Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a steel structure welding workbench. Background Technology

[0002] Steel structure welding workbenches are essential equipment in industrial manufacturing used to support, position, and fix steel structure workpieces for efficient welding operations. In fields such as steel structure processing, construction, bridge building, shipbuilding, and heavy machinery manufacturing, the stability, precision, and durability of welding workbenches directly affect welding quality and production efficiency.

[0003] Patent CN222095201U discloses a welding platform for cylindrical tubular steel components, belonging to the field of steel component technology. It solves the problem that manual rotation of steel components is necessary for rotation, which is time-consuming and labor-intensive due to the large weight of the components. This welding platform for cylindrical tubular steel components includes a worktable with a support frame slidably connected to it. An electric telescopic rod is fixed to the support frame, and a welding head is fixed to the telescopic end of the electric telescopic rod. Mounting rings are rotatably connected to both ends of the worktable, and a driving mechanism is provided between the worktable and the mounting rings. A fixing mechanism is provided inside the mounting rings.

[0004] The aforementioned disclosed patents still have the following technical defects: there is only one welding station for fixing and welding pipes. When performing continuous welding work, it is necessary to wait for the previous batch of pipes to be processed before the next batch of pipes can be fixed, welded and unloaded. The waiting between each process makes the equipment inefficient. Utility Model Content

[0020] Example 1

[0021] like Figures 1-3As shown in the figure, the steel structure welding workbench proposed in this embodiment includes a frame 1, a rotary drive mechanism, two clamping devices and two arc plates 8.

[0022] A welding machine mounting bracket 4 is provided on the upper end of the frame 1; a mounting shaft 13 is rotatably mounted on the upper end of the frame 1, and a servo geared motor 2 for driving the mounting shaft 13 to rotate is mounted on the side of the frame 1.

[0023] Two clamping devices are symmetrically mounted on the mounting shaft 13. Each clamping device includes a first turntable 3 and multiple clamping mechanisms. The first turntable 3 is fixedly connected to the mounting shaft 13. The clamping devices have at least three clamping mechanisms, ensuring the device has at least three stations: feeding, welding, and unloading. Multiple clamping mechanisms on the same side are arranged in a circular array, and the clamping mechanisms on both sides correspond one-to-one. Each clamping mechanism includes a clamping disc 7, a plug 9, a second turntable 16, and an elastic connecting assembly. The clamping disc 7 and the corresponding... The first turntable 3 on the side is connected by an elastic connecting component, which includes a guide rod 14, a spring 15 and a pull ring 12. The guide rod 14 moves through the first turntable 3, and its two ends are connected to the clamping plate 7 and the pull ring 12 respectively. The spring 15 is sleeved on the guide rod 14. The second turntable 16 is rotatably mounted on the clamping plate 7. The plug 9 is mounted on the second turntable 16. The end of the plug 9 away from the second turntable 16 is provided with a chamfer. The chamfer makes it easy for the plug 9 to be inserted into the inside of the round tube.

[0024] The rotary drive mechanism includes an electric push rod 5, a rack 6, and multiple gear rings 17. The multiple gear rings 17 are respectively mounted on the second turntable 16 on the corresponding side. The electric push rod 5 is mounted on the welding machine mounting frame 4, and the rack 6 is connected to the output shaft of the electric push rod 5.

[0025] Two arc-shaped plates 8 are symmetrically arranged, and both arc-shaped plates 8 are connected to the lower part of the frame 1. The arc-shaped plates 8 are arranged at an angle.

[0026] In this embodiment, when welding two round tubes, one round tube is first coaxially positioned with the clamping disc 7, so that the plug 9 is inserted into the inside of the round tube to limit its movement. Then, the clamping disc 7 on the other side is pushed outward to coaxially position the other round tube with the clamping disc 7, and the plug 9 on the other side is inserted into the inside of the other round tube. Then, the clamping disc 7 is released, and the two round tubes are pressed together by the elastic force of the spring 15, thereby achieving the positioning and centering of the round tubes to facilitate subsequent welding.

[0027] To facilitate the fixing of the round tubes, a support frame is provided in the feeding area between the two first turntables 3. The support frame is used to support the two round tubes.

[0028] The servo reduction motor 2 is set to drive the two round tubes to move to the upper position. The welding machine is installed on the welding machine mounting frame 4. The welding machine can weld the two round tubes. During this process, the electric push rod 5 is driven to drive the rack 6 to move. The rack 6 can drive the gear ring 17 to rotate during the movement, thereby driving the second turntable 16 and the round tubes to rotate, thus realizing the rotation welding of the round tubes.

[0029] After the welding work is completed, the first turntable 3 is continuously driven to rotate. When the clamping plate 7 contacts the arc plate 8, the first turntable 3 is continuously driven to rotate. At this time, the first turntable 3 gradually moves away from the center of the frame 1 under the limiting action of the arc plate 8 until both end caps 9 are pulled out from the inside of the round tube, thereby releasing the limiting action of the round tube and realizing the function of automatic unloading.

[0030] Example 2

[0031] like Figure 2 As shown in the figure, the steel structure welding workbench proposed in this embodiment has an inclined plate 10 below the first turntable 3 compared to the first embodiment. The inclined plate 10 is connected to the frame 1. The frame 1 is provided with multiple airbags 11. The inclined plate 10 is used to transfer the unloaded pipe to the bottom position. The airbags 11 can play a buffering role.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
