After the installation is completed, the connection position of the coupling needs to be calibrated, and the installation efficiency is low. For this reason, we propose a high-speed wire rolling mill coupling. Utility Model Content

[0012] Beneficial effects

[0013] The utility model provides a high-speed wire rolling mill coupling. It has the following beneficial effects:

[0014] (1) The high-speed wire rolling mill coupling places the two shafts to be connected into the two first locking blocks respectively, installs the second locking block through the guiding structure, and adjusts the distance between the two shafts by moving the first movable rod inside the connecting sleeve, so that the corresponding sides of the calibration block and the adapter block are pressed against each other. When the inclined surface of the calibration block and the inclined surface of the adapter block are pressed against each other, the center positions of the calibration block and the adapter block will coincide. The calibration block and the adapter block are matched through taper during the process of mutual extrusion, which increases the contact area between the calibration block and the adapter block and improves the installation efficiency.

[0015] (2) In the high-wire rolling mill coupling, the threaded rod drives the second movable rod to rotate inside the movable cavity. When the threaded rod rotates inside the threaded hole, the second movable rod drives the calibration block to move toward the position of the adapter block, so that the calibration block and the adapter block fit together. The force applied by the threaded rod is at the center position of the calibration block and the adapter block, so that the contact force between the calibration block and the adapter block is more uniform, thereby improving the stability during operation.
