[0002] A sealing ring butt welding device is a device used to produce sealing rings. This device typically includes a conveying mechanism, a cutting mechanism, a flipping robotic arm, and a welding structure. The sealing strip is mounted on the conveying device, which then transports it to the cutting device. The cutting device is equipped with a sliding clamping mechanism that holds the ends of the sealing strip and pulls them out a certain distance. Two clamping jaws on the flipping robotic arm hold both ends of the sealing strip, and then the cutting device cuts it. Subsequently, the two clamping jaws on the flipping robotic arm align the two ends of the sealing strip by flipping it, and then it is placed into the welding structure for welding. This process is repeated to complete the automated production of sealing rings.

[0003] However, different sealing parts require different sealing ring sizes. Especially when customizing non-standard parts, the sealing ring size needs to be adjusted according to requirements, and existing sealing ring butt welding devices are difficult to adjust. Utility Model Content

[0026] 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.

[0027] Please see Figures 1 to 3 This invention discloses a sealing ring butt welding device, comprising a conveying assembly, a cutting assembly, a flipping assembly, and a welding assembly. The cutting assembly includes a mounting frame 1, which is frame-shaped. An inlet end 2 is fixedly mounted on the mounting frame 1. The inlet end 2 includes a base plate 21 fixedly mounted on the upper end of the mounting frame 1. A clamping roller 22, which is slidably mounted on the upper end of the base plate 21, is mounted on the mounting frame 1. A cutting mechanism 23 is fixedly mounted on the side of the mounting frame 1 near the inlet end 2 away from the conveying assembly. A fixed-distance slide rail 31 and a ball screw mechanism 32 are fixedly mounted on the mounting frame 1. The ball screw mechanism 32 is connected to... A drive motor is fixedly mounted on the mounting frame 1. A clamping member 4 is slidably mounted on the fixed-distance slide rail 31. The clamping member 4 is fixedly mounted on the output end of the ball screw mechanism 32. The clamping member 4 includes two clamping plates 41. A support member 51 is rotatably mounted on the mounting frame 1. The support member 51 is located on the side of the cutting mechanism 23 away from the feed end 2. The support member 51 is connected to a drive member 514. An L-shaped block 52 is fixedly mounted on the clamping plate 41 on the bottom side. A rectangular groove is formed between the L-shaped block 52 and the clamping plate 41. The distance between the support member 51 and the cutting mechanism 23 and the width of the rectangular groove are greater than the width of the clamping claw of the flipping component.

[0028] Specifically, by setting the clamping member 4 on the ball screw mechanism 32 and the fixed-distance slide rail 31, the sliding distance of the clamping member 4 on the ball screw mechanism 32 and the fixed-distance slide rail 31 is controlled, thereby controlling the length of the cut sealing strip and thus controlling the size of the sealing ring.

[0029] In some feasible methods, the conveying component, flipping component, and welding component are all existing technologies and will not be described in detail here. The mounting frame 1 is a rectangular frame, the base plate 21 is a rectangular plate, and the clamping roller 22 is a round roller. To facilitate the clamping of the sealing strip, grooves adapted to the shape of the sealing strip can also be provided on the clamping roller 22 and the base plate 21. Support rods fixedly mounted on the mounting frame 1 are provided at both ends of the base plate 21. Sliding grooves are provided on the support rods, and sliders are slidably mounted in the sliding grooves. Adjusting screws threadedly connected to the sliders are rotatably mounted in the sliding grooves. The clamping roller 22 is rotatably mounted on the sliders at both ends. The downward pressure on the sealing strip can be adjusted by adjusting the screws, which can also accommodate sealing strips with different cross-sectional sizes.

[0030] The fixed-distance slide rail 31 is cylindrical, and two fixed-distance slide rails 31 are arranged on both sides of the clamping member 4. The bottom of the clamping member 4 is provided with a mounting plate, and an arc ring adapted to the fixed-distance slide rail 31 is fixedly installed on the mounting plate. Two sets of ball screw mechanisms 32 are provided, located on the sides of the two fixed-distance slide rails 31 respectively. The two ball screw mechanisms 32 are connected to the same drive motor through a gearbox and connecting rod for synchronous drive. The clamping member 4 is prior art and includes two clamping plates 41. The clamping plates 41 are controlled by a cylinder to clamp the sealing strip.

