Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology, specifically to a positioning fixture for machining irregularly shaped steel. Background Technology

[0002] The positioning fixture for irregular steel processing is a special device designed for processing irregular steel materials. Through the coordinated action of positioning elements and clamping devices, it fixes irregularly shaped and complex-sized irregular steel workpieces on machine tools or processing platforms, ensuring that they maintain a stable position and posture during processing.

[0003] Referring to the existing Chinese patent with publication number CN215469697U, a tooling for processing irregular steel structures is disclosed, relating to the field of irregular steel processing technology. It includes a base, with a mounting seat fixedly connected to the top of the base. The mounting seat has a double-ended screw inside, and a threaded sleeve is provided on the double-ended screw, with a brush located below the threaded sleeve. A support plate is fixedly connected to the top of the threaded sleeve, and a drive motor is provided on one side of the support plate. A folding plate is disposed on the surface of the mounting seat. The mounting seat has an inverted "U"-shaped structure design, and its interior is hollow. The mounting seat and the double-ended screw are perpendicular to each other.

[0004] The aforementioned fixture for processing irregularly shaped steel structures can prevent processing debris from falling into the mounting base and onto the double-ended screw, thus avoiding the problem of difficult cleaning. Its overall structure is simple, and the fixture is easy to disassemble, facilitating repair and replacement of damaged fixtures. However, this fixture still has some drawbacks. For example, it can only clamp some square irregularly shaped steel pieces and cannot effectively clamp other irregularly shaped steel pieces, such as those used in construction sites where tower cranes rely on triangular structures for stability, solar water heater supports which are often triangular to bear weight, and high-voltage power line towers which incorporate triangular shapes to resist strong winds. The aforementioned device cannot effectively clamp triangular steel pieces when processing their surfaces. Therefore, we need to propose a positioning fixture for processing irregularly shaped steel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides a technical solution: a positioning fixture for processing irregularly shaped steel, including a base plate 1, characterized in that: a shell 2 is provided above the base plate 1, and the inner wall of the shell 2 is provided with a length adjustment mechanism for adapting to the processing of irregularly shaped steel of different lengths; the length adjustment mechanism includes a first slide rail 3, which is disposed on the inner wall of the shell 2, and a first slider 4 is provided on the surface of the first slide rail 3 and is adapted to the first slide rail 3; processing grooves 5 are provided on the surface of the shell 2 and penetrate through the shell 2. By adjusting the position of the first slider 4 on the surface of the first slide rail 3, it can adapt to triangular steel of different lengths, and the processing grooves 5 are provided to facilitate processing.

[0023] The housing 2 is internally equipped with a height adjustment mechanism to accommodate different processing heights of the processing equipment during the processing of irregularly shaped steel. The height adjustment mechanism includes a mounting plate 6, which is disposed inside the housing 2. Both ends of the mounting plate 6 are positioned on the surface of the first slider 4. A second slide rail 7 is provided on one side of the mounting plate 6, and a second slider 8 is mounted on the surface of the second slide rail 7 and is adapted to fit the second slide rail 7. The position of the second slider 8 on the surface of the second slide rail 7 is adjusted to accommodate different processing heights of the processing equipment during the processing of irregularly shaped steel.

[0024] The housing 2 has an internal clamping mechanism for holding triangular steel pieces within an irregularly shaped steel frame. The clamping mechanism includes a placement plate 9, which is located inside the housing 2. One side of the placement plate 9 is positioned on the surface of the second slider 8. A through hole 10 is formed on the surface of the placement plate 9, penetrating through it. A servo cylinder 11 is located on the side of the placement plate 9 furthest from the second slider 8, and a clamping plate 12 is attached to the output end of the servo cylinder 11. When the triangular steel piece needs to be clamped, it is inserted through the through hole 10, and the output end of the servo cylinder 11 extends to push the clamping plate 12 to clamp the three sides of the triangular steel piece.

[0025] A rotating mechanism is provided on one side of the housing 2 for rotating the housing 2 to adapt to different processing positions; the rotating mechanism includes a connecting rod 13, which is provided on one side of the housing 2. A limiting hole 14 is opened inside the connecting rod 13, which passes through the connecting rod 13 and one side of the housing 2. The position of the limiting hole 14 corresponds to the through hole 10. A first pulley 15 is provided on the surface of the connecting rod 13, and a power mechanism is provided below the first pulley 15.

[0026] The power mechanism includes a second pulley 16, which is positioned below the first pulley 15. A belt 17 is fitted onto the surfaces of both the first pulley 15 and the second pulley 16. A servo motor 18 is mounted on one side of the second pulley 16 and connected to its output. When different machining surfaces need to be adjusted, the servo motor 18 starts rotating, driving the second pulley 16. This rotation, via the belt 17, drives the first pulley 15, causing the connecting rod 13 to rotate. This allows the outer casing 2 to change its machining surface without removing the triangular steel piece.

[0027] A support mechanism for supporting the rotating mechanism is provided on the top of the base plate 1. The support mechanism includes a support rod 19, which is located on the top of the base plate 1.

One side of the servo motor 18 is installed on one side of the support rod 19. The baffle 22 is used to limit the connecting rod 13 to prevent it from falling off the inner wall of the bearing 21.
