Description

Technical Field

[0001] This utility model relates to the field of welding positioning technology, specifically to a welding positioning fixture for an arc-shaped pipe frame used in cover production. Background Technology

[0002] The arc-shaped pipe support is made by connecting and welding multiple arc-shaped short pipes together. During the welding process, a positioning device is needed to assist in the placement of the arc-shaped short pipes and to avoid uneven connection of the arc-shaped short pipes, which would result in an unsatisfactory arc shape of the welded arc-shaped pipe support.

[0003] Welding of curved pipe supports produces welding fumes on their surface, which can affect the welders' vision and respiratory health. In addition, the surface temperature of the curved pipe supports is high after welding, and for safety reasons, it needs to be cooled before it can be moved. The current welding positioning device has a fixed internal fume extraction structure, and the fume extraction effect needs to be improved. Moreover, it can only extract fumes and does not have the function of cooling the curved pipe supports after welding, so its functionality is generally limited. Utility Model Content

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.

[0018] Please see Figure 1-3 The present invention provides a welding and positioning fixture for an arc-shaped tube frame used in the production of a cover, comprising: a base plate 1 and support plates 2 installed at both ends of the top outer wall of the base plate 1; a positioning frame 3 installed on one side outer wall of the two support plates 2; an arc-shaped plate 4 installed on one side outer wall of the two support plates 2; a slot 5 opened on the top outer wall of the arc-shaped plate 4; a rack 6 fixed on one side inner wall of the arc-shaped plate 4; a moving component 7 slidably connected to the inner wall of the slot 5; a driving component 8 installed at one end of the top outer wall of the moving component 7; an airflow component 9 installed at the other end of the top outer wall of the moving component 7; a fixing plate 10 installed on the top outer wall of the base plate 1; and an exhaust pipe 11 installed on the top of the fixing plate 10.

[0019] It should be noted that the curved short pipes can be placed on the positioning frame 3, so that the curved short pipes are connected to the inner wall of the positioning frame 3. When welding the curved short pipes, the airflow component 9 can be used to extract and exhaust smoke above the positioning frame 3, and the smoke is drawn into the exhaust pipe 11 and discharged to avoid the smoke affecting the workers' vision and respiratory health. The set drive component 8 can drive the moving component 7 to move along the arc of the curved plate 4, thereby moving the moving component 7 to facilitate moving the airflow component 9 above the welding point. The position of the airflow component 9 can be adjusted according to the change of the welding position, which helps to improve the smoke extraction effect. After the curved short pipes are welded together, the airflow component 9 can blow air downwards in the opposite direction, blowing the airflow onto the surface of the curved pipe frame for air cooling and heat dissipation, realizing integrated smoke extraction and cooling, and improving the functionality of the device.

[0020] In a preferred embodiment, the moving component 7 includes a slider 701 and a T-shaped plate 702 mounted on the top outer wall of the slider 701.

[0021] It should be noted that the slider 701 can slide on the inner wall of the slot 5, thereby driving the T-shaped plate 702 to move.

[0022] In a preferred embodiment, the drive assembly 8 includes a motor 801 and a gear 802 mounted on the bottom of the output shaft of the motor 801.

[0023] It should be noted here that motor 801 can drive gear 802 to rotate.

[0024] In a preferred embodiment, the airflow assembly 9 includes a fixed cover 901, a fan 902 rotatably mounted on the inner wall of the fixed cover 901, an electric rotary table 903 mounted on the outer wall of one side of the fixed cover 901, and a conductive slip ring 904 mounted on one end of the support rod of the fan 902.

[0025] It should be noted that: the fan 902 blows air upwards to extract fumes during welding, and blows air downwards to cool the welded arc-shaped pipe frame. The electric rotary table 903 can drive the fan 902 to rotate, and adjust the air blowing direction of the fan 902.

[0026] In a preferred embodiment, the top end of the fixed cover 901 is rotatably connected to the inner wall of the bottom opening of the exhaust pipe 11.

[0027] It should be noted that when the fixed cover 901 moves in an arc, it does not affect the connection of the exhaust pipe 11.

[0028] In a preferred embodiment, the rack 6 has an arc-shaped structure, and the gear 802 meshes with the rack 6.

[0029] It should be noted that the rotation of gear 802 can apply force to rack 6, pushing slider 701 to slide on the inner wall of slot 5.

[0030] Working principle: The curved short pipes can be placed on the positioning frame 3, so that the curved short pipes are connected to the inner wall of the positioning frame 3. When welding the curved short pipes, the electric fan 902 blows air upward to extract the smoke, which is then sent into the exhaust pipe 11 to be discharged, avoiding the smoke from affecting the workers' vision and respiratory health. The motor 801 drives the gear 802 to rotate, and the rotation of the gear 802 applies force to the rack 6, pushing the slider 701 to slide on the inner wall of the slot 5, thereby driving the electric fan 902 to move along the arc of the curved plate 4, making it easy to move the electric fan 902 above the welding point. The position of the electric fan 902 can be adjusted according to the welding position, which helps to improve the smoke extraction effect. After the curved short pipes are welded together, the electric rotary table 903 can drive the electric fan 902 to rotate, so that the electric fan 902 blows air downward, blowing the airflow onto the surface of the curved pipe frame for air cooling and heat dissipation, realizing integrated smoke extraction and cooling, and improving the functionality of the device.
