[0024] Specifically, the operation steps of the pressure container processing clamp provided in the embodiment are as follows: before placing the pressure container, the first moving seat 21 and the second moving seat 22 are moved by the first driving element 4, the first moving seat 21 and the second moving seat 22 drive the first support arm 23 and the second support arm 25 to rotate synchronously in the moving process, and the first support wheel 24 and the second support wheel 26 move close to or away from each other with the rotation of the first support arm 23 and the second support arm 25, so as to adjust the distance between the first support wheel 24 and the second support wheel 26 to be suitable for the diameter of the pressure container, and then the pressure container is placed on the support assembly 2 after the first support wheel 24 and the second support wheel 26 are adjusted in place, so that the pressure container can be kept stable on the pressure container processing clamp, and when the pressure container needs to be rotated, the lifting support 31 is driven to move in the vertical direction by the second driving element 5 until the driving wheel 32 is attached to the pressure container, and then the driving wheel 32 is driven to rotate by the third driving element 33, so that the pressure container can be rotated by the friction between the driving wheel 32 and the pressure container. The pressure container processing clamp provided in the embodiment can be suitable for pressure containers of various sizes and meet the production requirements of pressure containers of different sizes, and the operation is simple and the universality is strong.

[0025] As shown in Figure 1 and Figure 2 The base 1 is provided with a sliding groove 11, and the first moving seat 21 and the second moving seat 22 are movably arranged in the sliding groove 11. The sliding groove 11 is used to limit the moving direction of the first moving seat 21 and the second moving seat 22 on the base 1, so as to prevent the first moving seat 21 and the second moving seat 22 from deviating from the preset direction when moving, thereby improving the structural stability of the pressure container processing clamp.

[0026] In detail, the first driving member 4 comprises a first motor 41 and a driving rod 42 arranged at the output end of the first motor 41, the driving rod 42 is rotatably arranged on the base 1, and two thread parts 43 with opposite rotation directions are arranged on the driving rod 42, and the first moving seat 21 and the second moving seat 22 are respectively provided with first threaded holes matched with the thread parts 43. When the driving rod 42 rotates under the driving of the first motor 41, the first moving seat 21 and the second moving seat 22 can be driven to move along the axial direction of the driving rod 42 through the cooperation between the thread parts 43 and the first threaded holes, and the rotation directions of the two thread parts 43 on the driving rod 42 are opposite, so that the moving directions of the first moving seat 21 and the second moving seat 22 are opposite, thereby driving the first moving seat 21 and the second moving seat 22 to move close to or away from each other, and the positions of the first moving seat 21 and the second moving seat 22 on the base 1 can be locked through the cooperation between the thread parts 43 and the first threaded holes, so as to prevent the first moving seat 21 and / or the second moving seat 22 from moving unexpectedly during the processing, causing the first supporting wheel 24 and / or the second supporting wheel 26 to be separated from the pressure container, and ensuring that the position of the pressure container on the pressure container processing clamp remains stable during the processing.

[0027] Please refer to Figure 1 and Figure 2 , two supporting assemblies 2 are arranged on the base 1 in a spaced manner, and the two supporting assemblies 2 are respectively arranged close to the opposite ends of the base 1. Arranging two supporting assemblies 2 on the base 1 in a spaced manner can support the two ends of the pressure container respectively, which is beneficial to further improve the stability of the pressure container on the pressure container processing clamp and prevent the pressure container from tilting during the processing.

[0028] In the embodiment, a first connecting rod 6 is arranged between the two first supporting arms 23, and the two ends of the first connecting rod 6 are fixedly connected with the two first supporting arms 23 respectively, and a second connecting rod 7 is arranged between the two second supporting arms 25, and the two ends of the second connecting rod 7 are fixedly connected with the two second supporting arms 25 respectively. The first connecting rod 6 connects the two first supporting arms 23, and the second connecting rod 7 connects the two second supporting arms 25 between the two supporting assemblies 2, so that when the first moving seat 21 and the second moving seat 22 in one of the supporting assemblies 2 move under the driving of the first driving member 4, the first supporting arm 23 and the second supporting arm 25 in the two supporting assemblies 2 move synchronously, so that the first supporting wheel 24 and the second supporting wheel 26 in the two supporting assemblies 2 remain synchronous.

[0029] As Figure 1As shown, the base 1 is provided with a first guide rod 12, and the first moving seat 21 and the second moving seat 22 are respectively provided with a first guide hole matched with the first guide rod 12. The first guide rod 12 provided on the base 1 is used to cooperate with the first guide hole on the first moving seat 21 and the second moving seat 22, so as to prevent the first moving seat 21 and the second moving seat 22 from deviating from the preset direction, and keep the positions of the first moving seat 21 and the second moving seat 22 on the base 1 stable.

[0030] Please refer to Figure 3 The second driving member 5 includes a cylinder 51 and a piston rod 52 provided at the output end of the cylinder 51, and the end of the piston rod 52 away from the cylinder 51 is matched with the lifting support 31. The piston rod 52 is driven by the cylinder 51 to extend or retract the cylinder 51, so that the lifting support 31 is moved by the action of the piston rod 52. When the piston rod 52 extends out of the cylinder 51, the movable support rises, and when the piston rod 52 retracts into the cylinder 51, the movable support descends, so as to adjust the height of the lifting support 31 and move the driving wheel 32 to the position abutting against the pressure container.

[0031] Specifically, the lifting support 31 is provided with a vertical second guide rod 34, and the base 1 is provided with a second guide hole matched with the second guide rod 34. The second guide rod 34 cooperates with the second guide hole to guide the lifting support 31, so as to ensure that the lifting support 31 moves in the vertical direction and avoids tilting or deflection. The driving wheel 32 is stably abutted against the pressure container, which is beneficial to improve the reliability of the pressure container processing clamp.

[0032] As shown in Figure 2 and Figure 3 The driving wheel 32 is provided with a first sprocket 35, the third driving member 33 includes a second motor 36 and a second sprocket 37 provided at the output end of the second motor 36, and the first sprocket 35 and the second sprocket 37 are connected by a transmission chain 38. When the second sprocket 37 rotates under the drive of the second motor 36, the transmission chain 38 transmits the power output by the second motor 36 from the second sprocket 37 to the first sprocket 35, and at this time, the driving wheel 32 continuously rotates under the drive of the second motor 36 to drive the pressure container placed on the pressure container processing clamp to rotate.

[0033] Please refer to Figure 1 and Figure 2In the embodiment, a plurality of supporting legs 8 are arranged on the base 1 at intervals, each of the supporting legs 8 comprises a connecting adjusting screw 81 and a supporting pad 82, and the base 1 is provided with a second threaded hole matched with the adjusting screw 81. The supporting legs 8 are used to support the base 1, and the base 1 can be leveled by rotating the adjusting screw 81 to adjust the length of the adjusting screw 81 extending out of the second threaded hole, so as to avoid the pressure vessel from sliding off the supporting assembly 2 after being placed on the pressure vessel processing clamp due to the inclination of the base 1.

[0034] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
