Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a clamping mechanism for welding equipment. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Welding equipment, as a key tool for realizing the welding process, has a crucial impact on product quality due to its performance and precision.

[0003] As a crucial component of welding equipment, the clamping mechanism is primarily responsible for the stable clamping and precise positioning of the workpiece. Its performance directly impacts the smoothness and accuracy of the welding process. In actual welding operations, it is often necessary to handle pipes with different cross-sectional shapes, such as round and square tubes. However, most welding equipment currently on the market is designed with clamping schemes tailored to a single cross-sectional shape. This makes it difficult for clamping mechanisms specifically designed for round tubes to stably fix square tubes, while clamping mechanisms designed for square tubes cannot effectively clamp round tubes. This lack of versatility in existing clamping mechanisms limits the working efficiency of welding equipment to some extent. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0020] Please refer to Figures 1-3As shown, this application discloses a clamping mechanism for welding equipment, including a base 1, a clamping plate 2, and a mounting base 3. The base 1 is used to fix to the worktable of the welding equipment, such as by connecting the base 1 to the worktable with bolts. The clamping plate 2 is slidably connected to the base 1, and an adjustable clamping opening is formed between the clamping plate 2 and the base 1. The clamping opening is used to clamp the workpiece. The clamping plate 2 is slidably connected to the mounting base 3, and the mounting base 3 is connected to a driving member 5. The driving member 5 is used to drive the clamping plate 2 to slide relative to the base 1 and the mounting base 3 to adjust the size of the clamping opening. The clamping plate 2 is provided with a clamping part, and the clamping part is constructed with a stepped structure 4. The stepped structure 4 ensures that when clamping a square tube, the horizontal and side surfaces of the step fit against two adjacent surfaces of the square tube, forming a stable constraint and thus guaranteeing clamping stability. When clamping a round tube, the two edges of the stepped structure 4 form line contact with the outer wall of the round tube, allowing the round tube to be stably clamped at the clamping opening. The technical solution of this application can stably clamp both square and round tubes, exhibiting wide versatility. Furthermore, by adjusting the size of the clamping opening through the driving component 5, the clamping mechanism can adapt to pipe fittings of different diameters, further improving the versatility of the clamping mechanism.

[0021] For further details, please refer to the following: Figure 4 As shown, the base 1 includes a base plate 6 and a baffle 8 perpendicular to the base plate 6. The baffle 8 is located at the end away from the driving component 5. Two wing plates 7 extend from the side of the base plate 6 away from the baffle 8, with an obtuse angle between the wing plates 7 and the base plate 6. The clamping plate 2 is slidably connected to the two wing plates 7 respectively. Typically, the base plate 6 has several mounting holes for connecting to the worktable of the welding equipment. The perpendicular arrangement of the baffle 8 to the base plate 6 ensures that the workpiece is stably pressed between the clamping plate 2 and the baffle 8. Preferably, the base plate 6, the baffle 8, and the two wing plates 7 are integrally formed. Since the base 1 is used to bear the weight of the workpiece for a long time, the integrally formed structure gives the base 1 higher structural strength when bearing the weight of the workpiece and the clamping force, thereby ensuring the stability of the workpiece clamping.

[0022] Furthermore, the two wing plates 7 are arranged in parallel, and the clamping plate 2 is slidably connected to the base 1 through the first pin 9. The wing plate 7 has a first strip hole 10 along its length. Under the action of the driving member 5, the clamping plate 2 slides along the first strip hole 10. The clamping plate 2 is at least partially located between the two wing plates 7. The clamping plate 2 is provided with a first connecting hole 14. The first pin 9 passes through the first connecting hole 14 and the first strip hole 10 to connect the clamping plate 2 to the base 1, while allowing the clamping plate 2 to slide relative to the wing plate 7 through the first pin 9 along the first strip hole 10. Specifically, the first connecting hole 14 is an oblong hole, and the width of the first connecting hole 14 is the same as the width of the first strip hole 10. The shape of the first pin 9 is adapted to the shape of the first connecting hole 14, that is, the shape of the cross-section of the first pin 9 is consistent with the shape of the first connecting hole 14, and the size is adapted. This makes the first pin 9 a flat elongated structure. This arrangement can prevent the clamping plate 2 from shaking or rotating around the first pin 9, thereby ensuring the stability and reliability of clamping.

