General-purpose center-correcting rack

Abstract

The invention relates to the technical field of correcting the center of an inner hole of a workpiece, in particular a universal centering rack, which mainly comprises an annular seat, a stay bolt (including a seat), a radial adjusting bolt, an axial adjusting bolt, a radial adjusting seat, an axial adjusting seat, a spherical centering rack, etc., wherein the seat of the stay bolt is welded on the annular seat; the stay bolt is fixed into the inner hole of the workpiece; the radial adjusting bolt is arranged on the annular seat and supports the radial adjusting seat; the spherical centering rack is sleeved into the radial adjusting seat, and the tail of the spherical centering rack is sleeved into the axial adjusting seat; and the axial adjusting seat is supported by the axial adjusting bolt which is arranged on the tail of the radial adjusting seat. The invention has the advantages of simple and convenient use, high precision, good commonality, capability of being suitable for various instruments, low cost and simple manufacture.

Description

technical field [0001] The invention relates to the technical field of correcting the center of a workpiece inner hole, in particular to a universal center correction stand. Background technique [0002] In shipbuilding or other industrial and agricultural production, there are often situations where the center of the inner hole of the workpiece is used to correct other related centers or the center of the inner hole of the workpiece is corrected through other related centers. For example, in shipbuilding, the positioning of the epoxy cast fixed stern tube assembly and the guy wire sighting determine the shafting center at various other locations. At present, more advanced instruments such as laser instruments, flat telescopes, and dial indicators are mostly used, and they all need to work together with the center correction frame to complete, while the traditional center correction frame is also used for axial angle adjustment through radial adjustment. , and when adjustin...

AI Technical Summary

Problems solved by technology

At present, most advanced instruments such as laser instruments, flat telescopes, and dial indicators are used, and they all need to work together with the central correction frame to complete, while the traditional central correction frame is also used for axial angle adjustment through radial adjustment. , and when adjusting the axial angle, it will definitely affect the adjusted radial position. Similarly, when making radial adjustment, it will definitely affect the adjusted axial angle position, so it is necessary to adjust the inner position of the center correction frame The two positions of the radial and axial angles of the hole need to be adjusted repeatedly, so it is complicated, the adjustment time is long, the accuracy is relatively low, and the requirements for the operator are also high.
