Air tightness detection equipment for precise aluminum casting

Abstract

The invention discloses airtightness detection equipment for a precise aluminum casting, and relates to the field of airtightness detection equipment, the airtightness detection equipment comprises a detection box, the precise aluminum casting in the device is placed in a detection cavity, the detection cavity is filled with lubricating oil, the lubricating oil in the detection cavity can be filled into a gap of the precise aluminum casting when being pressurized, and the detection box is arranged in the detection cavity. When lubricating oil liquid enters a gap of the precision aluminum casting, air is exhausted, and the monitoring assembly can monitor bubbles, so that whether the air tightness of the precision aluminum casting is good or not is judged, the air leakage position of the precision aluminum casting is judged, and when the position of the precision aluminum casting is judged, the air tightness of the precision aluminum casting is detected. The air leakage position is repaired through the repairing assembly, the air tightness of the precision aluminum casting can be continuously detected after repairing, and air tightness detection, repairing and re-detection of the precision aluminum casting are achieved.

Description

technical field [0001] The invention relates to the field of airtightness testing equipment, in particular to an airtightness testing equipment for precision aluminum castings. Background technique [0002] Aluminum castings refer to equipment and devices made of pure aluminum or aluminum alloys obtained by casting. Generally, sand molds or metal molds are used to pour aluminum or aluminum alloys heated into liquid into the mold cavity to obtain various shapes. Aluminum parts or aluminum alloy parts of the same size are usually called aluminum die castings. During the processing of aluminum castings, it is necessary to perform tightness testing operations on the produced aluminum castings, which requires a special air tightness testing device for aluminum castings. However, the traditional airtightness testing device for aluminum castings has many deficiencies, such as cumbersome operation, inconvenient opening and closing detection, and cannot ensure the airtightness of the...

[0002]Aluminum castings refer to equipment and devices made of pure aluminum or aluminum alloys obtained by casting. Generally, sand molds or metal molds are used to heat them into liquid Aluminum or aluminum alloy is poured into the mold cavity, and the obtained aluminum parts or aluminum alloy parts of various shapes and sizes are usually called aluminum die castings. During the processing of aluminum castings, the tightness of the produced aluminum casting products is required Inspection operation, which requires a special aluminum casting air tightness detection device to assist, but the traditional aluminum casting air tightness detection device has many shortcomings, the operation is cumbersome, it is not convenient for opening and closing detection, and it cannot ensure the airtightness of the joint Therefore, the accuracy of the internal air tightness test cannot be guaranteed, and the structural design is not reasonable enough
