The invention relates to a roller seat locking device, which comprises a pressure plate, wherein the adjacent two sides of the pressure plate both have a waist-shaped hole, the pressure plate also has a through hole, a locking sleeve is arranged in the through hole, the inside of the locking sleeve is connected with a rotating screw, and the external circumferential face of the locking sleeve has a toothed structure; the end with the waist-shaped hole of the pressure plate is provided with a locking plate, one end of the locking plate has a plurality of grooves, the groove is matched and locked with the toothed structure on the external circumferential face of the locking sleeve, and the locking plate has a plurality of slotted holes which are arranged obliquely; and after the pressure plate is connected with the locking plate, the waist-shaped holes of the pressure plate are matched and connected with the slotted holes of the locking plate, and guide posts which can slide along the waist-shaped holes are arranged in the slotted holes. In the invention, the pressure plate and a roller bearing block can be locked by regulating an adjustable screw, the locking is reliable, the time-consuming, labor-consuming and complex locking device in the prior art is simplified, the working efficiency is improved, the whole mounting and working process is simple and convenient, and the roller seat locking device is safe and reliable.
Description
technical field [0001] The invention relates to the field of rolling mill equipment, in particular to a locking device for a roll stand in the rolling mill equipment. Background technique [0002] The roll system is composed of backup rolls, intermediate rolls and work rolls, and is an important part of the rolling mill equipment. When the rolling mill equipment is working, the working rolls, intermediate rolls, and backup rolls in the roll system are always subject to changes in direction and size. rolling force. Before rolling, the roll seat needs to be locked and positioned to prevent movement during its working process. At present, the commonly used locking device for the roller seat in the prior art is to punch holes on the supporting surface (frame) of the roller seat, and connect the pressure plate to the supporting surface through studs. Since each supporting surface is arc-shaped, and Inclined installation, drilling is very inconvenient, and the positioning is unr...
