Abstract

The invention belongs to the technical field of engine cylinder body detection equipment, and particularly discloses an airtightness detection device which comprises a rack, a box body, a sealing mechanism and a detection mechanism, the box body is fixed on the rack, and a base for placing an engine cylinder body is arranged in the box body; the base is provided with a closed groove which is in sealing fit with the end face of an engine cylinder body, an air hole is formed in the position, located on the inner ring of the closed groove, of the base, and the air hole is connected with an air pump. The sealing mechanism comprises plugging heads arranged on the periphery and the upper portion of the base, the plugging heads correspond to hole sites of an engine cylinder block, and the plugging heads are connected with telescopic driving pieces. The detection mechanism comprises a water pump which is arranged on the rack and is communicated with the box body. Compared with the prior art, the device can quickly detect the air tightness of the engine cylinder, the detection process is convenient and quick to operate, and the detection result is visual and visible.

Description

technical field [0001] The invention belongs to the technical field of detection equipment for engine cylinder blocks, and specifically discloses an airtight detection device. Background technique [0002] With the acceleration of industrialization and the use of automation equipment and machinery, the application of engines is becoming more and more extensive. The engine block is indispensable in the engine, and most of the engine blocks need to be tested for air tightness after processing. The water immersion detection method is often used to detect the air tightness of the engine block. The port of the engine block is blocked, the engine block is placed in the water tank, and the inside of the cylinder is ventilated to detect whether there is any air leakage in the block. To improve the detection efficiency and ensure the detection effect, a device that can assist the air tightness detection of the engine block is needed. [0003] Most of the existing engine block airtig...
