[0022] 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.

[0023] like Figures 1 to 3 As shown, the embodiment of the utility model provides a welding auxiliary tooling for a steel arch frame and a connecting plate, comprising a base plate 100, a first installation stopper 104 and a second installation stopper 106. Among them, a first positioning plate 102 is arranged on the base plate 100, and the first positioning plate 102 is suitable for limiting the relative position of the connecting plate and the base plate 100; the first installation stopper 104 is installed on the first positioning plate 102, and the first installation stopper 104 is used to abut against the side of the first flange 118 in the steel arch frame to limit the verticality of the first flange 118 and the connecting plate; the second installation stopper 106 is installed on the base plate 100, and the second installation stopper 106 is used to abut against the outer end surface of the second flange 120 in the steel arch frame to limit the verticality of the second flange 120 and the connecting plate.

[0024] According to the auxiliary tooling for welding the steel arch frame and the connecting plate provided by the embodiment of the utility model, by setting the first positioning plate 102, the first installation stopper 104 and the second installation stopper 106, the relative position and verticality of the connecting plate, the first flange 118 and the second flange 120 of the steel arch frame can be accurately defined. This not only ensures the stability during the welding process, but also greatly improves the precision of welding and ensures the welding quality. With this auxiliary tooling, workers do not need to perform cumbersome manual adjustments and positioning, and only need to place the connecting plate and the steel arch frame in the corresponding positions, which greatly simplifies the operation process and improves work efficiency. Since the auxiliary tooling can quickly and accurately complete the positioning of the connecting plate and the steel arch frame, workers can start welding work faster, thereby shortening the time of the entire welding process and improving work efficiency. By ensuring the precision and stability of welding, this auxiliary tooling can avoid engineering quality problems caused by poor welding and ensure the stability and safety of the entire project. The design of this auxiliary tooling has a certain degree of versatility and can be applied to the welding work of steel arch frames and connecting plates of different sizes and specifications, and has strong adaptability.

[0025] Please continue to see Figures 1 to 3 The base plate 100 is the foundation of the entire tooling and is used to carry and fix other components. A first positioning plate 102 is provided on the base plate 100. The position and size of the first positioning plate 102 are precisely designed to ensure that the connecting plate is accurately placed on the base plate 100, thereby defining the relative position of the connecting plate and the base plate 100.

[0026] The first installation stopper 104 is installed on the first positioning plate 102. Its main function is to abut against the side of the first flange 118 in the steel arch. By adjusting the position and angle of the first installation stopper 104, it can be ensured that the first flange 118 and the connecting plate remain vertical, thereby improving the accuracy and quality of welding.

[0027] The second installation stopper 106 is directly installed on the bottom plate 100. Its main function is to abut against the outer end surface of the second flange 120 in the steel arch. Similarly, by adjusting the position and angle of the second installation stopper 106, it can be ensured that the second flange 120 and the connecting plate are also vertical. In this way, the entire steel arch can maintain an accurate relative position and verticality with the connecting plate.

[0028] Through the synergistic effect of the first positioning plate 102, the first installation stopper 104 and the second installation stopper 106, the relative position and verticality between the steel arch frame and the connecting plate can be ensured to achieve extremely high precision. This can not only improve the quality of welding, but also reduce the rework and repair costs caused by poor welding. After using this auxiliary tooling, workers no longer need to perform tedious manual adjustment and positioning work. Just place the connecting plate and the steel arch frame in the corresponding position on the tooling, and then you can start welding. This greatly simplifies the operation process and improves work efficiency.

[0029] Optionally, a second positioning plate 108 is further included. The second positioning plate 108 is installed on the second installation limiter 106. The second positioning plate 108 is used to abut against the side of the second flange 120 to limit the verticality between the second flange 120 and the connecting plate.

[0030] In the further improved embodiment of the utility model, the auxiliary tooling for welding the steel arch frame and the connecting plate includes not only the bottom plate 100, the first installation stopper 104 and the second installation stopper 106, but also a second positioning plate 108. The second positioning plate 108 is cleverly installed on the second installation stopper 106, and its main function is to abut against the side of the second flange 120 in the steel arch frame, thereby further limiting the verticality between the second flange 120 and the connecting plate. By abutting the second positioning plate 108 against the side of the second flange 120, the verticality between the second flange 120 and the connecting plate can be further limited and ensured, thereby greatly improving the accuracy and quality of welding.

