Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment technology, and more specifically, to an anti-splashing device for welding aluminum alloy pipes. Background Technology

[0002] Aluminum alloy tubes refer to tubular structures made of aluminum alloy materials. They are lightweight, corrosion-resistant, and high-strength, and are widely used in aerospace, automotive, and construction industries. Welding aluminum alloy tubes often produces a large amount of spatter during the welding process.

[0003] Currently, blocking mechanisms are used to block spatter in the welding area, which serves to prevent spattering. However, these blocking mechanisms occupy space and affect welding operations, making it inconvenient to handle by hand. On the other hand, although the blocking mechanism does prevent spatter from splashing into the environment, the blocked spatter still falls near the welding area, interfering with the welding process. Overall, the effect is not good. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an anti-splash device for welding aluminum alloy tubes, which has the advantages of suction-type anti-splash and improved welding efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a splash-proof device for aluminum alloy tube welding, comprising a base and a protective cover. A top frame is fixedly provided on the top of the base, and a lifting mechanism is fixedly installed inside the top frame. The movable end of the lifting mechanism is fixedly connected to the protective cover. The protective cover is a ring-shaped structure with a notch. An observation window is provided on the front of the outer side of the protective cover, and an intake port is provided on the back of the outer side of the protective cover. The top of the intake port is connected to an intake pipe, and the top end of the intake pipe is connected to a filter collection section. An intake pump is connected above the filter collection section, and the filter collection section sucks in and collects the splashed metal particles inside.

[0006] As a preferred embodiment of this utility model, the filter collection part includes a collection frame, a filter frame, a partition plate, a through hole, and a sealing cover. The filter frame is movably sleeved into the inside of the collection frame along the end of the collection frame. The partition plate is fixed inside the filter frame. A filter hole is provided on the right side of the top of the filter frame. The through hole is opened on the left side of the bottom of the collection frame. A connecting hole corresponding to and communicating with the through hole is provided at the bottom of the partition plate. The sealing cover is fixedly connected to the outer end of the filter frame.

[0007] As a preferred embodiment of this utility model, the top of the base is fixedly provided with symmetrically distributed upright plates, and the inside of the upright plates is provided with a pipe fixing mechanism to fix the aluminum alloy pipe to be welded.

[0008] As a preferred embodiment of this utility model, the pipe fixing mechanism includes a collar, a clamping ring, a clamping mechanism, and an adjusting component. The collar is rotatably mounted in the vertical plate via a bearing. The clamping mechanism is fixed at the end of the collar and is distributed at equal intervals around the inner wall of the clamping ring. The adjusting component is connected and disposed on the outer side of the clamping ring.

[0009] As a preferred embodiment of this utility model, the clamping ring has an internal cavity, and the clamping mechanism includes a sleeve, a clamping rod and a spring. The sleeve is fixed on the inner wall of the clamping ring, the clamping rod is movably sleeved in the sleeve, one end of the spring is fixedly connected to the inner end of the clamping rod, and the other end of the spring is fixed in the cavity.

[0010] As a preferred embodiment of the present invention, the adjusting assembly includes a fixed sleeve and a piston part. The rod of the piston part is threadedly sleeved on the end of the fixed sleeve, and the movable end of the piston part is movably sleeved in the fixed sleeve. The fixed sleeve communicates with the ring cavity through a small hole opened on the outer side of the clamping ring.

[0011] As a preferred embodiment of this utility model, the base is provided with a drive deflection assembly, which controls the rotation of the pipe fixing mechanism. The drive deflection assembly includes a toothed plate, a connecting plate, an electric push rod, and a gear. The toothed plate is fixedly connected to the gear, and the gear is fixedly sleeved on the outside of the collar. The two toothed plates are connected as a whole by the connecting plate, and the movable end of the electric push rod is fixedly connected to the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model fixes and abuts the pipeline to be welded, and uses an operating lifting mechanism to move the protective cover down and cover the outside of the pipeline to be welded, thereby achieving a surrounding protection above the welding area. Manual welding operations can be performed along both sides. During welding, a suction pump draws the welding area along the filter collection section, suction pipe and suction port. The suction forcefully draws in and filters the tiny sputtered metal particles into the filter collection section, which not only ensures welding operation space on both sides, but also achieves the separation and collection of sputtered metal particles, avoiding high temperature burns from sputtering, and preventing sputtered metal particles from falling into the welding area and affecting the welding. The overall protection effect is good.

[0014] 2. This utility model utilizes the combined action of a clamping ring, a clamping mechanism, and a drive deflection component. During the welding process, the drive deflection component controls the rotation of the collar, thereby causing the two sets of clamped and fixed pipes to rotate synchronously. This achieves anti-spatter welding while continuously changing the welding position by automatically deflecting the pipes to be welded, completing the circumferential welding operation. No deflection operation is required from the welding worker, making welding simple, convenient, and highly efficient. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides an anti-splash device for welding aluminum alloy tubes, including a base 1 and a protective cover 8. A top frame 6 is fixedly installed on the top of the base 1. A lifting mechanism 7 is fixedly installed inside the top frame 6. The movable end of the lifting mechanism 7 is fixedly connected to the protective cover 8. The protective cover 8 is a ring with a notch. An observation window 9 is provided on the front of the outer side of the protective cover 8. An intake port 10 is provided on the back of the outer side of the protective cover 8. The top of the intake port 10 is connected to the intake pipe 11. The top of the intake pipe 11 is connected to the filter collection part 13. An intake pump 12 is connected above the filter collection part 13. The filter collection part 13 sucks in the splashed metal particles and collects them inside.

