Description

Technical Field

[0001] This utility model relates to the field of angle calibration technology, specifically to a device for calibrating the cutting angle of metal materials and steel structures. Background Technology

[0002] In the cutting and processing of metal structures, the accuracy of angles directly affects the welding quality of components and the safety of the project. Traditional angle calibration often relies on manual positioning using protractors or simple clamps. Manual positioning and reading are prone to visual errors, resulting in poor calibration accuracy. Furthermore, the fixing devices are prone to displacement, requiring repeated adjustments of the measuring tools. This operation is cumbersome and difficult to stably fix on large components. At the same time, the lack of an integrated angle adjustment and locking structure makes it impossible to quickly and accurately switch angles. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

[0003] The purpose of this utility model is to provide a metal material steel structure cutting angle calibration device to solve the problems mentioned in the background art. In traditional angle calibration, the angle calibration mostly relies on manual positioning using a protractor or simple clamps. Manual positioning and reading are prone to visual errors, resulting in poor calibration accuracy. In addition, the fixing device is prone to displacement, so the measuring tool needs to be adjusted repeatedly, which is cumbersome and difficult to fix stably on large components. At the same time, it lacks an integrated angle adjustment and locking structure, making it impossible to switch angles quickly and accurately.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a metal material steel structure cutting angle calibration device, including a crossbar, a fixed bearing installed at one end of the crossbar, an installation rod installed on one side of the outer wall of the fixed bearing, and an angle adjustment structure installed at the upper end of the crossbar and the installation rod.

[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 Figure 1-4 This utility model provides a technical solution:

[0023] In this technical solution, a metal material steel structure cutting angle calibration device includes a crossbar 1, a fixed bearing 2 installed at one end of the crossbar 1, an installation rod 3 installed on one side of the outer wall of the fixed bearing 2, and an angle adjustment structure installed at the upper end of the crossbar 1 and the installation rod 3. The angle adjustment structure includes a positioning plate 4, a scale plate 5, several slots 6 and three support rods 7.

[0024] The two ends of the positioning plate 4 are connected to the outer side of the upper wall of the crossbar 1 and the mounting rod 3, respectively. The two ends of the scale plate 5 are connected to the inner side of the upper wall of the crossbar 1 and the mounting rod 3, respectively, and are located inside the positioning plate 4. Several slots 6 are evenly opened on the outer wall of the positioning plate 4. One end of each of the three support rods 7 is fixedly connected to the outer wall of the fixed bearing 2, and the other end of each rod passes through the scale plate 5 and is fixedly connected to the inner wall of the positioning plate 4.

[0025] In this technical solution, when calibrating the angle of the steel structure cutting position, the operator first adjusts the rotating measuring structure to the specified angle according to the cutting angle requirements of the steel structure. The rotation angle is controlled by the scale on the upper end of the scale plate 5. Then, the rotating measuring structure is fixed in angle by several slots 6 on the upper end of the positioning plate 4 to prevent angle deviation during operation. Then, the crossbar 1 is placed on the upper surface of the steel structure cutting position. The device is fixed by contacting the upper surface of the steel structure with the carrying and mounting structure. Then, the adjusted rotating measuring structure is in contact with the cutting surface. When the cutting surface is in close contact with the rotating measuring structure, it means that the steel structure cutting angle meets the standard. When the cutting surface and the rotating measuring structure cannot fit together, the rotating measuring structure is separated from the slots 6 on the outside of the positioning plate 4, and the rotating measuring structure is manually fitted to the cutting surface. The position of the scale plate 5 corresponding to the rotating measuring structure is observed to calibrate the cutting angle of the steel structure.

[0026] In some technical solutions, reference Figure 1 The fixed bearing 2 is movably fitted with a rotating measuring structure, which includes a mounting shaft 8, a rotating rod 9, a moving frame 10, a pointer 11, a connecting plate 12, a threaded sleeve 13, a positioning screw 14, and a positioning cone 15.

[0027] One end of the mounting shaft 8 is embedded in the fixed bearing 2. The top end of the rotating rod 9 is fitted onto the upper end of the mounting shaft 8 through the bearing. The movable frame 10 is fixedly installed on the top end of the rotating rod 9. The pointer 11 is fixedly installed on one side inside the movable frame 10. The connecting plate 12 is fixedly installed on the top end of the movable frame 10. The threaded sleeve 13 is fixedly installed on the side wall of the connecting plate 12. The positioning screw 14 is movably embedded in the threaded sleeve 13. The positioning cone 15 is fixedly installed at the bottom end of the positioning screw 14 and is movably embedded in one of the slots 6.

[0028] In this technical solution, when the cutting angle of the steel structure is detected and calibrated, the rotating rod 9 is adjusted to a specified angle under the connection between the connecting shaft and the fixed bearing 2. The angle of the rotating rod 9 is precisely adjusted by the pointer 11 inside the moving frame 10 cooperating with the scale plate 5. Then, the positioning screw 14 inside the threaded sleeve 13 is turned until the positioning cone 15 at the bottom of the positioning screw 14 is embedded in the specified slot 6. Under the connection of the connecting plate 12, the angle of the rotating rod 9 can be accurately positioned.

[0029] In some technical solutions, reference Figure 1 A carrying and mounting structure is installed on one side of the crossbar 1. The carrying and mounting structure includes a mounting plate 16, a magnetic block 17, and a handle 18.

[0030] The mounting plate 16 is bolted to the side wall of the crossbar 1 at both ends, the magnetic block 17 is fixedly installed on the side wall of the mounting plate 16, and the handle 18 is fixedly installed on the top of the mounting plate 16.

[0031] In this technical solution, during measurement, the mounting plate 16 is first fixed to one side of the crossbar 1 with bolts, and the mounting plate 16 is stably placed on the upper end of the steel structure by contacting the magnetic block 17 with the steel structure surface, thereby fixing the device. The device can be quickly picked up and carried by the handle 18.

[0032] In some technical solutions, reference Figure 1 The mounting rod 3 has a positioning groove 19 on its side wall, which can cooperate with the positioning cone 15 to keep the rotating rod 9 parallel to the crossbar 1, reducing the space occupied during carrying. The mounting shaft 8 has a limit nut 20 on both sides to prevent the mounting shaft 8 from moving axially. The top of the positioning screw 14 is equipped with an operating handle 21, which supports flexible operation by a single person at high altitudes or in confined spaces. The positioning plate 4 and the scale plate 5 are both arc-shaped to ensure that the angle scale is clear and visible.
