Description

A multi-angle clamping device for welding Technical Field

[0001] This utility model relates to the field of metal welding equipment, specifically a multi-angle clamping device for welding. Background Technology

[0002] In modern industrial production, welding, as a key joining technology, is widely used in many fields such as machinery manufacturing, construction, and aerospace. With the increasing complexity and diversity of product structures, the requirements for welding precision and efficiency are also rising. However, traditional welding clamping tools face numerous challenges in practical applications.

[0003] Traditional welding clamping devices have a relatively simple structure and poor flexibility. When welding workpieces of different shapes and sizes, especially in scenarios requiring welding at specific angles, traditional clamps often struggle to achieve multi-angle adjustments, making welding operations extremely inconvenient. This not only consumes a significant amount of time and effort for debugging but also makes it difficult to guarantee welding accuracy, affecting product quality. Moreover, traditional clamps mostly use bolts to hold workpieces, a cumbersome method where bolts need to be tightened each time a workpiece is clamped. When welding small parts in batches, the frequent tightening of bolts makes the clamping process inefficient, severely hindering production progress.

[0004] Furthermore, during long-term use, the connecting parts of traditional clamps are prone to loosening, leading to unstable clamping. If the workpiece shifts during welding, it can not only cause welding failure but also potentially lead to safety accidents.

[0005] To address the aforementioned problems, this application proposes a multi-angle clamping device for welding. Summary of the Invention

[0006] To address the existing problems, this utility model provides a multi-angle clamping device for welding, which can effectively solve the problems mentioned in the background art.

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A multi-angle clamping device for welding includes two sets of clamps. Each clamp includes a sleeve and an adjusting arm. The sleeve is installed at one end of the adjusting arm, and the ends of the two adjusting arms away from the sleeve are movably connected. The sleeve has a U-shaped structure and a pressure plate is provided on its inner side. The pressure plate is connected to the sleeve through an adjusting rod.

[0009] As a further embodiment of this utility model: one of the adjusting arms has a threaded shaft fixed at the end away from the clamp, and the other adjusting arm has a through hole at the end away from the clamp. The shaft passes through the through hole and is connected to a nut by an external thread. An elastic pressure member is provided between the nut and the adjusting arm.

[0010] As a further embodiment of this utility model: the elastic pressure member includes a first pressure ring and a second pressure ring, and the first pressure ring and the second pressure ring are connected by a first spring.

[0012] As a further improvement of this utility model, the clamping direction of the sleeve forms a 45° angle with the length direction of the adjusting arm.

[0013] As a further embodiment of this utility model: the adjusting rod includes a threaded sleeve and a telescopic rod, one end of the telescopic rod is fixedly connected to the pressure plate, the other end of the telescopic rod moves through the threaded sleeve, the telescopic rod is provided with a stepped surface, and a second spring is provided between the stepped surface and the top of the threaded sleeve.

[0014] As a further improvement of this utility model: a threaded ring is fixedly connected to the sleeve, and the threaded sleeve is threadedly connected to the threaded ring on the sleeve.

[0015] As a further embodiment of this utility model: a clamping cavity is formed between the pressure plate and the inner wall of the jacket, and the inner wall of the clamping cavity is provided with an arc-shaped groove along the clamping direction.

[0016] As a further improvement of this utility model, the bottom walls of the two jackets are on the same plane.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses two rotatably connected clamps, in conjunction with an adjustable pressure plate inside the clamping sleeve, to hold and fix the workpiece to be welded, achieving flexible adjustment at multiple angles.

[0025] 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.

[0026] Please refer to Figures 1-6. This utility model provides a multi-angle clamping device for welding, including two sets of clamps. Each set of clamps includes a clamp 1 and an adjusting arm 2. The clamp 1 is installed at one end of the adjusting arm 2. The ends of the two adjusting arms 2 away from the clamp 1 are movably connected. The clamp 1 has a U-shaped structure and a pressure plate 3 is provided on the inner side. The pressure plate 3 is connected to the clamp 1 through an adjusting rod 9. The pressure plate 3 and the bottom side plate of the clamp 1 clamp the workpiece to be welded. The two adjusting arms 2 rotate relative to each other to adapt to welding at different angles of the workpiece.

