Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe processing clamping, and particularly relates to a clamping mechanism for steel pipe processing. Background Technique

[0002] Steel pipes are not only used for transporting fluids and powdery solids, exchanging heat energy, manufacturing mechanical parts and containers, but also an economical steel material; and the size requirements for steel pipes vary. At this time, further processing is required. To ensure the stability during the processing, it is natural to be equipped with a corresponding clamping structure to clamp and fix the steel pipe. After the existing clamping equipment fixes the steel pipe, after processing the steel pipe for a period of time, it is necessary to process the concealed positions and blocked positions of the steel pipe. At this time, it is necessary to loosen the clamping and manually rotate and move the pipe. For small steel pipes, manual adjustment can be carried out, but for relatively thick and large steel pipes, manual adjustment cannot be carried out conveniently and effectively. Therefore, in view of the above problems, improvement is needed now. Content of the Utility Model

Detailed implementation manner

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] Given by Figures 1 to 4 The present invention includes an inverted H-shaped pedestal 1. Long grooves 2 are provided on both sides of the top of the inverted H-shaped pedestal 1. Two first rollers 3 are rotatably connected inside the two long grooves 2. A pair of movable and adjustable inverted L-shaped sliders 4 are symmetrically provided at both ends of the top of the inverted H-shaped pedestal 1. A pair of rotatable and adjustable clamping pressing plates 5 are symmetrically connected to both ends of the top of the inverted H-shaped pedestal 1. The two clamping pressing plates 5 on the same side of the top of the inverted H-shaped pedestal 1 are arranged in a staggered manner. Rubber pads 6 for clamping the steel pipe are fixedly installed on one side of the four clamping pressing plates 5. Fixing blocks 7 are fixedly installed in the middle of the other side of the four clamping pressing plates 5. One ends of the four fixing blocks 7 are respectively rotatably connected to the tops of the four inverted L-shaped sliders 4 by adjusting rods 8. The steel pipe is located between the four first rollers 3 and the four rubber pads 6. By pushing the four clamping pressing plates 5 to rotate through the four adjusting rods 8 through the four fixing blocks 7, the rubber pads 6 are driven to clamp the steel pipe, so that the steel pipe is stably and firmly clamped between the surfaces of the four first rollers 3.

[0016] In the middle of the top of the inverted H-shaped pedestal 1, an installation groove 9 is provided. Inside the installation groove 9, a liftable and adjustable U-shaped plate 10 is installed. Inside the U-shaped plate 10, second rollers 11 are rotatably installed at equal intervals. In the middle of the bottom of the inverted H-shaped pedestal 1, a second installation groove 16 is provided. Four through holes 17 are provided between the top of the second installation groove 16 and the installation groove 9. Inside the four through holes 17, lift rods 18 are movably inserted. The tops of the four lift rods 18 are fixedly connected to the bottom of the U-shaped plate 10. Between the lower parts of two adjacent lift rods 18 inside the second installation groove 16, a fixing plate 20 is fixedly connected. Horizontal transverse grooves 21 are provided in the middle of the two fixing plates 20. Inside the second installation groove 16, a second double-output shaft motor 22 is installed. At both ends of the second double-output shaft motor 22, discs 23 are fixedly connected. At the edges of the two discs 23, toggle pins 24 are fixedly connected. The two toggle pins 24 are respectively located inside the two horizontal transverse grooves 21, so as to effectively adjust the lifting of the U-shaped plate 10;

[0017] When it is necessary to move and adjust the steel pipe, separate the four clamping pressing plates 5 from the steel pipe, and then start the second double-output shaft motor 22 to rotate the two discs 23 by 90° to drive the two toggle pins 24 to rotate. The rotation of the two toggle pins 24 will drive the two fixing plates 20 to move up and down through the horizontal transverse grooves 21. The upward movement of the two fixing plates 20 will push the lift rods 18 to move up, so that the four lift rods 18 push the U-shaped plate 10 to move up. The upward movement of the U-shaped plate 10 will push the steel pipe on the surface of the four first rollers 3 through the second rollers 11, so that the steel pipe is separated from the first rollers 3. Then, the steel pipe can be horizontally moved by the rolling of the second rollers 11; after the movement is completed, lower the U-shaped plate 10 so that the steel pipe is inserted into the interior between the four first rollers 3 again.

[0018] At both ends of the top of the inverted H-shaped pedestal 1, a pair of vertical sliding grooves 12 are provided. At the lower parts of the vertical sliding grooves 12, threaded shafts 13 are rotatably connected. The inverted L-shaped sliders 4 are installed inside the vertical sliding grooves 12 and are threadedly connected to the bidirectional threaded shafts 13. The threaded shafts 13 inside each pair of vertical sliding grooves 12 are symmetrically arranged, so that the two inverted L-shaped sliders 4 on the same side of the top of the inverted H-shaped pedestal 1 can move synchronously relative to or away from each other. On both sides of the bottom of the inverted H-shaped pedestal 1, first installation grooves 14 are provided. At the tops of the first installation grooves 14, first double-output shaft motors 15 are installed. The opposite ends of the two threaded shafts 13 on the same side of the top of the inverted H-shaped pedestal 1 respectively extend into the interior of the first installation grooves 14 and are fixedly connected to both ends of the first double-output shaft motors 15, so as to effectively adjust the clamping pressing plates 5;

[0019] The steel pipe is placed between the four first rollers 3, and the rotation of the first rollers 3 can effectively adjust the rotation of the steel pipe, so that the surface of the steel pipe can be fully processed, and the first double-axis motor 15 is started to drive the two threaded shafts 13 connected to it to rotate, and the rotation of the two threaded shafts 13 will cause the inverted L-shaped sliders 4 on the surface to move relative to each other, and the relatively moving inverted L-shaped sliders 4 will push the adjusting rod 8 to move, and the movement of the adjusting rod 8 will push the clamping plate 5 to rotate through the fixed block 7, so that the rubber pad 6 contacts the surface of the steel pipe, and finally the steel pipe can be effectively clamped and fixed by the four first rollers 3, the four clamping plates 5 and the four rubber pads 6.

[0020] The clamping mechanism has a steel pipe rotation and movement adjustment structure, which can conveniently and effectively rotate and move the placed steel pipe, thereby facilitating comprehensive processing operations on the surface of the steel pipe and improving the convenience and efficiency of steel pipe processing.