[0031] When adapting to sealing strips of different sizes, the stopping position of the clamping member 4 varies, requiring the clamping claws of the flipping assembly to be adjusted accordingly. To reduce the need for adjustment of the flipping assembly, a reset point is provided on the mounting frame 1. When the length of the sealing strip adapted to the clamping member 4 exceeds the reset point, the clamping member 4 will return to the reset point after being pulled out to a sufficient length. A support member 51 and an L-shaped block 52 are installed on the mounting frame 1. The support member 51 and the L-shaped block 52 provide support at both ends of the sealing strip. When the sealing strip droops due to reset, a space is formed between the support member 51 and the cutting mechanism 23, and between the L-shaped block 52 and the clamping plate 41, for the clamping claws of the flipping assembly to insert and clamp.

[0032] The support member 51 can be configured as a gantry frame, and the drive member 514 can be configured as a drive motor, allowing the support member 51 to rotate without affecting the sliding of the clamping member 4. L-shaped slide rails are provided on both sides of the bottom of the clamping plate 41, and the L-shaped block 52 is slidably installed on the bottom of the clamping plate 41. A spring is provided between the L-shaped block 52 and the clamping plate 41. When the clamping plate 41 moves to the feed end 2 to clamp the sealing strip, the L-shaped block 52 is squeezed close to the clamping plate 41, reducing the influence of the size of the L-shaped block 52 on the clamping plate 41 to clamp the sealing ring.

[0033] As one specific embodiment of the sealing ring butt welding device provided in the application, please refer to Figure 1 The support member 51 includes a support frame 512 that is rotatably mounted on the mounting frame 1, and a support roller 513 is rotatably mounted on the upper end of the support frame 512.

[0034] Overall, by setting the support roller 513, scratches on the sealing strip are reduced during the rotation and reset process of the support member 51.

[0035] Furthermore, the driving component 514 is an arc-shaped surface disposed at the bottom of the L-shaped block 52, and the driving component 514 also includes a return spring 511 disposed between the support component 51 and the mounting bracket 1.

[0036] It should be understood that by setting the driving component 514 to the arc-shaped surface at the bottom of the L-shaped block 52, the support component 51 is pushed to rotate and make room during the sliding process of the clamping component 4, and is reset by the return spring 511 after the clamping component 4 slides away.

[0037] In some feasible ways, the mounting positions of the support 51 and the cutting mechanism 23 should be such that the support 51 does not interfere with each other when rotating.

[0038] As another specific embodiment of the sealing ring butt welding device provided in the application, please refer to Figure 2 The cutting mechanism 23 includes a bottom support plate 231 that is slidably mounted on the lower side of the mounting frame 1 and a cutting blade 232 on the upper side. Both the bottom support plate 231 and the cutting blade 232 are connected to a drive cylinder.

[0039] Depending on the specific application scenario, after the clamping component 4 is reset, the clamping claws of the flipping component clamp the two ends of the sealing strip. The bottom support plate 231 and the cutting blade 232 move to the position of the sealing strip under the action of the driving cylinder, and the cutting blade 232 continues to move down to complete the cutting.

[0040] In some feasible configurations, C-shaped slide rails are fixedly installed on both sides of the lower side of the mounting bracket 1, and the bottom support plate 231 is slidably installed in the C-shaped slide rails on both sides. A gantry frame is installed on the upper side of the mounting bracket 1, and the cutting blade 232 is slidably installed in the gantry frame on both sides.

[0041] As one specific embodiment of the sealing ring butt welding device provided in the application, please refer to Figure 1 The mounting bracket 1 is fixedly equipped with a limit switch 6, and the bottom of the clamp 4 is provided with a trigger rod 61. The limit switch 6 is connected to the flip assembly via a signal.

[0042] It should be understood that by setting the limit switch 6, the position of the clamp 4 is confirmed to facilitate the operation of the flipping component.

[0043] As one specific embodiment of the sealing ring butt welding device provided in the application, please refer to Figure 3 A limiting plate 62 is slidably mounted on the fixed-distance slide rail 31. A force sensor 63 is fixedly mounted on the limiting plate 62. The force sensor 63 is connected to the drive motor of the ball screw mechanism 32. A fixing member 64 is provided between the limiting plate 62 and the fixed-distance slide rail 31.

[0044] It should be understood that by setting the limit plate 62 and the force sensor 63, when the clamping member 4 moves to the set length, the force sensor 63 detects the positioning signal. At the same time, the signal value of the force sensor 63 can be used to determine whether the clamping member 4 stops at this position or has a tendency to move backward, so as to correct the sliding distance.

[0045] In some feasible methods, the limiting plate 62 is rectangular, and a sliding block adapted to the fixed distance slide rail 31 is fixedly installed at the bottom of the limiting plate 62. The sliding block is threaded with a fastening screw on its side, and the fastening screw abuts against the fixed distance slide rail 31.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
