[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0031] In order to solve the technical problems in the background art, such as Figure 1-3 As shown, this application provides a technical solution: a stainless steel pipe clamping device, characterized as follows:

[0032] The fixed base 1 is used to fix the entire clamping device and provide stability. A guide rail 2 is provided on the fixed base 1 to guide the movement of the movable base 3 and ensure that it slides smoothly along a predetermined path.

[0033] The movable seat 3 is designed with a rectangular structure, and multiple rollers 4 are set at its four corners. These rollers 4 can roll along the guide rail 2, allowing the movable seat 3 to move freely on the fixed seat 1 to adapt to the clamping requirements of pipe fittings in different positions. The lifting platform 5 is set above the movable seat 3, and telescopic rods 6 are installed at its four corners. One end of the telescopic rod 6 is connected to the movable seat 3, and the other end is connected to the lifting platform 5, allowing the lifting platform 5 to move up and down to adjust the clamping height. The cylinder 7 is set on the movable seat 3, and its internal piston rod 8 is connected to the bottom of the lifting platform 5. Driven by the cylinder 7, the telescopic rod 6 achieves extension and retraction, thereby controlling the lifting of the lifting platform 5. The V-shaped clamping plate 9 is vertically set on the lifting platform 5 to clamp stainless steel pipe fittings, providing stable clamping force and preventing the pipe fittings from sliding or rotating during processing. The middle part of the V-shaped clamping plate 9 is V-shaped, which has a centering effect. The support seat 10 is set on the fixed seat 1 and has a top surface 11, a side surface 12, and a bottom surface 13. A through hole 14 is provided on the top surface 11. A hydraulic cylinder 15 is disposed inside the support base 10, and an adjusting rod 16 inside the cylinder passes through the through hole 14 to transmit the thrust of the hydraulic cylinder 15. One end of the Y-shaped connecting rod 17 is hinged to the adjusting rod 16, and the other end is connected to a C-shaped block 18. This design allows the C-shaped block 18 to move under the drive of the hydraulic cylinder 15 to clamp or release the pipe fitting. The lateral structure of the T-shaped block 19 is connected to the top surface 11, and one end of the connecting rod 20 is hinged to the vertical structure. The other end of the connecting rod 20 is hinged to the middle of the Y-shaped connecting rod 17. Specifically, the T-shaped block 19 is an inverted T-shape. Driven by the hydraulic cylinder 15, the C-shaped block 18 is pressed against the V-shaped clamping plate 9 to clamp the pipe fitting.

[0034] It should be noted that roller 4 mainly consists of two parts: rollers and roller discs at both ends. The rollers, located at the center of roller 4, are cylindrical rolling elements, while the roller discs at both ends are the supporting structures for the rollers. Together, they constitute the main body of roller 4. The I-beam structure design of roller 4 gives it high stability and load-bearing capacity. The rollers are located at the center of the I-beam structure, and the roller discs at both ends are symmetrically distributed. This design allows roller 4 to remain smooth when rolling along guide rail 2, reducing vibration and noise, and improving the movement accuracy of moving seat 3.

[0035] Furthermore, two V-shaped clamping plates 9 are arranged in parallel, allowing for simultaneous clamping of the stainless steel pipe fitting from both sides, providing a more balanced and stable clamping force. These two V-shaped clamping plates 9 are located on either side of the C-block 18, ensuring that the V-shaped clamping plates 9 on both sides can clamp the pipe fitting synchronously when the hydraulic cylinder 15 drives the C-block 18 to move. Precise mechanical design ensures the synchronous movement of the two V-shaped clamping plates 9, thus preventing pipe deformation or damage due to uneven clamping. Using the adjusting rod 16 of the hydraulic cylinder 15, the pressure of the C-block 18 on the V-shaped clamping plates 9 can be precisely controlled, thereby adjusting the clamping force to accommodate stainless steel pipe fittings of different diameters and materials.

