A device for detecting the exhaust performance of a cylinder air exchange port for an automobile

Abstract

The invention discloses a detection device for exhaust performance of a cylinder ventilation opening for an automobile. The problems that a traditional detection device needs to manually disassemble acylinder from the automobile and then the ventilation opening is connected with the detection device in a butting mode, or an externally-connected pipeline is adopted to be directly led to the position of the cylinder ventilation opening in the automobile, the method enables a connector to be unscrewed during the connection of the externally-connected pipeline and the ventilation opening due to inconvenient manual connection, and the detection results are prone to being inaccurate due to the situation of gas leakage are solved. The detection device comprises a support and a gas supply mechanism installed in the support, a gas inlet adjusting connector connected with the gas supply mechanism is installed on one side of the support, and a detection vessel is installed on the other side of the support. The cylinder does not need to be disassembled from the automobile during detection, butting connection of the externally-connected pipe is not needed, the detection device can be directlyled to the position of the cylinder ventilation opening in the automobile, and meanwhile, gas leakage at the connecting position during butting connection can be effectively prevented.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for the exhaust performance of an automobile cylinder air exchange port. Background technique [0002] The cylinder is an important part of the car. It is necessary to install a ventilation port for ventilation on the cylinder. At the same time, the ventilation port is also an important part that needs to be tested during the quality inspection of the cylinder. Use a specific detection device to detect the exhaust performance of the cylinder ventilation port. Is it up to standard. [0003] However, there are still certain defects in the existing detection device for the exhaust performance of the cylinder air exchange port for automobiles. During the detection, it is necessary to manually disassemble the cylinder from the automobile and then connect the air exchange port with the detection device, which is cumbersome and time-consuming, or use The external pipe is directl...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an exhaust performance detection device for a cylinder air exchange port of an automobile, which can solve the problem that the traditional air cylinder air exchange port for an automobile needs to manually disassemble the cylinder from the automobile and then connect the air exchange port with the detection device. Docking is cumbersome and time-consuming, or the external pipe is used to directly lead to the position of the air exchange port of the internal cylinder of the car. Although this method is convenient, it often occurs after the external pipe and the air exchange port are connected due to the inconvenience of manual docking. The interface is not tightened and there is gas leakage, which may easily lead to inaccurate test results
