Description

Technical Field

[0001] This utility model relates to the field of pipe and profile processing technology, and in particular to a pipe and profile middle clamping device. Background Technology

[0002] Currently, in metal processing, profile cutting, and automated conveying production processes, the positioning and clamping of pipes and profiles is a crucial step in ensuring processing accuracy and operational safety. Traditional clamping structures mostly employ single-point or double-point clamping methods, which can only fix the workpiece in one direction, making it difficult to simultaneously clamp and limit the workpiece from multiple sides (top, bottom, left, and right). Especially when the workpiece is long or has a complex shape, problems such as unstable clamping, wobbling, and displacement often occur, leading to decreased processing accuracy or unstable equipment operation.

[0003] Existing pipe and profile clamping devices generally lack automatic adjustment capabilities in their structural design. For workpieces of different specifications and cross-sections, manual replacement of clamps or repeated adjustment of the clamping mechanism position is often required, which is not only cumbersome but also affects production efficiency. At the same time, problems such as asynchronous clamping mechanism movements and uneven clamping force distribution can also cause uneven stress on the workpiece, resulting in deformation or clamping failure.

[0004] Furthermore, while some devices can achieve multi-faceted clamping, the fixed clamping surfaces make the workpiece susceptible to frictional resistance during forward and backward movement, affecting the continuity of the feeding or transfer process. This frictional resistance is particularly problematic in automated production lines, causing equipment stoppages or poor feeding, failing to meet the requirements of fast and efficient production cycles, and reducing the overall line efficiency.

[0005] Therefore, there is an urgent need to provide a pipe and profile mid-clamping device that is compact in structure, coordinated in action, can achieve multi-directional synchronous clamping, and also ensures smooth movement of the workpiece. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a clamping device for the middle of pipes and profiles.

[0007] The purpose of this utility model is achieved as follows: a clamping device for the middle of a pipe or profile includes a support frame, the left side of which protrudes upward, an upper clamping plate that can move up and down is provided on the left side of the support frame, a movable plate that can move up and down is provided on the front side of the support frame, a lower clamping plate is provided at the upper end of the movable plate, and two symmetrically distributed side clamping plates that can move left and right are provided on the movable plate. The two side clamping plates move synchronously in opposite directions, and the upper ends of the two side clamping plates protrude from the upper ends of the lower clamping plate, with the upper clamping plate located above the lower clamping plate.

[0008] A first roller is rotatably mounted on the upper clamping plate. The lower clamping plate includes two second rollers, which are rotatably located at the upper end of the movable plate. The first roller is positioned above the two second rollers. A third roller is rotatably mounted on the inner upper part of each of the two side clamping plates.

[0009] Furthermore, a lifting mechanism one is fixedly installed on the front side of the support frame, and the upper clamping plate, which can move up and down, is located on the left side of the support frame. The lifting mechanism one drives the upper clamping plate to move up and down. A lifting mechanism two is installed on the support frame, and the lifting mechanism two drives the moving plate to move up and down.

[0010] Beneficial effects: This utility model has the following technical effects when used:

[0011] 1. Achieve stable clamping in multiple directions: Through the combined action of the upper clamping plate, the lower clamping plate, and two symmetrically arranged side clamping plates, the pipe or profile can be simultaneously limited and clamped in four directions: up, down, left, and right. This ensures the stability of the workpiece position during the clamping process, prevents shaking or displacement, and improves the stability and accuracy of the processing or conveying process.

[0012] 2. It has an adaptive adjustment function: the upper and lower clamping plates are independently controlled by lifting mechanism one and lifting mechanism two, respectively. It can automatically adjust the clamping height and spacing according to pipes and profiles with different diameters or cross-sectional dimensions. It has strong adaptability and good versatility and can meet the clamping needs of multiple specifications of pipes and profiles.

[0013] 3. Reliable synchronous clamping structure of side clamps: The drive mechanism drives the gear to mesh with the left and right racks, so that the two side clamps can move synchronously in opposite directions, ensuring that the clamping force on both sides is uniform and consistent, avoiding uneven pressure or unstable clamping on one side, and improving clamping accuracy and reliability.

[0014] 4. The roller structure design facilitates smooth conveying: Rotatable rollers (roller one, roller two, and roller three) are installed on the upper clamping plate, lower clamping plate, and side clamping plate. While achieving multi-face clamping and limiting, the pipe or profile is allowed to roll or move smoothly in the front and back direction, reducing the frictional resistance generated, facilitating continuous feeding, conveying, or positioning operations, and improving work efficiency.

[0015] 5. Compact structure, convenient control, and high reliability: The whole machine realizes lifting, clamping, and sliding through mechanical linkage. The structure is compact, the movements are coordinated, and it does not rely on a complex electrical control system. It has high reliability and is easy to maintain, making it suitable for widespread use in automated production lines or machining scenarios. Attached Figure Description

[0023] Example 1, such as Figure 1-3 As shown, the purpose of this utility model is achieved as follows: a clamping device for the middle of a pipe or profile includes a support frame 1, the left side of the support frame 1 protruding upwards, an upper clamping plate 2 that can move up and down is provided on the left side of the support frame 1, a movable plate 10 that can move up and down is provided on the front side of the support frame 1, a lower clamping plate is provided at the upper end of the movable plate 10, and two symmetrically distributed side clamping plates 3 that can move left and right are provided on the movable plate 10. The two side clamping plates 3 move synchronously in opposite directions, and the upper ends of the two side clamping plates 3 protrude from the upper end of the lower clamping plate. The upper clamping plate 2 is located above the lower clamping plate.

