[0029] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0030] like Figure 1-7 As shown, a coaxiality fine-tuning bracket structure for flash butt welding workpieces includes a base 1. The left and right sides of the base 1 are respectively fixedly connected to the left and right ends of two limiting rods 2. Both limiting rods 2 are slidably connected to a mounting seat 12 with two limiting holes inside. A fine-tuning component 7 is provided at the upper end of the mounting seat 12. Another fine-tuning component 7 is provided on the left side of the fine-tuning component 7. The lower end of the other fine-tuning component 7 is fixedly connected to the upper end of the base 1. A workpiece fixing component 6 is provided at the upper end of both fine-tuning components 7. The two workpiece fixing components 6 can conveniently achieve the clamping and fixing effect of two workpieces to be butt welded. The two fine-tuning components 7 can drive the two workpiece fixing components 6 to rotate at a certain angle, thereby achieving the effect of synchronously rotating and fine-tuning the two workpieces to be butt welded, which is convenient for welding the two workpieces.

[0031] Both fine-tuning components 7 are movably connected to the rotating rod 3, which is equipped with four guide blocks. Circular turntables 14 are fixedly connected to both ends of the rotating rod 3. The two circular turntables 14 are movably connected to the two fine-tuning components 7 respectively through push-pull rods set at their relatively far ends. A meshing gear 8 is fixedly fixed on the left side of the rotating rod 3. The meshing gear 8 meshes with a meshing toothed plate 9. A support slide plate 10 is fixedly connected to the lower end of the meshing toothed plate 9. An electric push rod body 15 is fixedly connected to the front end of the support slide plate 10. The electric push rod body 15 drives the support slide plate 10 to move backward. With the cooperation of the meshing toothed plate 9 and the meshing gear 8, the rotating rod 3 can be rotated. The rotation of the rotating rod 3, with the cooperation of the circular turntables 14, the fine-tuning components 7, and the workpiece fixing components 6, can achieve the effect of rotating and fine-tuning the workpiece to be welded, facilitating the welding of the two workpieces.

[0032] Furthermore, the support slide plate 10 is slidably connected to two limiting rods 11 through two limiting holes inside it. The front and rear ends of the two limiting rods 11 are respectively fixedly connected to the relatively close ends of the two fixing plates 5. The two fixing plates 5 are fixedly connected to the upper end of the base 1. The front fixing plate 5 is fixedly connected to the front end of the electric push rod body 15. The electric push rod body 13 is fixedly installed on the right end of the base 1. The left end of the electric push rod body 13 is fixedly connected to the mounting seat 12. Two L-shaped brackets 4 are movably connected to the rotating rod 3. The lower ends of the two L-shaped brackets 4 are fixedly connected to the base 1. The fixed plates 5 and the limiting rods 11 can restrict the movement direction of the support slide plate 10. The electric push rod body 13 drives the mounting seat 12 to slide to the left, which in turn drives the right micro-adjustment component 7 to move to the left. At this time, with the cooperation of the corresponding workpiece fixing component 6, the right workpiece to be welded can be moved to the left, thereby realizing the docking process with the left workpiece to be welded.

[0033] Furthermore, both fine-tuning components 7 include support frames 71. The lower end of the left support frame 71 is fixedly connected to the upper end of the base 1, and the lower end of the right support frame 71 is fixedly connected to the upper end of the mounting base 12. A transmission sleeve 73 is movably connected to the lower side of each support frame 71. Each transmission sleeve 73 is movably connected to a rotating rod 3 with four guide blocks on it via two guide grooves inside. Two concave rods 74 are fixedly connected to the relatively far sides of each support frame 71. The four concave rods 74 are movably connected to two push-pull frames 72, each with two sliding through holes inside. Each push-pull frame 72 is movably connected to two circular turntables 14 with push-pull rods on their relatively far ends via push-pull grooves inside. A meshing toothed plate 75 is fixedly connected to the upper end of each push-pull frame 72. The two meshing toothed plates 75 mesh with two meshing gears 76. The gear 76 is fixedly connected to two hollow tubes 77, which are movably connected to the upper ends of two support frames 71. The relatively close ends of the two hollow tubes 77 are fixedly connected to two workpiece fixing components 6. The concave rod 74 restricts the movement direction of the push-pull frame 72. The rotation of the two circular turntables 14, with push-pull rods on them, pushes the two corresponding push-pull frames 72 forward. During the forward movement of the two push-pull frames 72, the meshing toothed plate 75 and the gear 76 work together to drive the two hollow tubes 77 to rotate synchronously. At this time, the two workpiece fixing components 6 work together to drive the two workpieces to be welded to rotate synchronously, thereby achieving the effect of fine-tuning the rotation angle of the two workpieces to be welded, which facilitates the welding process of the two workpieces.

[0034] Both workpiece fixing assemblies 6 include fixing frames 61. The two fixing frames 61 are fixedly connected to the relatively close ends of the two hollow tubes 77, respectively. Synchronous electric telescopic rod bodies 65 are fixedly installed at the upper and lower ends of the two fixing frames 61. Mounting frames 64 are fixedly connected to the relatively close ends of the four synchronous electric telescopic rod bodies 65. Workpiece fixing clamps 63 are provided at the relatively close ends of the four mounting frames 64. The four mounting frames 64 are slidably connected to four concave rods 62 through two sliding through holes opened inside them. The four concave rods 62 are divided into two groups, and their relatively close ends are fixedly connected to the front and rear sides of the two fixing frames 61, respectively. By activating the four synchronous electric telescopic rod bodies 65, the two corresponding mounting frames 64 on the upper and lower sides move closer to each other. With the cooperation of the workpiece fixing clamps 63, the two workpieces to be welded can be clamped and fixed. The concave rods 62 can limit the movement direction of the mounting frames 64.

[0035] The working principle of this utility model is as follows:

[0036] When using this device to fix two workpieces to be butt-welded, firstly, the welding ends of the two workpieces are passed through the inside of the two hollow tubes 77 and exposed to a suitable length. Then, the four synchronous electric telescopic rod bodies 65 are activated to move the four mounting brackets 64 closer together. With the cooperation of the four workpiece fixing clamps 63, the two workpieces to be butt-welded can be clamped and fixed on the relatively close side. Next, the electric push rod body 13 is activated to move the mounting base 12 to the left. With the cooperation of the fine adjustment component 7 and the workpiece fixing component 6 on the right side, the workpiece to be butt-welded on the right side can be moved to the left, thereby achieving the butt-welding process of the two workpieces. At this time, the two workpieces can be welded. During the welding process, when it is necessary to rotate and fine-tune the two workpieces to facilitate welding, the electric push rod body 15 is activated to drive the support slide plate 10 to move backward. Then, with the cooperation of the meshing gear 8 and the meshing toothed plate 9, the rotating rod 3 can be rotated. The rotation of the rotating rod 3 drives the two circular turntables 14 to rotate. Then, with the push-pull rods set on both circular turntables 14, the two push-pull frames 72 can be pushed forward. At this time, with the cooperation of the meshing gear 76, the meshing toothed plate 75 and the hollow tube 77, the two workpiece fixing components 6 can be rotated, thereby achieving the rotation and fine-tuning process of the two workpieces to facilitate welding.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
