A device capable of flexibly detecting the airtightness of an exhaust manifold and its application method

Abstract

The invention provides equipment capable of flexibly detecting air tightness of exhaust manifolds and an application method. The equipment comprises a detection cart, a starter and an alarm. A plurality of vertical and horizontal slide ways are arranged on three faces of the detection cart, and extend inwardly to form a plurality of clamping devices and sealing devices with claws. The clamping devices and the sealing devices are connected with a power device. The tail of the power device penetrates the vertical and horizontal slide ways and move on the vertical and horizontal slide ways. The detection cart is provided with an automatic water injection pipe fitting and an automatic air delivery pipe fitting. The starter and the alarm are arranged on the outer side of the detection cart, andare connected with a control system through sensors. A water tank is arranged on the bottom surface of the detection cart. High-pressure water compression is applied to detect the air tightness of the manifolds, adjustment can be made flexibly according to differences of the detected manifolds, and the equipment has the advantages of visual and obvious detection effect and applicability to various automotive exhaust manifolds.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to a device capable of flexibly detecting the airtightness of an exhaust manifold and a use method thereof. Background technique [0002] The exhaust manifold is connected to the cylinder block of the automobile engine, and the exhaust gas discharged from each cylinder is collected and introduced into the exhaust main pipe, with a conduit with branch lines. At present, the common practice of various engine manufacturers is to package the three-way catalytic converter used to purify the exhaust gas in the exhaust manifold. If the airtightness of the exhaust manifold is not good, the exhaust gas will not only pollute the car body, but also reduce the exhaust gas of the vehicle. System life, more seriously, will cause pollution to the atmospheric environment. After the finished exhaust manifold is completed, it needs to pass the air tightness test. In the existing technology, the exh...

Problems solved by technology

However, the former has the risk of radiation injury and requires higher professional quality of operators; the latter is affected by the fixed position and number of sealing devices, and a single device can generally only test the airtightness of exhaust manifolds of a series of cylinders. The flexibility is poor, and the specific leakage point cannot be accurately judged, which affects the use effect
