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

Embodiment 1

[0032] A device that can flexibly detect the airtightness of an exhaust manifold, including a detection car 1, a starter and an alarm 2; the three sides of the detection car 1 are provided with a plurality of vertical and horizontal slides 11, and the vertical and horizontal slides 11 are inward Stretch out a plurality of clamping devices 5, and sealing device 7 with hook claw 16; Described clamping device 5 and sealing device 7 are connected with power unit respectively, and the tail of described power unit runs through vertical and horizontal slideway 11, and in described vertical and horizontal Move on the slideway 11; the detection car 1 is provided with an automatic water injection pipe fitting 8 and an automatic gas delivery pipe part 3; the starter and the device alarm 2 are arranged on the outside of the detection car, and are connected to the control system through a sensor; the detection car 1 The bottom surface is provided with a water tank 9 . The power unit includ...

Embodiment 2

[0036] The second embodiment is basically the same in structure and principle as the first embodiment, except that the clamping device 5 and the support base 10 are provided with electromagnetic coils inside. After placing the branch port of the exhaust manifold to be tested upright on the support base 10, the clamping device 5 and the electromagnetic coil inside the support base 10 are energized to form an electromagnet, which attracts the exhaust manifold to initially fix the exhaust manifold to be tested. exhaust manifold.

Embodiment 3

[0038] The third embodiment is basically the same in structure and principle as the first embodiment, except that the automatic gas delivery pipe 3 is provided with a high-power heating wire 19 and a pressure relief valve 20 inside. After completing the leak detection, open the pressure relief valve to release the pressure 20, discharge the water in the exhaust manifold, start the high-power heating wire 19, blow hot air into the exhaust manifold, and dry the residual moisture.

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...
