the market competitiveness of the enterprise.

[0027] Embodiment 1: Please refer to Figures 1-6, the present utility model provides the following technical solutions: A welding machine for processing a self-cleaning centrifugal fan volute, including a frame 1 and an adjustable column 2 fixedly installed at the rear of the upper end of the frame 1; a welding machine body 3 is fixedly installed at the front end of the adjustable column 2 when it is activated. A motor 4 is installed at the lower end of the frame 1, and a rotating disk 5 is fixedly installed at the output end of the motor 4. The rotating disk 5 is installed at the upper end of the frame 1. A guide plate 6 is fixedly installed at the upper left end of the rotating disk 5. The guide plate 6 is a "T"-shaped plate, and two guide plates 6 are evenly distributed around the rotating disk 5 as the rotation center. A clamping mechanism is arranged at the upper end of the rotating disk 5, and a guide block 7 is arranged at the upper left end of the rotating disk 5. The guide plate 6 and the guide block 7 cooperate with each other; a protective shell 8 is fixedly installed at the lower end of the frame 1, and the motor 4 is fixedly installed in the lower protective shell 8. An impeller 9 is fixedly installed at the output end of the motor 4, and the impeller 9 is installed inside the protective shell 8. A cleaning mechanism is arranged at the upper end of the frame 1, and a transfer pipe 10 penetrates and is installed at the left end of the protective shell 8. The clamping mechanism includes a pusher 11 fixedly installed at the upper left end of the rotating disk 5, and the output end of the pusher 11 is fixedly installed at the front end of the guide block 7. A fixing plate 12 is fixedly installed at the right end of the guide block 7. A protective pad 13 is adhesively installed above the right end of the fixing plate 12. A volute body 14 is arranged at the upper end of the rotating disk 5, and the volute body 14 is installed between the protective pads 13.

[0028] First, place the volute body 14 on the rotating disk 5. Then, start the pusher 11. After the pusher 11 is started, it drives the guide block 7 to move. Due to the structure of the guide block 7 and the guide plate 6, the guide block 7 slides forward along the guide plate 6, driving the fixing plate 12 to move forward. The protective pad 13 on the fixing plate 12 contacts the volute body 14 and fixes the volute body 14 by friction.

[0030] The motor 4 drives the impeller 9 inside the protective housing 8 to rotate, so that under the suction force generated by the impeller 9, the welding slag residue is adsorbed and collected by the collecting head 21 at the upper end of the collecting pipe 20. Then, the welding slag residue enters the inside of the transfer pipe 10 through which it is transferred along the collecting pipe 20. Next, the transfer pipe 10 conveys the welding slag residue into the inside of the collecting box 17, and the filter screen 18 provided inside the collecting box 17 can effectively prevent the welding slag residue from being blown out from the air outlet pipe 19 along with the air flow.
