Description

Technical Field

[0001] This utility model relates to the field of laser welding auxiliary device technology, specifically a clamping structure for laser welding. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important applications of laser material processing technology. Handheld laser welding machines are the most common, typically operated by an operator holding the welding torch head to work on the welding area. Unlike traditional welding machines, the operation process is very short, and the welding effect is excellent. Handheld operation is also very flexible.

[0003] Currently, some laser welding methods use fixing bolts to clamp the plates together to secure them. Then, the workers can weld the adjacent plates. However, since welding requires flipping the plates, the above method does not allow for easy flipping. Workers need to unclamp the plates, flip them, and then clamp them again before welding. This process is very cumbersome and affects welding efficiency. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a clamping structure for laser welding.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a clamping structure for laser welding, including a mounting frame, wherein two symmetrically arranged first placement frames and second placement frames are provided inside the mounting frame, and connecting rods are fixedly provided at both ends of the second placement frame. The end of the connecting rod away from the second placement frame is inserted into the end of the first placement frame. A horizontally arranged placement plate is provided at the opposite end of the first placement frame and the second placement frame. A fixing plate is fixedly provided at the corner of the first placement frame and the second placement frame. A fixing bolt is threaded into the fixing plate. A positioning block is fixedly provided at the bottom of the fixing bolt. A horizontally arranged long rod is fixedly provided at the end of the first placement frame away from the second placement frame. The end of the long rod away from the first placement frame passes through the mounting frame. A first motor is fixedly provided on the outer wall of the mounting frame near the long rod. The output end of the first motor is coaxially fixedly provided on the long rod.

[0006] Preferably, the second placement frame has a rotating plate at the end away from the first placement frame, a drive rod is fixedly connected to the end of the rotating plate away from the second placement frame, a lead screw is fixedly connected to the end of the drive rod away from the rotating plate, and a rotating sleeve is rotatably provided at the end of the mounting frame near the drive rod, with a lead screw threaded into the rotating sleeve.

[0007] Preferably, an electric push rod is provided directly below both ends of the mounting frame, the output end of the electric push rod is coaxially fixed on the mounting frame, a base plate is fixedly provided below the mounting frame, the bottom of the electric push rod is fixedly provided on the base plate, and the four corners of the upper surface of the base plate are connected to the four corners of the mounting frame by telescopic rods.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. When the second placement frame moves toward the first placement frame, the plate is driven and clamped. Then, the fixing bolt is rotated by the rotating wheel to position the plate, thus completing the clamping and fixing of the plate and preventing the plate from shifting during welding.

[0010] 2. The second motor drives the rotating sleeve to rotate in both directions, causing the lead screw to move. The drive rod drives the second placement frame to move through the rotating plate. The distance between the first and second placement frames can be adjusted to accommodate plates of different lengths. When welding and flipping, it is only necessary to start the first motor to drive the long rod to rotate, thereby causing the first and second placement frames and the clamped plate to flip together, making it convenient to weld the other side. Unlike before, there is no need to cancel the clamping and fix it and then re-clamp it, reducing the operation steps and greatly improving the efficiency of welding operation.

[0016] 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.

[0017] Example: Figure 1-3 As shown, this utility model provides a clamping structure for laser welding, including a mounting frame 1. Inside the mounting frame 1, there are two symmetrically arranged first placement frames 11 and second placement frames 12. At one end of the first placement frames 11 and second placement frames 12, there are horizontally arranged placement plates 13. At the corner of the first placement frames 11 and second placement frames 12, there are fixed plates 14. Fixed bolts 15 are threaded into the fixed plates 14. A positioning block 16 is fixed at the bottom of the fixed bolts 15. A rotating wheel 17 with anti-slip strips on its surface is fixed at the top of the fixed bolts 15. This type of rotating wheel 17 can be rotated quickly and easily by the operator. A horizontally arranged long rod 18 is fixed at the end of the first placement frame 11 away from the second placement frame 12. The end of the long rod 18 away from the first placement frame 11 passes through the mounting frame 1. A first motor 19 is fixed on the outer wall of the mounting frame 1 near the long rod 18. The output end of the first motor 19 is coaxially fixed on the long rod 18.

