[0027] The present invention will be further described below in conjunction with the accompanying drawings:

[0028] like Figure 1 — Figure 3 As shown, the present embodiment provides a crawler support wheel welding machine, including a welding rotation system 1 and a welding system 2. The welding system 2 is installed on the side of the welding rotation system 1. The welding rotation system 1 is used to clamp the supporting wheel blank and drive the supporting wheel blank to rotate. The welding system 2 includes a welding frame 21, a transverse movement device 22, a wire feeding device 23, a welding gun 24 and a swing control device 25. The transverse movement device 22 is installed on the welding frame 21, and the welding gun 24 is installed on the transverse movement device 22. When the transverse movement device 22 moves transversely on the welding frame 21, the welding gun 24 moves transversely, thereby causing the welding gun 24 to swing on both sides of the workpiece joint during welding. The wire feeding device 23 is installed on the welding frame 21, and the wire feeding device 23 is connected with the welding gun 24 to supply welding wire. The swing control device 25 is installed on the welding frame 21, and the welding gun 24 leans against the side of the swing control device 25. The swing control device 25 has a plurality of adjustable swing protrusions. The position change of the adjustable swing protrusion pushes the welding gun 24, thereby causing the swing amplitude of the welding gun 24 to change.

[0029] Specifically, the welding rotation system 1 includes a rotating main machine 11 and a rotating chuck 12 . The rotating chuck 12 is installed on the rotating main machine 11 . The rotating chuck 12 clamps the roller blank. The rotating main machine 11 drives the rotating chuck 12 to rotate.

[0030] Specifically, the welding frame 21 includes a bracket 211, a guide block 212 and a welding wire shaping block 213. The welding wire shaping block 213 is installed at the bottom of the bracket 211. The bracket 211 is installed on a trolley with locking wheels by bolts. The position of the welding gun 24 is adjusted by pushing the trolley. The bracket 211 can be raised and lowered on the trolley after the bolts are loosened, thereby adjusting the height of the welding gun 24 to adapt to the welding position. The guide block 212 is installed at the bottom of the welding wire shaping block 213. The transverse movement device 22 is slidably installed on the guide block 212. The wire feeding device 23 is installed on the side of the guide block 212. A shaping hole is provided on the welding wire shaping block 213. After the welding wire passes through the shaping hole, the coiled welding wire is straightened. The swing control device 25 is installed at the bottom of the guide block 212.

[0031] Specifically, the transverse moving device 22 includes a transverse moving frame 221 and a return spring 222. The transverse moving frame 221 slides laterally along the welding frame 21. Both ends of the return spring 222 are installed between the transverse moving frame 221 and the guide block 212. The action direction of the return spring 222 causes the welding gun 24 to press toward the swing control device 25, so that the transverse moving frame 221 can reciprocate. The welding gun 24 is installed on the transverse moving frame 221.

[0032] Specifically, the wire feeding device 23 includes a rotary wire feeding disk 231, a resistance bracket 232 and a resistance disk 233. The resistance bracket 232 is installed on the welding frame 21, the rotary wire feeding disk 231 is rotatably installed on the resistance bracket 232, and the resistance disk 233 is installed on the resistance bracket 232. The resistance disk 233 and the rotary wire feeding disk 231 rub against each other, so that the welding wire is tensioned and convenient for transportation. In order to maintain the friction between the resistance disk 233 and the rotary wire feeding disk 231, the resistance disk 233 is made of an elastic sheet, so as to ensure that the resistance disk 233 is continuously pressed against the rotary wire feeding disk 231. Obviously, in order to pull the welding wire through the shaping hole, a pair of traction rollers are provided on the side of the shaping hole on the welding wire shaping block 213 away from the rotary wire feeding disk 231. The pair of traction rollers are a common motor drive structure for pulling welding wire, which will not be repeated here.

[0033] Specifically, the swing control device 25 includes a swing control disk 251, a plurality of control rods 252 and a position control ring 253. The swing control disk 251 is rotatably mounted on the connecting rod on the lower side of the guide block 212. Each control rod 252 is slidably mounted on the swing control disk 251. Each control rod 252 is mounted on the position control ring 253. Each control rod 252 constitutes an adjustable swing protrusion. The adjustable swing protrusion has an arc head. The arc head enables each control rod 252 to smoothly push the welding gun 24. Pushing the position of the position control ring 253 can control the position of each control rod 252, thereby realizing the position of the adjustable swing protrusion.

[0034] Specifically, a rubber ring 2531 is provided on the outer side of the position control ring 253, so that the swing control disk 251 can press the workpiece to realize rotation. Specifically, a plurality of sliding grooves 2511 are provided on the swing control disk 251, and the side wall of each control rod 252 passes through the sliding groove 2511 and is installed on the position control ring 253. In addition, each of the position control rings 253 is provided with a position anchoring column 2532 adapted to the sliding groove 2511, and each of the position anchoring columns 2532 is pressed into the corresponding sliding groove 2511 after the position control ring 253 is sleeved on the outer periphery of the swing control disk 251. 511, thereby making each position anchoring column 2532 slide along the corresponding sliding groove 2511. It is worth noting that, in order to fix the position control ring 253 on the swing control disk 251, the end of each position anchoring column 2532 is conical, and the diameter of each position anchoring column 2532 is larger than the width of the sliding groove 2511. After each position anchoring column 2532 slides along the corresponding sliding groove 2511 and the position of the position control ring 253 is adjusted into place, each position anchoring column 2532 is locked on the sliding groove 2511, thereby controlling the swing amplitude of the welding gun 24.

[0035] In order to prevent the swing control disk 251 from being too close to the molten pool and causing damage to the swing control disk 251 and the rubber ring 2531, a swing force sleeve 241 is locked on the welding gun 24. The swing force sleeve 241 can slide up and down along the welding gun 24. The swing force sleeve 241 is locked on the welding gun 24 by screws, which makes it easy to adjust the height of the swing force sleeve 241, thereby ensuring that the swing force sleeve 241 is adjusted to fit the control rod 252.
