Novel cooling bed moving tooth low-speed shaft key position measuring device

Abstract

The invention provides a novel cooling bed moving tooth low-speed shaft key position measuring device which comprises a base, a stepped hole, mounting bolts, mounting rods, semicircular angle measuring scales, threaded round rods and measuring line cones, the base is fixed to a key groove of a low-speed shaft through the mounting bolts, the mounting rods are symmetrically arranged on one side of the base, the semicircular angle measuring scale is arranged on one side of each mounting rod, angle scales are arranged on the front surface and the back surface of each semicircular angle measuring scale, a threaded round rod is arranged on the other side of each mounting rod, a measuring rope is fixed on each threaded round rod, and a measuring line cone is arranged at the lower end of each measuring rope. The measuring device has the advantages of being simple in structure and convenient to measure and operate, no professional technology or theory is needed for supporting, the angle of each low-speed shaft eccentric wheel can be accurately measured through the semicircular angle measuring scales, the threaded round rods, the measuring ropes and the measuring line cones, and therefore the purpose that the angles of the low-speed shafts of the whole cooling bed are consistent is achieved.

Description

technical field [0001] The invention relates to the field of measuring devices, in particular to a novel device for measuring the key position of a low-speed shaft of a movable tooth of a cooling bed. Background technique [0002] The cooling bed is a work surface for effectively cooling rolled products (rebar, round steel, steel pipe, etc.) in the metallurgical rolling industry. The cooling bed is composed of a mechanical transmission system, a water cooling system, a cooling bed work surface, and a fixed bracket; The beds mainly include tooth-drawing cooling beds, rack-type cooling beds, claw-type cooling beds, carrying chain cooling beds, rolling plate cooling beds, etc.; [0003] Due to the design of the moving teeth of a cooling bed, the tooth pitch of the rack is only 80mm. One bar has been rolled for a long time with Ф12, Ф14 and Ф16 in three cuts, especially when rolling Ф16 three cuts, three Ф16 rebars are placed in the moving When the rack is on the distribution a...

AI Technical Summary

Problems solved by technology

[0005] In daily maintenance, due to the replacement of the low-speed shaft and the inspection of the coupling, the keyway of the low-speed shaft will be misaligned. When adjusting the misalignment of the keyway, because there is no professional measuring tool, the position of the keyway is often determined visually, resulting in the keyway being adjusted. The back is not at the same angle, causing the dislocation of the movable teeth of the cooling bed; therefore, the present invention proposes a new type of key position measuring device for the low-speed shaft of the movable teeth of the cooling bed to solve the deficiencies in the prior art