[0024] A first roller 7 is rotatably mounted on the upper clamping plate 2. The lower clamping plate includes two second rollers 6, which are rotatably located on the upper end of the movable plate 10. The first roller 7 is located above the two second rollers 6. A third roller 8 is rotatably mounted on the inner upper part of each of the two side clamping plates 3.

[0025] A lifting mechanism 9 is fixedly installed on the front side of the support frame 1. The upper clamping plate 2 is located on the left side of the support frame 1 and can move up and down. The lifting mechanism 9 drives the upper clamping plate 2 to move up and down. A second lifting mechanism 4 is installed on the support frame 1, which drives the moving plate 10 to move up and down.

[0026] The two side clamps 3 are movable left and right on the moving plate 10. The moving plate 10 is provided with a drive mechanism 5, which drives the two side clamps 3 to move synchronously in opposite directions.

[0027] The output end of the drive mechanism 5 is fixedly connected to the lower part of the left side clamping plate 3. The drive mechanism 5 drives the left side clamping plate 3 to move left and right. A gear 15 is rotatably mounted on the moving plate 10. A left rack 16 and a right rack 14 are fixedly mounted on the inner sides of the two side clamping plates 3, respectively. The left rack 16 and the right rack 14 mesh with the gear 15 from below and above, respectively. Pressure rollers 17 are symmetrically mounted on the upper and lower sides of the gear 15, and the outer sides of the left rack 16 and the right rack 14 are in contact with the outer sides of the pressure rollers 17, respectively.

[0028] When this application is in use, when the pipe or profile moves to the position between the upper clamping plate 2 and the lower clamping plate, the lifting mechanism 2 4 is controlled to drive the moving plate 10 to move up and down, thereby adjusting the height of the roller 2 6 on the lower clamping plate, so that the upper surface of the roller 2 6 fits with the lower surface of the pipe or profile, thereby providing bottom support for it.

[0029] By controlling the drive mechanism 5, the two side clamps 3 move synchronously towards the middle, so that the inner side of the side clamps 3 fits against the left and right sides of the pipe and profile. At the same time, the left and right positions of the pipe and profile are adjusted so that the center is located in the middle of the two side clamps 3, and the pipe and profile are clamped on both sides.

[0030] Then, by controlling the lifting mechanism 9, the upper clamping plate 2 is moved downward, so that the lower surface of the roller 7 on the upper clamping plate 2 is in contact with the upper surface of the pipe and profile, thereby limiting the upper surface of the pipe and profile and simultaneously clamping and limiting it in the vertical direction with the lower clamping plate.

[0031] The installation of rollers 7, 6, and 8 allows for clamping and limiting of pipes and profiles without affecting their forward and backward movement. The inclusion of a left rack 16, a right rack 14, a gear 15, and a pressure roller 17 enables the two side clamping plates 3 to move synchronously in opposite directions.

[0032] Example 2:

[0033] like Figure 4-5 As shown: A base frame 11 is provided on the right side of the support frame 1. The support frame 1 is slidably positioned on the base frame 11. A guide rail 12 is provided between the support frame 1 and the base frame 11, and the support frame 1 and the base frame 11 are slidably connected through the guide rail 12. A second drive mechanism 13 is provided between the support frame 1 and the base frame 11, and the second drive mechanism 13 drives the support frame 1 to move back and forth along the base frame 11. The support frame 1, which can move back and forth on the base frame 11, can clamp and limit the pipes and profiles while simultaneously driving the entire clamping device to move back and forth through the second drive mechanism 13. This avoids the risk of the end of the profile falling downwards due to its own weight because it is too far from the cutting equipment (existing technology, not described in detail). At the same time, the distance between the clamping mechanism and the cutting equipment can be adjusted as needed to adapt to the processing technology of pipes and profiles of different lengths.

[0034] The sliding guide rail structure allows for flexible device layout: the support frame and the base frame are slidably connected by guide rails and moved back and forth by the drive mechanism. The position of the clamping mechanism can be flexibly adjusted according to the processing station, feeding cycle, or production line position, improving the flexibility of equipment layout and facilitating linkage with other processing equipment.

[0035] The lifting mechanism, drive mechanism, and control system involved in this application can all be implemented using existing mature mechanical, electric, hydraulic, or pneumatic structures. The specific control method, drive principle, and structural form are not limited, as long as they have the ability to achieve the functions of this application. The action coordination, signal transmission, and control logic between the various mechanisms can be accomplished through conventional controllers, electrical circuits, or sensing devices, which are well-known technologies in the field and will not be elaborated upon. The electrical connections, power supply arrangements, circuit control, and signal feedback methods involved in this application are all existing technologies, and suitable components and connection methods can be selected according to actual usage requirements. At the same time, structures such as guide rail sliding connection, gear and rack transmission, pressure roller support, and roller rotation are all common mechanical components, and their processing forms and installation methods can be equivalently replaced without affecting the core innovative content of this application.
