Description

Technical Field

[0001] This application relates to the field of clamping technology, and in particular to a fixing clamp based on billboard manufacturing. Background Technology

[0002] Billboards are large panels used to display advertisements and other information, typically installed in high-traffic areas such as city centers, highways, airports, and train stations. The frame of a billboard is generally formed by welding together multiple steel or aluminum alloy tubing, which is usually secured using clamps to facilitate welding.

[0003] A search revealed that Chinese Patent CN221967163U discloses a fixing fixture based on billboard manufacturing, which welds both sides of the frame using a mobile welding device. However, this device is only suitable for prefabricated frames. For frames formed by welding multiple pipes, it is inconvenient to fix the pipes, affecting the welding effect. The traditional method is for workers to fix the pipes by hand for welding, resulting in low welding accuracy. In addition, Chinese Patent CN211991557U discloses a frame welding fixture, which uses corner fasteners to position the pipes of the frame and then fixes the pipes with pipe fixing components, improving welding accuracy. However, when welding the other side of the joint, this device requires removing the frame and fixing it before welding, which is more complicated and affects welding efficiency. Therefore, a fixing fixture based on billboard manufacturing is proposed to solve the above problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-5 This utility model provides a fixing clamp based on billboard manufacturing, used to clamp and fix the pipes during frame welding in the billboard manufacturing process, and has the effect of rapid double-sided welding. Technical solution:

[0026] A fixing clamp based on billboard manufacturing includes a pole 1, a crossbar 2 fixedly connected to the front side of the pole 1, a support arm 3 vertically fixedly connected to the end of the crossbar 2, a first fixing member 4 fixedly connected to the upper and lower ends of the support arm 3, a second fixing member 5 slidably arranged on the pole 1 along the height direction, the second fixing member 5 moves closer to the first fixing member 4 to clamp and fix the pipe 6 located between the two, and welding joints 8 for the exposed connection seam 7 are formed on the front and rear sides of the first fixing member 4 and the second fixing member 5.

[0027] Specifically, by setting the second fixing member 5, it can move closer to the first fixing member 4. The two work together to clamp and fix the pipe 6, preventing the pipe 6 from shifting and ensuring the welding accuracy. By setting the welding joint 8 formed by the first fixing member 4 and the second fixing member 5, it is convenient for the user to weld the exposed connecting seam 7 from the front and the back respectively. Compared with the existing technology, there is no need to remove the frame from the fixing fixture and then fix it, which improves the welding efficiency.

[0028] The first fastener 4 is rectangular in shape, and a notch wall 401 is formed at the corner where the first fastener 4 and the connecting seam 7 are directly opposite. The second fastener 5 is inverted L-shaped so that a weld joint 8 is formed between the first fastener 4 and the second fastener 5.

[0029] The second fixing member 5 has a horizontal arm 501 and a vertical arm 502 that are fixed vertically. The bottom of the horizontal arm 501 is provided with a second horizontal limiting groove 503, and the side of the vertical arm 502 near the pipe 6 is provided with a second vertical limiting groove 504.

[0030] The top of the first fixing member 4 is provided with a first horizontal limiting groove 402, and the side of the first fixing member 4 near the vertical arm 502 is provided with a first vertical limiting groove 403. The first horizontal limiting groove 402, the horizontal arm 501, and the second horizontal limiting groove 503 are used to fix the horizontally placed pipe 6, and the first vertical limiting groove 403, the vertical arm 502, and the second vertical limiting groove 504 are used to fix the vertically placed pipe 6, thereby improving the welding accuracy. The dimensions of the first fixing member 4 and the second fixing member 5 can be determined as needed. The distance between the first vertical limiting groove 403 and the second vertical groove on the same side is adapted to the width of the pipe 6.

[0031] An allowance opening 505 is provided at the joint of the horizontal arm 501 and the vertical arm 502. The allowance opening 505 exposes the apex of the connecting seam 7. By providing the allowance opening 505, it is convenient for workers to weld the apex of the connecting seam 7.

[0032] The back of the two upper second fixing members 5 and the back of the two lower second fixing members 5 are fixedly connected with U-shaped connecting arms 9. The middle of the connecting arm 9 is fixedly connected with a slider 10. The back of the upright 1 is provided with a sliding groove 101, and the slider 10 is slidably connected to the sliding groove 101.

[0033] The inner bottom wall of the slide 101 is rotatably connected to a bidirectional threaded screw 11. The top of the slider 10 is provided with a threaded hole. The slider 10 is threadedly connected to the bidirectional threaded screw 11 through the threaded hole. The two sliders 10 are symmetrically arranged on the two helical sections of the bidirectional threaded screw 11. The top end of the bidirectional threaded screw 11 passes through the top of the upright 1 and is fixedly connected to a handwheel 12. By rotating the handwheel 12, the bidirectional threaded screw 11 is driven to rotate, which in turn drives the two sliders 10 to move closer to each other, which in turn drives the two connecting arms 9 to move closer to each other, which in turn drives the upper second fixing member 5 to move closer to the lower fixing member, thus fixing the pipe 6. In other embodiments, a motor can also be used to drive the bidirectional threaded screw 11.

[0034] A counterweight base 13 is fixedly connected to the bottom of the upright 1. The stability of the device is improved by setting the counterweight base 13.

[0035] Working principle: When this billboard-based fixing clamp is used, initially, the first fixing member 4 and the second fixing member 5 are far apart. The user first places one pipe 6 on the upper first horizontal limiting groove 402, and the second pipe 6 on the lower second horizontal limiting groove 503. Then, the third and fourth pipes 6 are respectively placed into the first vertical limiting grooves 403 on both sides, with their bottoms supported by the lower horizontal arm 501. Then, the handwheel 12 is turned, which drives the bidirectional threaded screw 11 to rotate. The bidirectional threaded screw 11 drives the two sliders 10 to move closer together, and the two sliders 10 drive the two connecting arms 9 to move closer together. The connecting arm 9 drives the upper second fixing member 5 and the lower second fixing member 5 to move towards each other until the first horizontal limiting groove 402 and the second horizontal limiting groove 503 cooperate to fix the horizontally placed pipe 6 and then stop the rotation of the handwheel 12. During this process, the second vertical limiting groove 504 gradually moves to a position directly opposite the first vertical limiting groove 403 to fix the vertically placed pipe 6, prevent the pipe 6 from shifting, and ensure the welding accuracy. The welding joint 8 formed by the first fixing member 4 and the second fixing member 5 makes it easy for the user to weld the exposed connecting seam 7 from the front and the back respectively. Compared with the existing technology, there is no need to disassemble and fix the frame from the fixing fixture, which improves the welding efficiency.
