[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 to Figure 2 As shown, the utility model provides a centering positioning device for a steel arch frame and a connecting plate, comprising a base plate 100 , a clamping member 102 and a positioning member 104 .

[0027] Among them, the base plate 100 is suitable for being installed on the end of the steel arch frame through a connecting piece; the clamping piece 102 is installed on the base plate 100, and the base plate 100 is suitable for being clamped on the side of the steel arch frame through the clamping piece 102; the positioning piece 104 is telescopically arranged on the base plate 100, and the positioning piece 104 is suitable for abutting against the connecting plate to limit the alignment between the connecting plate and the steel arch frame.

[0028] According to the steel arch frame and the connecting plate centering positioning device provided by the embodiment of the utility model, the bottom plate 100 can be quickly and stably installed on the end of the steel arch frame through the connecting piece, which not only simplifies the installation steps, but also improves the installation efficiency. At the same time, the design of the clamping member 102 ensures that the tooling can be firmly fixed on the side of the steel arch frame, thereby maintaining stability during the entire welding process and avoiding the displacement or shaking of the tooling and affecting the welding quality. The retractable design of the positioning member 104 enables the tooling to accurately abut the connecting plate, thereby effectively limiting the centering degree of the connecting plate and the steel arch frame. This high centering degree ensures the accuracy and precision of welding and avoids welding defects caused by insufficient centering degree, such as weld offset, misalignment, etc. Using this auxiliary tooling, workers do not need to spend too much time and energy to adjust the position and angle of the connecting plate, and can complete the centering work by simply operating the tooling, thereby greatly speeding up the welding speed and improving work efficiency. The high stability and centering degree of the tooling reduce the safety risks caused by shaking and misalignment during welding. At the same time, precise alignment of the tooling also helps reduce spatter and smoke during welding, further ensuring worker safety.

[0029] Please continue to see Figure 1 to Figure 2 The bottom plate 100, as the basic part of the welding auxiliary tooling, has sufficient strength and stability. It is designed with suitable mounting holes or connecting grooves so that it can be installed on the end of the steel arch frame through connecting parts (such as bolts, clamps, etc.). The mounting relationship between the bottom plate 100 and the steel arch frame ensures the overall stability of the tooling during the welding process.

[0030] The clamping member 102 is mounted on the bottom plate 100, and can be tightly clamped on the side of the steel arch frame through its adjustable or movable structure. This design ensures a tight connection between the welding auxiliary tooling and the steel arch frame, and avoids welding quality problems caused by tooling movement or shaking during welding. The specific form of the clamping member 102 can be customized according to the shape and size of the steel arch frame to achieve the best clamping effect.

[0031] The positioning member 104 is a component that is telescopically arranged on the base plate 100, and can be adjusted according to the size and position of the connecting plate. One end of the positioning member 104 can abut against the connecting plate, and through its telescopic function, the centering degree between the connecting plate and the steel arch frame can be accurately defined. The telescopic mechanism of the positioning member 104 can be realized by manual adjustment, mechanical drive or electric drive to meet the needs of different working scenarios.

[0032] The welding auxiliary tooling of the utility model can accurately define the centering degree of the connecting plate and the steel arch frame, avoiding quality problems such as weld offset and dislocation caused by inaccurate centering during welding. This greatly improves the accuracy and reliability of welding and ensures the stability and safety of the welded structure.

[0033] According to an embodiment of the present invention, the bottom plate 100 includes an abutment plate 106 and a mounting plate 108. The abutment plate 106 is suitable for overlapping the side portions of the two flanges of the I-beam in the steel arch frame; the mounting plate 108 is vertically mounted on the abutment plate 106, and the positioning member 104 is telescopically mounted on one of the abutment plate 106 and the mounting plate 108.

[0034] The abutment plate 106 is designed to directly overlap the sides of the two flanges of the I-beam in the steel arch. This design allows the base plate 100 to be stably fixed to the steel arch to avoid displacement caused by external forces or vibrations during the welding process. The shape and size of the abutment plate 106 can be customized according to the flange size of the I-beam to ensure good fit and stability.

[0035] The mounting plate 108 is vertically mounted on the abutment plate 106, and provides a mounting surface perpendicular to the surface of the steel arch. This mounting surface is used to mount the clamping member 102 and the positioning member 104, ensuring that they can be firmly fixed on the steel arch without affecting the overall stability of the base plate 100. The design of the mounting plate 108 can also be adjusted as needed to meet different installation requirements.

