Technical Field

[0001] This application relates to the field of welded pipe processing technology, specifically a welded pipe processing positioning mechanism. Background Technology

[0002] Welded pipe, also known as welded steel pipe, is a steel pipe made by rolling steel plates or strips into shape and then welding them. With the rapid development of high-quality strip steel continuous rolling production and the advancement of welding and inspection technologies, the variety and specifications of welded steel pipes are increasing day by day. Welded pipes have the advantages of low cost and high production efficiency. During the processing of welded pipes, they often need to be clamped.

[0003] Currently, existing positioning devices cannot clamp welded pipes of different specifications, cannot meet the needs under different conditions, and have certain limitations and poor applicability. Utility Model Content

[0005] This application provides a welding pipe processing positioning mechanism, including a base plate. Two movable plates are symmetrically slidably connected to the upper end of the base plate. A connecting rod is connected to the side wall of each of the two movable plates facing each other. A clamping plate is connected to the other end of each connecting rod. A motor is installed on the upper end of the base plate. The output end of the motor is connected to a double-acting screw through a coupling. The double-acting screw is threadedly connected to the two movable plates. A lower support plate is provided above the base plate. The lower support plate is slidably connected to the corresponding movable plate. A lifting assembly for driving the lower support plate to move vertically is installed on the movable plate. A mounting frame is connected to the rod wall of the connecting rod. A rotating shaft is rotatably connected to one side wall of the mounting frame. An upper support plate is fixedly sleeved on the rotating shaft. A rotating assembly for driving the rotating shaft to rotate is installed on the mounting frame.

[0006] By adopting the above technical solution, during use, the welded pipe to be processed is placed between two clamping plates. The motor is started, and its operation drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw applies force to the moving plate through the threaded action. The moving plate, subjected to this force, moves horizontally towards each other. This movement of the moving plate, through the connecting rod, drives the clamping plates to move, thus clamping and fixing the welded pipe. Then, the lifting assembly moves the lower support plate upwards, causing it to contact the bottom of the welded pipe. Next, the rotating assembly drives the upper support plate to rotate, causing it to contact the top of the welded pipe. At this point, the welded pipe is positioned. This structure allows for the positioning of welded pipes of different sizes to meet the needs of different conditions, thereby improving the applicability of the device.

[0008] By adopting the above technical solution, the cylinder is started, which drives the movable block to move vertically, and the movement of the movable block drives the lower support plate to move.

[0009] Optionally, a guide rod is fixedly connected to the sliding hole sidewall of the corresponding movable plate. The guide rod passes through the movable block, and the movable block is slidably connected to the guide rod.

[0010] By adopting the above technical solution, the moving block is limited, thereby improving the stability of the moving block's movement.

[0011] Optionally, the rotating assembly includes a motor fixedly mounted on a mounting bracket, and the output end of the motor is connected to the rotating shaft via a coupling.

[0012] By adopting the above technical solution, when the motor is started, the motor will drive the rotating shaft to rotate.

[0013] Optionally, two symmetrical grooves are formed on the upper end of the base plate, and two sliders are symmetrically slidably connected to the inner wall of the grooves, with the upper ends of the sliders connected to the corresponding movable plates.

[0014] By adopting the above technical solution, the moving plate is limited to prevent it from rotating.

[0015] Optionally, a slide rod is fixedly connected to the inner wall of the chute, the slide rod passes through the slider, and the slider is slidably connected to the slide rod.

[0016] By adopting the above technical solution, the slider is prevented from detaching from the groove.

[0017] Optionally, the lower end of the slider is provided with a rolling groove, and a rolling ball is provided in the rolling groove. The rolling ball passes through the opening of the rolling groove and is tumbling and connected to the bottom of the groove.

[0018] By adopting the above technical solution, the friction between the slider and the groove is reduced.

[0019] Optionally, anti-slip pads are installed on the sidewalls of both clamps facing each other.

[0020] By adopting the above technical solution, the friction of the clamping plate is improved.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

The rotation of the bidirectional lead screw 6 will apply a force to the moving plate 2 through the thread action. The moving plate 2 will move horizontally towards each other due to the force. The movement of the moving plate 2 will drive the clamping plates 4 to move through the connecting rod 3. The two clamping plates 4 will clamp and fix the welded pipe.

Then, the rotating component will drive the rotating shaft to rotate so that the upper support plate 9 abuts against the top of the welded pipe. At this time, the welded pipe will be positioned. The above structure can position welded pipes of different sizes to meet the needs under different conditions, thereby improving the applicability of the device.

Then, the cylinder 10 will move the lower support plate 7 upward so that the lower support plate 7 abuts against the bottom of the welded pipe. Then, the motor 13 will drive the rotating shaft to rotate the upper support plate 9 so that the upper support plate 9 abuts against the top of the welded pipe. At this time, the welded pipe will be positioned.
