Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle frame welding technology, specifically a spark prevention device for vehicle frame welding. Background Technology
[0002] Electric bicycles, as an environmentally friendly mode of transportation, are not only suitable for daily commuting and travel, but also prioritize environmental protection in their manufacturing process. During the production of these bicycle frames, to enhance the strength of the main beam, bent tube reinforcing plates and angled support reinforcing plates are typically welded onto it. Furthermore, seat mounts and shock absorber mounting bolts are welded to the ends of the main beam to ensure the frame's stability and durability.
[0003] However, under current technological conditions, welding electric bicycle frames may generate a large amount of high-temperature welding slag. If appropriate protective measures are not taken, this slag may cause injury to workers. At the same time, the slag scattered on the welding table and the surrounding ground increases the workload of workers in cleaning, thereby indirectly increasing the labor intensity.
[0004] Therefore, this utility model provides a spark prevention device for vehicle frame welding. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A spark-preventing device for vehicle frame welding, comprising a workbench; a placement platform is installed in the middle of the workbench; multiple pillars are fixedly connected to the top of the workbench; a top plate is fixedly connected to the top of each pillar; a cylinder is fixedly connected to the middle of the top plate; a welding gun is fixedly connected to the bottom of the cylinder; dust suction ports are fixedly connected to both sides of the workbench; a dust suction pipe is connected to one side of each dust suction port; a fan is connected to the middle of the dust suction pipe; a dust collection box is connected to one end of the dust suction pipe; the dust collection box is fixedly connected to the workbench; and the fan is fixedly connected to the dust collection box. During operation, the vehicle frame is first placed on the placement platform. Installation is performed, followed by starting the cylinder. The cylinder controls the welding gun to reach the position on the frame where welding is required, and welding is carried out on the frame. During this process, the fan starts, generating suction in the suction pipe and suction port to draw in the sparks and debris generated during welding. The debris is then transported through the suction pipe into the dust collection box, where it accumulates. Once the dust collection box is full, the debris and impurities are collected and disposed of. By using a fan to generate suction, sparks and debris generated during welding are collected in the suction port, then through the suction pipe and into the dust collection box for subsequent centralized disposal, reducing the workload of workers and ensuring their safety.
[0007] Preferably, the welding gun has an air guide plate on one side, which is fixedly connected to the workbench. An external air pipe is connected to one side of the air guide plate, and multiple air holes are connected to the other side. These air holes are angled. During operation, the external air pipe connects to an air pump, transmitting airflow into the air guide plate. The airflow finally exits through the air holes, which correspond to the workbench. This guides the sparks and debris generated during welding of the frame, causing them to fall downwards, facilitating collection by the dust extraction port. Simultaneously, it cools the welded area of the frame, reducing the risk of burns to workers. By introducing airflow through the external air pipe and allowing the airflow from the air holes to act on the frame, the air holes and the dust extraction port work together to form an airflow channel, guiding more sparks and debris into the dust extraction port for collection. This further enhances the efficiency of spark collection and reduces the workload of workers.
[0008] Preferably, the outer side of the placement platform is provided with a mesh plate, which is fixedly connected to the workbench and communicates with the dust collection box. During operation, the mesh plate and the dust collection box are connected, so that sparks and debris splashed during welding can pass directly through the mesh plate and fall into the dust collection box. Debris that splashes too far is more easily collected by the suction port and eventually enters the dust collection box.
[0009] Preferably, the bottom of the mesh plate is provided with two guide plates, which are fixedly connected to the dust collection box. The guide plates are inclined so that when working, sparks and debris fall into the dust collection box and are concentrated in the middle of the dust collection box under the guidance of the guide plates, reducing the phenomenon of debris accumulation at both ends of the dust collection box causing the end of the suction pipe to be blocked.
[0010] Preferably, the bottom of the guide plate is provided with multiple sponge pads, which are fixedly connected to the bottom of the dust collection box. During operation, the sponge pads are soaked in water to extinguish and cool the sparks, so as to prevent the dust collection box from being damaged by the heat, and at the same time reduce the occurrence of sparks reigniting.
[0011] Preferably, the support column is provided with multiple baffles on its outer side. The baffles are fixedly connected to the worktable. During operation, the baffles surround the worktable on the outside to reduce the occurrence of sparks and debris flying over the worktable and scattering outside the worktable.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The vehicle frame welding spark prevention device of this utility model uses a fan to generate suction to collect sparks and debris generated during welding into the suction port. After passing through the suction pipe, the debris is collected into the dust collection box for subsequent centralized processing, reducing the workload of workers and ensuring their safety.
[0014] 2. The spark protection device for vehicle frame welding described in this utility model introduces airflow through an external air pipe, and the airflow emitted from the air hole acts on the vehicle frame. The air hole and the dust suction port work together to form an airflow channel, guiding more spark debris into the dust suction port for collection, further enhancing the collection efficiency of sparks and reducing the workload of the staff.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figures 1 to 4As shown in the embodiment of this utility model, a spark protection device for vehicle frame welding includes a workbench 1; a placement platform 101 is installed in the middle of the workbench 1; multiple support columns 11 are fixedly connected to the top of the workbench 1; a top plate 12 is fixedly connected to the top of the support columns 11; a cylinder 13 is fixedly connected to the middle of the top plate 12; a welding gun 14 is fixedly connected to the bottom of the cylinder 13; dust suction ports 15 are fixedly connected to both sides of the workbench 1; a dust suction pipe 16 is connected to one side of the dust suction port 15; a fan 17 is connected to the middle of the dust suction pipe 16; a dust collection box 18 is connected to one end of the dust suction pipe 16; the dust collection box 18 is fixedly connected to the workbench 1; and the fan 17 is fixedly connected to the dust collection box 18. During operation, the vehicle frame is first placed on the placement platform 101 for installation. Then, cylinder 13 is activated, which controls the welding gun 14 to reach the position on the frame that needs to be welded, and welding is performed on the frame. During this process, fan 17 is activated, and fan 17 generates suction in the suction pipe 16 and suction port 15, which sucks in the sparks and debris generated during welding into the suction port 15. Then, under the transmission of the suction pipe 16, they enter the dust collection box 18 and finally accumulate in the dust collection box 18. After the dust collection box 18 is full, the debris and impurities in the dust collection box 18 can be collected and processed. By setting the fan 17 to generate suction, the sparks and debris generated by the welding gun 14 during welding are collected into the suction port 15, and after passing through the suction pipe 16, they are collected into the dust collection box 18 for subsequent centralized processing, reducing the workload of the staff and ensuring the safety of the staff.
