DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0027] Embodiment one As Figures 1 to 3 , Figure 8As shown, the present application provides a connecting rod automatic welding device, which comprises a welding base 1; a plurality of welding machines 2 are arranged, and a plurality of welding machines 2 are arranged on each of the opposite side walls of the welding base 1; a material guiding assembly 3 is arranged on the welding base 1; a discharging assembly 4 is movably connected between the material guiding assembly 3; a welding table assembly 6 is arranged on the welding base 1, and the position of the discharging assembly 4 corresponds to the position of the welding table assembly 6; the material guiding assembly 3 comprises a material guiding seat 31 arranged on the welding base 1, a through slot 32 is arranged through the material guiding seat 31, and a material guiding frame 33 is arranged outside the two ends of the through slot 32; the discharging assembly 4 comprises a rotating motor 41 arranged on the material guiding seat 31, and a discharging claw 42 is arranged on the output shaft of the rotating motor 41; the welding table assembly 6 comprises a welding table seat 61 arranged on the welding base 1 away from the material guiding assembly 3, a turnover frame 62 is rotatably arranged on the welding table seat 61, and the discharging claw 42 is movably arranged through the turnover frame 62 away from the output shaft of the rotating motor 41.

[0028] First, the two connecting rods to be welded together are placed on the material guiding assembly 3 (i.e. the connecting rods are placed through the through slot 32, and at this time the two ends of the connecting rod in the length direction are located on the two material guiding frames 33) and the welding table assembly 6 (the connecting rod is located on the turnover frame 62, and the turnover frame 62 can be adjusted by rotating to make the connecting rod placed on the turnover frame 62 coaxial with the connecting rod placed in the through slot 32), at this time the two connecting rods are coaxial, and the welding work can be completed by the welding machines 2 (the welding machines 2 are prior art, so they will not be described here) at the corresponding positions between the two connecting rods; after welding is completed, the rotating motor 41 is started to drive the discharging claw 42 to rotate, and the welded connecting rod can be taken off from the turnover frame 62 by the discharging claw 42.

[0029] Example two On the basis of example one, as shown in Figures 1 to 2 , Figures 4 to 7 A connecting seat 321 is arranged in the through slot 32, the opposite ends of the connecting seat 321 are arranged through the outside of the through slot 32, and the material guiding frames 33 are arranged at the opposite ends of the connecting seat 321; the material guiding frame 33 comprises an arc-shaped frame 331 arranged on the connecting seat 321; a fixed pressing rod 332 is horizontally arranged in the arc-shaped opening of the arc-shaped frame 331; a pressing block 333 is movably arranged outside the fixed pressing rod 332; the pressing block 333 comprises a sliding sleeve 3331 movably arranged outside the fixed pressing rod 332; an adjusting rod 3332 is arranged on the outer circumferential wall of the sliding sleeve 3331; an arc-shaped pressing block 3333 is arranged at the end of the adjusting rod 3332 away from the sliding sleeve 3331, and the end of the arc-shaped pressing block 3333 away from the adjusting rod 3332 is in an arc-shaped structure; a plurality of clamping grooves 3334 are uniformly distributed on the inner circumferential wall of the arc-shaped opening of the arc-shaped frame 331 in the circumferential direction, and a clamping block 3335 is movably arranged in each clamping groove 3334.

[0030] Before welding, the connecting rod is placed in the through groove 32, so that both ends of the connecting rod in the length direction are located on the two guide frames 33 respectively (that is, both ends of the connecting rod in the length direction are located in the arc-shaped opening of the arc frame 331, which makes it easy for the connecting rod to maintain a stable position after placement; the position of the sliding sleeve 3331 can be adjusted by sliding outside the fixed pressure rod 332, and then the connecting rod placed in the arc-shaped opening of the arc frame 331 is pressed and fixed by the arc-shaped pressure block 3333; the adjusting rod 3332 can be located in the threaded rod structure, so that the distance between the sliding sleeve 3331 and the arc-shaped pressure block 3333 can be adjusted by rotating according to the connecting rod of different diameters, so that the arc-shaped opening of the arc-shaped pressure block 3333 can abut against the outer peripheral wall of the connecting rod.

[0031] Depending on the diameter of the connecting rod, a locking block 3335 can be installed in the corresponding slot 3334 (the outer peripheral wall of the locking block 3335 can be covered with an anti-slip layer) to facilitate the support of the connecting rod through the locking block 3335 and prevent the connecting rod from moving during the welding process.