[0036] It should be noted that the fixed column 21 is vertically mounted on the fixed base 1, serving a supporting and fixing function. The limiting block 22 is located on the top and sides of the fixed column 21, primarily used to limit the movement range of the movable base 3. The design of the limiting block 22 ensures that the movable base 3 will not exceed the set movement range when rolling along the guide rail 2, thereby avoiding equipment damage or unstable pipe clamping due to excessive movement. The fixed column 21 and the limiting block 22 are fixedly connected, ensuring that the limiting block 22 can be firmly fixed to the fixed column 21 without affecting the normal movement of the movable base 3. The material of the limiting block 22 should have sufficient strength and wear resistance to withstand the impact force generated by the movable base 3 during movement.

[0037] Furthermore, the limiting block 22 is designed in an inverted L-shape. One lateral end of the limiting block 22 is connected to the top of the fixed post 21. This connection ensures that the limiting block 22 is stably fixed on the fixed post 21 and will not shift during operation. The vertical side of the limiting block 22 abuts against the fixed post 21 parallel to it and is located between the fixed post 21 and the movable seat 3. This design allows the limiting block 22 to directly contact the movable seat 3, limiting its movement along the guide rail 2. When the movable seat 3 moves along the guide rail 2 to the position of the limiting block 22, the inverted L-shaped limiting block 22 will prevent the movable seat 3 from moving further, achieving the limiting function. This ensures that the movable seat 3 will not exceed the predetermined working area, increasing operational safety. The design of the inverted L-shaped limiting block 22 not only provides an effective limiting effect but also increases the safety and stability of the entire clamping device due to its structural stability.

[0038] It should be noted that multiple fixing posts 21 are evenly distributed on both sides of the guide rail 2, forming a rectangular array layout. This layout provides structural symmetry and stability, while also facilitating the installation and adjustment of the limiting block 22. The rectangular array layout of the fixing posts 21 makes the entire clamping device more structurally balanced, helping to distribute the load and reduce local stress concentration. The size and spacing of the fixing posts 21 are determined according to the length of the guide rail 2 and the size of the moving seat 3 to ensure the stability of the moving seat 3 during movement and the effective limiting of the limiting block 22. The fixing posts 21 are firmly fixed to the fixing seat 1 by welding, bolting, or other fixing methods to ensure stability during the movement of the moving seat 3 and the limiting of the limiting block 22.

[0039] It should be noted that the limiting blocks 22 are evenly distributed between every two opposing fixed posts 21, i.e., on both sides of the guide rail 2. This distribution ensures that the movement of the movable seat 3 on the guide rail 2 is uniformly restricted, thereby guaranteeing the stability and safety of the entire clamping device. Each limiting block 22 is installed between its corresponding pair of fixed posts 21, ensuring that the limiting block 22 can stably limit the movement range of the movable seat 3. By setting the limiting block 22 between every two fixed posts 21, precise limiting control of the movable seat 3 can be achieved. This arrangement helps prevent the movable seat 3 from deviating or exceeding the predetermined working area during operation.

[0040] It should be noted that the guide surface 23, located on the limiting block 22, is arc-shaped. This design helps to smoothly guide the stainless steel tube into the V-shaped clamping plate 9, reducing impact and wear during direct contact. The arc-shaped guide surface 23 provides a smooth transition path, thereby improving the operating comfort and service life of the entire clamping device.

[0041] It is worth noting that the guide surface 23 is designed with one side having a higher horizontal height than the opposite side. This design facilitates guiding the steel pipe into the V-shaped clamping plate 9. This design of the guide surface 23 ensures smoother and more accurate entry of the steel pipe into the V-shaped clamping plate 9. The lower side serves as the initial contact point, guiding the steel pipe to gradually rise along the curved surface to the clamping position of the V-shaped clamping plate 9. During the clamping process, the steel pipe first contacts the lower side of the guide surface 23 and then slides along the curved surface to the clamping position of the V-shaped clamping plate 9. This design helps reduce friction and collisions when the steel pipe enters the clamping position, improving clamping accuracy and efficiency. Due to the curved design and height difference of the guide surface 23, noise and vibration when the steel pipe approaches the V-shaped clamping plate 9 are reduced, thereby improving the operational comfort and service life of the entire clamping device.

[0042] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
