[0025] In one embodiment, Figure 1-Figure 4As shown, a device for splicing and fixing leftover materials of building aluminum formwork comprises a main rod column 100 and two fixed frames 200, wherein the main rod column 100 is provided with two mounting sleeves 900 rotatably connected thereto, and the side walls of the two fixed frames 200 are respectively fixedly connected to the two mounting sleeves 900 through support arm rods 400; each fixed frame 200 is provided with a fixing unit 600 and a centering mechanism, wherein the centering mechanism comprises two groups of side pressure centering components 300 respectively arranged on the side walls of the fixed frame 200, the two groups of side pressure centering components 300 correspond to each other and the side pressure centering components 300 are elastically damped and rotatably matched with the outer wall of the fixed frame 200, one end of the side pressure centering component 300 extends to the inner side of the fixed frame 200 and the side pressure centering component The lower end of 300 extends to the bottom of the fixed frame 200, the fixing unit 600 is arranged at the end of the fixed frame 200 facing the welding position and the fixing unit 600 is used to press the aluminum formwork scraps in the fixed frame 200 from the top; an angle adjustment unit 500 is arranged on the main rod column 100 and the angle adjustment unit 500 is connected to both support arms 400, the angle adjustment unit 500 can drive the two support arms 400 to rotate synchronously around the center of the main rod column 100 and the rotation directions of the two support arms 400 are opposite; it also includes a positioning baffle assembly 700, one end of the positioning baffle assembly 700 is connected to the top of the main rod column 100 and the other end extends to the center position between the two fixed frames 200.

[0026] In the embodiment of the present invention, when splicing two aluminum formwork scraps, the two aluminum formwork scraps are respectively placed inside the two fixed frames 200. The aluminum formwork scraps are in the center line position of the fixed frame 200 under the action of the two sets of side pressure centering components 300. The aluminum formwork scraps are pushed and moved toward the positioning baffle assembly 700. When the welding end of the aluminum formwork scraps contacts the side of the end portion between the two fixed frames 200 with the positioning baffle assembly 700, the pushing of the aluminum formwork scraps is stopped. When the welding ends of the two aluminum formwork scraps are in contact with the positioning baffle assembly 700, the welder can fix the aluminum formwork scraps through the fixing unit 600, operate the part where the positioning baffle assembly 700 is connected to the top of the main rod column 100, and withdraw the positioning baffle assembly 700 from between the two fixed frames 200. The ends of the two aluminum formwork scraps are in relative positions and the gap is very small. The welder can connect the two aluminum formworks by welding rods or the like. The ends of the plate scraps are welded together; after welding, the finished product can be pulled out from one end of one of the fixed frames 200; when the ends of the two aluminum template scraps are welded together at a certain angle, according to the angle of the beveled end of the aluminum template corner, the two support arm rods 400 are driven to rotate synchronously through the angle adjustment unit 500, and the two support arm rods 400 respectively drive the two corresponding fixed frames 200 to rotate, and then the two fixed frames 200 rotate a certain angle, the aluminum template scraps are placed on the fixed frame 200 and pushed toward the positioning baffle assembly 700. Since the ends of the scraps are beveled, the welding end of the aluminum template scraps is in face-to-face contact with the side of the positioning baffle assembly 700, so that the two aluminum template scraps can be accurately moved to the welding position, and then fixed and welded, effectively ensuring the accuracy and quality of welding; wherein, the bottom of the main rod column 100 can be fixed to the welding device through the chassis part 800.

[0027] In one embodiment, Figure 1-Figure 4As shown, the angle adjustment unit 500 includes an outer extension frame 510, an adjustment screw rod portion 520, an adjustment movable seat 540 and two connecting arms 560. The outer extension frame 510 is located on a side of the main rod column 100 away from the fixed frame 200 and one end of the outer extension frame 510 is fixedly connected to the main rod column 100.

It is hinged and the other end is rotatably connected to the corresponding connecting column 550; in the embodiment of the present invention, when it is necessary to adjust the relative angle of the two fixed frames 200, the welding personnel drives the adjusting screw rod part 520 to rotate by adjusting the operating end 530, and the adjusting screw rod part 520 is spirally matched with the adjusting movable seat 540 to make the adjusting movable seat 540 move along the outer extension frame 510, and the adjusting movable seat 540 can push and pull the corresponding two support arm rods 400 through two connecting arms 560. Under the action of the connecting arms 560, the two support arm rods 400 can rotate synchronously around the center of the main rod column 100 and the rotation directions are opposite. The two support arm rods 400 drive the corresponding fixed frame 200 to rotate, and then the angle between the two fixed frames 200 can be adjusted to adapt to the splicing angle of the two aluminum formwork scraps.

[0028] In one embodiment, Figure 1-Figure 3 As shown, the side pressure centering assembly 300 includes a centering rotating part 310 and a centering roller body 320. The centering rotating part 310 is rotatably arranged on the outer wall of the fixed frame 200 through the outer extension seat 210.

