They are characterized by high productivity, high quality, and high stability.

[0003] A Chinese patent (publication number: CN216912439 U) discloses a wire feeding device for a damaged wire reel, which allows the wire reel of a welding robot to rotate relatively smoothly without causing the wire reel to rotate randomly or too flexibly, thereby reducing the phenomenon of scattering of the rolled welding wire. However, during the wire feeding process, welding robots currently on the market only move the welding wire through the wire reel, and the welding wire only has thrust during the wire feeding process, which can easily lead to excessive distortion of the welding wire hose of the welding robot, making it inconvenient to feed the welding wire smoothly.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 A welding wire buffer device for a welding robot in this embodiment includes a welding robot body 1 and a welding wire body 2. A placement plate 3 for placing a welding wire roll is fixed to the top of the right side of the welding robot body 1. A compaction component is provided at the right end of the welding robot body 1. A buffer component is fixed to the right side wall of the welding robot body 1.

[0024] See also Figure 4-5 The buffer assembly in this embodiment includes a concave plate 51 fixed to the right side of the welding robot body 1, the inner side of the concave plate 51 is rotatably connected to a guide wheel 52 through a bearing, the front and rear walls of the inner side of the concave plate 51 are slidably connected to concave blocks 53, the opposite ends of the front and rear concave blocks 53 are rotatably connected to a buffer wheel 54 through a bearing, a connecting block 55 is fixed to the inner side of the two concave blocks 53, a cross bar 56 is slidably connected to the inside of the connecting block 55, and a buffer spring 57 is sleeved on the outer surface of the cross bar 56.

[0025] The front and rear walls of the inner side of the concave plate 51 are each provided with two sliding holes, and the concave block 53 passes through the sliding holes to the inside of the concave plate 51 and is slidably connected thereto, so that the concave block 53 can move into the inside of the concave plate 51 through the same group of two sliding holes.

[0026] In addition, the two cross bars 56 are both located inside the concave plate 51, and the left ends of the two cross bars 56 are fixed to the left wall inside the concave plate 51, so that the cross bars 56 can support the buffer spring 57 so as to limit the position of the buffer spring 57 when it is squeezed.

[0027] Moreover, round holes are provided at the right ends of the two connecting blocks 55, and the cross bar 56 passes through the outside of the round holes and is slidably connected thereto, so that the connecting blocks 55 can slide on the outside of the cross bar 56, thereby enabling the concave block 53 to slide on the outside of the cross bar 56 through the connecting blocks 55, so that the two buffer springs 57 can provide resistance to the buffer wheel 54 through the two connecting blocks 55 and the concave block 53, so that the buffer wheel 54 and the guide wheel 52 can fit tightly with the welding wire body 2.

[0028] See also Figure 1 and Figure 3 The compaction assembly in this embodiment includes an L-shaped plate 41 fixed to the right end of the welding robot body 1, a support plate 42 is fixed to the right wall inside the L-shaped plate 41, a shift plate 43 is slidably connected to the outer surface of the support plate 42, a compaction wheel 44 is rotatably connected to the left side of the inner side of the shift plate 43 through a bearing, a limiting plate 45 is fixed to the left end of the support plate 42, two sleeve rods 46 are slidably connected to the inside of the support plate 42, and a torsion spring 47 is adjusted on the outer surface of the sleeve rod 46.

[0029] Secondly, the moving plate 43 is in a concave shape with a hollow inner cavity and a missing right end. Two sleeve rods 46 are fixed to the left wall of the inner cavity of the moving plate 43 so that the moving plate 43 can slide outside the supporting plate 42.

[0030] In addition, the front and rear walls of the inner cavity of the moving plate 43 are provided with sliding grooves, and the front and rear ends of the limiting plate 45 are located inside the sliding grooves and are slidably connected thereto. When the two torsion springs 47 push the moving plate 43 to move, the moving plate 43 can be prevented from falling off the outer surface of the support plate 42 by the two sliding grooves.

[0031] At the same time, two through holes and two slot holes are respectively opened on the left side of the limiting plate 45 and the support plate 42. The sleeve rod 46 passes through the through holes to the inside of the slot holes and is slidably connected thereto, so that the sleeve rod 46 can pass through the through holes to pass out of the interior of the limiting plate 45 and can be moved to the slot hole of the support plate 42.

[0032] The working principle of the above embodiment is:

[0033] When in use, when the welding wire is being fed, the two buffer springs 57 act as a resistance to the connecting block 55, so that the buffer spring 57 can indirectly act as a resistance to the two concave blocks 53, so that the side opposite to the buffer wheel 54 and the guide wheel 52 can be closely attached to the left and right sides of the welding wire body 2, and the welding wire generates friction with the buffer wheel 54 and the guide wheel 52 while moving. Under the action of the double friction force, the welding wire can pull the welding wire body 2 to move, ensuring that the speed of the welding wire body 2 is uniform during transportation, and when the welding wire hose is twisted too much, it can also ensure the smooth feeding of the welding wire body 2;

[0034] Among them, by moving the shift plate 43 to the right, the two sleeve rods 46 are gradually moved into the interior of the support plate 42, so that the limiting plate 45 can squeeze the two torsion springs 47, and the welding wire coil can be placed on the placement plate 3. The shift plate 43 can be loosened, and under the elastic force of the torsion springs 47, the two torsion springs 47 push the shift plate 43 to move to the left, so that the compacting wheel 44 can apply a pre-tightening force to the edge of the welding wire of the welding wire coil, and the welding wire reel will rotate relatively smoothly, and the welding wire reel will not rotate randomly or too flexibly.
