[0032] Please refer to Figures 2 to 5 As another object of the present application, the present application further provides a hydrogen storage tank inner container welding device, which comprises two clamping and rotating devices 10 and the infrared heating device 20 of any one of the above. The two clamping and rotating devices 10 clamp two hydrogen storage tank inner containers (not shown) respectively. The hydrogen storage tank inner containers are made of plastic. The hydrogen storage tank inner containers can be understood as one of two parts of a complete hydrogen storage tank inner container obtained by welding and are preferably half of the hydrogen storage tank inner container. In addition, the complete hydrogen storage tank inner container can also be obtained by welding three hydrogen storage tank inner containers. In this case, two hydrogen storage tank inner containers are first welded into a longer hydrogen storage tank inner container by the two clamping and rotating devices 10 respectively, and then the longer hydrogen storage tank inner container is clamped by one clamping and rotating device 10 and welded with another hydrogen storage tank inner container clamped by another clamping and rotating device 10 to obtain a complete hydrogen storage tank inner container. The same applies to the other cases. The heating and welding end faces of the two hydrogen storage tank inner containers are opposite to each other. The infrared heating assembly 22 is used for simultaneously heating the two heating and welding end faces and can move relative to the two clamping and rotating devices 10 under the driving of the moving motor 24. The clamping and rotating devices 10 correspondingly rotate the hydrogen storage tank inner containers subjected to heating. The two hydrogen storage tank inner containers can be welded into a complete hydrogen storage tank inner container. Thus, the hydrogen storage tank inner container welding device can obtain the beneficial effects brought by any one of the infrared heating devices 20, which will not be described herein again. The hydrogen storage tank inner container welding device has the advantages of good heating effect and high reliability for the hydrogen storage tank inner containers.

[0033] Please refer to Figures 3 to 5, specifically, the clamping and rotating device 10 comprises a support frame 11, which comprises a hollow support cylinder 111 and a support ring 112 protruding around the outer periphery of one end of the support cylinder 111, and the hydrogen storage tank inner containers are arranged in the support cylinder 111 at intervals; a plurality of clamping jaws 12 are arranged on the support ring 112 along the circumferential direction of the support ring 112 and can move radially along the support ring 112, the clamping jaws 12 have clamping surfaces 1211 facing the central axis of the support ring 112, and the clamping surface 1211 of each clamping jaw 12 is shaped to match the hydrogen storage tank inner container; a driving ring 13 is connected to the support ring 112; a driving mechanism 14 drives the driving ring 13 to rotate to drive each clamping jaw 12 to move close to or away from the central axis of the support ring 112 radially along the support ring 112; a rotating ring 17 is fixedly connected to the support cylinder 111; a rotating mechanism 18 drives the rotating ring 17 to rotate, so that the rotating ring 17 can drive the workpiece clamped by the clamping jaw to rotate around the central axis of the support ring 112. The outer ring of the rotating ring 17 is provided with a ring of driven gears 171. The rotating mechanism 18 comprises a rotating motor 181 and a driving gear 182, the driving gear 182 is engaged with the driven gear 171, and the rotating motor 181 drives the driving gear 182 to rotate to drive the support ring 112 to rotate, so that the plurality of clamping jaws 12 rotate synchronously with the support ring 112. The infrared heating assembly 22 is provided with two heating surfaces, when the two heating welding end surfaces receive heating, each clamping jaw 12 of the clamping and rotating device 10 completes the movement close, so that the clamping surface 1211 of each clamping jaw 12 forms a clamping surface for fitting an annular outer surface of a hydrogen storage tank inner container and clamping the hydrogen storage tank inner container. Since the heat emitted by the heating surface will diffuse upward, it is necessary to rotate the hydrogen storage tank inner container to receive heating so as to make the heating uniform, therefore the rotating motor 181 is used to drive the hydrogen storage tank inner container to rotate, and the infrared heating assembly 22 is driven by the moving motor 24 to move into the space between the two clamping and rotating devices 10 and simultaneously heat the two heating welding end surfaces, after the two heating welding end surfaces complete receiving heating, the infrared heating assembly 22 is driven by the moving motor 24 to move out of the space between the two clamping and rotating devices 10, the rotating motor 181 stops working, and the two heating welding end surfaces are pressed and welded together to obtain a complete hydrogen storage tank inner container. Therefore, the clamping and rotating device 10 not only clamps the cylindrical surface of the hydrogen storage tank inner container with different outer diameter values located therebetween through a plurality of clamping jaws 12 which can move close to or away from the central axis of the support ring 112 with high adaptability, but also the clamping surface 1211 of each clamping jaw 12 can form a ring-shaped clamping surface to correspondingly clamp the annular outer surface of the hydrogen storage tank inner container in multiple parts, thereby ensuring high stability of clamping the workpiece, and the rotating mechanism 18 is used to drive the rotating ring 17 to rotate to drive each clamping jaw 12 connected to the support cylinder 111 to rotate synchronously, thereby ensuring stable clamping and rotating of the hydrogen storage tank inner container, ensuring uniform heating of each hydrogen storage tank inner container, and thereby the quality of welding the two hydrogen storage tank inner containers together is high.

