Inner chamber testing fixture for gear chamber of flywheel housing of engine

Abstract

The invention provides an inner chamber testing fixture for a gear chamber of a flywheel housing of an engine. The inner chamber testing fixture includes a frame-shaped body, wherein the frame-shaped body is corresponding to the outer contour of a gear chamber of a flywheel housing of an engine; a positioning pin 1 and a positioning pin 2 are arranged at the lower position on two sides of the frame-shaped body; the positioning pin 1 and the positioning pin 2 are corresponding to positioning mounting holes of the flywheel housing of an engine; the frame-shaped body is corresponding to the motion trail of a gear 1, the motion trail of a gear 2, the motion trail of a gear 3 and the motion trail of a gear 4 and are provided with a detection plate 1, a detection plate 2, a detection plate 3 and a detection plate 4 downwards; and a rotation handle 1, a rotation handle 2, a rotation handle 3 and a rotation handle 4 are arranged on the frame-shaped body and are corresponding to the detection plate 1, the detection plate 2, the detection plate 3 and the detection plate 4 so that the detection plate 1, the detection plate 2, the detection plate 3 and the detection plate 4 can move along the motion trails of the gear 1, the gear 2, the gear 3 and the gear 4. The inner chamber testing fixture for a gear chamber of a flywheel housing of an engine can detect the inner chamber interference problem of a gear chamber of a flywheel housing of an engine through the simulation effect of the motion trails.

Description

technical field [0001] The invention relates to the production and manufacture of an engine flywheel housing (with a gear chamber cavity structure), and relates to the inner cavity of the T9000-B flywheel housing gear chamber, in particular to the inspection tool for the inner cavity of the engine flywheel housing gear chamber. Background technique [0002] The engine T9000-B flywheel housing is made of cast aluminum alloy. For the inner cavity of the gear chamber, due to the uncertainty and error of the casting shrinkage law, the inspectors cannot pass the standard inspection tool and can only inspect it visually. The work intensity is relatively high. Yamato's production efficiency is low, and installation interference will occur during installation, resulting in the passive situation of parts being forced to go offline, return, and economic assessment. Contents of the invention [0003] In order to overcome the non-interference in the assembly of the gear chamber of the...
