Adjustable bracket for crankshaft detection

Abstract

The invention provides an adjustable bracket for crankshaft detection. The adjustable bracket is composed of a base (1), V-shaped iron (2), a left rotating supporting roller (4a), a right rotating supporting roller (4b), a height adjusting screw jacking rod (3) and a locking nut (5); one side of the lower end of the V-shaped iron (2) is hinged to the base (1), the lower end of the other side of the V-shaped iron (2) is provided with the screw jacking rod (3) which acts on the upper surface of the base (1) to adjust the height of the V-shaped iron (2), and the left side and the right side of a V-shaped groove of the V-shaped iron (2) are symmetrically arranged and provided with the left rotating supporting roller (4a) and the right rotating supporting roller (4b) respectively for being matched with a crankshaft neck for supporting.

Description

technical field [0001] The invention relates to an adjustable crankshaft bracket used when detecting crankshaft crank radius, runout, parallelism and other indicators on a flat plate. This bracket can quickly adjust the centerline contour of the supporting journals on both sides of the crankshaft. In order to detect crankshaft crank radius, runout, parallelism and other indicators. Background technique [0002] The existing crankshaft detection bracket is just a V-shaped iron bracket. When in use, it is placed on the detection platform and supported by two pairs of journals at both ends of the crankshaft, and then detects whether the centerlines of the two supporting journals are equal. Lift the crankshaft on the lower side of the center line, manually lift the V-shaped iron bracket, insert a feeler gauge between the bottom surface of the V-shaped iron bracket and the detection platform, then put down the crankshaft, and check whether the center lines of the two supporting ...

AI Technical Summary

Problems solved by technology

[0003] Large crankshafts, especially pier forged crankshafts, are bulky and heavy, and it is difficult to move and lift them manually during the inspection process. They are often lifted by cranes, which is cumbersome, time-consuming, and inconvenient to operate.

This method of inserting a feeler gauge between the bottom surface of the V-shaped iron support and the detection platform to adjust the centerline contour of the two support journals has a large error due to human factors, high labor intensity, and long adjustment time.

In addition, the V-shaped iron is matched with the support of the crankshaft journal, and the crankshaft needs to be rotated during detection, which has a large rotational resistance and is not convenient for crankshaft detection.
