DETAILED DESCRIPTION

[0016] 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.

[0017] See also Figure 1-2 As shown, the stably supported welding gun lifting mechanism in this embodiment includes a base 1, a support sleeve 2, a lifting motor 3, a screw 4, a welding gun suspension frame 5, a support rod 6 and a driving assembly. The support sleeve 2 is vertically arranged above the base 1, the lifting motor 3 is arranged above the support sleeve 2, and the screw 4 is vertically arranged inside the support sleeve 2, and the upper end is transmission-connected to the lifting motor 3, and the lower end is rotationally connected to the bottom of the support sleeve 2; a slide groove 7 is provided on one side of the support sleeve 2, and the welding gun suspension frame 5 is transmission-connected to the screw 4 through a nut 8, and driven by the lifting motor 3, the welding gun suspension frame 5 can slide back and forth up and down along the slide groove 7, thereby realizing the adjustment of the welding gun height.

[0018] The support rod 6 is arranged on both sides of the base 1, the driving component is arranged on the base 1 and is transmission-connected with the support rod 6, and grooves 9 for the support rod 6 to flip are provided on both sides of the base 1. Driven by the driving component, the support rod 6 can flip up and down along the groove 9.

[0019] A support block 10 is provided at the end of the support rod 6, and an anti-sliding block 11 is provided at the bottom of the support block 10. The anti-sliding block 11 can increase the friction between the support block 10 and the ground to prevent the base 1 from moving during use.

[0020] The bottom of the base 1 is also provided with casters 12 , and when moving, the support rod 6 can be folded up and moved by the casters 12 .

[0021] like Figure 2 As shown, the driving assembly includes a driving motor 13, a driving rod 14, a first transmission rod 15 and a second transmission rod 16. The driving motor 13 is fixedly arranged on the base 1, and the driving rod 14 is laterally arranged on the base 1, and is transmission-connected to the driving motor 13 in the middle position, and is transmission-connected to the first transmission rod 15 and the second transmission rod 16 at both ends respectively, and the first transmission rod 15 and the second transmission rod 16 are transmission-connected to the support rods 6 on both sides respectively.

[0022] A first bevel tooth 17 is respectively disposed at both ends of the driving rod 14 , and a second bevel tooth 18 is respectively disposed at one end of the first transmission rod 15 and the second transmission rod 16 . The first bevel tooth 17 and the second bevel tooth 18 are meshed for transmission.

[0023] When the driving motor 13 drives the driving rod 14 to rotate, the first bevel teeth 17 at both ends drive the second bevel teeth 18 to rotate, and further drive the first transmission rod 15 and the second transmission rod 16 to rotate, thereby driving the support rod 6 to flip. When in use, the driving assembly drives the support rod 6 to flip toward the ground side, so that the support block 10 contacts the ground, and the position of the lifting mechanism is fixed by the friction between the anti-sliding block 11 and the ground; when moving, the driving assembly runs in the reverse direction, driving the support rod 6 to flip toward the support sleeve 2 side, and the support rod 6 can be retracted, which saves space and facilitates the movement of the lifting mechanism.
