Description

Technical Field

[0001] This utility model relates to the technical field of spinning clamping mechanisms, specifically a spinning clamping device for processing large seamless gas cylinders. Background Technology

[0002] Seamless gas cylinders (large size) are key equipment for storing high-pressure gases (such as industrial gases, natural gas, hydrogen, etc.) and are widely used in energy, chemical, transportation, and medical fields. With technological advancements, gas cylinders are evolving towards larger volumes and higher pressures to meet increasing demands. These large gas cylinders (typically over 300mm in diameter, several meters or even tens of meters in length, and weighing several tons) require stable, reliable, and precise clamping and fixing at multiple stages of the manufacturing process (such as necking and spinning, mouth processing, hydrostatic testing, surface treatment, and winding) to ensure processing accuracy, operational safety, and product quality. Commonly used large seamless gas cylinder diameters are currently 559mm, 610mm, and 720mm, with each diameter corresponding to various length specifications. Currently, large seamless gas cylinders ranging from 2 to 12 meters in length are in use.

[0003] Currently, the clamping technology commonly used in the processing of large seamless gas cylinders has the following problems and shortcomings: Large seamless gas cylinders are generally fixed by spinning at both ends, but this method lacks support for the cylinder body, thus increasing the support strength of the spinning clamp. Although some manufacturers design multiple support mechanisms at the cylinder body, they are basically fixed support mechanisms. Once a large seamless gas cylinder of different length (referring to the same diameter) is replaced, the support position of the support mechanism is uneven, and there is still a problem of unstable support and fixation.

A horizontal plate 20 is fixedly mounted on the second connecting plate 11 and the third connecting plate 16 respectively. The bottom surface of the horizontal plate 20 is connected to the upper edge of the vertical plate 17 by a sliding assembly. Five support mechanisms are respectively mounted on the horizontal plate 20, and the clamping center points of the five support mechanisms are on the same straight line, which is in the same direction of movement as the support mechanism. A driving rotation mechanism and an auxiliary rotation mechanism are respectively mounted on both sides of the base plate 1. The driving rotation mechanism and the auxiliary rotation mechanism can axially fix both ends of the large seamless gas cylinder and drive the large seamless gas cylinder to rotate. The driving movement assembly includes a motor 13, a pair of lead screws 12 with opposite thread directions, a pair of lead nuts 10, and a pair of fixed seats 15. The motor 13 is a dual-output motor 13 and is fixedly mounted on the base plate 1. At the center, one end of a pair of lead screws 12 is connected to the two output ends of a motor 13, and the other end is rotatably connected to a fixed base 15.

A reinforcing plate 22 is fixedly provided between a pair of upright plates 17 and at both ends of the upper edge of the upright plate 17.

[0016] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows: According to the instruction manual Figure 1-4 As can be seen, during operation, the position of the support mechanism is adjusted according to the length of the large seamless gas cylinder to ensure the uniformity of the support and fixing positions and increase the stability of the support and fixing. The central support mechanism remains stationary, while the four support mechanisms on both sides of the center are close to the central support mechanism; this is the initial position. Since the large seamless gas cylinder is quite long, errors in the initial position and adjustment process can be ignored. During adjustment, the drive assembly moves the second connecting plate 11 outwards simultaneously, and the connecting rod 9 pushes the gear 5 on the mounting base 6 outwards. Since the gear 5 is meshed with the fixed rack 8 and the movable rack 2 respectively, and the movable plate 3 connected to the movable rack 2 is horizontally slidably connected to the horizontal sliding groove 19 on the side wall of the upright plate 17 via the slider 23, it can move the movable plate 3 outwards by twice the distance of the gear 5, i.e., twice the distance of the second connecting plate 11, thus ensuring that the five support mechanisms are in a uniformly distributed state (as explained above, errors in the initial position and adjustment process are ignored). For example: [Refer to...] Figure 1 and Figure 3 If the distance the two inner support mechanisms move is L, then the distance the two outer support mechanisms move is 2L (as explained above, assuming the initial position is at the center). That is, the distance between the outer and inner support mechanisms is L, and the distance between the inner and central support mechanisms is L. Therefore, the five support mechanisms are evenly distributed, ensuring uniformity and stability of the support. Finally, the driving rotation mechanism and auxiliary rotation mechanism can axially fix both ends of the large seamless gas cylinder and drive it to rotate for processing, such as surface treatment. This invention can support the body of a large seamless gas cylinder, and by adjusting the positions of the five support mechanisms, it ensures uniform and stable support. It is suitable for large seamless gas cylinders of different lengths, has strong applicability, allows for rapid adjustment, and improves work efficiency.