[0036] By subdividing the bottom plate 100 into the abutment plate 106 and the mounting plate 108, the welding auxiliary tooling of this embodiment can better adapt to the shape and structure of the steel arch frame, and improve the fit and stability between the tooling and the steel arch frame. This helps to reduce welding quality problems caused by the movement or shaking of the tooling during the welding process, and improves the accuracy and reliability of welding.

[0037] The positioning member 104 can be telescopically mounted on one of the abutment plate 106 and the mounting plate 108. In this embodiment, the positioning member 104 can be mounted on the abutment plate 106, and abut the connection plate and limit the degree of alignment between the connection plate and the steel arch frame through the telescopic function. The positioning member 104 can also be mounted on the mounting plate 108, and the height and angle of the positioning member 104 can be adjusted to achieve accurate positioning of the connection plate. Regardless of the installation method, the close contact between the positioning member 104 and the connection plate can be guaranteed to ensure the centering accuracy of the welding.

[0038] According to an embodiment of the present invention, the positioning member 104 includes a fixed portion 109, a telescopic portion 111 and a positioning head 113. The fixed portion 109 is mounted on one of the abutment plate 106 and the mounting plate 108; the telescopic portion 111 is telescopically arranged on the fixed portion 109; and the positioning head 113 is arranged at one end of the telescopic portion 111 away from the fixed portion 109.

[0039] The fixing portion 109 serves as the basis and support of the positioning member 104, ensuring that the positioning member 104 can be stably installed in a fixed position. The fixing portion 109 is installed on one of the abutment plate 106 and the mounting plate 108. This means that the positioning member 104 can be flexibly installed in different parts of the device and positioned according to actual needs.

[0040] The telescopic portion 111 allows the positioning member 104 to be telescopically adjusted within a certain range to meet positioning requirements of different positions or sizes. The telescopic portion 111 should have good telescopic performance and reliability, be able to quickly adjust the length, and remain stable.

[0041] The positioning head 113 is used to directly contact the connection plate to achieve precise positioning. The shape, size and material of the positioning head 113 should be selected according to the characteristics of the object to be positioned to ensure good positioning effect and stability. For example, for an object with a smooth surface, a positioning head 113 with an adsorption function can be used; for an object with a rough surface, a positioning head 113 with a larger contact area can be used.

[0042] According to an embodiment of the present invention, the telescopic portion 111 and the fixed portion 109 are adapted to be locked by a locking member.

[0043] The locking member is used to lock the telescopic part 111 in the desired position to prevent it from sliding or moving during use. The locking member between the telescopic part 111 and the fixed part 109 can ensure that the positioning member 104 can remain stable after being adjusted to the desired position and will not move due to external force or vibration. This greatly improves the centering accuracy of the connecting plate and the steel arch frame during welding and reduces the occurrence of welding defects.

[0044] According to an embodiment of the present invention, the clamping member 102 is fixedly connected to one of the abutting plate 106 and the mounting plate 108 .

[0045] During installation, first fix the clamping member 102 on the abutment plate 106 or the mounting plate 108 to ensure that it is firmly fixed.

[0046] Then, the telescopic portion 111 and the positioning head 113 can be adjusted as needed to accommodate objects of different sizes or shapes.

[0047] After positioning is completed, the telescopic portion 111 can be locked in a desired position by a locking member (such as the bolts, nuts, etc. described above) to ensure positioning accuracy and stability.

[0048] According to an embodiment of the present invention, the clamping member 102 includes a connecting rod 110 and a clamping joint 112. The connecting rod 110 is fixedly connected to one of the abutment plate 106 and the mounting plate 108; the clamping joint 112 is formed at the end of the connecting rod 110 and is arranged at an angle to the connecting rod 110, and the clamping joint 112 is used to clamp the side portions of the two flanges of the I-beam in the steel arch frame.

[0049] The connecting rod 110 is the base part of the clamping member 102, and is responsible for fixing the clamping member 102 as a whole to the abutment plate 106 or the mounting plate 108. One end of the connecting rod 110 is firmly fixed to the abutment plate 106 or the mounting plate 108 by welding, bolt connection or other methods. The length and cross-sectional shape of the connecting rod 110 can be adjusted according to actual application requirements.