[0031] Through the synergistic effect of the first installation stopper 104, the second installation stopper 106 and the second positioning plate 108, the entire welding process is more stable. This helps to reduce errors and fluctuations in the welding process and improve the welding quality. By ensuring accurate welding between the steel arch frame and the connecting plate, the stability and safety of the entire project can be improved. This helps to improve the overall quality of the project and reduce safety hazards and maintenance costs caused by quality problems.

[0032] Optionally, the first positioning plate 102 is suitable for being connected to the base plate 100 via a first sliding structure.

[0033] The first sliding structure allows the first positioning plate 102 to slide horizontally on the bottom plate 100 to accommodate connecting plates of different sizes. When the size of the connecting plate to be welded changes, the worker can easily adjust the position of the first positioning plate 102 to align it with the edge of the connecting plate, thereby ensuring that the connecting plate is accurately placed on the bottom plate 100.

[0034] The introduction of the first sliding structure enables the auxiliary tooling to adapt to more connecting plates of different sizes. Regardless of how the size of the connecting plate changes, the worker can ensure the accuracy and quality of welding by adjusting the position of the first positioning plate 102. Through the first sliding structure, the worker can easily adjust the position of the first positioning plate 102 without using additional tools or equipment. This greatly simplifies the operation process and improves work efficiency.

[0035] Optionally, a locking member is provided between the first positioning plate 102 and the bottom plate 100 , and the first positioning plate 102 is adapted to be locked relative to the bottom plate 100 by the locking member.

[0036] The first sliding structure can also be equipped with a locking mechanism to ensure that the position of the first positioning plate 102 remains stable during the welding process. When the first positioning plate 102 is adjusted to a suitable position, the worker can fix it through the locking mechanism to prevent position deviation caused by external force or vibration during the welding process.

[0037] Optionally, the second mounting stopper 106 includes a mounting plate 110 and an abutment plate 112 , wherein the mounting plate 110 is adapted to be connected to the base plate 100 via a second sliding structure; the abutment plate 112 is vertically mounted on the mounting plate 110 , and the abutment plate 112 is adapted to abut against the outer end surface of the second flange 120 .

[0038] The mounting plate 110 is the base part of the second mounting stopper 106, and is connected to the base plate 100 via a second sliding structure. This design allows the mounting plate 110 to slide horizontally on the base plate 100, thereby adapting to the second flange 120 of the steel arch frame of different sizes or positions. This sliding structure can be equipped with a locking mechanism to ensure that the position of the mounting plate 110 remains stable during the welding process.

[0039] The abutment plate 112 is vertically mounted on the mounting plate 110, and its main function is to abut against the outer end surface of the second flange 120 in the steel arch. The abutment plate 112 should be designed to ensure that there is sufficient contact area between it and the outer end surface of the second flange 120 to provide stable support and limit. Through the close contact between the abutment plate 112 and the second flange 120, the verticality between the second flange 120 and the connecting plate can be ensured, thereby improving the accuracy and quality of welding.

[0040] In the embodiment of the utility model, the second sliding structure can be a combination of a sliding groove and a sliding block. Accordingly, the sliding groove can be provided on the bottom plate 100 , and the sliding block can be provided on the mounting plate 110 .

[0041] Through the synergistic effect of the mounting plate 110 and the abutment plate 112, the second mounting stopper 106 can provide stable support and stop for the second flange 120 of the steel arch. This helps to reduce vibration and displacement during welding and ensure the stability and quality of welding. The design of the second sliding structure allows workers to easily adjust the position of the second mounting stopper 106 without complicated operations or tools. This greatly simplifies the workflow and improves work efficiency.

[0042] Optionally, the second positioning plate 108 is connected to the abutment plate 112 .

[0043] The second positioning plate 108 is connected to the abutment plate 112, and this connection mode can be a fixed connection or an adjustable connection. The fixed connection can ensure that the relative position between the second positioning plate 108 and the abutment plate 112 is fixed, thereby providing a more stable support and limiting effect; while the adjustable connection allows the relative position between the second positioning plate 108 and the abutment plate 112 to be adjusted according to actual needs to adapt to steel arches of different sizes or shapes.