[0017] The drive and movement assembly includes a motor 13, a pair of lead screws 12 with opposite thread directions, a pair of lead nuts 10, and a pair of fixed seats 15. The motor 13 is a dual-output motor and is fixedly mounted at the center of the base plate 1. One end of each lead screw 12 is connected to one of the two output ends of the motor 13, and the other end is rotatably connected to the fixed seats 15. The fixed seats 15 are fixedly connected to the upper surface of the base plate 1. The pair of lead nuts 10 are screwed onto the lead screws 12 on both sides of the motor 13. A second connecting plate 11 is fixedly connected to the upper surface of the lead nuts 10. The drive and movement assembly has a simple structure, strong synchronization, small error, and improves the accuracy of adjustment. A protective cover 14 is provided on the outside of the motor 13 to protect the motor 13, and of course, to ensure good heat dissipation and normal operation of the motor 13.

[0018] The support mechanism includes a support plate 21, an arc-shaped support frame, and a pair of rotatable rollers. The arc-shaped support frame is fixedly mounted on the support plate, and the pair of rollers are located on both sides of the arc-shaped support frame. The rollers on the five support mechanisms can support the body of a large seamless gas cylinder. The structure is simple and easy to repair and maintain. The support mechanism in this application is prior art; as long as it can support the cylinder body, it is sufficient. The support mechanism shown in the attached drawings is a schematic diagram for ease of understanding and does not represent a specific structure.

[0019] The sliding component includes a slide rail 18 and a slide track 24. The slide rail 18 is provided with the upper end surface of the vertical plate 17, and the slide track 24 is opened on the lower bottom surface of the horizontal plate 20. The slide rail 18 and the slide track 24 are slidably connected to each other to increase the stability of the horizontal plate 20 during movement.

[0020] Among them, a reinforcing plate 22 is fixedly installed between a pair of upright plates 17 and at both ends of the upper edge of the upright plates 17 to increase the stability of the overall structure.

[0021] In this utility model, the driving rotation mechanism includes a driving support frame 25, a driving clamp 31, and a driving component 32. The horizontal adjustment component 26 can drive the driving support frame 25 to move and adjust. The driving support frame 25 supports the driving clamp 31 and the driving component 32. The driving component 32 drives the driving clamp 31 to rotate. The driving clamp 31 can clamp and fix one end of the large seamless gas cylinder. The auxiliary rotation mechanism includes a horizontal adjustment component 26, an auxiliary support frame 27, a turntable 28, a hydraulic cylinder 29, and an auxiliary clamp 30. The horizontal adjustment component 26 can drive the auxiliary support frame 27 to move and adjust. The auxiliary support frame 27 can support the turntable 28, the hydraulic cylinder 29, and the auxiliary clamp 30. The hydraulic cylinder 29 drives the turntable 28 and the auxiliary clamp 30 to move axially. The auxiliary clamp 30 can clamp and fix the other end of the large seamless gas cylinder. The turntable 28 ensures the rotation of the large seamless gas cylinder during operation. The working principle of the drive rotation mechanism and the auxiliary rotation mechanism is simple. It only requires axial fixation of the large seamless gas cylinder and driving its rotation. This is easy to understand for those skilled in the art and can be easily implemented with existing technology. The drive rotation mechanism and the auxiliary rotation mechanism in the attached drawings of the specification do not represent the actual structure, but are only for the convenience of understanding the solution.
