Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, specifically relating to a flat welding tooling for facilitating welding of wire mesh fence heads. Background Technology

[0002] Wire mesh fencing, also known as fencing or protective netting, is a widely used isolation and protection facility commonly found in various locations such as roads, railways, airports, bridges, factories, residential areas, stadiums, and green spaces. It serves important functions such as separating spaces, ensuring safety, and beautifying the environment, making it a key facility for maintaining order and security in public places.

[0003] In the wire mesh fence manufacturing process, precisely aligning and welding the fence head is an indispensable and crucial step. However, most current fixtures on the market rely primarily on manual operation when fixing the fence. Workers must rotate the baffles one by one to align with the fixture. Then, they manually push the fence away from the head, causing the fence head to move and align with the baffles. Alignment is achieved through the baffles' limiting mechanism, and then the baffles are removed, allowing welding equipment to weld the fence head. This purely manual operation mode has significant drawbacks: for example, the process is cumbersome and time-consuming, greatly slowing down the overall production progress and severely reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a flat welding fixture for facilitating the welding of wire mesh fence heads. This addresses the problem that most existing fixtures on the market rely heavily on manual operation when fixing the wire mesh fence. Workers must rotate each baffle to align with the fixture, then manually push the end of the fence away from the head, causing the fence head to move and align with the baffle. Alignment is achieved through the baffle's limiting mechanism, and then the baffle is removed, allowing welding equipment to weld the fence head. This purely manual operation mode has significant drawbacks: for example, the process is cumbersome and time-consuming, greatly slowing down the overall production progress and severely reducing production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flat welding fixture for facilitating welding of the head of a wire mesh fence, comprising a frame and a support frame connected inside the frame. Fixing blocks are installed at both ends of the frame by bolts. A baffle is rotatably connected to the side wall of the fixing block via a rotating shaft. An installation rod is provided at the bottom end of the baffle. A connecting rod is connected to the end of the installation rod. A rectangular block is connected to the end of the connecting rod. The baffle includes a first part, a second part, and a third part.

[0006] As a preferred flat welding fixture for facilitating welding of the head of the fence according to this utility model, the bottom end of the third part is provided with an opening that matches the position of the support frame, the first part is rotatably connected to the surface of the rotating shaft, and the connection between the first part and the second part is arc-shaped.

[0007] As a preferred embodiment of the flat welding fixture for facilitating welding of the head of the fence according to this utility model, the mounting rod is connected to the first part of the baffle, and the mounting rod can be rotatably connected to the fixing block through a rotating shaft.

[0008] As a preferred embodiment of the present invention, a flat welding fixture for facilitating welding of the head of a wire mesh fence is provided, wherein a mounting bracket is connected to the bottom end of the frame, a recessed block is connected to the top of the recessed bracket, a mating block is rotatably connected inside the recessed block, and a cylinder is installed at the top of the mating block.

[0009] As a preferred flat welding fixture for facilitating welding of the head of a wire mesh fence according to this utility model, the cylinder can be rotatably connected to the concave block through a docking block.

[0010] As a preferred embodiment of the flat welding fixture for facilitating welding of the head of a wire mesh fence according to this utility model, the telescopic end of the cylinder is connected to an installation block, the top of the installation block is connected to a support block, and the inside of the support block is rotatably connected to a connecting block.

[0011] As a preferred embodiment of the flat welding fixture for facilitating welding of the head of a wire mesh fence according to this utility model, the connecting block and the rectangular block are connected, and the rectangular block can be rotatably connected to the support block through the connecting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Through the coordinated action of the baffle and the fixing block, the baffle can be securely fastened to the support frame. Thus, when the fence is placed within the opening in the support frame, simply pushing the end of the fence furthest from the head towards the baffle easily aligns the fence head, significantly improving alignment efficiency. Following this, the installation rod, connecting rod, rectangular block, recessed block, mating block, cylinder, mounting block, support block, and connecting block successfully realize a multi-link linkage mechanism.

[0020] 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.

[0021] Please see Figures 1-4 The present invention provides the following technical solution: a flat welding fixture for facilitating welding of the head of a wire mesh fence, comprising a frame 1 and a support frame 2 connected inside the frame 1. Fixing blocks 3 are installed at both ends of the frame 1 by bolts. A baffle 4 is rotatably connected to the side wall of the fixing block 3 by a rotating shaft. An installation rod 5 is provided at the bottom end of the baffle 4. A connecting rod 6 is connected to the end of the installation rod 5. A rectangular block 14 is connected to the end of the connecting rod 6. The baffle 4 includes a first part 41, a second part 42 and a third part 43.

[0022] In practical use, when the wire mesh is placed in the opening provided by the support frame 2, simply push the wire mesh close to the baffle 4, and then make it contact the third part 43 of the baffle 4, so that the head of the wire mesh can be easily aligned, which significantly improves the alignment efficiency.