[0032] Example 3 Based on Example 1, such as Figures 1 to 3 , Figure 8 As shown, a shaft 411 is coaxially mounted on the output shaft of the rotating motor 41. A feeding claw 42 is located at the end of the shaft 41 away from the rotating motor 41. The feeding claw 42 includes a claw seat 421, which is mounted on the outer peripheral wall of the shaft 411. Multiple feeding claws 422 are provided, and these claws are arranged in parallel and spaced apart at the end of the claw seat 421 away from the shaft 411. A notch 423 is located at the end of the feeding claw 422 away from the shaft 411. The tilting frame 62 includes a tilting motor 621, which is embedded in the top surface of the welding platform 61. The rotating frame 622 is mounted on the output shaft of the tilting motor 621; there are two adjusting motors 623, which are spaced apart on the top surface of the tilting frame 622; there are two tilting plates 624, one on the output shaft of each adjusting motor 623; there are multiple through slots 625, one on each tilting plate 624, and the positions of the through slots 625 correspond one-to-one with the positions of the material claws 422, with the material claws 422 moving through the corresponding through slots 625.

[0033] Before placing the connecting rod on the tilting frame 62, the starting motor 41 drives the shaft 411, the claw seat 421, and the material claw 422 to rotate, causing the material claw 422 to move through the corresponding through slot 625. At this time, when the connecting rod is placed between the two tilting plates 624, the outer peripheral wall of the connecting rod will not contact the material claw 422. After the connecting rod is placed between the two tilting plates 624, the starting motor 623 can also drive the tilting plates 624 to rotate, so that the included angle between the two tilting plates 624 can be adjusted according to the different diameters of the connecting rod, so that the connecting rod placed between the two tilting plates 624 and the connecting rod placed in the arc opening of the arc frame 331 are coaxial (that is, the diameter of the connecting rod placed between the two tilting plates 624 and the connecting rod placed in the arc opening of the arc frame 331 can be adjusted, which helps to maintain the positional accuracy of the two connecting rods after welding).

[0034] The opening distance of the notch 423 is greater than the diameter of the connecting rod, so that when the rotating motor 41 drives the shaft 411, the claw seat 421 and the material claw 422 to rotate, the connecting rod can be located inside the material claw 422. Under the rotation of the material claw 422, it can be taken out between the two flipping plates 624.

[0035] The included angle between the two flip plates 624 is between 30 and 60 degrees, which facilitates the adjustment of the height position of connecting rods of different diameters. This makes it easier for the connecting rod placed between the two flip plates 624 to be coaxial with the connecting rod placed in the arc-shaped opening of the arc frame 331.

[0036] When the material claw 422 is not in use (that is, by starting the rotating motor 41, the material claw 422 can be moved away from the through groove 625), after the connecting rod welding is completed, the flipping motor 621 is started to drive the flipping frame 622 to flip, so that the connecting rod between the two flipping plates 624 can complete the unloading.

[0037] Example 4 Based on Example 1, such as Figures 1 to 2 , Figure 4 As shown, a lifting cylinder 5 is provided on the side wall of the welding base 1 away from the welding table 61. A flipping seat 51 is rotatably provided on the piston rod of the lifting cylinder 5. A feeding cylinder 52 is provided on the flipping seat 51. The piston rod of the feeding cylinder 52 corresponds to the position of the arc frame 331. A pusher plate 53 is provided on the piston rod of the feeding cylinder 52.

[0038] Before welding, after the connecting rod is placed in the arc-shaped opening of the arc-shaped frame 331, the lifting cylinder 5 can be started to adjust the position of the turnover seat 51 in the vertical direction, so that the pushing disc 53 on the piston rod of the feeding cylinder 52 corresponds to the position of the connecting rod, the feeding cylinder 52 is started to push the pushing disc 53 (convenient for pushing the connecting rods of different diameters placed in the arc-shaped opening of the arc-shaped frame 331 through the pushing disc 53), so that the pushing disc 53 can push the connecting rod to move in the arc-shaped opening of the arc-shaped frame 331 for position adjustment (so that the connecting rod moves in the horizontal direction); or after the connecting rod is welded, the feeding cylinder 52 pushes the pushing disc 53, so that the pushing disc 53 can push the connecting rod to move, that is, the connecting rod located in the arc-shaped opening of the arc-shaped frame 331 moves to the position close to the two turnover plates 624, so as to facilitate the feeding cylinder 422 to complete the feeding.

[0039] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
