Alignment device for installation of coupling

Abstract

The invention provides an alignment device for installation of a coupling. The alignment device comprises a guide part, a probe, a support piece and elastic pieces; the probe is movably arranged in the guide part, and the two ends of the probe are exposed out of the two ends of the guide part; the probe is provided with scale segments which comprise a zero scale line and positive number scale lines and negative number scale lines which are distributed at the two sides of the zero scale line respectively; the elastic pieces are arranged in the guide part and elastically support the probe in the sliding direction of the probe; the support piece comprises a first support segment and a second support segment which are connected with each other, the bottom end of the second support segment serves as a first contact end, the bottom end of the probe serves as a second contact end, and the first contact end and the second contact end are located in the same plane which is perpendicular to the moving direction of the probe; the first support segment is movably matched with the guide part to adjust the distance between the first contact end and the second contact end; the zero scale line is flush with the end face of the top end of the guide part. According to the alignment device for installation of the coupling, the contradiction between the fact that the equipment size is smaller and smaller and the fact that a dial indicator needs larger installation and operation space when the dial indicator is installed on the site can be relieved.

Description

technical field [0001] The invention relates to the technical field of shaft coupling installation, in particular to an alignment device for shaft coupling installation. Background technique [0002] In the field of mechanical equipment manufacturing, couplings are widely used in equipment connection as a relatively common connection. The coupling consists of two mating flanges. In the process of connecting the two shafts, each butt flange is fixedly connected to the corresponding shaft, and the two butt flanges are then fixedly connected by a bolt assembly, and finally the mutual fixing of the two shafts is realized. In the actual installation process, after the two butt flanges are usually fixedly connected to the corresponding shafts, it is necessary to align the two butt flanges so that the corresponding connection holes on the two flanges are aligned. Finally, it is convenient for the bolt to pass through the corresponding hole to realize the fixed connection. The so...

Problems solved by technology

However, as the current equipment becomes more and more sophisticated, the size of some equipment is getting smaller and smaller, correspondingly, the size of the coupling used in these equipment is getting smaller and smaller

Since the dial indicator needs to be installed on-site at the position to be measured through the adjustment rod and the mounting seat, and the size of the above-mentioned equipment is small, the size of the coupling will be correspondingly small, which requires the operator to install the adjustment rod on the docking flange , the operating space of the mounting base and the dial indicator is relatively limited, and even the installation cannot be realized, which eventually makes it difficult to implement the measurement with the dial indicator