[0018] Connecting rods 4 are fixedly provided at both ends of the second placement frame 12. The end of the connecting rod 4 away from the second placement frame 12 is inserted into the end of the first placement frame 11. The connecting rod 4 is mainly provided so that the first placement frame 11 and the second placement frame 12 can rotate together. At the same time, when the second placement frame 12 moves, it can also ensure that the two sides are parallel.

[0019] The second placement frame 12 has a rotating plate 23 at the end away from the first placement frame 11. A drive rod 22 is fixedly connected to the end of the rotating plate 23 away from the second placement frame 12. A lead screw 21 is fixedly connected to the end of the drive rod 22 away from the rotating plate 23. A rotating sleeve 2 is rotatably provided at the end of the mounting frame 1 near the drive rod 22. The lead screw 21 is threaded into the rotating sleeve 2. A second motor 25 is rotatably provided at the end of the mounting frame 1 near the lead screw 21. The output end of the second motor 25 is connected to the rotating sleeve 2 through two meshing gears 24. The second motor 25 mainly provides power for the rotation of the rotating sleeve 2, which facilitates the control of the second placement frame 12 to move closer to or further away from the first placement frame 11, increasing the distance between the two sides to accommodate plates of different lengths.

[0020] Electric push rods 31 are located directly below both ends of the mounting frame 1. The output ends of the electric push rods 31 are coaxially fixed on the mounting frame 1. The electric push rods 31 can push the entire mounting frame 1 up and down, so that the contact between the welded plate and the components above can be adjusted when it is flipped. It also makes it easy to adapt to different user heights and increases the practicality of the device. A base plate 3 is fixedly installed at the bottom of the mounting frame 1. The bottom of the electric push rods 31 is fixedly installed on the base plate 3. The four corners of the upper surface of the base plate 3 are connected to the four corners of the mounting frame 1 by telescopic rods 32. The base plate 3 and the telescopic rods 32 can support the electric push rods 31 when they push the mounting frame 1 to move, and at the same time, stabilize the four corners of the mounting frame 1. It is worth mentioning that, in order to facilitate the use of the device, casters with self-locking can be installed at the four corners of the bottom of the base plate 3 to facilitate the overall movement of the device.

[0021] Working principle: The operator can place the two plates to be welded into the first placement frame 11 and the second placement frame 12. Then, the second motor 25 drives the rotating sleeve 2 to rotate. When the rotating sleeve 2 rotates forward and backward, the threaded rod 21 on the rotating sleeve 2 will be driven to move forward or backward. The drive rod 22 fixed at the end of the threaded rod 21 will drive the second placement frame 12 to move through the rotating plate 23, thereby increasing the distance between the second placement frame 12 and the first placement frame 11 to accommodate plates of different lengths. At the same time, when the second placement frame 12 moves toward the first placement frame 11, the plates on the first placement frame 11 and the second placement frame 12 will be driven and clamped. Then, the operator can drive the fixing bolt 15 to rotate through the rotating wheel 17. The fixing bolt 15 will move down so that the positioning block 16 positions the plates on the placement plate 13. Finally, the clamping and fixing of the plates to be welded is completed to prevent displacement during welding.

[0022] Subsequently, workers can use a handheld welding torch to weld the contact surfaces of the plates. When it is time to flip the plates, workers only need to start the first motor 19 to rotate the long rod 18. The rotating long rod 18 will then rotate the first placement frame 11 and the second placement frame 12 together. As a result, the plates clamped and positioned on the first placement frame 11 and the second placement frame 12 will be flipped over together, allowing workers to directly and easily weld the other side. This greatly improves the efficiency of the welding operation and eliminates the need for workers to perform multiple steps to flip the plates, thus reducing their workload.

[0023] All standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