[0034] Please refer to Figure 4 Preferably, the end face of the other end of the support cylinder 111 is provided with a plurality of cylinder fixing holes 1111 arranged around the central axis of the support cylinder 111, and the rotating ring 17 is provided with a plurality of ring fixing holes (not shown) arranged around the central axis of the rotating ring 17, and each pair of cylinder fixing holes 1111 and ring fixing holes, for example, threaded holes, are fixedly connected with a fixing member such as a bolt, stud or the like. In this way, the support cylinder 111 is fixedly connected with the rotating ring 17 in the circumferential direction at the end, so that the support cylinder 111 and the support ring 112 can stably receive the rotating force from the rotating ring 17.

[0035] Please refer to Figures 3 to 5 Preferably, the clamping device 10 further comprises a plurality of guide and moving mechanisms 15 corresponding to the number of the clamping jaws 12, each clamping jaw 12 comprises a clamping plate 121 and a force transmission plate 122, the clamping plate 121 is provided with a clamping surface 1211, a pair of guide blocks 152 are fixedly arranged on the side of the support ring 112 opposite to the driving ring 13 in a spaced-apart and opposite manner, a sliding block 151 is fixedly arranged on the side of the force transmission plate 122 facing the support ring 112 and located between the pair of guide blocks 152, a cam follower 154 is connected with the sliding block 151, and a guide and moving groove 153 is arranged in the driving ring 13 and inclined with respect to the radial direction of the driving ring 13. The guide and moving mechanism 15 comprises the sliding block 151, the pair of guide blocks 152, the guide and moving groove 153 and the cam follower 154. The driving mechanism 14 comprises a driving cylinder 141, a driving gear 142, a rack 143, a mounting plate 144 and a fixing plate 145, the rack 143 is fixedly arranged on the fixing plate 145, the fixing plate 145 is fixedly arranged on the driving ring 13, the mounting plate 144 is fixedly arranged on the support ring 112, and the driving cylinder 141 is mounted on the mounting plate 144. The driving cylinder 141 is drivingly connected with the driving gear 142 and drives the driving gear 142 to rotate in the forward or reverse direction. The driving gear 142 drives the rack 143 to move, thereby driving the driving ring 13 to rotate in the forward or reverse direction, and in turn driving the cam follower 154 to slide in the guide and moving groove 153, thereby correspondingly moving each clamping jaw 12 closer to or farther away from the central axis of the support ring 112. When each clamping jaw 12 is moved closer, the clamping surface 1211 of each clamping jaw 12 clamps the inner container of the hydrogen storage tank. When each clamping jaw 12 is moved farther away, the complete inner container of the hydrogen storage tank clamped by each clamping jaw 12 can be released. Thus, for each clamping jaw 12, the circumferential force received by the driving ring 13 can be converted into a radial force on the guide blocks 152 by the cam follower 154, thereby achieving stable and reliable displacement of the clamping jaw 12 with respect to the radial direction of the inner container of the hydrogen storage tank. Moreover, the cam follower 154 can efficiently convert the circumferential force received from the driving ring 13 into a radial force on the guide blocks 152, thereby making the radial movement of the clamping jaw 12 more stable and accurate.

[0036] Please refer to Figure 5Preferably, the support ring 112 is provided with a pair of communicating stepped grooves 1121 facing the slider 151, the guide block 152 is correspondingly protruded above the stepped grooves 1121 to form a sliding groove 1122 between the guide block 152 and the stepped grooves 1121, and the slider 151 comprises a pair of protrusions 1511 opposite in the radial direction of the support ring 112, which are correspondingly matched with the sliding groove 1122. Since the cam follower 154 can efficiently convert the circumferential force received from the driving ring 13 into radial force acting on the guide block 152, and the protrusions 1511 of the slider 151 are matched with the sliding groove 1122, the displacement of the slider 151 is more stable and accurate, and thus the radial movement of the clamping jaw 12 is more stable and accurate.

[0037] Reference should be made to Figure 4 Preferably, the number of clamping jaws 12 is 2N, and N is a natural number greater than or equal to 4. In the present application, N is 4, i.e. the number of clamping jaws 12 is 8. By setting the number of clamping jaws 12 to be an even number greater than 8, the workpiece can obtain multiple uniform clamping forces in the circumferential direction, while avoiding damage caused by excessive clamping force on the workpiece due to too few clamping surfaces 1211. A transfer mechanism 16 is arranged between each of the N groups of guide displacement grooves formed by the driving ring 13 corresponding to every two adjacent and non-repeated guide displacement grooves 153, and the guide displacement groove groups and the transfer mechanisms 16 arranged therebetween are uniformly arranged in the circumferential direction of the driving ring 13. The transfer mechanism 16 comprises a guide groove 161, a guide column 162 and a limiting disc 163. The guide groove 161 is arranged in the driving ring 13 and extends in the radial direction of the driving ring 13. The guide column 162 is inserted into the guide groove 161 and connected to the support ring 112 and the limiting disc 163 at both ends, and the limiting disc 163 is in sliding abutment with the driving disc. Since multiple transfer mechanisms 16 are arranged, the rotation of the driving ring 13 relative to the support ring 112 is stable and will not be deflected, ensuring that each clamping jaw 12 reliably obtains the force applied by the cam follower 154 acting on the driving ring 13 when the driving ring 13 rotates.
