Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a multi-freedom swinging integrated welding gun. Background Art

[0002] Welding is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. During the welding process, different welds and welding requirements require different gun movement trajectories, which requires workers to master various gun movement trajectories and move the gun stably. With the improvement of automation technology, automatic welding guns with swing functions have begun to appear on the market.

[0003] For example, a handheld oscillating welding gun (CN115533383A) disclosed in a Chinese patent includes a welding gun body, an oscillator, a handle and a walking mechanism. The welding gun body is oscillatably mounted on the oscillator, the rear end of the welding gun body is exposed from the oscillator, the oscillator and the handle are integrally or separately arranged, and a walking mechanism is arranged on the outer surface of the oscillator.

[0004] The shortcomings of the above prior art are:

[0005] Different materials, uses, and sizes of welding gaps require different welding gun trajectories. The use of an oscillator can only control the swing amplitude and frequency of the welding gun head. The trajectory of the welding gun head is single and it is difficult to adapt well to different welding working conditions. Utility Model Content

[0006] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a multi-degree-of-freedom swinging integrated welding gun.

[0007] The utility model is realized through the following technical scheme: a multi-freedom-degree swinging integrated welding gun comprises a welding gun head and a welding gun body which are separated, and a six-freedom-degree platform is connected between the welding gun head and the welding gun body.

[0008] It is further provided that: the six-degree-of-freedom platform comprises a top plate and a bottom plate, and a plurality of telescopic rods are hinged between the top plate and the bottom plate; the welding gun head is fixed on the top plate, and the welding gun body is fixedly connected to the bottom plate.

[0009] The telescopic rod is a servo motor.

[0010] There are six telescopic rods in total, and the six telescopic rods are distributed around the axis of the top plate and the bottom plate.

[0011] The plurality of telescopic rods are connected to a controller, and the controller is used to control each telescopic rod to perform telescopic movement.

[0012] The welding gun body is connected to the anti-collision mechanism through a transition installation device, and the anti-collision mechanism is installed on the adapter plate through a transition mechanism.

[0013] The beneficial effect of the utility model is that the controller independently controls each telescopic rod (servo motor) to perform telescopic movement, thereby adjusting the combined motion trajectory of the six telescopic rods, and finally enabling the welding gun head to perform a variety of complex swinging movements, ensuring that the swinging movement of the welding gun head can adapt to the welding requirements of different materials, uses, and welding gaps.
