Description

Technical Field

[0001] This invention relates to the field of dimensional measurement equipment technology, and more specifically, to a dimensional calibration device for prefabricated building components. Background Technology

[0002] Prefabricated building components refer to parts used for reinforcement, support, connection, and transmission in building engineering, including: steel structures, cast iron parts, bearings, fasteners, expansion bolts, nuts, brackets, pipes, valves, pumps, wire ropes, and safety protection equipment. Among them, steel structures are an important component of prefabricated building components, including: H-beams, I-beams, channel steel, angle steel, flat steel, etc. They are characterized by high strength, good rigidity, light weight, reusability, and convenient assembly and disassembly, and are widely used in the assembly and splicing of large buildings, bridges, and towers.

[0003] When steel structures are put into construction, the lengths of prefabricated building components such as steel structures and bolts with length requirements need to be measured and calibrated according to the building's conditions. However, the current method usually involves operators measuring the dimensions of prefabricated building components with a hand measuring tape. Prefabricated building components that are longer than the specified length are marked at the cutting positions. After the cutting positions are marked, they are cut by a cutting machine to obtain the required dimensions. However, the accuracy of operators measuring steel structures with hand measuring tapes is poor. For some building locations that require high precision, even a slight deviation can make it difficult to complete the assembly and construction of the steel structure. Summary of the Invention

[0042] 1. In this invention, a fourth motor installed on the frame drives the drive gear and the reduction gear to rotate. When the reduction gear rotates, it drives the moving toothed belt and the calibration platform to move. When the calibration platform moves, it drives the larger building component and the indicator arrow to move. When the indicator arrow moves, the length information of the larger building component can be obtained by observing the calibration ruler, thereby realizing the measurement of the length of the larger building component.

[0043] 2. In this invention, after the length of a larger building component is measured, the positioning block is fixed by a third electric cylinder on the moving frame, and the rotating shaft and cutting blade are rotated by a first motor on the cutting frame, thereby cutting the larger building component and thus calibrating and correcting the excessively long larger building component.

[0044] 3. In this invention, smaller building components are supported by a screening rack on a screening plate, and a first electric cylinder on the screening plate drives a pressure plate to descend, clamping the smaller building components between the screening plate and the pressure plate. A second electric cylinder descends, causing the screening plate to tilt, so that smaller building components that are not long enough fall down, while smaller building components that are of the correct length remain between the screening plate and the pressure plate, thereby achieving the calibration of smaller building components.

[0045] Compared to existing technologies, this equipment facilitates the calibration of building components with different specifications and length requirements, thereby improving the accuracy of building components and construction efficiency. Attached Figure Description

[0056] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0057] like Figures 1-8 As shown, this embodiment proposes a prefabricated building component size calibration device, including a frame 1, and further including: a calibration table 2, a calibration ruler 3, a screening mechanism, a positioning mechanism and a cutting mechanism. The calibration table 2 is slidably disposed in the frame 1. A moving mechanism is provided on the calibration table 2 to drive the calibration table 2 to move. The calibration ruler 3 is disposed on the frame 1. An indicator arrow 4 is provided on the calibration table 2.

[0058] The screening mechanism is mounted on the frame 1. The screening mechanism includes a screening plate 5, which is rotatably mounted inside the frame 1. A pressure plate 6 is slidably mounted on the screening plate 5 for dimensional calibration of building components. The screening mechanism also includes a screening frame 8, a pull plate 11, a first electric cylinder 12, and a second electric cylinder 13. Multiple screening frames 8 are provided, which are slidably mounted on the screening plate 5. A blocking ring 9 is provided on the screening frame 8, and a tension spring 10 is provided between the blocking ring 9 and the screening plate 5. The pull plate 11 is slidably mounted inside the pressure plate 6, and the bottom end of the pull plate 11 is flush with the bottom end of the pressure plate 6. The first electric cylinder 12 is mounted on the screening plate 5, and the pressure plate 6 is located at the output end of the first electric cylinder 12. The second electric cylinder 13 is mounted on the frame 1, and a slider 14 is provided at the output end of the second electric cylinder 13. The slider 14 is slidably mounted on the screening plate 5.

