Universal test stand for airtightness of disc-type engine oil coolers

Abstract

The invention relates to a universal test stand for the airtightness of disc-type engine oil coolers, and belongs to the field of automatic machinery. The test stand structurally comprises a worktable, a horizontal clamping device, a vertical clamping device and a flexible transmission device and is novel in structure and clear in operation principle. Compared with existing test devices for engineoil coolers, the test stand can fix the disc-type engine oil coolers of multiple models on the worktable, a gear can be driven by a driving motor to drive universal couplers to rotate by 360 degrees,and splines can adjust the length of the universal couplers at any time; the universal test stand can be used for detecting the airtightness of the disc-type engine oil coolers of multiple models andis simple and high in versatility, the detection efficiency and accuracy are greatly improved, and the economic benefits are obvious.

Description

technical field [0001] The invention belongs to the field of automated machinery, and relates to an airtightness test device for an oil cooler, in particular to a general test bench for the airtightness of a disc-type oil cooler. Background technique [0002] At present, most of the test benches for testing the air tightness of multi-type oil coolers are based on the shape of the gas inlet and outlet of the disc oil cooler, and the air supply device is manually adjusted. The existing mechanized automatic air tightness test benches only It can be designed according to one of the shapes, but it is impossible to complete the experiment on the same test bench for other multi-type air inlets and outlets. Manufacturing different shapes of test benches according to different shapes of air inlets and outlets will undoubtedly increase the test cost and flexibility. Low efficiency and inconspicuous efficiency have always been a difficult problem in the airtightness test of multi-model...

Problems solved by technology

[0003] The purpose of the present invention is to propose a disc-type oil cooler for the traditional multi-type disc-type oil cooler air-tightness test bench, which cannot detect the air-tightness of multi-type oil coolers at the same time, low work efficiency, and poor flexibility. Cooler air tightness universal test bench, according to different shapes and different angles of the air inlet and outlet of the disc oil cooler, perform multi-degree-of-freedom rotation, and lock the air inlet and outlet of the disc oil cooler through the plug Air supply and extraction, strong flexibility and good versatility, can meet the air tightness test of various types of disc oil coolers