The centering mechanism also includes an elastic damping assembly 330, which is arranged at the bottom of the fixed frame 200 and the bottom of multiple centering rotating parts 310. All parts are connected to the elastic damping component 330; in the embodiment of the present invention, when the aluminum formwork scraps are inside the fixed frame 200, the centering roller bodies 320 in the two groups of side pressure centering components 300 are in contact with the side walls of the aluminum formwork scraps. Since the multiple centering rotating parts 310 are connected to the same elastic damping component 330, the two groups of centering rotating parts 310 rotate synchronously, but the rotation directions of the centering rotating parts 310 in different groups are opposite. Therefore, the multiple centering roller bodies 320 have a driving force on the side walls of the aluminum formwork scraps and the driving force is the same, so the aluminum formwork scraps can be pushed to the centerline position of the fixed frame 200.

[0029] In one embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the centering rotating part 310 includes a centering shaft 311, an upper centering arm 312 and a lower connecting arm 313, the centering shaft 311 is located at the side of the fixed frame 200 and the centering shaft 311 is rotatably connected to the outer extension seat 210, the upper centering arm 312 is located at the upper side of the fixed frame 200 and one end of the upper centering arm 312 is fixedly connected to the top of the centering shaft 311, and the other end of the upper centering arm 312 is inclined toward the fixed unit 600; the centering roller body 320 is rotatably connected to the end of the upper centering arm 312 away from the centering shaft 311; the One end of the lower connecting arm 313 is fixedly connected to the centering shaft 311 and the other end is connected to the elastic damping assembly 330; in the embodiment of the present invention, the elastic damping assembly 330 can act on multiple lower connecting arms 313 so that the multiple centering shafts 311 can maintain synchronous rotation, and the centering shaft 311 acts on the centering roller body 320 through the upper centering arm 312, thereby ensuring that the multiple centering roller bodies 320 maintain the same lateral pressure on the side wall of the aluminum template scrap. Since the upper centering arm 312 points to the fixed unit 600 and moves along the aluminum template scrap, it is convenient to push the aluminum template scrap.

[0030] In one embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a guide rod 340 is provided at the midline position of the bottom of the fixed frame 200, and the two ends of the guide rod 340 are connected to the bottom wall of the fixed frame 200 through a fixed seat, the lower connecting arm 313 is a telescopic rod, and the elastic damping component 330 includes a movable sleeve portion 331 and a plurality of connecting seats 332, the movable sleeve portion 331 is slidably sleeved on the guide rod 340, and the two ends of the movable sleeve portion 331 are connected to the fixed seat through a damping spring 350, and the plurality of connecting seats 332 are all provided on the outer wall of the movable sleeve portion 331, and the connecting seats 332 are connected to the end of the corresponding lower connecting arm 313 away from the centering rotating shaft 311; a semicircular ring 333 connected to the outer wall of the movable sleeve portion 331 through a rotating ring is also provided, and a plurality of equally spaced limiting teeth 220 are provided on the lower surface of the fixed frame 200, and the semicircular ring 333 can be stuck between two limiting teeth 220 In the embodiment of the present invention, when the centering roller body 320 is acted upon by the side of the aluminum template scrap, the centering roller body 320 acts on the upper centering support arm 312 and causes the centering rotating shaft 311 to rotate, and the lower connecting support arm 313 rotates with the centering rotating shaft 311 and acts on the movable sleeve part 331 to move on the guide rod 340. Due to the elastic action of the damping springs 350 at both ends of the movable sleeve part 331, the movable sleeve part 331 is subjected to the elastic damping action from the damping spring 350, so that the centering roller body 320 can always maintain the side pressure on the side wall of the aluminum template scrap; at the same time, the rotating ring is rotated, and the semicircular ring 333 is rotated to the side facing the fixed frame body 200, and the semicircular ring 333 can be correspondingly inserted between the two limiting tooth bodies 220, so that the semicircular ring 333 can limit the movement of the movable sleeve part 331, thereby ensuring that the centering roller body 320 firmly clamps the aluminum template scrap.

[0031] In one embodiment, Figure 1 and Figure 2 As shown, the fixing unit 600 includes an upper frame 610 detachably mounted on the fixing frame 200 and a fixing screw 620 arranged on the upper frame 610, the fixing screw 620 and the upper frame 610 are spirally rotated to cooperate, a clamping block 530 is arranged at the bottom end of the fixing screw 620, and a clamping handwheel portion 640 is arranged at the top of the fixing screw 620; in the embodiment of the present invention, when the top end of the aluminum formwork scrap contacts the side of the positioning baffle assembly 700, the welding personnel drives the fixing screw 620 to rotate through the clamping handwheel portion 640, and the rotating fixing screw 620 moves the clamping block 530 downward by cooperating with the upper frame 610, and the clamping block 530 gradually presses on the aluminum formwork scrap and fixes it, so as to avoid driving the aluminum formwork scrap when the positioning baffle assembly 700 is withdrawn.

[0032] In one embodiment, Figure 1-Figure 5As shown, the positioning baffle assembly 700 includes a positioning piece 710, an upper support 720 and a positioning shaft 730, wherein the upper support 720 is fixed to the top of the main pole column 100 and the positioning shaft 730 is rotatably arranged on the upper support 720, and one end of the positioning shaft 730 is connected to a positioning motor 740; the positioning piece 710 is located between the two fixed frames 200 and in the middle position, and a positioning support rod 750 is fixedly connected to one side of the positioning piece 710, and the end of the positioning support rod 750 away from the positioning piece 710 is connected to the positioning shaft 730, and the positioning piece 710 is connected to the positioning shaft 730.
