AI Technical Summary
Existing clamping devices for flattened steel pipes have strong structural rigidity, poor adaptability, and are cumbersome to operate. They are difficult to adapt to workpieces of different sizes and shapes, and the clamping process is prone to workpiece misalignment or insufficient clamping force, which affects processing accuracy and efficiency.
A tooling fixture including a clamping base, a movable pressure plate, and a clamping force handle is designed. Through the linkage structure between the handle and the movable pressure plate, a fast and stable clamping state is achieved. The clamping force handle drives the movable pressure plate to change position, forming synchronous clamping and releasing operations.
This improves the clamping efficiency and ease of operation of flattened steel pipe parts, ensuring the positioning accuracy and processing quality of the workpiece.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a tooling fixture for flattening steel pipe parts. Background Technology
[0002] During industrial processing such as welding, forming, or assembly, flattened steel pipe parts often require stable clamping to ensure accurate positioning and processing quality. Existing clamping devices for flattened steel pipe parts are typically simple in structure, often employing a combination of a fixed pressure plate and a base, achieving clamping through external force. This results in problems such as high structural rigidity and poor adaptability, making it difficult to adapt to workpieces of different sizes and shapes.
[0003] Meanwhile, in existing fixtures, the clamping mechanism and the operating handle are mostly designed separately. When clamping or releasing the workpiece, the operator needs to manually coordinate multiple parts. This not only makes the operation steps cumbersome, but also makes the angle control unstable during the clamping process, which can easily cause workpiece misalignment or insufficient clamping force, affecting the accuracy and efficiency of subsequent processes. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a tooling fixture for positioning and clamping steel pipe flattening parts that is simple in structure, easy to install, and suitable for positioning and clamping steel pipe flattening parts. This fixture optimizes the cooperation structure between the fixture base, the movable pressure plate and the clamping force handle, so as to facilitate the rapid formation of a stable clamping state and improve the clamping efficiency and operation convenience of steel pipe flattening parts.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a tooling fixture for flattening steel pipes, including a fixture base, a movable pressure plate and a clamping force handle. The fixture base is provided with a handle mounting post and a pressure plate mounting block. The movable pressure plate is rotatably mounted on the pressure plate mounting block through a pressure plate pin. The clamping force handle is rotatably connected to the handle mounting post through a handle pin and forms a linkage relationship with the movable pressure plate, so that the clamping force handle can drive the movable pressure plate to change position during the swinging process.
[0006] Furthermore, the movable pressure plate is provided with a through hole, which is a through structure and its size is adapted to the handle mounting post. The through hole is sleeved on the outside of the handle mounting post, so that the movable pressure plate can rotate relative to the pressure plate pin in the through hole state.
[0007] Furthermore, the pressure plate pin passes through the side of the movable pressure plate and forms a hinge connection with the pressure plate mounting block. The pressure plate pin is located at one edge of the movable pressure plate, allowing the movable pressure plate to rotate relative to the fixture base.
[0008] Furthermore, a clamping gap is provided between the fixture base and the movable pressure plate. In the assembled state, the clamping gap is located on the lower side of the movable pressure plate and defines the space for accommodating the flattened steel pipe, so as to achieve the initial positioning in the clamping state.
[0009] Furthermore, the clamping force handle is positioned above the movable pressure plate, with both ends of the handle respectively engaging with the handle mounting post and the corresponding part of the movable pressure plate, for manually swinging to achieve the up-and-down opening and closing action of the pressure plate.
[0010] The beneficial effects of this utility model are:
[0011] This utility model forms a split mounting structure for the clamping handle and movable pressure plate by setting a handle mounting post and a pressure plate mounting block on the clamp base, which makes the assembly relationship of each component clear, the arrangement compact, and facilitates manufacturing and maintenance.
[0012] The present invention establishes a linkage between the clamping handle and the movable pressure plate, thereby achieving synchronous coordination between the handle action and the pressure plate action in terms of structure, which facilitates clamping control through a single operation.

[0017] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention in a schematic manner, and therefore only show the components relevant to the present invention.
[0018] like Figure 1As shown, this utility model provides a tooling fixture for flattening steel pipe parts, including a fixture base 1, a movable pressure plate 2, a clamping handle 3, a pressure plate pin 4, and a handle pin 5. The tooling fixture is used for positioning and clamping steel pipe flattening parts 6. The fixture base 1 is an integral structure, with a vertically arranged handle mounting post 11 and a pressure plate mounting block 12 arranged on the side. The movable pressure plate 2 has a through hole in the middle, which is fitted onto the outside of the handle mounting post 11 from above, and is rotatably connected to the pressure plate mounting block 12 through the pressure plate pin 4 at one end, allowing the movable pressure plate 2 to rotate around the pressure plate pin 4.
[0019] The clamping handle 3 is rotatably mounted on the upper part of the handle mounting post 11 via the handle pin 5 and is positioned above the movable pressure plate 2 for the operator to apply force. To achieve a linkage between the clamping handle 3 and the movable pressure plate 2, in this embodiment, a structural fitting part is provided between the lower part of the clamping handle 3 and the movable pressure plate 2. This fitting part is located on the upper surface of the pressure plate 2 and fits snugly against the lower contour line of the handle 3. When the clamping handle 3 swings around the handle pin 5, its lower contour structure remains in contact with the upper surface of the movable pressure plate, thereby driving the movable pressure plate to swing around the pressure plate pin 4 through contact pressure, achieving the clamping or releasing operation of the steel pipe flattening component 6.
[0020] like Figure 2 As shown, when the clamping force handle 3 is in the up-open position, the movable pressure plate 2 is in the open state relative to the clamp base 1. At this time, a clamping gap is formed between the clamp base 1 and the movable pressure plate 2, which makes it easy to place the steel pipe flattened part 6 into the clamping area.
[0021] like Figure 3 As shown, when the clamping handle 3 is pressed down to the clamping position, the movable pressure plate 2 rotates around the pressure plate pin 4 under the push of the structure abutting the lower part of the handle, and the gap between the fixture base 1 and the movable pressure plate 2 is reduced, thereby achieving the clamping and positioning of the steel pipe flattening piece 6.
[0022] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
