[0022] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0023] like Figures 1 to 5 As shown, an embodiment of the utility model provides a folding box end beam welding fixture, which is used to clamp the folding box end beam 100 when welding the folding box end beam 100, including a frame 1, a turntable 2 rotatably connected to the frame 1, and two positioning components 3 and two limit components 4 installed on the turntable 2.

[0024] like Figure 1 As shown, a reduction motor 6 is fixed at one end of the frame 1, specifically, the reduction motor 6 is fixed at the left end of the frame 1, the turntable 2 is located above the reduction motor 6 and connected to the reduction motor 6, and it rotates driven by the reduction motor 6.

[0025] like Figures 1 to 3 As shown, the two positioning assemblies 3 are respectively located at the left and right ends of the turntable 2, and each positioning assembly 3 includes a positioning seat 31 fixed to the top surface of the turntable 2, a stopper 32 connected to the positioning seat 31, and a guide block 33 connected to the top surface of the turntable 2. Specifically, the positioning seat 31 is fixed to the top surface of the turntable 2 by welding or bolts, and the upper end of the stopper 32 extends forward to form a stopper 321 located above the turntable 2. The stopper 321 blocks the bottom corner piece 101 of the folding box end beam body 100 to limit the upward movement of the folding box end beam body 100. In this embodiment, the stopper 32 is a stop rod. The two guide blocks 33 are respectively located outside an outer side wall of the two positioning seats 31 away from each other to limit the folding box end beam 100 in the length direction of the folding box end beam 100, which can prevent the folding box end beam 100 from tilting, thereby improving the positioning stability, and when clamping the folding box end beam 100, the folding box end beam 100 can be quickly aligned under the guidance of the two guide blocks 33, that is, fast clamping is achieved while improving the positioning stability, further improving work efficiency.

[0026] like Figure 2 As shown, specifically, the guide block 33 stops outside the bottom corner piece 101. In order to further improve the positioning accuracy and simplify the structure, each guide block 33 extends forward and its inner side wall extends outwardly to form a guide portion 331. When the folding box end beam body 100 is clamped, the folding box end beam body 100 is quickly aligned under the guidance of the guide portion 331 to achieve rapid clamping. Figure 5As shown, preferably, in order to facilitate assembly and extend service life, a guide seat 34 is fixed to the top surface of the turntable 2 by bolts outside the outer side walls of the two positioning seats 31 away from each other, and a guide block 33 is connected to the top surface of a guide seat 34 and the two are locked by bolts. Figure 4 As shown, in order to further improve the positioning accuracy, in another preferred embodiment, the guide seat 34 is threadedly connected with an adjusting screw 35, the adjusting screw 35 protrudes from the top surface of the guide seat 34 and extends upward, and the guide block 33 is connected to the adjusting screw 35 so that it can move in the up and down directions, so that the position can be adjusted in the up and down directions according to the size requirements of the folding box end beam body 100, so as to be suitable for clamping folding box end beam bodies 100 of different sizes. Figure 5 As shown, of course, in other embodiments, the adjustment screw 35 can be eliminated, and then a slide groove 341 is formed downwardly on the top surface of the guide seat 34, and the slide groove 341 extends along the front-to-back direction. A slider 332 is formed on the bottom surface of the guide block 33 that cooperates with the slide groove 341 so that it can slide in the front-to-back direction, so that the position of the guide block 33 can be adjusted according to the size requirements of the folding box end beam body 100, thereby expanding the scope of use.

[0027] like Figure 1 , Figure 2 As shown, a limit assembly 4 is located in front of a positioning assembly 3 and includes a limit seat 41 located in front of the guide block 33 and fixed on the top surface of the turntable 2 and a limit pin 42 connected to the limit seat 41. The limit pin 42 is arranged along the length direction of the turntable 2 and can be extended and retracted in the inner and outer directions. Specifically, the outer wall of the limit seat 41 is provided with a threaded hole penetrating the limit seat 41, and the limit pin 42 is threadedly connected in the threaded hole so that it can move inward and outward, so that its position can be adjusted in the inner and outer directions, and the outer end of the limit pin 42 passes through the threaded hole outward, and the inner end of the limit pin 42 passes through the threaded hole inward. More specifically, the limit pin 42 is located on the outer side of the inner side wall of the guide block 33 and an operating part 421 located on the outer side of the limit seat 41 is fixed to its outer end. The operating part 421 extends upward. When the folding box end beam body 100 is clamped, the operating part 421 rotates to drive the limit pin 42 to rotate, so that the limit pin 42 moves inward to the end of the folding box end beam body 100.

[0028] like Figure 3 As shown, a clamping assembly 5 is provided on the front side of the turntable 2 corresponding to each positioning assembly 3. The clamping assembly 5 includes a clamping seat 51 fixed to the front side of the turntable 2 by bolts or welding and a connecting screw 52 threadedly connected to the clamping seat 51 in the front-to-back direction. A pressing plate 53 is connected to the front end of the connecting screw 52. A pressing plate 53 corresponds to a positioning seat 31. When the folding box end beam body 100 is clamped, the connecting screw 52 rotates to drive the pressing plate 53 to move backward to clamp the folding box end beam body 100, thereby preventing the folding box end beam body 100 from moving forward.

[0029] The two positioning components of the folding box end beam welding fixture of the utility model are provided with a guide block outside an outer side wall of the two positioning seats that are far away from each other. The two guide blocks limit the folding box end beam in the length direction of the folding box end beam, which can prevent the folding box end beam from tilting, thereby improving the positioning stability. When clamping the folding box end beam, the folding box end beam can be quickly aligned under the guidance of the two guide blocks, that is, fast clamping is achieved while improving the positioning stability, further improving the work efficiency. The folding box end beam welding fixture of the utility model has the characteristics of simple structure, high positioning stability and quick clamping.
