[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0017] The following will further describe the present utility model with reference to the accompanying drawings of the specification.

[0018] The present utility model provides the following technical solutions:

[0019] As shown in the figure Figure 1-2As shown in the figure, the utility model discloses a jaw for clamping a flange, which comprises a transmission mechanism 1 and a clamping mechanism 2. The top end of the clamping mechanism 2 is connected to the transmission mechanism 1, and the transmission mechanism 1 drives the clamping mechanism 2 to perform a clamping action. The clamping mechanism 2 includes two symmetrically arranged clamping arms 3. A clamping block 4 is arranged at the bottom end of the clamping arm 3, and the clamping block 4 is connected to the clamping arm 3. A V-shaped surface 5 is arranged on the clamping block 4, and a flange positioning groove 6 for positioning the flange is provided on the V-shaped surface 5. Specifically, in this design, by arranging the V-shaped surface 5 on the clamping block 4 and providing the flange positioning groove 6 on the V-shaped surface, the quick positioning and clamping of flanges of different specifications can be realized. In addition, the clamping mechanism 2 adopts two symmetrically arranged clamping arms 3, which not only ensures the stability of clamping but also can adapt to various flange shapes. In practical applications, the transmission mechanism 1 drives the opening and closing of the clamping arms 3, so that the clamping block 4 clamps the flange on the V-shaped surface 5. The flange positioning groove 6 on the clamping block 4 can ensure the stability of the flange during the clamping process and prevent it from sliding or shifting during the clamping process.

[0020] Furthermore, the V-shaped surface 5 has a first inclined surface portion 7 and a second inclined surface portion 8. The flange positioning groove 6 is arranged in a vertical groove structure and is respectively provided on the first inclined surface portion 7 and the second inclined surface portion 8. Specifically, in this embodiment, the design of the V-shaped surface 5 not only enhances the clamping ability of the clamping block 4 but also enables the jaw to better adapt to flanges of different sizes. The first inclined surface portion 7 and the second inclined surface portion 8 respectively constitute both sides of the V-shaped surface 5. This design enables the clamping block 4 to better fit the edge of the flange when clamping the flange, thereby ensuring the stability and reliability of clamping. At the same time, the flange positioning groove 6 is designed in a vertical groove structure and is respectively provided on the first inclined surface portion 7 and the second inclined surface portion 8. In this way, when clamping flanges of different sizes, the flange can be quickly positioned through the flange positioning groove 6. The design of the vertical groove structure also enables the clamping block 4 to better fix the flange during the clamping process and prevent it from sliding or shifting during the clamping process.

[0021] Furthermore, there is an arc chamfer portion 9 between the first inclined surface portion 7 and the second inclined surface portion 8. Specifically, in this embodiment, the design of the arc chamfer portion 9 between the first inclined surface portion 7 and the second inclined surface portion 8 further improves the clamping effect of the clamping block 4. In practical applications, it can better fit the edge of the flange, thereby further improving the stability and reliability of clamping. Especially when clamping larger-sized flanges, the design of the arc chamfer portion 9 can reduce the gap between the clamping block 4 and the flange, making the clamping tighter and preventing the flange from shaking or falling off during the clamping process. In addition, the arc chamfer portion 9 can also reduce the damage to the flange surface by the clamping block 4 during the clamping process and protect the integrity of the flange.

[0022] Furthermore, the transmission mechanism 1 includes a transmission box 10 and a power source 11. The power source 11 is disposed inside the transmission box 10. The top end of the clamping arm 3 extends into the transmission box 10 and is connected to the power source 11. A limiting block 12 is arranged between the clamping arms 3, and the limiting block 12 is disposed between the parts of the clamping arms 3 located inside the transmission box 10. Specifically, in this embodiment, the power source 11 is a cylinder.

[0023] The cylinder is disposed inside the transmission box 10, and the opening and closing actions of the clamping arm 3 are realized by air pressure drive. The top end of the clamping arm 3 extends into the transmission box 10 and is connected to the cylinder. The connection structure between the cylinder and the clamping arm 3 is prior art, so it will not be described in detail here to ensure that the driving force of the cylinder can be accurately transmitted to the clamping arm 3. At the same time, the limiting block 12 arranged between the clamping arms 3 can effectively limit the opening and closing range of the clamping arm 3, prevent the clamping arm 3 from exceeding the safe range during the movement, and ensure the safe and stable operation of the clamping mechanism 2.

[0024] Furthermore, the limiting block 12 is triangularly arranged. A positioning hole 13 is formed on the limiting block 12, and a positioning shaft 14 is disposed inside the positioning hole 13. The positioning shaft 14 passes through the positioning hole 13 and is connected to the inner wall of the transmission box 10. The limiting block 12 is fixed inside the transmission box 10 through the positioning shaft 14. Specifically, in this embodiment, the limiting block 12 adopts a triangular design. This shape not only has a stable structure but also can effectively limit the opening and closing range of the clamping arm 3. A positioning hole 13 is formed on the limiting block 12, and a positioning shaft 14 is disposed inside the positioning hole 13. The limiting block 12 is fixed inside the transmission box 10 through the positioning shaft 14, making the position of the limiting block 12 stable and reliable. At the same time, the design of the positioning shaft 14 also makes the installation and disassembly of the limiting block 12 more convenient and fast, facilitating subsequent maintenance and replacement.

[0025] Furthermore, a clamping arm connection end 15 is arranged on the clamping block 4. The clamping arm connection end 15 protrudes from the side of the clamping block 4 away from the flange positioning groove 6 towards the clamping arm 3. A connection groove 16 is arranged on the clamping arm 3, and the clamping arm connection end 15 extends into the connection groove 16 and is connected to the clamping arm 3. Specifically, in this embodiment, the design of the clamping arm connection end 15 on the clamping block 4 makes the connection between the clamping block 4 and the clamping arm 3 more stable and reliable. The clamping arm connection end 15 protrudes from the side of the clamping block 4 away from the flange positioning groove 6 towards the clamping arm 3. This design enables the clamping arm connection end 15 to better connect with the clamping arm 3. At the same time, the connection groove 16 arranged on the clamping arm 3 can cooperate with the clamping arm connection end 15 to realize the quick installation and disassembly of the clamping block 4 and the clamping arm 3.

[0026] Further, a rotation hole 17 is formed on the clamping arm connection end 15, a connection hole 18 corresponding to the rotation hole is arranged on the clamping arm 3, a rotating shaft 19 is arranged between the rotation hole 17 and the connection hole 18, and the rotating shaft 19 passes through the connection hole 18 and the rotation hole 17 to connect the clamping arm 3 and the clamping block 4. Specifically, in this embodiment, by forming a rotation hole 17 on the clamping arm connection end 15 and arranging a corresponding connection hole 18 on the clamping arm 3, the clamping block 4 and the clamping arm 3 can be rotatably connected. This design not only makes the clamping mechanism 2 more flexible when clamping the flange, but also can adapt to flanges of different shapes and sizes. At the same time, the rotating shaft 19 arranged between the rotation hole 17 and the connection hole 18 can ensure the stable and reliable connection between the clamping block 4 and the clamping arm 3, preventing loosening or falling off during the clamping process.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
