Problems solved by technology
[0002] Due to the unreasonable design of the inner bolt positioning used for the installation of the original tundish stopper rod mechanism, the length embedded in the positioning plate is not enough. In addition, the installation position of the 24 positioning bolts is not accurate enough when making the tundish, and the bolts are under the action of unbalanced external force. easy to fall off
After re-welding, the level is uneven, the stopper mechanism is not stable after installation, and the verticality of the stopper is poor, which often causes stopper control to fail, and in serious cases cannot meet the requirements of continuous casting automatic control
Due to the installation problem of the mechanism, the pouring failed many times, and the blockage often occurred, which affected the flow rate of 6 machines and 6, and was forced to replace the tundish many times, resulting in an increase in the cost of the enterprise.

The invention discloses a quick and accurate positioning device for a tundish stopper mechanism. The quick and accurate positioning device comprises a positioning plate, a connecting rod and a positioning bolt, and the connecting rod is arranged on the positioning plate; the quick and accurate positioning device further comprises a connecting block, a notch allowing the positioning bolt to penetrate through is formed in the connecting block, a welding face is arranged on one face of the connecting block, and the other face of the connecting block faces the positioning plate; and a positioninglocking groove is further formed in the positioning plate, an opening section is arranged on the outer side of the positioning locking groove, a locking section is arranged on the inner side of the positioning locking groove, and the positioning bolt penetrates through the notch and the locking section to connect the connecting block and the positioning plate together through a bolt. According tothe quick and accurate positioning device, the tundish consumption and the production halt cost caused by equipment failure can be reduced, the economic cost is effectively saved for enterprises, andthe workload of operators is reduced.
Description
technical field [0001] The invention relates to the technical field of tundish positioning, in particular to a fast and precise positioning device for a tundish stopper mechanism. Background technique [0002] Due to the unreasonable design of the original tundish plug rod mechanism, the internal bolts were not long enough to be embedded in the positioning plate. In addition, the installation positions of the 24 positioning bolts were not accurate enough when the tundish was made, and the bolts were affected by unbalanced external forces. Very easy to fall off. After re-welding, it is uneven, the stopper mechanism is not stable after installation, and the verticality of the stopper is poor, which often causes the control of the stopper to fail. In severe cases, it cannot meet the requirements of automatic control of continuous casting. Due to the installation problem of the mechanism, many pouring failures have occurred, and flow blockage often occurs, which affects the flo...
