Problems solved by technology

The defect of this method is that the center point of the end surface of the gear shaft is used as the center line of the gear shaft, that is, the line is replaced by a point. Therefore, after alignment in this way, the center line of the gear shaft does not coincide with the center line of the frame window, and it is often two straight lines that intersect, and are not completely aligned

Abstract

The invention provides a center line alignment device for a frame and a gearbox drive shaft in a rolling mill and an alignment method employing the same. The device comprises an auxiliary long shaft body (1) in a rod shape; one end of the auxiliary long shaft body (1) can be nested in a sleeve portion (3) on a gearbox drive shaft end portion (2); a plurality of measuring marker rods (13) are disposed on the auxiliary long shaft body (1) and are arranged at intervals; the measuring marker rods (13) are all perpendicular to the auxiliary long shaft body (1). The center line alignment device is simple in structure, allows center line alignment of the frame and gearbox drive shaft in the rolling mill, and allows rolls and a gear box in the rolling mill to be installed at accurate angle; the alignment method is simple to operate and high in operating efficiency.

Description

technical field [0001] The invention belongs to the technical field of rolling mill equipment, and more specifically relates to a device for aligning the center line of a rolling mill frame and a transmission shaft of a gearbox, and also relates to a method for aligning using the device. Background technique [0002] There are open type and closed type for small and medium-sized section steel fixed rolling mills. This type of rolling mill frame is fixed to the foundation base with bolts. Usually, after one alignment, it can be used for one cycle. When the equipment is repaired next time, the gear box After reset and installation again, the rack still needs to be re-aligned and fixed. When replacing the rolls of this type of rolling mill, the frame does not move, and only the roll system is replaced. If the frame is not aligned properly, it will cause a large partial load and local stress on the roll head and the joint (coupling). If it is larger, the wear of the roll head a...