[0023] like Figure 5 and Figure 6 As shown, in one embodiment of this disclosure, the clamping plate 2 includes a connecting block 11, a stepped structure 4 is disposed at the first end of the connecting block 11, a first connecting hole 14 is disposed at the second end of the connecting block 11, and two parallel ear plates 12 extend from the second end of the connecting block 11 toward the driving member 5. The two ear plates 12 and the connecting block 11 form a "U"-shaped structure, and the mounting base 3 is at least partially located between the two ear plates 12. The clamping plate 2 and the mounting base 3 are connected by a second pin 22. A second connecting hole 15 is constructed on the ear plate 12, and a second strip hole 13 is provided at the corresponding position of the mounting base 3. The second pin 22 passes through the second connecting hole 15 and the second strip hole 13 to connect the clamping plate 2 and the mounting base 3, while allowing the clamping plate 2 to slide relative to the mounting base 3 along the second strip hole 13 via the second pin 22. Specifically, the second connecting hole 15 is an oblong hole, and the width of the second connecting hole 15 is the same as the width of the second strip hole 13. The shape of the second pin 22 is adapted to the shape of the second connecting hole 15, that is, the shape of the cross-section of the second pin 22 is consistent with the shape of the second connecting hole 15 and the size is adapted. This makes the second pin 22 a flat strip structure. This setting can prevent the clamping plate 2 from shaking or rotating around the second pin 22, thereby ensuring the stability and reliability of clamping.

[0024] It should be noted that the driving component 5 in this application is a cylinder, and the piston rod of the cylinder is connected to the mounting base 3 by a thread. The extension and retraction of the piston rod of the cylinder can directly push or pull the entire mounting base 3, causing it to move horizontally. When the mounting base 3 is driven by the driving component 5, it transmits the driving force to the clamping plate 2 through the second pin 22. The clamping plate 2 receives the driving force from the second pin 22, causing it to slide along the first strip hole 10. It can be understood that if the driving component 5 applies a pushing force to the mounting base 3, the clamping plate 2 slides downward along the first strip hole 10, and the clamping opening gradually becomes smaller; if the driving component 5 applies a pulling force to the mounting base 3, the clamping plate 2 slides upward along the first strip hole 10, and the clamping opening gradually increases. Understandably, the second strip-shaped hole 13 allows the clamping plate 2 to slide relative to the mounting base 3 as it slides along the first strip-shaped hole 10, creating a dynamic relative displacement between the clamping plate 2 and the mounting plate. This prevents jamming caused by assembly errors and ensures smoother sliding of the clamping plate 2 along the first strip-shaped hole 10. Furthermore, this application uses a driving component 5 to adjust the size of the clamping opening, eliminating the need for manual adjustment and making it more convenient to use.

[0025] Please continue reading. Figure 5 and Figure 6 As shown, the stepped structure 4 includes a first outer surface 16, a first inner surface 17, and a first side surface 18. The first outer surface 16 and the first side surface 18 are parallel and both are arranged vertically. The first inner surface 17 is located between the first outer surface 16 and the first side surface 18, and is connected to both the first outer surface 16 and the first side surface 18. The first inner surface 17 is parallel to the horizontal plane, and the distance from the first outer surface 16 to the ear plate 12 is greater than the distance from the first side surface 18 to the ear plate 12. In particular, the first inner surface 17 and the first side surface 18 are perpendicular to each other, and the connection between the first inner surface 17 and the first side surface 18 is not chamfered, so that the first inner surface 17 and the first side surface 18 form a 90-degree positioning angle, achieving a large area of ​​surface contact with the two adjacent outer surfaces of the square tube. This arrangement not only improves the clamping force but also provides precise positioning, effectively preventing the square tube from rotating during welding.

[0026] Furthermore, the first side surface 18 is connected to a second inner surface 19, which faces the base plate 6 and is parallel to the first inner surface 17. A first arc-shaped surface 20 is provided at the connection between the first side surface 18 and the second inner surface 19, and a second arc-shaped surface 21 is provided at the connection between the first outer surface 16 and the first inner surface 17. The first arc-shaped surface 20 and the second arc-shaped surface 21 are located at different heights in space, forming two discrete constraint structures with the contact points of the two with the circular tube. When the pipe being welded by the welding equipment is a circular tube, the first arc-shaped surface 20 and the second arc-shaped surface 21 serve as clamping contact surfaces. The arc-shaped surface design not only increases the contact area with the circular tube but also avoids damage to the workpiece surface during clamping. In addition, the arc-shaped surface allows the circular tube to have a slight self-adjustment at the beginning of clamping, i.e., an adaptive process, thereby making the clamping more stable and reliable.

[0027] It is understandable that, regardless of whether a square or round tube is clamped, one side of the fitting is constrained by the stepped structure 4, and the other side is constrained by the base 1, so that the fitting is stably clamped in the clamping opening formed by the stepped structure 4 and the base 1.

[0028] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
