DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, a welding device for a graphene heating tube comprises an operating frame 1, a motor 2 is fixedly connected to the right upper end of a horizontal portion of the operating frame 1, a bidirectional threaded rod 21 is fixedly connected to the output end of the motor 2, a guide rail 11 is symmetrically fixedly connected to the middle upper end of the horizontal portion of the operating frame 1, two guide rails 11 are close to each other and are slidably connected to a plurality of sliders 3, a fixed column 31 is fixedly connected to the upper end of the slider 3, a circular arc baffle 311 is symmetrically fixedly connected to the middle upper end of the fixed column 31, two circular arc baffles 311 are slidably connected to a fixing mechanism 5 close to each other, a rotating mechanism 6 is symmetrically fixedly connected to the upper end of the fixed column 31, a transmission mechanism 4 is fixedly connected to the right side of the rotating mechanism 6, and a welding mechanism 7 is fixedly connected to the middle upper end of the horizontal portion of the operating frame 1.

[0026] For details, see Figure 3 and Figure 4 The fixing mechanism 5 includes an arc bottom plate 53, the upper end of the arc bottom plate 53 is rotatably connected to an arc top plate 57, the front end of the outer surface of the arc top plate 57 is symmetrically fixedly connected to a snap spring piece, the front end of the outer surface of the arc bottom plate 53 is symmetrically fixedly connected to a slot 52, and the two snap spring pieces are both snapped into the corresponding slot 52.

[0027] The connection between the slot 52 and the snap spring piece mentioned above belongs to the conventional design in the prior art. In this solution, the slot 52 is connected to the snap spring piece. At the same time, the snap spring piece is elastic and can be deformed and separated from the slot 52 under the action of external force, thereby realizing that the arc bottom plate 53 and the arc top plate 57 on the same side can be rotated open.

[0028] The lower surface of the arc bottom plate 53 is fixedly connected with an arc rack 1 54 , the outer surface of the arc top plate 57 is fixedly connected with an arc rack 2 56 , and the inner surfaces of the arc top plate 57 and the arc bottom plate 53 are both fixedly connected with a plurality of clamping mechanisms 55 in a circular array.

[0029] The arc rack 1 54 and the arc rack 2 56 mentioned above can form a complete outer gear ring when the slot 52 is connected with the buckle spring piece, and can mesh with the gear 65 during the operation of the device.

[0030] The clamping mechanism 55 comprises an arc plate 552 , and two springs 551 are fixedly connected to the lower surface of the arc plate 552 . One end of the two springs 551 away from the arc plate 552 is fixedly connected to the arc bottom plate 53 and the arc top plate 57 , respectively.

[0031] The material and structure of the spring 551 described in this solution do not need to be specifically limited, and it only needs to work normally and be reused.

[0032] Specifically, before welding the graphene heating tube, the user presses the two snap springs inward to separate them from the slot 52, then opens the arc top plate 56 and the arc rack 2 57, places the graphene heating tube to be welded on the inner surface of the arc plate 552, then closes the arc top plate 56 and the arc rack 2 57, and then the graphene heating tube to be welded is tightly fixed on the inner surfaces of several arc plates 552 through the cooperation between the snap springs and the slot 52 and the cooperation between the spring 551 and the arc plate 552.

[0033] For details, see Figure 4 The rotating mechanism 6 includes a fixed rod 61, the upper end of the fixed rod 61 is rotatably connected to a limit ring 62, the inner cavity of the limit ring 62 is slidably connected to a rotating rod 63, the outer surface of the rotating rod 63 is slidably connected to a gear 65, the gear 65 is meshed with the arc rack 54, and fixed plates 64 are fixedly connected on both sides of the gear 65, and the bottom ends of the two fixed plates 64 are fixedly connected to the top of the fixed column 31.

[0034] The shape of the rotating rod 63 in the above-mentioned embodiment is a circular roller with four protrusions in an annular array on the outer surface. At the same time, the corresponding inner cavities of the limiting ring 62 and the gear 65 are circular and have four grooves in an array, that is, the protrusions on the rotating rod 63 can slide on the inner walls of the grooves of the limiting ring 62 and the gear 65, and the grooves also limit the position of the protrusions so that they do not shift.

[0035] That is, during the operation of the device described in this scheme, the fixing mechanism 5, the fixing plate 64 and the gear 65 can slide along the rotating rod 63, and when the rotating rod 63 is driven to rotate, the limit ring 62 and the gear 65 can rotate through the cooperation of the protrusion and the groove to realize the subsequent operation of the device.

[0036] Furthermore, the user ensures that the graphene heating tube to be welded is fixed by the fixing mechanism 5, wherein the two gears 65 can jointly mesh with the arc rack 1 54 or the arc rack 2 56.

[0037] After the motor 2 rotates, it drives the bidirectional threaded rod 21 to rotate, driving the slider 3 threadedly connected to it, so that the slider 3 approaches the welding mechanism 7 along the guide rail 11. The slider 3 moves, driving the fixed column 31 to move, so that the fixing mechanism 5 and the gear 65 and the fixed plate 64 move at the same time. At the same time, since the bottom end of the fixing rod 61 is fixedly connected to the upper end of the guide rail 11, when the slider 3 moves and drives the fixed column 31 to move, the transmission mechanism 4 and the fixing rod 61, the limit ring 62 and the rotating rod 63 remain in position.