[0024] like Figures 1 to 5 As shown, the welding gun 14 is provided with an air guide plate 2 on one side, which is fixedly connected to the workbench 1. An external air pipe 21 is connected to one side of the air guide plate 2, and multiple air holes 22 are connected to the other side of the air guide plate 2. The air holes 22 are set at an angle. During operation, the external air pipe 21 is connected to an air pump to transmit airflow into the air guide plate 2. The airflow finally dissipates from the air holes 22. The air holes 22 correspond to the placement platform 101 to guide the sparks and debris generated when the welding gun 14 welds the frame, causing them to fall to a lower position, which is more conducive to the full collection of the sparks and debris by the suction port 15. At the same time, it cools down the welding area of the frame and reduces the possibility of burns to the workers. By setting the external air pipe 21 to introduce airflow, the airflow dissipated from the air holes 22 acts on the frame. The air holes 22 and the suction port 15 work together to form an airflow channel, guiding more sparks and debris into the suction port 15 for collection, further enhancing the collection efficiency of sparks and debris and reducing the workload of the workers.
[0025] like Figures 1 to 3As shown, a mesh plate 3 is provided on the outer side of the placement platform 101. The mesh plate 3 is fixedly connected to the workbench 1 and is connected to the dust collection box 18. During operation, the mesh plate 3 and the dust collection box 18 are connected. Sparks and debris that fly during welding can pass directly through the mesh plate 3 and fall into the dust collection box 18. Debris that fly too far is more easily collected by the suction port 15 and eventually enters the dust collection box 18.
[0026] like Figure 3 As shown, the bottom of the mesh plate 3 is provided with two guide plates 4. The guide plates 4 are fixedly connected to the dust collection box 18. The guide plates 4 are inclined. During operation, sparks and debris fall into the dust collection box 18. Under the guidance of the guide plates 4, they are concentrated in the middle of the dust collection box 18, reducing the phenomenon that the end of the suction pipe 16 is blocked due to the accumulation of debris at both ends of the dust collection box 18.
[0027] like Figure 3 As shown, the bottom of the guide plate 4 is provided with multiple sponge pads 5, which are fixedly connected to the bottom of the dust collection box 18. During operation, the sponge pads 5 are soaked in water to extinguish and cool the sparks, so as to prevent the dust collection box 18 from being burned and to reduce the occurrence of sparks reigniting.
[0028] like Figures 1 to 2 As shown, the support column 11 is provided with multiple baffles 6 on its outer side. The baffles 6 are fixedly connected to the worktable 1. During operation, the baffles 6 surround the worktable 1 on the outside to reduce the phenomenon of sparks and debris flying over the worktable 1 and scattering outside the worktable 1.
[0029] Working principle: First, the frame is placed on the mounting platform 101 for installation. Then, cylinder 13 is activated, which controls the welding gun 14 to reach the position on the frame that needs welding. During this process, fan 17 is activated, generating suction in the suction pipe 16 and suction port 15. This suction draws in sparks and debris generated during welding into the suction port 15, and then, under the transmission of the suction pipe 16, into the dust collection box 18. Finally, the debris and impurities in the dust collection box 18 are collected and processed after the dust collection box 18 is full. Yes, by setting up the fan 17 to generate suction, the sparks and debris generated during welding by the welding gun 14 are collected into the dust collection port 15. After passing through the dust collection pipe 16, they are collected into the dust collection box 18 for subsequent centralized processing, reducing the workload of the workers and ensuring their safety. The external air pipe 21 is connected to the air pump, which transmits airflow into the air guide plate 2. The airflow finally exits from the air hole 22, which corresponds to the placement platform 101, guiding the sparks and debris generated by the welding gun 14 when welding the frame, causing them to fall downwards, which is more conducive to the dust collection port 15. It effectively collects sparks and cools the welded areas of the frame, reducing the risk of burns to workers. An external air pipe 21 guides airflow, while air vents 22 distribute the airflow onto the frame. The air vents 22 and the suction port 15 work together to form an airflow channel, guiding more sparks and debris into the suction port 15 for collection, further enhancing the efficiency of spark collection and reducing the workload of workers. The mesh plate 3 and the dust collection box 18 are connected, allowing sparks and debris from welding to pass directly through the mesh plate 3 and fall into the dust collection box 18, while those that fly too far... The debris is more easily collected by the suction port 15 and eventually enters the dust collection box 18. The sparks and debris fall into the dust collection box 18 and, guided by the guide plate 4, are concentrated in the middle of the dust collection box 18, reducing the phenomenon that the end of the suction pipe 16 will be blocked due to the accumulation of debris at both ends of the dust collection box 18. The sponge pad 5 is soaked in water to extinguish and cool the sparks to prevent them from being burned by the dust collection box 18 and to reduce the phenomenon of sparks reigniting. The baffle 6 surrounds the workbench 1 on the outside to reduce the phenomenon that the sparks and debris splashed across the workbench 1 and fall outside the workbench 1.
