Coupling alignment dial indicator clamping type fixing device

Abstract

The present invention relates to a coupling alignment dial indicator clamping type fixing device. The coupling alignment dial indicator clamping type fixing device comprises a clamping structure and an L-shaped double-dial indicator frame; the clamping mechanism comprises a fastening bolt, fastening bolt nuts, supporting seats, a supporting mechanism and a supporting block; the L-shaped double-dial indicator frame includes an L-shaped meter frame, a radial dial indicator and an axial dial indicator; and the clamping structure and the L-shaped double-dial indicator frame are connected with each other through dial indicator bolts and adjustment nuts. The coupling alignment dial indicator clamping type fixing device of the invention is mainly applied to the fixation of the radial alignment dial indicator and longitudinal alignment dial indicator of a coupling. The coupling alignment dial indicator clamping type fixing device of the invention has a wide use range and can be applied to coupling bolt holes of different sizes and different types. With the coupling alignment dial indicator clamping type fixing device adopted, the radial dial indicator and the axial dial indicator can be fixed simultaneously, the perpendicularity and parallelism of a measuring surface can be ensured, measurement errors can be greatly reduced, and the perpendicularity and parallelism of the coupling can be measured simultaneously. The coupling alignment dial indicator clamping type fixing device has the advantages of high stability, high measurement precision, low processing production costs, convenient and easy use, small size, light weight and easiness in carrying.

Description

technical field [0001] The invention relates to a centering device for a coupling, in particular to a clamping and fixing device for a dial indicator for a centering of a coupling. Background technique [0002] At present, to find the center of the coupling, the dial indicator is fixed on the magnetic base or the special tool provided by the steam turbine manufacturer. No matter what kind of tool, the dial indicator needs to be accurately fixed on the coupling in order to accurately measure the center deviation of the coupling. The fixed accuracy of the dial indicator on the coupling directly affects the accuracy of the coupling to find the center. [0003] Chinese patent CN 102901421A discloses a large-scale machine coupling centering device, which includes 1 / 2 fixed channel ring, 1 / 2 movable sliding plate, left and right measuring frames, dial indicators, bolts, screws, The 1 / 2 fixed channel circle is provided with "T"-shaped grooves, connecting plates, and screws, and t...

AI Technical Summary

Problems solved by technology

However, due to the narrowness around the coupling and the elasticity of the magnetic base, it is difficult to accurately fix the dial indicator on the coupling. It takes many adjustments to fix the dial indicator in a proper position, which consumes a lot of time. time, and the measurement error is large