[0038] For details, see Figure 2 , Figure 3 and Figure 4The transmission mechanism 4 includes a driving wheel 42 and a driven wheel 44. The inner cavity of the driving wheel 42 is fixedly connected with a driving shaft, and the left end of the driving shaft is fixedly connected to the right end of the corresponding rotating rod 63.

[0039] The right end of the driving shaft is fixedly connected with a handle 41 , the inner cavity of the driven wheel 44 is fixedly connected with the driven shaft, the left end of the driven shaft is fixedly connected with the right end of the corresponding rotating rod 63 , and the driving wheel 42 and the driven wheel 44 are wound together with the connecting belt 43 .

[0040] Furthermore, when the entire device is excited, the motor 2 rotates, driving the bidirectional threaded rod 21 to rotate, so that several fixed columns 31 move closer to the welding mechanism 7, driving the graphene heating tube to be welded. During the welding process, the user turns the handle 41, so that the driving shaft drives the driving wheel 42 to rotate, and then the driven wheel 44 and the belt 43 are driven by the driving wheel 42 to rotate, so that the driven shaft and the driving shaft rotate in the same direction.

[0041] Furthermore, the rotating rod 63 fixedly connected to the driving shaft and the driven shaft will rotate. Due to the shape of the rotating rod 63, the gear 65 will be driven to rotate, and the arc rack 1 54 and the arc rack 2 56 meshing with the gear 65 will be driven to rotate, so that the entire fixing mechanism 5 rotates and slides along the arc baffle 311, thereby welding different positions of different graphene heating tubes.

[0042] For details, see Figure 5 The welding mechanism 7 includes two welding brackets 72 , and the two welding brackets 72 are fixedly connected with an arc welding nozzle 73 on one side close to each other, and a welding power source 71 is fixedly connected to the front end of the outer surface of the arc welding nozzle 73 .

[0043] Furthermore, in the present solution, when the device is activated, the user turns on the welding power source 71 and the arc welding nozzle 73, and waits for the graphene heating tube to be welded to approach.

[0044] The welding power source 71 and the arc welding nozzle 73 described in the above-mentioned embodiment are both prior art;

[0045] During the implementation process, the welding power source 71 mentioned above generally uses a mixture of oxygen, acetylene and other gases to ignite and heat the graphene tube for welding, and the position where the high-temperature flame is ejected is the arc welding nozzle 73 in this scheme. Then, the connection of the graphene tube is quickly heated by a plurality of arc welding nozzles 73.

[0046] It should be noted that the specific installation method of the motor 2, the circuit connection method and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.

[0047] The working principle of the utility model is:

[0048] When the device described in this scheme is not activated, the user squeezes the snap spring pieces on both sides of the arc rack 56 inward to unlock it from the corresponding slot 52, and then the user lifts up the arc top plate 57, wherein the arc top plate 57 is rotatably connected to the arc bottom plate 53 through the hinge 51, and the user places the graphene heating tube to be welded on the inner surface of the arc plate 552, and then rotates the arc top plate 57 to make several arc plates 552 fixedly connected to the arc top plate 57 contact with the surface of the graphene heating tube, and then the snap spring pieces are locked with the slot 52, and the overall clamping mechanism 55 fixes the graphene heating tube to be welded.

[0049] The user excites the motor 2 and the welding mechanism 7. After the motor 2 rotates, it drives the bidirectional threaded rod 21 to rotate, and drives the slider 3 threadedly connected thereto, so that the slider 3 approaches the welding mechanism 7 along the guide rail 11. The slider 3 moves, driving the fixed column 31 to move, so that the fixing mechanism 5 and the gear 65 and the fixed plate 64 move at the same time, and the graphene heating tube to be welded moves to above the arc-shaped welding nozzle 73. At the same time, since the bottom end of the fixed rod 61 is fixedly connected to the upper end of the guide rail 11, when the slider 3 moves and drives the fixed column 31 to move, the transmission mechanism 4 and the fixed rod 61, the limit ring 62 and the rotating rod 63 remain in position.

[0050] During the welding process, the user rotates the handle 41, so that the driving shaft drives the driving wheel 42 to rotate, and then the driven wheel 44 and the belt 43 are driven by the driving wheel 42 to rotate, so that the driven shaft and the driving shaft rotate in the same direction.

[0051] Furthermore, the rotating rod 63 fixedly connected to the driving shaft and the driven shaft will rotate. Due to the shape of the rotating rod 63, the gear 65 will be driven to rotate, and the arc rack 1 54 and the arc rack 2 56 meshing with the gear 65 will be driven to rotate, so that the entire fixing mechanism 5 rotates and slides along the arc baffle 311, thereby welding different positions of different graphene heating tubes.

[0052] After the welding is completed, the user suspends the working state of the welding mechanism 7 and the motor 2, squeezes the buckle spring piece inward to unlock it from the slot 52, then removes the welded graphene heating tube, and then resets each mechanism component through the motor 2, waiting for the next welding work.

[0053] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
