Example Embodiment

[0025] The present invention will be further described below in conjunction with the examples.

[0026] like figure 2 , image 3 As shown, a flange position inspection tool is provided with a inspection body 1, the lower end of the inspection body 1 is connected to two main shafts V-shaped 2, and a gasket 8 is welded on the main shaft V-shaped 2, and the material of the gasket is a cemented carbide block , For example: ZK20, YW2, etc., the liner 8 and the main journal 10 on the crankshaft 9 are closely positioned to determine the centerline of the main shaft.

[0027] Check the concrete 1 and connect two connecting rod neck positioning blocks 3 on the front and rear sides respectively. The connecting rod neck positioning blocks 3 are respectively welded with gaskets 8, and the gaskets 8 and the connecting rod journal 11 on the crankshaft 9 are closely positioned to determine Connecting rod centerline.

[0028] The right side of the inspection body 1 is connected to the fla...

Abstract

The invention provides a flange position degree testing fixture, which solves the technical problem that a testing fixture cannot detect the position degree of a flange hole relative to the center line of a connecting rod neck in the existing crankshaft end face flange hole processing procedure, the testing fixture is provided with a testing fixture body, the testing fixture body is provided with a main shaft V-shaped part and a connecting rod neck positioning block, and the side surface of the testing fixture body is provided with a flange plate; the flange plate is provided with a pin hole, and the flange position degree testing fixture is also provided with a bolt. The testing fixture can be widely applied to detection of the position degree of the crankshaft flange hole relative to the connecting rod journal.

Description

technical field [0001] The invention relates to a checking tool, in particular to a flange position checking tool. Background technique [0002] The crankshaft is one of the core parts of the piston engine. It bears the force transmitted by the connecting rod and converts it into torque to drive the power output device and other accessories connected to it. Flange connection, so the end face of the crankshaft crankshaft needs to process multiple flange holes. [0003] The flange hole on the end face of the crankshaft crankshaft has a position requirement. The position reference is usually the centerline of the main journal and the centerline of the connecting rod neck. The flange position inspection tool usually used is a circular sleeve. For example, the publication number is CN103245265A The Chinese invention patent discloses a crankshaft end face inspection tool, such as figure 1 As shown, it includes a large-end measuring mechanism, a small-end tightening mechanism and...