[0059] When it is necessary to calibrate smaller building components such as bolts, the pull plate 11 that slides on the pressure plate 6 is first opened, and then the bolts to be calibrated are poured into the multiple screening racks 8. Since there are nuts on the bolts, the nuts are placed between two adjacent screening racks 8. Then the pull plate 11 is closed, and the pressure plate 6 is lowered by the first electric cylinder 12 set on the screening plate 5, thereby clamping the bolts of qualified length between the screening plate 5 and the pressure plate 6. Then the screening plate 5 is lowered and tilted by the second electric cylinder 13 set on the frame 1, so that the bolts that are too short to be clamped fall down, thus leaving qualified bolts between the screening plate 5 and the pressure plate 6.

[0060] It should be further added that the screening frame 8 slides on the screening plate 5 and is held in a high position by the pull of the tension spring 10. When the pressure plate 6 descends, it presses down the screening frame 8, so that the bolt can be clamped between the screening plate 5 and the pressure plate 6. When the pressure plate 6 rises, the screening frame 8 is pulled back by the tension spring 10, so that the screening frame 8 returns to its previous position to continue to support the bolt.

[0061] The bottom surface of the pull plate 11 is flush with the bottom surface of the top plate. When the pull plate 11 is closed, the bottom surface of the pressure plate 6 can be kept at a level flatness, so that the bolts at any position on the entire screening plate 5 can be clamped.

[0062] The positioning mechanism is mounted on the frame 1. The positioning mechanism includes a positioning block 7, which is mounted on the frame 1 and is used to position the calibrated building components. The positioning mechanism also includes a moving frame 15, a third electric cylinder 16, and a drive mechanism. The moving frame 15 is slidably mounted on the frame 1, the third electric cylinder 16 is mounted on the moving frame 15, the positioning block 7 is mounted on the output end of the third electric cylinder 16, and the drive mechanism is used to drive the moving frame 15 to move.

[0063] The moving mechanism includes a moving toothed belt 28, a reduction gear 29, a drive gear 30, and a fourth motor 31. The moving toothed belt 28 is mounted on the calibration platform 2. The reduction gear 29 is rotatably mounted inside the frame 1 and meshes with the moving toothed belt 28. The drive gear 30 is rotatably mounted inside the frame 1 and meshes with the reduction gear 29. The fourth motor 31 is mounted on the frame 1, and the drive gear 30 is mounted on the output end of the fourth motor 31.

[0064] In the calibration of larger building components such as I-beams, the I-beams are first placed on the calibration platform 2. Then, the fourth motor 31 on the frame 1 drives the drive gear 30 and the reduction gear 29 to rotate. When the reduction gear 29 rotates, it drives the calibration platform 2 to move. When the calibration platform 2 moves, it drives the indicator arrow 4 to move. When the indicator arrow 4 moves, the length of the I-beam can be obtained by observing the calibration ruler 3. After the calibration platform 2 has moved to the specified length, the third electric cylinder 16 on the moving frame 15 drives the positioning block 7 to descend, thereby causing the positioning block 7 to die-cast the I-beam.

[0065] It should be further added that a wedge-shaped baffle is provided on the calibration platform 2. When calibrating the I-beam, one end of the I-beam is pressed against the wedge-shaped baffle. When one end of the I-beam is fully pressed against the wedge-shaped baffle, the other end of the I-beam is placed parallel to the calibration platform 2, and the I-beam is in a parallel state and will not tilt. When the calibration platform 2 is not moving, the position indicated by the indicator arrow 4 on the calibration ruler 3 is zero. When the calibration platform 2 moves, since the indicator arrow 4 is fixed on one end of the calibration platform 2, the movement of the calibration platform 2 drives the indicator arrow 4 to move, thereby moving the indicator arrow 4 on the calibration ruler 3. When the calibration platform 2 stops, the indicator arrow 4 stops on the scale of the calibration ruler 3, and the length of the I-beam can be measured.