[0044] By connecting the second positioning plate 108 with the abutment plate 112, we can limit the second flange 120 of the steel arch frame from two directions (side and outer end face) at the same time, thereby greatly improving the verticality accuracy between it and the connecting plate. This helps to reduce errors and deformations during welding and improve welding quality. The synergistic effect of the second positioning plate 108 and the abutment plate 112 can provide more stable support for the second flange 120 of the steel arch frame. This stable support helps to reduce vibration and displacement during welding and ensure the stability and safety of the welding process.

[0045] Optionally, the distance between the abutment plate 112 and the center of the base plate 100 is equal to the distance between the center of the base plate 100 and the second flange 120 ; the distance between the edge of the second positioning plate 108 and the center of the base plate 100 is equal to the distance between the center of the base plate 100 and the side of the first flange 118 .

[0046] In the embodiment of the present invention, the positions of the abutment plate 112 and the second positioning plate 108 are precisely designed to ensure that they are consistent with the spacing between the second flange 120 and the first flange 118 of the steel arch.

[0047] First, the abutment plate 112 is designed so that the distance between it and the center of the bottom plate 100 is equal to the distance between the center of the bottom plate 100 and the outer end surface of the second flange 120 of the steel arch. This design ensures that the abutment plate 112 can accurately contact the outer end surface of the second flange 120, thereby effectively limiting the verticality of the second flange 120 and the connecting plate.

[0048] Secondly, the distance between the edge of the second positioning plate 108 and the center of the bottom plate 100 is designed to be equal to the distance between the center of the bottom plate 100 and the side of the first flange 118 of the steel arch. This design enables the second positioning plate 108 to accurately contact the side of the first flange 118, thereby further enhancing the definition of the verticality of the first flange 118.

[0049] By accurately designing the positions of the abutment plate 112 and the second positioning plate 108, the spacing between them and the flanges of the steel arch frame is kept consistent, thereby ensuring high precision during the welding process. This helps to reduce welding errors and improve welding quality. Thus, it can be ensured that the abutment plate 112 limits the second flange 120 of the connecting plate and the second positioning plate 108 limits the first flange 118 of the connecting plate, both of which can form a high positioning accuracy with the center of the steel arch frame.

[0050] Optionally, a base 114 is further included, and the base 114 is disposed on a side of the bottom plate 100 away from the first installation limiter 104 .

[0051] The stability and support capacity of the entire auxiliary tooling can be enhanced by introducing the base 114. The base 114 is designed to be installed on the side of the base plate 100 away from the first mounting stopper 104, that is, below the base plate 100. The introduction of the base 114 is mainly to provide additional support and stability. Due to the vibration and force that may be generated during the welding process, the base 114 can ensure that the entire auxiliary tooling remains stable during operation and avoid displacement or deformation caused by vibration or external force.

[0052] Optionally, at least one of the base 114 and the bottom plate 100 is provided with a weight-reducing hole 116 .

[0053] The design of the weight-reducing holes 116 is to reduce the weight of the entire auxiliary tooling by reducing the use of materials without affecting the structural strength and stability. These holes can be evenly distributed on the base 114 or the bottom plate 100 to ensure uniform stress on the structure.

[0054] The shape, size and number of the weight-reducing holes 116 can be designed according to actual needs. For example, circular, square or other shaped holes can be used, and the size and number of the holes are determined according to the size of the base 114 or the bottom plate 100 and the weight to be reduced.

[0055] Optionally, a roller is provided on the base 114, and a self-locking member is provided on the roller.

[0056] The design of the rollers allows the auxiliary tooling to be easily moved between different work areas. Whether it is a smooth ground or a slightly uneven ground, the rollers can provide stable movement support, greatly reducing the labor intensity of manual handling.

[0057] The introduction of self-locking parts solves the problem of sliding or displacement that may occur during work. When the auxiliary tooling is placed in the predetermined working position, the worker can lock the roller by operating the self-locking parts, thereby ensuring that the auxiliary tooling remains stable during welding or other work processes without unexpected movement or displacement.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
