Engine run-in test bench and floating docking device and its adjustment assembly

Abstract

The invention provides an engine running-in test bench, a floating docking device and its adjustment assembly. The adjustment assembly includes a mounting base for fixed assembly with a mounting frame for installing a docking plate in a floating docking device and a mounting base for fixed connection with the docking plate. The connecting plate is provided with a positioning block extending in the up and down direction on the mounting base, the connecting plate has an assembly hole that is mated with the positioning block, and there is a gap between the inner hole wall of the assembly hole and the radial outer peripheral surface of the positioning block. There is a radial adjustment gap for the butt plate to carry the connecting plate to move and adjust in the radial direction of the assembly hole. Through the radial adjustment gap between the assembly hole of the connecting plate and the positioning block provided on the installation base, it can ensure that the corresponding butt plate can move in the radial direction during the docking process of the two butt plates, eliminating the axial guide structure due to self-processing The over-positioning caused by the precision can reduce the machining precision requirement of the whole floating docking device for the axial guide structure.

Description

technical field [0001] The invention relates to an engine running-in test bench, a floating docking device and an adjustment assembly thereof. Background technique [0002] After the engine assembly is completed, an off-line test must be carried out, which is commonly referred to as a run-in test at the factory. This type of test requires that the test preparation time be as short as possible to meet the rhythm requirements of the engine off-line. During the running-in test, it is necessary to complete the connection of the engine coolant, engine oil, fuel, intercooler pipelines and auxiliary equipment, complete the wiring of ECU wiring harness, starter and other devices, and the connection of intake air filter and smoke exhaust pipe. , After the test is completed, the various connections must be disassembled. Moreover, the preparation time for the running-in test is usually short, which requires manual completion of the connection of various pipelines and lines in a short ...
