[0003] In the prior art, the electrode round billet is usually placed flat on a supporting pad, and an auxiliary electrode is hung to the side of the electrode round billet using a crane and a wire rope.

The welding process requires multiple manual assisted rolling of the electrode round billet to complete the welding of the annular weld. Before welding, it is difficult to control the concentricity of the auxiliary electrode and the electrode round billet, and it is easy to be eccentric and skewed. The auxiliary electrode hanging and welding process, the manual assisted rolling of the electrode round billet process and the eccentricity and skew of the welding will increase the safety risks of the operator.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0025] See also Figure 1 The utility model provides an electrode round billet centering device, including a bearing base 1, at least one protrusion 4 protruding from the upper surface of the bearing base 1, a first fixed seat 6 embedded in the protrusion 4, and an electrode round billet rotating wheel mechanism 2 fixedly installed on the first fixed seat 6 for supporting and rotating the electrode round billet.

[0026] A slide rail 5 is provided on the surface of the bearing base 1 on the right side of the protrusion 4. The slide rail 5 is fixed and embedded in the surface of the bearing base 1 by a clamp. An auxiliary electrode lifting wheel mechanism 3 is provided above the slide rail 5 to support and drive the auxiliary electrode to lift. The auxiliary electrode lifting wheel mechanism 3 is slidably installed on the slide rail 5 by installing a pulley 501 at the bottom of the auxiliary electrode lifting wheel mechanism 3. When the position of the auxiliary electrode lifting wheel mechanism 3 is moved, the distance between it and the electrode round billet rotating wheel mechanism 2 can be adjusted. In addition, according to the size of the electrode round billet clamped by the electrode round billet rotating wheel mechanism 2 and the auxiliary electrode clamped by the electrode lifting wheel mechanism 3, the distance between the electrode round billet and the auxiliary electrode can be adjusted in the utility model, and the adaptability to the material size is high.

[0027] At the same time, limit baffles 502 are fixedly installed at both ends of the slide rail 5 to limit the auxiliary electrode lifting wheel mechanism 3 to prevent the auxiliary electrode lifting wheel mechanism 3 from slipping out of the slide rail 5 and falling to a position outside the slide rail 5.

[0028] In addition, if a plurality of protrusions 4 are provided on the bearing base 1, a storage space can be formed between two adjacent protrusions 4, and a second fixing seat 7 is embedded at the bottom of the storage space, and the wheel rotation reduction motor 8 is fixedly installed on the second fixing seat 7, and the wheel rotation reduction motor 8 is electrically connected to the electrode round billet rotating wheel alignment mechanism 2 to drive the motor round billet rotating wheel alignment mechanism 2 to operate. The staff can also arrange a plurality of electrode round billet rotating wheel alignment mechanisms 2 and wheel rotation reduction motors 8 according to actual production needs, for example, when the size and weight parameters of the electrode round billet to be aligned are too large, so as to stably support and rotate the electrode round billet.

[0029] See also Figure 2 The utility model provides a cross-sectional view of an electrode round billet rotating wheel alignment mechanism 2, specifically, comprising: an active roller 201 and a first driven roller 202; the first driven roller 202 is fitted on the left and right sides above the active roller 201, thereby forming an inverted T-shaped roller system for supporting and driving the electrode round billet to rotate. A belt is provided at the active shaft at the center of the active roller 201, and the belt is respectively connected to the driven shaft at the center of the first driven roller 202 on both sides. When the wheel rotation reduction motor 8 drives the active shaft to rotate, the active shaft will drive the belt to rotate, and then the belt drives the driven shaft to rotate, thereby rotating the operation.

[0030] A baffle is also provided on the side of the first driven roller 202 away from the active roller 201. The benefit of such a setting is to prevent the operator from accidentally touching the baffle during operation and causing a safety accident.

The second driven rollers 302 are used to support the auxiliary electrode. When the electrode round billet rotates accordingly, the second driven rollers 302 and the auxiliary electrode are driven to rotate, thereby completing the circumferential seam welding of the entire electrode circumferential butt surface. A lifting motor 303 is provided on the side of the lifting platform 301, which is used to drive the lifting platform 301 up and down, thereby driving the auxiliary electrode on the second driven roller 302 to lift and lower, so as to accurately align with the center of the electrode round billet.
