Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding auxiliary frame technology, specifically to a steel plate welding auxiliary frame. Background Technology
[0002] In modern industrial production, steel plate welding is widely used in the manufacture of various metal structural components, such as bridge construction, automobile manufacturing, and shipbuilding. The quality of welding directly affects the performance and service life of the product, and welding auxiliary equipment plays a crucial role in ensuring welding quality and improving welding efficiency.
[0003] Currently, most steel plate welding support frames on the market are fixed structures. While these structures provide some support and stability for routine horizontal or vertical welding tasks, their limitations become apparent when dealing with special welding requirements such as diagonal welding and inclined butt welding. Because the angle of the welding frame is difficult to adjust flexibly, operators often need to use additional tools or complex manual operations to change the placement angle of the steel plate. This process is not only time-consuming and labor-intensive, but also makes it difficult to ensure precise positioning of the steel plate during adjustment, easily leading to welding position deviations. Once a deviation occurs, it not only affects the strength and aesthetics of the weld joint, but in severe cases, it can even lead to the scrapping of the entire weldment, significantly increasing production and time costs. Utility Model Content
[0004] The purpose of this utility model is to provide a steel plate welding auxiliary frame to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel plate welding auxiliary frame, comprising a base A and a base B, wherein the adjacent ends of the base A and the base B are rotatably connected, and a crossbeam is fixedly installed on the lower surface of the far end of the base A and the base B. A caster wheel A is installed on the lower surface of the front and rear ends of the crossbeam, and a caster wheel B is installed on the lower surface of the adjacent ends of the base A and the base B. A U-shaped carrier frame with adjustable position is installed inside the base A and the base B. A clamping mechanism is installed inside the U-shaped carrier frame, and a positioning mechanism is installed on the front right end of the base A.
[0006] Preferably, both base A and base B are fixedly installed with slide rails, and the lower surface of the U-shaped carrier is provided with slide grooves. The U-shaped carrier is slidably connected to the corresponding slide grooves. Both base A and base B are rotatably installed with threaded rods, and the threaded rods are threadedly connected to the corresponding U-shaped carriers.
[0007] Preferably, the clamping mechanism includes a screw, which is threaded through and screwed into the U-shaped carrier, and a pressure block is fixedly installed on the rear surface of the screw, and a handwheel is fixedly installed on the front surface of the screw.
[0008] Preferably, a transition groove is provided through the upper right end of the base A, and a transition post is fixedly installed on the upper left end of the base B, with the transition post rotatably installed in the transition groove.
[0009] Preferably, the upper right surface of the base A is provided with an angle mark in a circumferential direction, and the upper surface of the adapter post is provided with a slot, in which an L-shaped reading finger block is inserted and installed.
[0010] Preferably, the positioning mechanism includes a nut, which is fixedly installed on the front surface of the base A, and a bolt is screwed into the nut. The rear surface of the bolt penetrates the base A and fits against the outer surface of the adapter column, and an operating rod is fixedly installed on the front surface of the bolt.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] I. This utility model achieves this by rotatably connecting the proximal ends of base A and base B, and by providing sliding U-shaped carriers on both base A and base B. In practical applications, operators can easily place the two steel plates to be welded into the U-shaped carriers. Depending on the welding conditions, the angle between base A and base B can be quickly adjusted to precisely adjust the welding angle, subsequently enabling the butt welding of the two steel plates. The entire process requires no complex procedures or additional auxiliary tools, significantly reducing the time needed for angle adjustment, lessening the operator's workload, and improving work efficiency.
[0013] II. This utility model features an angle marker on the upper right surface of base A and an L-shaped reading indicator inserted into the upper surface of the adapter post. The L-shaped reading indicator rotates synchronously with the adjustment of base B, accurately pointing to the angle marker. This design provides a clear angle reference for operators during welding angle adjustment, reducing the impact of human factors on angle adjustment, improving the accuracy and stability of welding angle adjustment, thereby ensuring welding quality and reducing scrap rates.