[0023] Preferably, the bottom end of the third part 43 has an opening that matches the position of the support 2. The first part 41 is rotatably connected to the surface of the rotating shaft. The connection between the first part 41 and the second part 42 is arc-shaped. The mounting rod 5 is connected to the first part 41 of the baffle 4. The mounting rod 5 can be rotatably connected to the fixing block 3 through the rotating shaft. The bottom end of the frame 1 is connected to the mounting bracket 7. The top end of the recess of the mounting bracket 7 is connected to the recess 8. The inside of the recess 8 is rotatably connected to the docking block 9. The top end of the docking block 9 is equipped with a cylinder 10. The cylinder 10 can be rotatably connected to the recess 8 through the docking block 9. The telescopic end of the cylinder 10 is connected to the mounting block 11. The top end of the mounting block 11 is connected to the support block 12. The inside of the support block 12 is rotatably connected to the connecting block 13. The connecting block 13 is connected to the rectangular block 14. The rectangular block 14 can be rotatably connected to the support block 12 through the connecting block 13.

[0024] In practical use, during the rotation of the baffle 4, the pre-drilled notch at the bottom of its third part 43 can precisely fit and connect with the support frame 2. When the fence is placed at the opening of the support frame 2, the baffle 4 and the support frame 2 work together to effectively prevent the fence from accidentally passing through the bottom of the baffle 4 when it is pushed because the baffle 4 is directly attached to the support frame 2.

[0025] When the baffle 4 opens and closes, its first part 41 can rotate flexibly around the pivot. This design greatly facilitates the separation and engagement of the third part 43 and the support frame 2, ensuring the smoothness of the entire process. At the same time, the connection between the first part 41 and the second part 42 of the baffle 4 is an arc-shaped design. During the opening and closing of the baffle 4, the second part 42 can naturally fit against the top surface of the frame 1, which not only optimizes the compactness of the overall structure but also ensures good fit between components.

[0026] From the perspective of the linkage structure, since the mounting rod 5 is firmly connected to the first part 41 of the baffle 4, and the baffle 4 is rotatably connected to the fixed block 3 via a rotating shaft, it lays the foundation for a series of subsequent linkage operations. The mounting bracket 7 provides stable fixed support for the recessed block 8, while the docking block 9 rotatably connected inside the recessed block 8 facilitates the assembly of the cylinder 10. When the cylinder 10 starts working, it can flexibly adjust its angle by means of the rotatable connection between the docking block 9 and the recessed block 8, avoiding the impact of angle limitations on the coordinated cooperation between the rectangular block 14, the mounting rod 5, and the connecting rod 6. In addition, the mounting block 11 facilitates the assembly of the support block 12, and the connecting block 13 and the rectangular block 14 also achieve efficient connection and cooperation. In this way, when the cylinder 10 works, the various components work together to successfully realize the multi-link linkage mechanism, enabling the opening and closing operation of the baffle 4 to be fully automated, significantly improving operating efficiency and automation.

[0027] Working principle: When making the fence, the fence is placed manually into the opening of the support frame 2. By gently pushing the fence to bring it close to the baffle 4 and make it contact the third part 43 of the baffle 4, the head of the fence can be easily and accurately aligned. This process greatly improves the alignment efficiency.

[0028] When it is necessary to open the baffle 4, first connect the cylinder 10 to the air pump and start the air pump to make the cylinder 10 work. The telescopic end of the cylinder 10 extends, driving the mounting block 11 to move upward. The rise of the mounting block 11 will synchronously drive the connecting block 13 to rise, and the connecting block 13 is connected to the rectangular block 14, thereby driving the rectangular block 14 to rise. The upward movement of the rectangular block 14 will further drive the connecting rod 6 and the mounting rod 5 to rotate. Since the mounting rod 5 is connected to the baffle 4, the baffle 4 will rotate along the pivot, ultimately realizing the rotation and opening of the baffle 4. While the baffle 4 is open, the head of the fence is welded by welding equipment. When it is necessary to close the baffle 4, the telescopic end of the cylinder 10 retracts, the above movement process is reversed, and the baffle 4 closes accordingly, thus realizing the multi-link linkage mechanism.

[0029] Of particular note is that cylinder 10 is rotatably connected to concave block 8 via docking block 9. Throughout the entire linkage process, when the positions of various components change, cylinder 10 can flexibly adjust its angle based on this rotatable connection, avoiding the problem of mutual constraint caused by the fixed lengths of rectangular block 14, connecting rod 6, and mounting rod 5 during movement, which would prevent normal linkage. This ensures the stable and smooth operation of the multi-link linkage system, providing a solid guarantee for the efficient and automated operation of wire mesh fence production. It effectively avoids the drawbacks of cumbersome and time-consuming steps in traditional operations, significantly improving the overall production progress and efficiency.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
