Technical Field

[0002] In the pipe processing industry, the feeding of square and round pipes is a crucial part of automated production lines. Existing clamping devices for square and round pipes suffer from the following drawbacks: poor versatility: most clamping devices are only compatible with a single type of pipe (square or round), requiring disassembly and replacement of the clamps when changing pipes, resulting in cumbersome operations and reduced production efficiency; insufficient posture adjustment capability: it is difficult to flexibly adjust the clamping angle of the pipes according to the conveyor line layout or processing station requirements, limiting feeding adaptability; complex structure: some clamping structures are redundant, and the layout of drive components is unreasonable, increasing equipment size and maintenance difficulty. Therefore, there is an urgent need to design a clamping device that combines versatility, posture adjustability, and a compact structure to solve these problems. To this end, we propose a new clamping mechanism for pipe feeding. Utility Model Content

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, this utility model provides a clamping mechanism for pipe feeding, including: a fixed base 1, a clamping module 2 for clamping square or round pipes, and a mounting base 3; the bottom of the fixed base 1 is provided with: a first drive module 4 for driving the mounting base 3 to rotate, and a bearing seat 5; the output end of the first drive module 4 passes through the bearing seat 5 and is fixedly connected to the mounting base 3; the mounting base 3 is provided with a second drive module 6 for driving the clamping module 2; the output end of the second drive module 6 is connected to the clamping module 2 in a transmission manner; the fixed base 1 is provided with a plurality of mounting holes 7 for screws to pass through; in this embodiment, the fixed base 1 is mounted on the frame of the pipe feeding equipment through the mounting holes 7 and screws; during operation, the first drive module 4 drives the mounting base 3 to rotate, thereby driving the second drive module 6 and the clamping module 2 on the mounting base 3 to perform a flipping operation, so as to realize the flipping and conveying operation of the pipe; the overall structure is stable and easy to install, and can realize the automatic flipping and feeding operation of square and round pipes, while the clamping angle of the clamping module 2 can be flexibly adjusted, effectively improving the production and processing efficiency.

[0019] Further, the clamping module 2 includes: a first clamping arm 21, a second clamping arm 22, a first transmission arm 23, a second transmission arm 24, and a mounting frame 25; the mounting frame 25 is fixedly connected to the second drive module 6; the mounting frame 25 is provided with a mounting groove; a first column 26 and a second column 27 are respectively provided at both ends of the mounting groove; the first transmission arm 23 and the second transmission arm 24 are symmetrically installed in the gap between the first column 26 and the second column 27; the assembly end of the first clamping arm 21 is hinged to one end of the first transmission arm 23 and the first column 26 respectively; the first... The other end of the transmission arm 23 is hinged to the mounting bracket 25, and its extended end is provided with teeth 29 for transmission connection with the output end of the second drive module 6; the clamping surface of the first clamping arm 21 is provided with an inwardly concave arc-shaped transition structure 28; the assembly end of the second clamping arm 22 is hinged to one end of the second transmission arm 24 and the second column 27; the other end of the second transmission arm 24 is hinged to the mounting bracket 25, and its extended end is provided with teeth 29 for transmission connection with the output end of the second drive module 6; the clamping surface of the second clamping arm 22 is provided with an inwardly concave arc-shaped transition structure 28.

[0020] In this embodiment, as Figure 1-3As shown, the mounting bracket 25 is connected to the outer wall of the assembly end of the second drive module 6. During operation, when the second drive module 6 operates in the forward direction (pushing out), it engages with the teeth 29 on the first transmission arm 23 and the second transmission arm 24 to push the two clamping arms on both sides outward around their hinge points with the mounting bracket, thus opening the clamping arms. When the second drive module 6 operates in the reverse direction (retracting), it engages with the teeth 29 on the first transmission arm 23 and the second transmission arm 24 to pull the two clamping arms on both sides inward around their hinge points with the mounting bracket. The arc-shaped transition structure 28 on the clamping surfaces of the two clamping arms conforms to the edge of the square tube or the arc surface of the round tube, completing the stable clamping operation of the square or round tube.

When working, when the piston rod extends, it pushes the two clamping arms on both sides to rotate outward around the hinge points with the mounting frame respectively, so as to open the clamping arms. When the piston rod retracts, it pulls the clamping arms on both sides to rotate inward around the hinge points with the mounting frame 25. The arc transition structure 28 of the clamping arms fits against the edge of the square tube or the arc surface of the round tube to complete the stable clamping operation of the square tube or the round tube.

[0023] Furthermore, the first drive module 4 includes a drive motor 41 and a transmission shaft 42; the drive motor 41 is mounted on the bottom of the fixed base 1, and its output end is connected to the input end of the transmission shaft 42; the output end of the transmission shaft 42 passes through the bearing seat 5 and is fixedly connected to the mounting base 3; the transmission shaft 42 is rotatably mounted on the bearing seat 5.

[0024] In this embodiment, as Figure 1-3 As shown, the drive motor 41 is a servo motor. When working, the drive motor 41 drives the transmission shaft 42 to rotate, and the transmission shaft 42 drives the mounting base 3 fixedly connected to it to rotate, thereby driving the second drive module 6 and the clamping module 2 on the mounting base 3 to rotate, so as to realize the flipping, clamping and conveying operation of the pipe. At the same time, the clamping angle of the clamping module 2 can be flexibly adjusted.
