Description

Technical Field

[0001] This utility model relates to the field of tooling fixture technology, and in particular to an adjustable steel positioning fixture. Background Technology

[0002] A steel positioning fixture is a tool specifically designed to fix and precisely position steel workpieces during machining or assembly. It ensures that the steel maintains the correct position and orientation during operations such as cutting, welding, drilling, and milling, thereby guaranteeing consistent machining accuracy and product quality. Furthermore, a good positioning fixture can improve work efficiency, reduce scrap rates, and enhance operational safety.

[0003] In the existing technology, positioning fixtures used for steel processing are usually fixed in structure and have a single function, making it difficult to adapt to the processing needs of diverse workpieces. Most fixtures only have the ability to adjust in one direction and cannot flexibly adjust parameters such as height and angle. They lack multi-degree-of-freedom coordinated adjustment functions, which leads to problems such as poor adaptability and low versatility in practical applications, seriously limiting the applicability and processing efficiency of the fixtures.

[0004] To address the aforementioned issues, an adjustable steel positioning clamp is needed. Utility Model Content

[0005] To overcome the shortcomings of fixed positioning fixtures, this utility model provides an adjustable steel positioning fixture.

[0006] The technical solution of this utility model: An adjustable steel positioning clamp includes a base, connecting frames, lead screws, first connecting rods, guide rods, lifting blocks, connecting frames, damping shafts, mounting frames, cylinders, motors, and a first connecting plate. The base has connecting frames symmetrically connected to the left and right sides, and lead screws rotatably connected inside the two front connecting frames. The other ends of both lead screws are rotatably engaged with the base. First connecting rods are connected to both lead screws, and both first connecting rods pass through corresponding connecting frames. Guide rods are connected inside the two rear connecting frames. The other end of each rod is connected to the base. Lifting blocks are threaded onto both lead screws, and lifting blocks are also slidably connected onto both guide rods. A connecting frame is connected between two lifting blocks on the same left and right side. Damping shafts are rotatably connected to each other in both connecting frames. Mounting frames are connected between two damping shafts on the same left and right side. Cylinders are installed inside both mounting frames. Motors are installed inside both connecting frames. The output shafts of both motors pass through the corresponding connecting frames and are connected to the corresponding damping shafts. The telescopic ends of both cylinders are connected to the first connecting plate.

[0007] Furthermore, it also includes a second connecting plate, a sliding rod, a spring, a fixed plate, a rotating rod, and a connecting block. Each first connecting plate is symmetrically connected to a second connecting plate on its outer side, and a sliding rod is slidably connected inside each second connecting plate. A spring is provided between each sliding rod and the corresponding second connecting plate. Fixed plates are provided on the inner sides of both first connecting plates, and rotating rods are symmetrically connected to the outer sides of both fixed plates. A connecting block is connected to each rotating rod, and each rotating rod engages with the corresponding connecting block.

[0008] Furthermore, it also includes a second connecting rod, with each sliding rod connected to a second connecting rod.

[0009] Furthermore, it also includes a protective shell, with a protective shell connected inside each connecting frame.

[0010] Furthermore, it also includes sponge pads, with sponge pads connected to the inner sides of both fixing plates.

[0011] Furthermore, the base has multiple mounting holes.

[0012] The beneficial effects of this utility model are as follows: 1. Through the coordinated operation of the lead screw and the guide rod, the lifting block is driven to move smoothly along the guide direction, effectively ensuring the accurate positioning and operational stability of the clamping assembly at different heights; at the same time, the motor drives the damping shaft to rotate, driving the mounting frame and cylinder as a whole to achieve flexible adjustment at multiple angles, significantly enhancing the adaptability of the fixture to irregularly shaped workpieces or complex processing postures. The fixture adopts a double-sided synchronous clamping structure, combined with a cylinder drive method, which not only ensures the uniform application of clamping force, but also greatly improves the clamping reliability of the workpiece, effectively preventing displacement and loosening caused by unstable clamping during processing, thereby avoiding accuracy deviations or safety accidents.

