Description

Technical Field

[0001] The utility model relates to the technical field of assembly and adjustment of couplings, in particular to an assembly and adjustment device for couplings. Background Art

[0002] Coupling alignment is also called concentricity. After the pump and motor are installed, the last task is to align the pump and the motor, that is, to make the axis of the pump and the prime mover in the same straight line so that they do not vibrate during operation. There are usually two ways to align the coupling. One is to use a ruler to measure the coaxiality error of the coupling and to use a plug gauge to measure the parallelism error of the coupling. Although this method is simple, it has a large error and is generally used for machines with low speed and low precision requirements. The second is to use two gauges for alignment. Although the double gauge alignment has high accuracy, the axial displacement is sometimes difficult to grasp and is not friendly to novices, resulting in low efficiency in the axial displacement adjustment operation.

[0003] Therefore, it is necessary to design an assembly and adjustment device for a coupling to solve the above-mentioned problems. Utility Model Content

[0007] As a preferred solution of the utility model, the reference axis mounting frame and the radial meter measuring mounting frame are arranged in parallel, the reference axis mounting frame and the biaxial meter measuring mounting frame are arranged vertically, the biaxial meter measuring mounting frame is installed through the reference axis mounting frame at one end close to the adjusted axis, the radial meter measuring mounting frame is installed through one end of the axial frame body, the first axial meter body and the second axial meter body are respectively installed through the axial frame body close to both ends, and the first axial meter body and the second axial meter body are arranged horizontally.

[0008] As a preferred solution of the utility model, the axial frame body includes a central rod, and a first adjustment rod and a second adjustment rod are movably installed at the upper and lower ends of the central rod respectively.

[0009] As a preferred solution of the utility model, the first adjusting rod, the second adjusting rod and the center rod are all slidably connected by a telescopic sliding rod, and the outer surface of the center rod near both ends is spirally installed with axial locking bolts, and the outer surface of the axial frame body is spirally installed with radial frame positioning bolts near the radial meter measurement mounting frame.

[0010] As a preferred solution of the utility model, the reference shaft mounting frame includes a reference shaft mounting sleeve mounted on the assembly end of the reference shaft, the reference shaft mounting sleeve is fixedly installed with a fixed shaft rod near the axis center of one end face of the adjusted shaft, and the end of the fixed shaft rod away from the reference shaft mounting sleeve is movably installed with a mounting shaft rod through a telescopic shaft rod.
