Description

Technical Field

[0001] This utility model relates to the field of steel processing auxiliary tools, and in particular to a steel welding and fixing auxiliary device. Background Technology

[0002] During the fabrication of steel reinforcement cages, it is often necessary to weld "U"-shaped positioning bars to the main reinforcement bars to ensure the structural dimensions and stability of the cage. Before welding, the positioning bars need to be pre-fixed in the accurate positions of the main reinforcement bars. Traditional manual support or simple clamp fixing methods are prone to causing the positioning bars to shift or tilt during welding, affecting the welding quality and the overall accuracy of the steel reinforcement cage. Furthermore, these methods are cumbersome and inefficient. Therefore, there is an urgent need for a device that can conveniently, accurately, and stably fix the positioning bars to the main reinforcement bars to assist in welding. Utility Model Content

[0003] The purpose of this utility model is to provide a steel welding fixing auxiliary device to solve the problems in the prior art of positioning steel bars being inconvenient to fix before welding, being prone to displacement, and affecting welding accuracy.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a steel welding and fixing auxiliary device, the steel welding and fixing auxiliary device comprising: The main body plate has a first sliding groove on its lower surface and a second sliding groove on its upper surface. The first clamping and fixing part is disposed at the lower end of the main body plate. The first clamping and fixing part includes a first adjusting screw and two first clamping plates. The first clamping plates are slidably disposed in the first sliding groove of the main body plate. The left and right sections of the first adjusting screw are respectively provided with threads of the same pitch but opposite directions. The two first clamping plates are respectively engaged with the threads of the left and right sections of the first adjusting screw. The second clamping and fixing part is disposed at the upper end of the main body plate. The second clamping and fixing part includes a second adjusting screw and two second clamping plates. The second clamping plates are slidably disposed in the second sliding groove of the main body plate. The left and right sections of the second adjusting screw are respectively provided with threads of the same pitch but opposite directions. The two second clamping plates are respectively engaged with the threads of the left and right sections of the second adjusting screw. The length of the second clamping plate is greater than the length of the top horizontal section of the "U"-shaped positioning steel bar. The two first clamping plates and the two second clamping plates are symmetrically distributed on both sides of the main body plate.

[0005] In one embodiment, the end of the first adjusting screw is provided with a first locking handle, and the end of the second adjusting screw is provided with a second locking handle.

[0006] In one embodiment, the clamping surface of the first clamping plate has a concave arc-shaped structure.

[0007] In one embodiment, the arc-shaped clamping surface of the first clamping plate is provided with an anti-slip texture.

[0008] In one embodiment, the main body plate, the first clamping and fixing part, and the second clamping and fixing part are all made of steel.

[0009] The above-described technical solutions in the embodiments of this utility model have at least the following technical effects or advantages: The steel welding fixing auxiliary device provided in this embodiment of the invention uses a first clamping and fixing part to stably fix the device to the main reinforcement, and then uses a second clamping and fixing part to fix the positioning reinforcement to be welded. Because the adjusting screw adopts a thread design with opposite rotation directions, it can ensure that the two clamping plates move synchronously in opposite directions, thereby aligning the center lines of the main reinforcement and the positioning reinforcement with the center line of the main plate, ensuring accurate positioning and effectively avoiding offset and tilting before welding. Furthermore, the length design of the second clamping plate effectively prevents the positioning reinforcement from rotating after fixing (the second clamping plate can clamp the top horizontal section and part of the arc-shaped corner section of the positioning reinforcement, preventing the positioning reinforcement from rotating or shifting along its top horizontal section after clamping and fixing). After the entire device is fixed, the welding area of ​​the reinforcement remains exposed, not affecting the welding operation, significantly improving the welding accuracy and efficiency.

[0017] Please refer to Figures 1 to 4 , the embodiment of the present application provides a steel welding fixing auxiliary device, which is used to accurately fix the positioning steel bar 4 on the main steel bar 5 of the steel reinforcement cage in advance when welding the "U-shaped" positioning steel bar 4 on the main steel bar 5, so as to facilitate the welding operation. The device includes: a main body plate 1, a first clamping and fixing part 2 and a second clamping and fixing part 3.

[0018] The main body plate 1 is the base of the entire device. A first groove is provided on its lower surface for mounting the first clamping and fixing part 2, and a second groove is provided on its upper surface for mounting the second clamping and fixing part 3.

[0019] The first clamping and fixing part 2 is used to clamp and fix the main rib 5. It is installed at the lower end of the main body plate 1 and consists of a first adjusting screw 21 and two first clamping plates 22. The two first clamping plates 22 are symmetrically slidably installed in the first sliding groove. The left and right sections of the first adjusting screw 21 are engraved with threads of the same pitch but opposite directions, and respectively mate with the threaded holes of the two first clamping plates 22.

[0020] The second clamping and fixing part 3 is used to clamp and fix the "U"-shaped positioning rebar 4. It is installed on the upper end of the main body plate 1 and has a similar structure to the first clamping and fixing part 2, consisting of a second adjusting screw 31 and two second clamping plates 32. The two second clamping plates 32 are symmetrically slidably installed in the second slide groove and are engaged with the second adjusting screw 31, which has opposite spiral threads, by means of threads. Preferably, the length of the second clamping plate 32 is designed to be greater than the length of the horizontal section at the top of the "U"-shaped positioning rebar 4, so that it can clamp both the horizontal section and the arc-shaped corner parts on both sides at the same time, to prevent the positioning rebar 4 from rotating and shifting around its axis after being fixed.

[0021] In one embodiment, to facilitate the operator in applying torque to lock or release the clamping part, a first locking handle 23 is provided at the end of the first adjusting screw 21, and a second locking handle 33 is provided at the end of the second adjusting screw 31.

[0022] In one embodiment, to enhance the clamping stability of the circular main rib 5, the clamping surface of the first clamping plate 22 facing the main rib 5 is designed as a concave arc structure. This design increases the contact area between the clamping plate and the main rib 5, thereby improving the clamping stability.

[0023] To further improve the reliability of clamping, anti-slip texture 221 can be provided on the arc-shaped clamping surface of the first clamping plate 22. Its principle is similar to the toothed structure on the jaw of a pipe wrench, which can effectively prevent the main rib 5 from slipping during clamping.

[0024] To ensure the overall strength, durability and stability of the device, the main body plate 1, the first clamping and fixing part 2 and the second clamping and fixing part 3 in this embodiment are all made of steel.

[0025] The method of using this device is as follows: First, place the device on the main rib 5, with the two first clamping plates 22 positioned on either side of the main rib 5. Rotate the first locking handle 23 to drive the first adjusting screw 21. Due to the opposite directions of its left and right threads, the two first clamping plates 22 will move synchronously towards the center until the main rib 5 is securely clamped. At this point, the entire auxiliary device is stably fixed to the main rib 5.

[0026] Next, the "U"-shaped positioning steel bar 4 is placed between the two second clamping plates 32, and its position is adjusted along the axial direction of the main bar 5 so that it is aligned with the predetermined welding point.

[0027] Then, rotate the second locking handle 33 to drive the second adjusting screw 31, so that the two second clamping plates 32 move synchronously towards each other and clamp the positioning steel bar 4.

[0028] After fixing, the relative positions of the positioning rebar 4 and the main rebar 5 are precisely fixed (e.g., Figure 3 , Figure 4 As shown in the figure, the centerlines of both are aligned with the centerline of the main plate 1, ensuring the accuracy of the welding. At the same time, the contact point (i.e., welding area 41) between the positioning steel bar 4 and the main steel bar 5 is fully exposed, facilitating the welding operation.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