[0013] 2. Through the modular mounting structure of the fixing plate, by setting up a quick-replaceable fixing plate assembly, and combining the snap-fit ​​mechanism of the sliding rod and the connecting block, the fixture can be efficiently adapted to steel with different cross-sectional shapes (such as round, rectangular, H-beams, etc.). This structure not only simplifies the fixture replacement process and significantly improves the ease of operation, but also enhances the versatility and flexibility of the fixture, meeting the clamping needs of diverse workpieces.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0021] Example: An adjustable steel positioning clamp, such as Figures 1-5As shown, the system includes a base 1, connecting frame 2, lead screw 3, first connecting rod 301, guide rod 4, lifting block 5, connecting frame 6, damping shaft 7, mounting frame 8, cylinder 9, motor 10, first connecting plate 11, second connecting plate 12, sliding rod 13, spring 14, fixing plate 15, rotating rod 16, connecting block 17, second connecting rod 18, protective shell 19, and sponge pad 20. The base 1 has multiple mounting holes. Connecting frames 2 are symmetrically connected to the base 1, with lead screws 3 rotatably connected inside the two front connecting frames 2. The other ends of both lead screws 3 are rotatably engaged with the base 1. Each rod 3 is connected to a first connecting rod 301, and both first connecting rods 301 pass through the corresponding connecting frame 2. Guide rods 4 are connected inside the two rear connecting frames 2, and the other ends of the two guide rods 4 are connected to the base 1. The guide rods 4 guide the lifting blocks 5. Lifting blocks 5 are threaded onto both lead screws 3, and lifting blocks 5 are also slidably connected to both guide rods 4. A connecting frame 6 connects between two lifting blocks 5 on each left and right side. Damping shafts 7 are rotatably connected to both sides of each connecting frame 6. Mounting frames 8 are connected between the two damping shafts 7 on each left and right side. Each component is equipped with a cylinder 9, and a motor 10 is installed within each of the two connecting frames 6. The output shafts of the two motors 10 pass through the corresponding connecting frames 6 and are connected to the corresponding damping shafts 7. The telescopic ends of the two cylinders 9 are each connected to a first connecting plate 11. Each first connecting plate 11 has a second connecting plate 12 symmetrically connected to its outer front and rear sides. Each second connecting plate 12 has a sliding rod 13 slidably connected within it. The sliding rod 13 can lock the connecting block 17 in place. A spring 14 is connected between each sliding rod 13 and the corresponding second connecting plate 12. The inner sides of both first connecting plates 11 are provided with fixing plates 15. The fixing plate 15 is used to clamp the steel. The outer sides of the two fixing plates 15 are symmetrically connected with rotating rods 16. Each rotating rod 16 is connected with a connecting block 17. Each rotating rod 16 is engaged with the corresponding connecting block 17. Each sliding rod 13 is connected with a second connecting rod 18. The second connecting rod 18 makes it easy for the operator to pull the sliding rod 13 to move and release the locking state. Each connecting frame 6 is connected with a protective shell 19. The inner sides of the two fixing plates 15 are connected with sponge pads 20. The sponge pads 20 can increase the friction of the fixing plates 15 when clamping and protect the surface of the steel from being scratched.

[0022] When positioning and clamping steel of different sizes or shapes, the operator first manually rotates the first connecting rod 301 on the left side according to the height requirements of the steel, causing the lead screw 3 to rotate. Since the lifting block 5 and the lead screw 3 are threaded together, and the guide rod 4 guides the lifting block 5, the rotation of the lead screw 3 will drive the lifting block 5 to move up and down along the guide rod 4, thereby driving the connecting frame 6, damping shaft 7, mounting frame 8, and cylinder 9 to achieve overall height adjustment. When the cylinder 9 drives the clamping assembly to rise to a suitable height for placing the steel, the rotation of the first connecting rod 301 is stopped. After completing the height adjustment operation, if it is necessary to adjust the clamping angle according to the shape of the steel, the motor 10 installed inside the connecting frame 6 can be started. The output shaft of the motor 10 is connected to the damping shaft 7 through a coupling, driving the damping shaft 7 to rotate, thereby causing the mounting frame 8 and cylinder 9 to rotate around the damping shaft 7. After rotating to the appropriate angle, the motor 10 is turned off, and the self-locking characteristic of the damping shaft 7 is used to maintain the current angle unchanged, completing the angle adjustment. Next, the operator selects the matching fixing plate 15 according to the specific cross-sectional shape of the steel to be clamped (such as round, rectangular, H-beam, etc.), and then... It is installed inside the first connecting plate 11. At this time, the two rotating rods 16 and the connecting block 17 are pre-passed through the through slots on the second connecting plate 12. During the installation process, the operator first pulls the front second connecting rod 18 upward, causing the sliding rod 13 to move upward against the force of the spring 14. Then, the rotating rod 16 is rotated so that the connecting block 17 rotates to the position below the sliding rod 13. The second connecting rod 18 is released, and the spring 14 pushes the sliding rod 13 to reset, so that its bottom is locked into the groove on the top of the connecting block 17, thereby locking one side of the fixing plate 15. The above steps are repeated for the rear connecting plate 15. Block 17 performs the same snap-fit ​​operation to complete the installation of the fixing plate 15 on this side. The adjustment method of the clamping mechanism on the right side is the same as that on the left side. After completing the height and angle adjustment and the installation of the fixing plate 15 in sequence, the entire fixture has the ability to adapt to the target steel. Finally, the steel to be processed is placed stably on the base 1, and the cylinders 9 on both sides are started. Their telescopic ends push the first connecting plate 11 and the fixing plate 15 to move towards the steel until the fixing plates 15 on both sides simultaneously contact and clamp the surface of the steel. At this time, the steel is firmly positioned, which facilitates subsequent processing operations such as welding, cutting, and drilling.
