Description

Technical Field

[0001] The invention belongs to the technical field of engine cooling nozzle detection, and particularly relates to a cooling nozzle detection tool. Background Art

[0002] The engine's lubricating oil is sprayed from the cooling nozzle into the piston's inner cooling oil passage to cool the piston and prevent the piston from melting due to high temperature. The cooling nozzle's nozzle pipe needs to be precisely aligned with the piston's oil passage. If the nozzle pipe and the piston's oil passage are not aligned, the lubricating oil cannot enter the inner cooling oil passage, causing the piston to fail due to high temperature. At the same time, the gap between the cooling nozzle's nozzle pipe and the crankshaft balance block is small, making interference easy. During the cooling nozzle assembly process, it is difficult to detect whether the cooling nozzle oil pipe is aligned with the piston's inner cooling oil passage, or whether the cooling nozzle oil pipe and the balance block are interfering. Therefore, before assembling the cooling nozzle, a test fixture is required to simulate the piston oil pipe and balance block to detect whether the cooling nozzle is aligned with the piston's oil hole and whether there is interference with the balance block. Summary of the Invention