[0050] The clamping joint 112 is a key part of the clamping member 102. Its shape and size are designed to fit tightly with the sides of the two flanges of the I-beam to achieve a clamping effect. The clamping joint 112 is formed at the end of the connecting rod 110 and is arranged at a certain angle to the connecting rod 110. This angle is designed to adapt to the shape of the flange of the I-beam to ensure that the clamping joint 112 can fit tightly on the side of the flange. The shape of the clamping joint 112 can be customized according to the flange size of the I-beam to achieve a better clamping effect.

[0051] The design of the clamping member 102 can ensure a stable connection between the welding auxiliary tooling and the steel arch. The clamping joint 112 fits tightly against the flange side of the I-beam, reducing the possibility of the tooling moving or loosening due to external force or vibration, thereby improving the stability of the welding process. The clamping joint 112 can be customized according to the flange size of the I-beam, so that the welding auxiliary tooling can adapt to steel arches of different specifications and models. This design enhances the applicability and flexibility of the tooling.

[0052] According to one embodiment of the present invention, the connecting member includes a screw rod 114 and a first nut 116. The screw rod 114 is connected to one side of the mounting plate 108 facing the end of the steel arch; the first nut 116 is connected to the screw rod 114 and is located between the mounting plate 108 and the end of the steel arch.

[0053] The screw rod 114 is the main component of the connector, which is responsible for connecting the mounting plate 108 to the steel arch. One end of the screw rod 114 is connected to the side of the mounting plate 108 facing the end of the steel arch. This side may be a specially designed hole or threaded hole of the mounting plate 108 for receiving the screw rod 114.

[0054] The first nut 116 is used in conjunction with the screw rod 114, and a pre-tightening force is generated by tightening the nut, thereby ensuring a firm connection between the mounting plate 108 and the steel arch. The first nut 116 is located between the mounting plate 108 and the end of the steel arch, and is sleeved on the screw rod 114. When the nut is tightened, it applies pressure to the mounting plate 108, so that the mounting plate 108 fits tightly against the surface of the steel arch.

[0055] The design of the connector is simple and intuitive, and does not require complicated installation steps or tools, making the installation process more convenient and quick. The pre-tightening force generated by tightening the first nut 116 can ensure that the connection between the mounting plate 108 and the steel arch is firm and reliable, and is not easy to loosen or fall off.

[0056] According to an embodiment of the present invention, there are at least two groups of connecting members, and at least two groups of connecting members are arranged on the bottom plate 100 at intervals.

[0057] By setting at least two groups of connectors at intervals, the number and dispersion of connection points are increased, thereby improving the stability and safety of the entire structure. This helps to resist external loads and vibrations and reduce the risk of structural deformation and damage. Since the connectors can be set in multiple groups and distributed at intervals on the base plate 100, the position and number of connection points can be adjusted according to actual needs. This makes the design more flexible and adaptable, and can adapt to steel arches or other supporting structures of different specifications and shapes.

[0058] According to an embodiment of the present invention, the connector further comprises a second nut 118. When the screw rod 114 is passed through the end of the steel arch frame, the second nut 118 is suitable for being installed on the segment where the screw rod 114 passes through the end of the steel arch frame.

[0059] The second nut 118 is located at the end of the screw rod 114 passing through the steel arch frame, and also generates a pre-tightening force by tightening, thereby enhancing the connection strength between the connecting piece and the steel arch frame. The installation of the second nut 118 ensures the stable fixation of the screw rod 114 inside the steel arch frame, further improving the stability and safety of the structure.

[0060] The connection strength between the connecting member and the steel arch is significantly enhanced by adding the second nut 118. The second nut 118 ensures that the screw rod 114 is stably fixed inside the steel arch, reducing the risk of loosening or falling off.

[0061] According to an embodiment of the present invention, the screw rod 114 is welded to the mounting plate 108 .

[0062] The structure in which the screw rod 114 is welded to the mounting plate 108 in this embodiment may be applicable to various scenarios requiring high-strength and high-stability connections. In this embodiment, the screw rod 114 is connected to the mounting plate 108 by welding, thereby achieving a high-strength and high-stability connection effect. This connection method is not only simple to operate and low in cost, but also can ensure the quality of the connection.