Detailed Implementation
[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides a technical solution:
[0023] To achieve the above objectives, this utility model provides the following technical solution: a steel plate welding auxiliary frame, including a base A1 and a base B2, with the adjacent ends of the base A1 and base B2 rotatably connected, and a crossbeam 3 fixedly installed on the lower surface of the far end of the base A1 and base B2. Universal wheels A31 are installed on the lower surfaces of the front and rear ends of the crossbeam 3. Universal wheels B4 are installed on the lower surfaces of the adjacent ends of the base A1 and base B2. A U-shaped carrier 5 with adjustable position is installed inside the base A1 and base B2. A clamping mechanism 6 is installed inside the U-shaped carrier 5. A positioning mechanism 9 is installed on the front right end of the base A1. The positioning mechanism 9 is used to lock and fix the transition position of the base A1 and base B2.
[0024] It should be noted that, as Figure 4 As shown, slide rails 7 are fixedly installed inside base A1 and base B2. Slide grooves 51 are opened on the lower surface of the U-shaped frame 5. The U-shaped frame 5 is slidably connected to the corresponding slide groove 51. Threaded rods 8 are rotatably installed inside base A1 and base B2. Threaded rods 8 are threadedly connected to the corresponding U-shaped frame 5. A crank handle is fixedly installed on the outer end of the threaded rod 8. By cranking the crank handle, the threaded rod 8 is rotated, thereby using the threaded rod 8 to drive the corresponding U-shaped frame 5 to slide left and right on the slide rail 7.
[0025] When actually operating this welding auxiliary frame, it is necessary to refer to... Figure 5 or Figure 6 The two steel plates to be welded are placed in two U-shaped carriers 5 respectively. The clamping mechanism 6 in each U-shaped carrier 5 is used to firmly clamp the steel plates. Then, according to the specific welding angle requirements, the docking angle of the two steel plates is flexibly changed by rotating the base B2. After adjusting to the appropriate position, the threaded rod 8 is used to drive the corresponding U-shaped carrier 5 to move in the docking direction of the steel plates, thereby realizing the docking of the two steel plates. Then, the positioning mechanism 9 is used to firmly lock the transition end of the base A1 and the base B2 to ensure that the two steel plates remain stable and fixed in the docked position, and then the welding work can be carried out.
[0026] Compared with existing technologies, this welding auxiliary frame allows operators to quickly adjust the welding angle according to different welding conditions in actual use, without the need for complicated operations and additional auxiliary tools, greatly saving time and effort in angle adjustment and significantly improving work efficiency.
[0027] like Figure 3 As shown, the clamping mechanism 6 includes a screw 61, which is threaded through and screwed into the U-shaped carrier 5. A pressure block 62 is fixedly installed on the rear surface of the screw 61, and a handwheel 63 is fixedly installed on the front surface of the screw 61. After the steel plate is placed into the corresponding U-shaped carrier 5, the handwheel 63 can be manually rotated to drive the screw 61 to rotate, thereby driving the pressure block 62 to move towards the steel plate. The pressure block 62 is used to clamp and fix the steel plate in the U-shaped carrier 5.
[0028] like Figure 4 As shown, a connecting groove 11 is provided through the upper right end of the base A1, and a connecting post 21 is fixedly installed on the upper left end of the base B2. The connecting post 21 is rotatably installed in the connecting groove 11. The rotatable connection between the base A1 and the base B2 is achieved through the installation and cooperation of the connecting post 21 and the connecting groove 11.
[0029] Combination Figure 4 and Figure 2 As shown, the upper right surface of the base A1 is circumferentially marked with angle indicators, and the upper surface of the adapter post 21 is provided with a slot 211. An L-shaped reading finger block 22 is inserted into the slot 211. By setting the angle indicators and the L-shaped reading finger block 22, the angle between the base B2 and the base A1 can be intuitively displayed during the adjustment of the welding angle. This provides the operator with a clear angle reference during the welding angle adjustment operation, reduces the influence of human factors on the angle adjustment, improves the accuracy and stability of the welding angle adjustment, thereby ensuring welding quality and reducing the scrap rate.
[0030] Finally, as Figure 2As shown, the positioning mechanism 9 includes a nut 91, which is fixedly installed on the front surface of the base A1. A bolt 92 is screwed into the nut 91. The rear surface of the bolt 92 penetrates the base A1 and fits against the outer surface of the adapter post 21. An operating rod 93 is fixedly installed on the front surface of the bolt 92. By manually adjusting the operating rod 93, the bolt 92 can be rotated, so that its rear end is pressed against or separated from the adapter post 21, thereby fixing or unlocking the adapter end of the base A1 and the base B2.
