Problems solved by technology
[0003] Most of the existing engine block airtightness testing is carried out on the airtightness testing table, that is, the lower opening of the engine block is sealed first, then the engine block is placed on the airtightness testing table, and then The sealing cover with the detection head of the air tightness tester is sealed with the upper end of the engine block, and then the engine is tested by the air tightness tester. Most of the engine testers are docked manually, resulting in a long time for docking. At the same time, the accuracy of the docking is poor, which easily affects the air tightness detection accuracy of the engine

The invention relates to an engine cylinder body air tightness detection machine capable of automatic docking. An air tightness detection seat is arranged on the frame, and a bottom supporting device cooperating with the engine cylinder body is arranged on the bottom of the airtightness detection seat. An airtightness detection lifting device is provided, and a side clamp that cooperates with the engine cylinder on the bottom support device is provided on the side, and an airtightness detection device that cooperates with the engine cylinder is connected under the airtightness detection lifting device , the bottom support device includes a bottom support block arranged on the air tightness detection seat, a bottom seal block is provided on the bottom support plate, and a sealing hole for interference fit with the lower end of the engine cylinder is opened on the bottom seal block. The present invention can The bottom of the engine block is sealed, and the engine block can be positioned, so that it can be accurately and automatically docked with the detection device installed on the air tightness detection lifting device, which improves the detection efficiency and detection accuracy.
Description
technical field [0001] The invention relates to the field of engine block processing equipment, in particular to an engine block airtightness detector capable of automatic docking. Background technique [0002] With the advancement of industrialization, 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. [0003] Most of the existing engine block airtightness testing is carried out on the airtightness testing table, that is, the lower opening of the engine block is sealed first, then the engine block is placed on the airtightness testing table, and then The sealing cover with the detection head of the air tightness tester is sealed with the upper end of the engine block, and then the engine is tested by the air tightness tester. Most of the engine testers are docked manually, resulting in a long time for docking. At the same time, ...
