Description

Technical Field

[0001] The present application relates to the technical field of automatic welding supporting equipment for electrolytic aluminum, and in particular to a supporting tooling based on automatic welding of an anode guide rod assembly and steel claws. Background Art

[0002] In the electrolytic aluminum production process, anode steel claws are important components of prebaked anodes and are the connecting components between anode carbon blocks and anode guide rods on the electrolytic cell. They are numerous and easy to wear out. For a long time, the anode steel claws welded on the anode guide rods need to be replaced regularly during the working process due to the harsh working environment. Usually, the replacement cycle of the anode steel claw legs is 1 year and the replacement cycle of the anode steel claws is 3 years. After a short period of use, they need to be manually welded and repaired before they can be used again.

[0003] Due to the limitations of welding technology and equipment level in the prior art, the anode steel claws welded on the anode guide rods are prone to high pressure drop at the joints, high energy consumption, and easy falling off, which not only increases the operating costs of the enterprise, but also consumes a lot of human resources. At present, with the rapid development of equipment technology in the electrolytic aluminum industry, the mechanization and automation of anode steel claw repair production has been increasingly improved. Among them, automatic welding robots that automatically align aluminum electrolytic anode steel claws with anode guide rods have also emerged. However, the prior art lacks an adaptable tooling that can match the automatic welding robot to achieve precise positioning and fixation of the anode steel claws.

[0004] The information disclosed in this background technology section is only used to deepen the understanding of the background technology of the present disclosure, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to those skilled in the art.

[0010] In some embodiments of the present disclosure, the first power source or the second power source is a motor, a pneumatic wrench, or a manual rotating ring.

[0011] In some embodiments of the present disclosure, the clamping plate is a channel steel structure.

[0012] In some embodiments of the present disclosure, the anode steel claw fixing tool for aluminum electrolysis also includes a tool base for connecting to a corresponding positioner or transfer trolley.

[0013] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0014] 1. The tooling body is equipped with an upper clamping mechanism and a lower leveling mechanism, which can not only quickly fix the anode steel claw, but also make the anode steel claw in a vertical state as a whole through the lower leveling mechanism, so as to achieve precise positioning, so as to facilitate the welding robot to weld the anode guide rod and the anode steel claw; it solves the problem of inaccurate positioning of the anode steel claw in the prior art, resulting in unstable clamping, and improves the efficiency and quality of the anode steel claw welding operation.

The first pressing mechanism cooperates with the thrust mechanism to clamp the anode steel claw 3 to fix the anode steel claw 3.

[0027] See also Figure 2 , Figure 3The first pressing mechanism includes a first transmission screw / shaft 4 and a clamping block 5. A first manual rotating ring 6 is welded to the active end of the first transmission screw / shaft 4. A corresponding first fixed screw nut 7 is provided on the tool body 1. The first manual rotating ring 6 is manually rotated by a crowbar to realize the advancement or withdrawal of the first transmission screw / shaft 4, thereby clamping or separating the anode steel claw 3. The clamping block 5 is movably connected to the passive end of the first transmission screw / shaft 4, and a through hole is opened in the center thereof to cooperate with the first transmission screw / shaft 4. A pin limit is provided at the passive end of the first transmission screw / shaft 4 to prevent the clamping block 5 from falling off. The thrust mechanism includes a fixing frame 8 and a thrust plate 9. The fixing frame 8 is fixedly connected to the tool body 1, and the thrust plate 9 is installed on the fixing frame 8. When clamping the anode steel claw 3, the clamping block 5 and the thrust plate 9 contact the top of the anode steel claw 3 to realize clamping.

[0029] The clamping plate 11 is a channel steel structure, and a through hole is opened at the connection with the passive end of the second transmission screw rod / shaft 10.

[0031] Working principle:

[0032] First, fix the tool body and the tool base on the positioner or transfer trolley, place the four-claw anode steel claw vertically on the tool body, and then rotate the first manual rotating ring to push the first transmission screw / shaft forward, and the thrust plate and the clamping block contact the anode steel claw to pre-fix the anode steel claw; rotate the second manual rotating ring to push the second transmission screw / shaft forward to level the state of the anode steel claw. When the anode steel claw is in a vertical state, push the first transmission screw / shaft forward to fix the anode steel claw. Finally, fine-tune the second transmission screw / shaft to fix the anode steel claw in a vertical state.