[0023] The lifting mechanism 7 controls the lifting and moving of the protective cover 8. The lifting mechanism 7 is an electric telescopic rod or a telescopic corrugated pipe. The former automatically controls the lifting position, while the latter allows for manual and convenient adjustment of the protective position.

[0024] The filter collection section 13 includes a collection frame 131, a filter frame 132, a partition plate 133, a through hole 134, and a sealing cover 135. The filter frame 132 is movably sleeved into the interior of the collection frame 131 along the end of the collection frame 131. The partition plate 133 is fixed inside the filter frame 132. A filter hole is provided on the right side of the top of the filter frame 132. The through hole 134 is opened on the left side of the bottom of the collection frame 131. The bottom of the partition plate 133 is provided with a connecting hole corresponding to the through hole 134. The sealing cover 135 is fixedly connected to the outer end of the filter frame 132.

[0025] By setting the suction position of the through hole 134 to be offset from the filter hole position at the top of the filter frame 132, and in combination with the separation function of the partition plate 133, a collection space is established on the one hand, and the metal particles sucked in are filtered and accumulated on the right side of the collection space of the filter frame 132, so as to prevent the metal particles sucked in from falling out again through the through hole 134. When the filter frame 132 is movably installed and slides outward, the metal particles stored and collected inside can also be separated and taken out from the collection frame 131. The inner wall of the sleeve interface on the left end of the collection frame 131 is provided with a sealing gasket to maintain the seal after the filter frame 132 is sleeved. The sealing cover 135 assists in covering and sealing. The sealing cover 135 is provided with a magnetic plate, which is attracted and fixed to the collection frame 131 by magnetic plate.

[0026] The base 1 has symmetrically distributed upright plates 2 fixed on its top. The upright plates 2 have a rotating pipe fixing mechanism inside, which fixes the aluminum alloy pipe to be welded. The pipe fixing mechanism includes a collar 3, a clamping ring 4, a clamping mechanism 5, and an adjusting component 15. The collar 3 is rotatably installed in the upright plate 2 through a bearing. The clamping mechanism 5 is fixed to the end of the collar 3 and is distributed at equal intervals around the inner wall of the clamping ring 4. The adjusting component 15 is connected to the outer side of the clamping ring 4. The clamping ring 4 has an annular cavity 14 inside. The clamping mechanism 5 includes a sleeve 51, a clamping rod 52, and a spring 53. The sleeve 51 is fixed to the inner wall of the clamping ring 4. The clamping rod 52 is movably sleeved in the sleeve 51. One end of the spring 53 is fixedly connected to the inner end of the clamping rod 52, and the other end of the spring 53 is fixed in the annular cavity 14.

[0027] By utilizing the movement of the clamping rod 52, it can be clamped and fixed along the outside of the inserted pipe, and can also adapt to pipes of different sizes. The outer side of the clamping rod 52 is provided with a sealing gasket located in the sleeve 51 to maintain dynamic sealing sliding and prevent air leakage.

[0028] The adjusting assembly 15 includes a fixed sleeve 151 and a piston part 152. The rod of the piston part 152 is threadedly sleeved on the end of the fixed sleeve 151, and the movable end of the piston part 152 is movably sleeved in the fixed sleeve 151. The fixed sleeve 151 communicates with the ring cavity 14 through a small hole on the outer side of the clamping ring 4.

[0029] The piston part 152, which is connected by a rotating thread, compresses the inside of the fixed sleeve 151, thereby increasing the internal pressure. The air pressure is used to push the clamping rod 52 to move, and the rotation of the thread can maintain the self-locking after rotation adjustment. A sealing ring is provided on the outer side of the inner end of the piston part 152 to maintain dynamic sealing movement.

[0030] The base 1 is equipped with a drive deflection assembly 16, which controls the rotation of the pipe fixing mechanism. The drive deflection assembly 16 includes a toothed plate 161, a connecting plate 162, an electric push rod 163, and a gear 164. The toothed plate 161 and the gear 164 are fixedly connected. The gear 164 is fixedly sleeved on the outside of the collar 3. The two toothed plates 161 are connected into a whole through the connecting plate 162. The movable end of the electric push rod 163 is fixedly connected to the connecting plate 162.

[0031] The drive deflection assembly 16 drives the collar 3 to rotate, thereby controlling the rotation of the clamped and fixed pipe to be welded. The toothed plate 161 drives the meshing gear 164 to rotate, thus completing the rotation control.

[0032] The working principle and usage process of this utility model are as follows: During welding, the pipe to be welded is sleeved inside the collar 3, and the gas in the connected annular cavity 14 is compressed by the rotation adjustment component 15, so that the clamping mechanism 5 clamps and fixes the pipe to be welded, and the two sets of pipes to be welded are sleeved and fixed, and the end areas to be welded are kept in contact. The lifting mechanism 7 is operated to move the protective cover 8 down and sleeve it on the outside of the pipe to be welded. Manual welding is performed along both sides, and the suction pump 12 is started during welding. The welding area is sucked through the filter collection part 13, the suction pipe 11 and the suction port 10. When metal particles are sputtered during welding, the suction forcefully sucks in the tiny sputtered metal particles and filters them in the filter collection part 13. As the welding process progresses, the drive deflection component 16 is started to control the collar 3 to rotate, thereby driving the two sets of clamped and fixed pipes to rotate synchronously, completing the circumferential welding.