[0027] As shown in Figure 1-2, further, one of the adjusting arms 2 has a threaded shaft 4 fixed at the end away from the sleeve 1, and the other adjusting arm 2 has a through hole 5 at the end away from the sleeve 1. The shaft 4 passes through the through hole 5 and is connected to a nut 6 by an external thread. An elastic pressure member 7 is provided between the nut 6 and the adjusting arm 2. The two adjusting arms 2 rotate relative to each other about the shaft 4 as the axis, and the nut 6 and the elastic pressure member 7 are used to press the two adjusting arms 2 together to keep them relatively stable. In the specific manufacturing process, a handle can be provided on the side wall of the nut 6 to facilitate the rotation of the nut 6. Specifically, the elastic pressure member 7 includes a first pressure ring 71 and a second pressure ring 72. The first pressure ring 71 and the second pressure ring 72 are connected by a first spring 73. The first pressure ring 71 is tightly fitted with the adjusting arm 2, and the second pressure ring 72 is fitted with the nut 6. The first spring 73 applies pressure to the first pressure ring 71, so that the two adjusting arms 2 are tightly fitted together. After the angle adjustment is completed, the friction force prevents the two adjusting arms 2 from rotating. In order to improve the stability of the two adjusting arms 2 after adjustment, the contact part between the first pressure ring 71 and the adjusting arm 2 adopts a ring-shaped serrated meshing, thereby improving the clamping stability.

[0028] As shown in Figure 1, further, an angle scale 8 is provided between the two adjusting arms 2. The angle scale 8 is embedded and fixed on one of the adjusting arms 2. Specifically, the angle scale 8 is a semi-circular plate, which is set between the two adjusting arms 2. It does not affect the rotation between the two adjusting arms 2, and at the same time can improve the measurement accuracy. The included angle α between the two adjusting arms 2 can be seen intuitively. The welding angle between the two parts to be welded can be determined by using the angle scale 8. The clamping direction of the clamp 1 is at a 45° angle with the length direction of the adjusting arm 2. That is, after the parts to be welded are clamped, the included angle between the parts to be welded and the adjusting arm 2 is 45°. Thus, the included angle between the two parts to be welded can be calculated.

[0029] As shown in Figures 3 and 4, the adjusting rod 9 includes a threaded sleeve 91 and a telescopic rod 92. A threaded ring 11 is fixedly connected to the clamp 1. The threaded sleeve 91 is threadedly connected to the threaded ring 11 on the clamp 1. One end of the telescopic rod 92 is fixedly connected to the pressure plate 3, and the other end of the telescopic rod 92 moves through the threaded sleeve 91. The telescopic rod 92 has a stepped surface. A second spring 93 is provided between the stepped surface and the top of the threaded sleeve 91. The telescopic rod 92 is composed of two round rods that are thinner at the top and thicker at the bottom. The intersection of the two round rods forms a stepped surface. The stepped surface abuts against one end of the second spring 93. The thinner round rod at the top passes through the threaded sleeve 91 and is fixedly connected to a limiting ring 94. The limiting ring 94 abuts against the top surface of the threaded sleeve 91. The second spring 93 drives the telescopic rod 92 to slide along the threaded sleeve 91. This works in conjunction with the pressure plate 3 to achieve elastic pressing and fixing of the workpiece to be welded. Depending on the size of the workpiece to be welded, the threaded sleeve 91 is rotated to adjust the size space of the pressing and fixing. Furthermore, a clamping cavity is formed between the pressure plate 3 and the inner wall of the jacket 1. The inner wall of the clamping cavity is provided with an arc groove 10 along the clamping direction to maintain the stability of the clamping. No tools are needed to fix it. After welding is completed, the welded part can be easily taken out by pulling the telescopic rod 92 upward, which greatly shortens the clamping time of a single welded part and improves production efficiency.

[0030] As shown in Figure 1, and in order to ensure that the parts to be welded are on the same plane, the bottom walls of the two clamps 1 are on the same plane. In the specific preparation, when the two adjusting arms 2 are welded and fixed to the corresponding ends of the clamps 1, they are staggered. The staggered size is the thickness of the bottom wall of the clamp 1, so that the inner wall surfaces of the two clamps 1 are on the same plane. When it is necessary to weld two materials on the same plane, this design can ensure that the two materials remain horizontally aligned in the clamping state, avoid material misalignment due to inconsistent clamp height, and thus ensure the accuracy and stability of welding.

[0031] Its working principle is as follows: by rotating the two clamps, the workpiece to be welded is clamped and fixed in conjunction with the adjustable pressure plate 3 inside the clamp 1, so as to achieve flexible adjustment of multiple angles. In the welding operation, the angle of the clamp 1 can be quickly adjusted according to the shape of the metal part, the welding position and the process requirements, so that the clamped object is in the best welding posture, which is convenient for the welder to operate, significantly improves welding efficiency and accuracy, and reduces welding quality problems caused by unsuitable angles.
