Description

Technical Field

[0001] This utility model relates to the field of filter tank welding technology, and more specifically to a plasma cutting torch positioning welding device. Background Technology

[0002] A sediment filter tank is a device used in water treatment to remove suspended particulate matter and sediment from water. It typically consists of a container or tank. Using a sediment filter tank can effectively purify water sources and improve water quality. It is widely used in domestic, commercial, and industrial water treatment, swimming pools, and agricultural irrigation.

[0003] Due to the project's need to modify the filter tank, it is necessary to increase the height of the filter tank based on its original dimensions. In existing technology, manual welding by workers is usually used for processing. However, manual welding by workers is easily affected by external environmental interference, which can cause positioning deviations. As a result, it is difficult to ensure the perpendicularity and horizontality of the flange and the central axis of the tank after welding, thus affecting the quality of the filter tank welding process.

[0022] Please see Figures 1-2As shown, this utility model provides a plasma cutting torch positioning and welding device, including a frame 1, a rotating shaft 2 rotatably mounted on the top of the frame 1, a disc 3 fixedly mounted on the top of the rotating shaft 2, a filter tank 4 mounted on the disc 3, a welding tank 5 mounted on the filter tank 4, the welding tank 5 being adapted to the filter tank 4 and used for welding onto the filter tank 4, a flange 11 fixedly mounted on the bottom of the filter tank 4, and multiple positioning posts 12 fixedly mounted on the circumference of the disc 3, with multiple circular holes for the positioning posts 12 to pass through on the flange 11. The filter tank 4 is placed on the disc 3, and by having the multiple positioning posts 12 pass through the circular holes on the flange 11, the filter tank 4 is restricted, facilitating the rotation of the filter tank 4 by the disc 3. A drive mechanism is provided at the bottom of the frame 1. The drive assembly for rotating the shaft 2 includes a servo motor 8 and a reducer 9. The reducer 9 is fixedly mounted at the bottom of the frame 1, and its output end is fixed to the shaft 2. The servo motor 8 is fixedly mounted on one side of the reducer 9, and its output end is connected to the shaft 2 via the reducer 9. The servo motor 8 drives the shaft 2 to rotate via the reducer 9, which in turn drives the disc 3 to rotate. The disc 3 drives the filter tank 4 and the welding tank 5 to rotate synchronously, facilitating welding of the filter tank 4 and the welding tank 5. The reducer 9 is used to reduce the speed of the input shaft and increase the torque of the output shaft. A bearing 10 is located at the center of the frame 1, and the shaft 2 is rotatably connected to the frame 1 via the bearing 10, which ensures stable rotation of the shaft 2.

[0023] Please see Figure 1 and Figure 3 As shown, the side wall of the disc 3 is provided with a clamping mechanism 6 for fixing the welding tank 5. Two sets of clamping mechanisms 6 are provided, each including an L-shaped plate 61. The L-shaped plate 61 is fixedly mounted on the side wall of the disc 3.

The surface of the clamping plate 63 has an arc-shaped groove adapted to the outer wall of the welding tank 5. Rotating the rotating wheel 64 drives the screw 62... The screw 62 rotates, causing the clamping plate 63 to move closer to the welding tank 5. The welding tank 5 is clamped by the two clamping plates 63, preventing the welding tank 5 from shifting during rotation and welding. A limit rod 65 is fixedly installed on the outer wall of the clamping plate 63, and a limit plate 66 is fixedly installed on the side wall of the L-shaped plate 61. A circular hole is opened on the limit plate 66 for the limit rod 65 to slide through. The clamping plate 63 is limited by the cooperation between the limit rod 65 and the circular hole on the limit plate 66, so that the clamping plate 63 will not rotate with the screw 62.

[0024] Please see Figure 1 and Figure 4As shown, a welding mechanism 7 is provided on the frame 1. The welding mechanism 7 includes an electric push rod 71, which is fixedly mounted on the frame 1.

The plasma cutting torch body 74 is fixedly connected to the mounting plate 72. A support shaft 75 is fixedly mounted on the output end of the electric push rod 71 and is rotatably connected to the mounting plate 72. The mounting plate 72 has an inner cavity for the support shaft 75 to pass through. The support shaft 75 extends into the inner cavity and is fixedly fitted with a torsion spring 76. The mounting plate 72 is moved up or down by the electric push rod 71, which in turn moves the plasma cutting torch body 74 up or down to adjust the height of the plasma cutting torch body 74. The elastic force of the torsion spring 76 drives the mounting plate 72 to rotate. The mounting plate 72 drives the positioning wheel 73 to abut against the welding tank 5, thereby maintaining a fixed distance between the mounting plate 72 and the welding tank 5, which facilitates the plasma cutting torch body 74 to weld the filter tank 4 and the welding tank 5.

[0025] The specific working principle of this utility model is as follows: The filter tank 4 is placed on the disc 3, and then the welding tank 5 is placed on the filter tank 4. The rotating wheel 64 drives the screw 62 to rotate, which in turn drives the clamping plate 63 to move closer to the welding tank 5. The welding tank 5 is clamped by the two clamping plates 63, so that the welding tank 5 will not shift during rotation and welding. The servo motor 8 drives the rotating shaft 2 to rotate through the reducer 9. The rotating shaft 2 drives the disc 3 to rotate. The disc 3 drives the filter tank 4 and the welding tank 5 to rotate synchronously. The elastic force of the torsion spring 76 drives the mounting plate 72 to rotate. The mounting plate 72 drives the positioning wheel 73 to abut against the welding tank 5, thereby maintaining a fixed distance between the mounting plate 72 and the welding tank 5.
