DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-6 A metal pipe clamping device suitable for various shapes includes a clamp body 1, a displacement mechanism 2 located at the upper end of the clamp body 1, and a clamping mechanism 3 located at the upper end of the displacement mechanism 2. A driving groove 11 is provided in the middle position of the upper end surface of the clamp body 1, and guide grooves 13 are provided on both sides of the upper end surface of the clamp body 1. A DC motor 12 is installed on the side surface of the clamp body 1, and a base 21 is fixedly connected to the lower end surface of the displacement mechanism 2. A guide block 211 is provided at the lower end of the base 21. A limiting groove 31 is provided on the side surface of the clamping mechanism 3. A rotating shaft 32 is rotatably connected to the inner side surface of the clamping mechanism 3, and a mounting column 33 is fixedly connected to the outer surface of the rotating shaft 32. A clamping rod 34 is fixedly connected to the upper end surface of the mounting column 33. The clamping rod 34 is set in a conical shape. The outer surface of the rod 34 is covered with a bent tube element 4 and a straight tube element 5. When in use, one end of the tube can be covered on the outer surface of the clamping rod 34 according to the shape of the metal tube. The clamping rod 34 is specifically made of a rubber material with a certain elasticity. Through the conical and elastic clamping rod 34, metal tubes of various apertures can be covered. Then, the DC motor 12 is driven to rotate forward according to the length of the metal tube, and the displacement mechanism 2 and the clamping mechanism 3 are driven to move in opposite directions through the rotation of the bidirectional screw 111 through the moving block 112, so that the spacing between the two clamping mechanisms 3 is adapted to the length of the metal tube. After adaptation, the staff can rotate the rotating shaft 32 according to the shape of the tube to adjust the angle of the clamping rod 34, so that the other end of the metal tube is covered on the outer surface of the clamping rod 34. The bent tube element 4 is covered as shown in FIG. Figure 2 As shown, the straight tube element 5 is set as Figure 3 As shown, the clamping rod 34 with adjustable angle can be adapted to various shapes of metal pipes to a certain extent. After the two ends of the metal pipe are fitted, the DC motor 12 can be driven to reverse again to move the two clamping mechanisms 3 in opposite directions. At this time, the two clamping rods 34 generate pressure to tighten the metal pipe, thereby enriching the overall function and increasing the overall applicability.

[0021] Furthermore, a bidirectional screw 111 and a moving block 112 are provided inside the driving groove 11, and the output end of the DC motor 12 penetrates into the driving groove 11 and is transmission-connected to the bidirectional screw 111, and the outer surface of the bidirectional screw 111 is threadedly connected with the moving block 112. When in use, by setting the DC motor 12 and the bidirectional screw 111, the DC motor 12 can drive the bidirectional screw 111 to rotate forward or reverse. When the bidirectional screw 111 rotates forward, the two moving blocks 112 move in opposite directions, and when the bidirectional screw 111 reverses, the two moving blocks 112 move in opposite directions.

[0022] Furthermore, the upper surface of the moving block 112 is fixedly connected to the lower surface of the base 21, the guide block 211 and the base 21 are set as an integrally formed structure, and the guide block 211 is slidably connected to the guide groove 13. When in use, by setting the guide block 211 and the guide groove 13, the displacement mechanism 2 can drive the clamping mechanism 3 to move more stably.

[0023] Furthermore, the lower end of the clamping mechanism 3 is fixedly connected to the upper surface of the displacement mechanism 2, and the two sides of the mounting column 33 are fixedly connected with the limiting rod 331, and the limiting rod 331 is slidably connected to the limiting groove 31. When in use, by setting the limiting rod 331 and the limiting groove 31, the mounting column 33 can drive the clamping rod 34 to rotate in a circle more stably, and at the same time provide a limiting effect.

[0024] Working principle: The utility model is a metal pipe clamping device suitable for various shapes. The clamping rod 34 made of rubber material has a certain elasticity and is set to a cone. Such a design allows the clamping rod 34 to be fitted on metal pipes of various apertures. When in use, firstly, one end of the metal pipe is fitted on the outer surface of the clamping rod 34, and then the DC motor 12 is driven to rotate forward, and the displacement mechanism 2 and the clamping mechanism 3 are driven to move in opposite directions through the bidirectional screw 111 and the moving block 112, so that the spacing between the two clamping mechanisms 3 is adapted to the length of the metal pipe. Then, the staff can rotate the rotating shaft 32 according to the shape of the pipe to adjust the angle of the clamping rod 34, so that the other end of the metal pipe can be smoothly fitted on the outer surface of the clamping rod 34. Therefore, it can be applicable to metal pipes of various shapes to a certain extent. When the two ends of the metal pipe are installed, the DC motor 12 is driven to reverse again to make the two clamping mechanisms 3 move back to back. At this time, the two clamping rods 34 generate pulling force to tighten the metal pipe to ensure that the pipe will not move during the processing, thereby completing the subsequent processing operations. Through the sliding connection between the guide block 211 and the guide groove 13, the displacement mechanism 2 can be made more stable when driving the clamping mechanism 3 to move, ensuring the accurate alignment of the clamping mechanism 3 and the metal pipe. The sliding connection between the limit rod 331 and the limit groove 31 provides a stable limiting effect for the mounting column 33 when driving the clamping rod 34 to rotate in a circle, thereby enriching the overall function and increasing the overall applicability.