[0066] The cutting mechanism is mounted on the frame 1 and is used to cut and straighten excessively long building components. The cutting mechanism includes: a sliding plate 17, a cutting frame 18, a cutting blade 20, a first motor 21, an adjusting screw 22, a second motor 23, and a fourth electric cylinder 24. The moving frame 15 has a sliding groove, and the sliding plate 17 is slidably mounted in the sliding groove. The cutting frame 18 is mounted on the sliding plate 17, and a rotating shaft 19 is rotatably mounted on the cutting frame 18. The cutting blade 20 is mounted on the rotating shaft 19 and is in contact with the positioning block 7. The first motor 21 is mounted on the cutting frame 18, and the rotating shaft 19 is mounted on the output end of the first motor 21. The adjusting screw 22 is rotatably mounted in the moving frame 15. The sliding plate 17 has a screw hole and is threadedly connected to the adjusting screw 22. The second motor 23 is mounted on the moving frame 15, and the adjusting screw 22 is mounted on the output end of the second motor 23. The fourth electric cylinder 24 is mounted on the sliding plate 17, and the cutting frame 18 is mounted on the output end of the fourth electric cylinder 24.

[0067] In this process, after the H-beam is pressed onto the calibration table 2 by the positioning block 7, the first motor 21 on the cutting frame 18 drives the rotating shaft 19 and the cutting blade 20 to rotate. Then, the fourth electric cylinder 24 on the slide plate 17 drives the cutting frame 18 to descend, which in turn drives the cutting blade 20 to descend and cut the H-beam. During the cutting of the H-beam, the second motor 23 on the moving frame 15 drives the adjusting screw 22 to rotate, which in turn drives the slide plate 17 to slide in the groove, so that the cutting blade 20 moves while cutting the H-beam, achieving the effect of completely cutting the H-beam.

[0068] It should also be noted that the cutting blade 20 is attached to the positioning block 7. When the positioning block 7 presses down to fix the I-beam, the side that is attached to the cutting blade 20 is at the position where the I-beam is measured. When the cutting blade 20 cuts the I-beam, the measured dimension is between the positioning block 7 and the cutting blade 20, which allows for more precise cutting of the I-beam.

[0069] The drive mechanism includes a drive block 25, a drive screw 26, and a third motor 27. The drive block 25 is mounted on the movable frame 15, and the drive screw 26 is rotatably mounted inside the frame 1. The drive block 25 has a screw hole and is threadedly connected to the drive screw 26. The third motor 27 is mounted on the frame 1, and the drive screw 26 is located at the output end of the third motor 27.

[0070] The third motor 27 installed on the frame 1 drives the drive screw 26 to rotate. When the drive screw 26 rotates, it drives the drive block 25 and the moving frame 15 to move, thereby moving the positioning and cutting position.

[0071] It should also be noted that, for example, if the I-beam needs to be one meter long, when the calibration table 2 moves to the length of one meter, the third motor 27 drives the moving frame 15 to move, so that the side of the positioning block 7 that is in contact with the cutting blade 20 moves to the position of one meter, and then the positioning block 7 fixes the I-beam, thereby improving the accuracy of the I-beam cutting.

[0072] A welding mechanism is provided on the frame 1. The welding mechanism includes a slide 32 and a welding machine 33. The slide 32 is slidably mounted on the frame 1, and the welding machine 33 is mounted on the slide 32. A welding torch 34 is provided on the welding machine 33.

[0073] If a longer I-beam is needed, but the length of the I-beam is insufficient, welding machine 33 and welding torch 34 are required to weld the I-beam to extend its length.

[0074] It should also be noted that the difficulty of welding varies depending on the type of building components, so the operator needs to hold the welding gun 34 during welding.

[0075] The frame 1 is provided with a feeding chute, and the feeding chute is provided with a feeding hopper 35 to facilitate the discharge of unqualified building components that have been screened out.

[0076] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
